Tensei shitara Slime Datta Ken

Similarities: >Protagonists are in their mid-late 30s. (Both of them are also named Satoru lol) Both are also virgins who never had a girlfriend. >They're both overpowered. >Both have extremely loyal subordinates. >Both of them build a country from scratch. >Both are good natured people but take extreme action when needed. >Both have the potential and ability to create a harem, but refrain from doing so for valid and personal reasons. >Both of them unknowingly/accidentally end up doing incredible things. Differences: >Overlord is more dark themed while TenSura is more light, with occasional dark theme spikes. >Rimuru prioritizes friendship and good ties more than overpowering new acquaintances. >Momonga is overpowered from the start and has no power growth, whereas Rimuru is overpowered only in his vicinity and has to grow to keep up with increasingly powerful enemies. >TenSura protagonist dies in his old world whereas Overlord protagonist (most likely) does not. >The New World in Overlord is more game-like (levels and such) than the world in TenSura >Momonga is an overbearing undead skeleton while Rimuru is a cute harmless looking slime. read more 

Both have very powerfull MC's, both MC's are empire builders. 

Both are about a very very very op main charater whose a monster that leads a county of monsters, both main characters were also adult humans before they got Reborn into this new world, the one different between two is Slime more nice and fun anime well overlord is more dark. 

Almost the same premise without the shitty secondary characters stories (lizard men arc) and without the horrible CGI that ruins the series 

Both have overpowered main characters, challenges, and good writing! The excel in this genre of isekai and are actually original despite how repetetive one could think this genre is. In Overlord, the main character acts more like a villain, showing the perspective of a "bad guy". While in Tensei shitara Slime Datta Ken, the main character is more of a good guy. Both anime has good characters and story. I don't know what to add if you like having overpowered mc and the isekai genre then just go ahead and watch everything :) 

Both series feature mid-30's salarymen being reborn as an OP monster in a JRPG-based fantasy world. The MC is gifted with extraordinary skills right off the bat and wields god-like abilities (much to the dismay of the supporting cast). The MC gains a large, ever-increasing number of devout followers (harem time). It's also noteworthy that in both series the MC rules over a group of superior non-humans/monsters. Basically, this anime caters to your ultimate escapist fantasy/fetish/wet dream. And it's pretty dope. 

Many people compare SAO to Overlord. But it's just wrong. Overlord, as well as Slime is a "macro" oriented MMO anime. That means, they both enter this world they aren't exactly sure of the rules they are under, but both are immenesly powerful. It's not really a problem for the viewer, because that's not really what the anime is all about. It's about how the entire world around them react to their power, and how they use what they have recieved. They both have this underlying shadow of mystery enemies that you have not met yet, that are possibly as strong as them. In similar manner, they face eachother in a "macro" battlefield, much like an RTS game, and try to figure eachother out. Both games have just begun, which makes me pshyched for the continutation of both series.  read more 

MC super OP Reborn in a fantasy world Gathers (or has) loyal and powerful followers MC is generally a decent bloke No harem Overlord starts to get a bit more anti-hero later on. 

It is similar because in Tensei Shitara Slime Datta Ken Rimuru built his own country like Overlord that Ains start to create his own kingdom. 

In Overlord you got more brutal attitude of overpowered protagonist to obeying all world to himself, and in "the slime anime" main character is a little bit mild to enemies. Both are worth watching, mainly because of this aspect. Enjoy! 

> GOD mc > strong subordinate > wants to develop their kingdom > easily stupds humans everywhere challenge them everytime (and lost) 

- Both very OP - Non-human - Both in their 30s - Loyal Followers Just watch it! 

1.Overpowered main character. 2.Main character's intentions are often misunderstood by their subordinates and others making the main characters seem to possess very high intelligence even though that is not the case always. 3.Both of them are isekai anime. 

- The main characters are both very powerful - They are leader of a group - The other characters are emotionally attached and adore the main character - They come from the real world, and they go in a fantasy world (Isekai) - Fantasy anime - They have a big impact on their universe  

same -exploring the new world they have to live in -loyal and likable subordinate -the main character are both OP -the skill each mc use are both very unique and creative -SASUGA (mc name) -the mc are both not human (in the new world) -the mc loves their subordinate -the OP and ED of both anime are top notch different -overlord at start ainz sama is already super OP while the mc from that time i was reincarnated as slime grow a little a little as the mc fights -overlord is more dark than that time i was reincarnated as slime -in overlord the story focus on alot of the character and sometimes doesnt have alot of screen time for ainz sama but in that time i was reincarnated as slime the story focus on the mc more read more 

both anime figure 30s men that are isekai one through death and reincarnation and the other summoned or similar transported. both MC are non-human one is a slime the other an un-dead skeleton. Both MC find themselves leading other monsters and struggle as both where middle management. both have at least two of their female underlings competing to be the MC wife/lover the main difference between the anime is the tone Overlord is much darker and the MC could almost be seen as an anti-hero while Slime the MC does his best to make everything work out  

Both Mcs are loner humans that get trapped in a fantasy world in an inhuman/monstrous body. And With their overpowered abilities they start their conquest of said Fantasy world. 

Both are Isekai with an op mc set in a fantasy world 

Both have an OP MC who obliterates everything in his path (Isekai) with an entourage they build over time. Both have a fair share of comedy and light heartedness Both have aspects of world building and just like in Overlord, Rimuru wants to find out other people who have come to the new world like him. The only major difference is that Rimuru is the good guy in the anime whereas in Overlord we see the world through the eyes of the bad guy 

Both set in different worlds Both MC are OP Both MC learn their new world 

Overpowered main character from different world. Subordinates are loyal to him. Main character plans to build nation.  

Things in common:- 1. Both are Isekai 2. Both have overpowered characters 3. MCs of both anime have similar mindset 4. MC of both animes are non-human 5. They have similar aims. *Slime is just less vigorous overlord* If u liked Slime and want more bloodshed or vigorousness then go for overlord  

both have hilarous character, but i more like tensei shitara slime datta ken, its more light story and good looking animation 

If you like overlord i think you will like this. Its more about comedy and it looks solid after the first episode and it will go on for 24 episodes. Anyways i would recommend to watch one episode of it to see if you like it.  

Same isekai feeling. Both characters are trying to establish a nation and they both have strong loyal servants 

Two shows which approach the idea of an isekai character running a country from a different direction. Although both of these are comedies slime tends to be a lot more light-hearted. With overlord being much more certain about being a villain who aims to expand his borders. 

"Tensei Slime is just Overlord on a Lawful Good playthrough." In both series, the main character is purposely made to be extremely overpowered, to the point of having little to nothing that poses an actual threat to them. As a result, the conflicts in both series have to come largely from something other than fight scenes, since we all know who will win the vast majority of the time; instead, both series focus on what one would do if they had that kind of power. Inevitably, that kind of combat power grants you political power, and both MC's become leaders of a group that follows them religiously (albeit in very different ways). While in Overlord, Ainz chooses to use this power to take over the world, Rimuru Tempest is an optimistic, compassionate guy who can't say no when he's asked for help. Tensei Slime has all of the politics, comedy and badass moments of Overlord, with none of the torture, sadism or purposely unlikable characters. It's an easy series to sit back and relax to, and enjoy an adorable little slime kick ass and lead a village to greatness. read more 

-both isekai anime -both mc's are not the goody two shoes that we are used to they are evil but not horror level evil, as in not human but an undead/monster that people are afraid of. -Both mc's get surrounded by some interesting outspoken characters,that get attached to our mc's. -one difference is that in overlord the mc is a maxed out badass from the get go but keeps it lowkey, the slime 'farms' and gets quite stronger with each passing episode.thankfully the 'farming' is edited nicely to not become boring.  

Isekai OP MC Worldbuilding Honesty two of the best anime I've watched 

Both MC are OP but overlord is dark themed and has a villainous protagonist while Tensei shitara Slime Datta Ken is more heroic. 

Both anime has the main character transferred to another world as a non-human creature, and become the ruler of a kingdom.  

If Rimuru is the paragon god like protagonist of the Isekai world. The Momonga/Ainz is the renegade 

Similarities: -They both have an overpowered MC -Both have city building elements -Both MC's came from 'our world' -Both have/acquire loyal servants Differences: -Overlord is more 'brutal', unlike Tensei which is silly -Ains/Momonga lost his human emotions and aims to benefit only Nazarick -Rimuru (MC of Tensei) has not lost his human emotions and wants only peace That being said if you don't mind these conditions I recommend you both of these shows from the bottom of my heart 

People do recommend Overlord with this one, but there aren't much similarities. Overlord has a great character and an amazing story. The character is not just OP, he is truly aware of his powers and is willing to use them properly, while "That Time I Got Reincarnated as a Slime" features, well, a slime. The start is very promising and shows a simple Japanese office clerk. I thought, as he is in his middle 30s, he would be a compelling protagonist for this anime. Alas, he truly embraces his "slimeliness" from the 1st episode and behaves in a childish friendly way throughout the story. While the overall "cuteness" might be interesting and funny, this anime is nothing like Overlord. Consider a 5 year old, blessed with enormous powers and either not realising that he has them and not using them or just throwing them around. I have no idea how a middle-aged man would just behave like a child, but here you go. Boring. read more 

Slime and Overlord are both Isekai anime, they both have short seasons (Slime Season two airing Winter 2021) The main characters Momonga (Overlord) and Rimuru Tempest (Slime) are both extremely overpowered and fun to watch.  

while both anime have monsters as main characters they take a similar approach to this isekai patern while being overpowerd they tend to always be careful and have as a goal to dominate the world (overlord) or create their own country and have fun (slime isekai) 

Overpowered/Strong MC in both Both Isekai anime Both MCs do kinda the same things I really enjoy both and think that they are very similiar  

a well written isekai with a protagonist that has a goal and a vision for the world he was reborn in. 

The mcs are pretty similar in power capacities, but slime dude's a bit more of a GOOD guy (a quality ainz is slowly losing) 

Both have very distinct yet very similar plots. On both you have an op MC that has a harem for himself but is completely okay with that. You can also see the reality of monsters in fantasy worlds, which is the case of Rimuru and Ainz. 

Both stories star nonhuman isekai protagonists who are more powerful than most beings they encounter. These shows have great world-building, and large casts of quirky characters. A good distribution of comedy and drama elements keep these stories entertaining through and through. 

They both are isekai's with the MC being,well ''Isekai-ed'' into a new world,into the run of the mil weak RPG monster bodies(being a isekai, they are far from weak). They both have pretty good to excellent world building. They also revolve around their follow monsters, over coming problems almost completely effort less and with both style and amusement. Btw, this is my first MAL recommendation,if i did a good job and you would like me to make more on a certain topic,genre, ect, please let me know. 

>Both main characters is op >Both Reborn in a fantasy world >MC of both animes are non-human  

This series has something in common where the two main characters are kings or leaders in their territories, both characters also have very strong and loyal subordinates. 

Themes of conquering, world takeover, and colonizing 

Both being Isekais. The main character in each of these Animes is set to create their "kingdoms" and to try and either make peace with the current civilizations or dominate them. Each of these characters is extremely powerful in the world that they are born in, with amazing powers and abilities allowing them to do extraordinary things.  

Both power fantasies, the only difference is that in overlord the mc starts being a bad guy right away, while slime has the mc be a good guy at the start 

bouth are isekai over powered main character who is from other world and is non-human with non-human army it's like taking over world and making it better place 

Isekai (from a middle aged man) OP MC Building a small city Protecting natives in that area 

If you're looking for animes with an overpowered protagonists who can even rule their world then these are right up your alley. There's a similar world building where they sometimes go to war with other nations which shouldn't even be called a war because they end up in a massacre by only the main protagonists. Animation is also astonishing so they are both worth watching. The story isn't bad either.  

Both protagonists build their kingdom for their goal. Finding people from Japan 

Similar themes adapting a cheerful slime starting with nothing building a new life in a new world vs an evil empire with top tier allies, items and kingdom to a new world as an Isekai. 

MC tries to build a nation from nothing and both are primarily made of monsters I would say that overlord has better humor and story but doesnt have nearly as good power system both are in core similar but one is on good side and the other on bad. 

Both are Isekai, both have strong subordinates, both all subordinates consider him a great genius, both seek to build a peaceful country. 

OVER-POWERED protagonists which are Demon lord's and have some trustanworthy servent's by their side . One is reincarnated as a slime and another one is locked inside a game which he used to play . 

Both have op main characters who formed a nation and seeking knowledge Both have followers that consider the main character the most powerful Both have a game like world setting with magic and rpg elements Both can be ruthless and pure evil at times 

Both have overpowered main characters that lead a group of strong subordinates and try to expand the influence of their kingdom. In Overlord the fantasy world is in a game and in the other it is just a fantasy isekai world so there are a lot of similarities between the two.  

both good isekai with op mc 

Both stories present the Main Character getting transported to a parallel world where they become overpowered rulers, with their territory and followers. 

Isekai Anime where they are reincarnated as Monster and are Demon Lords but it they ain't no Harem BS. Just some good old Demon Lord Shit. 

- very op main character - put into a different world - very loyal cast - video game like setting 

Both overlord and tensura slime have op main characters. There both have intricate world building and side characters are all equally built up along with the main characters 

- main character is stucked in different (fantasy) world - exploring different world - building own empire - OP (and a little bit confused) main character - funny moments - main character gain more power and influence - various nonhuman races and characters 

The Isekai Genre has become very copy and pasted these days and 'Kumo Desu ga, Nani ka?' is Blatently cloning 'Tensei shitara Slime Datta Ken' ...but it does it well. 

both main characters are monsters. the power system in both animes are very similar. both are extremely enjoyable.  

-MC dies and gets reincarnated as a monster. -MC has the ability to receive power by consuming the defeated Monster. -MC has the memory of his previous life. 

That time I got reincarnated as a: Slime/Spider 

Protagonist reincarnated as a monster in a video game world with fantasy and magic. Video game mechanics like obtaining skills and levelling up. 

Replace the Slime with Spider and there you go, Kumo Desu Ga Nani ka?? I don't wanna call it a complete Rip-off but there are definitely a lot of similarities and so are some differences as well. Give it a go!! 

Both storys tells you about an reincarnated who wakes up in another world having the body of an monster (spider/slime), in a world of fantasy where powers like these on games exist, and the MC isn't really the everyday good guy, although isn't too chaotic If you're looking for a good isekai with a good perspective about the good and the evil, this one may be a good choice. Tell me the truth, u can't stand another good human hero who kills every big bad monster, right? Then let's go, enjoy 

-Both MC got reincarnated as a monster -Bothe has a overpowerd MC -Both 9/10 

Both animes contain are isekai where the mc becomes a monster, starting at a low level and then increases his strength in next to the exact same way through skills etc 

A person gets reincarnated into a spider's body instead of the body of a slime, both of them become extremely powerful, they are basically the same isekai. 

Just imagine Rimuru never left the cave and had to fight for his life since lv1, that's this Anime. Unlike Rimuru that met Veldora and became super powerful right away. Kumoko had to start from rock bottom, even getting used to eating other Animals to survive. She didn't start with pain nullification or immunity to damage, she's just a lowly no name tiny Spider. The anime is not as great as Slime Datta ken but I think the comparison is not fair. If you like comedy and underdog stories then you should watch this and ignore the bad reviews. The CG gets critizised a lot but it's actually not bad because it's only used on the monsters and not on any Anime character. Kumoko is super cute and she has a legendary voice actor. Over all is a fun watch especially if you liked Slime datta ken. 8/10  read more 

The clear similarities include the main character reincarnating in a fantasy world as a monster, first waking up in a cave, learning abilities by defeating cave monsters and possessing a robotic female voice in their head explaining game/world mechanics and new abilities. They take place in strikingly similar fantasy worlds that include dragons and demon lords, as well as magic schools. There are some important distinctions between them though. For example, the main character of Kumo desu ga stays in the cave for a considerable amount of time by herself while other characters have stories completely separately from her, while Rimuru in Slime is out of the cave fairly early and recruits some followers and makes friends. Also in Kumo desu ga, an entire classroom of kids is wiped out and reincarnated into the same world and most of them quickly find each other, unlike Slime in which Rimuru is reincarnated by himself but does find very few other people that are also from his world along his journey. Both are mostly focused on light-hearted fantasy comedy with energetic and charismatic main characters that steadily evolve and become more and more powerful.  read more 

Both characters start off as monsters and they both have a gradual growth of power over their series.  

Both main character are ressussited in a fantasy world whith skills points too learn capacities. Both are funny but they can be serious we its need. Both are overpowered. 

Both anime start slow and generic but get much better after a few episodes. 

Isekai genre anime with reincarnation in monster form (Slime on one side and Spider on the other) Level up system involve. Wtf moments shared between them due to the fact of monster - monster interactions or monster- other race interactions.  

Both Story are based on Isekai world.Both MC's got op by increasing levels and getting skills from the start.They got reincarnated as a lowly being but got strong like a god of the world through out the series.If you like One you are sure to like the other one. 

Both these anime are isekai with the mc being a non-human creature who treats the world like a game. They also give off a similar vibe with the mc exploring to earn new skills to defeat bigger monsters.  

Well,,both are isekaid animes though the story plot are different but i highly recommend "kumo desu ga,nani ka?" if you watched "Tensei Shitara Slime Datta Ken"....not gonna lie "kumo desu ga,nani ka?" is quite underrated and have low ratings but it deserves a lot more rating and popularity...from my personal view,the animation is quite good and the plot of the story was worthwhile too.i can say that your time is not gonna go to waste if you liked "Tensei shitara slime Datta Ken" 

The only similarities between them are both mc are isekai-ed and born in a cave/dungeon. That's all. In term of genre and actual plot, Kumo Desu Ga has better storyline and more fleshed out characters with tons of plot twist.  

If you like isekai both of these are pretty good. Nothing serious, they're kinda just fun shows to watch. 

Slime and Spider are quite similar, in the obvious way that they were reincarnated as monsters, with a much higher power ceiling than any human. Slime is more focused on comedy and adventure for the most part, rather than the constant fighting for survival that Kumoko goes through. Slime has the benefit of no CGI paralysis demons, though. 

Most interesting part about both of anime is that both of mc is born as a low class monster and thrive their way towards the way of op 

jika kamu suka dengan anime "Tensei shitara Slime Datta Ken" saya sarankan juga untuk menonton "Kumo Desu ga , Nani ka?" dikarenakan jalan cerita yang hampir sama,sifat overpower yang menonjol,apalagi komedi yang di sajikan juga bagi saya menarik dan hampir sama! translate google: if you like the anime "Tensei shitara Slime Datta Ken" I also recommend watching "Kumo Desu ga, Nani ka?" because the storyline is almost the same, the overpowered nature stands out, especially the comedy that is presented to me is also interesting and almost the same! japan tarnslate: アニメ「転生したらスライムダッタケン」がお好きなら、「くもですが、なにか？」もおすすめです。ストーリーがほぼ同じなので、圧倒的な性質が際立っており、特に私に提示されるコメディも面白くてほぼ同じです！ 

both the animes,the MC is goated.... -both have many unique skills -both are demon lords -both keep u engaged for a long time in the fun  

Similar world building, and protagonist. Plot widens after some episodes, both have light novel source. 

So I'm a Spider, So What? and That Time I Got Reincarnated as a Slime is very similar, started out with MCs dying and being reincarnated into a fantasy world as the weakest monster in the world. They have to fight their way hard in order to survive. They consume their enemy in order to get stronger, eventually, becoming the strongest monster in the world. Both anime are extremely similar to each other, if you like That Time I Got Reincarnated as a Slime you will like So I'm a Spider, So What? and vice versa  

The protagonist is reincarnated as a seemingly weak monster and the progression of them discovering/gaining skills in a game-like fashion. Worldbuilding in "So I'm a Spider, So What?" in the initial season is much more limited compared to "That Time I Got Reincarnated as a Slime" because the protagonist stays in a dungeon for most of the season but they are both equally enjoyable 

The two are isikais that features a person getting reincarnated into a small enemy, Whom both were spawned in a cave environment. They also end up in a magic fantasy world with demons and stuff 

Both anime is about isekai reincarnation, into a monster form. Both characters are interesting and humorous. There is a moderate amount of action in both shows, though Kumo Desu Ga has more blood content. Both plots, while somewhat similar, also have their own differences, which makes both anime uniquely interesting and feel fresh to the watcher. The animation is very similar to each other.  

Both Slime Tensei and Tsuki ga Michibiku are pretty generic and average isekai with similarities: * Main characters are very overpowered * Main character allies a dragon * Main character helps demi-humans (orcs) build up their lives Tsuki ga Michibiku is just a worse Slime Tensei + Slime Tensei has much cuter girls 

Similarities: - Both MC are OP. - Both MC are trying to build a town where everyone can live a happy life. - Both MC can make a contract with other characters to serve him and given them a name make them stronger.  

-overpowered mc -town building 

Both are isakei where the main character builds their own city and is majorly OP. 

"Moonlit fantasy" is literally just a worse version of "That Time I Got Reincarnated as a Slime". In both the MC is reincarnated to another world with godlike powers, both have super OP followers that would do anything for them (and do most of the fighting), both have a focus around building and maintaining a "monster city". etc, etc. Slime is better in probably every regard but moonlit fantasy isn't unwatchable, it's about as good as most other generic isekais getting released.  

They are both isekais about forming nations made from coalitions of monsters. Tensei slime is a lot more slower paced and focuses on world building, whereas TsukiMichi jumps right into it. 

Includes (but not limited to): - Isekai - OP MC - Sid Meier's Civilization-like plot - slight race war between humans and monsters (some may call this racism) 

This is for you if you like overpowered OP MCs that build their own community of and for non-humans after getting isekaid. Building the community and experimenting with skills plays a relatively big role in both. Both MC's are admired for their strength and gain loyal followers as well a harem of pretty girls.  

Tensei Shitara Slime Datta Ken and Tsuki ga Michibiku Isekai Douchuu share a remarkably similar plot. In both anime, the protagonists are reincarnated into a fantasy world with formidable powers, leading to the creation of their own cities. The story revolves around their evolution and growth within this new setting. While personally favoring Tensei Shitara Slime Datta Ken, both series delve into this development aspect and bear striking similarities.  

In both anime, the main character indirectly builds a community in which he is surrounded by OP characters, like him, who see him as a leader. 

- they're both enjoyable and fun Isekai, with lots of comedy - the main characters are ridiculously over-powered and only get stronger - their followers are ridiculously over-powered - there are very few threats that would affect the OP characters - both feature world exploring, while the MC is trying to adjust to his new life - they both feature town-building, their inhabitants are made up of different monsters - both try to establish business such as trading with other countries - the main characters are level headed, kind, and mega virgins 

Both are isekai anime with an overpowered MC and cool battle scenes. Also, both try to establish a new kingdom/country in the new world.  

Both anime are Isekai genre with a similar plotline. Slime focuses more on plot/world-building and fighting while Tuski Ga Michibiku is a more comedic twist on self aware isekai'd MC who tries to live a normal life but develops a similar relationship as in slime with an OP dragon. 

Same premise: Japanese guy gets isekai'd, is secretly super OP and has to hold back his immense powers from others, turns monsters into his worshippers, creates villages that he tries to advance using other world knowledge. 

Both are very similar, the MCs are transported into a fantasy world after dying in their previous one. They have strong superhuman powers and establish their own society/group as Monarchs/Leaders. The only different thing is that the MCs are different in appearance. 

Both are reincarnated as an overpowered character and on a journey to build their own nation.. 

provides the viewers with very wholesome comedy and world-building , centered around an OP isekai'd MC who meets different species of characters throughout his journey who then become the foundation of the nation built . The main highlight between these two MCs is that they both feel empathy towards others as they also suffered the same in the real world , which opens up more about the MC's background. (TLDR: if you like comedic along with wholesome-paced isekais and see the development of an amazing world / characters , these two are for you) 

MC's are OP and both will build a nation where human and mionsters can co-exist. Mc's are very timid and don't want to stand out but eventually they are god-class entities. Isekai anime with character buildup is entangled with comedy and serious scenes both. In both anime, There is a involvement with dragons. 

1) The main character is overpowered as heck and people not in his group underestimate his true power 2) Both main characters build their own community in which they rule over 3) Everyone who is around him is yes man. If you liked how the main character could rarely do wrong in the eyes of his followers, this is also a good watch. 4) Both of these animes have side characters that have great energy and it's funny to watch them all bounce off of each other. As well as off of the main character's  

Both feature a male character being transported into a foreign world. Where it gains a fellowship among others and builds a nation from nothing. In his country, the male character receives a god-like status. There is some difference between the two anime: For slime, the MC died while for Moonlit Fantasy the MC gets transported. For slime, the MC started out very weak, and have to slowly gain its power thru struggling. While for Moonlit Fantasy, the MC started out quite powerful.  

Both series have a similar start and both remember more the way to play an MMORPG game where the character has to evolve to be stronger when uses abilities and arms. The protagonists are misunderstood! 

Both are Isakai adaptions of similar quality. The main character in both is interesting, or at the very least unique. Both are shaped by the world they interact with. 

Another Isekai with a protagonist that isn't necessarily a 'good guy'. Interesting spin on the iseakai trope 

These two series are likely similar. Especially on the Isekai genre. Although Tate no Yuusha's main character start with a despair circumstance, but in the end he got a powerful ability. Same with Tensei Slime Main Character, in the beginning, he only just a weak slime. But the he got an overpower ability. I really recommend these anime, because they really made me enjoy their story. 

both have the same story plot where guy finds himself in another world and both involved having to start from scratch in order to be somebody and to be powerful, however in Tensei, the guy is a 30 year old man who died and was reborn as a single cell organism, while in Tate, the guy is a coll student wh started as a low level hero who become a zero and now has turned into an anti hero.  

The MC is summoned to another world where he is the weakest and grows stronger by absorbing powers off other things. 

Both series contribute innovative ideas to the extensive genre of the isekai, with simple arguments but which more than manage to immerse the viewer in the plot, something that is not usually easy to do. 

Kind of the same concept, and harem vibes and their world is also kind of similar to each other 

both an isekai and both are battle animes. These two are probably my favorite isekais and they both have interesting characters that it will make you mad to wait for a new season 

Both main characters are summoned/reincarnated in the other world They have a similar vibe They have similar art If you liked one, you will like the other one too I LOVED both of them so much that I decided to read both mangas 

isekai anime is great, both have many uniques power 

Both are Isekai animes so both teleport the MC to another world both seem pretty similar about the new worlds, but the MC'S have different abilities and have different backstories.  

Both are isekai with likeable main characters that build rapport in the new world with good deeds. Also, both worlds have diverse species that the MC’s don’t discriminate against.  

Similar world, also both main characters are sent to another world. 

Both of these are isekai animes where both have OP protagonists. But one character steadily becomes powerful while the other one becomes powerful after a lot of hard practicing. Both animes show the ups and downs that the main characters face when the animes progresse. 

Both are isekai animes where are older main character is killed them they reincarnation into a fantasy like land, where they still remember there old life. In both main Characters start a new life in this fantasy land with a new body, new name and new world.  

Both are isekai with very high production value. Excellent voice casting, art style, direction, etc. Both feature a main character being reincarnated from our modern world into a fantasy world full of monsters and magic. Have fun! 

If you like and enjoy Isekai. Go give this one a try. Rudy might not be the best MC so far in the Isekai genre but he's the one of his kind for sure. Rimuru, on the other hand, is one of the best Isekai protagonists out there. The world-building is really well done in both shows. 

In both animes the main character failed to do anything in life and promises redemption in the next one, both main characters are kinda overpowered and easily learn the ways of the new world they got into 

Both are isekai anime, both have OP Protagonists with action, humor, and magic(now don't be like "it's not a human its a slime" but trust me, if you are that kind of a person still you will like it, cuz I was that type before I watched this), season 2 is ongoing at the time I'm recommending this (march 2021), has an interesting storyline, great detail to the artwork and animations. Actually its better than Mushoku Tensei in my personal opinion. Try it out, 9.5/10 

Two are considered alike in terms of ideas which these shows are able to offer. Wishing for a second chance and what could happen if that desire came true. Living as an another person to an another world to fulfill fresh opurtunities, bringing motivation to anyone who will watch it. So why not give it a try? See for yourself and be inspired to what it has to offer. 

>IsekaI >Both are about magic. >Both are op by his age >Both MC have their old memories from the previous world. >Both have comedy HIGHLY RECOMMENDED 

They are both of reancarnetion isekai, characters are so much and interesting (But Slime has more character.) main characters are both of going from retionel ways also Mushoku Tensei is shorter so feel boring is little bit hard. (I love Mushoku more 😁) 

Similar in following cases 1.Reincarnation 2.Magical World 3.New life feel 

That Time I Got Reincarnated as a Slime, Mushoku Tensei, and Re:Zero are my top 3 isekai. 

They’re both isekai and have been reincarnated into different bodies after dying. They’re both OP and have a questionable way of dealing with different situations. (There’s also the manga So im a spider, so what? That id recommend as its really similar to that time i got reincarnated as a slime, they’re both monsters, They’ve both been isekai’d they have skills that they can use at will and are both OP) 

Both are some of the best Isekai to this date, not only do they have great World Building but they got good Animations and Action aswell. 

The story has a similar premise (protagonist dies and transported to another world). However, Mushoku Tensei is so much more engaging, as you watch Rudeus' growth over YEARS and you become helplessly more invested as you continue to watch each episode. The pacing of the story and each character's depth, development, and role is placed perfectly in the storyline. Each character isnt just randomly placed in the story, but rather shows how their relationship with each other help Rudeus grow to overcome his weaknesses. And, the world building as the story progresses is sequenced and detailed so perfectly. You'll find yourself fully immersed in depth of this world, which is on par with The Hobbit/Lord of the Rings (but you'll also have to read the light novel). Unlike Rimuru's power aquisition from the get go and complete dominance over his foes, Mushoku Tensei's protagonist (Rudeus) reincarnated character and power development from infant to adulthood, isn't over the top. His power doesnt dominate over everyone. He still carries his mental/emotional weaknesses and insecurities from his 34 yo self in his previous life. And also his weaknesses in his new world (unable to do voiceless healing magic, incapable of producing battle aura, and making numerous mistakes in battle due to his inexperience/insecurities). This is the first anime that inspired me to read the light novel from which it was adapted. Although the anime adaptation (mainly season 1) is very well done, ie animation/music/director, you will still need to read the LN for full immersion. And, as you read the light novel, you'll realize how much more depth the world and its' characters actually have. Including the side characters (Sara, Nina Farrion, Isolte, etc) and how their relationship affects Rudeus and his family. What an AMAZING ride! Hands down the BEST isekai i've ever come across so far. read more 

OK, this is the total opposite of Mushoku Tensei, but is exactly like mushoku tensei, if you know what I mean. Can't really explain it, nor with examlples so trust me with a grain of salt. :D 

Both feature a main character who dies after an unfortunate accident and they get reincarnated into a world with magic with their previous memory intact. Both have to start at a very weak state and have to slowly grow and learn into their much more powerful state. In my opinion, these two anime are some of the best anime the isekai genre can offer. I will strongly recommend you to watch both if you enjoy one of them 

Though these anime are different in many ways, they are also very similar: - Both anime take place in a medieval setting in essentially a different world. - While one MC gets reincarnated in another world and the other one just enters through a game, both MCs start out as a very innocent and naive character who quickly becomes powerful. - Both MCs got their OP defenses by not wanted to feel pain and gain additional resistances and attacks through experiences with their enemies. 

There are the same power evolution system, the main character will unlock new abilities until become cheat. 

By their main character, support characters, story, power up almost everything are similar among this two animes. I strongly suggest to watch it. 

- The MC gains new skills by devouring their enemies. - Rather powerless MC becomes extremely strong. - Both MC become leaders (Rimuru of a town and the creatures in it, Maple of a guid, although there is an obvious difference in their leadership skills) - Also isekai! Though in the second one it's a virtual world - Both MCs have either a lot of fans or a lot of followers 

Both are animes where they start off with the MC's getting OP without really noticing it. They have the same wave length in terms of comedy and overall feels ig? Both feel chill but have good action at the same time and the story line doesnt feel left out either in both of these animes.  

1. both MCs gain their powers by eating 2. both MCs are op 3. the MCs can almost not be hurt and one character sounds like rimuru 

If you loved Slime give this one a try for sure. -It has the same "positive" atmosphere of conquering a new world. -Maple is really likeable and over powered due to her not understanding how the game works and her insane luck (and defense). -They even have similar abilities, Devour. -I pick this one over Shield hero because shield hero is more of a "serious" Anime compared to Slime and Bofuri, but Shield Hero is a must watch also. Just make sure you skip the intro it basically spoils everything that happens in the Anime and it's baffling... 

Both are iskeai where the main character quickly farms xp and becomes overpowered. 

Similar mechanics, an isekai/fantasy theme, fun characters with the main character gaining more overpowered abilities in similar ways. Bofuri had characters that were more enjoyable, but Slime has much more plot and world development. 

Both MC (Maple and Rimuru): Started very weak and slowly gain their power via eating. Both have the ability to take little to no damage. Both become so ridiculously overpowered that they are almost unbeatable.  

Both of these amusing shounen series feature someone with modern-day knowledge thrust into a new world where they have to start over. One ends up in a magical world with technology reminiscent of the middle ages, while the other winds up in the distant future where humanity has reverted back to the stone age. 

Main Character gets "transported" to a world that is not quite like the one they came from. Sets out to rebuild/build a civilization from scratch. Finds a village that ends op helping to kick start civilization. 

The Anime Known as "That Time I Was Reincarnated As a Slime," is very similar to doctor stone in very similar ways. Before I go into comparing the two titles, I will contrast the two. Doctor stone is a show of Science, following the main character, Senku, on his journey that goes thousands of years into the future after he turns to stone, as well as the rest of the world. Suprisingly, he is the first one to wake up from his slumber, because of scientific reasoning. The main character of this show is smart, not strong. Slime is an isekai that follows rimuru and tells a tale where he dies as satoru, this 37 year old man that is still a virgin. This story is different for many reasons. One of those many reasons is that rimuru is not as developed with any shifting or conflicting thoughts as senku may have. Instead, his actions in the show are resulted as his death in the real world. This show Is what you would call less rolled out, or elaborate than Doctor Stone. These anime are both similar because the common interests of the main characters are to start civilization up. You could say that Doctor Stone is also somewhat of an isekai. Whether or not, that is my opinion. These two stories have characters that sort of win over different characters with their own tactics, rather than fighting them or the enemy directly. This is used to build up their numbers and increase their strength as a society as the story progresses. The reason you should watch Slime, is because this has a very common interest in doctor stone. Now depending on what you like, a fast paced story or a slow one, that will decide whether this is for you or not. This story is slow, but It does have some truths behind it that are yet to be explained. read more 

Worldbuilding, Society, Village, Medieval times, Wars, Nature, Progressive, Acquiring & Fusing new things, Main characters are against separatists 

-Both About Nation Building -Both MCs have more knoledge than others that make them OP -Both Animes have a confirmed 2nd Season where they hold a war (21/11/2020) 

Both have the MC start from nothing to build a new society. With Senku, he is rebuilding society with the power of science. With Rimuru, he is rebuilding an old village that used to be run by goblins and making more. Both are great in the comedy aspect and have an OP mc in their own ways (Senku with his brains, Rimuru with his slime copy ability) 

both have incredible world building 

Civilization building  

Both reborn in a new world both become overpowered both gain the power of the monsters they eat both eat monsters both started off as weaklings 

Both reborn in a new world both become incredibly op both gain the power of the monsters they eat both eat monsters both started off as weaklings Arifureta has more of a harem than Tensei but there is the harem element in both. 

Both are very simialar. Both MC are stupidly overpowered. In both the female charcathers fall for the MC and for good reason. 

The main characters of these two anime had a great evolution. At first they were weak, but in the end they were the strongest. If you like to watch the main character develop, this anime is perfect too. The two animes are also similar when it comes to the secondary characters too. Both main characters have strong companions and their number is increasing. 

Isekai ✔ Harem ✔ Gains the power of the enemies they defeated ✔ 

Both are isekai main characters and begin in scratch upgrading their skils and more. 

Both reborn in a new world both become incredibly op both gain the power of the monsters they eat both eat monsters both started off as weaklings Overall both have similar vibe . 

Both are isekais and the magic and abilities of characters were of similar genre.  

Both have Isekai protagonists that transmigrate to a fantasy land and then proceed to take their time establishing themselves in the world. The slow burn of our protagonists becoming more renown, while gaining skills and connections, has a very similar feel between both shows. 

Similar vibes. I would classify them as the same 'type' of isekai. The MC travels to another world and, using his/her skills from our world, improves or better the new world. Both MCs are kind of know-it-all characters and interestingly, both also have blue hair. They both are a bit too perfect and can do nothing wrong, I guess, but Rimuru (Slime) is also definitely OP.  

If you liked Reincarnated Slime's way of building a world narrative slowly over time, Ascendance of a Bookworm does this on a smaller scale but still feels just as rewarding when things are done. Doesn't have much action and is a lot more slice of life isekai, but makes up for it by keeping the idea of the Main character's past life a more central plot point. 

- Isekai - Both MCs are seen as weak until proven otherwise - Both Mcs are focusing on helping the society around them (and not only) evolve (Myne inventing things and creating her own shop, Rimuru creating a new nation of monsters that unifies different species) - Light themed anime with a friendly atmosphere (well... mostly) 

Ascendance of a Bookworm is an amazing anime about a girl who after being reincarnated into a world filled with a classist society, poverty, magic and most importantly: no books?! Myne's passion for reading is stifled as there are no books available to the commoners, Myne must overcome her mysterious sickness, with friends and family helping her along the way. Her goal? To read books! Honzuki no Gekokujou is similar to Tensei Shitara Slime Datta Ken because both animes show strong leads with determination to change the world around them. Both animes also have beautiful scenery and based in a town.  

Both started with MC being in a very weak state and having to work hard. Both have knowledge of their previous life and use that knowledge to make the life of people around them better. The world-building vibe for both anime is quite similar.  

If you appreciate that Slime breaks the isekai norm by focusing more on politics, society, and development than on combat or slice-of-life, Ascendance of a Bookworm takes it further and is entirely focused on politics, society, development, and economics. Both series are about the protagonist's rise in influence, though while that influence is won through battle quickly and easily in slime, the protagonist of Ascendance of a Bookworm struggles immensely for every inch of progress. 

Both series are isekai's that have the protagonist building a civilization from the ground up. Log Horizon is a true transported to a video game while Slime's world is more a pure fantasy world. They are both animated in a super G rated style. The action is fun, but not long or graphic.  

Both have a protagonist in a fantasy-like world that are responsible for developing and leading their "people". Both are relatively stronger than their opponents but for different reasons. Neither feels overly serious but don't get too far into some of the fantasy cliches. This has better comedy while Log Horizon has better "wow" moments. 

While both the settings are different (trapped in a game vs reincarnated in another world), they have a similar feel to them. Growing and governing a village from scratch (or a nation, in Slime's case), dealing with other nations and people of power, and being a leader for their people. MC's with big hearts and who wish the best for their people. A large cast of characters that continues to grow during the anime, and that you learn to love. Both are very entertaining to watch, and have some exciting action to top it up.  

A isekai anime in the same way. The main character provides similar contributions to the world in which it is located. Our character sets up a community in the same way. 

this anime has quite the good story like those two other animes though in some episodes,you might get bored...i got bored at least but the anime is good if you watch it with patience...i am not saying this is one of the best among the isekai animes but the anime is worthwhile to watch 

Both have the protagonist reincarnate into another fantasy world, where worldbuilding takes part with them in the center. 

Similarities: > Both are Isekai series (characters are sent to another world). > Both main characters are overpowered and deal with "difficult" situations with relative ease. > Both are set in fantasy worlds (swords, magic, monsters etc.). > Both have a very laid-back "fluffy" feel. Story arcs are generally focused on making other peoples lives better. > Both have an English Dub. Differences: > Slime has a more developed story (opinion). > Isekai Smartphone has major Harem elements. > Slime's animation is better (opinion). > Slime is a 25 episode series, Isekai smartphone is 12 (also more likely that slime will get a second season). > Slime is loved and praised, Isekai smartphone is criticized.  

Both involves the same individuals who died and finds themselves in an alternate universe where the become someone who is powerful.  

Both are fluffy bubblegum isekai fantasy with OP nice guy protagonist. The way they do "diplomacy" and "politics" is so simplified and it just works out easily that kinda breaks suspension of disbelief. Slime has better story, Smarthphone has harem. 

In both series, the MC is extremely powerful. Another similarity is that both of the MCs are reincarnated in a different world, and we also have a harem in both series. The only major difference is that the MC in "That time I was reincarnated as a slime" was reincarnated as a slime and not as human (like In Another World With My Smartphone)  

Both feature MC that died suddenly and got transferred to a fantasy world. Both MCs gain new skills throughout their journey and slowly become stronger and stronger. Both MCs care about others around them and will protect them at all costs. Both MCs are extremely well respected, which as a result attract girls romantically. 

Offbeat sense of humour Bouncy animation Makes fun of Isekai tropes  

refreshing, isekai and comedy genre. 

Aside from both shows being isekai, they have similar colour palettes and the same light-heated tone and cheerful cast of characters. They have similar styles of humour since both MCs played video games in their past lives and have similar personalities. The magic systems in both are also similar as they both are based on acquiring powerful skills to become stronger.  

I may be a bit biased, but man I love this show, its my favorite show of all time. It is fantastic and has great world building. The reason why I think if you like Konosuba you'll like Tensura is because it has good comedy. It also bring you serious moments and awesome fight scenes with amazing animation and sound design. It starts slow at first but it does pick up and its paced really quickly if you're into that. Season 2 of the series is by far the best part of any series I've ever watched and reason being is it brings out my inner nerd. Season 2 is more on the darker/serious side compared to season 1 but still worth your time! That concludes my recommendation and have a good day :) read more 

They both give the same vibe. Also both main characters in the animes entered a new dimension/world :) both are awesomeee 

Both series feature mid-30's salarymen being reborn in a JRPG-based fantasy world. The MC is gifted with extraordinarily OP cheat skills right off the bat and wields god-like abilities (much to the dismay of the supporting cast). The MC gains a large, ever-increasing number of devout followers (or a straight up harem). The opposition, if any, is easily defeated or subdued while the MC grows more and more powerful. 

Both have same OP character and great Isekai World. 

Both male lead isekai or teleport in another world Both male lead has overpowered Both has harem spice Both has sinilar setting where mc life in oldest time 

Both protagonists are selecting many useful skills for a following adventure. But I would prefer this anime, because here isn't a harem and it goes on more logical.  

Isekai both have OP mains the use of magic  

Both of the main character got reborn as a overpowered being. The main character of Tensei shitara Slime Datta Ken (TenSura) got reborn as a slime, while on the other hand, Kenja no Mago got reborn as a human being. The story of TenSura is taking place in a country, while Kenja no Mago is in a academy/school. If you like isekai anime with overpowered main character, both of these anime will be suitable for you. 

The same isekai plot where it involves character that dies from the real world only to get reincarnated in a fantasy world and becomes someone great........as usual. 

Easy-to-watch Isekai, both are a bit superficial (as usual with Isekai) but involve likeable characters with great powers, willing to fully enjoy their new life. If you want to relax/enjoy a positive anime after watching the Mirai Nikki-type, these two animes are for you ! 

Both main characters gets reincarnated in other world after death and from there on they both use knowledge gained in previous life in their advantage for their upcoming journey  

-Both are isekai/reincarnation animes where MCs are reborn in a fantasy world after their death. -Both have strong MCs whom built a kingdom/village where different species of monsters can take refuge and live happily.  

Both male MCs are transported to another world after dying. They also get some cheat skills/powers making them pretty powerful in what they are doing. The main similarity is town/farm development from scratch, populated with various race from monsters to elves.  

1) Both are reincarnation animes 2) Both have strong main characters, but Farming's isn't as OP as Tensei's. 3) Both have a nice supporting cast where everyone gets along 4) Both have the Main characters become leaders pf a place where monsters/demi humans can take refuge and rest in. So, politicking and diplomacy are common.  

Both have the Isekai'd MC start off normally, but eventually grow in both stature and power over time. The worldbuilding for both is impressive, but TenSura is more focused on conflict and action than Nonbiri Nouka, which is more mellow and tame. Both also have great comedy, and a large cast of characters that eventually join forces with the MC and their kingdoms over time 

They are related to slimes. The MCs of the animes reincarnate into another world. They are immortal in the series.  

Both are about slime, one is about killing slime and one is slime killing everyone else. Both MC started out as very weak but slowly grow into someone overpowered. Both MCs receive a lot of respect from others around them.  

Both mc's lived boring lives until they died and got reincarnated. In this new world they're powerful, and nothing like how they were on earth. 

- slime - another world - strong MC 

- Slimes. A lot of them. - Isekai - Slice of life feeling for both of them, though in That Time I Got Reincarnated as a Slime not as much - MC has to fight monsters, though only occasionally - Mc is constantly trying to evolve when it comes to their shop/town  

both have similar vibes when watching. kami-tachi leans more towards the wholesome-adventure SoL side, while, tensei is more shounen oriented with greater acion. Both animes have OP MC's who get isakai-ed. If you enjoyed kami-tachi, you may possibly like tensei; there are times where tensai will have a similar relaxed vibe that kami-tachi has throught. 

If you enjoyed the way that 'No Game No Life' had intellectual battles of wit, the chances are you will also enjoy watching 'Tensei shitara Slime Datta Ken'. They also both have a comedic element that is on a similar level. 

-both have overpowered protagonists who are teleported to other worlds -have similar feels of comedy -both protagonists have no interest in love but both share their love for...;) -if you enjoy one of these animes you will def enjoy the other 

Both are Isekai, both are great geniuses, both seek to build a peaceful world, both are lords and evil kings, 

is slightly similar. shows mc getting reincarnated mc being really strong and all that. 

Both sound like a terrible idea that makes your skin crawl in anicipation of a dumpsterfire. An Isekai with an Op MC that constaly gets new gadgets and followers? An game reincarnation Isekai were the Harem doesnt just happen incidentaly but is the actual plot? Well. let me say, both of these dont execel at their novel concept, but in execution. And show even the most overused tropes can still be entertaining if done right 

Both MCs unintentionally get a lot of respect and help from others. Both are Iskeai'ed and retain their memory from their previous life and use that memory to help them achieve their goal.  

If you liked the isekai elements of Re:Zero and were wondering what someone in a similar position as Subaru would do with his knowledge from Earth, Slime is a great show!  

Re:Zero and Slime are two sides of the same genre. Re:Zero does a dark and serious isekai to a tee, whereas Slime is the lighthearted power fantasy isekai that isn't so cookie cutter to make you snooze. In the isekai genre these two do it the best. 

2 MC that are very smart and good at building society by improving it's economy and political stability, so I recommend go watch and check it out. 

Both has anime has world building increasing their reputation abilities and also governing the land. Tensura has more fights and skills than realistic hero but both are very good  

Both shows are based on video game-like capabilities. Badass & OP protagonist. A more complex story than it seems. 

both mc's are overpowered af 

Both are Isekai, Both are about an incredibly strong man, Both story are set in a fantasy world, Both main character can steal abilities, and quickly become very powerful in their own right, 

Both MCs died and reincarnated as non-human. Both MCs are forced to kill other creatures in order to survive and get stronger. Both also feature some kind of announcer that only the MC can hear. 

feel good isekai with a feel good MC that mostly strives to help others. cute characters and fun personalities 

Both Rimuru and Yuna is quite similar: Both got isekai’ed into a foreign world Both use their knowledge from their previous world to help others around them Both end up earning a lot of respect from others.  

>Both MC get transported to another world >Both show's have great character >Both have mix of funny moments and intense moments  

There are some similarities, for example, a game-type world, cool enemies, and fast growth of the protagonist. Even though Dungeon ni Deai is kind of a romance, it's still of the genre of Adventure. 

That time I got reincarnated as a smile has the same isekai baseline, but profits from far better-exected animation and a more intense storyline. If you liked "Hachi-nan tte, Sore wa Nai deshou!" I am sure you would enjoy the little slimes story at least a bit. It takes itself and it`s new world more serious and also doesn`t lose the humor on the way. -more Monsters -fewer Politics 

-It follows our main character transporting into another world. Trying what they can to survive but with overpowered power and opposite personalities. 

-MC dies and gets reincarnated as a monster. -MC has the ability to receive power by consuming the defeated Monster. -MC has the memory of his previous life. 

Both animes have a very overpowered main character. Both awesome to watch for Isekai Fans. They both lead an "army". But in Tensei shitara.. the Main character is more nice to others then Ainz is. I realy love both. So check them out :3 

Both are isekai's with OP MC'S Both have a "Demon Lord" Theme common in them Both focus on building a team of powerful people (7 deadly sins and Rimuru's entourage) In both the anime, all side characters are not at max power at first but become stronger and stronger till they reach their full strength. The only difference is that in 7 deadly sins, there is no world building involved. 

We have an overpowered protagonist who is slowly building up his army. The world marvels at the immensity of what he is able to do, and of course, they are both reincarnated, possessing knowledge of this world and taking it to the new world. The series develops in a surprising way, we have followers loyal to the extreme, following every command of the protagonist, which generates many funny situations. In the case of Eminence of Shadow, the protagonist tries to hide his real personality and power at all costs, which makes his outer persona an extremely weak young man. This leads to many funny situations. In short, he is the most powerful character in the story, every time he enters the scene it is just to make the point. It is fun to see such a powerful and sadistic character, because he is not really a hero, but an anti-hero, but he is not a villain. read more 

Both involving a main protagonists travailing into a Fantasy world. 

It's very similar in terms of how each get stronger as it goes on and both have that Isekai vibe, I know anyone who watches this will absolutely love it! 

Somewhat similar animes with the main similarity being world development. If you are a fan of Overlord you will most likely be a fan of Slime. In both animes the main character is overpowered and that is used as a plot device for world building and domination. The main difference is that Overlord is somewhat more "grim".
