Main Protagonist is an overpowered Psychic and is of similar character. While the vibe is different, the settings come close to each other. Both are students and have interesting people around the Protagonist.

Although Saiki is an esper and Sakamoto is not, both characters turned out to be surrounded by people who becomes enchanted by their abilities in school and eventually into their personal life.

These are both light hearted comedic shows with similar senses of humour, neither show takes itself too seriously. Both MC's are ridiculously over powered, and decide to focus on the downsides of having such power.

The main characters in both animes are so overpowered, but they hide their powers. Funny daily life stories. The main heroins also like the main characters who don't care at all.

I find them rather similar with school life setting and comedy. While Saiki has supernatural power and Handa-kun is a well-regarded school idol and prodigy calligrapher, all they wanted just a normal/quiet life but often hilarity ensues.

i would say if you really enjoy the comedy of one of these anime, then you will definitely enjoy the other one as well they have the same kinda vibe to the main characters (uramichi and saiki)- very tired and annoyed from everything and everyone around

In a certain sense, Saiki can be considered as the "male" version of Gekkan Shoujo Nozaki-kun, since while Nozaki parodies the shoujo's tropes, setting and characters, Saiki does the same, only with works for the shonen audience. The only difference is that Nozaki is strongly focused on romance and sometimes are sentimental, while Saiki always remains a gag comedy with an unceasing parody and humor.

Both are comedies that are actually enjoyable and are not filled with second-hand embarrassment. The focus is more on the characters than on a relevant plot. Although not on the same level as Asobi Asobase, Sakiki does have its fair share of screaming and hilarious faces to go along with the anime. In general, their plots aren't alike but they have the same vibe.

The obvious comparison between these shows is the main characters... Both psychics with similar personalities (bar their intelligence) being forced into similar wacky situations. Both shows have a very similar style of humour and plot-layout as well. The main difference between these shows is the intent. Saiki is a more fast paced, skit based show intent on being as entertaining as possible whereas Hana starts off similar to that but quickly converts into a fairly heartfelt comedy with some real meaning behind it.

Similar type of comedy shorts type feel, concerning a character and how hes not what he seems. Although more alike in 'vibes' i guess than plot, as Saiki Kusuo is definitely more extensive with a larger cast and somewhat of character development, but both shows are baseline feelgood comedies and I think if you enjoyed the comdey style in one youd like the other.

I instantly thought Beelzebub when I started watching Saiki. They are about high schoolers with unique attributes. They are both slap stick comedies with no deep plot and have episodes with stand alone plots.

somehow the exact same type of cast/characters, writing and comedy with the exact opposite plot/premise - both shows will make you laugh way more than you expect (comedy gold mines) - iruma and saiki are the exact opposites of each other personality wise but they both live with the goal of wishing to be seen as normal and blend in (even though their roles make it very unlikely) - both main characters end up having like a fanclub's worth of friends without desiring it and it's great

High-school comedies, quite parodic, with "alien" characters. Psi seems to have Cromartie references, such as Nindou and the guy twitching his hair... So far, I prefer Cromartie. It's definitely more manly too.

Why did I recommend this when Saiki is a genius and Yoshiko is an idiot. Because everyone besides Saiki is completely clueless. Yoshiko's childhood friend is somehow similar to Saiki. Both anime have minimalistic art and many colors. Both are fun to watch.

short, quick moving gag jokes. sarcastic character who acts tough/emotionless actually cares for his friends a lot more than he lets on. neither show takes itself too seriously. Senyuu has more of a plot building up in the background, while Saiki is solely comedic.

If Hiroshi Kamiya ranting about the absurdities and logical inconsequences of Japanese society and humanity in general sounds like your idea of fun, both series are right up your alley. The protagonist also plays a similar role in both series, being a reluctant helper for the bunch of dysfunctional beings that in turn make him find his human side.

-Main characters talk too much (probably need to pause a lot to read the whole thing if you don't speak Japanese). -Both main characters are cool dudes that can do everything and anything, basically. -A LOT of characters in both stories but you'll like all or most of them (charismatic chatacters). -Funny shows; somehow the humor feels similar.

- Deadpan, level-headed protagonist. - So very punny. - Fast paced gag humour. - Colourful supporting cast with their own amusing and troublesome quirks (troublesome for the protagonist at least). The setting is very different but the pacing and style of joke telling is pretty similar. Japanese knowledge is helpful because subbed puns can be hit or miss.

Both basically are about high school daily life with over the top comedy scenes. In Saiki Kusuo, mc is using his psychic power to solve any problem he is facing, while in Chio chan, mc is using her gaming knowledge to solve any problem she is facing.

School setting with really crazy comedy and large cast of characters. There are some similiar archtypes (for example, hot-blooded class president, delinquent who tries to leave his past behind, etc.).

Both consist of really funny shorts with unexpected and overly dramatic gags. Some of the episodes are philosophical in a sense dealing with people, problems of society and emotions. Both are set in a school environment.

The Disastrous Life of Saiki K has many very similar aspects as Ouran High School Host Club. For starters, they're both comedies with similar senses of humor. They also have episodes which can be watched almost completely independently. There are no long-lasting arcs so you won't need to have watched the whole show to get each episode. If the rewatch value of OHSHC was admirable to you, then you'll find Saiki K to be the same. Overall, both are dumb fun anime which you can rewatch over and over when you're feeling down :)

Both are comedic anime, perfect for getting a good laugh at the end of the day. With each of them having characters with unique and interesting quirks, never a day goes by without some random and stupidly dumb events occurring. Grand Blue is probably more age-restricted, as it contains content not suitable for younger children (such as drinking, nudity (censored) and suggestive ideas). However, this anime would definitely not be complete without such idiotic themes. It creates a large part of the plot and sets up the scene for many situations. Saiki Kusuo has some supernatural elements and is a crucial factor in its own right. The  read more

In terms of the comedy, style presented, both go for an in your face style that is quick, loud and entertaining if that is your preference in said comedy. Character interactions are very similar in tone and attitude too but one must keep in mind that this style of comedy is character focus around said events, so basically, liked the character and the pieces will fall into place.

As for Osomatsu-san there is no story as a whole, I think it's important that its recommendation is not just another anime with comedy. For Saiki Kusou is somewhat the same, there is no story outside of comedy to develop. It doesn't switch between comedy and story. It's just for comedy.

There are many things that are similar between the two shows which include: - similar genres (slice of life, comedy, school - the genres are present in similar style as well) - similar characters - to elaborate: Koyuki and Kusuo share the desire to be normal, yet their daily lives are interrupted by the weird people around them.

-Both are comedy anime with likeable characters Even though these series don't have similar stories, they'll both leave you with a smile. So if you are looking for another show like Love is War, then I recommend Disastrous life of Saiki(or vice versa) because of their likeable and sometimes relatable characters. Details: -Both main girls(Teruhashi in "Saiki" and Kaguya in "Love is war") have the goal to make the main character fall in love with them but falls for them instead -The main character in both series (Kaguya and the president /Saiki) are both gifted in some way

In Saiki K. there's the typical anime characters- delinquent, pretty girl, super energetic class rep, the stereotypical dumb guy, etc..

Both shows, Saiki Kusuo and Nanbaka, have the similar factor of heavy comedy in the earlier episodes. Although Nanbaka strays away from comedy and focuses more on serious issues in the latter portion, Saiki Kusuo holds true to the comedic aspect and carries through 'till the end. If you've seen Nanbaka and enjoy the wit and humor of the characters, Saiki Kusuo no Psi-nan is definitely something you should consider.

They're both just so sweet. Ore Monogatari is basically Saiki K with the roles reversed. Suna is way too similar to Saiki and Takeo to Nendo. The two anime are both hilarious, they both follow an episodic way of story telling, but Saiki is more focused on the daily and funny lives of Kusuo and his friends while Ore Monogatari is just a sweet ol' fluffy romance show.

Don't seem related at first, but enjoyed them for similar reasons. Both have a similar style of quick, cynical humour and clever writing, with Bunny girl senpai providing a more coherent story with a bigger emotional pay off.

Both shows are comedies that are totally hilarious. But the thing that makes both shows similar is the format as both shows are told in five mini-episodes in one compilation episode. Both shows are great comedies worth watching, but Saiki Kusuo is centered on one guy while Azumanga is about girls going crazy.

The two series are the showcase of the very best and the worst of J.C Staff. For the fan of both franchise, I recommend to watch these two until the end. It's enjoyable.

While the two shows are different, they share some similarities.

Similar vibes/tone/mood. No actual central plot and episodes are separated into three different sections about different random topics. Both are about the daily lives of the main character/characters with the main character being more of a judgemental, reactionary protagonist character.

I can't really explain it. But for some reason, every time I sit down and watch an episode of Urusei Yatsura (2022), it makes me think about The Disastrous Life of Saiki K.

Both are comedic flash animation shows, that focus on the protagonists' daily life, and how their troublesome interactions with others influence their lives. Saiki is a more "affectionate" high-school comedy, whereas Aggretsuko is a biting satire against the workaholism in Japanese culture.

Both MC's have a very simple goal (sleeping and leading a normal life) and are trying their best to achieve that goal, while being in a situation that makes this very hard to achieve (being held hostage in the Devon lord's castle and having superpowers). The comedy in both anime derives from the supporting characters reactions either to the MC or what's happening around them. So both anime have a pretty big and fleshed out supporting cast.

Psychological battles of sorts in bizarre settings. JoJo is campy while Psi is a parody, so they are different genres, but similar. Psi has references to JoJo, such as a Jotaro-lookalike in the early episodes, sound texts representing intense situations, characters spelling their character's strategy and thinking a counter to it, a glorious GAR narrator explaining concepts in a bombastic style, shorts arcs, a silent protagonist (mostly applies to Jotaro again), etc. Both are great anime, though JoJo is obviously the better one.

I am surprised this one has not been mentioned before. The main appeal of Saiki is not the premise (as interesting as it may be). Rather, it's the ensemble of wacky characters and the funny high-jinks they get into. This is something that Urusei Yatsura has a lot of, as well. As with Saiki, Urusei Yatsura has an ensemble of extremely endearing and lovable dumbass characters (with new ones being introduced periodically), always finding themselves in a new absurd scenario.

Saiki Kusuo utilizes 5 minute episodes to adapt a single chapter, and does so extremely well as the experience from start to finish is aimed at comedy first without anything in between. 3-Gatsu no Lion takes the chapters from the manga and adapts 2 per episode, which are about 25 minutes long, or 20 minutes if you take out the OP/ED.
