Sentai Red Isekai de Boukensha ni Naru

The Red Ranger, Tougo Asagaki, finds himself transported to another world in the middle of a fierce battle against forces of evil. Upon arriving, he quickly makes a name for himself as an adventurer and takes on a job from a young mage named Yihdra Arvoln. With his eccentric powers and frenzied personality, Tougo blazes through the mission with her.

After the quest, Tougo and Yihdra begin adventuring together with their respective goals. Tougo strives to help as many as possible in the new world and find a way back home, while Yihdra desires to redeem her family lineage of mages and make magic accessible to everyone. Along their journey, the duo discover the limitations yet endless potential of the bonds they forge as they overcome adversities to achieve their aspirations.

Sentai Red Isekai de Boukensha ni Naru is an enjoyable and exciting watch as this anime is an essential Power Rangers iseaki. I say it's a must-watch if you grew up watching shows like Power Rangers, Super Sentai and Kamen Rider and even if you didn't it never hurt to give something a try, right?

The anime really likes to poke fun at the classic Super Sentai and Tokusatsu tropes and standards through the overuse of onomatopoeia whenever there is any chance. By all means, this does not ever get boring and instead adds to the charm of this anime due to it's epicness during ... fights and addition to the comedic aspect of the show.

The main character in this anime, Red' is a funny and adventurous character who only cares about forming and protecting "Bonds" with other individuals and takes does everything with 110% effort. The "Bonds" also serve as his power source throughout the anime, as he uses his these "Bonds" to help him fight against his foes through his assortment of relationship based weaponry and ultimately his Kizuna Beast, which can transform into a MEGAZOID. A main point of this anime is Red's absurd powers in this isekai world. As the world is that of a fantasy world, so it's always great to see whenever Red uses his powers and especially his megazoid to fight his opponents that are always blown away by his mecha.

Additionally, Red meets many people whom he forms "Bonds" with as he travels with his new team to put an end to nefarious plans of demons that wish to resurrect the demon queen. Besides Red, there are many enjoyable side characters in this anime, such as the mage Yihdra, who has the strongest 'romantic bond' with Red and wishes to become the top mage in the entire kingdom to average her father. Yihdra and Red's relationship also makes for some hilarious moments, as this mage keeps getting blown away by all of Red's sentai gear and the megazoid that he can summon to this world of swords and magic. Also, other characters like the princess Teltina and the hero Lowji join Red on his adventure as together they fight corrupt and evil lords to protect the kingdom.

The OP is also absolutely fire, as it fires you up and gets you excited about what you're about to watch.

If you enjoy isekai and tokusatsu based animes, why not enjoy this one which is a mixture of both. Sentai Red Isekai de Boukensha ni Naru is epic as you let yourself become immersive with the epic music, sound effects and action, along with its constant comedy. I highly recommend this anime for any fans of super sentai shows as you will thoroughly enjoy it.

Mixed Feelings

I knew it would be a parody and wasn't expecting much to begin with.
The sentai aspect of the show is nice but outside the megazord and desert ranger (evrything about it was nice) the art was uninspiring and bland.
The plot is okayish.. little conveniences couple of times. Only surface level knowledge on characters, I still am not sure about how the mc sees his isekai party.
Music , there isnt much to talk about it
Jokes are not cringey so thats a plus.. still not as hilarious.. mostly just routine gags, I liked the naming of gadgets and things tho
Action.. you know how it is power ... ranger/ super sentai

overall, a decent watch.. worth a try if u like power rangers and got nothing else to watch

“The Red Ranger Becomes an Adventurer in Another World” is what happens when a wacky idea meets generic writing.

The show starts off pretty cool. Something wacky, over the top and with a lot, I mean A LOT, of potential. It ends as a boring, stale, “you’ve seen it a million times”, generic isekai. Shame, but after the disappointments of the last decade I really shouldn’t be surprised.

Before we start I would like to explain something. I will be talking about “plot” and “story”. Many people use those terms interchangeably. I’m not one of those people, so to make sure everyone is on the same ... page…
I use the definitions for “plot” and “story” as Lisa Cron describes them:
“What happens in the story is the PLOT, the surface events.”
“STORY is about how the things that happen affect someone in pursuit of a difficult goal, and how that person changes internally as a result”.

Let’s be honest. Anyone who knows anime, light novels and some cheap movies, could tell from episode one what kind of protag we get. Every damn time when I see an MC (this time it’s Red) who is OP AF, is optimistic and acts like a try hard comic relief, he also has a tragic, generic, sad backstory. Especially if that MC is a comic relief despite bringing in an objectively shitty situation. If you didn’t get that at the very most episode 3, You are either new to anime, or You’re a damn liar. The thing is, his backstory didn’t make me sympathize with him, it made me just despise the organization (Yes, I will call it an organization, they have their own HQ and at least one R&D wing with at least one personnel so it’s not like it’s a bunch of kinds in a tree house),he is working for — The Kizuna Five. But I’ll get to that.

So yeah, the story… there is none. Seriously. Red just rolls with whatever the wind blows his way (is that the saying? I’m not sure). By the time we see Red in the new world it has already been 6 months after his transportation. He became an adventurer that just does jobs to survive. That’s it. It is stated in the very first episode that he spent time searching for a way to get back home right after he arrived and that he saw probably most of the world and witnessed people's plight. Ok, fine. Give me that. That sounds like a much better story than the crap this show serves for the next 12 episodes. I want to see a protagonist that has a goal and is motivated to achieve it. I don’t want to see him as a passive, optimistic comic relief. I want a proper protagonist with a proper story, not another passive moron. And don’t give me that “It’s a parody so it doesn’t need a story or logic”, eff off, just eff off. If You really think that then You probably never experienced a proper parody or satire (they are not the same) in Your life.

If You’re expecting the plot will pick up the slack… it does… in the last two episodes. Before that You get 10 episodes of absolute cliché. There is not one original thought in this show. Now, that alone isn’t such a big problem, a lot of anime use cliché ideas, it all depends on the execution of those ideas and this show… well… on one side it actually fits the super sentai vibe, on the other it just adds to the flatness and no stake state of the whole show. You have to defeat a giant monster? Use a giant robot with a giant sword. You have to defeat another giant monster but can’t use the giant robot? Use a giant gun. You need to kick the ass of powerful, human size enemies? Punch it in the face. You need to take care of two uber powerful enemies at the same time? Use a powerup that was stuck up Your ass for the whole time. You see a pattern? Every enemy is taken care of by brute force and nothing else, even if that makes little sense. But You know… the power of friendship is definitely powered by violence.

In the spirit of super sentai / power rangers Red has access to a giant robot. You know the type, the type that is created by combining 5 smaller robots that are piloted by other members of the team. The problem? Why the fuck Red can use it solo? He can summon all five robots and combine them at will. No need for other people with morphers. He can summon any one of them. We see him summon red and blue on their own. If he can use it solo why the fuck have a whole team? One person would be easier to control than 5 so it would be easier for their bosses to have a powerful weapon on a tight leash. Apart from fighting mobs there is no point in having a 5 member team if just one is enough to use the most powerful weapon. Give me some kind of explanation for that.
On the subject of robots. He can summon them. His team back home is aware of the fact that the robots were deployed and yet… not one of those morons thought of... I don’t know… leaving a fucking note in the cockpit? A simple sticky note with the words “Hey, Red are You ok?” in the middle of a damn controler? No? Just me? Ok. I can believe Red hasn't thought of that, he is a moron, but others? Blue seems to be smart and yellow is a damn teacher. Guess despite having advanced robots and weapons at their disposal a sticky note is beyond their technology tree. They could communicate in that way and at least try to solve the isekai problem.

I’m not sure if Red is dumber than I thought, is suicidal (well… he is but that’s another things) or just brain washed but Kizuna 5 team is more than just a little villainous. I mean… they use kids as soldiers. Not only that but Red has clearly PTSD and it seems not one person on his FIVE people team thought that maybe he should get some off time for therapy? It’s not like the morphers can be used only by one person. They are recruited from the population so anyone can use them, why don’t they have 2-3 full size teams that rotate the use of the morphers? That way everyone can get proper debriefing, psychological help and some much needed time off. Red lost his parents, the girl he probably had a crush on died basically in his arms and Kizuna 5 did jack shit for him. I would understand this if it was a case of “Only the chosen one can use this device”, but it’s not. Yeah… let’s have a traumatised kid with deadly weapons and WMD just hop back to situations that might induce more trauma. What can go wrong? Seriously these guys have some shitty bonds.

The best part of the show is Yihdra (the female lead). She starts out awesome. An idealistic, pretty naive mage with a boner for R&D. She wants to study Red’s power to create a new type of magic. I’m all for it. So why the fuck she drops it almost immediately after getting the quest from the princess? I get that without a proper lab her options are limited but even on the road she should be able to do some basic research. Over the whole show she does exactly one thing that could be interpreted as research and development and the damn thing works from the get go. No miscasts or failures. She’s such a wasted potential. A logical, methodical character turned a jealous girl in love. That’s just pathetic.
Remember when I said there is no story? That was half a lie. There is a story but not Red’s. The story mainly revolves around Yihdra and how she matures both as a woman and a mage. She sheds off some of her naivete and even learns to be honest with her feelings. Those are all good story beats. The problem? The show treats all of them as either after thought of just background.

That said, I can understand why some people would give this show a high score. It is almost like a love letter to both fantasy and super sentai. It uses a lot of cliches and tropes from both. From the power of friendship to get powerups, being used by royalty, getting sent on a fetch quest only to get more than You bargained for and gathering powerful allies like they are pokemon. Yes, they are cliches and I despise cliches but I understand that I’m in the minority on that front. If this show wasn’t so safe and sterile I would probably like it despite the bad writing.
But as it stands I only recommend the first and last 3 episodes. The rest is just boring stuff you saw a million times. At least it's not a harem.
