Reincarnation anime with overpowered protagonists are common, as are isekaistories with child protagonists; however, these two lines do not cross all that often. If a show opts to go down the OP route, they tend to prioritize teenage characters, likely to line them up with their target demographic.
Whilereincarnated child MCsare not irregular, their vulnerability is usually emphasized (The Weakest Tamer Began a Journey to Pick Up TrashandAscendance of a Bookworm) or they excel in a specific area (Fluffy Paradise) that does not translate into a traditional power fantasy. As it can be a blast to watch a 10-year-old demolish massive monsters or powerful enemies, let’s highlight someOP child MCsin reincarnation anime.
Here are a few criteria and notes:
Isekai anime has a negative reputation for producing quantity over quality, with most seasonal shows struggling to leave much of an impression. Honestly,The Aristocrat’s Otherworldly Adventure: Serving Gods Who Go Too Faris a prime example of a run-of-the-millpower fantasythat does not try to shake up the reincarnation formula at all, and its defining characteristic is a protagonist who is younger than is typical for the theme.
While pretty forgettable, this anime is competent, offering decent animation, harmless characters, and a few memorable fight sequences. There is even a fun reveal that Cain, the child MC, is not the first Japanese person to be isekai’d to this universe. If somebody is just looking for an average OP MC isekai anime,The Aristocrat’s Otherworldly Adventureshould be a fine way to spend a few hours.
Isekai anime with OP protagonists prioritize action, as otherwise, what is the point of giving the MC cool abilities if they are not going to use them regularly? However,Didn’t I Say to Make My Abilities Average in the Next Lifeopts for something a bit different. While not devoid of action, this is acute girls doing cute things animethat just happens to feature four characters who can use magic.
Adele, the reincarnated child, is by far the most powerful character in the story, even though she specifically wishes to be reincarnated as an average person. While her overwhelming magical ability kills any semblance of danger or tension, that ultimately does not matter since the focus is on delivering lighthearted adventures set in a vibrant fantasy world. Depending on what a viewer wants,Didn’t I Say to Make My Abilities Average in the Next Lifemight not scratch their itch forreincarnation anime with OP child MCs; however, it is pretty entertaining.
Living as a doctor in his previous life, Kanji reincarnates in a medieval-style fantasy world as Falma, the young son of a noble family that specializes in pharmacy. While this world is not completely devoid of medical knowledge, Kanji’s familiarity with modern science puts him far ahead of the curve, allowing him to pretty much instantly become the greatest pharmacist. The fact that he has access togodly magicthat allows him to quickly diagnose a patient’s ailments or create substances from nothing does not hurt either.
Parallel World Pharmacyis a refreshing power fantasy. In other shows, the pharmacist aspect could have been treated as a gimmick that is discarded after the first few episodes, but that does not happen here. Falma quickly opens up a pharmacy and dedicates himself to the craft, and his medical practices seem to be based in reality. That said, he does get a few traditional OP demonstrations as well.
Except for maybe the first season ofMushoku Tensei,Saga of Tanya the Evilis the most famous isekai anime with a kid protagonist. That said, Tanya never remotely behaves like a 9-year-old, and she always comes across as an adult who just happens to look like a child. Still, there is something satisfying about watching alittle girl wage war against a godwhile serving as a general in an army that is very clearly inspired by World War 1 Germany. Her age and maniacal behavior add a comedic twist to an otherwise fairly straightforward military fantasy story.
Tanya is not as ridiculously overpowered as some other isekai protagonists, and she is weak in a few key areas like physical strength and mana. However, she just about achieves OP status due to her manipulative tendencies, connection to Being X (the previously mentioned god), and knowledge of WWI from her previous life, allowing her to have an edge in nearly every fight.
I Was Reincarnated as the 7th Prince so I Can Take My Time Perfecting My Magical Abilityis not an isekai as Lloyd reincarnates into the same world as his previous one.
Lloyd might just be thebest OP child protagonistever, mostly becauseI Was Reincarnated as the 7th Prince so I Can Take My Time Perfecting My Magical Abilitycompletely embraces the absurdity of watching a 10-year-old kid reduce powerful demons to whimpering messes. While he gets progressively stronger, Lloyd is a beast from the very first episode. He constantly goes out of his way to demonstrate his incredible magic, usually at the expense of an arrogant enemy who quickly learns the virtue of not judging a book by its cover.
Crucially, the anime has the style and production value to properly bring to life these showcases by delivering some of the most visually striking fight sequences in the reincarnation or isekai genre.I Was Reincarnated as the 7th Prince so I Can Take My Time Perfecting My Magical Abilityis also hilarious, with Lloyd’s power consistently sparking dumbfounded reactions from both enemies and allies.
