Isekai Reincarnation Manga Guide #Winter 2025 Anime Edition

For the past ten years or so, isekai reincarnation manga have been popular. There is no sign of people getting tired of them, and the boom has been going on for a long time. Even in anime, multiple isekai reincarnation titles are produced every season.

This time, I will introduce my recommendations from the Winter 2025 anime lineup.

1st Place: Uncle from Another World (Isekai Reincarnation Ojisan)

This is such a popular work that I just have to say, 'Please watch this this season!' The YouTube view count has even exceeded 1 million.

The premise that a serious 52-year-old civil servant uncle reincarnates as a young lady in a game world is just the best. He pretends to be a villainous noblewoman while keeping his uncle-like thoughts inside his brain. It's hilarious how he doesn't panic or get flustered about having reincarnated, but instead calmly thinks about how to speak and act to behave like a young lady in this other world. It's also relatable and endearing that he has typical 'uncle' traits, like not being able to remember foreign names.

Actually, since it's the world of a game his own daughter was playing in the real world, he has some knowledge of this world. Why did the uncle bring an abacus to the other world, and why is it popular?! And the ending theme is
Matsuken Samba. A mystery lol. Well, anyway, please watch it.

2nd Place: Welcome to Japan, Elf-san

Welcome to Japan, Elf-san. Episode 1 'Good Morning, Elf-san.' - Niconico Douga

This is a romantic comedy that will make your heart flutter. Marie the elf is just so cute!

Kazuhiho, a human in the real world, reincarnates into an isekai in his dreams. If he dies together with the elf he met there, the elf then reincarnates in reverse to Japan, a setting where you can enjoy both worlds.

It's refreshing and lovely to see the elf trying hard to study Japanese and genuinely enjoying Japanese food and culture. She eats things like gyoza and hot pot that appear on the dinner table so deliciously that it makes me hungry too, so in a way, you could call this a gourmet manga.

3rd Place: Sentai Red Becomes an Adventurer in Another World

Sentai Red Becomes an Adventurer in Another World Episode 01 'Sentai Red and the Mage' - Niconico Douga

Most isekai reincarnation stories feature a NEET otaku who dies and becomes the protagonist, but here, Kizuna Red, the leader of a sentai hero team from the real world? called Kizuna Sentai Kizuna Five, reincarnates into the other world just as he is! That premise alone is a win, right? Plus, he doesn't use magic in the other world; he just uses his real-world finishing moves to defeat monsters. Weapon names and finishing move names that hit the spot, like


Handshake Calibur (Excalibur?) and Bond-Beam Gun, are irresistible.

It also has that classic, passionate development that kids love, where the bond between two people strengthens and they shout Kizuna Power Up!. I wish this aired on Sunday mornings instead of late-night anime.

4th Place: Zenshu.

Zenshu. Episode 1 'Starting Line.' - Niconico Douga

A genius anime director eats a clam bento, dies of food poisoning, and is reincarnated into another world. It turns out to be the world of an anime movie he was familiar with.

Much like the Red Ranger, there has been an increase in settings where protagonists of various professions are reincarnated. The development where they use the knowledge and common tropes unique to their profession—in this case, an anime director—to engage in trial and error in the reincarnated world really hits the mark for viewers.
While the pacing and setting of the first episode are excellent, it is a shame that it becomes redundant and loses momentum from the second episode onwards.

5th Place: The Middle-Aged Man's Isekai Online Shopping

↑YouTube is for the trailer only

Kenichi, a single man, is reincarnated into another world. For some reason, he discovers he can use the online shopping site Shangri-La (Amazon?), allowing him to do whatever he wants, such as selling glass beads to perform alchemy, or using heavy machinery from the real world like light trucks and excavators to defeat monsters and build houses.

He dominates not with magic, but with mail-order items.

How was it?
There are still many more, but there are too many to keep track of. First, please take a look at the manga and anime in 1st and 2nd place.
