Synopsis

New book now open! Updates begin October 15! The overall direction will stay consistent with this book after the return to heaven. Updated September 27, 2026. Thanks for waiting. The sequel begins on October 15, 2026, with one update a day. The new book's promotional period starts during National Day. Can a boy become a magical girl too? (No.) What kind of story will unfold when Kaigaku from another world arrives in the world of Demon Slayer? Zenitsu, who transmigrated too, discovers that a lot of things have gone wrong. (Screaming and crawling.) Zenitsu will appear fairly late, and won't make a proper appearance until the middle of the story (Chapter 207). What do you mean all the Hashira know my big brother? What do you mean you have other younger brothers now? What do you mean I became Grandpa's favorite disciple? And you, blondie, get your hands off my big brother! I'm the only blondie allowed by Big Brother's side! The whole story is about family love! Kaigaku doesn't go from weak to strong. He's always been strong! A heads-up about the ending: it looks like a bad ending, but it's actually a happy ending. The death toll follows the plot of Demon Slayer! But they'll live on in another form! This is a free story, and writing isn't easy. Please give it a high rating (bows). I'm a new writer, so please be patient with me (bows again). Please help keep the comments lively (bows a third time). This book is a crossover between Madoka Magica and Demon Slayer! There are usually two updates a day, though there may be fewer on holidays. If a chapter gets more than 10 meaningful comments, I'll add a chapter. Suggestions and requests for additional scenes are welcome, as long as they don't affect the main outline. Thank you all for your support and companionship.

I've Run Out of Demon Slayer Fics That Interest Me. I Can't Keep Reading Them

I want to read something like *Demon Slayer: The Laid-Back Muzan Is the Ultimate Lifeform*. Ever since I read those few books I liked, I just can't get into anything else. Everything else feels so boring.

Kaigaku from Demon Slayer

Looking for stories like *Demon Slayer: I Don’t Agree with Your Sense of Justice*. I want to read Demon Slayer fanfiction, preferably with a happy ending for Kaigaku. No pairings would be even better, but pairings are fine too! More Kaigaku, please, from every direction (ᐢᴖ ·̫ ᴖᐢ

Stories That Treat Kaigaku Kindly

I want to read something similar to Demon Slayer: A Player's Guide to Raising Good and Bad Kids. It feels like in most Demon Slayer fanfics, Kaigaku cannot escape the fate of becoming a demon. I hope this guy can get lucky for once and stay alive all the way through.
