Demon Slayer: Reborn as Muzan's Younger Brother

[Contains dark jokes about Japan, family bonds, childhood friends, the younger twin brother of Muzan, and an amnesia plotline for the protagonist. He will recover his memories during various plot events. Many side plots early on; the original main plot only begins in the middle and later sections. Mostly sweet fluff in a parallel world. Many added characters and original headcanons, so some characters may be out of character. No pairing in the main story except Snake and Love, with bonus chapters open to requests.] Takoyaki really is the key to another world, isn’t it? Dying from choking on takoyaki and transmigrating to another world: this ridiculous thing actually happened. As everyone knows, the reason for being reborn is never ordinary, so the world he transmigrates into won’t be ordinary either. Ouyang Yu, who choked to death on takoyaki because he was greedy from the start, then got buried at the bottom of a lake and lost his memories, says: “Huh? Does this mean I’ve got the protagonist package?” As it turns out, he doesn’t. After learning a few things, he successfully figures out which world he’s in. “Come on, in this era, the only place where demons eat people is Demon Slayer!” Ah, he wakes up one day to discover that he’s transmigrated to the Meiji era of the Demon Slayer story. He spends years searching for the original owner’s memories. Then, in the Taisho era, while wandering around, he meets a boy carrying a wooden box. “Ah, can I finally enter the main plot like all those transmigration protagonists?” Damn it, why is this guy chasing me for no reason? What? You say I’m the demon who killed your whole family? Damn, that was my brother! I only smell like him because we’re closely related. This is a misunderstanding! 1. Written at a middle-school level; the logic and emotional expression may be muddled. 2. Slow progress, with many side plots. 3. The author is a student, so updates are slow.
