Demon Slayer: I Opened a Multiverse Library Next to the Butterfly Mansion

After transmigrating into the world of the Demon Slayer anime, he becomes a member of the Ubuyashiki cleanup crew.

His home beside the Butterfly Mansion has a library packed with cultivation manuals and secret techniques. Anyone else who studies them gets a hundredfold critical boost.

The Serpent Hashira: I heard the Love Hashira is staying at your place. I’m going to check it out.

Kanao: I’m clearly a member of the Kakushi, but Master is always comparing me to you. You have to take responsibility.

Demon Sister: The master of this place is really powerful. I want to hide here with Mom.

Muzan: Since I can turn into a woman anyway, I might as well become a daughter and learn the techniques here.

The secret about Hachigen Hyoi’s Library of Techniques from All Worlds couldn’t be kept under wraps for long.

So Sasuke, Naruto, Sakura, Tatsumaki, Fubuki, Lily the Three-Section Staff, Rin Tohsaka, Empress Hancock, and Goku all came by asking, “Can we get a discount on studying these techniques?”

Hachigen Hyoi: The guys can pay less. The girls can pay another way if they can’t afford it, ahem...

Tsunade: Let me study for free, and I’ll give myself to you when you come to Konoha.

Sakura: Sensei, first come, first served. I’ve already given myself to him~
