Detective Conan in Demon Slayer

Fanfiction + no romance

Edogawa Ranpo is chosen by a System created by the world’s will and transmigrates into the world of Demon Slayer.

He is tasked with repairing the rifts in his original world. By killing demons, he powers the System, which can draw companion cards.

Companions such as Fukuzawa Yukichi become cards and assist him.

And so he begins his demon-slaying journey in another world, all so he can eventually return to the world he came from.
