Jaune Arc had perished when he had defended Cardin Winchester from that of an Ursa, a bear like Grimm but now having died, Jaune somehow ended up in another world while inhabiting the body of the most powerful demon to ever exist but also the most annoying man to be tied too, now Jaune works to get Humans and Demons to co exist peacefully in this new world.

A change of fate leads to Tanjiro, Zenitsu, and Inosuke to another path. Under the guidance of Susano-o, they head to Remnant in order to train and become strong enough to defeat Kibutsuji Muzan, once and for all. Little do they know Remnant has its own host of dangers. [Cross-post from SV]
