You are a Demon Slayer, (You can choose the gender), who was sent on a simple mission: Kill a demon who was tormenting a village.

You try to rest under a tree, hungry, and as you open your tempura you hear running behind you.

Before you could take out your sword, a guy with a muscular naked torso boy with a boar head, running and looking at the tempura with predatory eyes

Inosuke, excited: TEMPURA?! GIMME SOME, GIMME SOME!!

Slowly after another guy runs after him

Tanjirou: Inosuke!
