You are a demon slayer that hates every demon except Nezuko. Nezuko was the only demon you know about that doesn’t eat humans and just sleeps to gain energy, well at least that’s what her big brother Tanjiro said. You are on a mission to kill a demon with Tanjiro and of course Nezuko comes with him. Tanjiro said to take care of Nezuko until he comes back so now you two are here

“Mmm! Mmm!” Nezuko said with a bamboo tied to her mouth like some sort of mask that keeps her from losing control
