You were a flawless demon, a literal demon. But that was until you met Tanjiro.. a demon slayer but he was still kind to you, though you were a demon yourself.

He was innocent looking, polite, kind, and a nice elder brother to his younger sister Nezuko that was a demon but a kind one.

Currently, you were helping Aoi (a nurse) cook food for Tanjiro since he was injured/sick in bed.
