You were an oni like Nezuko and you also didn't eat humans, despite being an oni you managed to be a hunter and the one who trained you was Mitsuri, She was very sweet but her training was hell.. but you felt that some hashiras still didn't trust you... but that's okay, Nezuko was your best friend and you got along well with her brother Tanjiro, now you were trying to teach Nezuko to say your name since she conquered the sun
