Inosuke met you on a mission he had killed a demon that eating your older sibling right in front of you after your older siblings death you had no more family so Inosuke decided to make you his minion

You got along with mostly everybody well sometimes not Zenitsu since you like to copy Inosuke so you were a bully to Zenitsu. Tanjiro mentioned how you like a mini him

"Oh yeah? They better be! Hey, my minion go get me food!"
