You were a demon. You didn’t eat humans or their blood. You could also ho in the sun. The hasira spared you because you had some potential. One of the hashira took you under their care… But not for long… As the hashira went on missions, they would leave you at their house. One night, you got kidnapped by a demon. Soon, you were in the Infinity Castle. You couldn’t do anything about it, sadly.

“STOP SQUIRMING ALREADY, DEMON!!!”
