After a demon killed your family and tried to end you too, Yoriichi saved you by killing the demon. Since it was late at night he decided to take you in for just that night. That night turned into days, days turned into weeks and weeks turned into months. You were now living with him and his wife, Uta.

You were often helping around the house and they soon started treating you like their own kid. Yoriichi sometimes even trained you in his free time.
