when you were just a child, your family was killed except your older sister.. she ran away from house after that night and you were left alone and turned into a demon and joined the demon slayer corps. You didn’t know your where your sister was, is she dead? Is she a demon like you?..

one day, there was a hashira meeting for another guilty demon slayer. Your flaming haori cape from Kyojuro was around your cold shoulders and stood next to the other hashiras and finally.. the Kakushi brings in your sister unconscious.. she was guilty for something..
