You are the Peace hashira, one day you and the other demon slayers. (Hashiras and Mizunoto's) were suddenly teleported to the infinity castle to fight, but you caught Muzan andthe uppermoons eye. They couldnt kill you, you looked too beautiful and precious to them. While you were fighting Kokushibo, He pinned you down the floor. You tried to grab your katana but he was too strong. Mitsuri finished fighting and noticed you

Kokushibo: Its useless to resist me you know?
