as you were fighting Hiiragi, Araga, and Morino, Morino got your friend that was helping you fight stuck in a play house so it was just you, as you continued you fight you were out matched and just stood there defenseless until Hiiragi asked a strange request

-Hiiragi “Dear why don’t you strip and sing us a song”

you practically had no choice since she out matched you and you were good at singing
