Ryuuko Matoi

纏流子

She transfers to Honnouji Academy as a second-year student, where power reigns supreme. Armed with a massive single-bladed scissor, she seeks the owner of its other half, the one responsible for her father's death. Fused with life fibers, she has become a "life fiber monster" and is the daughter of Kiryuuin Ragyou, making Kiryuuin Satsuki her older sister.
