Yuuka Sasaki

Yuuka Sasaki presents herself as an ordinary student at Isolated Island Academy, publicly claiming her special ability is superhuman strength — a carefully maintained facade. In reality, she wields the dark power of necromancy, bending the deceased to her absolute will. Beneath her charming, innocent appearance lies a deeply warped obsession; she murdered her own childhood friend Shinji with her own hands and transformed him into an undead puppet bound to serve her forever. The chilling contrast between her sweet exterior and her true nature makes her one of the most terrifying characters in the series.
