Satoka Ryoudou

Kana Juumonji was once a student at Ryukoyou Academy where she killed 5 girls. She was the president of the drama club and an outstanding actress. After being caught she pretendet to be hysteric to escape the punishment. She soon got free and changed her name to Satoka Ryoudou. She debuted as the lead character of the movie 'Cleopatra 2nd generation' after driving the actress Misaki Touno into suicide. After many failed attempts to kill her rival Shiho Kobayakawa, Shiho made Satoka experience a shock strong enough to make her lose all her memories thus turning her mind back into that of a toddler.
