古手 桜花

The daughter of Hanyuu and Furude Riku. Though reluctant, she is the one who performed the Watanagashi ceremony on Hanyuu because Hanyuu felt that if she died, Hinamizawa would calm. She also left the chip on Hanyuu's horn when she tried to kill her. Ouka is the one who most likely started the tale of Oyashiro-sama's curse, possibly to scare the people in revenge for her mother's death./
