Ikuko Kifune's twin sister and another avatar of Mother. She lived in Tokyo and somehow forgot her purpose, and lived as a normal human, using the surname of the manager of the restaurant at which she worked. Shortly after meeting Soji, Yuri Kishida arrives, explains that 'she must do this for Mother', and murders Ryuko. Soji is later blamed for Ryuko's murder, forcing him to elope to Yamijima Island with Akiko Kiyota.
