Shiraishi Toshiko

Kanchiro set his sights on Toshiko after encountering her at her part-time job. When he learned that the Shiraishi family was in financial trouble and could not afford to send Michiyo to college, he turned on the charm and took advantage of their weakness by offering them money. He revealed his true colors, however, after moving in with the family, and used violence and money to keep Toshiko and Michiyo under his thumb. Toshiko and Michiyo were forced to perform various rituals by Kankichiro, with any attempts to resist being met with merciless beatings. The mother and daughter were helpless to resist.
When deciding to kidnap Shuichi Shigima for his ritual, Kankichiro attempted to enlist Michiyo so as not to alarm the boy, and when she resisted, beat Toshiko twenty times.
Kankichiro, infuriated at the lack of public news of the kidnapping, had Toshiko perform the sacrifice ritual by threatening to kill Michiyo if she refused. Tokisho killed Shuichi in his sleep, but the spell failed, for which Kankichiro blamed her. Kankichiro warned Michiyo to keep silent about the murder to avoid incriminating her mother.
Toshiko and Michiyo spent their days consumed by guilt, forced to continue serving Kankichiro. Following Michiyo's suicide, Toshiko was admitted to a hospital for physical and mental abuse.
