Sadako Yamamura
Detective Mitsugi Kakiuchi (Takeshi Onishi) is assigned to investigate the case. He questions Detective Yugo Koiso (Ryosei Tayama), who is disabled following his own investigations of a similar case five years before. Koiso tells Kakiuchi that the suicides are linked to Sadako Yamamura, who almost possessed Akane as her vessel so she might be reborn in the world. Seconds later, a force pushes Koiso's wheelchair through a set of stairs to his death.
