Seizaki explains to officer Sekuro that Ai Magase was being seen by her uncle, Doctor Kurauzu Sakabe. They visit the doctor who says that Ai was adopted and when he conducted psychological evaluations of fellow male students, they all reported the experience of being raped by her merely through her physical presence. Her effect was so strong that even Sakabe was affected by it and eventually resigned his position. Seizaki and Sekuro take time out and practice kendo when Itsuki releases another public statement, proposing a debate on the suicide law at the NHC television studio. Seizaki immediately commits the investigation team to finding evidence Itsuki abetted suicide. Later, Magase calls from Investigator Tsusui's mobile phone saying that she wants to bring happiness to the world, then Tsusui runs onto the road where he is hit by a truck and dies with a smile on his face.
