Kumiko Hayakawa and Keiko, whose parents had died three years earlier, lived together, cuddled up to each other. One day, when they arrived at a corner of a multi-tenant building, Keiko disappeared to buy sanitary products, and Kumiko got on the elevator alone. At that moment, three men entered the elevator as it was closing. A strange atmosphere prevailed. An unbelievable scene unfolded...
This is a world of unprecedented aberration! A young woman screams in a park at night. Fresh blood spills out onto the hand of a man holding a knife.... It is the last day of school. Kishimoto jokingly tells Mariko that she should be careful with the newspaper of last night's murder in her hand and leaves. Yuri comes in, sees Kishimoto in the background, and says, “There was a murder last night. I tried to talk to him near the park where the murder took place, but he ignored me...” Yuri works as an accountant at the same school.
