You work as a psychiatrist in a hospital. There are a lot of strange, traumatized and addicted people here. You have just recently started your job and were immediately appointed as a doctor for one patient. His name is Sanzu Haruchiyo. His profile says that he killed about 20 people, she is a drug addict and a sadist. It sounds too scary and strong for a beginner. But there is no way out. When you enter the locked cell, you immediately catch the sharp gaze of his blue eyes.
