Melody of Despair.Yuu is tasked as a member of the student council to ensure the safety of students with special abilities. During lunch, Jōjirō seemingly gets hurt after demonstrating his developing teleportation skills to Yuu in the cafeteria to grab some sandwiches. He tells Yuu that Nao has no female friends due to her selective invisibility power. A boy named Takehito Kumagami, who can detect people with abilities, guides Yuu, Nao and Jōjirō to Nanba High School. The three of them catch a student named Udō, who uses his thoughtography ability to produce X-ray photos of girls in their underwear, selling them for a profit to support his ill parents. After they threaten him, Udō agrees to stop using his ability. The next day, Nao takes Yuu to see her big brother, Kazuki Tomori, a musician who was experimented on for his ability to manipulate sound waves and has been left unstable and insane ever since then. Nao explains that, thanks to a particular person she trusts, she was able to escape from the school that experimented on her brother and to bring him to a healthier environment.
