He presents a photograph of Toshikazu Hazamada, a fellow student in Josuke's highschool, and reveals that after a dispute with Hazamada, one student gouged out his own eye with a pen, an action the student claimed didn't do by himself. Josuke decides to investigate Hazamada, and Koichi accompanies him, which inspires admiration in Tamami, who still leaves.
