Koyomi needs to study for upcoming exams and is on his way to Hitagi's house for help. On the way there, Mayoi teases him about his one-on-one "study" session. Suruga Kanbaru, an underclassman, meets him as she is running, and she voices her admiration for him. Koyomi tries to get her to leave, however he is unable to until Hitagi is mentioned, at which point Suruga runs off. At the study session with Hitagi, the two discuss their future after high school, but things quickly deteriorate when Koyomi mentions Suruga. Hitagi and Suruga were friends in middle school and Suruga may have even had a crush on her, but they had a falling-out in high school. After studying, Koyomi calls Tsubasa for more details about them, but she warns him to mind his relationship with Hitagi and not to dig too deeply into her past too quickly. On his way to Oshino to drop Hitagi's payment off, Koyomi is viciously attacked by a person wearing a rain coat. During the fight he sees that the assailant has bandages dangling from its left arm. Koyomi is left bruised and bleeding on railroad tracks. Hitagi finds him lying there and tells him that he had forgotten the payment that he was supposed to be delivering. (Source: Wikipedia)
