Toru (Koki Tanaka), a delinquent high schooler, cuts short a fight with Tsuyoshi (Masaya Sakuragi), a delinquent from another school, and rushes home to make it in time for his lesson with his private tutor, Kishi Kishi (Rei Sawamura). Kishi Kishi praises Toru’s creative ateji like “Airabiyu” (“Love and Courage”) before beginning a lesson in classical Chinese. On another day, when Tsuyoshi mocks Kishi Kishi as “lame” for being a private tutor, Toru can’t hold back and ends up getting into another fight. As Kishi Kishi treats his injuries, he gently tells him there is a path to becoming stronger than winning through fighting. Motivated by the promise of a “reward for scoring 100,” Toru regains his determination to study once again.
