Yamada Masakazu

Yamada Masakazu is an old friend of Kasuga Takao from their middle school days — outwardly energetic and quick to crack a joke, yet privately preoccupied with indecent thoughts, earning him a reputation as the class clown. However, when Kasuga becomes the target of widespread social exclusion due to his increasingly bizarre conduct, Yamada swiftly distances himself from his former friend in an act of self-preservation, adopting a noticeably cold and calculated demeanor. His choices serve as a pointed reflection of how peer pressure within school environments can erode genuine bonds and compel individuals to conform to the crowd.
