Sawa Nakamura  

, 仲村 佐和

A classmate of Kasuga who is often depicted as solitary and distant. She lacks companionship. Nakamura observes Kasuga taking Saekis uniform and uses this as leverage to make him her friend and establish a contract. Her behavior towards Kasuga can be hostile and impolite, but she also enjoys his company at times. Despite maintaining a generally composed demeanor, Nakamura has had moments of emotional intensity when communicating with Kasuga. It is suggested that her desire to "escape" with Kasuga stems from a need for companionship. Nakamura firmly believes that even if Kasuga decides to remain or depart, she will always be alone.
