Sawa Nakamura

Оригінальне ім’я: 仲村佐和

A classmate of Kasuga who is portrayed as alone, isolated, and aloof. She has no friends. Nakamura witnesses Kasuga stealing Saeki's uniform and blackmails him to become her friend and form a contract. She displays hostile and rude behavior toward Kasuga, but can often be seen enjoying herself when with him. Though she maintains a usually sane and calm demeanor, Nakamura has occasionally had emotional outbursts when expressing herself to Kasuga. It is hinted that her desire to "escape" with Kasuga stems from a desire to no longer be alone. Nakamura earnestly believes that even if Kasuga chooses to stay or leave her, she will ultimately be isolated.
