蟹沢 きぬ

Kinu is a second year student from class 2-C, Reo's classmate and one of Reo's childhood friends. She is a late riser, and so Reo usually wakes her up. Her pet name is Kani or Kanicchi.

She is flushed with anger when anyone calls her by her personal name Kinu, because she has an inferiority complex due to her name. Yashi Nagomi who often quarrels with her has nicknamed her Koukakurui (甲殻類) meaning crustacea.

She is extremely short-tempered and hates to lose, and her school work is awful. She has many friends because she has a cheerful disposition. She is popular with males, and often is confessed to. She always declines confessions since she is has high standards in taste for her boyfriend.
