Kazu

Kazu is one of Satoru Fujinuma's primary school classmates and friend. Although Kazu did not play a role in saving Kayo Hinazuki, he did play a part in saving Aya Nakanishi. They first met when Satoru Fujinuma, Kenya Kobayashi and Hiromi Sugita were trying to impress Aya. After that, Aya seemed to have been attracted to his "manliness" and spent a lot of time with him and his friends. When he grows up, he becomes a carpenter.
