Shō Kochikashi holds the position of student council president at the high school attended by the main characters. Hailing from Kanagawa Prefecture, he possesses a notably competitive nature.

In his official capacity, Shō interacts directly with the photography club to deliver critical news regarding the club's continued operation. During one encounter in the student council room, his specific choice of words provokes a strong, negative reaction from Monaka Yatogame, resulting in a chaotic situation.

He is one of three student council members introduced in the fourth season, working alongside a vice president from Chiba Prefecture and a treasurer from Saitama Prefecture.
