Yamada
A big, muscular member of the “real” Game Creation Club.
Despite having an imposing appearance, he is actually a very gentle and kind individual. He is sometimes shown accompanied by small, cute birds (most likely meant to represent his serene nature).
He, along with Inada and Sakuragaoka, joined the “real” Game Creation Club after the incident involving Roka and Chitose, and their recruitment allowed the club to keep from shutting down.
