Yamada Garfunkel Yoshio

The protagonist's bad friend and classmate. He is one-sidedly treating the protagonist as a like-minded person and his best friend. He thinks it is a nuisance for the protagonist, but for some reason, he is still with him.

He is half Japanese with a Japanese father and an American mother. He is a very handsome man with an aura of being popular, but he is only interested in 2-dimensional women and is a harmless, good-looking guy. His favorite erotic game genres are “tentacles” and “crying" games. He has been secretly working on a new genre that combines these two genres.

He and the protagonist are treated as one of the most perverted people in the school. The game “Magical Virgins: Tinkle Tentacle” has recently been released and he's really into it.
