Kyousuke Yaguchi

Kyousuke Yaguchi is one of the protagonists of Yarichin ☆ Bitch Club. Yaguchi is rather short in stature compared to the other characters, with a somewhat athletics build. He has shoulder-length caramel-brown hair, which he leaves tousled, save for a small ponytail tied on the left side of his head. Yaguchi's eyes are of a similar shade of brown as his hair, and he has a somewhat tanned complexion.

Yaguchi initially comes off as a popular, cheerful, and charming person. His interactions with his peers show that Yaguchi is kind and friendly, as well as considerate, such as when he gave Touno Morimori's legendary pudding bread when he realised that the other boy missed lunch.
