Yasumasa Teratani

寺谷 靖雅

He is Ichitaka's best friend who seems to think himself a pro with the opposite gender despite his somewhat nerdy appearance and lack of success with girls. He is often found giving Seto encouragement and good advice. Though sometimes his help is unwarranted and sometimes ends up in a bad situation, he means well with his actions and is bummed when Seto doesn't succeed. Ichitaka spends a considerable amount of time through the story continuing to ask for advice, but as the story progresses he learns to not rely so heavily on him. He is generally interpreted as well-meaning but is also a jerk and a pervert, and not exactly the smartest person in the series.
