Yasumasa Teratani

He is Ichitakas 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 doesnt 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 wellmeaning but is also a jerk and a pervert and not exactly the smartest person in the series.
