Teratani, Yasumasa

寺谷靖雅

He is Ichitaka's best friend, who considers himself an expert with the opposite sex despite his somewhat nerdy look and lack of success with girls. He is frequently seen offering Seto encouragement and sound advice. Although his assistance is occasionally unwarranted and sometimes leads to unfortunate situations, his intentions are good, and he feels disheartened when Seto fails. Ichitaka spends a significant portion of the story repeatedly seeking his counsel, but as the narrative advances, he learns to depend less on him. He is generally viewed as well-meaning, yet he is also a jerk and a pervert, and certainly not the smartest character in the series.
