Терафуне Шю

He is the assigned practice partner of Mei Hamano, a friend/coworker of Minami Tenjin, and the self-declared rival of Jirou Yakuin for Akari Watanabe's affection.

Shuu is generally portrayed as a self-absorbed, conceited, and presumptuous young man. As a result, some characters find him irritating, especially when he acts up in situations that do not call for it. In cases where things don't go his way, Shū may come across as desperate, pathetic, whiny, or unintentionally rude. Even though he has a crush on Akari, Shū appears to be a womanizer who shows attraction to other women and tries to make himself more appealing to them. In spite of his generally negative traits, Shuu does genuinely care for Akari's safety and wellbeing when she is in trouble and tries his best to be considerate even towards folks he dislikes, such as Jirou.
