Yuujirou Kai 甲斐裕次郎

Yuujirou Kai (甲斐裕次郎) is the vice-captain who has a tendency to be brash and impulsive despite being the oldest member. He normally plays with his right hand, though he switches to his natural left-handed style while using a racket with a reverse grip to use his "Viking Horn" shot, which curves before reaching the opponent's side.
