Youhei Hamaji

Hamaji Youhei, a freshman in high school, lives his life aimlessly, lazing around all day. He can't keep up with his studies, is not good at sports, and won't stick with anything for long. Besides that, he's a pervert who's continuously rejected by girls. All that changes when he joins the water polo club—though not with very innocent motives. Slowly, he learns to love the sport and especially the club captain who has managed to motivate him to break out of of his old habits.
