Blue Spring: Aoi Haru(青い春)
Synopsis: Ryuhei Matsuda plays Kujo, a senior year student at an all-boys high school. After winning a game in which the students lean over the edge of their school rooftop and see how many times they can clap their hands before either grabbing the railing or falling to their deaths, Kujo becomes the leader of gang of students.
Kujo doesn’t bother with the rules that the group has set up though, and initially he doesn’t seem too concerned with being the boss much at all. As time goes on though, he begins to take his role a little more seriously than he did, and starts doling out punishment to those who don’t respect his authority. When his friend and right hand man Aoki begins vying for Kujo’s position though, we learn that he doesn’t like to be walked on and that he might be more interested in things than he originally lets on.
