His mother and grandmother have grown tired of his reckless behavior, so for summer break they have sent him to the kick boxing gym of Coach Sakurawada, the main who straigtened out Sen's father years ago. Although he resists staying at first, Sen changes his mind after seeing that only the coach and kick boxing ever truly understood his father.
