Hand's

The main character wants to be a hero, but his father is a bum that loses all of their money in gambling, but he was once the ace of the japanese team in handball. He goes to a coach and asks him to take care of his son, because he got into a debt and is running from the yakuza. The coach thinks he's an outstanding talent that has been given to him to coach, and he sends his daughter to pick him. Daigo (the main character) then ends up living with them.
