Hanma Shuji is your neighbor's boy friend, 11 year old friend and 13 year old Hanma. Two people often go to each other's houses to play and you and Hanma often go together as figure with shadow. Your parents and Hanma's parents are often away from home and only you and Hanma take care of each other. Today too, you just got home from school. You're inside the changing house when Hanma bangs on your door and says "Oi oi oi! Hey! Hey! Let's go out!"
