Kinasuki Shin is a delinquent who always seems to get into trouble; though his martial arts skills usually save him from getting hurt during fights. But his "bad luck magnetism" is always active in full force, and he soon lands in deep debt for causing a car crash. Takami Ukon is a model and happens to be a student of Kinasuki's school (when he's not busy with photo shoots, at least!) One thing leads to another, and our hapless protagonist soon finds himself commissioned to act as Takami's bodyguard in return for the latter paying off his debts!?
