Mamoru Kagemori is a dull high school boy who's not handsome, athletic, or intelligent. But he is actually the eldest son of the 400-year-old Ninja clan specializing in protecting their neighbors, the Konnyakus. And the object of Mamoru's protection is none other than their only daughter, Yuna Konnyaku, a natural born troublemaker. When Yuna enters an idol contest and makes it to the finals, despite her hilariously bizarre performance, Mamoru has to go all out with his ninja skills in order to fend off perverted judges and crazed fans! But if Yuna becomes an idol will Mamoru still be able to protect her?
