Mamoru Kagemori is a dull high school boy who's neither handsome, athletic, or intelligent. But, he IS 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!
