Defcon☆One

In 'Defukon Wan,' Hiroshi is a hopeless pervert who falls instantly in love with Tetsuko after accidentally seeing her. When he lunges for her chest, she rejects him flat. In a rage, he kicks a trash can, which flies and hits a passing girl named Sora on the head—but it saves her from a falling construction beam. Sora, an army fanatic from a wealthy family, feels indebted to Hiroshi for saving her life. She accepts the "mission" he proposes: find him a girlfriend, or simply "a woman who lets him touch her butt and breasts." Step one involves a helicopter transporting Hiroshi's all-boys classroom to a prestigious all-girls school. Thus begins their hilarious, chaotic school life. DEFCON stands for DEFense CONdition; see Wikipedia for details.
