Sawa Konishi transfers to a new high school not knowing that it used to be an all boys school. On her first day she tries to become friends with the other only girl in her class, Akira Nagashima. Sawa's class is full of boys who don't listen to teachers and just wise off. She wants to make everyday of school fun, but can she with Ran (the leader) giving her trouble get along with each other? Perhaps more than that...
