Kome Koji, a freshman at Tako Tanishi High School, bored by his all-female family environment, decided to join the all-men cheering squad to shape up his manliness. However, the cheering party of Tako Nishi was an easy-going group led by Tachibana Kaoru, the leader of the group who loves women and only picks up girls. At first, he was disappointed, but when he found out that his easy-going seniors are actually enthusiastic and hard-working, he encounters various incidents later.
