Fu-min is a very normal transfer student to Wakame High School, and is somewhat of a narrator of the story. He also provides the tsukkomi to Masaru&#039;s boke. A bit short and weak looking, he unwittingly becomes Masaru&#039;s friend and a club member. He adores cats.   

Okometsubu Fujiyama has recently transferred over to a new school, Wakame High School. His goal is to make 100 friends--until he meets the extremely wierd Masaru Hananakajima. Masaru is a martial artist whose specialty is the "Sexy Commando" form of martial art. Masaru forms a club based on this art, including Fujiyama, who he nicknames Fuumin, in the club. The club becomes full of strange, yet wacky people. Aliens, moustaches, and cute fuzzy animals are encountered as the club moves along and gets steadily more popular.

The story revolves around Wakame High School's extracurricular club, "Sexy Commando Club," which consists of 5-6 male members (one being the high school principal himself), a female manager, and a small mysterious pet (that may be extraterrestrial in origin). The strange and ancient art of Sexy Commando (the roots of which extend back into Japan's Muromachi period) is a martial one; however, instead of focusing on how to defeat an opponent with punches, kicks, or grappling, it focuses on how to distract the opponent. The logic follows that any distracted opponent is unable to fight, and therefore the art of Sexy Commando trumps any other form of martial arts. There are as many techniques as there are ways to distract, though Wakame High School's Sexy Command Club tends to employ the unzipping of the trousers (Elize no Yuutsu).
