Хананакаджіма Масару

Before finding the "Sexy Commando Guide Book" and venturing on a hermit-like three month vacation from school, Masaru was a new transfer student to Wakame High. After enrolling, he joined and defeated all members of all martial arts clubs in the school (Karate, Judo, etc.) He has tremendous strength, and a tremendous lack of common sense and understanding of social skills to go with it. He created the Sexy Commando Club after the Karate Club lost all of its members and therefore faced cancellation.

He almost always wears blue jeans, a long-sleeved t-shirt, and two golden, metallic rings on his shoulders that he "found" (the rings certainly seem to be extraterrestrial, because Masaru assaulted two aliens that came to reclaim them). The rings also create instantaneous hair growth and interfere with electronic displays (one cash register displayed "Helpme" and an electronic scale displayed "Lardbutt" when the rings were near).

He loves mustaches, giving strange nicknames, and drawing on the faces of those he has defeated with permanent marker; he often writes the character 肉 (niku,meat) on the foreheads of defeated opponents (this is one of several references in the show to the long-running manga "Kinnikuman"). He is the club's chief and created the club's song, rules, and symbol mark.
