; : :Masaru, a transfer student at Wakame High, dominates all school martial arts clubs before discovering the Sexy Commando guidebook and taking a three-month absence. His immense strength is matched only by his lack of social awareness. When the Karate Club faces disbandment due to member losses, he founds the Sexy Commando Club. He consistently wears blue jeans, a long-sleeved shirt, and two mysterious golden shoulder rings—likely alien technology given their effects (causing rapid hair growth and disrupting electronics) and his violent encounter with beings attempting to reclaim them. Known for his love of mustaches, he marks defeated opponents' foreheads with the kanji for 'meat' () (referencing
Kinnikuman). As club founder, he creates its anthem, rules, and emblem. Though he once called himself "Shōjo Commando" in childhood, he abandons this title after his father's intervention. ; : :Nicknamed , is a very normal transfer student to Wakame High School, and is somewhat of a narrator of the story. He also provides the to Masaru's
boke. A bit short and weak looking, he unwittingly becomes Masaru's friend and a club member. He adores cats. ; : :Nicknamed , is the tall, blond former chief of the Karate Club. Once Masaru joins the club and defeats all the club members, all students involved in the club quit and Machahiko must recruit new members before the club is disbanded by the school. Masaru then offers to help, and the club is saved, but the name of the club is then changed to the Sexy Commando Club. Machahiko can be instantly encouraged or discouraged by mentioning that what he does is either "manly" or not. ; : :Nicknamed , he has hair dyed brown and is a completely emaciated bag of bones, in part due to his addiction to vitamin supplements. He joins the club in order to become stronger, and for a brief period does become stronger, giving up the vitamins for food and exercise. Unfortunately, his reliance on vitamin supplements continues, and every time he takes them, so does his spasmatic cry "Okure-nisan" (a reference to Japanese comedian , who is also extremely thin). He was also the ace of his baseball team in middle school. ; : :Nicknamed , he joins later in the story, and is a semi-minor character. After begging Masaru to make him more "individualistic", Masaru gives this model nerd a perm, and then names him "Afro-kun". An opposing Sexy Commando team member later rips two holes from the afro and his hair assumes a more triangular shape. He is extremely smart, but has no sense with girls. ; : :Nicknamed , he is actually a former Sexy Mate (Sexy Commando participant) who won the All-Japan Sexy Commando Tournament six years straight. He was formerly a teacher and now is the principal of the school. He suddenly aged when he expended all of his energy pushing the school off its foundation in order to inspire a lazy student (who later became
Prime Minister of Japan). He dons a red ski mask when he wishes to become Susan (and hide his identity to Masaru). ; : :Nicknamed , she joined the group initially believing that the club was actually the "Mustache Club". She shares Masaru's love for facial hair, as her father died trying to grow the "legendary blue mustache". She is always supportive of the others in the club. She also spends a considerable amount of time with Meso. ; : :Nicknamed , he is an annoying P.E. coach that sponsors the Sexy Commando Club. He always wears training pants (thus the nickname Torepan), wears aviator sunglasses, and is always tweeting away at a coach's whistle. He one time bets the club's endowment money on a baseball game (Sexy Commando Club vs. Baseball Club) that the Sexy Command Club subsequently wins. The club members pay no attention to him, and consider him a nuisance. ; : :It is questionable what Meso is, because even though the cute, little yellow munchkin with a blue mustache for eyebrows is the mascot of the team, its zipper (located on his back) has opened various times and various other lifeforms have emerged from inside (the anime's finale has Maetel from
Galaxy Express 999 come out). Meso's usual comment is . It has been known to be extremely violent when threatened, and has an impressive set of fangs and claws. It was found on either a spaceship or in a coffee shop called Dosukoi Kissa Je T'aime, depending on the club members' opinions. ==Media==
