Machahiko 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.
