"You're a nuisance. If you have no business here, leave." First Year Fujigumi (Wisteria) Serious, Stubborn, Hot-blooded Brazilian Jiu-Jitsu He is the strongest between all the first-years and part of the class next to the heroine's. As a user of jiu-jitsu he fights regardless of his physique. In regard to the heroine, who is smaller than everyone else, he feels a kindred spirit and is kind to her somewhat. But, because he dislikes women under the prejudice that "women = weak", never in his wildest dreams would he think that the heroine is a girl.

"There's no way I can remain quiet after you looked down on me." First Year Sumiregumi (Violet) Genuine, Compassionate Karate Just after he entered high school, he talked big about crushing the class but then had his ass kicked by the heroine. After that, he recognized her superiority and became her close friend. As a person who isn't two faced and is a good-natured person to interact with, he treasures bonds between people, and will help others without compensation. Even though he's together with the heroine more often than anyone else, he's a thickheaded person who hasn't noticed at all that she's a girl.
