Height: 172cm, Weight: 60kg, Blood Type: AB. Leader of the Kimengumi. Known as "No-Brows Rei." First person: I (polite/soft). Ends sentences with "-na no da." He formed the Kimengumi with the motto "Pursuit of Individuality." He hates trying to be like everyone else and values uniqueness above all. Consequently, he has the strongest personality among the members and frequently switches between a 2-head-tall chibi form and a 6-head-tall serious form. He sometimes even transforms into non-human objects. While he is often mocked by classmates and even his own members, he lives by the motto: "Rather than being a gear in the world's machine, be the seasoning that gives the world flavor."

Blood Type: O, Height: 172cm, Weight: 60kg. Known as "Big-Eyes Go." The number two of the Kimengumi. First person: I (rough/masculine). Characterized by his crew-cut hair and thick eyebrows. His entire body is hairy, and he can walk on water using the oily hair on the soles of his feet. A pro-wrestling fan, he calls himself "Crusher Go" and often mimics wrestling moves. He is foul-mouthed and lacks amiability or kindness. He is also bad at lying. He is short-tempered and quick to resort to violence, but he generally refrains from hitting women. Because he uses violence, his physical strength and stamina are superior to his classmates, making him a strong fighter. However, he also has a cowardly and petty side, so he avoids facing opponents stronger than himself head-on. Since his family runs a liquor store, he loves alcohol despite being a minor, and has even smuggled large bottles into middle school field trips and high school summer camps. However, he claims he has never brought alcohol into the school building itself, maintaining a personal line of discipline. According to him, his "best subject is English," but he only understands English pro-wrestling terminology (e.g., Backdrop). On the other hand, because he lives with his uncle and aunt, he is careful to live quietly in his room and helps out by delivering liquor.

Blood Type: B, Height: 175cm, Weight: 60kg. First person: I (soft/polite). Characterized by a face that always looks like it's smiling and large earlobes. His personality is extremely gentle, mild-mannered, and easygoing. Most of his day is spent sleeping or resting. An extreme slacker. Possesses an abnormal appetite, eating nearly 1.8 liters of rice for breakfast. He is a habitual sleeper during class, but wakes up the moment the bell for the end of the 4th period rings to immediately start on lunch. While he rarely shows anger due to his mild temperament, food-related grudges are the exception. When his hunger reaches its limit, his sense of taste fails, and everything around him looks like food, causing him to attack indiscriminately.

Height: 170cm, Blood Type: A. Member of the Kimengumi. First person: I (casual/masculine). Known as "Buck-Toothed Kiyoshi." Characterized by a pointed head and narrow eyes. It is difficult to read his expressions, though his eyes become normal when he is surprised. His nickname comes from his prominent buck teeth. His hair stands up in the shape of the kanji for "mountain." He excels in Health and Physical Education (specifically regarding the female anatomy). He serves as the brain of the Kimengumi. While considered the least attractive member, he is the most socially aware and sensible. He is a lecher and weak for women, but he takes pride in his lecherousness and even holds "lewdness lectures" for the members (where he insists on not being vulgar). His special skill is skirt-flipping. It was mentioned that he once disguised himself as the school doctor during female physical examinations. He falls in love easily and is the type to devote himself entirely to the woman he likes.

Blood Type: B, Height: 168cm, Weight: 50kg. Member of the Kimengumi. First person: I (soft/polite). Known as "Pouty-Mouth Dai." Characterized by connected eyebrows and upturned eyes. Because he failed middle school twice, he is 18 years old as a high school freshman. He is effeminate and stands out even among the eccentric members. He has a girly personality and is prone to tears, fainting at the slightest thing, yet he can also show surprising courage when facing delinquents. Furthermore, he looks for any excuse to take off his clothes. His sex appeal is such that even men are sometimes inadvertently attracted to him. He is on good terms with the female students. His speech is not entirely feminine, nor is it the stereotypical "okama" style; it is more gender-neutral. On Valentine's Day, he joins the other members in wanting to receive chocolates rather than give them.
