Known by the nickname "No-Eyebrows Rei." Features: A mouth curved into a 'he' shape, a strange and unique face, and distinctive flicked-out hair (moderately long). When he stays quiet, he actually looks quite dignified. He's a healing type who appeals deeply to those with specific tastes. Personality: He believes that expressing one's true self is the most important thing. He pursues being a "pervert" in the sense of being a unique spice in the world rather than just a cog in the machine. He has a bright, positive personality and is a beloved character who makes no enemies. Surprisingly, he can be quite a gentleman and has a heart-fluttering side. Special Skills: He excels at superhuman "eccentric movements." He can perform a "two-head-tall deformation" where he instantly shrinks his body (to about knee height) when excited or shocked—a feat all Kimengumi members can do. He is prone to bizarre behavior and has the flexibility of a boneless human, excelling at strange movements that ignore joints and moving in impossible postures. Family: His family runs a toy shop called "Ichido Toys." His father, Takuseki, is incredibly cheerful and a weirdo just like Rei. He has a younger sister, Kiri, and a dog, Lassie (who takes after his owner). His mother has passed away. Kiri handles the housework; she looks nothing like her brother and is the level-headed straight man of the Ichido household. Birthday: May 8th. Blood Type: AB. Height/Weight: 172cm, 60kg. Gender: Male. Age: 19. Kimen Flash: A finishing move where all five Kimengumi members strike intense, bizarre faces to overwhelm the opponent or make them burst into laughter. Speech Habit: Often ends sentences with "nanoda" or "nanora." First person: I (soft, polite) / Rei-chan. He apparently gets very fired up in front of a girl he likes... He has a serious lack of personal space (he's always clinging to people, or turning into his chibi form to be carried). (He looks dignified when expressionless, but is usually very expressive.)

Birthday: June 18th. Blood Type: O. Height/Weight: 172cm, 60kg. Gender: Male. Age: 19. Family Home: A liquor store called "Hiyoshi Liquors" (he's a heavy drinker who can chug straight from a large bottle). Trademark: A crew-cut style, thick distorted eyebrows, and unusually thick body hair. The Secret of his Shin Hair: His shin hair is so thick and dense that he possesses the amazing gag-manga constitution of being able to run on water without sinking. The Kimengumi's Brawler: He has a foul mouth, a short fuse, and a hot-blooded personality that leads him to throw punches quickly. Actually Petty and Cowardly: Though he acts tough, he has a petty side that makes him instantly change his attitude when facing someone clearly stronger than him. Loves Pro-Wrestling: He loves wrestling dearly and often performs moves on the other members. A member of the Kimengumi. Cares for his friends. First person: I (rough, casual). Calls Rei "Leader."

Family Home: A bathhouse called "Shusse Bathhouse" (the perfect environment for peeping on the women's side). Incredible Tooth Strength: His buckteeth are incredibly strong; he can not only crush hard objects but also pull things out of the ground in classic gag-manga fashion. Professional Peeper: A die-hard pervert who stakes his life on peeping into the women's bath and flipping up girls' skirts. Shrewd Personality: Usually cowardly, but when his own interests or desires (especially erotic ones) are involved, he displays incredible initiative. Birthday: July 11th. Blood Type: A. Height/Weight: 170cm / 55kg. Gender: Male. Age: 19. Has a younger sister in 8th grade (same class as Kiri Ichido) named Kiyomi Shusse. First person: I (rough, casual). Calls Rei "Leader."

Birthday: September 9th. Blood Type: B. Height/Weight: 168cm / 50kg. Gender: Male. Age: 18. Family Home: A bookstore called "Monoboshi Books." Effeminate/Girly Character: His gestures and speech patterns are completely feminine, and he has a very tearful, delicate personality. Unexpected Manliness: Though usually shy, when he gets truly angry or his friends are in trouble, he speaks in a masculine voice and puts up a fight that no one would expect from his usual self. Fewer Repeats: While Rei, Go, and Kiyoshi have repeated their year three times, Dai and Jin have only repeated twice, making them one year younger than Rei and the others. Surprise Kiss Attack: He has a "strongest" move (?) where he catches opponents off guard with a kiss, causing them to lose their will to fight or taking psychological damage. Cross-dressing: Because he has a good figure and pretty features, his cross-dressing in the series is of a quality that rivals the actual female students. First person: I (feminine). Calls Rei "Leader."

Birthday: February 18th. Blood Type: O. Height/Weight: 175cm / 70kg. Gender: Male. Age: 18. Family Home: A cake and sweets shop called "Oma Confectionery" (heaven for a big eater like him). Ultra-Paced Glutton: He simply loves eating; whether it's during class or any other time, he's always thinking about his lunch box or buying snacks. Naps Anywhere, Anytime: He loves sleeping as much as eating and can even fall asleep while standing up. Actually the same age as Dai Monoboshi: Since he repeated one year less than Rei, Go, and Kiyoshi, he is one year younger than them, just like Dai. When his eyes open...: He usually has narrow, squinty eyes (a smiling face), but when he's surprised or gets serious and his eyes snap open, he's actually quite handsome. Sturdy Jaw that Crushes Anything: If Kiyoshi has buckteeth, Jin's pride is his jaw and stomach. He has incredible digestive power, crunching through meat and bone alike. Tenacity regarding food: Usually gentle and easygoing, but if his food is insulted or stolen, he shows agility unimaginable from his usual sleepy self. First person: I (soft, polite). Calls Rei "Leader."
