Height 154 cm Weight: 42 kg 2nd Grade highschool student in Fumizuki Gakuen. She's in the same F-class along with Akihisa and friends, but actually she is ranked 2nd from the whole school in academics. A gentle and well-behaved bishoujo. Though she is weak in health, body development is pretty okay, with an F-class bust size. She came to the F-class because she exited the room midway during the class division examinations- resulting in a zero score. She was Akihisa's first love since long ago when they were in elementary school, but never noticed until recently when he pleaded for her during the class division examinations. But why she likes Akihisa is the greatest mystery of the 21st century. It seems it has something to do with the rabbit-shaped hair decoration she likes. After the incident she tried several times to confess to Akihisa, but due to unfortunate circumstances she did not succeed. But when she is drunk or her emotions are stirred, her actions can cross the line. She is very smart but because of her innocent character, she believes in others' words too easily. She also does not have any love experience; and although she knows Akihisa is trying his best for her, she thinks it's just because he is kind. And she did not yet notice Minami's heart to Akihisa. She is neat and mature but easily become jealous. Influenced by Minami and the F-class, her punishment level of Akihisa's flirtatious(?) nature has grown recently. She cooks with images, not ingredients (ex: "Sour" -> "Vinegar" = "Acetic Acid") and therefore the taste of her food is the ultimate weapon that sends anyone who eats it to the underworld. However because she fears of the victim becoming her practice target and hides the truth, she does not her true capability. Her hobbies are sewing dolls and collecting photos of Akihisa in girls's outfits. She is very weak against alcohol, and easily gets drunk. When she's drunk, she gets bold. Because of her insensibility, she does not know of her appeal or her past records; thus not very confident in herself. Her Shoukanjuu's tools are western-styled armor and a large sword. Bracelet's special ability is "Heat rays". Occult version is Succubus, influenced from the feature "Boldness (in many meanings)" and "bust size".
Age: 16-17 Height: 162 cm Weight: 48 kg 2nd Grade high school student in Fumizuki Gakuen. In Class F. Friends with Akihisa since grade 1. Because of his silent and serene nature he is not often noticed, but for his perverted heart and how he is always trying to hide it, he was nicknamed "Muttsurini" (a parody of Mussolini, also said to be the shortened form of "Muttsuri Sukebe", meaning "Reticent Pervert"). Most of his grades are almost as low as those of Akihisa, but his knowledge of sex is unusually broad, so his grades in Health and Physical Education are unusually high. However, he has a tendency to have a nosebleed whenever he imagines or sees something suggestive. In some cases, he bleeds so much that he requires several packs of blood to maintain vitality. He is also known as "Voyeur" and "Pervert Ninja" in English translations.

Yuuji Sakamoto is the class representative of class F. In the series, the class rep position is assigned to the smartest student of that class. He is cool, collected, and exhibit surprisingly high intelligence and foresight unexpected of a student from class F. In volume 1, his strategies and tactics had helped class F to attain victory after victory, until the duels with class A in which he overestimated his ability in elementary school level Japanese history. Yuuji was once known as a child prodigy in his childhood. The only reason why he ended up in class F was because he did not study at all and he holds the strong belief that grades are not everything. However, due to the consequences he 'suffered' from his defeat from ShÅ�ko Kirishima, his childhood friend and also the top student of his level, he became motivated to study again, and in the later volumes, his Shoukanjuu became reasonably strong in just a few months due to his test scores improving by leaps and bounds. It is implied that he is actually smarter than his childhood friend, Shouko. After the tournament in volume 2, he acquired a platinum bracelet which allows him to control the size of the force field of his Shoukanjuu, allowing him to form a one-man army choke point since humans cannot pass through this force field. He bears no ill intention towards Shouko, but due to her unyielding obsession with marrying him since their childhood days, he sees her as having a few loose screws in her mind, and fears to even think of his future if he does marry her. In the anime, it’s suggested that they act like a married couple though she tends to treat him as a slave. Yuuji is close to Akihisa to the point where they can actually communicate without any words. A gag in the series is that Yuuji will attempt to decipher a complicated expression on Akihisa and comment on a series of events that must have taken place. While he meant it as a joke, he is always a spot-on when this happens. His Shoukanjuu wears an outfit that makes it look like a punk, and is armed with brass knuckles. (Source: Wikipedia)
