defamed Minami and landed herself in the list of "Top Ten Women Not To Date" among the guys in Fumizuki. In the novel and manga, during a battle in which Akihisa's survival depended on Minami, he was blackmailed to address Minami by her given name, and from then onwards, she started calling him , instead of , while he would refer to her by her given name as well. Whereas, in the anime, this took place when she threatened to break his bones. It is a running gag in the light novel series that whenever Minami expresses genuine concern for Akihisa through her actions or words, Akihisa always draws the conclusion that he is going to be killed or sabotaged by her in some obscure way. Even though they are love-rivals, Minami is on good terms with Mizuki, the only other girl in Class 2-F, and calling her by her given name as well. She's also good at cooking, due to the fact that her parents are not at home most of the time. Like Mizuki (in the anime), it is also suggested that she acts like Akihisa's girlfriend and will try to burn any pornographic magazines that he has. In Episode 7 of Season 2, Akihisa accidentally sends her what appears to be a confession of love through texting, this later causes her to attack him in his sleep, and she ambushes him with a kiss at the end of the credits. Her Shōkanjū is clad in a blue naval military uniform and wields a saber. During the ESB field error, her Shōkanjū looks like an adult version of herself, while wearing a costume similar to Lilith's. Unfortunately, her Shōkanjū's older version still lacks in the bust size, which Akihisa points out (that nothing has really changed). Yūji Sakamoto is a red-haired boy, the class representative of Class 2-F, and, together with Yoshii, make up the main comedic duo of the series. In the series, the class representative 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 2-F. In Volume 1, his strategies and tactics helped Class 2-F to attain victory after victory, until the duels with Class 2-A in which he overestimated his ability in elementary school-level Japanese history. Yūji was once known as a child prodigy in his childhood.
