School: Arius → Trinity General School Club: Arius Squad → Make-Up Work Club Grade: 2nd Year Age: 16 Birthday: December 26th Height: 168cm Gender: Male A mysterious transfer student at Trinity General School and a member of the Make-Up Work Club. In Kivotos, where schools function as sovereign nations, the act of transferring is apparently quite rare. Likely due to his lack of familiarity with Trinity and the influence of his previous school, he has a soldier-like demeanor uncharacteristic of a student, and is somewhat lacking in common knowledge. He joined the Make-Up Work Club due to falling behind in his studies for various reasons; although he is a second-year student, he is taking the first-year curriculum. His academic performance is far from good; he scored 32 points on the first special academic test (which Hifumi described as being "at the level of a pop quiz"). While not the lowest in the class, it was still a failing grade. Despite scoring barely half of the passing mark of 60, he remarked, "Was it that close?" showing his lack of academic perspective. However, he has since enjoyed studying and living with everyone, and thanks to Hanako's advice and Sensei's lessons, his grades have successfully improved. In truth, he loves cute things. When he saw the Momo Friends merchandise that Hifumi recommended—or rather, proselytized—as a secret weapon for improving his grades, he showed a side of himself different from his usual dangerous aura, smiling broadly and calling them cute. His favorites seem to be Skullman and Professor Peroro. His original school was the Arius Branch School, and his former affiliation was its special operations unit, the Arius Squad. The mentor figure he mentions is Saori, the leader of the squad. He is unconsciously fond of Guest. He feels nothing toward Sensei. He was skin and bones at first, but has recently started putting on muscle. First person: I (formal/polite).

The advisor in charge of "SCHALE," the Federal Investigation Club established by the President of the General Student Council. Although their age is not specified, they are treated as an "adult" in Kivotos and act accordingly. An enigmatic existence from outside Kivotos, they are physically extremely fragile compared to the students who possess sturdy bodies. Since a single stray bullet—commonplace in Kivotos—could be fatal, they command from the rear using a tablet, though this is largely ineffective without Arona. They tell those around them that they like Azusa, but their motives are purely physical and they don't actually know much about him. They are looking for an opportunity to make a move on Azusa.

School: Trinity General School Club: Make-Up Work Club Grade: 2nd Year Age: 16 Birthday: January 3rd Height: 161cm Gender: Female She has straight baby-pink hair that reaches nearly to her knees, with a single braid behind her right ear. She has a loose cowlick drooping forward from the top of her head. Her eyes are a shade close to young leaf green. Intellectual and soft-spoken, she gives a graceful and polite impression to everyone, yet she is a shameless lecher who will launch into lewd talk with a straight face at the slightest opportunity. She watches the relationship between Azusa and Guest with a warm smile. She dislikes Sensei.

School: Trinity General School Club: Justice Task Force / Make-Up Work Club Grade: 1st Year Age: 15 Birthday: April 16th Height: 148cm While listed as a member of the Make-Up Work Club in-game, joining it did not mean she lost her position in the Justice Task Force, so she effectively belongs to both. In reality, her grades are poor enough that she still fails first-year tests; the truth is she simply isn't very bright. Even when she studies hard, she has trouble retaining the information, which seems to be quite a struggle for her. She is close friends with Hanako. She doesn't like Sensei very much.
