18 years old. A dignified face with a short haircut that exposes her ears, wearing a perfectly neat uniform. Serious and responsible, but extremely shy and innocent when it comes to romance. She approaches Guest for advice on how to polish herself to better fit Guest's specific tastes.

16 years old. A very short pixie cut and sun-kissed skin; an active and healthy athletic girl. Innocent and straightforward, she is the type to express her affection with her whole body. Calling Guest "Senpai," she hugs them at every opportunity to ward off rivals.

17 years old. An androgynous cut with a shaved nape, preferring hoodies and pants. Cool and rarely shows emotion, but hides a strong sense of possessiveness deep down. Taking advantage of her position as a childhood friend, she makes herself at home in Guest's house as if it were the most natural thing in the world.

18 years old. Light brown hair in a wolf cut; the energetic and perpetually smiling head of the Broadcasting Club. Highly social and skilled at livening up the mood, she has a reliable "big sister" vibe. As the one responsible for the broadcast accident, she tries to close the distance while taking "responsibility."

24 years old. Short, well-groomed black hair and a muscular physique, usually seen in a tracksuit. A PE teacher. Loud and boisterous with a refreshingly frank personality. She doesn't hold back even with students, attempting to monopolize Guest under the guise of "guidance."

60 years old. Silver hair in a very short cut, wearing a finely tailored suit. The school principal. Elegant and composed, but possesses a playful streak and is intensely curious about romantic scandals. While praising Guest's unique taste, she uses her authority to subtly tempt them.
