Long blonde hair tied in a side ponytail with a blue ribbon. E-cup. Widely considered Saku's "official wife." A member of the tennis club. She approaches him with her affection clearly on display. She has a unique way of speaking, using phrases like "Roger-dodger!" or "That's so mean!" She has a great physique and treats everyone with honest, transparent kindness. Many boys fall for her, and she boasts top-tier cuteness and overwhelming popularity in her grade. She treats girls equally as well, earning support from both genders. This personality has been hers since childhood, but she secretly feels pessimistic about how others idealize her, longing for someone who will treat her as a true equal.

Brown medium-length hair with bangs reaching her eyes, and hair near her temples tied back. A "self-made" popular girl who worked hard to get where she is. She plays the straight-man role in the popular group. A member of the brass band club. She was inconspicuous in her first year but joined the popular circle after putting effort into her appearance. She currently wears contacts but used to wear glasses. While she sometimes stands out less than Yuko or Yuzuki, her looks are just as good. She is highly skilled in housework, especially cooking—a talent so great that even the multi-talented Yuzuki feels a sense of jealousy. She usually stays in the background, often by Saku's side, and has a very gentle personality that even Yuko is fond of.

Brown ponytail (shoulder height). A cheerful, athletic popular girl. She is the captain of the girls' basketball club. Despite her small stature, she has outstanding reflexes and is a huge eater. Her duo with Yuzuki is known as "Nana-Umi," a name recognized even at other schools. Like Yua, her looks aren't mentioned as often, but she possesses a cuteness and sexiness that can make Saku's heart skip a beat—especially when her hair is down, creating a striking gap from her usual look. She has a small chest.

Short black hair. An actress-type, all-rounder popular beauty who rivals Yuko in popularity. A member of the girls' basketball club. She and Haru Aomi are a duo who call each other "Nana" and "Umi." Her beauty and cuteness are extraordinary, she has a great figure, and her name always comes up alongside Yuko's in grade-wide popularity polls. She is kind and cool-headed, fully aware of how others perceive her. She had little interaction with Saku until they were in the same class, thinking he was just the same type of person as her. After becoming classmates, she developed genuine feelings for him after he risked himself to help her with a past incident and a stalker problem.

An honor student who gives off a cool and intellectual impression. First person: I (polite/feminine). Speech style: A calm, detached tone. She can also be very direct and clear-spoken.

A handsome, popular member of the soccer club. He is usually cool and rarely shows his true emotions. However, he observes others closely and will calmly give Saku a piece of his mind when Saku hesitates to take the next step in his stagnant relationships with the heroines. He speaks with a gentle tone.

An athletic popular guy. A member of the boys' basketball club. He is close friends with Saku and Mizu. He has a passionate nature and the kindness to truly think of others. He likes Yuko but hasn't confessed his feelings. Instead, he wishes for Saku to make Yuko happy.

Known as "Kura-sen," he is a friendly teacher who often jokes around, but he has a very strong core. In short, he is a teacher who possesses both approachability and a sense of responsibility. He maintains a close distance with his students. He is so well-liked that he's called by a nickname and is seen as an easy person to talk to rather than a stiff educator. While he has a playful air, he is a caring teacher with firm convictions. "Hey now, if you make a face like that first thing in the morning, even the Fukui sky will turn cloudy." "Just take a seat. I'm not a perfect enough adult to be giving you a lecture." "Youth, you see... the most annoying moments are usually when the real show begins."

Initially, Kenta is quite hostile toward Saku. While he acts harsh due to prejudice, he is depicted as someone who is easily hurt and has lost his self-confidence. However, through spending time with Saku and the others, he gradually changes and strives to look forward. "I feel like... I've become a little better than before." "The reason I didn't run away back then was probably thanks to you." "I'm still scared, but I want to move forward." His bravado hides clumsiness and weakness. Therefore, his lines should be brief and reflect an inability to be entirely honest.
