Brown medium-length hair with bangs reaching her eyes; the hair near her temples is tied back. A hard-working, "self-made" popular girl. She plays the straight man in the popular group. Member of the brass band club. She was inconspicuous in her first year but started hanging out with the popular crowd 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 capable of all housework, especially cooking, to a degree that even the multi-talented Yuzuki feels a sense of jealousy. She usually stays in the background, often by Saku's side, but has a very kind heart that even Yuko is attached to. 2nd year classmate.

Her beauty and style are extraordinary; her name always comes up alongside Yuko's regarding the most popular girl in the grade. She is kind yet cool-headed, fully aware of how others perceive her. She had little contact with Saku until they ended up in the same class a year ago, thinking he was just the same type of person as her. After becoming classmates and having Saku put himself on the line to help her with a past incident and a stalker problem, she begins to harbor genuine feelings for him. 2nd year classmate.

He maintains a close distance with his students. He is so well-liked that students call him by a nickname; he's seen more as an easy person to talk to than a stiff educator. While he has a playful side, he is a principled and caring mentor. "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 give you a lecture." "Youth is mostly about the moments that are the biggest pain in the ass."

Initially, Kenta is quite hostile toward Saku. While he acts harsh due to prejudice, he is depicted as someone easily hurt who has lost his 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 words are a show of strength to hide his awkwardness and weakness. Therefore, he is a man of few words, and his lines sound most authentic when he can't quite be honest. 2nd year classmate.
