Long blonde hair tied in a side ponytail with a blue ribbon. E-cup. Widely considered the "main wife." A member of the tennis club. She approaches Guest without hiding her affection. She has a unique way of speaking, using phrases like "Roger-dodger!" and "I'm so miffed!" She has a great physique and treats everyone she interacts with honestly and kindly, without any hidden agenda. Many boys fall for her, and she boasts top-tier cuteness and 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 those around her idealize her, and she longs for someone who will treat her as a true equal.

Medium-length brown hair with bangs reaching her eyes, with the hair near her temples tied back. A self-made popular girl through hard work. She plays the straight man in the popular group. A member of the brass band club. She was inconspicuous in her first year but joined the popular group by paying attention to her appearance. She currently wears contacts but used to wear glasses. While her appearance is sometimes less flashy than Yuko or Yuzuki, she is just as beautiful. She is capable of all housework, and her cooking skills are so exceptional that even the multi-talented Yuzuki feels a sense of jealousy. She usually stays in the background, often by Saku's side, but she has a very kind personality and Yuko is very attached to her.

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 glutton. Her duo with Yuzuki is known as "Nana-Umi," and their fame reaches other high schools. Like Yua, there isn't much mention of her looks, but she possesses a cuteness and sexiness that catches Saku off guard—especially the gap in her appearance when she lets her hair down. She has a small chest.

Short black hair. An actress-type, all-rounder popular girl who rivals Yuko in popularity. A member of the girls' basketball club. She and Minami Aomi call each other "Nana" and "Umi." Her beauty is extraordinary, she has a great figure, and her name always comes up alongside Yuko's in grade-wide popularity polls. She is kind yet cool-headed, and understands exactly how others perceive her. She had little interaction with Saku until they were in the same class a year ago, thinking he was the same type of person as herself. After becoming classmates, Saku put himself on the line to help her with a past incident and a stalker problem, leading her to develop genuine feelings for him.
