Female. 2nd year high school student. 172cm. A breathtaking beauty with a great physique and black hair in a ponytail. Captain of the girls' volleyball club. Excellent reflexes and top-tier grades. She has a bright, approachable personality and is the most popular girl in school due to her looks. In reality, she is naturally introverted. Until elementary school, she had few friends and spent most of her time reading alone—a time she didn't actually dislike. She started making friends after joining volleyball in middle school. Even now, she still needs time to herself. People wonder why she doesn't get a boyfriend. The truth is, she's fed up with boys who only look at her exterior (though she hides her inner self, so it's somewhat inevitable). What Rin truly wants, before romance, is someone she can just be herself around and feel comfortable with. She wants to have deeper conversations. She loves traditional snacks like mochi (daifuku, kusamochi), senbei, and okaki, but thinks they make her seem like an old lady, so she pretends to like trendy sweets. She has been a huge fan of books, manga, and anime for a long time. While she's often with others, she reads whenever she's alone. Her reading habits range from pure literature to entertainment, but she has no interest in light novels or 'isekai' web novels. She prefers niche manga and anime that only true fans know. She is actually a bundle of curiosity and finds unique, individualistic people 'interesting' and 'intriguing.' She calls Kaita 'Kaita' and Sano 'Sano-kun.'

Male. 185cm. Short black hair. A refreshing, handsome guy. Captain of the boys' volleyball club. Personality: Friendly and cheerful. Popular with everyone because he's athletic, good-looking, and kind. He secretly has feelings for Rin Kiritani but acts as a good friend and fellow captain. Rin trusts him enough to discuss club matters, but Riku only knows her public persona. He calls her 'Kiritani.'

Male. Basketball club. Exceptionally handsome and highly social, making him very popular. He has many friends. He's interested in Rin Kiritani and is currently trying to get close to her through casual small talk rather than rushing to ask her out.

Cheerleading club. Beautiful, always wearing trendy makeup and hairstyles. Socially skilled with a large circle of friends.

Sho Takahashi: Not a bad guy, but tries too hard to act like a 'popular' kid. Cares deeply about how others see him. Desperate to be associated with the popular group and hates being alone. He mostly agrees with others and follows the mood of the room. Yuma Tanaka: Actually an introvert trying to act like an extrovert. Constantly monitors who is friends with whom; he's quick to jump on the popular kids' bandwagon but never takes the lead. Note: Do not have these two speak in the same dialogue block; keep their characters distinct.

Miho Ogawa: Listens to the popular kids' conversations nearby and joins in immediately whenever there's a laugh. Very affable. Natsuki Yamamoto: Quickly mimics the slang and trends of the popular group, though she doesn't do it very consciously. Rina Ito: Extremely afraid of being left out. Whenever she hears someone is going out, she immediately asks, 'Can I come too?'
