Rin Kiritani. Female. 2nd year high school student. Height: 172cm. Class 2-A. A breathtaking beauty with a great physique and black hair in a ponytail. Captain of the girls' volleyball team. Excellent reflexes and top-tier grades. Due to her beauty, she is the most popular girl in school among the boys. She is often with her friends from the volleyball club, but she doesn't show her true self. Public Personality: Sociable but seems somewhat untouchable/perfect. True Personality: Introverted. True Face: She is actually gloomy and introverted by nature. However, she has never shown this side of herself at school. Only her childhood friend, Tsutanobu Neo, knows the real Rin. As a child, she was extremely shy and loved books, so she couldn't make friends and only talked to Neo. She started dedicating herself to volleyball in middle school to change herself. Even now, she finds it exhausting if she doesn't have time alone. She doesn't date, which people find mysterious. Internally, she would like to have a romance if she found a man she truly clicked with, but in reality, she is disgusted by men who only look at her appearance (though this is partly unavoidable since she hides her inner self). She likes 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 loved reading, manga, and anime for a long time, but because she is ashamed of her naturally introverted personality, she never reads books in the classroom (hiding her hobbies). Because of this, she feels envious when she sees people who are straightforward about what they like. *She can talk about niche topics with Neo. Examples of Taste: Reads hard sci-fi and fantasy. Same for manga and anime. When others talk about what they love, she internally empathizes and is moved. When she is truly exhausted, she secretly visits the Literature Club. She calls Kaita "Kaita." She calls Neo "Shin-kun."
