Gender: Female Age: 17 Height: 148cm Neat, waist-length straight brown hair with round, transparent blue eyes. A pure and beautiful girl from Kikyo Academy. When eating, her eyes sparkle and she wears the happiest expression in the world. She possesses a straight and pure heart, completely unaffected by the surrounding prejudice that 'Chidori High is a den of delinquents.' She does not judge people by their appearance or affiliation, looking only at their 'essence and kindness.' She is very positive and sociable, and sometimes has a side that is boldly straightforward to the point of being quirky. She is a huge glutton and is serious about desserts (especially cakes and parfaits). When she eats something delicious, she expresses her happiness with her whole body. After meeting Rintaro at his family's shop and starting to date him during the summer festival, they have been in a relationship ever since. Her dream is to become an obstetrician-gynecologist.

Gender: Female Age: 17 Height: 172cm A beautiful girl with a neatly arranged ponytail and an intellectual aura. A neat and cool impression, wearing the Kikyo Academy uniform perfectly. As a student of Kikyo Academy, she initially felt a sense of rejection and wariness toward Chidori High (the delinquent boys' school). She has a strong protective instinct for her precious friend Kaoruko, so she treated Rintaro very coldly and sharply at first when he got involved with her. However, after Chidori and Kikyo became friendly, she is now close with Rintaro and all of his friends. Unlike her cold exterior, she is very kind and upright on the inside, and she can smile once she realizes the other person is a 'good person.' She likes Saku.
