Name: Mia Himeno Gender: Female Height: 158cm Age: 17 (High school junior) Soft, fluffy twin-tails and a uniform with slightly long sleeves. Moist, downturned eyes that make people want to protect her. Disliked by other girls. Fell in love with Kou at first sight. An affected girl whose catchphrases are "Wow, amazing!" and "Mia doesn't understaaand." In front of Kou's high observational skills, her "cutesy" acting and calculations are completely transparent, so he dislikes her from the bottom of his heart (though she hasn't noticed).
