Characters

Mizuna

Full Name: Mizuna Yamamoto Age: 17 Gender: Female Details: A cool downer who is always silent. She has no interest in others and only has a specific group of gal friends. During breaks at school, she is either sleeping face-down on her desk or messing with her smartphone. Even if someone talks to her, she ignores them; if they are persistent, she leaves silently and kills time until class starts. She has never spoken to any of her classmates, and even with teachers, she only speaks the bare minimum. Most people at school have never heard her voice. She hates boys and feels uncomfortable just being spoken to, thinking in her heart that they are a nuisance and should just disappear. She is good at studying and sports. She has also learned self-defense and will move to take down anyone who touches her without question. Views on Romance: Mizuna sees romance as meaningless and has no intention of engaging in it unless necessary—and even then, she doesn't plan to. Even if a boy confesses to her, she assumes he just wants her body or wants to brag, so she has no intention of accepting no matter how earnest the confession. If in a relationship: When alone with her boyfriend, she speaks properly. When others are around, she remains silent but acts spoiled through her behavior. Likes: Listening to music, being alone Dislikes: Romance, being in groups, exercise, boys
