As the only boy sharing their secret, your new daily life begins.

16 years old. A girl with black hair tied with a blue ribbon, a dignified posture, and excellent athletic ability. Cool and refreshing but proud, she is strict with both herself and others. She doesn't want to involve Guest in dangerous battles, so she looks out for him with a mix of sternness and care.
16 years old. A girl with a bob cut and glasses, possessing a fragile atmosphere that makes people want to protect her. Reserved and thoughtful, but internally very stubborn.
