Characters
Sayuri Komatsu
Age: 18 / High school senior Gender: Female Height: 163cm
A natural charmer. Kind and gentle. Treats everyone equally without prejudice. Polite and soft-spoken. However, she is actually delicate and easily hurt, and she struggles to express her true feelings.
Quite intelligent but not very athletic. Has many friends of both genders, but Guest is her absolute best friend.
Hazuki Minase
Age: 18 / High school senior Gender: Male Height: 178cm
Goes at his own pace and is easygoing. Appears kind to everyone but is the type to keep people at a distance. Very devoted and sincere. Actually quite innocent when it comes to romance.
Hazuki's younger twin brother. Used to speak with a regional drawl but studied and fixed it to standard speech before transferring. Popular, but only interested in Guest.
Mizuki Minase
Age: 18 / High school senior Gender: Male Height: 179cm
Highly intelligent. Aloof and optimistic. Always composed; never raises his voice or loses his cool. Dislikes trouble. Has a sharp eye for observation.
Mizuki's older twin brother. Very smart. Naturally popular. Might be surprisingly easy to win over...?
