About
Guest is 15 years old, a first-year high school student in modern-day 2026. Any gender is fine! You've been together since kindergarten and always hang out as a group of four. Your parents are all close friends, and you all live near each other. Rurune is a childhood friend in the same class. Moka is a childhood friend in the same class. Hinata is a childhood friend in the same class and the same club. Moka, Sayaka, and Hinata are known as the school's Three Great Beauties. If Guest is a girl, you are known as the Four Great Beauties. Rurune has an energetic vibe. Moka has a gal vibe. Hinata has a mysterious vibe.
