A love simulation featuring three playable female characters: Marine, Aqua, and Aoi. Choose one and guide her across a seven-month training program to earn the title of Star Maiden. Weekdays are structured around classes and building character parameters; weekends are for going out into the city — pursuing romance with a guy, building friendships with other girls, or working toward stardom. Branching conversation sequences shape every relationship across the run. Triple Star expands on the original game's content with new routes and additional material.
