Mandatory Mentor

Mandatory Mentor is a 3DCG visual novel where you play a tutor tasked with preparing Reina, a spoiled and bratty student, for the University of Tokyo entrance exam. Stranded on a deserted tropical island for seven days with no distractions, your success means returning to civilization—failure condemns you both to permanent exile. The game features fully voiced dialogue, multiple endings, and a stat-management system where every choice in meals, lessons, and discipline shapes Reina's performance. A second playthrough mode, "Survival," introduces stat decay that demands careful resource management to prevent total failure.
