Omega Labyrinth

User Summary The game is set in the Anberyl Girls Academy, where a rumor of a "Holy Grail of Beauty (美の聖杯)", an object said to be able to grant any wish, has surfaced. It is said to be hidden in an ancient cave that is only open on the school's founding day. Thus, at the beginning of the game, several girls have come in search of the mysterious grail, with protagonist Aina Akemiya setting out to find the grail in order to increase her chest size, which is smaller than the other girls'.
