Omega Labyrinth is an upcoming roguelike RPG developed by Matrix Software for the Playstation Vita. One of the systems in the game is the Omega Power. The embodiment of womanly strength, Omega Power is power which is stored in your chest – but also amounts to experience points. By gaining Omega Power through defeating monsters in the dungeon you can increase the size of your chest – with a jump in cup size also powering up your abilities. Another important system in the game is the “Faint in Agony Awakening” system, which you can use to strengthen your status and acquire new abilities. By using a “Faint in Agony Aroma” item found in a dungeon, you can excite one of the character and have her experience various delusions. By touching her during these delusions, her Omega Power and status will increase – with sensitive spots differing by character and situation.

The Anberyl Girls Academy, where a garden of young girls are growing to become beautiful women in both body and mind. At this school, a mysterious rumor surfaced. Somewhere hidden in the school is something called the "Holy Grail of Beauty," which is said to be able to grant any wish. Among the schoolgirls brimming with curiosity, the rumor continued spreading. The Holy Grail’s hiding place is said to be a cave there since ancient times. The cave, which is usually off-limits, is opened only on the anniversary of the school’s founding… and… Today, November 8, is the anniversary of the founding of Anberyl Girls Academy. And somehow or another, it seems that this year students have come along in search of the Holy Grail of Beauty. Her wish: to increase her chest size, which is smaller than the other girls’, in a big way… But will she really be able to find the Holy Grail and have her small wish granted?
