Adult PC Game: Studio Paper Waifu - Infinite Desires: Anadira Sasha v1.1.5 Archive

The world takes place in a fictional version of Earth where multiple dimensions exists. In a small corner of the world, these dimensions all converge into a melting pot, allowing lifeforms from different dimensions to coexist in harmony. The "Infinity Dimension" as the Earthbounders and the representatives of other dimensional beings coined it, is beyond the rift, and both exists and does not exist at the same time in its little place on Earth.
