Polys of RiYu is a story-driven adult visual novel that throws players into a mysterious parallel world through a fractured dimensional brane. You play as an ordinary working adult whose self-driving car crosses the rift and deposits you on the outskirts of a capital city where you speak no language, hold no currency, and quickly become the focus of local authorities and a research institute. Polys of RiYu blends narrative exploration, character-driven choices and worldbuilding as you learn the language and history of this society where men are rare, and every decision reshapes relationships and outcomes across branching story paths.
