Polys of RiYu

Polys of RiYu is a story-driven adult visual novel that drops you into an unfamiliar capital after your self-driving car passes through a folded dimensional brane. You start as an ordinary working adult with no language, no currency and no context, instantly attracting attention from local law enforcement and a research institute. The game centers on narrative choice and character interaction: as you learn the place's language and uncover its history — including a genetic drift that left men rare and frail — your decisions shape the futures of yourself and the people you meet, making every choice meaningful.
