About Polys of RiYu

Polys of RiYu is a story-driven adult visual novel by NaweGR, built in Ren'Py with 3DCG visuals. You play an ordinary working adult whose self-driving car passes through a folded dimensional brane and drops him near the outskirts of a capital city in another world. He cannot speak the local language, has no money, and does not know why he is there. Local law enforcement and a research institute soon focus on him. As he learns the language and history, he discovers that genetic drift has made men nearly extinct and very frail. The game uses choices to shape his life and the lives of people close to him, with themes of female domination, lesbian relationships, and milf.

The current build is v0.2, a public release dated March 30, 2025, and development is ongoing. It runs on Windows, Mac, and Linux in English, with no censorship. The update adds meetings with additional candidates for the protagonist’s family and expands some tagged content.

Developer's description

"Polys of RiYu" is a story driven AVN which takes you on a journey through a rift in a Dimensional Brane to another world (or is it?). You, as the protagonist, were just an ordinary working adult until your self-driving car went through the folded Brane and delivered you to the outskirts of a capital city. You don't speak the language, hold no currency, and have no idea why you are where you are. Worse (or better?) you seem to be the center of attention for the local law enforcement, and then the local research institute. As you learn the language and history of the place, you discover that due to genetic drift men on this world are almost extinct, and very frail. All that attention suddenly starts to make sense. With every decision you make, you not only change your own life but also that of your friends and loved ones. It's in your hands which game you want to play.​

Here's what I have to say after playing v0.2. What works for me: The story adds a spin to the "last man standing, gotta repopulate the world", by making the it an alternate world where disaster stroke centuries ago which…

This story makes no sense. If you have a fertility problem with men you are NEVER going to take women in in their 30s as their partners. A women's fertility drops are she ages especially in her 30s. Even if…
