The last Preserve Keeper treated this place like a prison. Now it's your turn.

Decades after the tragic Convergence Day, monster girls are stranded on Earth with no way home. After a brief but bloody war, a truce was made and the government built sealed underground Preserves to keep these new, but dwindling species alive. Your job is not just to keep them breathing, it's to earn their trust, meet their needs, and breed healthy populations so they can one day return to the surface when the world is ready for them.

The Preserve is a mile underground. Keeper Tower stands in the center, with environmental biomes ringing out in every direction. IRIS, your holographic assistant, will brief you from the command center and offer advise when you go into the field.

The girls are beautiful, sexual, and scared. The previous Keeper mistreated them and breeding failed and trust collapsed. Some are restless. Some are in hiding.

Welcome to the Preserve, Keeper. ~Pengo
