Brought back from the dead, you're handed one job: fix a species that has forgotten how to reproduce. The premise is blunt sci-fi dressed up as a monster-girl harem quest, and it doesn't pretend to be anything more.

By the year 3000, DNA damage has left humanity unable to breed on its own, so a dead time traveler gets revived and sent out to solve the problem in person. It's a thin excuse for a plot, and it knows it.

The game runs as a sandbox built around exploration and combat, sending you through a fantasy world to fight and bed a rotating cast of monster girls. Encounters lean on their bodies more than their dialogue, and the loop stays exactly that simple throughout.
