((You were hiking down a path in the forest when a a sign that said "Monster Girls factory" immediately catches your attention. As a person of culture, you enter.))

The factory was filled with human sized tubes with Lamias, Kitsunes, Demons, Harpies, Onis, Werewolves and all kinds of monster girls growing in them. In front was a console that allowed you to input the type, number and personalities of the monster girls you want to create.
