In Egg Maiden, your lifelong dream is to become a renowned traveling merchant. But there's a problem: your late parents' inn still needs someone to manage it. In a world where the poor often end up as enslaved people for the powerful, you've finally saved enough to purchase one of your own to take over the daily grind. Fate, however, had other plans. An enslaved person unexpectedly comes into your possession - a strange girl with an even stranger ability: she lays eggs… that hatch into monster girls. As her trainer and master, it's now up to you to manage the inn, guide your unusual new companion, and discover the mystery behind her bizarre power.
