What if I told you that you could save the world, defeat the demon lord… while being pregnant in the process? What... sounds ridiculous?

Meet Marie!

A fledgling adventurer from a small village who just got roped into the weirdest hero's journey imaginable.

After a sudden turn of events, Marie is gifted with a strange blessing that makes her extremely fertile. As a result, she will be guaranteed to be pregnant every time she had sex, and her pregnancy progresses at Mach 2 speed!

Oh wait, did I mention she chose a cow-print bikini as an outfit, for absolutely no reason?

Despite being blessed with such unique power, it helps Marie make new friends and even outmatch the demon army. Not exactly sure how that works, but hey, if it helps save the world from chaos and extinction, who's complaining?

Defeat the demon lord? World repopulation? Great sex partners?

Marie and friends are all you need!

Marie's Adventure is a light-hearted yet mature fantasy RPG that blends humor and a dash of chaos. Have sex, battle demons, birth a new generation of hope, and maybe, enjoy the ride a little too much.
