"Monster Girl Quest: Paradox RPG is based off the highly-popular Monster Girl Quest series of visual novels. In this spin-off, the characters and events of the original visual novel series are noticeably altered from their original timeline counterparts. Luka (the main series protagonist) is thrown into an adventure to discover the reason for his father's disappearance, the meaning behind the mysterious message of the Goddess Ilias, and to delve deep into the inexplicably-appearing chasms known as "Tartarus Pits". Accompanying him are his childhood friend Sonya, the Monster Lord/Goddess Ilias, and a variety of companions from the story itself!"

-Experience an engaging and unique story set in the Monster Girl Quest universe!
-Choose your own class, race, weapons, etc in a unique rpg system!

How will it all end?"
