Maou Kourin ~Onna Yuusha Shojo Ryoujoku~

Become the fearsome devil king who terrorizes so many kingdoms in popular JRPG games -- only this time you're assaulting them in a conquest-driven ADV + SIM style!

Expand your evil empire across the realm, taking down the 3 main characters of female hero, female mage and female warrior - but also map-wandering mercenaries, elves, shrine maidens and village girl minor characters.
