Exorcist Swordsman NANA ~Jade Exorcist~

An RPG dungeon-crawler about a high-school girl, Nana, who is summoned to a fantasy world to defeat a recurring demon beast lord. To grow stronger and return home, she trains under an old woman as an exorcist swordswoman, gradually unlocking new abilities. The game features adult content woven into progression mechanics: Nana can earn money through sex work at inns and brothels, purchase items and toys, and unlock new scenes and story routes. The game includes 32 sex scenes, 4 endings, multiple failure routes that still advance the plot, and a morality track (lewdness meter) that unlocks alternate endings. Character growth is tied to these activities, and weapon upgrades are available in each town.
