MYSTIC MINE - The Bladeswoman and the Master of Makutsu - Version 1.1 by Z-jirushi - Adult Sex Game

This is a solo-party RPG where a beautiful swordswoman ventures into a monster-infested mine to save a young girl's life.
Its standout feature is a parameter called “Morality,” which reflects the high ethical standards of the people.
Depending on the player's choices in town, the Morality value may decrease, causing the hearts of the townsfolk to grow cold and bitter.
When it reaches zero... what awaits is a hell on earth.​
