This is an RPG in which the protagonist—an excavator (whose name can be changed)—accepts a commission to explore an underground cemetery alongside a magical doll girl.

You develop your base by upgrading the facilities you’ve built and issuing orders to your allies to gather materials, while acquiring skills, upgrading weapons, and occasionally taking a bath or eating a meal as you conquer the dungeon.

You’ll be forced to expel the “impurity” accumulated in the dungeon through unsavory acts (paid) at the church, or compelled to engage in unsavory acts (paid) to replenish your depleted vitality— proceed through the game by repeating these actions. All of this is thoroughly recorded in your save data.
