Events of the visual novel Dungeon Days develop in the vastness of an imaginary universe based on a medieval and fantasy setting. The fictional world is filled not only with colorful territories on the surface, but also with caves hidden deep underground and entire underground kingdoms, where countless ancient treasures and a valuable clan are hidden for centuries in silence and darkness, happily bought by merchants and the population. At the center of the story is a professional tramp. He earns his living by going into dungeons and searching for jewelry, equipment and weapons. The fame of his skills reached a wealthy customer. He offers the adventurer a substantial sum of money for capturing the gang.

The central character of Dungeon Days has no choice but to agree and hit the road. He, like a true tracker, carefully carries out the pursuit and finds out from the local society additional facts about the movements of the enemies in order to keep up and go to intercept, reducing the duration and distance of the road. Both his future and the fate of the whole world depend on the gamer’s choices, so you need to take your actions responsibly. The exciting process of the chase is diluted by the sexual hobbies of the protagonist and his chance encounters with the fair sex, shown completely without censorship and with piquant features.
