As Earth-san leveled up, everyday life was dyed into fantasy.
Dungeons and monsters appeared, and the karma status system was released for many creatures.
The petite girl Hitsujiya Meiko, who celebrated it like the other creatures from all over the world, was swallowed by the appearance of a dungeon infested with monsters.
