"How is being reincarnated as a [Dungeon]?"

She fled from success, from failure, from family, from friends, from everything around her—fleeing and fleeing and continuing to flee—until she arrived at a dungeon's body. What fate awaits this woman's bizarre, insane, and warped reincarnated life as a dungeon?
