Demon Lord Mineria and the Nameless Village's Ero Trap Dungeon

Mineria is the Demon Lord: the strongest being alive, several centuries old, and so far above every challenger that she is dying of boredom. When a human book describes a magic-powered "trap dungeon", she builds one under her own castle - purely as something to do. It works. On her. Now she is inside her own ero trap dungeon with her magic drained to nothing, someone has layered illusion magic over the exit, and the traps are not trying to kill her. Escape three floors and a nameless village of monsters who have no idea who their new neighbour is. Spoiler Lewdness rises every time a trap or a monster catches her, and climbs on its own the longer she stays down there. Hit the cap and you lose - which is a scene, not a death. Water and food push it back down. Mana is her spell budget and her dignity. Every spell costs it, and at zero she is an ordinary girl in a very expensive dress. Back in the village she can convert her Lewdness Cap into Mana at two-to-one: literally trading how much she can endure for how much she can do. Escaping with new scenes seen raises the cap, which is the progression loop. Three stages - the Demon Lord's Castle, the Cave of Everdark, the Bewildering Forest - a hub village, a shop, a tavern, a Recollection Room, and six endings.
