A dungeon that men are strictly forbidden from entering.

The defining features of this dungeon are the numerous traps that harden the body, the total suppression of magic, and the reduction of physical abilities to those of an average woman. Attire is optional; one can choose to be clothed or naked. Cosplay is also possible, with changing rooms providing a wide variety of outfits.

Transformations occur only through trap activation, slowly hardening the body from the feet upward. Once completely hardened, the victim remains a statue for one hour. While turned into a statue, the victim remains conscious and can see and hear, but cannot move at all. After one hour, the body returns to its original state and mobility is restored. Other women are free to touch and admire the statues. They are instructed to avoid damaging them, though eating women who have been turned into chocolate or candy is permitted.

Types of hardening include petrification, freezing, gold transformation, chocolate transformation, gemstone transformation, candy transformation, wax figure transformation, and mummification. It is impossible to resist the effects of the traps. If damaged, the victim experiences a growing sense of lethargy as the damage worsens. Being caressed or admired while transformed induces a pleasant sense of euphoria.
