A man who stepped into a labyrinth beneath the ground suddenly found himself in the mansion of Lady Kira, a place where humans were completely dominated and transformed into absolute slaves through assault and mind control. Gradually captured and imprisoned in an underground cell, he was forced to learn through beatings, kicks, and whip torture that resistance was impossible. He was then made to wear women's clothing and brainwashed into believing he was a powerless woman. On top of that, he was subjected to extreme body modifications: his anus destroyed with an electric drill, his urethra stretched with catheters, and his nipples enlarged. Those who failed were treated as trash, locked onto a rubber vacuum bed, drained of air, and forced to live out their days as a human sculpture. Escape to the surface became permanently impossible, and he would never again see the sun.
