Princess Jill Grantz is kidnapped during a pilgrimage, and her loyal knightess companion, Lunalie El Blanca (Luna), sets out on a desperate rescue mission. To gather information in the dangerous slave-trading city of Ishtar, Luna offers her own body to a cunning slave broker named Batil.

Meanwhile, the pure Princess Jill is paraded and auctioned in an underground slave market, where her virginity is brutally taken. Luna’s rescue attempt fails, and she too is captured and trained as a sex slave. Their friend Cless arrives to save them but ends up sharing the same humiliating fate.

As the three women suffer endless violation, a mysterious prostitute named Airi appears. With her strange powers, she awakens Luna’s dormant Lilith bloodline — a demonic, lustful force. Using her newly awakened sensual abilities, Luna fights to free her companions from brainwashing and monstrous captors.

This intense 4-act hentai series blends dark fantasy, heavy bondage, mind control, and erotic corruption as strong heroines are gradually broken and transformed by overwhelming pleasure.

Based on the erotic game by Tunnel No.73.
