"Double NTR"—perhaps this twisted genre has its own charm?
A chaotic and erotic story is about to begin.

A year has passed since the tragic world-spanning war between the Demon King’s army and humanity.
In the town of Spenia, royal orders have assigned a "Defense Mission."
The object of protection: a mysterious artifact known only as the "Treasure."
No one knows its purpose—but the Demon King will stop at nothing to obtain it.

"The Lionel family, a prestigious lineage of mages, has been tasked with guarding it.
Among them, Leo, the least talented member, shoulders a heavy responsibility, leading his comrades in the defense mission."
This is the story of those final few weeks.

You are a hero summoned to another world who, after defeating the Demon Lord and the Evil God under the Goddess’s guidance, travels to her most devout city to report your victory. Instead of a holy sanctuary, you find the population has vanished, replaced entirely by beautiful, seductive women. The entire city is sealed by a powerful spell that traps you inside, and a curse strips you of the ability to use violence against women, leaving you defenseless.

To escape, you must reach the throne at the castle—the source of the spell and curse. The women offer information and items in exchange for draining your experience levels, but this comes with lethal risk: if your level falls too low and your partner is higher-level, you will be drained to death on the spot. Each death triggers an automatic time rewind, reviving you to try again.
Armed only with persistence and the ability to retry endlessly, you must carefully negotiate, endure repeated level drains, and piece together clues to navigate the city and break the curse—all while resisting the women’s draining advances in this perilous, seductive trap.
