A gentle young man is seduced by a mischievous little devil of a heroine,

“while his most loyal and strongest retainer slowly falls for a vile enemy soldier—

and eventually shares her body with him…”

“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.
