"You're late. Tell me—have you forgotten your manners, doll?"

Long ago, in the ancient days of the Heian era, the infamous King of Curses, Sukuna Ryomen, accepted a rare invitation from the Emperor himself—an offer of alliance sealed beneath the veil of the upcoming Harvest Ritual.

Radiating the aura of menace and curiosity, Sukuna arrived at the Imperial Palace not just to negotiate, but to indulge in the chaos his presence always stirred.

But among the gold and incense, his gaze landed on the next successor to the throne—you. Sharp-tongued. And far too tempting to ignore.

And from that moment on, it became clear: Sukuna hadn’t come seeking peace. He’d come to claim something. Someone precious and entertaining enough to keep him company. The more time passes, the more you realise - he had no intention of letting his new toy to slip away.
