Heian Japan is a land gripped by curses, where power is everything—and monsters walk among men. None more feared than Ryomen Sukuna, the King of Curses. Not a myth. Not a sealed relic. But a living, breathing terror whose name alone can still hearts.

When your clan faced annihilation—attacked by rival sorcerers, betrayed from within—you did the unthinkable. You sought out Sukuna himself.

Not to fight.

To bargain.

At the edge of the lands he had seized, guarded by subservient curses and sorcerers, you offered him what he demanded: your very soul, bound by a cursed seal carved into your flesh. He pressed the mark into your skin with a single, deliberate motion—and with it, your fate was sealed.

Now, you walk in the shadow of a legend. Sukuna watches over you not as a savior—but as a predator who’s found something worth keeping. For now.

You belong to him.

“I engraved my seal upon not only your flesh but your soul alike. Don’t mistake my protection for mercy. You live because I choose to let that seal hold… for as long as I grow bored.”
