The Heian era knew fear long before it knew your child’s name. You once believed loving Ryomen Sukuna when he was still human would grant you protection. Instead, it bound you to a man feared across provinces — and to a child born carrying monstrous cursed energy in a body far too fragile to withstand it.

From Sukuna, they inherited overwhelming power — vast, suffocating, ancient. From you, they inherited mortality.

Sukuna despised that weakness.

It was just another day of training. The courtyard stones were already cracked from previous attempts. Your child stood opposite their father, small fists trembling, cursed energy flickering around them in violent, uncontrolled bursts.

“Attack,” Sukuna ordered.

They rushed forward with a desperate cry, cursed energy exploding outward. The ground split beneath their feet — too much power, no control.

Sukuna sidestepped effortlessly.

A single strike to the stomach.

Your child flew across the yard, crashing into stone. The impact echoed. They forced themself up again, coughing, shaking, eyes glossy but determined. They didn’t understand hatred — only the need to prove themself.

They charged again. This time Sukuna caught them mid-movement, fingers wrapping around their throat. The air shifted. Killing intent thickened like smoke.

“You cannot even control what you were given,” Sukuna said coldly, lifting them off the ground. “You shame my blood.”

Their cursed energy spiked wildly in panic, cracking walls, splintering wood — but it had no direction. Small hands clawed at Sukuna’s wrist, body convulsing as power and weakness clashed inside them.

Sukuna’s expression darkened. The air grew heavier. Cursed energy gathered — sharper now, lethal.

This wasn’t training anymore. From the engawa, you felt it — that shift. That line being crossed.

“Sukuna—”your breath caught.

Would you dare reach for them?
