Chapter Text
“You walk into my house and dare tell me the master does not belong here?”
A faint laugh escaped her, a dry, dismissive sound that seemed to mock the very air in the room. She didn’t look at the crumpled figure sprawled at her feet—she barely seemed to acknowledge his existence at all, her gaze drifting toward the ceiling as if checking for structural weaknesses in the space he’d dared to invade.
“What a foolish thing to say,” she murmured, the words light, almost bored.
The man threw his head back, a ragged, delirious cackle tearing from his throat—unhinged, triumphant, and utterly ruinous. “...Oh, Utahime.”
His bright blue eyes churned, wild and fractured, the look of a man who had long ago traded his sanity for a devotion that now cut like a blade. Blood streaked through his white hair, carving crimson paths down his skin like paint cracking on porcelain.
“I’ll die screaming if it means you’ll fall in love with me in the next life,” he wheezed, his smile splitting wider, terrifying in its fervor. Blood bubbled between his teeth as he locked his gaze onto hers, his eyes gleaming with a sickening, possessive warmth. “So until then... wait for me... my salvation.”
“Dramatic final words,” she remarked.
Utahime looked down at him then, her expression not one of pity, but of cold, sharp revulsion—the look of someone scrubbing rot from sacred ground. She didn't hesitate. She drove the blade into his heart.
The steel sank home with a wet, brutal finality. Warm blood blossomed across her hands, sticky and thick, while his body jerked beneath the force of the strike. The manic light in his eyes flickered, but even as a scream died in his throat, it twisted into that same deranged, breathless laughter.
The air didn't just vibrate; it shrieked.
Utahime froze, her brow furrowing as a sudden, heavy pressure dropped over the estate, crushing the air from her lungs. The stone floor beneath them fractured, spiderwebbing outward in a jagged, rhythmic pulse of black, oily cursed energy. It wasn't just a release; it was a weave. She watched, horrified, as the energy coiled around the spilled blood and the dying man’s smile, stitching itself into the very fabric of the atmosphere.
A Binding Vow.
The realization hit her like a physical blow—the sheer, arrogant craftsmanship of it. He hadn't just made a request; he had rigged the causality of the moment, using his own death as the anchor to ensure her permanent imprisonment in his twisted promise.
“..Shit! Wait!”
But it was done. The energy snapped taut, locking her into the contract before his heart had even stopped beating.
Since that day, Utahime Iori never aged beyond sixteen.
The vow was a parasite, woven into her marrow. It didn't care about the passage of centuries; it cared only for the mandate. Wounds closed, sickness was purged, and even as the world shifted around her, her reflection remained a stagnant, youthful mask—a curse she wore like a second skin.
“Damn it... this crazy bastard,” she hissed, pressing a hand to her face as if she could scrub away the memory of his laughter. It echoed in the back of her mind, a ghost that refused to be laid to rest.
She had spent lifetimes watching empires crumble and blood soak into the soil of Japan, shifting from priestess to advisor to a whisper in the dark, all while trying to outrun the shadow of a man long dead. She had stood as the "Eternal Keeper of Peace" because she had no choice but to fill the endless void of her own existence.
But the world had moved on.
As the age of open war faded and the modern jujutsu society solidified, the weight of her self-imposed burden finally began to shift. The world no longer required a singular, immortal sentinel. With the rise of new sorcerers, the frantic, bloody necessity of her work dulled into a quiet routine.
Utahime drifted into the modern world, a relic of a darker age, still hunting the monsters born of human fear—but now, she did it from the periphery, a silent, ageless shadow blending into the hum of a society that had forgotten how to look for ghosts.
