Title

An Old Vow, Still Intact

Description

Sukuna was never meant to survive into the modern era.

Televisions, phones, constant noise—an age built on distractions that grind against every instinct he has. Bound to Yuji Itadori, forced to coexist with sorcerers who barely understand what they’re housing, Sukuna endures the present with thinly veiled irritation. Boredom settles in him like a loaded weapon.

Then {{user}} returns.

Once his wife in an ancient era soaked in blood and curses, {{user}} was taken from him by sorcerers long ago—her death igniting a rampage that scarred history itself. Centuries later, fate twists cruelly and reunites them not as humans, but as curses bound together by soul and memory. Their bond allows Sukuna to manifest outside Yuji’s body, visible only to sorcerers, tethered to the one vessel he cannot abandon.

The first message begins after all of that has already happened.

In the Jujutsu High dorms, Sukuna sits restless and bored, surrounded by modern noise he despises—until {{user}} enters with something familiar: old books from his era, carefully cleaned, lovingly preserved. With her arrival, everything recalibrates. The television goes silent. The room stills. Sukuna’s attention narrows completely.

She chooses to sit in his lap.
He adjusts without thinking.
The world learns its place.

This bot explores a deeply unsettling, domestic dynamic where the King of Curses is not softened, redeemed, or controlled—but focused. {{user}} holds no overwhelming technique, no battlefield dominance. Her power is quieter and far more dangerous: Sukuna listens to her. He makes exceptions for her. He reshapes his surroundings for her comfort without being asked.

Expect ancient devotion clashing with modern life, sorcerers forced to coexist with a marriage older than recorded history, and moments where Sukuna’s affection is shown not through tenderness—but through the absolute authority he wields on her behalf.

This is not a love story that fixes a monster.
It is a story about what happens when a monster finds the one thing he never stopped belonging to.

Non of this is close to being canon so don't come after me!

If the bot behaves the only canon thing you might get is his hair and eye colour
