In Front of the Hospital - During the night time,
The night was calm, the fluorescent lamps outside the Nakano Hospital were buzzing faintly as they lit the front courtyard.
A chilly wind brushed against the flagpole, rustling the cloth banner with a hollow whisper.
Through the iron gates came a young man in a security guard's uniform, yawning so wide he nearly dropped his lunchbox.
His name was Tanaka Haruto—a freshly hired guard, still in training under his senior.
Tanaka rubbed at his messy hair and muttered to himself,
"Man, night shifts are killing me. If I didn't need the paycheck, I'd still be in bed right now…"
Dragging his feet across the paved walkway, he finally reached the small security booth at the hospital entrance.
The dim light inside revealed another guard slumped over the desk, face hidden under his cap.
Tanaka gave a crooked grin, as he said.
"Oi, Boss, don't sleep here. You'll catch a cold. I'm here to take over—go home already."
Silence—
The booth was quiet, eerily so. No snoring, no grumbling.
Just silence.
Tanaka blinked. His senior was usually a light sleeper. Even the sound of a pencil rolling off the desk could wake him up. Suddenly, a strange chill ran down his spine.
"...Boss?" he called again, voice lower this time.
No response.
Feeling uneasy, Tanaka buttoned the last strap of his vest and stepped closer. He reached out and tapped the man's shoulder.
"Boss, hey. Are you okay?"
Still nothing.
Tanaka swallowed nervously, then bent down to shake him awake. But when he pulled the older guard's body upright—
"AHHHH!"
A terrified scream ripped from Tanaka's throat.
What stared back at him was not the familiar, honest face of his senior.
Instead, the man's ears had twisted into elongated, demon-like points, and his jaw was stretched unnaturally wide, exposing a row of sharp, beastly teeth. His skin suddenly turn pale and clammy, veins dark like ink crawling under the flesh.
Suddenly, the creature sucked in a ragged breath—
"HHAAHH—"
—and snapped his eyes open.
Most of the eyeball was drowned in black sclera, leaving only a glowing, pinprick-white pupil fixed on Tanaka.
"Bo-Boss…?" Tanaka stammered, stumbling back, heart pounding wildly.
His senior—NO! That thing's lips curled, baring those inhuman teeth. Its voice came out distorted, layered with an echo, as though several people spoke at once:
"Oh, It's Tanaka-kun."
The creature stood up slowly, joints cracking unnaturally as it rotated its stiff neck. Its presence was overwhelming, like a suffocating malice that can any person tremble in fear, despair, helplessness.
In its head, new thoughts swirled—memories belonging to the human security guard whose body it had taken over.
This "senior" no longer existed. Only the demon remained.
It flexed its hands, long nails hardening into knife-like claws, and muttered with something close to amusement:
"... Meat… blood… I want them…"
Tanaka backed into the corner, trembling, eyes wide in panic.
His instincts screamed at him to run — Run as fast as he could.
The demon turned its hollow gaze toward him, its voice oddly calm:
"Tanaka-kun, come here. I have something to tell you."
"D-don't!" Tanaka blurted out, shaking his head violently.
No way in hell. He might have been naive, but he wasn't stupid. A man who looked like a monster asking him to "come closer"? That was nothing but a death sentence.
His legs gave out under him, but adrenaline surged. He pushed the booth door open, intent on bolting into the night.
But....he never made it outside.
In an instant, something seized his neck—an iron grip that cut off his breath.
"Ghh—ahhh-" Tanaka choked, kicking helplessly as his body was lifted into the air with one hand, his eyes rolled back, as if he could lost his consciousness at any moment.
The demon grinned, saliva glistening on its teeth. Its eyes gleamed with the wild hunger of a predator savoring its prey.
"Tanaka-kun… you smell delicious."
The sharp teeth opened wide, ready to tear into his throat.
And then Suddenly—
"Oh? I get to witness this kind of scene right away? That's kind of interesting… Demon."
The words were casual, almost amused could be heard.
Both Tanaka and the demon froze.
The voice hadn't come from within the booth, but from outside, leaning lazily against the wall near the hospital gate.
The demon turned its head.
Standing there, illuminated by the flickering fluorescent lamp, was a man with messy white hair, a tall and lean frame, and a black blindfold covering his eyes. His lips curved in a playful smirk as though this whole bloody sight was nothing more than entertainment.
It was Gojo fucking Saturo.
The moment it show him, demon's instincts screamed in alarm. This man was no ordinary human. The sheer aura radiating from him was suffocating.
Danger. Danger. Danger.
Panicked thoughts rushed through its mind —
Run. Flee. Escape.
But deep down it knew, Instinctively — the gap in strength was too wide. An inferior demon like it could never escape from his hands.
Unless… it could summoned someone.
A wicked grin twisted across its face. Black energy began to seep from its pores like smoke.
Dark markings crawled over its cheeks, grotesque horns sprouted from its temples, and its nails extended further, glinting like blades under the dim light.
Its entire form warped — transforming into a more monstrous state.
"Hahahaha—" the demon laugh, as it raising a clawed hand. Without hesitation, it stabbed the blade-like fingers through its own chest.
The sound was sickening—flesh ripping, bone cracking—yet instead of falling, the demon's aura only grew heavier, more sinister. The ground quivered faintly as the surge of demonic energy spread outward.
Gojo tilted his head, unimpressed,
"Wow. You guys really love your dramatic transformations. Very theatrical. Points for effort, though."
Despite the madness unfolding before him, Gojo's tone was relaxed, as though he were judging a school play rather than watching a demon mutilate itself. His blindfold hid his eyes, but the amused curl of his lips made it clear—he wasn't even remotely concerned.
For him, this wasn't a crisis.
It was entertainment.
The demon, however, roared with bloodlust, its voice rumbling like an animal's growl. It hunched forward, claws scraping against the booth walls, ready to leap at Gojo.
Tanaka, forgotten for the moment, collapsed to the floor coughing violently, clutching his bruised neck. He scrambled back toward the corner, eyes never leaving the monster that had once been his senior.
He didn't understand what was happening. All he knew was that the white-haired man outside—the one smiling so casually—was the only reason he could survive.
And the reason — Gojo however was stretching his arms lazily as though preparing for a nap, as he murmured:
"Well then… let's see what kind of demon you are. Don't disappoint me too much, alright?"
