The Kazegami Clinic rarely slept.
Machines hummed constantly, like distant insects trapped behind glass walls. Medical monitors blinked rhythmically in the darkness, marking the fragile line between life and death.
For most doctors, this place was routine.
For Yuna, it was something else entirely.
The clinic allowed Kaito to conduct discreet Neural Drift sessions on patients who had no hope of recovery. Families who consented believed their loved ones' final memories might be preserved.
In truth, Kaito was listening for something deeper.
The echoes.
And tonight, something was wrong.
Yuna stood beside the patient's bed.
A thin man lay motionless beneath the medical lights. His heart monitor flickered weakly. The neural interface crown rested over his temples.
Normally, Yuna only assisted.
She stabilized emotional fields while Kaito performed the deeper synchronization.
But tonight Kaito had stepped out briefly to recalibrate equipment.
So Yuna attempted the shallow sync alone.
She gently placed her hand against the neural interface panel.
The machine pulsed. Her eyes closed.
For a moment, everything was quiet.
Then— A whisper pierced the silence.
"Inugami… Hollow…"
The voice wasn't calm memory.
It was panic.
Fragments of thought flooded her mind.
Dogs. Teeth.
Blood on wet soil.
And a man smiling while everything burned.
"The dogs…"
The whisper trembled.
"The man… who smiles… before killing…"
Yuna gasped and tore her hand away.
The neural interface shut down with a sharp tone.
Her breathing became shallow.
Even though she rarely reacted to emotional overload, this memory had forced itself through the filter.
She clutched her small music box tightly against her chest.
The melody inside it began playing softly.
But the whisper wouldn't leave her mind.
Hours later, Yuna sat beside the window in the clinic dormitory.
Rain tapped gently against the glass.
She opened her sketchbook.
Her pencil moved slowly across the page.
A man with painted lips.
A smile stretched too wide.
Behind him stood dozens of dogs.
Their eyes were empty circles of glass.
When Kaito returned, she silently pushed the drawing toward him.
He studied it carefully.
His expression didn't change.
But inside his mind, something clicked.
"The man who smiles before killing…"
He whispered the phrase slowly.
"Not a metaphor."
He looked up at Yuna.
"It's a signature."
She nodded quietly.
Kaito closed the sketchbook.
Without another word, he began packing equipment.
The neuro-sync player. Mask skin overlays. Resonance probes.
Coordinates appeared on the navigation screen.
Destination: Inugami Hollow.
The train ride into the mountains felt like descending into another world.
Fog pressed against the windows like pale hands.
Villages became smaller. Lights grew dimmer.
Eventually the train stopped at a station that barely looked operational.
Kaito stepped off with a small travel case.
Yuna walked beside him silently.
A half-burned bus stop waited at the edge of the road.
And beneath its rusted shelter stood a man holding a rifle.
Detective Kyohei Aomine.
He studied Kaito carefully.
"You're late."
Kaito tilted his head slightly.
"You were expecting someone?"
Kyohei didn't smile.
"Someone strange was coming to investigate the Hollow. A man who doesn't exist in any police database."
He pointed toward the forest.
"Congratulations."
"You're him."
At first Kyohei didn't trust him.
When Kaito began talking about resonance bleed and neurological imprint instability, the detective's patience thinned quickly.
"You're telling me ghosts talk to you through brain waves?"
Kaito replied calmly.
"Not ghosts."
"Residual neural signals."
Kyohei sighed heavily.
"Same difference."
Still, something about Kaito's calm precision felt real.
Finally Kyohei pulled a USB drive from his pocket.
"You want proof something's wrong here?"
He handed it to Kaito.
They watched the lighthouse footage together on a portable screen.
Shiro Enma stood on the rocks.
Dogs surrounding him like soldiers.
Kyohei rubbed his temples.
"The violence isn't the worst part."
He paused the video. "Watch the rhythm."
The dogs attacked in perfect coordination.
Each movement timed. Each strike deliberate.
Kyohei muttered bitterly.
"He doesn't just kill."
"He stages it."
"Like a damn opera."
Kaito's eyes narrowed.
"Then it's not madness."
"It's conditioning."
That night, the Enma estate hosted its annual Birthday Carnival.
A grotesque parody of joy.
Fire breathers danced beneath lanterns.
Victorian jesters wandered the gardens.
Children hired from nearby towns laughed on command.
And through it all walked a man dressed as an eccentric street magician.
Kaito.
His pendant contained a hidden neuro-scanner.
He blended easily into the chaos.
Soon enough, Shiro Enma noticed him.
Shiro approached wearing elaborate taiko warrior armor.
His grin was theatrical.
"A stranger with secrets!"
He clapped his hands excitedly.
"Oh how delightful!"
He leaned close to Kaito.
"What trick will you perform tonight?"
His eyes sparkled dangerously.
"Will you pull my sins from a hat like a rabbit?"
They spoke privately in a mirrored greenhouse.
Red lanterns cast distorted reflections across the glass.
Shiro slowly plucked petals from a black chrysanthemum.
His voice softened.
"I was just a boy when I found my first beast."
He smiled faintly.
"I tried to love it."
"But the world laughed."
Another petal fell.
"So I taught the laugh to bite."
Kaito remained silent.
Inside his pendant, the scanner began detecting abnormal brain patterns.
Shiro's neural signals spiked wildly.
Not typical psychopathy.
Not sociopathy either.
Something far stranger.
Emotional circuits firing in unnatural patterns.
Like memories had been rewritten.
Kaito had seen this pattern once before.
In Yuna.
Suddenly the pendant emitted a sharp chirp.
High frequency. Barely audible to humans.
But outside— The dogs heard it.
Growling erupted across the estate.
Shiro's eyes lit up with excitement.
"Ah!"
He clapped happily.
"The orchestra begins!"
Chaos exploded through the carnival.
Outside the estate, Kyohei activated stolen dog whistle disruptors.
Metal spheres rolled across the ground.
They emitted conflicting command frequencies.
The attack dogs staggered, confused.
Snarling at invisible orders.
Kaito tossed decoy masks into the forest.
Pulse emitters activated.
False scent trails scattered everywhere.
Above them, from a tower balcony, Shiro watched with childlike fascination.
His smile widened.
"Beautiful chaos."
Later, inside an abandoned radio station beneath the hills, Kaito studied the collected data.
Yuna sat beside him quietly.
Screens filled the room.
Brain scans.
Video footage.
Old government archives.
Finally one keyword surfaced from a corrupted server. Project KUROINU.
Kaito froze.
Slowly, he opened the sealed files.
Subject Files: Shiro Enma – Subject Zero
Early-stage limbic remapping.
Trauma-induced emotional restructuring.
Neural desensitization.
Psychological weapon prototype.
Kaito's heart sank.
Then he opened another file.
Subject Two – Yuna
Mirror neuron suppression.
Empathy resistance.
Emotional field immunity.
Status: Trial Failure. Escaped.
The project's full title appeared on screen.
KUROI NUKE Initiative – Black Dog Program
Goal: Create trauma-resistant operatives capable of manipulating emotional environments.
Kaito leaned back slowly.
"Shiro wasn't born a killer."
"He was engineered."
Yuna quietly pushed another drawing across the table.
Three figures stood before a dark forest.
A magician. A detective. A small girl.
Facing them was a man with a crown made of teeth.
Kaito whispered softly.
"Project Kuroinu wasn't shut down."
His eyes darkened.
"It just put on a mask."
And somewhere deep in Inugami Hollow…
Shiro Enma laughed in the fog.
Because the final act of his play had only just begun.
