The skies over Japan looked peaceful.
People moved about their daily lives—children laughed in the parks, office workers hurried to their jobs, and students complained about their homework. The world seemed normal… too normal.
But behind that calm surface, a hidden truth existed.
A secret organization—Hunter Intelligence Agency (HIA)—operated in the shadows.
They were unseen protectors.
And their enemies… were not human.
Demons.
Four years ago.
The city of Fukushima became the stage of a tragedy that would never be forgotten—at least, not by those who knew the truth.
To the world, it was nothing more than a nuclear leak incident.
But the reality… was far more terrifying.
"All units! Evacuate the citizens of Fukushima immediately!"
The command echoed through streets already drowning in panic.
Black smoke rose into the sky.
Buildings collapsed one after another.
People ran aimlessly—some crying, others screaming in fear.
And in the middle of that chaos… something stood.
Something not human.
The creature was massive, its body wrapped in a pulsing dark aura like a living heartbeat. Its eyes glowed crimson, and each step it took made the ground tremble.
Rajau.
A high-threat demon.
A monster that brought destruction.
HIA Headquarters – Tokyo
A massive screen displayed the live situation in Fukushima.
"Rajau is rampaging. Threat level has risen to Red Category!"
An operator spoke with a tense voice.
A man stood before the screen, calm—but his eyes were sharp.
Commander Takahashi Edo.
"Has… he arrived?" Edo asked quietly.
A moment of silence.
Then—
"Commander! We've received a message… he's on the way."
Another agent swallowed nervously.
"…No, wait—"
"Commander… he's already here."
Back in Fukushima—
A massive explosion shook the entire area.
BOOM!
The shockwave swept everything away—glass shattered, vehicles flipped, and dust filled the air.
HIA agents on-site struggled to hold their ground.
"All units, maintain formation!"
But their voices were nearly drowned out by destruction.
Suddenly—
One of them looked up at a crumbling building.
"Hey… look up there…"
Another followed his gaze.
His eyes widened.
At the top of a tall, cracked, smoke-covered building—
A man stood.
Calm.
As if the chaos meant nothing to him.
The wind gently moved his black hair.
His eyes were cold, sharp… and empty.
"No way…"
"That's… him…"
"Seiichi Asuka…"
"Special Grade."
Below, Rajau stopped moving.
The creature lifted its head.
Its eyes locked onto the figure above.
For the first time since the destruction began…
Rajau smiled.
"So… a worthy opponent has finally appeared."
Its dark aura surged violently, like hellfire erupting.
Buildings around it began to crack under the pressure alone.
On the rooftop—
Seiichi Asuka simply watched.
No emotion.
No words.
But inside his mind—
Calculations.
Distance.
Speed.
Angles of attack.
Every possibility analyzed in an instant.
He exhaled slowly.
"…annoying."
That was all he said.
In the blink of an eye—
He vanished.
An HIA agent gasped.
"He… disappeared?!"
The next second—
BOOOOM!!!
The ground in front of Rajau exploded.
Seiichi appeared right before the demon.
His first strike—
Faster than lightning.
The air split apart.
Rajau barely raised its arm—
CRASH!
A shockwave blasted through the surroundings.
The road shattered.
The sky trembled.
Rajau burst into laughter.
"Interesting! Very interesting!"
But…
That smile slowly faded.
Because in front of him—
Seiichi Asuka didn't move an inch.
Unaffected.
Unshaken.
Those cold eyes simply stared… as if observing something insignificant.
Back at Tokyo HQ, Edo closed his eyes.
"So… it begins."
And on that day—
The city of Fukushima was recorded as "destroyed" in the world's history.
But to HIA…
It was simply the day a legend was born.
To be continued…
