Hitoyoshi Castle
When Park Seong-jin reached Hitoyoshi Castle, he deliberately delayed his approach by one more day.
It was his usual way.
First, look at the people.
Only then, look at the castle.
A castle does not run away.
Tongues do.
Hitoyoshi Castle stood on a natural fortress formed where the Kuma Rivermet a tributary known as the Fierce River—also called the Chest River.
The bend where the waters merged shaped the land itself into a defense.
These rivers were not merely waterways.
The Kuma River carried a heavy volume year-round, swift and deep.
The Fierce River, when rain fell, swelled in an instant and swallowed the ground beneath the castle walls.
There was no need to dig artificial moats.
The water itself was a blade encircling the stronghold, draining an enemy's momentum before they ever crossed.
To the north and west, the Kuma River and its branches sealed off all approach.
Without boats, access was impossible.
The castle did not simply rise from a flat plain.
Steep ridges stacked like steps, platforms layered one upon another.
From below, it looked like a single fortress.
Once inside, another fortress appeared.
Climb again, and yet another platform blocked the way.
The spacing between these levels was exact—
not too far, not too close.
Attackers found no time to catch their breath.
Defenders could calmly rain arrows and stones.
The Honmaru, the main keep, sat at the highest point, commanding a full view of the castle town below.
Houses lining the Kuma River, the port, kitchen smoke curling upward, the faint outlines of fields—everything lay exposed.
Standing there, it became clear: this castle was not merely a defense.
It was an eye.
Along the earthen ramparts remained a peculiar stonework known as musha-gaeshi—"warrior repeller."
The outward-tilting stone walls were no ornament.
Ladders slipped.
Bare hands were flung outward the moment weight was applied.
Each stone was calculated, its surface deliberately roughened to deny even a fingerhold.
The east and south were no weaker.
Below one embankment lay another, then stonework again.
The instant an intruder crossed a single layer, every blind spot vanished.
Arrows, stones, boiling water, logs—everything could pour down at once.
Those who climbed were always exposed.
Those who defended were always above.
Hitoyoshi Castle was special not merely because it was strong.
For nearly seven hundred years—from the Kamakura period to the end of the Edo shogunate—the Sagara clanruled this land.
The reason lay here, fully embodied in terrain and masonry.
This was not a castle rebuilt with each era.
It felt like a living thing shaped alongside nature.
Water became moats.
Hills became walls.
Stone became hands that pushed invaders away.
Thus Hitoyoshi Castle stood—
a completed form of defense forged over centuries by rivers, earth, and human desire.
Below, where the Kuma River curved gently, lay the castle town.
The river was not wide, but deep, and unusually clear.
Clear water meant few people upstream—and also that this land had long escaped the heavy hand of constant military or administrative exploitation.
The port was small.
No large vessels.
Only shallow-draft boats moving along the riverbed.
Rice sacks, salt, dried fish passed through.
No weapons.
That absence was suspicious.
If you cannot see something, it is often because it has been hidden.
Park Seong-jin entered the town dressed even more raggedly than before.
His sword was wrapped in cloth and slung across his back.
His outer robe was dust-stained.
At a glance, a drifter.
He entered an inn.
The innkeeper first avoided his gaze, then widened his eyes briefly at the hint of a Goryeo accent—
and said nothing.
People here had learned not to ask.
Not asking was how one lived long.
He ordered a bowl of liquor and a bowl of soup and opened his ears.
"They say these ones live off piracy too."
The innkeeper's wife replied,
"That's old talk. These days some madman's been hunting pirates… no one dares move."
"Boats move on the river at night," Park Seong-jin said.
"What are those?"
"How would I know? They only move after dark."
Hitoyoshi was far from the sea.
It did not look like a pirate stronghold.
That was precisely its strength.
Loot taken from the sea could be hidden inland, exchanged for rice and people, then sent back out.
Boats moving upriver traveled only at night.
Park Seong-jin left the inn.
A brewery.
A blacksmith.
A shabby teahouse at the edge of the market.
Everywhere, the same words.
"The lord doesn't know."
"He pretends not to."
"Nothing moves without approval from above."
By the second day, he was certain.
They had joined as well.
The Sagara clan had ruled too long.
Longevity meant knowing how to survive.
And such families usually excelled at keeping their hands clean.
Hitoyoshi did not wield the blade directly.
It coordinated from behind—gathering people, opening routes, siphoning rice.
Its hands looked clean.
Which made it worse.
That night, Park Seong-jin went to the lower reaches of the Kuma River.
No moon.
Mist hung low over the water.
Three small boats were moving upstream.
No oars.
They slid, reading the current.
Familiar hands.
Park Seong-jin stepped onto the water.
The ripples were small.
His foot barely pressed the surface, and he was already beside the first boat.
They claimed they were not pirates.
As he turned away—
A blade came from behind.
Two men.
He lowered his waist and cut horizontally.
Thud—thud.
They collapsed against the gunwale without a sound.
The second boat.
Three men.
One held a spear, its tip shaking—fear came first.
Park Seong-jin did not draw his sword.
A knife-hand crushed the neck.
Arms flung bodies aside.
Vital points pressed.
They fell silently.
The third boat held crates.
Inside—rice, iron fittings, and Goryeo-style arrowheads.
Willow-leaf shaped.
He closed the crate.
Tied the boat to shore.
Checked the knot once more.
Then he looked up.
Not at the river.
At the castle.
It was not that the water led to the castle—
the castle sat atop the waterway itself.
This was no longer suspicion.
It was confirmation.
He headed for the castle.
This was not a matter of tongues.
It was time to drag down hands that had never dirtied themselves.
Hitoyoshi Castle.
Low.
No towering tenshu.
Earthen embankments and layered stonework.
Not a castle of display, but one that knew how to endure.
It did not rise upward.
It sank inward.
The guards at the gate were lax.
Lax not from carelessness, but from habit—
the habit of living long under the protection of river and bend.
Park Seong-jin walked straight to the main gate.
"Halt."
He spoke his name.
"Goryeo Army. Middle Commander Park Seong-jin."
The guards laughed at first.
Laughter always comes first—
not mockery, but relief.
A way to push away what one does not want to believe.
Then the laughter vanished.
The rumors had already arrived.
"…How did you get here?"
"I came to deliver a message. To your lord."
The gate did not close.
It opened—hurriedly.
The sound was too loud.
Not wood opening, but minds.
From that moment, the air inside the castle changed.
No people visible—only presence.
Breath held.
Bodies pressed behind doors and walls.
Then sounds surged together.
Archers running atop the gate tower.
Wood thudding under their feet.
Geta clattering—samurai.
Spearmen barking orders.
It was expected.
But—
They had not decided.
"They've come."
"Stop him."
That single command had scraped soldiers together.
To them, stop himmeant die.
Park Seong-jin walked slowly.
One step.
Two.
Not from hesitation.
Walking slowly let the enemy collapse more clearly.
The gate beneath the tower tore open.
Samurai poured out.
Armor clattered.
Some hadn't even fixed their helmets.
Some clutched swords with eyes already gone.
Archers lined the ramparts.
Arrow slits—barely wide enough for an eye—filled with bows.
A breath.
No signal.
Arrows fell.
Air split.
Feathers trembled.
Earth burst.
Shields cracked.
Hitoyoshi's castle was low—but its shooting angles were not.
The ground before the gate became a valley of death.
Park Seong-jin did not lower his body.
He raised an arm and flicked his wrist.
Several arrows twisted off course and fell.
Some struck their own.
Men froze, clutching their throats.
That was the castle's first defeat.
Spearmen surged.
A wave.
Park Seong-jin stepped forward—
Half a step.
Just half.
And the ground responded.
The soil sank—layered clay and sand.
His foot caught.
Just for a moment.
That single moment was what the castle had been waiting for.
Arrows came low this time—sideways.
Spears thrust together.
Yes. A complete defense.
He acknowledged it—
And ended it.
He shifted his weight into the sinking ground.
Lowered his center.
Twisted.
Not a light step.
A step that broke the earth.
The formation cracked.
He pushed, not cut.
Shafts split.
Men collided.
The line collapsed.
His blade slid sideways, then up.
Underarms.
Waists.
Throats.
Where movement slowed.
Bodies fell.
Blood slicked the ground.
Arrows ceased—no angle left.
They understood then.
This was not a castle's fight.
It was a man's fight.
And that man was one.
By the time silence fell, only breathing remained.
He did not kill them all.
He broke arms.
Crushed legs.
Shattered shoulders.
He took away swords forever.
Before the main hall, the lord knelt.
"I did not know."
"You knew."
"We did not act directly."
"That is why your sin is deeper."
Documents lay stacked behind him.
Ships.
Rice.
Names.
Park Seong-jin burned them.
Sometimes killing roads is better than killing people.
"Today, it ends."
The lord understood.
Park Seong-jin kicked a sword toward him.
The man tried to stab himself.
Failed.
Hands shaking.
Park Seong-jin pressed unseen force.
No pain.
Before dawn, he left.
The gates stood open.
Behind him, Hitoyoshi Castle burned.
The town woke as if nothing had happened.
Only eyes had changed.
He crossed the Kuma River.
The water was still clear.
Hitoyoshi fell silent.
And Park Seong-jin did not look back.
Another name had already risen in his mind.
