Roronoa Zoro's mouth hung open in utter disbelief as he stared at the sparring match unfolding before him.
Commander Saint Roselith Seraphina versus Dojo Master Shimotsuki Kōshirō.
The training ground had long since lost its original shape.
Grass was shredded.
Earth was split.
Blade marks crisscrossed every visible surface like a violent tapestry carved by steel.
Even the air trembled.
Kuina's eyes remained locked on Seraphina.
"…She's a woman too…"
Her voice was barely a whisper.
Yet it carried the weight of something far deeper than surprise.
BOOM!!!
The clash of blades detonated like thunder.
Winter Solstice and Wado Ichimonji collided, their impact releasing a circular shockwave that rippled violently outward.
Dust spiraled.
Loose stones scattered.
Zoro's jaw still hadn't closed.
A fierce gust of wind blasted straight into his open mouth.
"Gah!"
He flailed, covering his face with both arms as the pressure nearly knocked him off his feet.
In that moment
Seraphina felt it.
That unmistakable exhilaration known only to true swordsmen.
The joy of crossing blades.
The fierce clarity born within battle.
The intoxicating rhythm of life and death dancing at the edge of steel.
A rare opponent.
A worthy exchange.
Yet even Seraphina knew the truth.
In a pure contest of kenjutsu
She was being suppressed.
Kōshirō's movements were too refined.
Too efficient.
Too flawless.
Her swordsmanship, though brilliant, still lacked the polish forged through decades of structured discipline.
But battle was never decided by technique alone.
Seraphina's Observation Haki read subtle shifts in intent.
Her defensive Busoshoku Haki reinforced her guard like invisible armor.
Together
They tilted the greater flow of combat.
CLANG!
A violent surge of strength erupted between them.
Kōshirō slid backward, sandals carving deep lines into the fractured earth.
Seraphina did not hesitate.
She leapt vertically, Winter Solstice flashing downward in a merciless arc.
Steel met steel mid-air.
Clang! Clang! Clang!
A storm of strikes unfolded above the ground, too fast for ordinary eyes to follow.
Kōshirō intercepted each slash with immaculate precision, counterattacking with controlled, razor-sharp cuts.
Seraphina abandoned rigid defense.
Against a swordsman of this caliber
Hesitation was defeat.
SCREECH!
Another brutal collision.
Seraphina was driven back to the ground, boots sliding across torn soil.
She steadied herself instantly.
Moments later
Kōshirō landed opposite her.
Calm.
Unruffled.
"Commander Seraphina," Kōshirō said, adjusting his glasses,
"you are remarkably strong."
His gaze sharpened.
"Who was your master?"
This style
He had never encountered anything like it.
Unorthodox.
Yet undeniably sophisticated.
Every movement appeared natural, almost casual…
Yet concealed razor-edged rigor.
Had the user's fundamentals been more mature
It would have been terrifying.
Seraphina gave a faint, almost sheepish smile.
"I have no master."
A pause.
"I simply trained on my own."
Silence.
Kōshirō's composure cracked for the briefest instant.
His mind rebelled.
Impossible.
Such precision without formal tutelage?
He studied her youthful face again.
No deception.
Only sincerity.
"…Extraordinary…"
Seraphina tilted her head slightly.
"I'm ashamed to admit…"
A faint sigh.
"After such an intense exchange, I neglected to ask the Dojo Master's name."
Kōshirō blinked.
Then smiled gently.
"Shimotsuki Kōshirō."
With measured calm, he sheathed Wado Ichimonji.
The duel was over.
Seraphina's brows knit faintly.
"…You're stopping?"
Kōshirō's voice was serene.
"There would be no decisive outcome today."
His gaze drifted toward the children watching.
"The future belongs to the next generation."
"Let us end this here."
Seraphina studied him for a moment.
Then nodded.
"…Very well."
A slight smile.
"I'll return tomorrow."
As Kōshirō walked back toward the dojo, his expression turned grave.
"A Marine commander of such monstrous talent…"
He murmured quietly.
"…I wonder what the world is becoming."
It was now noon.
The tension of the spar still lingered in the air like static before a storm.
Zoro's fists clenched.
Watching that battle
Feeling that pressure
Had ignited something within him.
"I'm fighting again!"
He pointed at Kuina.
The dojo courtyard quickly filled with students from Isshin Dojo.
But today's audience was unusual.
Commander Seraphina sat quietly at the side.
Her Marine coat draped across the wooden floor.
Silver hair glinting softly in the sunlight.
Observing.
The duel began.
Wooden swords clashed.
Rapid.
Fierce.
Decisive.
"Point!"
"Match!"
"Winner - Kuina!"
"Two thousand victories, zero defeats!"
The bout ended.
Kuina exhaled softly.
Zoro lay sprawled on the ground, teeth gritted.
"Damn it…!"
"You're still weak, Zoro."
Kuina's voice was sharp.
"How can you be this useless?"
"You're a boy, aren't you?"
A ripple of protest rose from nearby students.
"Zoro's not weak!"
"He's the strongest among us!"
"He's beaten adults!"
Kuina's eyes flashed.
"So what?"
"He still lost to me."
"Even using two swords."
"A weakling is a weakling!"
With that, she turned and walked away.
"Losers should stay quiet."
"The louder you cry, the uglier it sounds."
Silence fell.
But Seraphina's gaze followed Kuina.
There was something wrong.
Kuina walked like a victor.
Yet her shoulders carried invisible weight.
Why resentment…
Instead of pride?
Meanwhile
Zoro rose slowly.
"I'm going to wash my face."
His tone was forced indifference.
At the well
"Damn it!"
"Why can't I beat Kuina?!"
"Why?!"
Zoro slammed his fists against the stone rim.
"A loss is a loss."
Seraphina's voice drifted calmly behind him.
"Train harder."
Zoro spun.
Commander Seraphina leaned casually against a pillar.
"I will become the world's greatest swordsman!"
His eyes burned with defiance.
Seraphina smirked faintly.
Amused.
She untied Winter Solstice and tossed it toward him.
Zoro barely caught it.
The blade's weight surprised him.
"Care to test that ambition?"
"…Okay."
Without warning
Zoro drew.
The katana felt heavy yet alive in his grip.
He swung with all his strength.
Seraphina parried effortlessly.
"Too slow."
She yawned slightly.
"Did you skip lunch?"
Zoro's face reddened with fury.
He attacked again.
And again.
Every technique he had learned.
Every ounce of strength.
"Yes…"
Seraphina murmured.
"Faster."
Rage sharpened Zoro's movements.
He slashed with everything he had.
For a fleeting instant
Winter Solstice released a faint, icy arc.
Uncontrolled.
Wild.
But real.
Seraphina's eyes gleamed.
"…So the seed is already there."
She swung her blade lightly.
"Awakening of Insects - Storm Surge."
The air split.
Clouds stirred overhead.
A pressure wave roared past Zoro.
The slash deliberately missed.
Zoro stood frozen.
"…Monstrous…"
Seraphina retrieved her sword.
Her earlier frustration had vanished.
"If the master won't finish the duel…"
She muttered softly.
"I'll entertain the disciple."
As she turned
Zoro's voice stopped her.
"How far away are you…"
"…from becoming the world's greatest swordsman?"
Seraphina paused.
A rare question.
A difficult one.
"…Far."
Her voice was quiet.
"Very far."
From the shadows
Kuina leaned against the wall.
Her body trembled.
Eyes wide.
Heart pounding.
Too strong.
Far too strong.
And for the first time
Fear crept into the heart of a girl who had never known defeat.
