Within the vast sea, there existed a sealed space known as Danku (sealing barrier)—
a closed barrier with no entrance and no exit.
Inside the barrier, layers upon layers of lightning surged like overlapping mountain ranges.
It was a place where life and death were decided at will,
a domain where existence itself could be erased.
Where thunder roared in the tens of thousands—
there lay a Lightning Hell.
Where thunder roared in the millions—
there lay a Greater Lightning Hell.
Where thunder roared endlessly, without cessation—
there lay the Avīci Great Lightning Hell, from which there was no return.
For the four Kirigakure shinobi who had chosen to fight Hagoromo head-on,
this barrier was, without question, a Lightning Hell.
For anyone, choosing to fight Hagoromo inside a sealed, confined space was never a wise decision.
The smaller the space, the more restricted the enemy's movement became—
and the more absolute Hagoromo's advantage grew.
In such an environment, he could seize superiority with ease—
absolute superiority, overwhelming superiority, superiority beyond measure.
Victory was virtually guaranteed from the outset.
This second confrontation with Yagura was decided the moment Hagoromo completed the barrier.
Inside the sealing formation, his enemies could neither flee nor evade,
neither counter nor prevail.
This battle differed completely from their previous encounter.
There was no elaborate strategy, no tactical layering—
only brutal simplicity.
From beginning to end, Hagoromo used only one technique.
In truth, Hagoromo had not come to Kirigakure to fight.
He had come to end fights.
Combat was not the objective, nor the focus of the mission.
Thus, he needed to finish decisively—and quickly.
He could not afford to be dragged into prolonged combat and miss the appointed time.
And so, from the very start, Hagoromo unleashed his most lethal method:
Level 5 Lightning user – Lightning Release:
Dual-hand rapid fire: 16 rounds per minute.
A simple calculation sufficed.
In his normal state, the effective range of Hagoromo's basic Lightning Release: was 50 meters.
The sealed space was a cube with a side length of 81 meters.
Which meant—
Standing at the center, Hagoromo's attack radius formed a sphere of 50 meters,
completely covering the entire barrier.
Within Danku (sealing barrier), wherever he pointed—
he hit.
There was nowhere to dodge.
For someone capable of sustained, planar rapid fire,
whether the barrier contained four enemies or forty made little difference.
And under continuous high-output discharge, the effective combat space shrank even further.
Hagoromo standing at the center, releasing uninterrupted high-voltage, high-power lightning,
was itself both the ultimate offense and the ultimate defense.
The Mist shinobi could not approach him—at all.
Thus, the four could only remain at the edges of the barrier,
attempting long-range attacks.
Which meant the battle boiled down to this:
Within the Lightning Release:'s kill zone,
the enemy exchanged long-range ninjutsu fire with Hagoromo.
Even imagining it was enough to grasp how tragic this scene was.
Under such conditions, even a shinobi of Yagura's caliber was utterly powerless.
With Hagoromo's extreme firing rate, combined with the enemy's restricted movement,
he could predict their actions with near-perfect accuracy.
The Lightning Release: was unavoidable.
And what could not be avoided—
could not be defended against.
What ninjutsu could possibly stop such an attack?
Water Release: Water Formation Wall?
Earth Release: Earth-Style Wall?
Absolute defenses that these Mist shinobi didn't even possess—
Lightning Release Chakra Mode?
Gentle Fist: Rotation?
Sand Armor?
And even—
Susanoo?
Whether Susanoo could block it was uncertain.
But everything else?
Impossible.
Perhaps if Yagura had already become a fully realized Three-Tails Jinchūriki,
he might have stood a chance—
at the very least, he could have fired a Tailed Beast Bomb to shatter the barrier.
But he had no such opportunity.
And now—
he never would.
From above or from the side, the battle was impossible to see clearly.
The barrier itself was semi-transparent,
and the combination of violent air currents and extreme heat filled the interior with steam.
But the thunder—
the thunder could be heard clearly.
All that could be seen was lightning saturating the entire cube,
thick bolts crawling along the barrier walls like vines growing and withering at the speed of light.
At the center burned a single, unwavering point of brilliance—
like a candle flame within a lantern.
Then there were the scattered orange-gold streaks of light—
countless, inexhaustible—
and, from time to time,
bursts of crimson mist.
Each bloom of blood signified the death of an enemy.
Details were impossible to discern from outside.
But soon enough—
the thunder ceased.
The lightning vanished.
And the barrier dissolved.
From start to finish, it had existed for less than five minutes.
When Danku (sealing barrier) disappeared, only one figure remained.
Hagoromo.
The four enemies—who had believed themselves superior in both number and strength—
were gone.
All that remained upon the sea were expanding clouds of blood.
Even so, Hagoromo could not have maintained full-power rapid fire for the entire duration.
Five minutes at sixteen shots per minute would have meant eighty Lightning Release:s—
utterly impossible.
That would have truly drained him dry.
In a sealed space, attacking constantly moving targets with a single method,
Hagoromo fired fewer than twenty times.
Even so, the expenditure was enormous.
He had already entered power-saving mode,
and would need time to recover.
Yes, the Lightning Release: was a monotonous, linear technique.
But what did that matter?
When it was fast enough,
powerful enough,
precise enough—
what could the enemy possibly do?
This interception attempt, for Yagura and the others,
was nothing more than shackling themselves
and throwing their bodies before a ravenous lightning beast.
A lightning beast with unprecedented aggression.
They simply hadn't realized it beforehand.
From the very start, they were fish on a cutting board.
The barrier did not open because Hagoromo dismissed it.
It collapsed naturally.
Even with suppression in place, the Lightning Release: had riddled it with countless breaches.
When the sea breeze finally dispersed the scalding steam,
Hagoromo's figure was fully revealed.
Aside from chakra exhaustion—
he was virtually uninjured.
The ocean returned to calm.
Hagoromo resumed walking forward,
his steps steady, without hesitation.
Yagura—
a man destined to become the Fourth Mizukage—
now lay dead like any nameless shinobi,
at an unknown time,
in an unknown place.
The only difference was the extremity of his death.
Even at the end, Yagura likely never understood
how Hagoromo's combat style so thoroughly violated the fundamental laws of ninjutsu.
Normally, power and risk were proportional.
The stronger the technique, the greater the danger.
Yet Hagoromo cast S-rank and higher techniques
as casually as eating or drinking.
Even setting aside bodily strain—
what about chakra consumption?
No one would ever answer Yagura's final doubts.
May he read more books in his next life.
Learn more.
And perhaps—
not be born a Kirigakure shinobi again.
