Seijuro would clench his sword, the blade glinting slightly in the light.
His Karma marking spread alongside his body. He had found a way to fuse it with his Hundred Seal, as it was much simpler than having to activate both abilities separately.
He then entered his Perfect Sage Mode... TLDR, snake, slug, toad.
He could maintain this state of power for roughly 30-ish minutes or so before his body gave out. Sure, he was more Otsutsuki than anything, and he was close to 20—nah, he was 20, fully formed and all—but while his Sage Mode was perfect, as in, it couldn't be improved much further...
His body needed some getting used to.
Ishiki didn't even waste a second. He wanted to get rid of the annoying pest first.
In a millisecond, the man vanished from their sight, appearing in front of Aizen.
Using the Sukunahikona, all of the shrunken chakra rods that he had around would just spawn on Aizen's body.
The man merely smiled.
Aizen would poof away, as Seijuro aimed his blade at the man's neck. Ishiki extended his shrunken rods once more, this time to save his own life, making them block the blade aimed to cut his head off.
Seijuro would jump away, his senses screaming at him.
As he Shunpo'd away, he would watch as—where he stood just a nanosecond ago—several rods appeared out of thin air.
He landed a couple of feet away, next to Aizen.
"He can shrink and expand things," Seijuro would say, more to himself than his counterpart.
"Hm... took you longer than me to realize that. I suppose that means I have the superior intellect," Aizen would say in a rather cold voice.
"Hm... you, however, do possess the Rinnegan. Your visual prowess gave you quite an easy time figuring it out. TLDR, don't glaze yourself too much."
"While yes, I do admit that... your Sage Mode more than makes up for that... mister Perfect Sage."
"Hmph."
Seijuro took his sword, and Aizen smiled as he watched Swift Release being activated in Seijuro's body. He was using Swift and Steam Release to buff his stats even further. A weird goo would begin leaving his body, as bubbles could be seen all around the battlefield.
Oh... the Six-Tail's ability, how neat.
Seijuro moved first.
His chakra flared as the serpentine technique activated, tendrils of energy slithering into the earth like vipers. In an instant, the battlefield responded—dozens of stone spikes erupted from the ground in synchronized bursts, each one aimed precisely at Ishiki's vitals.
The Otsutsuki's expression didn't shift.
"Do you believe this is enough to fool me?" he said coldly, his voice untouched by panic.
He rose into the sky, calmly ascending above the rising spears of earth—
Only for a shadow to appear above him.
Aizen.
His Rinnegan shimmered under the light, glinting like a predator's eye. A calm, devious smirk played across his lips.
Before Ishiki could fully react—
CRACK!
Aizen's foot slammed into his side. Ishiki managed to raise his arm just in time to block, but the sheer force still sent a shockwave rippling outward. Aizen didn't let up. The moment his foot landed, he chained it into a brutal barrage of follow-up strikes, forcing Ishiki onto the defensive mid-air.
Left jab—right elbow—low spin kick—
Ishiki blocked, twisted, and countered—but nothing connected cleanly.
Then Aizen threw a straight punch.
Ishiki reacted instantly—raising his guard, confident he'd caught it.
He was wrong.
WHAM!
The blow landed clean on his face, snapping his head sideways.
Blood sprayed from his nose mid-flight.
Eyes wide, Ishiki reeled back.
What—?
He had the range right. He should've blocked that.
But as the pain blossomed, realization dawned.
He didn't misread the length—
He misread reality.
"A Genjutsu...?"
He muttered, "Kai!" and forced chakra through his system.
Reality shattered like broken glass.
The battlefield returned to its true state—but it was too late.
A massive Rasenshuriken surged toward him, spinning at full velocity.
Ishiki instinctively raised his palm to absorb it—
But the moment his skin made contact—
BZZZT!
Lightning detonated through his nervous system, natural and raw, untainted by chakra. His body spasmed uncontrollably as volts danced along his arms and spine.
"A... decoy...?" he hissed through clenched teeth.
While his body convulsed, Aizen was already upon him again, fists blurring with speed and precision.
THWACK! THUD! BAM!
Each strike found its mark.
Every movement calculated.
Every feint layered under illusion.
Aizen didn't just fight—he deconstructed Ishiki in real time.
He would fake a right hook—only for Ishiki to realize the arm was a clone's.
He'd duck under a counter, slip behind, and pull Ishiki forward with Almighty Pull, drawing him straight into a brutal uppercut.
But Ishiki, desperate, activated his shrinking ability—compressing his entire body into a subatomic size.
Aizen's punch carved through empty air.
Then—
Behind him.
Ishiki reappeared, blade drawn, aiming straight for Aizen's neck—
Only for another shadow to flicker into existence behind him.
"Got you."
Seijuro.
His Rasengan hummed with unstable chakra, and he slammed it into Ishiki's back with brutal precision.
BOOOOM!
Ishiki rocketed down like a meteor, crashing into the earth with such force it sent debris hundreds of feet into the air. He bounced once—twice—then lay motionless, blood pouring from his mouth, his armor fractured.
Suddenly, the realm felt off.
"DAMN YOU FILTHY MORTALS!"
Aizen and Seijuro were confused—like, what did they even do?
As they wondered that, Ishiki's chakra roared like no other. His Karma marking seemed to vanish as his power skyrocketed to new heights.
Odd. He didn't seem like the kind of guy to get mad so easily.
Was two mortals seemingly not taking him seriously pissing him off?
Well, to be fair, they were taking him hella seriously. For fuck's sake, Aizen's eyes never left him, and Seijuro's senses were always on him. They were just good at hiding that fact—making shit look like an easy diff when in reality, shit was hard.
Anyway, Seijuro grabbed his sword and watched as the god... puked blood. Purple veins could be seen all around his body.
Hm... that wasn't normal.
"Oh... seems like the poison's kicking in," Aizen would say calmly, watching as the god's chakra pathways were utterly destroyed by his little poison.
"A poison?" Seijuro would question.
"Hm, yes. After studying your DNA, I made a small little dose. It's harmless to humans, really... but..."
Ishiki dropped to his knees, puking blood, his right eye losing vision.
Fuck... dammit it all.
As he was suffering, Aizen used Wood Style, holding him in place. His right eye spun a bit—don't question it.
"...How... could... I ever lose to your kind?" Ishiki muttered, blood leaking from his lips.
"I refuse to die like this."
Aizen, meanwhile, looked down on Ishiki like he was some kind of god...
No... no... he refused.
CRACK
Reality shattered once more, and Ishiki's eyes widened as Seijuro's blade was mere milliseconds from his neck.
Instantly, he shrank himself, making the blade miss by a hair.
He appeared in the sky a few seconds later—hovering, glaring down at Seijuro and Aizen. His eyes were blazing with fury.
A genjutsu.
A goddamn genjutsu.
No... a multi-layered one.
Those cursed bubbles—Seijuro's absurd floating spheres—they weren't just for decoration. They acted as conduits, amplifying the illusion's reach and potency.
With a scowl, Ishiki's golden eye flared as he summoned five pitch-black cubes, scattering them through the air like obsidian anchors.
Their purpose? To sever all sensory interference—especially that fox's detection.
Kurama's sense had been a problem. One of Seijuro's sage energies... it had to be responsible. That damn human had combined natural energy in such a way that even the environment responded to his illusions.
So... limit the environment.
As Ishiki set the cubes in motion, a storm of 300 missiles tore through the sky toward him.
He scoffed. Child's play.
With a casual raise of his hand, he activated Daikokuten, intending to shrink the entire volley to dust.
...Nothing happened.
His brow twitched. Still, he moved—dodging the wave of steel and death.
Too late.
BZZZT—BOOM!
Seijuro appeared behind him, locking him in a full Nelson.
No matter. He could just shrink himself.
And so, he did.
He vanished—
Seijuro reappeared a moment later, now standing calmly at a distance, watching.
And then—
KABOOM
A thunderous blast rocked the sky.
The explosion was enormous—sickeningly violent, heat rippling like hellfire as it tore through clouds.
Seijuro observed it with mild interest, his expression unreadable.
As the smoke cleared...
Ishiki was still there—but barely.
He floated, half-crumbled, limbs blown off, his body scorched and twitching.
"Damn genjutsu..." he spat, blood leaking from his mouth. Hatred filled his lone eye.
How had it gone so wrong?
Well... when Ishiki shrunk the 300 missiles, he did technically shrink them. But under the influence of Seijuro's genjutsu—powered further by Aizen's reality-bending illusion technique—his mind didn't recognize that.
He believed the missiles were still the same.
And when Seijuro placed a seal on him—something like a negative charge...
Well, let's just say those 300 tiny missiles, now the size of senbon needles and carrying the same explosive power, were attracted to him like magnets.
All at once.
Each with enough force to pierce the Third Raikage's ultimate defense.
So yeah...
The bastard got cooked.
Blood dripped from his mouth. His ribs were shattered. His regeneration struggled to keep up.
But still—he didn't fall.
He refused to fall.
With sheer willpower, Ishiki lunged at Seijuro, eyes full of murderous rage.
If he had to die... he'd take one of them with him.
He gathered the last of his chakra. Maybe he'd detonate his own core, end it all in one suicidal blaze—
Seijuro, unfazed, drew his blade and swung, aiming to slice his head clean off—
But in a desperate gambit, Ishiki reached past him—hand outstretched—and slammed a Karma seal onto Aizen.
A smug smile twisted his broken face. "I'll never die," he rasped. "I'll come back... through you."
He vanished.
His soul raced into Aizen's body, seeking refuge, rebirth, control—
.....
His soul met the same fate Urashiki soul met.
A/N Ishiki is strong, I admit, he outstats the both of them immensely, however, they are his worst ever match up ever.
Everything in that fight was a genjutsu, the breathing, the actions, everything, don't know if yall notice it, but even the byakugan couldn't see through that shit, I bet most of yall fell for that poison line.
Tldr, he was a brawler, having to fight 2 long range illusionist fighter who he couldn't one shot, and mind you, his fight with Aizen has drained him and he is suffering from the poison of the ten tails.
