Genji's eyes blazed with fury. The battlefield trembled as he unleashed his full power, chakra spiraling violently around him like a divine storm. The bones protruding from his back, glowing faintly with a blue aura, danced with deadly elegance—a manifestation of the hybrid Hyuga-Kaguya bloodline he had mastered through sheer will and pain.
Isshiki Ōtsutsuki stood tall, seemingly unfazed. But Genji saw the tension in his posture, the way his gaze narrowed ever so slightly. The celestial being was not used to this—being cornered.
"You dare defy a god?" Isshiki's voice rang out like thunder, filled with disdain and disbelief.
Genji raised his arm, bones spiraling outward into a javelin of polished ivory. "You're not a god. You're just another monster who's overstayed his welcome."
With a roar, he lunged forward. Their clash shook the air—blinding light against crushing shadow. Palm strikes infused with Gentle Fist met the unrelenting force of black rods. Bones erupted from Genji's arms, slicing through space with the precision of a thousand years of bloodline evolution.
But Isshiki was relentless.
Each attack he absorbed, deflected, or turned into an opportunity to retaliate. He shrank and expanded his black cubes, warping the battlefield to his advantage. The very air around them became toxic with pressure. Craters spread like plague sores beneath their feet.
Blood splattered across Genji's chest. A black rod had pierced his side—but he ignored it. His focus was absolute.
Suddenly, Isshiki's body flickered—vanishing and reappearing behind Genji. His hand extended, palm flat, ready to strike—
—but Genji was faster.
"Dance of the Reaper Fang."
In a burst of chakra and bone, dozens of sharpened spears erupted from Genji's back, spiraling outward in every direction. Isshiki twisted mid-air to avoid the worst, but one spear grazed his face—cutting the cheek of a so-called god.
That moment of pain was all Genji needed.
He struck.
A Gentle Fist-enhanced palm collided with Isshiki's chest, chakra seeping deep inside, disrupting his flow. Isshiki gasped—his vision warping.
"You… bastard…"
"I'm not done yet," Genji growled.
With a final cry, Genji channeled everything into his next move—a suicidal fusion of Gentle Fist and the Kaguya clan's final technique:
"Dance of the Void Blooming Lotus."
His bones exploded outward in a flower-like burst of pure chakra-enhanced destruction. The light swallowed them both.
As the dust cleared, Isshiki's half body was gone fully destroyed by the jutsu and Genji cracks were forming on his body he was about to die.
Isshiki knew that if he lost now he would truly be dead as this Genji would also be dead and nobody would be present to have the kara mark of his.
Isshiki rushed towards Quon intending to place the kara mark on him so that even if he died he would still have a body to comeback with and even stronger as Quon was a Otsutsuki.
Isshiki arrived in a instant as Genji couldn't get up due to the backlash of the justsu.
"You brat you shall be my vessel. Your father I admit he could have killed me but now all is useless with the kara mark on you. You shall br my new vessel. Isshiki began to transfer the kara mark onto Quon.
But,
"Poof!"
It was Quon's Shadow Clone.
Isshiki having wasted the time provided Genji the opportunity to lauch his final attack.
"Shikotsumyaku: Ash Born" This is the final attack Isshiki. With this marks your end. You will never take over the body of my son. You who called himself god died to the hand of this mortal.
In the final seconds of the battle, as the world crumbled and Genji unleashed his ultimate technique.
Both his and Isshiki bodies began to disintegrate. Genji looked at his son "Quon, your father can't stay with you and can't help you grow up. I wanted to see you rise up the ninja world with these eyes. Wanted to teach you all the justsu. But i will watch from the pure land. You will become a great ninja in the future, the strongest infact. So do well my son forgive this father." With that both Isshiki and Genji were nothing more than powder.
Isshiki Ōtsutsuki was gone—destroyed in the wake of Genji's final blow. His physical form disintegrated, leaving no trace. The monster who had threatened the world… had been erased.
The wind howled across the battlefield. Night was falling. Quon lay in the dirt, the world spinning around him. His body screamed in agony. Blood pooled beneath him. The rods were still embedded deep in his flesh, stifling his healing.
He crawled toward the center of the crater.
"Father…" he whispered.
There was nothing left. Only a few crumbling bones, still warm.
His hands trembled. Rage and sorrow warred inside him. His father was gone. The only man who had protected him, trained him, believed in him…
Dead.
Quon slammed his fists into the earth, again and again, until his skin split and bled.
"I should've died…" he sobbed. "Not you…"
The rods pulsed with chakra-suppressing energy. Quon tore at them, screaming in pain, until one finally ripped free. Then another. His vision blurred, but he didn't stop.
When the final rod hit the ground, something inside him shifted.
His chakra roared to life.
The Kaguya blood stirred, angry and alive. His wounds sealed just enough for him to stand. Bone armor crawled along his spine like instinct. He breathed—shaky, but stable.
He turned to the horizon.
"I will make sure that they pay for what they did to you father."
Quon's voice was hollow. Cold. Not broken, but reforged. The boy who had arrived with a glimmer of hope was gone.
In his place stood something new.
A survivor. A weapon. A storm waiting to be unleashed.
As he walked away, he whispered into the wind, "I won't let your death be meaningless. I'll become stronger than even you… Father."
The battlefield fell silent once more.
But in the heavens, a god had fallen.
And a legend was just beginning.
(Perhaps the only thing that could kill Isshiki was the Shikotsumyaku. I believe so as this jutsu eradicates the soul and the body. Since this Isshiki hasn't fully been born he was still quite weak and in the beginningof the battle. He looked down upon Genji and Kaguy's technique. Which lead to his death)
