Kakashi and Obito, once close friends who shared life and death, now consumed by deep-seated hatred and irreparable pain, finally met for their last battle.
Bang!
Clang!
Boom!
Kakashi's voice, ragged with heavy breaths, tore through the air. "Obito, why have you become like this?!"
Obito roared, "Why?! Because you stood by and did nothing while Rin died!"
"Kakashi, you killed her with your own hands! You destroyed everything I cherished!"
Rin's name was like a poisoned kunai, piercing into the deepest wound in Kakashi's heart.
Obito seized that fleeting moment of distraction, his right leg delivering a heavy kick to Kakashi's chest.
Kakashi stumbled back a few steps, clutching his chest and panting heavily. "Rin... that was because..."
"Shut up! You're the one who killed Rin!" Obito's roar drowned out everything else.
Another heavy punch landed on Kakashi's face.
The intense pain, however, ignited Kakashi's fighting spirit. He didn't fall. Using the force of his head turning, his body naturally spun around.
A side kick, whistling through the air, swept fiercely towards Obito's waist. Obito hastily blocked it, and a dull thud echoed once more.
"It's time to end this, Obito."
Kakashi steadied himself, and wiped the blood from the corner of his lips, his eyes turning cold and resolute.
He slowly raised his right hand. A piercing, sharp noise suddenly erupted, and dazzling blue lightning frantically condensed in his palm.
"Suits me just fine!"
From Obito's arm, sharp wooden spikes extended.
Without further words, the two figures shot forward, carrying their final obsessions and power.
Towards each other, towards their end, they charged without hesitation.
Thud!
Kakashi's lightning-infused arm fiercely pierced through Obito's chest. However, the deadly wooden spike in Obito's hand, at the very last moment, subtly veered away from Kakashi's vital point.
"Heh. Cough! Cough!"
Obito's body stiffened abruptly, the intense pain making him cough up a mouthful of blood that stained Kakashi's arm.
But a strange curve appeared on his lips as he stared intently at Kakashi. "Useless Kakashi, you'll always be one step behind me. Now I can finally go see Rin, and you..."
"You'll be all alone, forever living in this disgusting world, hahahahaha!"
"You don't even deserve to die by my hand."
The laughter abruptly ceased, and the light in Obito's eyes gradually dimmed.
His body lost all support, slowly tilting forward. Finally, with a thud, he fell heavily onto the cold ground.
Kakashi's arm remained in the piercing position, warm blood flowing down it.
He looked at the familiar yet strange face on the ground, and a profound sense of emptiness and indescribable sorrow instantly engulfed him.
"Obito... you could have killed me... why did you hold back again?"
—
Beneath the ground, Black Zetsu squirmed frantically through the cracks in the soil, roaring silently.
He felt like he was about to have a heart attack.
"Useless! Useless! Useless!"
"It's one thing to be unable to defeat Satoshi, but now he's holding back against Kakashi."
"Who do you think you are? You're the Ninja World's super villain, a Konoha rogue ninja, the murderer who killed your sensei and his wife."
"Now you're acting like a good guy? What were you doing before?! Trash!"
After cursing, Black Zetsu quickly thought of a countermeasure.
Forget it, don't think.
Obito's gone, hurry up and run.
Where there's life, there's hope.
At worst I'll wait another seventy or eighty years, until these people die of old age. Then I'll find a few easy to manipulate young people...
Pfft!
As soon as the thought aross, cold black rods, without warning, pierced through layers of soil and plunged fiercely into Black Zetsu's core.
"Oh no!"
Black Zetsu writhed frantically, trying to break free from the black rods' control.
"Why! Why does he know I'm here?!"
More and more black rods stabbed in, instantly pinning him down, giving him a full-body acupuncture treatment.
Then, a furious roar echoed, and a tremendous force suddenly erupted.
The ground within several meters around him was shattered by this force.
Black Zetsu, who had always been hidden in the darkness, was exposed to the sunlight in such a way.
A figure slowly walked from the edge of the shattered pit, looking down at him.
"You are the Sage of Six Paths's third son, Black Zetsu? You really don't look like him at all. Have you had a paternity test?"
Satoshi squatted down and gently poked Black Zetsu's contorted body with a black rod.
"What nonsense are you talking about? I was never that idiot's son. I am..."
"Hmph! You don't deserve to know my identity."
Unexpectedly, Satoshi lowered his voice and slowly leaned closer to Black Zetsu. "I know that you've actually been taken over by Orochimaru. The current you is no longer Black Zetsu."
Black Zetsu was about to break down. You've got to be kidding me.
If you say I'm Hagoromo's son, at least some people would believe it, since it's all from the same era. It's only one generation down.
But for you to say I was taken over by Orochimaru, that's just too absurd.
How much do you hate Orochimaru, that you pin everything on him?
It's a good thing his corpse isn't here, or he'd revive from anger on the spot.
Just as Black Zetsu was internally roaring, on the verge of a mental breakdown, the long-absent electronic voice echoed in Satoshi's mind again.
[Mission progress updated.]

[Awakened exclusive ocular jutsu: Kamimusubi—Creates a temporary conceptual vacuum or rule-negating domain. Within this domain, one can designate the negation of a concept or rule's effectiveness.]
Hmm?
An unprecedentedly powerful force slowly surged through every part of Satoshi's body. And his eyes, once again, underwent a subtle change.
"Such immense power, hahahahahahahahaha!"
The hedgehog-like Black Zetsu watched with wide eyes as six tomoe slowly appeared within Satoshi's Rinnegan.
This... why can his eyes still evolve?!
He's clearly just an ordinary Uchiha brat, but why can he be this strong?!
And the Chakra on him... Why does it feel so familiar to me?
What exactly is this despicable Uchiha brat?!
Black Zetsu, poked into a hedgehog, fell into unprecedented despair.
An Uchiha with unprecedented strength and intelligence—how could such an overpowered existence appear in the Ninja World?
But even in such dire circumstances, Black Zetsu did not give up hope.
It didn't matter that Obito was gone, and it didn't matter that he was captured now. He still had Kabuto, his subordinate. There was still a chance for everything.
