The masked man announced the start of the Fourth Shinobi World War right there in the middle of the Five Kage Summit.
For a brief instant, the room felt like it had been punched hollow. Every Kage's expression shifted - some tightening with anger, others darkening with wary calculation. Even the guards behind them, already on edge, seemed to draw a sharper breath. A declaration like that wasn't simply a threat. It was a line drawn across the shinobi world.
Onoki's lips curled into a cold, contemptuous smile. "Masked man," he said, voice like grit against stone, "you can stand here and shout all you want - but you don't seriously believe the Akatsuki can still contend with the Five Great Nations… let alone the entire shinobi world, do you?!"
The Yondaime Raikage snorted, electricity almost seeming to crackle in the set of his shoulders. "Exactly. In that war back then, even your leader died at the Mizukage's hands. And now you're talking about starting the Fourth Shinobi World War?!"
The masked man threw his head back and laughed, loud and unbothered, as if their outrage was nothing more than a child's tantrum.
"Are you talking about Pain?" he asked, amusement dripping from every word. "Yes, he was the one who helped establish Akatsuki… but he was only ever a piece on my board."
His laughter faded into something colder, sharper. "Now that he's dead, it may not even be a bad thing."
He took a step forward, and the temperature in the chamber seemed to drop - not from chakra, but from the certainty in his tone.
"I'll tell you this much: you'd better mobilize every last ounce of strength you have and prepare to fight. Otherwise, when the wave crashes down, there won't be a second chance."
A pause.
Then his voice rose, forceful and absolute.
"You have no idea how powerful we are now!!!"
The other Kage bristled, ready to fire back, but Chiba lifted a hand - simple, controlled, and final. The room obeyed him almost unconsciously, as if even their anger recognized the weight behind that gesture.
Chiba's gaze remained calm, but there was a faint edge beneath it - like ice under still water.
"Uchiha Madara has returned," he said evenly, "and you've likely created a large number of White Zetsu soldiers as well."
He continued before the masked man could react, his words falling one after another with disquieting precision.
"On top of that, Yakushi Kabuto has spent these years expanding his Edo Tensei ("Impure World Reincarnation") force into an army far larger than before. With those pieces in place… yes, you do have the qualifications to declare war on the entire shinobi world."
The masked man froze.
Even behind the mask, the shift was unmistakable - tension snapping tight, breath catching, chakra stirring in abrupt disbelief.
"Y-you…" he stammered, then forced the words out. "How do you know all of that?!"
Chiba had spoken his hidden cards aloud as casually as if reading a report. It wasn't the first time, and that was what made it worse. Each time Chiba peeled away his secrets, it felt less like intelligence and more like inevitability - like standing in front of someone who could see through walls, through skin, straight into the core of his plans.
Chiba smiled faintly. "I told you already," he said, tone almost conversational.
"I know everything."
Then his voice steadied into something more decisive - less discussion, more verdict.
"Masked man, this war was going to happen sooner or later. And it's time we settled accounts."
His eyes sharpened, cold and direct. "Go back and tell Uchiha Madara - Chiba will be waiting for him on the battlefield."
Something trembled in the masked man's chest, a jolt of irritation mixed with a deeper, reluctant unease.
"Hmph… Chiba," he said, forcing a sneer into his voice. "So you're still that confident."
He leaned forward slightly, as if pressing the question like a knife. "Even the name Uchiha Madara doesn't frighten you in the slightest?!"
Chiba's reply came without hesitation.
"Uchiha Madara - so what?"
His tone was steady, almost dismissive. "He's just a man who should've stayed dead."
Chiba's gaze swept the room - not at the Kage, but at the invisible horizon beyond them, where war was already taking shape.
"This era. This shinobi world. It's not something he gets to rule anymore."
The masked man's voice sharpened into a bitter laugh. "And what - are you saying you're the ruler now?! That you're the one who decides this era's fate?!"
Chiba only smiled, neither confirming nor denying. The silence itself was an answer - one that didn't need arrogance, because it carried certainty.
The masked man's expression twisted beneath the mask.
"Don't be so conceited, Chiba," he spat. "Even if I'm not your match… the real Uchiha Madara is still out there!"
His voice rose, fierce, almost desperate - like he needed the idea to be true.
"His power is beyond what you can imagine!!!"
Chiba's eyes didn't waver.
"Then I'll see him on the battlefield," he said simply, and there was a quiet anticipation buried in the words, the way a swordsman might welcome a blade worthy of testing his own.
He tilted his head slightly, gaze turning colder.
"As for you…"
A pause - sharp as the edge of a kunai.
"You're no longer worthy to be called my opponent."
Chiba raised his palm.
The air changed instantly.
A terrifying surge of extreme cold erupted outward - not merely a wave of ice, but something that felt like the world's breath being stolen. Frost exploded across the space itself, racing through the air faster than sight. Even the light seemed to dull, as if the room had been dragged into a deeper, harsher winter.
In the next instant -
Space froze.
Not the floor. Not the walls.
The very void around the masked man locked solid, turning the air into an invisible prison. His body halted mid-motion, suspended as though pinned inside a crystal coffin. He couldn't step, couldn't twist, couldn't even flinch.
Forget counterattacking.
He couldn't defend.
He couldn't flee.
Chiba let out a low, disdainful chuckle. "A Shadow Clone ("Shadow Clone"), huh?"
His tone carried open contempt. "So you've become even more cowardly than before."
Then -
Bang!!!!!
Chiba closed his hand into a fist.
The frozen space collapsed.
The restrained figure shattered instantly, crushed into powder and dust as if ground down by an unseen godlike pressure. The remains dispersed - and then, just as quickly, became a plume of white smoke.
A clone.
In the original history, that man had come in person to proclaim war at the summit. Now, after losing to Chiba again and again, he no longer had the courage to stand here himself. All he could do was send a substitute to speak in his place.
The Kage and their guards stared at the spot where the masked man had been obliterated. Even if it was only a clone, it had carried terrifying power - Kamui ("Divine Might") from the Mangekyō Sharingan, and the strength of a single Rinnegan. That level of force was enough to stand above almost every shinobi alive.
And yet it had been erased in a heartbeat.
Only because it had faced Chiba.
Onoki and the Yondaime Raikage exchanged a look. In each other's eyes, they saw the same thing - fear, and something close to reverence. Because they could feel it: Chiba's strength now was even more unfathomable than it had been over two years ago.
Onoki exhaled, heavy and resigned. "Mizukage… it seems Madara truly has returned."
His voice lowered, as if naming that fact tasted bitter. "Then this Fourth Shinobi World War… it's already an arrow on the string. We can't avoid it."
Chiba nodded once. "That's right."
His tone remained controlled, but his words carried the weight of a command decision.
"This war is inevitable. But it's different from before. It's no longer conflict between the Five Great Nations."
His gaze hardened.
"This time, it's war against Uchiha Madara - and against the entire Akatsuki."
The room grew still, listening.
"So we cannot afford old grudges," Chiba continued. "No hesitation, no suspicion, no cracks between us. We have to unite - top to bottom, nation to nation - so we can face them as one."
His voice dipped, colder than the air had any right to be.
"Because if we fail to do that… Madara and Akatsuki will exploit the gaps."
"And when they do," he said, "what gets destroyed won't be one village."
"It'll be the entire shinobi world."
Onoki's expression tightened, and he nodded. "The Mizukage is right. This is the greatest threat the shinobi world has ever faced - an unprecedented terror."
His eyes narrowed, as if seeing the ghost of the past rising over the present. "Back then, Madara's ambitions were restrained by Shodai Hokage Senju Hashirama. He couldn't unify the world by force."
Onoki's voice turned grave. "But now that he's returned… his power may be even more frightening than before."
He paused, then said the truth no one wanted to admit.
"We'll only have a chance if we go all out."
The Yondaime Raikage nodded, jaw clenched. "To think someone like Madara - something out of legend - would appear again… it's hard to believe."
Gaara spoke next, calm as wind over sand. "Sunagakure will fight alongside the other great nations. There will be no additional conflicts."
As the Godaime Kazekage, that was more than a statement - it was a choice made publicly, unmistakably.
After all, the hatred between Sunagakure and Kirigakure was known across the shinobi world. For Gaara to say this meant Sunagakure was abandoning old enmity, choosing unity over vengeance.
And it was, frankly, inevitable.
Compared to Kirigakure's current strength, Sunagakure was no longer a rival that could dream of retaliation. Ants did not wage war against elephants - not unless they wanted extinction.
Gaara's decision was the most rational path.
Chiba glanced at him and gave a small approving smile. "Good."
Then Tsunade turned toward Chiba, her gaze firm, voice carrying the authority of someone who understood exactly what leadership cost.
"If this is a war for the entire shinobi world," she said, "then we must unify completely."
She drew a breath - then spoke the words that sealed the era.
"I propose that the Mizukage, Chiba, serve as Supreme Commander of the Five Great Nations."
"We will form the Allied Shinobi Forces and face Uchiha Madara and Akatsuki together."
Her eyes swept the room like a blade.
"Who agrees - "
" - and who objects?!"
Everyone understood. Tsunade's proposal aligned perfectly with what Chiba himself intended.
But when those words rang out - who agrees, and who objects - no one dared to challenge it.
Because in the shinobi world, the final truth was always the same.
Power was everything.
Chiba smiled, calm and unhurried, as if he were simply accepting a duty that had already chosen him.
"If that's what everyone believes," he said, "then I won't refuse."
He lifted his gaze, and the air in the chamber seemed to tighten - not with fear, but with resolve.
"I declare it here."
"The Fourth Shinobi World War officially begins!!!"
"And starting today - "
"The Allied Shinobi Forces of the Five Great Nations will be formed!"
