Konoha Security Department

Three days seem to have passed in the blink of an eye. Tonight, the Konoha and stars are sparse in Konoha, but probably no one would have imagined that on such a beautiful moonlit night, a momentous event that would shake the entire Shinobi World is quietly taking place.

The cold wind howled in the dead of night. The two ninjas stationed at the Uchiha Clan Konoha Military Police Force were drowsy, their eyes filled with sleep. The long night seemed to have made them a little tired. However, their movements, though seemingly casual, seemed to maintain a certain vigilance, their eyes inadvertently scanning their surroundings.

"Whoosh..." At that moment, figures suddenly appeared around the Konoha Military Police Force. They were shrouded in a cold aura, and their eyes looked at the Konoha Military Police Force, which was under the control of the Uchiha Clan, with indifference and cruelty, as if they had already sentenced the ninjas within to death.

'So they've finally arrived...' The Uchiha Clan ninjas stationed on either side of the Konoha Military Police Force exchanged glances, their eyes filled with understanding, yet they still managed a perfunctory shout, 'You are... Root ninjas?! This is the Konoha Security Department! Get away immediately! Otherwise, you will be treated as missing-nin!'

"Truly dedicated to their duty..." Danzo's figure slowly emerged from the shadows of the crowd. Without even glancing at the two Uchiha Clan ninjas, his gaze fell upon the enormous emblem on the Konoha Military Police Force building. "The Uchiha Clan crest shouldn't be here... From today onward, this crest will be completely gone..."

With a slight wave of his hand, several Root ninjas surrounded the two Uchiha Clan ninjas. The Uchiha Clan ninja, seemingly still unaware of the situation, shouted, "Shimura Danzō! You've led Root ninjas to surround the Uchiha Clan's Konoha Military Police Force! Are you betraying the village?"

No one paid him any attention, but the Root ninja in front of him suddenly pulled out Kunai, which already made their answer clear.

"The Root Clique has rebelled!"

"Shimura Danzō rebels!"

After shouting twice, Inabi Uchiha and Tekka Uchiha smiled as they looked at the Root ninjas who had surrounded them. Their eyes instantly turned bloodshot, and their Three-Tomoe Sharingan Sharingan glared fiercely at the Root ninjas. Unbeknownst to everyone, behind them, a camera faithfully recorded everything...

(The Shinobi World has movies, computers, and so on; its technology is quite advanced...)

"How interesting... Root has rebelled..." The voice seemed to come from afar, but it suddenly exploded in everyone's minds. In an instant, all the Root ninjas felt their brains become a little dizzy, and they involuntarily looked up at the high-rise building of the Konoha Military Police Force, where a man's figure was standing quietly.

The moonlight shone through Kato Osamu's back, revealing only a slight outline. The night breeze gently ruffled his hair, and a faint smile appeared on his lips.

"Sometimes, time is very long, but sometimes, time is very short..." As he spoke, Kato Osamu's figure suddenly disappeared, and when he reappeared, he was already very close to Shimura Danzō.

"We meet again... Shimura Danzō ..." Kato Osamu's eyes met Danzo's quietly. Even though there was still a slight smile on his face, a hint of coldness suddenly appeared in his eyes.

"Protect our leader!" The Root ninjas seemed to have recovered from some kind of shock. The unknown enemy had appeared, and the figure had suddenly disappeared. Although they seemed to know that they were no match for him, they still loyally surrounded Kato Osamu, who had suddenly appeared next to Shimura Danzō.

"Enough with the noise!" With a soft snort, Kato Osamu suddenly unleashed a peculiar aura. All the Root ninjas who were about to make a move suddenly felt a blackout before their eyes and collapsed to the ground like wheat being harvested, completely lifeless...

"It's you... Mi!" As if just recovering from shock, Shimura Danzō's eyes widened suddenly. He finally remembered that the person in front of him was a former member of Root, a boy codenamed 'Mi'.

But now, at this crucial moment, it has appeared before him, and with such methods...

How is that possible?!

"Ah, it seems like it's been many years since I've heard that title... Danzo, you remind me of some unpleasant experiences..." Inabi Uchiha and Tekka had already left, and the Konoha Military Police Force was now completely empty. Around the Konoha Military Police Force, besides the corpses of Root scattered on the ground, only Danzo and Kato Osamu remained, standing silently facing each other...

"You actually dared to come back! And even colluded with the Uchiha Clan..." In an instant, he understood everything. Looking at Kato Osamu, Danzo felt a surge of rage. In his eyes, Kato Osamu was a traitor to Root, a traitor to Konoha, and the Uchiha Clan were traitors to the village. And now, these two traitors had actually colluded together...

On the night of the massacre, Danzo led the Root ninjas to besiege the Konoha Military Police Force, while Yamakaze led the Root ninjas to the Uchiha Clan to monitor Itachi Uchiha's actions, retrieve the Sharingan, and verify his identity.

The initial intelligence indicated that the Uchiha Clan Konoha Military Police Force had a number of tough members, so Danzo brought only the elite of Root. He never expected them to be lost so easily. Even Danzo, upon seeing the Root ninjas lying dead on the ground, was both horrified and furious...

"Hmph, it seems you've returned this time to take my life..."

"Not only that..." Seeing the enraged Shimura Danzō, Kato Osamu didn't continue his attack, but chuckled lightly, "The Uchiha Clan, which you've always considered evil, will succeed in their coup. You will become a traitor to Konoha, and our beloved Third Hiruzen Sarutobi, will die at the hands of his most beloved disciple, Orochimaru..."

"Shimura Danzō... you'll never become Hokage in your lifetime..."

"Boom!" As if to confirm Kato Osamu's words, a sudden explosion erupted from the Hokage Building in the distance, and the billowing smoke was clearly visible even from the Konoha Military Police Force, far from the center...

"Damn it! You traitors! You think you can do it?" Shimura Danzō intently at Kato Osamu, but a gaze couldn't kill...

"Uchiha Clan... should have been eliminated long ago! Hiruzen! You were wrong this time!" Danzo glanced at the direction of the Danzo Hokage Building and retreated rapidly, knowing that he had to fight to the death this time. Clusters of wind blades came from all directions towards Kato Osamu.

"Wind Release: Vacuum Bullet!" Despite his advanced age and frailty, Danzo had immersed himself in the training of wind attribute for many years. The ordinary vacuum bullet in his hand was incredibly powerful and had even changed shape, with countless bullet-like air balls heading towards Kato Osamu.

"The power of Wind Release is not bad, but it's far from enough..." Kato Osamu's figure flickered, easily dodging all the air currents by simply shifting his feet left and right. The ground of the Konoha Security Department was already riddled with holes. Even Kato Osamu had to admit that Danzo's Wind Release skills were indeed very high...

"Wind Release: Vacuum Serial Waves!" Seeing that his attack had missed, Danzo a deep breath, and a continuous air wave, like an endless stream of water, rushed towards Kato Osamu. The air wave swept across the jungle and the ground, and countless trees collapsed instantly, while the ground cracked and a huge cloud of dust rose up.

"Wind Release: Shuriken!" At the same time, several Shuriken, accompanied by the fluctuations of Wind Release, suddenly emerged from the smoke and dust. The power of Wind Release propelled the Shuriken to spin rapidly, and a sharp edge enveloped the Shuriken, forming a huge circular blade like a disc, cutting anything in its path in two.

"Yin Yang - Soul Blade Annihilation!" Before anyone knew it, a jet-black longsword had appeared in Kato Osamu's hand. He flipped his body to Wind Release: Wind Shuriken, and the longsword in his hand was already heading towards another Wind Release: Wind Shuriken that was heading straight for his face.

Like a hot knife through butter, the Wind Release: Wind Shuriken, which had been flying at high speed, seemed to lose its momentum the moment it encountered the black longsword. All the Wind Release Chakra attached to it dissipated into the air, and the Shuriken fell to the ground with a tinkling sound.

The crisp sound seemed to silence the entire battlefield. Danzo's eyes were filled with disbelief; he knew all too well the power of his Ninjutsu, yet it had been so easily neutralized...

Danzo narrowed his eyes slightly, suddenly recalling his past encounter with Kato Osamu —that unique power that, even now, still baffled him, was capable of neutralizing Ninjutsu...

"Boom..." The Wind Release: Wind Shuriken that Kato Osamu had dodged headed straight for the Konoha Security Department building, instantly slicing off a portion of the entire building. As if freed from the constraints of friction, the severed part began to slowly slide down along the cut marks...

"These are truly unheard-of methods... It seems you, traitor, have acquired quite a few skills over the years... But no matter what, you were once nothing more than a dog at my feet. Now, has the dog learned to bite its master?"

"Wei, you should thank me for my kindness in surviving until now..."

"Shimura Danzō, it seems you haven't realized your place yet..." A flash of anger appeared in Kato Osamu's eyes, and he tightened his grip on the long sword in his hand. Those unbearable memories resurfaced before his eyes.

"Also, my name is Kato Osamu!"

A faint glint flashed in the black blade in Kato Osamu's hand. His angry attack seemed to transcend space, appearing abruptly in front of Danzo. The blade pierced straight into Danzo's body, and blood gushed out, blooming onto Kato Osamu's face, adding a touch of ruthlessness to his appearance.

"So fast... even Ninjutsu is ineffective..." Danzo a grim face, glancing at Kato Osamu, whose body, which had been pierced by Kato Osamu, suddenly vanished...

"I didn't expect to have to use you so soon..." Suddenly appearing behind Kato Osamu, Shimura Danzō's arm, previously wrapped in bandages, was revealed. Countless Sharingan were embedded in his arm, making it look terrifying...

"This is..." Sensing the fluctuations that appeared behind him after Danzo's disappearance, Kato Osamu turned around. Looking at the densely packed Sharingan on Danzo's arm, Kato Osamu's gaze narrowed slightly. Back in Root, he and Orochimaru had conducted research on Wood Release and the Sharingan. It seemed that Danzo had succeeded...

However, even Kato Osamu felt a little apprehensive about having so many Sharingan fused on his arm.

"I never imagined that a single wrong decision back then would allow you, a traitor, to grow to such a level..." Danzo seemed to have gained confidence as he slowly and gently stroked the Sharingan on his arm, before revealing a ferocious expression on his face.

"Today, we will completely destroy you, you traitor, right here and now!"

Holding Kunai in one hand, he attacked Kato Osamu almost without dodging or avoiding. Kato Osamu flashed forward, brandishing his long sword. When he reappeared, he was already behind Danzo. The long sword pierced Danzo's body again, but as before, Danzo's body disappeared.

"Wind Release: Vacuum Sphere!" The sudden surge of Ninjutsu behind him made Kato Osamu frown slightly. With a slight movement of his hand, countless Soulfire Insect suddenly scattered. Danzo's attack was nothing to Kato Osamu now. If it weren't for this method of suddenly disappearing and reappearing, he would have been killed by Kato Osamu with a single strike.

Having dodged Danzo's attack once again, Kato Osamu used the Soulfire Insect to sense Danzo's every move from every angle...

"It seems to be the effect of the Sharingan..." Suddenly, Kato Osamu realized that the two Sharingan on Danzo's arm had somehow shut down...

"I see..." The moment the black blade pierced Danzo's body, Kato Osamu could sense that it had definitely pierced Danzo's body, and was not some kind of Genjutsu. But in the next moment, Danzo seemed to have suffered no harm whatsoever. With Danzo's abilities, he could never use such a technique indefinitely. If the cost were minimal, the Hokage of Konoha would have been Danzo long ago...

"Then, that makes things easier..." Understanding that the cost was limited, Kato Osamu chuckled softly, his hands subtly forming Hand Seals. "I'll just kill you a few more times..."
