Inside the wooden dome, Hashirama Senju felt the defensive shield cracking under the relentless assault. His face grim, he poured more and more chakra into the barrier, desperately trying to keep it from shattering. It wasn't until he was channeling his power at full strength that he could barely keep pace with the damage being inflicted.
"Monkey, what in the world did you do?" Hashirama demanded, his voice strained as he maintained the jutsu. "Who is this powerful person?" Although he was furious with Hiruzen, he knew now was not the time for lectures. He could also feel that, in his reanimated state, he was no match for the enemy outside.
Hearing this, a flicker of shame crossed the faces of Hiruzen and Danzo before they quickly hardened their expressions. "The man outside is Uchiha Kagami," Hiruzen said decisively.
"He massacred the entire Uchiha clan! We were trying to arrest him when he attacked us!"
Even now, Hiruzen refused to speak the truth.
"What?" Hashirama and his brother, Tobirama Senju, stared in shock.
"He wouldn't even spare his own people? What a monster," Hashirama said, his face dark with anger. He believed Hiruzen's words and was filled with a righteous fury at Kagami's supposed actions. He couldn't imagine the sorrow Uchiha Madara would feel, knowing his clan had been wiped out by one of their own.
Tobirama, however, looked deeply at Hiruzen and Danzo, a thoughtful, suspicious expression on his face. He was shocked by the news, but the look on Hiruzen and Danzo's faces as they told the story made him doubt their words. They were lying. Tobirama was certain of it, but he chose not to expose them. In his mind, the Uchiha were a clan of evil. Their extermination, as far as he was concerned, was a good thing.
He had no idea that his own Senju clan had been wiped out long before the Uchiha.
Outside, Kagami watched indifferently as the wooden shield blocked his attack. He wasn't surprised. This was the God of Shinobi, after all, the man who had once brought the entire ninja world to heel. Even in his weakened, reanimated state, it was to be expected that he could withstand this initial assault. In fact, it would have been more surprising if he couldn't.
However, Kagami hadn't been using his full strength. The slashes that hammered against the shield were only a thousandth of his true power. It was the unique property of his Domain Expansion, the ability to unleash an infinite number of attacks, that created the illusion of such overwhelming pressure. If he were to increase the power of his slashes even slightly, Hashirama's defense would crumble.
Kagami guessed that Hashirama was already using nearly all of his reanimated power just to maintain the shield. Otherwise, with his personality, he would have already launched a counterattack with his Deep Forest Emergence. At this point, Hashirama had, at most, half of his original strength. It was impressive that he could hold on for this long.
Kagami now wielded ten times the power of Sukuna in his prime. At full strength, he could reduce ten Hidden Leaf Villages to ash in an instant. Even among super kages his power ranked near the top. With his instantaneous Spatial Cleave, he was a threat to anyone. He had already activated his Domain. A mere reanimated Hashirama stood no chance.
To save time, Kagami increased the power of his slashes to two percent. The wooden shield instantly shattered into splinters.
Immediately after, before anyone could even react, Hiruzen and Danzo were shredded into pieces by countless invisible blows. The situation had changed so quickly that Danzo didn't even have time to activate his Izanagi. With the death of their summoner, Hashirama and Tobirama's reanimated bodies began to turn to dust and dissipate.
In his final moments, Hashirama stared at Kagami with fury and roared, "Uchiha Kagami, you are evil incarnate! Why would you do such a cruel thing to your own people?"
Hearing this, Kagami looked at the dissipating First Hokage with disdain and sneered, "Idiot. You should find out the truth before you start barking at me." He was a vanquished foe, not even worth the effort of an explanation.
His words sent Hashirama back to the Pure Land with a heart full of reluctance and doubt, followed by the thoughtful, silent Tobirama.
Watching them disappear, a thought sparked in Kagami's mind. He lowered his domain. He had suspected that the prying eyes from before belonged to the Sage of Six Paths. Now, seeing Hashirama and Tobirama return to the Pure Land, he couldn't help but think that the Sage himself resided there.
In the original story, the Sage of Six Paths, though long dead, could return to the world of the living from the Pure Land at will. It was a mysterious, unique ability. Based on this, Kagami guessed that the Pure Land itself might have been created by the Sage. After all, no matter how powerful a person was, once they died, they couldn't return on their own. Yet the Sage of Six Paths frequently popped back and forth, granting power-ups to Naruto and Sasuke.
Even if the Sage was a "good guy" in the original story, he had shown killing intent toward Kagami. That was enough to put him on Kagami's list. But until he was strong enough to face the Sage, he would have to keep a low profile and continue to grow his power. The Sage was an immortal who had lived for thousands of years. Even with the terrifying power of his Spatial Cleave, Kagami wasn't absolutely certain he could win. Besides, Spatial Cleave was a physical attack. Whether it could even harm a soul-state being like the Sage was an open question.
He had finally gotten a second chance at life with this system. He wasn't about to throw it away on a reckless impulse.
Suppressing these thoughts, Kagami looked toward the center of the Uchiha district. When he had expanded his domain, he had sensed Sasuke's presence in that direction. Wary of the Sage, who for some reason had yet to act against him, he had consciously spared Sasuke. Though the Uchiha territory was now a field of ruins, Sasuke was unharmed. The boy had likely fainted from terror at the sheer destructive power he had witnessed.
Just as Kagami was wondering what to do with Sasuke, Uchiha Rinne began to stir, her eyes fluttering open.
