Book One: The Rise of the Blue-Haired Devil.

      The two giants were ready to lash out at each other. The warrior and the creature from ancient legends and myths were about to start fighting, but they both turned towards a strange sound. It was like the squeaky sound of a mosquito to these huge monsters, but it alerted them both. Their gazes darted towards a small village in the distance, the barrier above which began to flash with a light blue glow.       - Invasion. - Madara growled with anger. He really wanted to continue the fight with this kid who was as strong as he was, but he needed to protect the village he had built with so much hard work. Too much effort and money had been put into this place by the head of the Uchiha clan, the most important of which was his own time. Yes, Madara didn't like to waste time. I figured it out pretty quickly.       - A draw? - I clarified, seeing the look in my former rival's eyes.       - Rrrr... - The shinobi god growled like a wild beast, about to reply in the obvious negative, but a decent-sized explosion near the village made him reconsider. - Good. - The Uchiha added with some resentment. He didn't like to settle for a draw, it was like defeat to him, which he hadn't seen in his life for a long time. The giant samurai disappeared in a moment. I watched it spellbound, fully aware that my opponent was so easily and casually using such great power when I myself was very limited in my abilities. I had some feeling of self-loathing, but I quickly suppressed that silly emotion, turning into a human. It was, faintly speaking, painful... not even that, it hurt like hell. Every cell in my body needed to rest, and my heart was beating at a triple rate, but I steadied myself and began to move behind Madara, who was hurrying towards the village, or rather the site of the huge explosion. I had a bad feeling about this. An unpleasant chill ran down my spine, indicative of the crisis that was setting in. I didn't know who had attacked us, but my instincts and analyses told me that it all made no sense. Whoever the attacker was, their goal was not to wipe out an entire village. It would take too large a force of ninjas to be visible to the naked eye, and even if they weren't, it would be almost impossible for them to get across the border without fighting. They would simply not be missed by the ninja patrols that were constantly on duty near the border. And there was another reason why it would be difficult to get a huge army through to Konoha undetected. The Fire Country was separated by small countries from other countries. The unoccupied territories had a decent amount of scouts from different countries, who were very good at masquerading as mercenaries. Shutting them all up at once was a task beyond normal. Someone would have blabbed for sure. Information is a very valuable resource, although strength is obviously more important in this world, but information must also be possessed, otherwise the story could end badly. All this said that this was a diversion, well planned. The enemy had good sources of information in Konoha, from which he knew that the fight between the two strongest ninja from Konoha and Kiri would be held today. But what is the purpose of this diversion? It's difficult... I don't understand.       Two minutes later, we arrived at the battle site. A small squad of ninjas were fighting against Izuna and Tobirama, who were fighting back easily enough. Somewhere in the distance, the hokage's chakra was just fading, indicating that this was where the main battle was taking place. Madara and I rushed into the battle at once. We didn't know which village our enemies were from. Luckily for me, they didn't turn out to be very strong. Their strength level was between that of a chunin and a weak jounin, and I was able to fight them even without chakra or any body enhancement. I was one hundred per cent sure that the albino and the younger Uchiha could have handled the two of them, but the Shinobi God and I needed answers to our questions.       - What's going on here, Izuna? - Madara demanded in a cold manner when the last enemy was finished.       - Well, we were attacked. - my friend answered him in a voice so innocent it made me shudder.       - Izuna! Tell me something I don't know. - The shinobi god shouted angrily, starting to boil with anger.       - Don't yell. You're annoying enough. This is a delegation from the Waterfall Village. They took the six-tailed man and then immediately attacked us. - Tobirama spoke, wincing at Madara's loud voice. He really didn't like the fact that someone couldn't keep their cool when they needed to.       The head of the Red-Eyed Clan was about to say something, but suddenly, a ball of thread of a completely black colour flew out of the bushes nearby. This ball of thread flew about ten metres away, breaking a couple of trees before it stopped. To my surprise, the ball of thread looked quite human. When the strange shinobi got to his feet, I could definitely see him. The unknown had, like all members of the human race, two legs and two arms. He was quite tall, with a swarthy skin tone and dark brown hair. His peculiarity was his eyes, distinguished by their unique colour. They had a red sclera and green iris without any sign of pupil, which looked very strange. The body of the unknown had quite prominent muscles. But aside from all of the above, the sight of this shinobi was simply frightening. There were many black threads stretching from his mouth. It was as if these threads had a consciousness of their own, being constantly in motion. There were many stitches running through his body. This man looked like he had gone through a great deal of torture or he had been resurrected. Hovering behind him were three strange creatures that only remotely resembled humans. Their bodies were completely made of black threads, and instead of faces, they had strange masks.       - You're alive, aren't you? - said a familiar voice. A second later, Hashirama appeared in the clearing, slightly bruised from the battle, but his gaze was still focused. Tobirama was about to ask something, but he suddenly turned around. Everyone followed suit, for the strongest ninja could not sense the approaching danger. It was a very strange feeling. Usually intuition would warn of such a thing, besides my sensory skills did not sense the presence of the unknown who suddenly appeared behind Izuna's back. The younger Uchiha also sensed the appearance of the enemy, but he simply didn't have time to do anything. A kunai pierced his chest near his heart.       - IZUNA! - Madara shouted, shocked by the sight. In a split second, he appeared next to the unknown enemy, stripping the attacker of his head with a blow of his hand. The shinobi god then fell to his knees in front of his brother, who began to choke on his own blood. I was about to approach them, but Hashimara stopped me by extending his arm in front of me, blocking the path to the Uchiha.       - You're no help here. - The first hokage said, frowning. - You'd better catch up with the guy who's trying to escape. He might know something about what's going on. - The elder Senju added, pointing in the direction I could clearly sense the ninja who had landed beside us a few seconds ago. I had to agree with him. There was no time to mourn my friend. What needed to be understood now was why Izuna had been killed. In fact, I had only participated in the defence of Konoha at all for the reason that my long-awaited fight had been interrupted, but now everything had changed. My friend was killed and I have to get to the truth. Hell, I don't know how the unknown man was so skilfully hiding his presence so close to us, but I was sure the fleeing ninja was partially aware of what was going on. I would still have time to dissect the body of the assassin, but another source of information was now trying to get away from me, travelling at a decent speed, but I wasn't that easy either. My body was under the enhancement of natural chakra, causing me to move much faster than normal jounin.       After two minutes, I had reduced the distance between us from a kilometre to twenty metres. The forest was quite dense, so I didn't immediately come into line of sight with my opponent. When I did, I released five ice pins infused with the spiritual chakra component without a second thought. I wasn't allowed to kill the unknown person, so I tried to stop his futile attempts to escape. A single black monster woven from threads separated from the enemy. The creature took the attack, but before my jutsu hit the monster, the latter managed to release a stream of flames in my direction. I completely immobilised the enemy's puppet, although it was hard to call it a thread monster. It was too self-moving. I dispelled the opponent's technique with a small swing of my blade, adding my chakra to it. The raging stream of fire, which was a true natural disaster, was cut like a rag falling on a sharp knife. The fire stream dispersed in different directions, sensing an invisible barrier. This trick can only work if the ninjutsu user's chakra is less dense than that of the blade user. I caught up to my opponent quickly enough, intending to stab him in the back, but the unknown thread master turned around to face me, delivering a spinning kick with his foot. The power of the kick was amazing. He was not inferior to me, but I was more agile and agile than his counterpart, so I grabbed his leg as he flew up, using his inertia against him, sending him flying into the distance towards the nearest tree, which broke on first contact. The unknown man flew a dozen metres before he managed to completely suppress the power of my throw. I landed not far from him, beginning to assess my opponent with a glance. My enemy's chakra volumes were not inferior to mine, but I knew we were both not in the best shape right now. I had fought Madara before and he had fought Hashirama, so the fight should have been an even match.
