Time of transition

Some incomprehensible sound, like noise, rustling, sometimes with an increase in volume, there are sharp sounds and rumblings. Sounds of struggle, punches to the body, muffled sounds. How much more time will pass since Naruto fell into an unconscious state, Sasori did not know, but he was sure that he would manage. Shinobi who were sent for support infiltrated the operating room. But who to support now? The red-haired one was fighting them, trying to protect his "partner," cutting their bodies into pieces with chakra threads. There was little space. It was only a fight at medium and close range. A deadly fight. There were about twenty people who came, but they scattered throughout the medical point. Only five managed to get to the temporary "partners." While Sasori was diligently trying to save not only himself but also Naruto, the blond himself had no intention of regaining consciousness, but something did change in him. His back was completely covered with a red cloud, from which two tails emerged with incomprehensible protrusions. At first, Sasori did not understand what was happening, slowing down a bit in the battle, examining him closely, then he was filled with unknown horror when he sat on the operating table and with a bloodthirsty smile tore out the IV and other interfering wires from his veins.A second later, he stood on his feet and looked up. The bloody red pupil met the brown eyes, and at that moment, Sasori slashed the opponent's stomach with a kunai. He fell to the floor dead. -What are you doing?!-Sasori shouted while running to Naruto, to which he merely twisted a bloodthirsty smile and raised his head. -Do they want his body? Do they want blood? Then they will get it.-After these words, Naruto, or rather Kurama in his form, flew at the enemy and with one movement of his hand tore out the opponent's throat. The sounds of the struggle had already attracted other shinobi who were ready to attack when they suddenly saw what had happened to their colleague. The shinobi lay on the floor with a torn throat, blood spreading in a large puddle around, while the blond was bloodthirstily licking his blood from his fingers. Sasori had completely lost his senses. His instinct for self-preservation screamed at him: "Fight!" but curiosity held him back. He really wanted to see how he fought in this terrifying form, but for some reason, he was sure of one thing—Naruto would not touch him. "Precise and strong movements, sharp, like a hummingbird. No unnecessary movements. Correct trajectory of the strike, no flaws," Sasori thought, peering into the movements while Naruto fought. He himself preferred not to get into the fight, as he understood that the fox demon was trying to drink blood, but... for what? Preparation? Then, for what? The red-haired one often asked himself many questions about the persona of his partner. Some boy, who was essentially a vessel for the demon, had come to Akatsuki. He agreed to all the conditions, which, unfortunately, he did not know, and now he was protecting one of the strongest shinobi in the organization. Strange, isn't it? While he was in thought, Naruto had already managed to kill all his enemies. His hands and mouth were covered in someone else's blood, shallow breathing again, and as if an increased body temperature. As if steam was coming from his body, but it was just a haze in the eyes. In a moment, the young man fell to his knees and laughed loudly, as if someone had told him a joke, then he lay down on the floor and closed his eyes. Sasori felt slightly uneasy, as the aura in the room had strangely changed. -Naruto...- he whispered, taking a small step towards him. Naruto turned. The head turned to the comrade and the laughter abruptly stopped. -Are you sure? a loud and menacing voice penetrating to the bones. Self-assured and low. -Fox? he asked, slightly extending his hands forward, showing that there was nothing in them. -In this body, besides the two of us, there is no one else. Naruto turned his head back to its original position and looked at the ceiling.-Don't be afraid of me. -I'm not afraid of you.-Sasori was getting closer. - Where... Naruto? - he said with a slight pause. -He is temporarily absent. - Kurama said with a bloodthirsty smile, then sighed. His consciousness is far from here. -Why did you take over his consciousness? -I needed it. For one important matter. - the fox spoke calmly, while Sasori was starting to suppress a small growing panic. -For this matter, you needed blood... -Yes. Right now Naruto's body is changing along with the systems and mechanisms. His thinking has become different. Moreover, such omegas as he easily break, and to gain support, they need to acquire at least three pillars: strength, resilience, and perseverance. - the fox answered enigmatically. -You can't say that he is weak in spirit? -He is not weak. Far from weak. A fool, but there is enough strength in him. And now I will go. Naruto will wake up in forty minutes. I have put all my strength into his regeneration. - Kurama said, closing his eyes. He no longer answered Sasori's questions, his breathing had stabilized, and his aura had shifted to a calmer one.       Forty minutes later, Naruto indeed woke up, but he remembered nothing. Inside, he was surprised by Sasori's stories, who had been sitting for about 10 minutes telling what had happened to him. All necessary analyses and procedures had been conducted, and the partners decided to head to the shelter.       On the way, Naruto increasingly noticed things he had previously paid no attention to: the rhythmic gurgling of a small waterfall, the chirping of night insects, the silence, the calm streams of wind. Everything seemed new. Naruto did not notice how far they had run in silence, how much was left to the shelter; the main thing was the peace that now reigned around him and within himself. -Sasori, - shouted Zetsu, Pain-sama is waiting for you with Naruto.       The partners were already approaching the shelter when they were met. Naruto, to be honest, was scared, as he did not know when his hour of judgment would come, while Sasori remained quite calm. At least on the outside.       They headed straight to Pain, bypassing a black-and-white spot on the side. A turn to the right, straight, to the left. Naruto had already immersed himself in his thoughts to be ready to answer his questions when suddenly, unnoticed by him, Sasori opened the office door, walking straight to his desk. Pain was sitting behind it, strict, visibly angry, his brows slightly knitted together, and his hands were clasped, resting his chin on them. His forearms were bare. -Did you call?- "Right to 'YOU'? Sasori, you are immortal," - thought Naruto, following the red-haired one. -Yes. Explain why there was an unplanned night walk?-Pain did not get up from his place, did not move. He looked at Sasori with a piercing gaze, as if he was about to kill him, or at least punish him. -I wanted to talk to you after returning to the shelter. - Sasori fell silent and tensed. -You are condemning this boy to death! he said as if he had shouted. Loudly and sternly. Sasori sighed heavily and lowered his head. He did not want to speak in front of Naruto, but now he had nowhere to go. -No. We were at the nearest medical tent. I needed to undergo examinations. -And to involve the shinobi of the nearest country. - added the redhead. -Yes. We stayed there longer than planned, - Sasori added with disappointment. -What kind of examinations? - Pain immediately changed the subject. -I... - Naruto began, trying to either justify himself or really talk about his ailments. - Strange things are happening to me. Sasori suggested these examinations to me, and I agreed to them. For now, I am a combat unit of this organization, which may be needed at any moment. -Sasori, why didn't you tell me about this?- "Did Pain find it surprising?" - the blonde thought. -I wanted to come to you with a complete picture, with analyses and examinations. -What strange things is Naruto talking about? -Memory loss, loss of consciousness, nosebleeds, uncontrollable laughter, redness of the iris, release of the nine-tailed chakra. - At the last one, Pain was indeed surprised. -He can release such power at will?! - he asked, glancing at the blonde. -No. This happens when Naruto is in great danger. His body is covered with an orange-red shell that heals his wounds. At that very moment... - Sasori glanced at Naruto, the fox changes consciousness with him, and then the actions of the nine-tailed fox follow. I spoke with him today when Naruto was unconscious. He does not pose a danger unless that danger threatens his vessel. -I see. - Pain added after a few seconds, Your task will be to learn everything possible about all this. Close observation and training. I will call you when I deem it necessary, and now good night, - said Pain, and Naruto and Sasori left the head of the organization's office. Sasori pondered whether it was possible to gather more information and how best to do it, so he looked very gloomy and even depressed, while Naruto was simply horrified that shortly after his appearance in "Akatsuki," he had already been to the head due to a regime violation.The partners parted at the corridor fork. Naruto quickly threw a couple of words, something like "Good night," and quickly headed to his room, as if hiding from all problems. The thought that he was a TEMPORARY member of the organization bothered him, that from this moment there would be close attention and observation; he felt like a burden, but at the same time, he was obliged to warn Pain about his "little" problems in this way. He felt as if every day could be his last, receiving moral and constant pressure from this thought. The positives were that he could still engage in training, meditation, and dedicate himself to his own modernization.Entering the room, Naruto almost immediately undressed and threw his clothes somewhere aside. He wanted to understand what Kurama had been doing while he was gone and at the same time get important answers to his questions. The only way to contact him in a calm state was meditation, so without thinking, the blonde sat in his usual position and tried to focus.After an hour, Uzumaki finally managed to delve into the depths of his mind. Again walking through the corridors of his consciousness, the young omega stumbled upon the one he had been so purposefully searching for. The fox was still lying in the cage, resting his head on his front paws. The atmosphere was extremely tense. Kurama knew why Naruto had come, but he did not want to answer his questions. He wished that Naruto would figure everything out himself. -You... You!!! - Uzumaki pointed a finger at the huge creature - How dare you...What to do?! You even told Sasori everything! -It's true. I should have left you alone with that boy. You would have been killed, and maybe it would have been easier for me. Less headache. -Ah, you...! he shouted again, pointing his finger.-What did you do when you switched places with my consciousness? -Nothing special. I covered your whole body with my chakra. It was safe, and the wounds you had healed instantly.-Kurama still hadn't lifted his head, and Naruto could only marvel at the new information.-If I had the opportunity to ask for your permission, I would still have received a refusal. -Yes! - Naruto shouted, but a minute later he seemed to change. -What else can you do besides this? ...       The next morning, Naruto woke up literally in a great mood, if only it weren't for the wild pain in his stomach, which started from his stomach and ended at his hip joints. At first, the young shinobi didn't understand what was happening, but then, as soon as he got out of bed, he felt liquid running down his legs. "No! No! It's still too early!" -Naruto thought, trying to gather the natural lubricant with his hands. It was coming off poorly enough to get rid of it completely; it kept reappearing. He decided to go to the bathroom to bring himself to some sense, but that decision was also so difficult to execute that all remaining thoughts faded into the background.Still, Naruto lay on the bed and tried to suppress his moans and desires. The pain made it hard to breathe, coming in waves, then receding again and again. The entire sheet was already covered in lubricant, which embarrassed the virgin omega; it caused him discomfort, from which he involuntarily moaned. Loudly or quietly, he didn't even know.       After a few hours, there was a knock at the door. Naruto was absolutely out of it; he understood that someone had come, but he couldn't even shout permission to enter. Still, the guest slowly and carefully opened the door, and the scent of the omega's heat hit him in the nose. It was like the smell of the sun, just as unobtrusive and pleasant, making him want to breathe it in deeply, closing his eyes so that every cell of his body could soak in that aroma. -Did you lie to me about your last heat? Or are you not tracking it at all? -Sasori asked as he walked into the room. He didn't go further than the threshold, leaning against the door with his shoulder and crossing his arms over his chest. -I didn't know... - Naruto groaned, gripping the blanket in his fists, breathing heavily. - Get out. -Ashamed of your nature or afraid of losing control? - Sasori's provocation worked. The blonde glared at him and slightly grimaced.-I see. I'll inform Pain that your heat has started and ask him to cancel your mission. You're not in a condition to complete it.-Naruto was not against such a decision. Indeed, he felt terrible. His whole body ached, his bones felt broken, his mind was cloudy, and his vision was darkening. Sasori left quietly and silently, leaving the shinobi alone in this wild fever.       For three days, Naruto lay in bed, trying to quell the throbbing desire that was driving his body into incredible exhaustion, forcing him to submit to his natural instincts. Someone brought him replacement sheets and took the old ones away. He never saw this person, as it all happened at night. Sasori didn't disturb him, and the entire organization seemed to have disappeared somewhere, which was quite strange. During this period, temperature was rare; mostly, the discomfort came from the lubricant, pain, and the erection that couldn't be calmed even through a day of masturbation. Naruto was grateful to all the Gods that the heat lasted only three days. If it had been more days.       He would definitely have jumped on someone's member from the organization. The long-awaited day had come when the shinobi emerged from his room for training. His previous mission was canceled, and no new ones were planned yet.       Stepping onto the large training field, Naruto felt a surge of energy. He took shurikens out of his bag and began throwing them at the first tree he saw as a warm-up. -Shadow Clone Technique!-Uzumaki shouted, crossing his index and middle fingers in the shape of a cross. Next to him, from a thick cloud, appeared an exact copy of Naruto, followed by another one. -Well, what this time?- said one of the clones, sitting on the ground. -Shut up, lazybones,- the real Naruto said, furrowing his brows and looking disapprovingly. The other clone approached the original and directed all his chakra to the wind element, while the original focused his chakra on creating a Rasengan. The resulting small sphere Naruto decided to test on the same tree, and it turned out quite well. The tree fell to the ground with a loud crack, rustling its young green leaves, scaring the birds on its top and nearby. Naruto was pleased. He felt a surge of immense power."The fox didn't deceive me," he thought. From that day on, the organization's cloak brought him no discomfort; on the contrary, it gave him even more confidence. -I see you're not wasting time,-came a voice from behind. The blond merely turned his head to the side and saw Itachi out of the corner of his eye. He was, as always, restrained in words and movements, exhibiting the demeanor of a stately male, which was felt quite clearly.-I can help with training. -Yeah, that would be nice.- Naruto grinned ominously and turned his whole body towards the older Uchiha. -I warn you, there will be no games.- Itachi pulled out a kunai from his sleeve, which was fastened to a snap. -I'm not Sasuke to play with me.-At this remark, Itachi smirked and prepared to use genjutsu. Naruto knew the power of the well-known Sharingan, so he tried to look at the opponent's feet.Uchiha realized that he couldn't catch him in genjutsu yet, so he decided to start with simpler attacks: kunai, quick movement. After a couple of quick moves, Naruto felt the chakra point on his hand close. The opponent's movements were invisible, as if he moved like a bird, unnoticed and fast. His body itself was covered with a red-orange coating, like a protective cloth, releasing two tails and small ears. -Interesting,-Itachi said, attacking again. This time his attack came straight on. This is the famous Sage Mode, and the eyes of that very fox? Itachi stepped back a few meters. This time Naruto decided to attack first. The sound of kunai striking kunai echoed throughout the forest, leaving an echo behind, birds scattered all around, and there were mostly crows occupying all the branches of the trees. Sparks flew from the weapons, illuminating the faces of the opponents during close combat, and the strength did not seem to leave them. No matter how many times Itachi attacked Uzumaki, he always knew where he would have to take the hit and always fought back, and in moments of attack, Naruto adjusted the necessary angle or position, and with each strike, it got better. Uchiha still received several wounds from the kunai. One hit his arm, and another was a scratch on his chest. The colors changed sharply; everything around became somehow sharp, black-red-white, the sky flowed so quickly that the eye couldn't track the trajectory of the clouds' movements, then a sharp return of the clouds and the red moon back, while Naruto was pinned to a cross. Opposite him stood Itachi, holding a blade near his stomach. The weapon was already almost cutting into the skin making a cut in the clothes. -You still fell into genjutsu. You are in Tsukuyomi. Perhaps, twenty-two hours will be enough for you. - Uchiha said, slowly wounding Uzumaki. -What are you even talking about? -Twenty-two hours of pain in genjutsu equals one second in the real world. - Itachi finally pierced the opponent's body, causing him to howl in a voice not his own from the pain. Naruto felt not only the burning pain that spread throughout his body but also a surge of an enormous amount of chakra, and the subsequent wounds seemed no longer as painful as the very first one.       After twenty-two hours in genjutsu, Naruto collapsed to the ground. At first, Itachi thought he had overdone it by assigning him such a time, and when he saw signs of life from Uzumaki, he immediately exhaled discreetly, shedding the tension from himself. Yes, perhaps a person would not die from physical wounds, but he could go insane, although Naruto had nothing left to lose. Everything he could do, he had already done, and he was not consumed by guilt for all his deeds. -You are stubborn. - Uchiha said, seeing how Naruto rose to his trembling legs. Blood smeared across his face, flowing from his nose. He successfully wiped it with the sleeve of his cloak and stood in a more stable position. -Weak... - the blonde said, taking a deep breath, bloodthirstily smirking. Uzumaki forcibly made the remnants of his own chakra move to his hands, creating a Rasengan, but not an ordinary one. With the help of the demon inside him, a sufficiently large ball of reddish color was formed, around which streams of wind of the same color swirled. This happened spontaneously, without any specific goals; Kurama merely added chakra so that he could strike the opponent.       Uzumaki moved forward. The blood-red eyes, which surprised Uchiha a little, and the behavior of the young shinobi raised many questions. How did he manage to get up from the ground after Tsukuyomi? How could he gather all the chakra, even though it was clear that he was exhausted? Uchiha had to retreat from the attack until the enhanced technique met its target, namely the stone. It turned to fine dust that was carried away by the wind. -That’s enough for today. I think you understand your mistake. - Itachi said, hiding his kunai. Naruto approached him and stood directly opposite him, silently, without any movements or words, but after a few minutes, he finally began to speak. -I told you, I am not Sasuke. - Itachi was shocked. Why did he remind him of his little brother all day when he had previously tried to avoid this topic altogether? -Don’t underestimate the Uchiha clan. I don’t know how you got up from the ground after Tsukuyomi, but you shouldn’t get cocky. There are no limits to self-improvement. - Itachi deactivated his Sharingan, and instead, black, pitch-like pupils appeared. -Well then, today’s upgrade was successful. - Naruto smiled at him and, bypassing Itachi, headed towards the hideout. His body ached, bringing pleasure. A sense of self-worth, superiority over Uchiha, pride. The aching muscles were stretched so much that he could feel every cell of them; the tendons felt too hot for body temperature, and the lightness in his legs allowed him to jump and run for several hours straight. Naruto decided not to go to the doctor, feeling quite normal.       After the so-called upgrade, the young omega almost stopped eating. As if food was something unnecessary for the body, as if it betrayed heaviness to the whole body, so he decided to eat only once, and that in the evening, before bed, so that his body would not consume itself. -Stop! - a familiar voice sounded from behind, ominously Smirk and Stop, Looking Back at the Periphery. -Itachi, I finished training.-Externally, Naruto also changed after he opened those very ominous huge gates to the fox. He became significantly calmer, angrier, and indifference was his first novelty. And now, standing before a strong opponent and simultaneously a comrade, he felt no fear, felt no all-consuming sadness, felt practically nothing. He was amused by Itachi's behavior, the behavior of everyone living here, the situation, everything. -I wanted to talk about something else.-Itachi stepped closer, assessing Uzumaki. - We better talk in my room. -You live in the same territory as Kisame. - Naruto said, rolling his eyes.-Let's go to my place. I'm alone. Naruto did not listen to Uchiha's response. If he asked for a conversation, then there was something to talk about, and it was a serious topic. He knew that the famous Itachi Uchiha would follow him. -Make yourself at home. But just don't forget that you are a guest, - Uzumaki said, taking off the Akatsuki cloak.-What's the point of the conversation?-Naruto took the jug of water standing on the table and poured a full glass, draining it in two gulps. -How do you feel? - Uchiha was noticeably worried, so he started from afar. He sat on the edge of the bed, mimicking Uzumaki's movement. Taking off his cloak, he leaned on his knees with his elbows, gradually restoring the chakra that was spent on training. -Quite normal, - Uzumaki turned to face his partner and sat on the table. The silence dragged on; something was wrong. - Something else? -Why do you constantly remind me of Sasuke? You know that to me... -You decided to talk about your brother? The genius of the clan has matured? - Uzumaki laughed out loud, interrupting his partner, sitting next to him. -So why? -Before, I cared about everything that happened and is happening with you. I just wanted to tell you what he did for you, what he went through, and now... I don't care. But still, I will inform you: he trained for days on end, did not sleep for weeks to reach the top before all our classmates. At the age of twelve, he was already on par with Kakashi Hatake, learned the Chidori technique, and all for the sake of being strong. Constant use of the Sharingan led to the point where he could visit the hospital several times a month. Once, he almost died from it. He learned to use a blade, completely closed himself off. He tried to talk to the Hokage, to his assistants, and all in vain. Once, he even wanted to leave the village to find you... - Naruto thoughtfully rested his index finger on his chin, then smirked and returned his hands to their previous position. I wanted to help him, to rush into battle with him, but now... I absolutely don't care about him, about your relationship, about your clan. Before, I wanted to help you, but now I don't. Not because I am hurt or angry at the younger one, but because I don't care. -He is not ready to meet me, but thank you for wanting to help him, - Uchiha said, lowering his gaze. -You must understand that he is far from your abilities, and he will not catch up with you. You will die faster than that happens. -I doubt it, - he whispered. -Ah, yes, sorry. Strategist, logician, genius of the clan. That's what they called you, right? Did you calculate everything? Want me to tell you something? You miscalculated. Long ago, nothing has gone according to your plan; everything is worse than you think. - Naruto fell back onto the bed, throwing his hands behind his head. -Only a member of my clan can kill me. - Itachi suddenly got to his feet.       Looking at the serene Naruto. -I was told that you hide your emotions well... Heh, what a disappointment. Don't be so sure. -You know, you've changed a lot since you joined the organization. -Itachi was quite outraged by Uzumaki's words, but he did not show his indignation and slight anger. He turned in place and, taking his cloak, headed for the door, leaving the room. Naruto, meanwhile, continued to lie on the blanket, rejoicing, feeling his certain victory over the older Uchiha. Three days had passed since their conversation. Uzumaki constantly dedicated himself to training, Uchiha quietly observed him along with Sasori, discussing new techniques and the amount of chakra. Akasuna diligently tried to explain some points to Uchiha that he did not know, while Itachi assessed every move of the blonde, every movement, almost every breath, drawing parallels with his brother.       Looking at the serene Naruto. -I was told that you hide your emotions well...

Akasuna diligently tried to explain some points to Uchiha that he did not know, while Itachi assessed every move of the blonde, every movement, almost every breath, drawing parallels with his brother. And indeed, Naruto was somewhat similar to Sasuke in character. Just as detached, with a dark aura, with a thoughtful and heavy gaze, as if deliberately repelling others, even his movements were the same as his brother's. Only externally they were completely different. Everyone around Uzumaki noted that he had changed. He became more like a loner, his speech rough, which repelled his comrades. Over the past week, the blonde had lost weight. Now he resembled a fragile omega, but in reality, it was not so. He had become stronger. New techniques appeared, which he learned himself or listened to Kurama's advice, and those he had, he improved, and now they were several times more powerful. After a day, Uzumaki received a sealed envelope with the mission he had been waiting for. For now, he did not open it, but he knew that Pain would not belittle him, as he was still being watched and reported on his successes.
