Hidden Emperor Of The Naruto World

It has been six months that Minato has arrived in this world, and 5 months since the first visit to the Uzumaki-Senju compound. A lot has happened during that time.

4 months ago, Mito Uzumaki died and passed the Kyuubi over to Kushina. Of course, it was a secret to only a selected few, but knowing the whole story already, Minato knows the true cause of Mito's death. During the whole month before her death, Minato often went to speak with her, and they hit off well.

Her death was hidden from the world. Speaking of that, her whole life she has been hidden in the shadows. People in the future all talk about the legendary kunoichi Tsunade Senju, not knowing that Mito was by far the most powerful woman of her time. Without her, Hashirama could have very well lost the battle against Madara, after all the Kyuubi has infinite chakra, and it could have killed a weakened Hashirama.

Mito's death caused some ripples. First Kushina was plagued with insecurities, and the Hokage forbade her to spread the world of her condition to her friends. But in the end, knowing the cause of it Minato made her crack and reveal it to him, and when she saw that he didn't care about it, she was so relieved that she cried. They decide to not tell others about it for now because it could be dangerous for them to know it, and who knew if Tsume will spread it by accident, with a blabbermouth like her it could very well happen.

Then, Kushina moved out of the Senju-Uzumaki compound, not willing to intrude anymore on the last members of the Senju clan. Tsunade and Nawaki don't consider themselves Uzumaki, and even if they were friendly, Kushina knew that they have no real familial bonds between them.

She was ready to live in a less than favorable environment, knowing that Konoha people dislike her, but Minato foresaw it and bought the whole complex where he resides. In just one month, his manga racked him a huge amount of money, people buy it left and right, having never seen such an interesting book. Speaking of it, he forgot that the purpose of his visit one month before was to show it to them, and when they learned that he didn't share it with them, they were mad and pout for one week long. They would have loved to pummel him, acting by the 'Anime Woman Love Pummeling Syndrom' (AWLPS), but Minato, not willing to submit knocked them down when they act on it, so they learned to restrain it when with him. Even the ever gentle Mikoto possess it, so Minato was sure that there was something wrong with all anime women.

Kushina, of course, moved in the room near Minato's, but she made a fuss when he said it was free for her. So he just added the rent money and some more to her allowance that the Hokage deposit each month, after all, money exists to be spent, he will not be stingy with his friends. And their small group have now a ritual of eating new delicacies of Konoha daily. When they refused to mooch off him in the beginning, he showed them his account and they shut up and ate, he has enough money to live his life in luxury civilian's way.

Apart from that, he found another canon character in the anime, that he didn't recognize at all in the beginning: Mebuki Haruno, Sakura's mother. She looks nothing like in the anime, she is far cuter than her old counterpart, and not as annoying as Sakura. Kushina has become friends with her, and she sometimes joins them, but she can't be considered a part of their small group at all, more an acquaintance than anything. And even if he found her cute, Minato was not interested in her. She has no real personality proper to her like his three girl friends, acting more like a sheep in the herd of useless fangirls.

Thanks to that discovery, he found that even if he has Minato's memories, during the absorption some bit of it went missing, probably absorbed by the strange black hole in his mind, so to recuperate them he will have to enter it, a thing that he is not willing to do for the time being. And who knows if they still exist inside of it.

After that, he decided to find more about the powers that came from him, aka not the one he acquired by taking Minato's body: the 'Hyper Intuition', 'Mental energy Regeneration by the strong soul', and the blood that came with him in this world.

For the first, 'Hyper intuition', he found that it didn't work only for battles. It can even help him localize concealed places, it's like that he discovered the entrance of the ANBU headquarters, another thing that disappeared when he absorbed Minato's memories. Not only that, it can even help him discern truth from lies and a lot of useful things like that. It acts like a detector: detector of danger, detector of weak points, detector of treasure, detector of lies...

For the mental and physical regeneration, he confirmed that they were real, and it helped him train a lot more. For the physical regeneration, it's mainly his stamina. His wounds healed a bit faster but it doesn't work like the Namekian's regeneration (Picollo of DBZ that can restore body parts), contrary to his mind that is thoroughly healed. He suspects that it's because only a drop of blood came with him, and it's insufficient to have multiple functions.

He doesn't even need to sleep anymore, but he still does it anyway. He is not like those wuxia protagonist that want to strengthen themselves 24h/24. He prefers giving 200% of himself during training and taking the rest of the day to do more relaxing things, with a good part of his relaxation time spent with Kushina, Tsume, and Mikoto doing all sorts of things (Not +18 mind you, he has no libido yet). Well, a clone of him does it the whole day at the academy already, and him after it. They usually gather after the academy for some small spars between them.

Speaking of them, they all had become pretty close-knit, passing their whole time together. There is not a day when they don't hang out with each other.

Concerning the blood that came with him and merged with this body, giving him a high stamina regeneration rate, he confirmed that it has the ability to devour other bloodlines. He called it devouring affinity. He spared sometimes with Kushina, Mikoto and Tsume, and sampled some of their blood without them noticing, after all, everybody has their secrets, he will not reveal this one to anybody. But for now, he still didn't discover if it had any other abilities.

Flashback.

"Thanks again, Nono-san" At the Konoha hospital, Minato, Tsume, Kushina, and Mikoto thanked the nurse Nono, which tends to them each time they finished a pretty rough sparring time where some small blood is shed.

Yakushi Nono was a young woman in her twenties with shoulder-length light brown hair and emerald green eyes. She wore the standard Konoha Hospital nurse uniform, which includes a plain white dress and a hat as well. She also wore circular glasses.

"Don't worry about it, you can come to me anytime" She declared with a gentle motherly smile, giving off an odd vibe because of her young age.

'This crafty Danzo, he can't approach me publicly because of the Hokage, so he found a way to approach me via Nono, a Root failure because of her inability to lose her emotions. But it allows her to blend completely in Konoha especially because of that. I wonder when will she take over the orphanage as the head matron, it's not before years I think, and if she even takes over it. Maybe because of me she will not die this time around, being kept to monitor me instead of being sent to Iwa for intelligence and ultimately being killed by Kabuto. Nevermind, her fate doesn't really concern me, even if she has a gentle soul, in the end, she is more or less the slave of Danzo, it's far too dangerous to try something on her for the time being so let's forget about it. I have to focus first on growing stronger, if something goes wrong I can't even defend myself against her for the time being.'

Exiting the hospital, Minato bade goodbye to the girls and returned home. Away from the prying eyes, he entered his bedroom and took out three vials of blood nearly full, placing them on a small table near his bed.

'It has taken me months to collect the right amount of their blood that my Hyper Intuition ability detected is needed without being suspicious or seen by those that stalk me. Will I really be able to absorb their bloodline. Well, there is no other way to find out than to try'

Sitting crossed legged before the table, he began to even his breath and slow it down, to locate the 'source' of his ability. Ever so slowly, his perception, following his blood network, came to the center of his heart, where the black drop of blood that came with him through the black hole was sitting powerfully in the middle, refining the already existing blood in the body, aka Minato's, into blood possessing the characteristics of the two. To change all Minato's body blood into the new one with only this small drop took months, but finally, the process was about to be finished. He was thankful that the blood that circulates his body is still red, it would have been a bother to have black blood and become closely analyzed.

Yes, he discovered that thanks to his soul, not only he gained an amazing perception dubbed at Hyper Intuition, he can perceive everything inside of his body, from the organs to the tiny cells. And his perception alerted him that inside this small drop of blood hide the same frightening power than the black hole inside his mind, so he did not dare to inspect it closely for the time being.

Boom

Suddenly, inside his heart, the black drop of blood trembled then stabilized, signifying the end of the blood refining. It was finished, his whole body blood is now a mix of Minato's and Byron, with Byron being the dominant and the other absorbed. But the drop of blood didn't disappear, still sitting there quietly. Seeing that, Minato knew that it was not normal, and that his intuition was right. This thing works like a black hole, and maybe if he give it some blood with special ability, it will absorb those abilities.

Tugging at it, with some effort, a small red drop of blood came out of it. But in no time at all, it was reabsorbed.

'It must be the source of Minato's bloodline, well, I doubt that anyone has a 'source' so to speak but my body is different than others. Now that all of this is finished, I can finally test to see if I can absorb others bloodlines'

Uncorking the vial of blood containing Kushina's, a pure Uzumaki with a noble bloodline, he gulped it down.

Coming near it, the blood began to tremble like it was afraid of it. The frightfulness of the black blood could be seen from this if even an entity without a will can tremble in front of it.

Not minding the shivering blood, the black drop of blood absorbed all of it. Seconds later, a thin strand of Kushina blood came out of it and merge with the blood inside of his heart.

The new blood that pumped out of his heart gained a new ŀuster, seemingly having changed a bit even if it was not too noticeable.

Seeing that, he knew that it will take some time before all his blood acquired the qualities of Kushina's. Maybe if he had absorbed more of it, it would have been faster? Maybe not, it could even have an adverse effect to suddenly increase the volume of the total blood in his body.

It took exactly one week for the transformation to be completed, and another two for Tsume and Kushina's blood.

In the beginning, it was a bit hard to adapt to Tsume's blood because of the amplified smells coming through his more developed nose. Thankfully, all of it didn't come in one go but gradually during a whole week, allowing him to adapt to it and discover more smells that were always overshadowed habitually.

So, after that, he finished with 5 sources, his, Minato's, Kushina's, Mikoto's and Tsume's, all mixed into one, or more precisely absorbed by Byron's body blood that survived the tempering of the black hole. After experimentations, he discovered that:

From Minato's blood, he received wind and lightning affinity.

From Kushina's blood, he received water affinity and a boost of his vitality, that helped him heal his wounds a bit faster, and the increase in proficiency of Fuuinjutsu was welcomed. He deduced that the fact that if such a small quantity of blood gave him better regeneration power than the super resilient black blood, it's because compared to the black blood that lives as a separate entity, Kushina's blood merged with his, and so changed his DNA, adding the special abilities to it.

He concluded that if he wants to acquire all the abilities of the black hole inside his mind and the black blood, he has to merge them with his mind and body respectively. Unfortunately, it will not be anytime soon, he doubts that they will comply and not resist. If that was the case, they would have already merged with his body and mind long ago. At least, the black drop of blood gives him bloodline abilities that he absorbed and the black hole in his mind memories of soul he absorbed.

From Tsume's DNA, he received earth affinity and an increase in his sense of smell, prompting him to train his other senses, discovering that they were far more useful than just for daily life.

From Mikoto's DNA, he received fire affinity and the Sharingan. It was foolish of him to have a fixation on Fugaku's blood, after all, Mikoto's talent doesn't lose to him, and it's far easier to acquire it. And thankfully, when all those different bloodlines merged, the black blood is the one prominent with the other absorbed by it, so there is no change in his eyes when he activates the Sharingan, they only flash a bit, which people could misinterpret as Minato pushing chakra into his eyes to see farther and clearer.

It was pretty easy for him to activate it, he just had to remember then anguish that he had when his mother died, the only emotion that his frozen heart has never let go. He would have like to activate it another way, but unfortunately, he doesn't know enough about the chemical reactions taking place in his brain when in anguish to reproduce them. But he will be sure to find them later for the Mangekyo Sharingan, there is absolutely no way that he will kill someone he loves for power, it would be completely against what he dreams of.

He found that the Sharingan was a pretty useful tool. The eye of insight, allows one to see chakra, enhance perception and memories. For the first, it allows him to see what sort of reaction the chakra has inside the opponent's body, allowing him to predict the Jutsu or anything chakra related that he will use.

The second is a good mix with his Hyper intuition, predicting and sensing the danger at the same time could allow him to plan. It's true that directly after dodging, his Hyper intuition will indicate him where to attack, but it's far better to formulate a possible course of action before the action.

The last was useless to him, having such a strong soul and control over his mind allow him to memorize anything easily. But if he has children, this ability will be passed down and useful to them, he doubts that they will inherit his strong soul, it's not a thing that is passed from father to child, a soul is outside of the control of the cycle of reproduction.

The 'Eye of Hypnotism' of the Sharingan is truly useful too. It allows one to cast a genjutsu just by thinking about it. He was pulling his hair out thinking of how creating a genjutsu that alters the sense of space and time and emotions, but now he just has to visualize it and have enough chakra to execute it.

Thanks to smalls vial of blood and his ability, he now has the 5 basic affinities, an enhanced perception of Fuuinjutsu, an enhanced sense of smell and the Sharingan. He would have loved to have the Byakuugan, unfortunately, it will not be easy to have access to the blood of a talented Hyuuga. He could probably take the DNA of a low ranked branch member, but he did not know if absorbing a low-quality one will have any adverse effect. Kushina, Tsume, and Mikoto were more or less royalty of their clans, so their blood was pure and strong, so he absorbed it without hesitation. Who knows if he could eject one DNA from his body. For now, he can't so he won't take the risk of absorbing another Hyuuga blood than Hiashi and Hizashi.
