New sharingan, Nine tails, Ningen

Saber had gone from a little kitten to thick tiger. His saber tooths were especially eye catching. Just looking at them made you afraid. He also has the attitude of an apex predator. Though he was docile around mugen. That didn't lessen his intimidation in any way at all.

Mugen looked at saber from head to toe. "You've gotten more tiger -like" Seeing the blood on his fangs, a headache assaulted mugen. "Should he let him eat humans." He pondered. He decided against it.

" Hey, saber no eating humans okay, don't want you catching any diseases, of course ripping them apart is allowed. " Mugen smiled and petted saber. Saber growled and rubbed his head against Mugen's hand.

"What the fuck!!! That's all you say to him and you say such terrifying words smiling. Are you a demon??!!!!! " the anbu thought to himself.

"Oh and nice progress, it would be great if grew even taller. As big as a mountain." Mugen smiled and continued petting him; thinking of Aoda, katsuyu and the likes of gamabunta.

" OMFG!!!!!!! Do you want the human race to live in fear!!!! " the anbu screamed in his mind.

After a while he finally calmed down his inner thoughts. He gulped, "Well then I should be returning now." He ran clumsily as fast as his legs could carry him , quite un-ninjalike.

Mugen was dressed in a pitch bla ck coat with only his sandals and lower face showing. He kept petting saber thinking about how he got here. It was quite puzzling. "Well it doesn't matter all that much now I suppose."

"Saber with your current size I can't bring you with me. You would be quite eye catching in covert operations, for all out battles it should be fine though. We already have a contract. I'm sorry little one but I'll have to leave you somewhere else and summon you when I can, okay." Hearing him call such a massive tiger little , even though saber was only one size larger than normal tigers, people would roll their eyes.

"Roar" saber lowly roared in disapproval. "I'm sorry but it can't be helped" Mugen sighed.

Saber backed away and his body began to pulsate. It seemed to expand and shrink at the same time. Crr ackle. Some bone like sounds echoed. Saber turned back into a little kitten. It jumped into Mugen's arms.

"Huh!?" Mugen said astonished . It seemed the reverse of the akimichi's technique. How could saber do it. Mugen had no idea. But again standing still pondering would do nothing.

-------------------------

The war was picking up. The other great nations started to move. Mugen had a hand in all the major battles. He wasn't at the lead nor was he a n ordinary footsoldie r(ninja). In every battle he reaped quite a bit of lives. It didn't affect the outcome much all it meant was, the leaf would have more surviving shinobi. He also didn't limit himself to the leaf's battle fields. He went over in the clashes between other enemy nation's as well. Now that was going to edge of death so many times you'd pose count. He had refined control of his ice through his life and death experiences and watching shinobi perform their techniques.

He had taken command of many shinobi from the leaf and news of the Blue eyed Reaper spread. Enemy spies were everywhere so word of his exploits got out. They say no one knew how skilled the blued reaper was but rumour has it he has killed the most shinobi from all nations in the war. He was already placed in every major village's bingo book. Even his own.

He had gotten injured numerous times. As he was still young he healed quickly. Strangely, he didn't catch a glimpse of Tsunade in the medical unit. But when he thought about it, that was to be expected, she had haemophobia. He didn't want his paths to cross in his current body, not just yet anyways.

The war was a good experience for Mugen , he refined all his skills. He purposefully stayed on missions outside and didn't return home. He sent word to his mother now and again but he didn't return. He was quite hard on himself and ensured he fought everday. He never picked a fight though, he'd just stand still and casually, seemingly unintentionally show them his dreaded headband and that would set them off. It was like being pirates. If you weren't in the same crew you were enemies. He needed the experience so he didn't act reserved. He had gotten quite a few infiltration and espionage missions due to his appearance. He had gone to the land of lightning several times along with the other enemy nations.

Why naruto thought the clunky head band looks good was beyond him, then again without it naruto would just look like a average looking guy with cat whiskers: minato was supposedly handsome and while kushina had an annoying personality, she was beautiful, so how did their genes create That. One of this world's great mysteries with the likes of why tobi'singan couldn't be seen at first but was suddenly noticed when he changed voices.

Now in addition to the monikers of yellow flash, red sand etc. There was a new moniker of unconfirmed affiliation. Some say he's from a smaller hidden village others say he is a demon that appears in times of war, great nations suspected the others and all sorts of gossip. The Blue eyed frost reaper. His ice was noticed in his battles. Due to this, kirigakure was the main suspect of many, as there resided the yuki clan but he killed quite a few of them as well.

---------------------------------

6 years later.

In the hokage's office.

Sarutobi was facing outside and with his hands behind him. "Is he still refusing to return?"

An anbu knelt on one foot waiting on him. Knowing the 'he' whom he is referring to he answers. "After we went on that mission together a month ago, I haven't heard from him. He sends back letters to give to his mother at a specified location and the status of his missions now and again but that is all no signs of him returning as of yet. "

Sarutobi sighed, "He has completed hundreds of A and B rank missions, especially during the war where he had several S ranked missions. He is still young and should enjoy his youth. Though he has the mind of an old man like myself. The ones who have worked with him all sing him praises saying he is the greatest captain they could ever wish for. I'd thought he bribed them but that doesn't seem to be the case. What say you kensei? You've worked with him." Hiruzen laughed.

"Ah yes sir, he has a nimble mind and is very wise. We avoided several clashes do to his intelligence. The words he said to us that day still are fresh in my mind.....

Flashback

1 month before.

They had assisted a traitor in killing some of his fellow ninja and successfully sabotaged and enemy nation.

Guki, the man finished betraying them and afterwards started crying. He took out a knife and was about to drive it through his heart. An anbu appeared and stopped him. "Please don't stop me" he begged , even though he was about to commit suicide and his tears drowned his face; his tone was calm and steady.

Mugen was in charge of the mission. He had become a jōnin immediately after the war a year or so ago. He was also an anbu captain. He walked to Guki. He looked into his eyes and asked, "Have you.... Lived?" . Guki, looked as if he was in contemplation his eyes grew resolute. "Yes!"

Mugen recalled his spiteful words, curses and attitude towards his corrupt family. They had inadvertently killed his lover and he hated them. Along the mission he constantly cursed their names. He had fooled both himself and them . He had loved his family, friends, colleagues and fiance. When they died his true feelings sprouted. Rather than their corrupt selves, he cherished the memory of the people they once were. He was middle aged and his entire life consisted of those same people. They were gone and so was his life. He had resigned himself to join those who betrayed him and his fiance.

"If that is what you wish so be it." Mugen said to him, " Do you want me to finish it for you? "

The man looked at him, Mugen had took off his mask.

"No, dying by your hands would be an honour. I don't deserve it. I deserve the same time of death as th em. " he replied.

He again attempted to kill himself, He drives it all the way through his heart.

Mugen turned.

"Captain why do you think he did it." The anb u with a fox mask asked. The same one who was speaking to hiruzen.

"His actions... I doubt he, himself knew the logic behind them. We humans may think we understand ourselves but truly we don't."

"You might think he ended what could have turned into a better life but that's not true. His life consisted of them. Any life after would be an epilogue and not the true story. He might not have died honorably but he did so without regrets."

"So I say to you all in this room. You only live once but once is enough of you do it right. There is no medicine for regret so live your lives like it's the last day of your lives. In our line of work that may very well be the case." Mugen said with a melancholic tone.

" Arrange for his burial. We leave tomorrow. "

"Yes captain!!!!"

Present day.

"I see " Hiruzen said. He truly is a mysterious fellow.

--------------------------------

At the entrance to the village.

A person appeared. He was about 150cm tall. He wore a close fitting long sleeve plain black v-neck t-shirt. He wore black ninja sandals wit h socks. The portion a little below his knee was bandaged down to his socks. He wore a pitch black straight paints. A leaf headband was hanging from the hilt of his katana attached to his waist. He wore a silver chain with six tomoe looking items attached rested on his neck.

His hairstyle looked like grimmjow 's but instead he had white hair. His face was also simil iar to rikuo's, if nurarihyon had married the yukiona that was hitting on him in the second season and they had a child, he would look exactly like this young man now, without the long hair.

Mugen activated his new sharingan while he closed in on the village entrance. It was shockingly blue with 4 tomoe!!!!

----------------------

6 months earlier Mugen had already collected many emotions and memories of other people in the war. Their pain, suffering, guilt , loss and many emotions were sealed within him. He used his three tomoe sharingan to intrude into their minds and take them. It was necessary for his Mangekyo sharingan super ability plan. He was still not sure it'd work but he wanted to try anyways. He would exe cute phase 2 soon. But then that leaves the evolution plan. He wanted to surpass the base three tomoe sharingan while at the same time not advancing to the mangekyo.

He had finally could a clue in an ancient ruin of a lost civilization. There was next to nothing left but he put together a few words. Their people had apparently wanted to cut off their human ancestor genes and become a new superior species. In their pursuit, they drove themselves to extinction. Mugen was inspired by then to cut off Indra's or perhaps kaguya's genes. But making a hypothesis and carrying it out were two different things. He already possessed three tomoe at age five, now he was twelve and no progress.

So he decided he was use the combination of extreme pain and his kekkei tōta to break his DNA chains. He formed microscopic ice needles and stabbed the organ in his head that was responsible for the sharingan and also his eye tendons and nerves. He infused the elements of wind, water and yang that created his ice into his eyes. Granted it hurt enough to make him scream louder than a pig being slaughtered but he endured. He also has a 90% chance of becoming blind or an idiot but he risked it. No pain no gain right.

Several days after when he was beginning to lose feeling in the parts he stabbed. He panicked. This obviously meant he was failing.

"Is this it am I going to become blind or even worse a retard." Mugen said helplessly . But even if he were to die he would have no regrets he chose this path.

He was suddenly immersed in darkness. "Have i ... Died once more?" Mugen sighed.

It was then suddenly that a mysterious thing appeared. They were chains shaped like DNA , each of them had three parts and a different oppressive feeling. They were red, white and brown. He touched the red part of the chain and he 'dad's indra: he gave off an imposing feel. The white was not hagoromo but kaguya. She felt God-like and indestructible. The remai ning brown was unlike the previous two. It was profound and mysterious. It was like the origin of all things. The boundless and indescribable feeling akin to a universe and the unknown was emitted from this seemingly ordinary brown. Mugen figured out what it was, the God tree.

Mugen felt that he was just a tiny any before those three sensations.

Mugen felt entrapped and helpless against them. "What can I do to them?"

Mugen will was crushed into tiny fragments.

An unknown amount of time later.

White figures appeared before him

It was Rikuo not just him, Ichigo, Reborn, Rihan nura , all the anime characters he thought were cool appeared before him, "Is this all you have ..... Pft.. You don't have what it takes to be the star of the show."

Mugen remained still. Naruto appeared, "I will never give up that is my nind o, my ninja way !!!!!"

His mother, Pakura ,Tsunade ,Kurenai ,In o , and other vague femine figures appeared. Wordlessly they pushed him forward.

Mugen smiled, "I can't very well be shown up by the rest,not when I am the main character this time around. Especially that Naruto. I will not be restrained!!!!!!!!" Mugen shouted and attempted to break out of his shackles but to no avail. Yet he didn't give up. His w ill condensed into a gigantic ice sword it cut at the chains, it barely nicked one of thousands binding him. Mugen continued to cut and hack non-stop. For what seemed to be centuries later, he cut through one. He continued in his assault for what seemed to be an eternity. He had finally cut through all of them.

Spending such a long time alone though, it was in actuality fake, his mind was tempered.

Power filled his consciousness. He returned to the real world. His eyes were filled with power he felt he could destroy the sky by just glaring at it, of course this was just his misconception. He looked at a reflection of his eyes. They were deep blue with black tomoe. It was a new sharingan.

Later Mugen tested its abilities. Even though it was blue, it has showed no signs of having glacial powers. The ability it gifted him was enhanced senses. His sight was already enhanced and didn't change however his touch, smell, hearing, taste and most importantly his sixth sense of intuition also seemed to enchance. He was expecting something overpowered but in a way these were overpowered he was satisfied with it.

----------------------------

Present day

Mugen merely activated it to look at the village on a whim. He felt many things he could not before. Though with his advanced senses even now it was too much to handle. He was like a werewolf. He could even smell their not completely exterminated body odour. It was way too much information. He DEFINITELY did not want to know most of them so he kept his eyes deactivated.

"Stop right there state your name, purpose and affiliation"

The guards at the gate stopped him. They could sense an extraordinary bearing from him and knew he was definitely a ninja.

Mugen looked at them.

"Mugen uchiha, returning home, konoha anbu and ..... I forgot the rest."

"Wait you're the secretive Blue eye d Frost reaper!!!!?" They looked at each other gulped and exclaimed .

Mugen tilted his head in puzzlement. How do they know him. He purposefully wore a mask and concealed himself. Then it came to him, that gossipy old man. It was the same with naruto hosting the nine tails. couldn't he hide the truth from them even a little bit. That damn old man.

Mugen knew it wasn't his place to judge the old man so he let naruto's case slide. He wondered if he should interfere. He had timed it perfectly and the nine tails would be arriving a week or so from now. He remembered naruto's birthday.

He decided against interference. Naruto's suffering is what made him into a great ninja. He would leave things as is. He had considered taking nine tails yin half but he wanted to climb up himself. He was at the threshold of kage level and his chakra was immense. Her was sure he surpassed kushina and naruto.

But then he did something to reduce his strength. In accordance with phase 2 of his Mangekyo sharingan plan he did something extreme. He created 25 glacial clones and had them all go on a journey in different directions. He wanted to experience new things and borrow new memories of pain, anguish, love etc from people he met in his journey.

He planned to seal all his memories and theirs; imprison himself in the coldest place possible and unleash all those emotions and memories at once saving his for last. He though that maybe perhaps and 'what if' that would increase the power of his abilities. Some theories involved personalities and the feelings and condition before awakening , perhaps it was all of them , who knows but he wanted to try. He liked his personality even though he was far from normal in that aspect and as for conditions and feelings before; that's why he was going to find the coldest place he could.

His clones had their chakra evenly distributed and perhaps due to being created by a kekkei tōta ,they far surpassed shadow clones in flexibility, durability and perhaps other ways he hasn't found out yet. They were completely separated from him but he gave them his decree and after they died they would return their experiences to him. It was like he was 26 at once. With that being said his chakra was at mid-chunin level and he couldn't do any big moves whatsoever. He still had his battle experience however, he was confident he could take down kakashi. He never relied on his sharingan too much before but in his current condition he had no other choice. He was highly skilled but he lacked chakra. This could be considered another type of training. If he met anyone like kisame; he would have to take them out quickly or he would be in big trouble.

While he was average now and could barely maximise his natural talents, he welcomed the challenge. In the village, while nothing is for certain, he wouldn't need that much chakra. He was also going to find some subordinates all with kekkei genkai so his sealed state should give them some limelight. Kimimaro was very dependable, strong and blindly loyal, he was just perfect as a subordinate, he could trust him fully. He planned to locate the kaguya clan soon.

strong

"Sir um ... Can you hear me... Oiiii!!!!!" He said in Mugen's ear.

Mugen surfaced from his ocean of thoughts to find someone shouting in his ear. Mugen tilted like a tree enduring a storm. He stayed silent and closed his eyes. A shadow loomed over his face. His demonic blue eyes appeared, A demon shadow appeared behind him. He glared at the ninja who was responsible for guarding the gate and shouting in his ear.

The ninja felt death was looking at him, he gulped and brought out a box, "Please for five my rudeness, this is the most delicious lunch ever. I had stood in line in the next town over to get it. This box even traps it's heat so it's good as new. Please accept my apology and spared me!!!!!"

"You idiot you're doomed there's no way that'd work. Rest in peace I'll take care of your wife." The other guard said strongly at first slapping him with an object, later becoming smug with the last sentence, thinking of the man's wife.

" Really??!! " Mugen's shadowy black figure with his demonic blue eyes seemed to towers over him.

"Yessss... Sir i guarantee" he stuttered a bit.

"Reall y???" The voice of death sounded again mugen's figure seemed to extend into the sky .join

"Y...e..a..eh..eh eh yes " he said fearfully.

Mugen took the lunch opened it and already started eating, "Okay" he said.

"Wtf!!!!!!😱 that actually worked!!!!" The other guard exclaimed .
