Uchiha Zeref: why Naruto don't use the mangekyou to win? and what's his mangekyou's abilities?

The same reason Kakashi rarely used. Bad for eyesight and large amount of chakra consuming, especially not being an Uchiha.
About his abilities, one is in this chapter, another will be revealed later.

I would like to state something here, as having large chakra reserves cannon Naruto was weak in Genjutst, so in this story also he is not very proficient in casting illusions, stronger mages will break them with little effort. Sure using Mangekyou is another story.

Chapter 13 – New guild

"It's far from over, Jose."

Red chakra started enveloping Naruto's body as strong wind occupied the room. The ground beneath him cracked and small stones pushed backwards.

"It looks interesting." Jose laughed as his eyes turned black. "I will show you the difference in our power insect. Dead Wave"

"Katon: Gōkakyū no Jutsu (Fire Release: Great Fireball Technique)"

The two attacks collided and before the fire could vanish Naruto again formed some seals.

"Fūton: Daitoppa (Wind Release: Great Breakthrough)"

The wind gave life to dying fire as the combined attack burned down all the darkness magic and hit Jose. "Using both wind and fire magic to complement each other like this, you truly are something. Too bad you have to die." Fire burned down and Jose was standing there unharmed.

"Taju Kage Bunshin no Jutsu (Multiple shadow clone jutsu)"

Forty of Naruto appeared completely filling the room, each handing a Rasengan in their hand ran towards Jose. Jose already familiar with the destructive power of those blue balls decided not to take any chances as he moved his hand in an arc. "Dead Pulse" the blast occurred which followed Jose's hand movement and all the clones vanished. But the real one was already nowhere to be seen.

Before Jose could do anything Naruto came out of ground beneath Jose and punched him in the chin making Jose lose his ground. Jose instantly returned the favour with one hard punch of his own.

Naruto stood up and prepared his modified version of Rasengan. Jose found the screeching sound a little nerve wrecking. Naruto used Hiraishin to appear behind Jose and attacked him, "Futon : Rasengan".

The stronger Rasengan was capable enough to push Jose back inspite of his magic protecting him. Naruto took the advantage as he bombarded with a fury of attack. Jose tried to hit Naruto but he vanished with a yellow flash.

"It seems you are out of breath." Jose smirked as he continued, "I found something interesting, you use some teleportation magic which is indeed fast, fastest magic I have ever seen. But there's a catch, you need these things" He picked up one of his kunai and shattered it, "to teleport unlike regular teleportation magic which cancels the advantage of your magic being more fast. IT'S OVER"

He created numerous phantoms which destroyed each of his kunai and captured Naruto by coiling around him. Naruto saw the tide changing within a second as he found himself unable to move and neither there was any kunai left to teleport to.

"Don't struggle. These are not just any regular phantoms but these devour on hatred. And I can sense in your power, there's lot of it. The more hatred it eats the stronger it gets and there's only one way to escape this, when there's no power left in you for it."

Naruto felt the crushing pain as the grip tightened. Jose continued, "You know what other interesting thing I found? Before every attack you used, you used your hand for something. I don't know what magic you use. But let's see what you will do when I break your hands."

Naruto screamed in pain as the bones in his left hand shattered in pieces.

"Oh there's one more thing." Jose smile turned sadistic as he continued, "Your eyes. Your disgusting eyes. You think I didn't notice? One thing I learned from my experience is to never look into weird eyes and yours sure top them all in weirdness."

"So now, let's remove these eyes before killing you." Suddenly all the phantoms vanished and Naruto fell into the ground. Jose raised an eyebrow, "What? Already out of all the power?"

Few minutes earlier, inside Naruto's mindscape.

Kyuubi felt as his chakra was pulled from him, he knew the reason and he didn't want any mage of all things doing that. He knew no matter how much chakra he pulled, his magic was not capable of breaking the seal made by Yondaime hokage. It was one of the few times Kyuubi was impressed by Naruto, as currently he was not like those spineless Jinchūriki he had before but Naruto was doing exactly what he expected a strong person should do. That was the reason Kyuubi gave his chakra to fight without trying to take control.

Kyuubi saw only way to stop this. He suddenly stopped all of his chakra flowing. With no hatred filled chakra to devour on, Phantoms vanished dropping Naruto to the ground.

Outside in the real world

Jose picked Naruto up and held him by his neck, expecting him to be unconscious. 'I can't move. But…' Naruto thought, 'but right now neither is he.' He decided to put all his remaining chakra to one final bet. Jose threatened him as he laughed. But when Naruto opened his eyes, he realised the difference in his eyes from before.

"Mangekyo Sharingan: Tsukyomi"

Jose found the light getting absorbed in Naruto as he disappeared along with the light, making the whole surrounding dark. The darkness doesn't prevail for long as the vast limitless area filled with red light coming from a red moon. He questioned his surrounding founding himself in a whole new place.

Naruto came out of the ground followed by various chains which held Jose at one place. The broken hand seemingly fine as he used the very hand to drive a sword through his chest. The expected blood never came out but the pain was nonetheless extreme.

"Where are we?" He glared at Naruto.

Instead of saying anything Naruto once again stabbed in the stomach. With each stab one more Naruto came into being as they together tortured him. After getting stabbed various times in different places which seemed to continue for hours, Jose finally snapped as he screamed and everything became dark once more.

In real life Jose and Naruto fell to the ground. For any outsider, it didn't look more than a second. Jose was on his one knee with his eyes widen in pain and confusion. On the other hand Naruto was panting heavily holding his mask over his bleeding eye which could be seen through the broken pieces of his mask. The only thought he had was, 'How did he break Tsukyomi?'

Jose was Wizard Saint after all. The sheer amount of magic he used to counter Naruto's Tsukyomi which was already on the verge of collapsing due to lack of chakra made Jose free from the supposed ultimate genjutsu.

Gathering his bearings Jose pushed himself to stand as he said making a disgusting snarl, "You are dangerous. I really can't let you live as my enemy." Naruto was one of those few who had made him scream since his childhood, although that was not in reality but Jose didn't know.

Naruto felt a familiar presence approaching as he felt his body getting some strength back. Jose looked above Naruto's head still filled with rage, "So you decided to come, Makarov. Better that way. I will kill you both together now."

Makarov turned his attention towards Naruto and said, "You have done enough, leave the rest to me."

Finding his chance Naruto disappeared. In the near corridor, he placed his back against the wall as he put one small pill in his mouth and swallowed it. He cursed himself for not learning how to make chakra pills back in Elemental Nations, but then again he was not even sure whether he could find its ingredients in this world. It was a pill developed by Susan which helps in regeneration of dead cells a little, gives some strength and removes the fatigue from the body, which in all means chakra development in a little faster rate than normal.

He slid taking the support of wall and sat down. 'Dammit! I couldn't even beat one mage and how I am supposed to face Grimoire Heart?' He punched the wall with his right good hand.

Back in the fight between Jose and Makarov. Makarov commented on the condition of Jose, "We should put an end to this. It seems you are already tired."

"The last one depleted little over half of my magic, but I am sure you are also not fully recovered in such short time. So still I am more powerful than you Makarov. After I kill you, I will take my time in slowly killing him and everyone he holds dear."

"You are not getting anywhere from here, Jose. Enough talking, let's finish this."

After taking few minutes of rest Naruto picked himself up and started walking towards from where fighting sound was coming few minutes back. While sitting and waiting for some of his chakra to regenerate, he saw from the window the blast and fire coming from the opposite side.

He slowly entered into one room which had already seen a fierce battle. He looked at the phantom mages lying unconscious around but he stopped as his eyes fell into one particular lying mage. The intense killing intent his body leaked marked his presence in the room as one pink haired and one blond mage took notice of the masked person totally covered in wounds and bruises, not knowing whether he was an ally or enemy they somehow stood up.

"GAJEEL" Naruto roared as he started moving towards the lying black haired mage. "Finally. Finally I found you."

Natsu, the pink haired mage tried to stop him but stopped as he looked into his eyes. Without any magic left in him, it was just as easy for Naruto to put him into an illusion like a common people. Natsu found himself unable to move. "What happened? I can't move."

Lucy scared of what happening tried to call her spirit by taking out her key but same fate fell on her. "Don't get in my way." Naruto said to them as he stood over Gajeel.

"Who are you?" asked Gajeel.

Without saying any word Naruto concentrated his remaining chakra in his right hand as lightening started enveloping it which followed by the chirping sound of birds. "My team mate learned this so that he could take his revenge, it would be great if I took mine with the same. And knowing you are Iron Dragon Slayer, I don't think a knife will kill you."

Unable to properly move Gajeel just lied their and saw as Naruto thrust his hand towards his chest.

'Naruto, try not to kill unless it's the only way'

Naruto stopped his hand and cursed his luck. 'Why am I remembering this now?'

He stood and looked at the iron dragon slayer, "It would be pathetic to kill you like this." He took out a bag and dropped it onto Gajeel's chest, "Treat yourself with this money, then I will find you and beat you to death and will again wait for you to get healed." Saying that he disappeared in the swirl of air.

Natsu and Lucy both fell to the ground, "Just what happened?" Lucy asked no one in particular.

Gajeel felt his chest going numb after being in contact with the lightening. A small tickle of blood was present on his chest. He felt something cold on his forehead as small breeze flew. He touched to find sweats. 'Sweats? Was I scared?'

For the first time in years, he was scared. He didn't know why he couldn't move. Was it due the fear which crawled into him or was it just lack of any power left in him. He left the thought, thinking the cause to be the second one.

He turned his head to look at the Fairy Tail mages who were clearly confused, while afraid in case of the blond mage. He didn't knew who he was. From the look on the Salamander and Blondie, he was not a Fairy Tail mage. He just came utterly beaten and threatened him in a way he hadn't heard before. Remembering his eyes, finally he came to peace with, 'It seems I was really afraid for a second.'

Naruto looked from one of the roofs as the bright light enveloped everything and everyone. With each phantoms destroyed, he knew the fight was over with Makarov as the victor. As the light died, he found enough strength to move again but decided to take a little more rest.

He was sitting on the roof of one of the buildings near to the shore, holding his broken hand with other good one while the broken mask was lying to his side.

Gathering all his power and thoughts he stood and turned towards the hospital. Not because of his own condition but the priority being Levy. He had yet to see her after getting back to Magnolia.

Several days passed after the assault of Phantom Lord. Fairy Tail was busy building up their new guild building. Unknown to all mages one single person was seating on top of a high unfinished wall. He looked at the ruckus beneath him while putting his long hair behind his ear with his good hand while the other was covered in the plaster cast.

For past few days after the things settled up with council and construction started, Naruto made a habit of coming there as he had nothing better to do. Watching his surrogate sister who was discharged by the time and helping with the construction was also rather good for him.

Without looking behind he said as he felt the presence, "Hello Master. How is the guild doing?"

"You could ask this directly to them also." Makarov said as he took the seat beside him, holding a large mug of beer.

When no reply came he let out a audible sigh, "They are doing fine, no one was severely hurt. I can see you care for guild just as any other member. It's a pity no one knew who saved them when I was not around. Erza was curious about you, asking me if I know you."

"Working from shadows, that's nothing new to me. Moreover, what did you tell her?"

"The same answer you told me to say, 'an old friend'. She was impressed least to say."

After what appeared to be a long time Makarov continued, "So what now? After meeting with an 'accident' and getting your hand broke?"

Naruto heard Makarov putting emphasis on the word 'accident'. "That's looked like a good excuse at that moment for this broken hand." He said as he lifted it above. "Moreover I got some time to read and try a few things."

"And that may be?"

"This" Naruto handed him a small crystal. Seeing Makarov raising an eyebrow he continued, "It's a lacrima as you can see. It's connected to this tattoo." He said as he showed a small tattoo on his upper chest-lower neck region.

Makarov narrowed his eye to get a better look, "two?" as he saw one more tattoo little side to it which spelled 'one' in their language.

Naruto continued his explanation, "Levy was hurt because I was not around and I am not expecting myself to be with her all the time. So I made this, so that she can inform me if she's in danger by putting some magic in it. The other one I am giving it to you."

"That's very considerate of you. No offence, but I don't think I will be asking someone outside of the guild for help."

"I was expecting that." After a moment he said, still not removing his eyes from the members below, "Susan told me something once, just after I joined the guild." Seeing from the corner of his eyes that he had Makarov's attention he continued.

"She said that from that time all of the Fairy Tail is my family and made me make a promise that I will look after this guild like a family. I don't know what a family is, I don't know what a family supposed to do together. But I am sure they do everything they can when their family members are in danger."

Makarov looked at the emotionless eyes of his, unable to draw conclusion whether the reason of him saving them was just that promise or something else.

"Whatever you are seeing below that's what a family do. Helping others not only when their life is in danger, sharing not only the bad things but also the good things in their lives. Family is what you were to Susan and is to Levy. What family do is whatever you used to do there."

For a moment Naruto's eyes widened for a moment as Makarov saw a glint of emotions in his eyes as he smiled.

Naruto kept his eyes below at the people who were busy doing their work. He saw as a silver haired girl gave drinks to other mages. He remembered her, eldest of the take-over siblings-Mirjane. His eyes sifter to other sister who was also helping others, currently taking a form of an animal-Lissana. And then there was the last of the sibling, Elfman who was continuously shouting about being a 'man'. He was really getting irritated by that.

He noticed few people missing, particularly one - one who was easy to find with her bossiness and her scarlet red hair, beautiful just as his mother's. Thinking something bad he asked Makarov, "Master, that redhead. She is not here. She was in a very bad shape against Jose, did she overworked herself or something in the construction?"

It took him a second to register, 'Is he really asking for other's well-being?' And then a teasing smile emerged onto his face as he said in singing voice, "Erza-chan?"

Naruto flinched at the voice but nodded.

Makarov laughed, "There are others also who are missing today, but you are only concerned about her. Don't tell me you have faller for the Titania."

Naruto looked at him as he had grown a second head.

Seeing his oblivious side Makarov smiled as he continued, "Yeah she's fine. Erza along with some others had gone to some resort hotel."

Getting up he dusted as he turned to leave, "Well Naruto, I will be leaving. Once again thank you for what you did."

'What I did huh?' He looked at his broken hand as he remembered Kurama's word. 'I forcefully stopped my chakra supply into your body to get rid of that magic. It will take few days before the supply can start.'

He sighed, 'Although Kurama's chakra has started flowing slowly but it will take some more time for this hand to get healed.'

Birds chirped to life as the morning light fell on earth. In one apartment, Naruto woke up as he went to the board in different room. The apartment was medium sized with two bedrooms, one which he used as a bedroom while the other mostly remain closed, containing his kunais, information about various mages and guilds and other things sealed in various seals and scrolls.

He plucked one paper from the board as he shook his once broken hand. He read the contents and seconds later it burned to ashes. He murmured the name of guild written on that paper, "Deadly Eagles."

Deadly Eagles was one of the dark guilds under the bigger fish known as 'Phoenix Fire', a stronger dark guild which was currently gaining a lot of names and attention. Nobody knew where it was located, neither had he any luck from its other underling guilds, which he had already destroyed. Phoenix fire, containing large number of mages, but most problematic were the group of eight who called themselves, 'Eight wings of Phoenix'.

First he had to find about Deadly Eagles and it was his last chance to find the Phoenix Fire. And from Phoenix he can learn about one of the main thorn - 'Oracion Seis', one of two partner of Grimoire Heart in Balam Alliance whose main objective was to resurrect Zeref.

He clenched his fist after remembering those names.

For the whole day luck was not on his side. Unable to find anything about them he decided to take a break to get some dinner. He went inside the nearest bar which also provided food.

He waited for his order to arrive as he scanned the inside of the bar. Mainly males were present, to relieve some stress after the day's work. He saw as one woman sitting on the corner winked and smiled at him only for him to ignore.

As soon as his order came, he started eating.

Suddenly doors were thrown open as six people came inside, shouting and beating anyone on their way. "Hey lady bring us some foods and all the jewels you have." The supposed leader barked as he moved towards the barmaid. He outlined her face as he continued with a look of lust, "And help us carry those jewels back to our guild. We all will reward you or else..." He showed her his gun, "or else I will kill you and your family."

Irritated of being his peaceful meal interrupted after having a really bad day, he decided to have a glance at those. The guild marks which was supposed to be well hidden under the shirt was not so well hidden as Naruto's sharp eyes got a glimpse of that.

He smirked thanking his luck as he said peacefully, "Deadly eagles?"

They turned to him and stared at him for some time before sating, "Yeah. So?"

"I want to know where I can find Phoenix Fire."

"Heh. Is that so?" the leader mused.

"You have three seconds" warned Naruto. "Three"

They just laughed at him as he continued his counting, "Two"

"One" Naruto stood up and vanished as the leader heard thumping sound from behind. He turned to look all his partners lying on the ground.

"So, where is it?" Naruto asked calmly.

With a shout the leader pointed the gun at him, "Gun's Magi…"

Before he could complete Naruto twisted his arm as he dropped the gun and screamed in pain, "Stop, my hand will break."

"Where is it?" He asked once more threatingly.

"Ok ok I will tell you." As soon as Naruto learnt everything he wanted, he twisted his hand breaking it. He put his hand behind the leader's head as he slammed it on the counter, busting it open as blood started flowing.

After taking out the jewels from the mages Naruto gave it to the barmaid, "Thanks for the food. Keep the change."

She looked at the man leaving who had saved just saved her and gave her the best tip of her life, 'Keep the change? He gave me twenty times his bill.'

As Naruto was certain he was not in anyone's sight he removed his henge as he transformed once again into his own self. In order to hide his identity he had transformed into some random person.

Taking out the scroll where he had locked his mask and weapons, once again he was ready to strike the evil.
