A figure could seen standing on a cliff looking at the scene of nature before him.
The figure jumped down towards a small pond before filling a canteen with water before looking at his reflection.
The figure had black, spiky neck-length hair with two bangs falling at the sides of his face. His left eye was blood red with three tomoe spinning lazily around a black dot. Meanwhile his right eye was different.
His right eye was purple with three rings in it, with each ring having two tomoe in them. This figure was obviously Uchiha Izuna.
He had left Sasuke with Orochimaru as was ready to leave this world. He was surprised at how easy it was to obtain the rinnesharingan.
He had figured out how Sasuke got his rinnegan. Sasuke is the reincarnation of Indra, the first son of the sage of six paths. While Naruto is the reincarnation of Ashura, Indra's younger brother.
Together Ashura and Indra's chakra combine to form the sage of six paths chakra. When Hagoromo transferred his chakra to Sasuke, he transferred Indra's chakra causing the change in his eyes.
So essentially if he could stimulate Sasuke's cells with Naruto's cells and infuse it into his eye, he could essentially gain the rinnegan. Obviously he didn't have Naruto's cell but he had the next best thing. Orochimaru had been experimenting with Hashirama's cells so it wasn't hard to get some samples.
Of course he didn't do any of this without confirming with his system. He didn't have any clue on how to fuse the cells together so he used the system to fuse them at the price of his remaining points.
At the moment he had zero system points but he was okay because it was worth it.
He was now 14 years old. The most powerful 14 year old shinobi. The original reason he went with Orochimaru was to learn the sword style that Sasuke used. And also Orochimaru had a lot of lost jutsu.
'System, what do I need to do to leave this world.'
{Host doesn't need to worry. Just leave it to the system.}
'Do I get to choose which world I travel to?'
{Host's first world to travel to, will be chosen at random. The host will be allowed to choose after first world jump.}
'I should have expected it. I'm ready for the first jump.'
He wondered which world he would get.
{Standby...transferring host.}
White light surrounded him as he disappeared from his position.
~~~~~~~~~~~~Unknown~~~~~~~~~~~~
When the light disappeared, he found himself in a place that looked like a storage warehouse. At least he knew that this world was somewhat advanced.
He changed into the outfit he got around the time he was reborn in the Naruto world. Sasuke's outfit that he wore during the war. It fit him perfectly, after all he looks exactly like Sasuke.
Surprisingly the outfit came with the kusanagi sword. That is a pleasant surprise. He body flickered to the roof. As he looks out at the city, he could see people walking on the streets. Cars driving around occupying the roads.
It looked familiar but he could put his finger on it. It wasn't until he sighted a billboard up ahead that he knew which world he was in. He facepalmed as he looked at the billboard.
'Of all the worlds and I end in my hero academia.'
On the billboard was an enlarged picture of All Might with that ridiculous smile on his face and a catchphrase written "I AM HERE" beside him.
'System, what part of the story am I in?'
{You are in the story a few minutes before the USJ incident.}
'Putting me on the spot at such a critical time for them doesn't help me decide on what to do.'
He had half a mind to just walk away from it, but an opportunity could come from this. People in this world aren't strong. The only people that could even challenge me, even if just slightly, are All Might and All for One.
Leaping from rooftop to rooftop, I see an isolated civilian. I dropped down in front of him before putting him under genjutsu. He went through his mind until he found what he was looking for.
As he headed to UA, he made sure to stay hidden. All might should be in the principal's office before he rushes to USJ. When he rushes there, Izuna would follow him. And sure enough as he got to the US building, All Might dashes past the UA gates.
His speed is impressive, maybe mid-jonin speed. Nowhere close to Izuna's speed. Trailing All Might, he finally arrived at UA. Using the distraction that All Might had made, he snuck into the shadows, waiting for the perfect moment.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
All Might had just saved Bakugo from Nomu's punch. Tomura then starts his talking.
Tomura:"It was to rescue my companion. I had no choice. He was about to punch me with everything he had, you know. You know what, All Might? I'm angry. Violence only breeds violence. The world will this, once we kill you."
As the students and All Might listen with rapt attention, a voice rang out as someone came out from the shadows.
???:"Shut up."
The figure has black, neck-length hair with two bangs framing the sides of his face. He wore a grey, high collar short sleeved zipped up jacket. He wore black anbu pants with shinobi sandals. A dark blue cloth was tied round his waist by a purple rope. A sword hung by his hip as he walked in between All Might and the Nomu.
What shocked all of them was that he looked no older than 15. This is obviously Izuna.
All Might:"Young man, I don't know what you're doing here but this is a dangerous fight. I suggest you leave this to me."
Izuna continues looking at Nomu while answering him.
Izuna:"All Might...shut up. I don't care what you think."
The students and even the villains were now shocked. No one had witnessed someone who wasn't a villain talk to All Might like that.
Tomura:"Nomu, kill this cocky shit."
Before anyone could react, the Nomu had already launched a full power punch towards Izuna, blowing dust everywhere and causing a shockwave to spread.
All Might:"YOUNG MAN!!!"
All the students were afraid for Izuna.
When the dust cleared, the scene in front of them shocked them to the core.
Izuna could be seen with the Nomu's fist caught in his palm with a casual expression on his face.
Izuna:"Is this all."
Tomura:"YOU'RE CHEATING!!! YOU HAVE TO BE CHEATING!!! NOMU WAS MADE TO KILL ALL MIGHT!!! THERE'S NO WAY YOU'RE STRONGER THAN ALL MIGHT!!!"
Izuna:"Pathetic"
He kicks the Nomu away with a chakra enhanced kick, before whispering.
Izuna:"Amaterasu"
Black flames burst out on the Nomu's head.
Tomura:"You don't get it, do you? Nomu will regenerate from anything you do. Your flames won't do anything."
Izuna stays silent, which Tomura takes as him giving up. Tomura was about to talk again until,
Tomura:"What's this!? It isn't regenerating! What did you do!!!"
The Nomu finally burnt to nothing as not even ashes remain. It was silent until Izuna's calm voice pierced through their ears.
Izuna:"I killed it and you're next."
Tomura has a crazed smile.
Tomura:"You would t dare. You're one of those hero types, you wouldn't ruin ruin your chance to become a hero by killing me."
Tomura's smile turned to fear as Izuna unsheathe his sword and walked towards him.
All Might:"Young man, don't do this!"
Before Izuna could get close, the doors explode as the backup arrives with Tenya Iida leading them. Izuna looks at them in annoyance before sheathing his sword.
Using that distraction, Kurogiri made his way to Tomura, teleporting themselves away. But not before Izuna threw a kunai at the detachable hand covering Tomura's face. The hand fell as the portal closed.
Izuna was walking away when one of the heroes held his shoulders. He spoke in a cold quiet voice, but it was clearly heard by everyone present.
Izuna:"If you value your life, take your hand off me."
