Ninja's hero

Itachi looked left, then right, then left again. Then right one more time. He closed his eyes and sharpened his other senses, there was no sound of any movement, there was nothing for miles around. He opened his eyes, there wasn't any movement either. Hell there wasn't even a genjutsu activate on him. There was nothing around him.

Except this small child.

This small green haired child.

He was only Sasuke's age of four, Itachi couldn't really boast being an adult at nine but even so he knew a child this young shouldn't be alone anywhere, let alone a forest. Least of all the forest of fucking death. "Are you okay?" He asked the boy. The green haired boy seemed to wipe his face and looked up at Itachi.

"Yeah I'm fine mister, sorry for troubling you,"

"Alright now tell me the truth," Itachi pulled out his kunai and pointed it to Izuku. "Who are you?" The boy turned ghostly pale and his eyes began watering.

"I'm," He sniffed, "I'm Midoriya Izuku, please don't hurt me,"

"Why are you limping?"

"I'm,"

"Don't lie,"

"Katsumi and Izumi hurt me," The boy quietly admitted.

"How did you get here?"

"I was running away from them, because they were being mean," Itachi tensed, there were people around. Resharpening his senses he tried to hear anything. But there still wasn't anything, not even a second heartbeat. But there was an overwhelming sense of chakra emanating from somwhere.

"Why were they being mean?"

"Because I want to be a hero, even though I'm a boy,"

"You mean a shinobi?"

"What's a shinobi?" Alright, not a brilliant start.

"Why can't you be a hero?" Itachi decided to press on, repressing his confusion for a moment.

"Because I'm a boy, and that means I don't have a quirk," Okay, pause. A quirk? Isn't that just a personality trait? Clearly this boy was either messing with him or he genuinely had these things in his village.

"What village are you from?"

"I'm not from a village, I live in Musutafu, a part of Tokyo," This kid had to be messing with him now. "Where am I? This isn't the forest me and Kacchan play in," The boy began getting scared.

"You are safe for the moment, do you remember how you got here?"

"I ran through the trees, it looked like a door," That meant the boy could return to this Musutafu, Tokyo area. "Are you a hero?" The sincerity gave Itachi pause.

"No, I'm not a hero, I'm an Anbu, a very powerful shinobi, why do you want to be a hero?"

"To save people like my mama! She saves everyone with a smile!" 

"Alright, so why not train to be a shinobi then? You've got a lot of chakra, more than an average person,"

"Chakra?" Itachi internally facepalmed, this kid made Sasuke looked almost gifted. "Is that a quirk?" Sensing a foothold he tried.

"Yes, it's a very common quirk in the place, almost everyone had chakra here, it lets them use ninjutsu," The forest haired boy began to sparkle.

"Can you teach me how to use it?!" Itachi thought for a moment, this boy was clearly underweight from the clothes hanging off him and injured from the burises he failed to hide.

"Very well, but I can't do it when you're like this, come, we can eat first then tend your wounds," He began leading the child.

"This is my hidden spot, it is where I come to train and rest, it is where I organize my thoughts," A small campfire was ready to burn next to a very rudimentary shelter. Izuku smiled and limped over to a log that acted as the seating by the fire. Itachi quickly weaved some signs. "Fire style: Fireball jutsu," Lifting his hand with his middle and index fingers extended  to his lips. A small burst of fire ignited just above his fingers and flew to the campfire, causing it to start burning and crackling. "Alright, there's some roasted fish to eat," The smaller boy eyed to skewers resting around the fire. "Lesson number one, a shinobi can not be picky when it comes to eat, you don't know when a battle may start so you eat everything you aren't allergic to," Izuku took a fish and began eating it slowly. "You shall learn to enjoy it," Itachi shook his head as Izuku pulled many faces eating the fish. Another body soon entered the area and dropped into a fighting stance. "Shisui, stand down, he is four!" The greenette dropped the fish and began bowing in apology. His talking much faster than anyone he'd ever heard. There were glimpses of 'sorry' over and over again until Itachi stepped forwards. "Don't worry Izuku, this is Shisui my cousin,"

"Itachi, there's a massive chakra presence,"

"It's Izuku," Itachi shook his head "I've done every check I can, this child is the only thing present for miles around here,"

"Be that as it may we need to know,"

"Look at him Shisui, he's barely Sasuke's age, he's no threat to anyone, he's underweight and already bruised, the boy doesn't even know what chakra is, he thinks it's something called a quirk?"

"So you found an immensely powerful blank slate?"

"I'm not taking him to Konohagakure, not into Danzo's hands," Being an Anbu Itachi knew the dangers, being nine he was stubborn to the end. "I want to teach him, he came here running from attackers and doesn't know how to fight back," The (Barely) older boy's faced softened.

"Alright, hey Izuku was it?"

"Yeah?"

"We're going to get you patched up and we'll start teaching you ninjutsu, and some taijutsu, you want to learn?"

"Absolutely,"

"It's going to be difficult, it's going to leave you sore," Shisui warned.

"I don't mind, anything to be a hero!"

"Told you," Itachi smirked as Shisui stared completely baffled, "But it's a migraine for another day," Both nodded and chuckled before sitting either side of Izuku.

"Sensei you know I can detect you both right?" Izuku sat leaning over the cooking some fish. "I'm not as weak as I once was," That was true. In two years they'd been training Izuku had grown immensely, his taijutsu, ninjutsu and shurikenjutsu were all incredible, almost better than Itachi at his age. In fact his chakra was so large, potent and concentrated they had decided it was primal chakra, a very rare unspecialized chakra that gave Izuku an affinity for, well, ever chakra nature. Both older boys landed silently on the other side of the secret clearing. "What training are we doing this weekend?" Itachi smiled, over the last two years they'd been training every weekend and a few weekdays in an odd yearly cycle that Izuku claimed was due to Alderra elementary school. Whatever the fuck that was. During that time their relationship had grown into an almost brotherly one both of them training Izuku as best they could, both being Anbu meant Izuku was trained pretty damn well.

"This weekend we're going to be going on a little trip," Itachi offered, "You're going to become a real shinobi of the hidden leaf village,"

"Wait, we're going to Konohagakure?!" Izuku stood up, long since disappeared had the timid and shy boy replaced with a more confident humble one. "Alright!" he bumped his fist up. "Let's get moving," The three crouched before leaping into the trees. Itachi and Shisui both thought nothing of bouncing between the trees as Izuku raced just behind them, mumbling about his abilities going beyond superhuman, being faster than something called a sports car? Itachi and Shisui shared a bemused look, even after two years they still didn't have a clue about what Izuku's home world was like. They continued to bounce through the forest for a second. "Oi sensei!" Both looked back while Izuku seemed to catch up without effort and harmlessly tapped Shisui's shoulder. "Tag, you're it!" He flipped to smile brightly upside down before pushing off the next branch. Itachi leapt with more force away from Shisui as the eldest boy reached out.

"Can't catch me that easy Shisui!" Tag had been one of the games they had used to teach Izuku how to chain movements together, running up tree trunks, bouncing between branches and even substitution jutsu. Him starting a game was rare, only when he was in a fun mood. Itachi and Shisui had learned quickly how fun the game was in general. Laughter emanated from the three for the briefest of peaceful moments in the forest.

"Woah, this place is massive!" Izuku stood at entrance to the home of shinobi. "So where are we going?" The three walked harmlessly into the village. Itachi chuckled slightly as Shisui shook his head. "Come on,"

"Let's go to the park for a moment, I need to grab Sasuke," Itachi spoke levelly. Izuku had never met his younger brother but there had been conversation about the young Uchiha. The greenette admired Sasuke for drive to be a ninja like Itachi. They reached the small park and all stood at the edge. "Sasuke, come here, there's someone I want you to meet," Parents began leaving with their children slowly, each avoiding a particular blond boy in a swing. Something Izuku didn't fail to notice.

"Hey, who's that?" He pointed to the blond.

"That is," Itachi squinted and cursed silently. "Shisui. do you remember Minato?"

"Fourth yeah, why?"

"That's Naruto Uzumaki, his son," Shisui pulled away.

"And they treat him like that?" Both brewed in mild anger, something to talk to Third about. Izuku needed nothing more before calling over.

"Uzumaki!" He called out, the blond looked over to the waving boy. "Over here, come on," Slowly Naruto came over to them. "Hi, I'm Midoriya Izuku, you can call me Izuku!"

"Hey, who's this?" Sasuke complained.

"He just introduced himself Sasuke, you should listen more," Shisui scolded. "This is Midoriya Izuku, we found him a few years back and have been training him every weekend,"

"Hi Midoriya, I'm Uzumaki Naruto, you can just call me Naruto!"

"Then call me Izuku!" The greenette matched the jovial energy. "Sensei can he come with us? Please?" Itachi and Shisui nodded before the group of six began walking off. "So, Uchiha, what is Sensei like at home?"

"Lazily, just sleeps all the time, never helps me at all,"

"If you want I can help you?" Izuku offered merrily, "I mean I'm probably not as good as you but,"

"Okay! I mean getting to train with someone isn't something that happens often,"

"Naruto, you can join us too!" Both older Uchiha's paused and smiled as the blond's mood was lifted incredibly high. "Hey Sensei, can I train with these guys from now on? Pretty please?"

"Pretty please?" Shisui hummed "Well I guess so, but we need to go talk to Lord Third first,"

Minutes later the six stood in the Hokage's office while he pondered for a moment. "Midoriya?"

"Yes Lord Third," The greenette bowed "I am Midoriya Izuku, I am from a place called Musutafu, in a region called Tokyo from another world, I stumbled into your Forest of death two years ago and met Uchiha Itachi, I believe what I stepped through was a gateway of sorts, I have since trained under Itachi and Shisui Uchiha, I wish to become a shinobi of Konohagakure, I am skilled in Ninjutsu, Taijutsu and Shurikenjutsu, please let me join," The Third Hokage hummed for a brief moment before observing Izuku for another moment.

"Very well, we shall test you on your knowledge to see if you show promise as a Genin before we make you part of Konohagakure, is there any issues following your location?"

"No, I plan on coming into Hagakure as soon as I finish elementary school in my world, hopefully it shall only be two more years," Izuku bowed again, "Thank you for having me!"

"Thank you Lord Third!" Itachi and Shisui both bowed deeply while Sasuke and Naruto stood at the side  mildly confused.

Itachi stared ahead as he heard feet approaching. Izuku stormed into the clearing, his face the picture of rage angrily growling about his stupid fucking parents. Itachi didn't say anything until Izuku saw him, the anger vanishing instantly. "Sensei, what's wrong?!" He ran over and slid across the grass to the older boy's side.

"Izuku, Shisui died, he killed himself before people could come after his Mangekyou Sharigan," A small leather pouch was pulled from Itachi's pocket, "He wanted me to give them to you, so you could guard them, are you ready to accept them?" The greenette was obviously distraught. One of his Sensei's for four years just died. Itachi bit back tears as he continued, "The Uchiha were planning a coupe, that would've killed most of the villagers," Izuku seemed to put the pieces together quickly.

"No, Sensei, no!" Itachi was enveloped in a hug,

"I couldn't kill Sasuke, please, look after him for me," Tears fell down both of their faces. "Please,"

"I swear on my ninja way to protect him as much as I can, Sensei?"

"Yes?"

"Can you implant the eyes into me please?" Izuku laid down on the log facing the sky. Itachi stood up, wiping the tears from his eyes. Shisui had asked him to be strong for now, he could face the pain later. Right now his pupil needed him.

"Alright, but it's going to hurt," Pulling out a tag he prepared to knock Izuku out.

"You said that about my training, look how great I am now," Izuku chuckled before the tag struck him. Itachi began his work and opened the drawstring pouch. The process was not a long one however it was a delicate one. His body readily accepted the eyes as his own quickly and Itachi wrapped bandages over his eyes around his head. Izuku woke up not long after the procedure completed and clutched his face. "AH, fucking, ow!" His hands reached for the bandages. "Pain fades, pain fades," He repeated slowly.

"Izuku it's not,"

"I'll have to take them off eventually Sensei, so why not now?" The bandages slipped away and Izuku stared up at the bright light for a moment. "Ooh, that stings but it's fading already," Looking over at Itachi he caused the teen to gasp.

"Impossible, you're not of the Uchiha bloodline," 

"What? WHAT?" Izuku began panicking, looking around for a reflective surface. Itachi sat down numbly as he watched the frantic boy run around. No, that can't be happening. There was no way he could. Itachi snapped his head up and looked at Izuku again. Unless.

"It's your Primal chakra, it probably gives you control over the Sharigan," Itachi looked between the emerald colored orbs that now rested in the leather drawstring pouch and Izuku. The eyes of who should now be a vivid red. except they weren't anymore.  Instead the eyes of Shisui Uchiha,

Were emerald green.
