Once a Shinobi, Now a Hero

Kakashi gasped as he woke up. With quickened, panic breaths he spun around rapidly, trying to see exactly where he was.

"Rin..." he muttered in realization. "Rin! Rin, where are you!" He called out getting fully to his feet. He was in some sort of alleyway, barely lit up by the falling sun. He heard no voice return his call but he found a person he recognized.

The person who killed Obito. Him. Kakashi shuttered in barely restrained anger, taking a step forward with dark eyes. He didn't realized there was a puddle under him until he stepped in it which alerted the Jounin and caused him to turn around.

The man was not smirking like he always was. He looked confused. "So, you are alive kid."

Kakashi was barely listening and broke out into a full sprint, crashing into the man's chest and sending them both tumbling out of the alleyway and onto a main road. Onlookers were surprised by the noise, but had yet to see the cause of it, only dust that already seemed to start disappearing.

"What's going on?"

"Is a hero fighting someone?"

"I didn't see a villain running through here."

It was neither a villain nor a hero that were the cause of the panic. As the smoke cleared away it was as clear as day that the cause of it was some man and child dressed in strange clothing with... swords.

The boy was atop the man, putting all his weight on the blade that the man under him was forced to block.  Kakashi was straining his muscles so hard that he was beginning to get a headache.

The Jounin grimaced hard, fighting against him and gravity and losing. It seemed he was weaker than he was beforehand. That only made the job better for Kakashi.

"A-A kid?"

"What's going on? What are they doing?"

"Someone call the police or something!"

Kakashi paid the extra noise no mind as his blade inched even closer to the Jounin. Just a bit more. A bit more until he could put this man to death.

Suddenly, something wrapped around his shoulders, arms, and abdomen and dragged him off before he could move. Someone had snuck up on him without him noticing. He craned his neck and followed the weapon to its owner. A man dressed in all black, his eyes glowing red and his hair waving in the air. Kakashi wouldn't be deterred though, he wouldn't let his target escape him while he was weak.

The scarf barely strained under the weight of his hand before lightning passed through it, going straight at the owner of the weapon. The man's eyes had widened before the lighting struck him, electrocuting him. He froze and stuttered violently as Kakashi felt the material around him slacken. Like the ninja he was he slipped through the material and hit the pavement below, focusing his aim back onto that man.

The Iwa Jounin chuckled, whipping away blood of his lips. "You really are different, brat. But let's end this." He grinned, aiming the blades tucked in his forearm at the white-haired boy.

Kakashi was more than happy to do so. He crouched low and a couple of hand seals later, lightning sparked in his hand violently. His hand spasmed, nearly unable to keep his chakra in control. His Chidori had never been this strong before.

In an instant, Kakashi was rearing his arm back as Kakkō elbows shot up to have his blades cut the smaller ninja. They had rushed at each other so quickly that the ground beneath them erupted and debris from the street shot into the air. Buildings around them could barely stand the pressure as the glass in then exploded outward at the power right before they clashed.

Suddenly, the ground shot up between them but they had already been in motion and they both struck it. Both of their chakras reacted to it, sending both of them back in a fiery explosion that rocked street they were on.

Kakashi slammed into a the side of a building. His eyes shot open and he gasped as his back flared up, but he was lucky the pain woke him up as he began to slide down the building. He looked up and gripped the hilt of his White Saber Blade before turning himself midair and striking the building with it. His descent began to slow until he came to a screeching halt 10 meters off the ground.

He breath quick breaths to both calm himself and to get air inside him, he didn't know he'd been holding it in. Immense pain suddenly shot through his head and he gripped his eye in pain as blood began to leak down his face. He grimaced hard and pulled on his blade. It came out of the building but he wasn't ready for it. The pain he was going through didn't help and he fell down onto his back.

Suddenly, he felt like he could stay awake. Darkness crawled into the corners of his vision and he felt his eyes closing. A single tear fell from his implanted eye. He didn't kill his friends' killer.

Kakashi woke up once more, but this time he heard the soft beep of a hospital machine. He was no longer filled with rage, so when his eyes scanned the area around him he saw the white, clean room that surrounded him. Then when caught the smell of strong disinfected, he knew where he was.

A hospital.

Pain shot through him as he forced himself to sit up. He pulled the IV out of him and was able to get his legs over the side of the bed just as the door opened. An old woman walked in, and Kakashi guessed she was a doctor by the way she was dressed. She must've been taking care of him.

"Stop there." She said with authority. "Back into the bed. You need to rest."

"Was there someone with me!" Kakashi asked, disregarding her order. His hand clutched the covers harshly. He didn't kill that man. He was still alive, running around.

Her brows scrunched together. "No... there was only you. Was there someone else?"

Kakashi shook his head and felt his leg shaking slightly as his covered feet touched the floor.

"Not another step." Kakashi turned to the door and saw a man he recognized as the one who tried to stop him earlier. Beside him was some sort of... block thing. Was that some sort of Jutsu.

The man walked closer to him, standing in front of the old woman. "Lay back down. You need to tell us what you were doing fighting in public and using your quirk on a pro hero."

Kakashi didn't open his mouth even though he was confused. He tried taking a discreet step back, but his injuries made that impossible. The man's gaze hardened at him and he took a step forward after Kakashi.

"Don't try it." He warned.

Kakashi let his lone open eye examine each of the adults in front of him. The man before him was skinny, but tall and he remembered more than most of how dangerous he was. The man was no doubt faster than him and even though he might've been distracted, the man snuck up on him before he could even react.

The woman thankfully didn't look much of a physical threat but the other thing looked powerful. Though slow. Maybe he could get away, but he would need some sort of distraction.

No Elemental Jutsu. His chakra was too low for that. His body was weak and his weapons had been taken off him at the moment. His eyes searched the room briefly but he found none of his weapons in sight. Damn, an old fashioned substitution would have to do.

He broke out into a run, leaping over his bed and going for the window on the other side of the room. "Hey!" The large man yelled but he wasn't fast enough.

Someone was however and that same capture material shot out and latched around his limbs just before his finger could touch the glass. He was drove down into the ground by the scarf thing.

"Aizawa, please be easy on him. His body is nowhere near healed enough to take any significant pain." The woman said.

Aizawa glared at him. "He's a troublemaker no doubt." But he was quick to be as young as he was. Aizawa had no doubt someone like him could be a hero if he didn't constantly try and defy pros.

The stone man in the back walked forward with his hands out to show he meant no harm. "Kid, listen. We don't want to-"

A crash sounded and they all jumped, turning to the now freshly broken window. Aizawa moved first, running up toward the window, but when he looked out, he saw nothing.

He gripped tightly at the window seal, nearly cutting himself on the remains of the glass. "He had a lightning quirk." He muttered.

Kakashi had ran for at least 30 minutes before his body finally made him collapsed. It was only a matter of time, he knew he was running on embers of his chakra. Barely enough to sustain the life in him. He decided not to question where he was as he ran, but his Shinobi eye had run across his surroundings on instinct and he couldn't completely ignore what he saw.

He pushed himself to his feet, stumbled and then fell against the wall, sliding down to the ground. He gripped his left, closed eye. Today had been an influx of information and confusion, and now he just wanted to rest.

His instincts as a Shinobi would've normally told him that sleeping in unfamiliar territory and not checking his surroundings was a death wish, but his exhaustion drowned out any voice it would normally have. His eyes were heavy, and his adrenaline wore off to reveal a worn body and mind. With his low chakra, there was nothing that was going to keep him awake.

Once more, darkness claimed him, and this time he gladly fell into it. He didn't know that it would be days until he woke up.

Aizawa was not in the good mood. He barely slept these past couple of days. He had spent the entire day teaching the first lessons to his newest class, and all night looking through countless avenues and patrol routes looking for the student that escaped his grasp.

The white-haired brat as he dubbed it.

The only person to escape his grasp in a long time. He'd been utterly duped by the boy and with all his experience as an underground hero, was unable to find even sightings of the brat. It was like he didn't exist in the first place. He'd run into a brick wall; a dead end. Before he could further himself into depressing thoughts, a hand smacked him on the back and sent him forward but an arm grasped around his neck to keep him up.

He turned to his left in annoyance. "Mic."

"Eraaaseeerrr!" The loudmouth teacher screeched loudly. "Why the long face? Still haven't slept a wink because of the child?"

Aizawa ignored the question, slightly sinking only his capture weapon. "He was quick. I still can't believe he got the drop on me like that." The way he did it so seamlessly was what bugged him. Moves like that shouldn't come from someone so young.

Present Mic gave him a curious look. "Was it really that bad?"

He didn't respond once more. Mic could tell what the answer was though. He frowned at it.

"You should really get some rest, Aizawa." He gestured to his own eyes. "You'll have a sack under your eyes if you aren't careful."

"I'm fine." They walked into the teacher's lounge finding Cementoss in their brewing himself a cup of coffee. He turned to them and frowned as he looked at Aizawa's face.

"You should really get some sleep, Aizawa. It is not wise to stay up all night looking for that child." Cementoss pulled the cup of fresh coffee from the machine and held it towards Aizawa. "Here, drink."

Aizawa took it with a small thanks, taking a short sip. "I should let you know this but I'll be having the police involved in this search. Cementoss, you saw it too right? He's skilled. Good at controlling his quirk and quick on his feet."

Cementoss nodded. "Yes. I don't think I've ever seen someone as young as him react to a situation so quickly. But, that's not what has me worried."

"What do you mean by that?" Present Mic asked with an eye brow raised.

Aizawa's frown deepened. "That eye; the one with the scar on it. Recovery Girl said it was fresh and deep, enough to render the eye useless. But when we looked we say a blazing red eye in its place. Unlike his other eye, which didn't follow the light from the flashlight when she checked it that red one not only moved but it looked like it moved before she even moved herself. Like it was predicting her movements."

"That can't be true," Present Mic looked unsurely at Cementoss but his frown only made it worse, "right?"

"It is." Aizawa said. He saw it for himself after all. It was unmistakable. He took another sip of coffee, feeling the warm, sweet liquid go down his throat and he gave a satisfied sigh.

"Good, huh." Cementoss asked after sipping on his own cup.

"Wakes me up a bit." He said and looked into the cup. "Still a bit too much sugar, though."

"You need the extra energy." He said, taking a seat opposite of them and setting his cup on the rather big table. "Get some sleep tonight, Eraser. If you don't I'll get Midnight to do it. She owes me a favor anyways."

Aizawa rolled his eyes. "Yea, yea. I'll get some rest."

Kakashi stirred awake once more. He took his time to look around his surroundings, his head still spinning and his body still weak. He didn't recognize it as much but his nose did. He sniffed the air, finding the atmosphere barely changed from when he fell out here. He was still in the same place.

He pushed himself to his feet, using the wall to keep himself steady, not keen on falling on his face one more time.

He wondered how long he'd been out. He already gathered he was in some sort of strange city. His nose picked up multiple scents of people, though it was drowned out by something overbearing awful in smell. He hoped he would get use to it but it kinda smelled like coal, or something. He wasn't exactly sure, it was an unfamiliar smell.

Despite his weak body and low chakra, he still at least had enough energy to jump and move around. He did just that. Looking up, he spotted several vantage points where he would be able to jump and grapple onto to reach the top of the building. He thought of his path and executed perfectly.

Now on the building, his eyes widened when he caught a breathtaking sight that he was sure he'd never would see. He didn't even know what he was really looking at. Hundreds of people walked the streets as machines wizzed past on roads. Lights shined brightly throughout the city and he could hear someone talking. Something about their special made skin product and how it would help their skin. He wasn't really listening.

Where was he?

He leapt off the building back into the alleyway. He turned out of the alleyway to take the city in on a more personal level. At this point he was just trying to gain his bearings on everything.

He'd probably been walking around for about 20 minutes at this point. Now he was sure he was lost. No matter where he went, nothing he recognized came into view and the people, some of them were just plain weird. Like they were a mix of just the most wildest things. Some had animal features on their human bodies while others had machines. Like a toaster.

Honestly it was getting too much at this point.

And Rin. He thought, with growing fear. Where was she? He hadn't seen any sign of her at all. He needed to find a way home, and quick. Reinforcements were on their way, and that meant if he was here, Rin would be by herself. There was no way she would survive on her own, that was certain and Kakashi had a promise to keep.

To keep her safe, at all cost.

Kakashi stopped walking and hung onto the wall near him like a life line, a wave a nausea passing over him. It was like he wanted to empty something already empty. His stomach felt hollow from the inside and he grabbed it when it started to growl. He smelled a whole bunch of familiar smelling foods and ingredients.

He hadn't noticed that someone was in front of them until the moonlight had ceased to come down upon him. Not expecting it, he turned quickly and took a step back. If it were an enemy, he would've been dead. But his gaze went up to a woman with what looked to be a red dress of sorts that went down the to her knees and blonde hair covered by what looked to be metal claws and a headband. A very strange look. Just like everything else in this world.

Her reptilian like, yellow eyes roamed over him, as if confirming something. Then she bent down to his level. "Are you lost?" She asked nicely, looking as concerned as one would their own child.

She tried to reach out her hand to touch his face but he flinched back out of habit, glaring at her hand. He didn't trust her, so he wasn't going to let her touch him.

She frowned at his reaction, slowly bringing her hand back. "My god. Look at you." She muttered but his ears picked it up.

"Who are you?" He demanded, internally weighing options. He soon realized he didn't have any really. While she had a bit of meat on her bones, Kakashi definitely caught on to the fact that she was very toned and look agile and strong enough to catch him in he current state.

He'd probably been out for days, but chakra had not recovered. It was probably due to his newly implanted Sharingan. Even now, with his eyes closed, it was still draining his chakra; his body not yet used to the eye fully, though it was quickly adapting.

Kakashi took a slow step back and she frowned again, a soft look forming. "I'm not going to hurt you. I-I just want to help. I'm a Pro Hero."

Kakashi was surprised to hear that word. A hero? What did she mean by that? She had the word pro in front of it as well. Was being a hero a profession here? He really wished he knew what was going on, but he hadn't much choice.

He looked at her skeptically. "I'll go with you." If she tried anything, he'd run away.

Kakkō had seen some of the strangest things since he woke up. He'd been at this place for three days, and already he was feeling a type of mental exhaustion he never thought he would be at.

Sitting atop a tall building, he chewed on a stolen burger that he managed to swipe away from someone as he ran past them. He snickered at the thought of his action. These people weren't like the people back home. Their guards were always down and left themselves open to pretty much anything. He'd already had a pretty good grip despite being here for such a short amount of time.

He'd taken someone and used his Genjutsu on them to extract information and he learn a lot. He was in a place called Masutafu, Japan. With that, he already knew that somehow he was no longer in any part of the Elemental Nations. This world was full of quirks, special superpowers that could either be used for good or bad, spawning titles Hero's, Villians, and one he'd already taken quite a liken to Vigilantes.

Most would say he would've taken to the Villians side more, but they were viewing his actions on the surface level. He was ruthless and enjoyed fighting, but that was because the Shinobi world caused for such cruelty. Without it, he wouldn't have made it to the rank of a Jounin. He was simply doing what his Village told him to do.

He swallowed the last piece of his meal and threw the wrapper off the building, standing up and stretching out.

"This League of Villians might be my best chance of getting home." He knew from the information he'd extracted that the league had a member that could teleport. He also knew that chakra augmented abilities of anyone that used it. In theory, this meant that he could power up his ability and be sent home. His Village was still in war, and they still needed him.

He grinned in excitement. While he was here he was going to have some fun. His retractable blade shot out, gleaming in the moonlight of the full moon.
