First, do no harm: A Medic-Nin's Tale

Chapter 1

"Doctor, do you think you can save him?"- the brown-haired woman asked in a desperate voice, making it obvious that she wanted encouragement and lies rather than the truth. Our hero sighed.

"Again, lady, I'm not a doctor. And your husband is going to be fine if you just let me work peacefully."- the blonde twelve year old boy replied with a somewhat fatigued look on his face. People always asked the same boring questions. When would he ever get a "Healer, could you tell me what that little tube in the middle of my friend's mutilated hand does or is?". Ok, maybe not that far.

He refocused on the matter at hand. A thirty-seven year old male with a 40 centimeter iron spike stuck in his head due to a work accident. The metal pole went through above the victim's left eye and in a horizontal line out the back. It was surprising that the man was still alive.

The trick was to pull the javelin out while healing the brain tissue, bone and any other matter that was there as the spike left. He couldn't afford to use too much chakra or the healing jutsu would heal the places where the weapon was before it was taken out, causing it to get stuck and more damage to the patient.

However, if he "underdid" it, it wouldn't heal quite enough, killing the man. Naruto smiled. Finally, his kind of challenge.

He slowly pulled the metal bar out of the civilian's skull with his right hand, repairing the damage with his left one. It glowed in green light, produced by chakra. The woman was amazed at it. Shinobi really could do fantastic things.

"So, mind helping me?"- he snapped the lady out of her trance, confusing her.- "Nothing too big, just talk to me. Helps me keep calm and concentrate. Who are you? Who is he? What's your story and how did this happen?"

At first, she was spooked, but quickly smiled, nice memories flooding her before new, fresher ones of mere minutes before came, bringing tears back to her eyes.

"I'm Haruno Kigiku, that's my husband, Haruno Saboten. He took my name after we married, since he was an orphan. We met a long time ago when he saved me from a group of thugs who were hunting for their "fun night" in the New Year celebration. He brought me a Sakura flower every day after that, telling me he wanted to win my heart. Needless to say, he did..."- she told him, adding completely useless details, betraying her calm (or trying to be) persona, showing that she was in fact absolutely scared and trying to distract herself with random gibberish from the harsh reality that was the show in front of her. She sighed.- "But things haven't gone well lately. Taxes have gone up and our daughter, Sakura, we gave her her name for obvious reasons, has gone to the Shinobi Academy. It costs us, to say the least. So my husband, determined to help his family decided to get a second job, at the nearby weapon factory. I don't know how it happened...I just... *whimper*...saw him stumble out the door with that...thing in his head and ran as fast as I could before you stopped me. You know the rest..."

"..."- Naruto didn't reply as he pulled the rest of the javelin out, quickly closing the wound and mending any torn, cut, ripped or smashed material.- "Well, Miss, no need to worry anymore. He'll be fine."

The hooded boy stood up from the now ex-patient, throwing the weapon away. He was wearing a black hoodie with "Healer Angel" written on the back and black, really baggy pants that allowed for comfortable and swift movement. Half of his face was covered, and the only features that were recognizable were his sky blue eyes and the blonde spikes of hair that could make themselves stand out. His fingers, which came out of the fingerless gloves, were covered in blood, something he didn't enjoy much, but just decide to take.

"Kigiku, what happened?"- a voice came from behind them. As they turned around they found it was a civilian, Yamanaka Yagi, Ino's mother. Unlike her husband and daughter, she had brown hair and eyes. She ran towards them before noticing the hooded person's blond hair and blue eyes. Also, one whisker that wasn't covered by the mask. The woman also noticed the bloody spike, hands and the husband of her best friend knocked down on the ground.- "K-K-Kyuubi! It's the Kyuubi brat! What have you done to Saboten? ANYONE, HELP!"

Naruto sighed as he turned around again and grabbed a small cylinder from inside one of his pockets. He snapped his fingers at the pink-haired woman, getting her attention.

"Your husband will be unconscious for at least ten hours. When he wakes up, he'll have a major migraine. Give him one of these."- he threw the pill box at her before jumping on top of a nearby house.- "Of course, have him eat something first, or that'll ruin his stomach. Remember, one in the morning, one by night."

The blond-haired boy noticed that a crowd was building some meters away. Apparently, the Yamanaka lady had convinced them that he had done something, and they were all ready to fight for his blood. He sighed once again before running away.

"NO, YOU'VE GOT IT ALL WRONG, HE DIDN'T DO ANYTHING! HE HEALED MY HUSBAND!"- Kigiku yelled at them in desperation. She didn't want the man that had saved her husband's life, herself from mental trauma and her daughter from being half orphaned to be thought of as a villain.

"Kigiku, I know he must have seemed like a hero, but he hurt your husband! Even if he didn't, how are you sure that by "healing" him he didn't just toy with his body? Hell, maybe even put a demon inside him!"- the leader of the crowd, now a man, tried to reason with her. If that's what you could call reason.

But they didn't get to do anything to the healer as he ran through the rooftops, dropping down into a dark alley several meters away. No eyes on him. Or at least, that's what he thought. A hidden camera, similar to those hidden in every nook and cranny Konoha was made of had its lense on the "Healer Angel". If you followed the wires and the connections the camera made, you'd end up in an entirely different part of the world. In another village.

Behind the computer was a red-headed girl wearing the forehead protector of Kusagakure.

She seemed frustrated, or rather, confused. What drove that blond boy to go on and help people? He was a mystery, and although she enjoyed cracking misteries, this was an uncrackable one. She had watched him several times healing people from work accidents, abuse, fights, or even self-mutilation, but the outcome was always the same. He was always chased away without so much as a thank you. And he didn't seem to care.

The kunoichi followed his movements, switching cameras as he slid through the shadows, going by civilians unnoticed. The blond was just one big puzzle that her shiny, almond-shaped glasses couldn't help her see through or solve.

That was something that both frustrated her and interested her. Hard puzzles were always the best ones.

"Karin, anything new on your target?"- her supervisor asked. She sighed as the tap of one key redirected her to the raven-haired Uchiha. He was a broody boy who enjoyed training and looking like he had had a kunai stuck up his ass by life. Not interesting at all, and a puzzle she had solved on day one.

"No, sir. But I'll stay on it."

Meanwhile

"Naruto, I see you're here. Finally. Rumors of your endeavors have already reached my office. Some about you summoning a demon and sealing it in a man's head, others about stabbing people with iron spikes... You know, the usual stuff."- the Third Hokage spoke to him as he entered the not too small, not too large workplace. He smiled. He liked speaking to the old man, since he treated him like a human being and actually thanked him for his work.- "What did you actually do? Who did you save this time?"

"Haruno Saboten, the father of this year's top Kunoichi, Haruno Sakura. Work accident, he had a spike put through his head. I cured him and removed the spike, but I don't think the villagers really saw it that way, Hokage-sama."- Naruto answered with the smile still on his face.- "Anyway, in your message via ANBU, you said you wanted me to meet someone?"

"Oh, yes. Thanks for reminding me. Boar! Get me Hatake Kakashi!"- the Hokage ordered, and in response, a shadow blurred from one edge of the office and disappeared. Minutes later, it was back, but a silver-haired ninja was also there. He had his left eye covered by a tilted forehead protector, but aside that there was nothing unusual about him.- "Naruto, I want you to meet the Jonin that's going to train you and lead your team."

Naruto nodded, examining the man. Sharingan Kakashi, the Copy Ninja. The man who copied over a thousand techniques and cut lightning in half before it reached the ground. Impressive, but still confusing.

"But I thought you wanted me to fail the Bunshin and Henge exam for the second time (I know he failed it three times, but this is a fic, mates.) so I could still spy and scout inside the Academy for you, Hokage-sama."- Naruto replied. The old man shook his head with a smile.

"No, not anymore. Pass this exam. We need to put you in a team with two problematic soon-to-be Genin."- he explained.- "It's time we reveal your genius."

"Let me guess, Haruno Sakura and Uchiha Sasuke?"- the blond asked, receiving a nod as an answer.- "I understand, but could you tell me why?"

"Sakura needs someone to bring her down to reality and scare her out of being a fangirl. She has too much potential, we don't want to waste. And Sasuke, I'm sure you know his story. We need someone we trust to keep him on the right track, even when Kakashi isn't around."- the Hokage spoke, lighting his pipe.

"So, basically you need a semi-teacher for the kunoichi and a best friend for the Uchiha. Ok, I accept the mission, but I ask one thing of you, Hiruzen-sama."- the boy said.

"What is that?"

"I don't want to reveal my true self just yet. Say, the Chuunin Exams are not too far away, how about then?"- he suggested. He wanted it to be a true surprise, impossible to forget, he wanted to show them all how they were so wrong.

"Sure."

Minutes later, the Healer boy was walking aside the silver-haired Jonin, finishing up with the mission details.

"What if even with all that, he still tries to run away?"- Naruto asked, making Kakashi stay quiet for a bit before turning back to him again.

"Well, then either I or you kill him. I'd say Sakura, but we both know that not even the mightiest of training programs could turn her into a killing machine into so little time. But eventually, she'll understand this is our way."

"Yes, even as a medic-nin, I see that every path makes a ninja kill. I learned my art in order to heal and help people, and yet my fighting style is summed up of ways to use my knowledge of the human body to quickly and effectively neutralize an enemy. I feel disgusted that I have to break my oath (Hippocratic Oath), but as you said, it's our way. Someone has to do it."

"Exactly."- Kakashi stood silent for a few minutes after that, meditating on his new information. He had always thought that the orange-wearing, blue-eyed jinchuuriki was a class clown and a prankster who had no future in the shinobi's way, but he now looked at him on a whole new level. He was high Chuunin at least just by the extension of his medical knowledge. And his spying, scouting and assassination training took him to mid-Jonin, at least in his opinion.

"Ok, Kakashi-senpai, I'll make sure to think over this conversation later and see what data I can get from it. Don't forget our Raiton training tomorrow. Now, I've got an exam to pass. See you soon."- with that, he vanished in a swirl of leaves, surely to change back into his orange clothes and dumber personality.

Later

"NARUTO, WHY ARE YOU ALWAYS LATE? GET YOUR ASS DOWN HERE!"- Iruka yelled at him as soon as he entered the door. So much for a calm and civilized exam. Being my disguise-persona hurts my ears. Mental Note: Reconsider only revealing myself in the Chuunin Exams.

"Sorry, Iruka-sensei. Had to finish the twenty-sixth bowl of ramen! Can't waste!"- he quickly made his way down the stairs of the classroom and placed himself in front of the student line that stood by Iruka.

"I don't know why you even bothered to come, we all know you're going to fail it again."- Kiba mocked him with a smirk. Mental Note Number Two: Remember to kick this guy's posterior as soon as I get the chance.

"SHUT UP! I CAN DO IT NOW!"- he replied, trying to make himself look as dumb and childish as possible.

"Gah, whatever! Just stand in front of me, create two clones and transform them plus you into me. You got that?"- the Chuunin teacher ordered. He nodded and concentrated. Not that he needed to, but he had to put up a show.

"Iruka-sensei, I don't think he got that. I think you'll have to draw him a map or something, because he looks like he doesn't know what he's about to do."- Sakura joined in, getting a couple of laughs from the student line and glancing at Sasuke to see if he had laughed. He hadn't.

"Look, dobe, just go on and fail and get it over with, I'm sick of waiting. I could use this time to train."- the raven-haired Genin told him, making the class laugh more. Sheesh, I can't believe I used to like Sakura. Looks like it's going to be a long time until the Chuunin Exams start.

"Kage Bunshin no jutsu!"- Naruto proclaimed as he performed a cross with the half ram hand seals. Four clones promptly appeared by him, two on each side. It caught the other students unprepared, surprising them. As a spy, I shouldn't let pride overwhelm me, but I think I can get away with this little one.- "Henge no jutsu!"

The four clones, followed by Naruto, all turned into picture perfect copies of Umino Iruka, smiling back at the original. Iruka was astounded, but also happy, while the others were just muttering about him cheating in some way.

"Here you go, Naruto. Your very own forehead protector!"- the Chuunin smiled, handing the piece of cloth and metal over. Naruto put on his dumbass face and quickly tied it around his forehead, keeping his hair up. (Original much, huh?)

"Nice. Now that I've got my Hitai-ite (forehead protector), nothing can stop me in my way to become Hokage! Dattebayo!"- and with that, he left. He had too much to do, and staying around wouldn't help in the least.

He quickly made his way through the rooftops, heading for his house. He used the seal key to open the door and noticed that the living being he had had in the little cage by a corner was no more. Naruto reached for a tape recorder and pressed a button.

"Medical/Scientifical report number one hundred and forty nine. Whiskers, the little mouse I acquired from the pet shop two weeks ago has perished, showing that the antidote for Sasori of the Red Sand's poison I prepared is a failure. I shall now attempt my revival jutsu to bring him back from the dead and test my second antidote on him. I'd ask whoever is listening to this record to wish me luck, but I'm pretty sure it has no effect on the outcome."

He placed the tape recorder by the side of the cage and reached for the still non-decaying corpse that used to be Whisker's body, placing him on a table and readying himself.

He had been working on that jutsu for a long time now. He intended for it to be the ultimate revival technique, one that had no real setback. Needless to say, after twenty six mice, it wasn't working.

He did find out it made for a great weapon. Being a Raiton jutsu, he wanted it to cause the heart to spring back up to life, but it worked well into doing the opposite. However, he was sure that if he got the voltage right, he'd be able to make it happen.

The blond doctor held his hands out, looking as if he was holding defibrillator paddles before lowering them down, touching the mice's chest with both his thumbs.

"Raiton: Countershock. (One Piece Reference)"- a loud zap was heard. The trick was that the technique only sent one, quick burst of electricity instead of a continuous stream, like the Raikiri, for example.

He sighed.

"Medical/Scientifical report number hone hundred and forty nine part two. The jutsu still proves to be effective in destroying any way of life instead of creating it. As I used it on Whiskers' body, it exploded, covering me in blood and entrails. I shall clean down my laboratory and head for the pet shop to buy a new mouse in order to replace Whiskers before trying a second antidote, and if it fails, to try the jutsu with a new voltage setting. End of recording."
