A/N: So this is a new story. I got the idea, and I'd like to see how well it's received.

Check out my other Kakashi/Sakura story, Tabu Sensei. It's doing well.

I don't own Naruto.

I have no beta.

Enjoy!

Sakura looked at her reflection in the river. She had reverted back to her nine year old self. Her clothes had shrunk to fit her tiny stature and she felt ridiculous. She was a midget all geared up for battle. Her huge forehead was even more noticeable with the Reserve Seal's purple rhombus in the middle. Like a beacon. Damn! She had forgotten how big her forehead was when she was younger. Not fair!

She was a midget with a huge forehead that was decked out in ninja gear and ready for battle. Nothing threatening there. Nothing at all. She looked like a joke.

Sakura sighed. Her plan, was to travel to the past, and completely rewrite history. Make sure that Obito didn't get crushed on that mission and end up becoming Tobi. Make sure that he never came into contact with Madara. Make sure the Kyuubi was never released on Konoha and the Uchiha clan wouldn't be slaughtered. The Sandaime wouldn't die by Orochimaru's hand. All the pain that Naruto went through during his life, would never happen. Kakashi wouldn't die. She'd stop it all.

How the hell she had managed to change back into her nine year old self was a mystery. Though it was unplanned, maybe she could use it to her advantage. All she needed was an alibi. And a damn good one.

Her senses picked up an enemy and she whirled around to catch the kunai that had been aimed for her neck. She stood quickly and got into a fighting stance. The ninja who had made the attack stepped from the trees. He was an Iwa ninja, if she read his headband correctly.

"Aw how cute! Konoha sent a little girl after me! Or are you just playing ninja little girl?" the ninja taunted with a laugh.

Sakura twitched in annoyance. She hated being called 'little girl'! When she had fought Sasori, and he kept calling her that, she wanted to beat the ever loving shit out of the puppet master. Now this prick was doing it. She'd kick his ass!

Sakura glared at him and moved.

The ninja didn't have time to be shocked as her fist slammed into the back of his head. She could hear his neck snap under the force of the blow as his body made a large crater in the earth. She smirked when he didn't move, "I'm a Jonin you asshole."

"Pretty good brat."

Sakura froze and spun around. That voice. Of that person!

She laid eyes on the person she admired the most. Her shishou. Except, she was younger. A lot younger!

Tsunade was watching her with a calculating gaze. She didn't move to attack, she was analyzing Sakura. Something she always did with people she didn't know. And after seeing a little kid kill a possible Jonin rank shinobi with one punch, she wasn't dumb enough to underestimate her opponent.

"Care to explain how you're a Konoha Jonin, yet I've never heard of you? I'm quite sure that the information of a pink haired brat becoming a Jonin would've spread quickly?" Tsunade asked.

Sakura frowned. She had a job to do. She knew for a fact that her shishou was probably the most trust worthy person she knew. With her help, Sakura could possibly get into Konoha, and start her plan. Should she tell the blonde woman?

"It's hard to believe Lady Tsunade," the pinkette said softly.

The woman scoffed, "Try me."

"I'm from the future."

Tsunade blinked. Sakura blinked back.

"Prove it!" the busty blonde challenged.

Sakura got down on one knee, "I am Sakura Haruno, Jonin of Konohagakure, assistant and second apprentice to the Godaime Hokage, Tsunade Senju. After the Fourth Great Shinobi War, there was too much chaos. Nearly everyone I knew and was friends with was dead. I couldn't handle the way everything turned out. Even though we won, it was at a great price. I created a jutsu, that mixed the Hiraishin and the Summoning Technique to send myself into the past. I plan to change everything. But somehow, my jutsu had a glitch somewhere and I'm nine again, when in all actuality, I'm seventeen."

Tsunade's face didn't betray her emotions. Nothing could be derived from her blank expression.

"If you can give me a few examples, that prove I taught you, I'll hear everything you have to say. I may even help you out."

Sakura smirked. She knew everything about her shishou. "You suck at gambling. When you actually win, it's considered a bad omen."

Tsunade glared, but didn't deny, because it was a fact.

Sakura pointed to her forehead, "You created the Reserve Seal, which I was able to master during the war. You modeled it after the decoration on your grandmothers forehead."

Sakura thought about what else she had learned while under Tsunade's tutelage.

"Your grandfather, Hashirama Senju, believed strongly in the Will of Fire. You base the fundamentals of medical law on that. Rule 1. A medic ninja will not stop trying to heal a member until that ninja's dying breath. Rule 2. A medic ninja shall never go to the front line. And Rule 3. A medic ninja should always be the last of their platoon to die. That's what you teach," Sakura quoted.

"That's a pretty well known fact kid. You'll need something better," Tsunade said, taking as tep in her direction.

"Three isn't good enough, then lets go with four. Rule 4. A medic ninja who has mastered the Ninja Art: Mitotic Regeneration, may break the first three rules."

Tsunade froze.

"And if four doesn't work, then five will give you a real kick. Rule 5. Because you are the only medic able to achieve number four, you are the only medic allowed to do battle. However, since I can do it too, number five pertains to me as well."

Tsunade pursed her lips. The girl had given some good information. Not everyone knew that she was a bad gambler. And she didn't teach anyone else the Reserve Seal. The kid knew about the extra laws, while she obviously had the seal on her large forehead. She had also laid a ninja out in one punch that was barely charged with chakra.

Tsunade gave a nod. The kid was legit.

"Alright brat, why did you time travel? And don't leave anything out."

Sakura told the Slug Sannin everything! It was okay to relay it all, since she about to change everything anyway.

Tsunade was shocked speechless. So many things had happened. And she had become Hokage?! What kind of future was it? They had actually made her the leader of the village? Orochimaru turned out to be bad? The Uchiha clan was massacred?

She took a deep breath and let it all sink in. Then she turned to her, apprentice.

"Here's what going down brat. You're a war orphan that I came across during my travels from one destination to another. You were being attacked by Iwa ninja and I saw you defeat them. Your chakra control intrigued me, so I decided to teach you what I know and you learned everything within a couple months as you followed me around. This story will get you in without a problem because of my high standing in the village. I'll adopt you and you'll take the exam for Genin placement. Only the Hokage can know the real story. To everyone else, you're a prodigy that was trained by me personally. Got it? Don't embarrass the Senju name brat," Tsunade said in a strict voice.

Sakura gaped. Her shishou was officially the best person ever! Forget Power and Porn. She got the best Sannin as a teacher and she wouldn't switch, even if she was given the chance. One that taught her Principles, which far outweighed power and porn. One who cared that much.

"Thank you shishou," she said with a bow.

"Good. Now, tell me everything about yourself. I'd like to get to know my new daughter."

Sakura smiled.

A/N: End of the first chapter.

How was it?

Let me know.

Ja ne! :D
