A/N: This is my second try on self-insert fanfiction, I have this idea for quite a while and yeah...I want to try writing it!

Disclaimer: Naruto is not mine, I only used it as a base and add it with my imagination. OC is mine.

My lovely Beta: AaCcEeYy (...finally! I am so happy. I going to cry, Wahhh!)

Summary: War can bring many things. Conflict, competition and death. It's get worst if you fall in to the world of shinobi with body of five year old! With no way of returning, no hope and no home, will you be able to survive?

-"This is not a game, but survival!"-

SNAP!

Her bare foot lands on the forest floor, causing the dry branch to snap and prick through her foot, making it bleed. However, the owner doesn't have time to feel the pain. Her breathing quickens to a shallow pant as she runs through the deep forest.

Her short body is out of breath, her lungs are sore, but she continues.

She is running for her life.

Her foot finally reaches its limit as it stumbles on a nearby tree's root.

"Argh!" the brunette exclaims as her face slams to the ground. The pain shoots out like a sharp knife, and she lets out a hiss as she attempts to stand up again.

I can't stop here! Not now!

Her cheek throbs, and the sight of the thick, red liquid dripping from her face onto the ground makes her gasp. Her hand almost instinctively comes up to check. She winces from the pain and withdraws it, seeing her fingers coated in blood, the culprit a deadly-sharp stone at her feet.

"...Fuck," she curses, holding her hand to her wounded cheek as she begins to run again.

Someone—anybody! Please help me!

"Find that girl! She must be here somewhere!" The sound makes her heart leap out of her chest. She breaks into a cold sweat.

No... no... NO!

The voice is close, too close for comfort. She needs a place to hide, and quickly.

Without much thought, she lunges towards the bush and crawls behind a tree, covering herself with the foliage. Her body shivers violently from fear as the sound of rustling leaves comes closer and closer.

Thump!

Three men leap out of the branches, landing in the area she herself had just previously stood. She covers her mouth to hold her breath, staying as still as possible, but her heart is pounding so loudly she fears they might hear it. Peaking nervously through a crack in her hideout, she cranes her neck for a better view.

The three men dress in an oddly similar fashion, each wearing a deep, thigh-length, open-necked coat paired with dark-colored trousers— a style that wouldn't necessarily be considered "modern." Their clothes are all similarly adorned with the same fan-like symbol, red on the top and white on the bottom.

It is strangely familiar, yet she can't seem to remember.

Who are they?

"That brat must be around here somewhere" One man, seemingly the leader of the group, crouches down and uses his finger to touch the blood on the stone she fell over. "The blood is still fresh. She's not far."

"But we can't go on anymore..." The man with longer hair says as he looks ahead. His eyes are wary. "We have almost reached the border. If we go on, we may be ambushed by the Senju, and that will put us at the disadvantage."

Sen...ju?

"We Uchiha, will need to complete the mission," the leader says, frowning as he stands up. "That scroll we need to retrieve is what we stole from the Senju clan. It's contain a medical ninjutsu capable of saving many lives. We can't lose it to some brat!"

U...chiha?

"We need to report back to Tajima-sama," the third man says.

The other two glare and click their tongues in annoyance. The girl, still hiding in the bush, listens to the fading sound of rustling leaves as they depart. She tries to contain her pounding heart. Her little head pounds as it attempts to process what she had just overheard.

That strange symbol... Senju? Uchiha?

Then, suddenly, everything clicked. Her face paints itself with horror.

She is...

...in NARUTO?!
