Prologue

Several hundred years ago, humans were nearly exterminated by Titans, beasts that are typically several stories tall. They have no intelligence, and devour human beings for only pleasure, rather than as a food source. A small percent of humanity prevailed by walling themselves in a city protected by three towering walls: Wall Maria being the outermost, Wall Rose, then Wall Sina being the innermost. After 100 years, no one had seen another titan. But another, massive titan appears, named the Colossal Titan, and breaches Wall Maria, allowing smaller Titans to enter. Chaos wrecks humanity, especially for one girl. Eun experienced all of the horror in Wall Maria, transforming her personality, her way of seeing the world.

"The one goal I have... The only reason I lived... Is to kill every last Titan living!"

Blood.

There was so much blood.

Streaked over everything; the cobblestones, the buildings, everything.

I couldn't stop running, I just couldn't. I didn't bother looking for the bloody faces of the people I once knew.

After all, dead was dead.

There was nothing you can do to change it.

I sped forwards, my eyes trained on the point ahead of me.

The boats.

The key to my safety... My survival.

I can't die here.

The thought drove me forwards, my ragged gasps reaching my ears. 100 meters. I can make it, before the boat goes too far.

I have to!

A familiar sight crosses my eyes. A flash of dark hair, the almond shaped eyes that resembles my own. I cry out in desperation.

"Mikasa!"

Both Mikasa and Eren heard me, and turns, her eyes wide with shock, his eyes full of relief. Screaming my name as a reply, Mikasa outstretches a hand, beckoning me to hurry. I do, applying more and more speed until the wind cuts painfully into my skin.

Reaching the port, I roughly shove aside the guards that are trying to stop me, and launch myself into the air. I feel a slight yank gripping onto my boot, and I know that a guard had caught me.

It's all over.

Just before I start to plummet into the water, I feel a hand grasp onto my own, and yank me onto the boat.

I crash onto the wooden floor, all my agility and grace forgotten. Mikasa's face enters my line of vision, her dark eyes full of worry. I manage a small smile at the sight of her. She's the only true family I have, along with...

"Eun, where's Kai?" My heart sinks at his name, and my eyes sting with unshed tears. Mikasa's eyes widen. Eren crouches down next to Mikasa, looking at me with worry as Armin appears besides me, his blue eyes wide.

My brother.

My only family, after our parents were murdered.

I draw in a shuddering breath as I pull my coat tighter around me.

"He was eaten."

Mikasa tightens her grasp on my hand, her expression a mixture of sorrow and anger. Armin's blue eyes fill with sympathy, while Eren's floods with pain.

"I'm sorry, Eun." Armin says quietly. I shake my head, furiously blinking away tears.

"I'm going to avenge Kai." I whisper, my voice rising.

I'll show those titans that humanity can fight back!

How was it? Yes? No? Maybe so? Lol please review for future chapters!

P.S. In this story, Levi is younger, around 17, and the OC is 15 ^_^ I hope it doesn't cause any confusion~!
