A/N: This is from a super excited request on Tumblr, so let's dO THIS SHIT.
I've been wanting to do this and it'll help me with more Human AU, but since this is only a work-in-progress, I might think about keeping them as they are canon. I dunno!
Enjoy.

She hid in the shadows.

In what felt like forever, Ruby Harris hid in an alleyway, hiding and feeling her heart stop every time she hears slow, heavy footsteps and low groaning coming by. She held onto her backpack of supplies and bloody ax tightly, hoping to god she won't be found. She was covered in blood, after getting through a hoard of the undead, fresh and made her smell just like them.

It was nighttime and has to rely on sound to get somewhere safer. It was a hot summer night, the moon was only a tiny sliver in the sky, and the population of the undead only grew more and more. Now, sleeping was as dangerous as being alive, smelling nice was a dead giveaway (no pun intended), rationing was priority, and trusting people is by far the hardest thing a person could do.

Ruby was in between two brick walls, basically holding her breath and waiting around for something. She looks up, a black ladder leading up to the lowest balcony, and then she jumps to it. She grabs onto the lowest rung with one hand, and her other hand places her ax into her backpack. After she secured it, she makes her way up through the stairs.

Ruby had enough muscle to do this, but she was so nervous for any scares or surprises. After reaching the balcony, she had to start going up, balcony-to-balcony, stair-to-stair. She quietly went up, not wanting her heavy steps to attract anyone, and made her way to the roof.

She reaches the top. She was sweating and out of breath as she looked down. She placed her hands on her knees as she catches her breath again. She stands up straight again, staring up at the night sky.

She always loved the stars.

The city was so dark that she saw millions of them above her. She felt a sense of relief whenever she looked up at them.

It felt like home.

The sky was a deep blue. It was practically black. But, the hint of blue was there and it made all the stars and possible far off planets pop out and be more prominent. It was a beautiful hue Ruby has never seen.

She sets her bag down and she sits down. She crossed her legs and resting on her hands. As she looked up, it was quiet. It wasn't silent. There was always surviving birds chirping and then groaning and dragging feet on the street ground.

Ruby sighs. Her heart calmed down from the risky ladder climbing she had to do on the fly. She lies down, putting her hands behind her head, and outstretched her legs.

She seemed to have fallen asleep. When she opened her eyes again, the bright sun burned through her pupils. Reacting, she shut them tightly and rubs her eyes with her fists. Sitting up slowly, she crosses her legs again.

She sighs, "Another fucking day..."

She stands up, legs slightly wobbly and weak, but she grabs her axe out and then lifts her bag onto her back.

She walks near the edge, looking down from ten stories above, seeing basically nothing in the vicinity, surprisingly. This was suspicious, but with slow steps, Ruby left down the balcony stairs.

She made it halfway, but then as she touched the fourth level, she heard something thump within the fifth story room.

Ruby turns around to the source, standing in silence as she waited for another noise to happen inside the room. Her blood ran cold and her heart skipped a beat. It could be anything inside, even just another zombie, of some poor soul that took their own life and came back.

She decided to run down, not wanting to deal with any at the moment; she did just wake up after all.

Then the room made a louder noise.

She froze for a second, but continued on her way to her next destination.

But the room kept making more noises as she left. Now it seemed whatever it is is actually trying to get her attention. As she continued further away from it, the noises became louder and rather than one thump it would be three or five of them.

Ruby, now pissed off at whatever is inside, walks back up to the window of that room. The noises then stop, making Ruby furious and felt as though she was going crazy in this already-fucked up world.

Suddenly, a hand slapped against the window, covered in blood and smearing it against the glass. This startled her and nearly fall off the balcony. Whatever this was, they were lying down on the ground and near death.

They slowly got up, revealing a girl with long and disheveled blue hair, white cloth covering her left eye and held by gauze. But the cloth had a giant red and new blood stain right in the middle. She's cut up and shaking from what she has experienced in this room.

Ruby gulped hard, her throat dry, but she placed her ax in her bag and tried to open the window.

The girl on the other side was somewhat unaware of everything around her, as her good eye was glazed and half-lidded. Maybe she was just hoping that someone would happen to be around if she continued to make noises. Ruby tried to open it with all her strength, but nothing.

The girl was looking back at her, as if she was lifeless, but her bloody hand reached up to the window sill, near where the lock is. She was sitting up and was agonizingly slow, but Ruby was patient, with a little panic in her eyes.

The girl wasn't able to unlock the window, as she continued to try, her arm was shaky and she twitched.

Ruby looked around, now seeing zombies off to her left walking through the street.

She muttered "fuck" under her breath, but Ruby looked at back at the girl.

"I'll try to find a way for you to get out." She mouthed. She left, without noticing the girl placing her hand on the window again, watching her go.

Ruby made it to the bottom, stuck in-between brick walls once more, trying to get her way around this building. Her obstacles being the zombies she sees and she doesn't see, it was going to be tricky as to how she was going to get to her.

Ruby grabbed her ax again, readying it in both hands to swing it at the zombie that is straight ahead from her. She takes a deep breath, realizing how stupid this idea was, but she ran out, swinging and penetrating through the zombie's head. It got stuck halfway, having to tug it out once the zombie hit the ground.

The blood splattered onto her face, arms, and torso. In her surroundings, she has captured groups of zombies' attention who were eating from the corpse of a horse. About fifty were around, but Ruby looked around frantically and hyperventilating. She ran into the brick building the girl is in, slamming the door and locking it.

She ran up the stairs that were next to the door and going in a spiral. Her head was thinking of so many things at once; she couldn't focus properly and wanted to just scream, but with the banging on the door, it kept her silent.

She made it to the fifth floor. The room was all the way at the end, with a dead body lying in front of it. There was a putrid smell and it nearly made Ruby throw up. She took a deep breath through her mouth, walking slowly towards the room. The corpse had a hole going through the back of their head and the blood splatter meant this person got shot as they were leaving the room.

Maybe shot by the girl?

This relieved Ruby, since a shot to the head meant it won't come back. The body shows it has been decomposing for maybe a few weeks? It had happened way before Ruby arrived to the city.

She walks over it and grabs the door knob, checking if it would open. As it should be, it was locked. There was no way the girl was going to be able to make it to the door. So, she grabbed her ax and started to hack at it.

With every grunt, she managed to cut through the other side, kicking the rest off with her boot-covered foot.

Across from the door, the girl still sat there, looking out the window.

Ruby, out of breath, walked towards her.

A/N: And yeah! That's it! Sorry for the delay, I had writer's block for A LONG TIME. But, I'll try to write regularly again!
Review and shit.
