So uhm...hey there. Ds here. I've been reading Nier Automata fics and crossovers the last week or two, and to say my thirst wasn't quenched is an understatement. I WANT MORE! But it's clear that there aren't many Nier fanfiction around, so I ended up writing my own. So...yeah. Here I am, with a story to post and hopefully, the will to continue.

I am very interested in the whole "Suddenly a living human appears" kind of fic, but the plot always gets dull. Yes, cryo freeze, yes dimensional/time travel, yes random OCs that all sound the same. I get it, classic writing, decent, but not very creative, is it?

It should be noted that this MIGHT count as a crossover, but I used my OC, and the other universe is only mentioned in indirect reference, so eventually I decided this should go in NieR section. Kudos to you if you figured out what other universe I took inspiration from.

With that, it's time to get in to the story! Enjoy the story, and fav and follow if you liked it. I'll also be answering to reviews as I love to interact and gain more ideas for what I should write on, so don't hesitate!

Well, let's get into it.

For A2, her days were simple.

She wanders around, searching for machines to kill. Things to fight. Something that would end her. Something that would reunite her with those she have lost. She kept herself together through the constant parts and gear taken from YoRHa units sent to kill her, and proceeds to use their tech to smash apart any machine lifeform she sees. Doesn't matter if it's Goliaths or a Stubby, if her swords can hack it apart, she'll do it.

But even if she's an android, she was still created in the image of humans. That means she possesses human traits. That includes curiosity, and a sense of adventure. Clearly much more toned down than the 9S models, but it exists. Sometimes she wonders, what the humans were like. How they lived, what separates them from AI such as herself. Androids are stronger, with intelligent AI that process information faster. So, what is it about humans that androids lacked? What drove humans to such heights?

A2 rarely dwells on those subjects. To her, they are merely things to wonder in place of those heavy memories she bears. Distractions at best, pointless at worst. She an Assault model, not a Scanner.

But as she stood before the ruins of an Old World Facility, A2 can't help but to investigate.

She's very deep into the Forest, and far, far from any settlements. Even the machine lifeforms are not here. There are no signs, nothing that indicated what this place might be from the outside. What A2 did noticed however, is the 30cm reinforced steel gate, still standing even after thousands of years. Rusted, but still standing. Humans made this to last.

Running her hands along the heavy steel gate, A2 looked for a way to open it. The guard post next to it has all but deteriorated into ruins, vegetation taking back the land. The door's buried underneath the accumulated soil.

"Maybe there's a way around it."-The Assault class android murmured.

She wonders, whether this gate was made to keep something out…

…Or to keep something in.

Regardless, the ruins was buried underneath a few meters of soil, but that also means she can look for an entrance from the top.

It doesn't look like the buildings she saw in the City Ruins, or the "apartments" in the Desert, not a factory, or those tall "skyscraper" in the distance of the Flooded City. It looked like a facility of sort. Maybe humans did research here.

Finding a way around the thick steel gate was more than easy, if anything A2 just searched for a spot she could jump over. The facility was in ruins, certain parts collapsed entirely, so finding a hole through the ceiling was easy enough.

"Some sort of…office?"-A2 noted as she jumped down. There were neatly lined desks, rusted and broken, the documents scattered on the floor either has deteriorated into dust, or almost…seeped into the ground where they fell. Nothing she can read.

So far, it looks like somewhere she could set up base and hide when she needs to be alone.

Turning around, A2 noticed a sign on the wall, rusted and missing letters.

"_ C _ Fo_nd_t_ _ n"

"Foundation?"-The Android guessed, not that she particularly cared.

There was a steel door to the left side of where was at. Unlike doors that she have seen in Old World ruins, this door doesn't have a doorknob. There was a panel, A2 presumed for a password or keycard. But it's rusted, the glass has broken, and A2 herself could pry this open with enough force anyway.

So she did that, using the Type-40 large blade to break and pry open the door, making a loud noise as the door breaks off and fell into the ground.

Several doors broken later, A2 stumbled across another area. It looked like a check point of sort. The doors are airtight with the exception of one, broken and collapsed on the ground, and the sign above reads "_eav_ Con_ainme_t"

"Contain? Whatever they tried to contain…don't think it worked."-A2 said to herself as she pursed her lips.

The structure changes drastically as she walked through the checkpoint. It is now heavy reinforced steel for walls and occasional broken catwalks.

There are holes in the ceiling that was shedding some light down, which was unnatural. A2 figured there could have been bombardments done here. It's been 14 goddamn Machine Wars already, it's not surprising to think nor worth the focus on. It's just ruins.

Hopping over a section of broken catwalk that led to another door, A2 was reminded of her android body, as the catwalk let out a loud noise as it bends and screeches at her weight. It's lucky that the thing didn't break off entirely.

Opening the door, A2 was met with…a bunch of yellow-ish concrete, broken off. It seemed like it used to be something, but she didn't pay too much heed.

The next 15 minutes, A2 walked around, finding that most of the doors already opened, proving that perhaps whatever the humans tried to contain here, it's probably not here anymore. Even heavy vault doors opened, the contents gone. There are unusual materials, objects and…containment procedures across the rooms. There were also...signs of WCS, blocks of salt that eerily resembles humans in distress, hands reaching out at her, at the door, in agony. She shook it from her mind and kept moving. Eventually, A2 found one door that wasn't opened.

The Android couldn't shake this feeling of nervousness as she approached the door. She's not sure what's behind the door, but it's pretty clear that her creators didn't like to let it out. It's a bit of an irrational fear, something A2 doesn't feel often, bashing through Machines and YoRHa E-types for a life.

Whatever's behind that door, it is dead already. It's been at least 8000 years. Nothing organic survives for 8000 years.

The logic was sound, and A2 then calmly opens the door. But she didn't break it open, this time, prying it open using her Type-40 sword to make a gap, then slide it open with her bare android hands.

It still took a lot of effort, but mostly just due to rust.

Infront of her, a surreal sight.

A very basic and empty room, a hole on the ceiling shining light down inside. There was a table, rust claiming it, two chairs on both sides, one fallen over, one still standing. A pile of rubble from where the ceiling caved in was in the corner of the room.

But that was secondary. Her eyes barely registered all those.

Behind the table, at the wall opposite of the door, a figure. A human figure, sitting with his back against the wall, face slumped forward. He? He. Was well dressed, at least A2 assumes so by Old World standard. He was wearing a dark coat of sort, that's all she is able to discern. Maybe something called a "suit" underneath.

The only suits she knew were combat suits.

But A2 felt like she seen something straight out of Android horror stories. Not the suit, well…the suit is a part of it. It's been 8000 years at the very least! An organic body would have decomposed by now, the clothes rot into nothingness and even the bones would have a hard time not collapsing into a pile of dust. This body…it's…pristine. Like this person died within today.

"Is it an android?"

It's likely. Maybe an android that wandered here. Doesn't look like a Resistance android though.

A2 cautiously approaches the slumped figure, her high heels clacking slightly. She almost want to point her sword at it, but something stopped her. A compelling force in her mind is in conflict with strange warning signs that A2 never received before.

There's something eerie about this situation. The Assault class noticed the ground had indentations on the dust and dirt. Shoe prints. Recent.

What happened next almost made A2 bust out B-mode.

The figure moved.

The guy MOVED!

It was a tiny jerk of the body, a small cough.

He took in a breath, clearing his throat, before looking up.

A2's not entirely sure if it's her hard-wired programming to adore and protect humans, but she's rather sure the feeling she just felt was…attraction.

He had short, dirty blonde hair, his features were young yet…firm, experienced, a neutral expression adorned his face, one that soon gave way to a look of very minor shock and confusion. His purple colored eyes stared into her sky blue ones, before from his mouth came a word.

"Beautiful."

A2 recognized that as English. Many Old World languages have been lost to time, but English at least still remained. It's one of the few main languages androids are programmed with by default. The compliment was received, but the Assault model still had hand on her sword.

His voice, his features. They reminded A2 of a prince, not that she was familiar with the concept itself, but he's clearly handsome, and his voice has this…firm tone to it. Not like a military officer, but…very close. A2 couldn't exactly get her head around it.

There are bigger concerns, after all.

"Who are you?"-That voice again. Even when he's in awe, he still managed to sound firm. Now he's just speaking normally, and that firmness doubled. His eyes are now focused and sharp.

"…"

"Been a while since I've seen a sword."-His voice faltered just a bit. Sounds like a dry throat.

"…"-A2 still wasn't sure where to start, so she does the classic A2 silence.

"I don't mind you staring, you are very pretty, but I'm sure you have more to do than just that."

"…Hold on…are you an android?"

"Android? They make those now?"-That was more than telling.

"What…"

"Now that I had a good look at you…"-He was about to get up.

A2 immediately responded, drawing her sword and pointing it inches from the...guy's face.

"Uhm…"

"Who…no, WHAT the HELL are you?"-A2 demanded.

"What year is this?"-He asked, calm but a bit uncertain.

"Answer my question first!"

"It's a complicated answer, of which I don't really want to say. Just, tell me, what year is this?"

"Answer. The. Question."

"Or?"-He challenged.

"…"-A2 was taken aback slightly. If he's organic, and...has similar appearance to androids, that means…

During that short second pause, the man already got to his feet. He's taller than her by maybe…10 centimeters? A bit more than that.

The Assault class tighten her sword grip as she pointed it at him again.

"Are you…human?"

"…Not exactly."-He took one small step forward.

A2 backed up a step, sword still pointing at him, this strange feeling of fear in her consciousness data.

He notices this, and took one big step forward, grabbing her Type 40 sword by the blade, before…

Walking straight into it.

The sharp blade went through him easily, protruding out his back, blood coating the blade.

A2 was too shocked to even process out words.

Yet, the man did not show any signs of pain, at most he stiffened his expression just a bit, as if holding his breath, as he gently guided the rest of A2's blade through his torso as he stepped closer to the android, until eventually reaching the handle, their eyes still glued to each other. She can agonizingly feel the different body structure, unlike androids. He's clearly human.

Yet…no human could survive such a wound. Even androids won't most of the time. The entire situation just make A2's processor flaring with errors.

What had she uncovered? Humans were often fascinated with fictions about awakening ancient gods. Had she done the android equivalent?

Now they are stuck in this eye contact that is unexpectedly mesmerizing and…unbeknownst to A2, many would say romantic. Although, if the camera were to zoom down a bit, that perception would change immediately.

With a slight touch of their hands, the white haired android let go of the sword, taking another step back, finding the table and lightly leaned on it, her eyes wide in shock as she looked at the figure, a sword impaled through him, yet standing calmly as if it's a minor inconvenience.

After a few seconds, he approached her again, his eyes squinted just a bit, to look at her better, now that they are under the light that was shining through from the hole in the ceiling.

His eyes then widened slightly, looking up to her face.

"What year is it?"

"It's…11945."-A2 answered, her processes still slow from the shock. At least she didn't let her jaw drop, and still maintained a relatively calm face.

"I see. I…have been out of it for quite some time."

"What…are you?"

"…Not exactly human. Born as one, but…not anymore."-He gave a distant smile before slowly removing the sword out of his body. He winced and hissed lightly, but that's about all he showed. He sounded like he got cut by something small, not impaled through by YoRHa's latest model.-"You…aren't human too, right?"

"No, I'm…an android. There are no humans left on Earth."

Now there's an awkward silence. Great.

The man offered her sword back, which she did took hold of again.

"I see."-He nodded, strangely okay with the idea.-"Explains all the peace and quiet."

"..."

"Fascinating. An Android, you say?"-He stared at her, eyeing her form up and down.-"You look stunning."

A2 scoffed, her fiery personality abandoned that slight fear in her system in favor of retorting to the compliment.

"I'm not the most well maintained android, and stop looking at me like that. It's annoying."

"...Very human-like response as well. Emotions clearly conveyed."

"What did I just say?"-A2 grounded out.

"Sorry, I didn't mean to annoy you."-He raised his gloved hand apologetically, flashing a smile.-"It's just...very fascinating. Last I checked, AI and robots were still in development. Although...I have met one such AI. It was rather unnerving back then. Strange..."

The white haired Android pursed her lips. This wasn't how she thought this ruin dive would be.

"You...are alone?"-He asked next, looking around. He must have noticed she haven't tried to contact anyone, so there couldn't be more here.

"So? What if I am?"

"Nothing, just asking. I see. Where will you go now?"

"Don't know, don't care."

"Then is it okay if I follow you?"

"Not happening. You are not following me. I'm not some caretaker."

"And I'm not a baby."-He spoke back, shrugging.-"How about this. I will only speak if spoken to, and will keep up without complaints and questions."

"No."

"...I see."-He sighed, sitting down on the chair, leaning on the table slightly.-"I'll be fine here. You go on ahead."

"...What will you be doing?"

"Nothing. I'll sit here for another couple thousand years I suppose."

"...Why? The door's right there."-She tried to use a sassy tone, but it came out as concerning instead.

"I don't know. Doesn't sound like I'm needed, so I'll just be here."

A2 scoffed, again. Isn't needed? If only he knew how important a living human being is.

"Fine. Just...stay out of my way."-All androids are hard programmed to protect humans. A2 never really tried to fight that programming, she just knew it was all pointless, a meaningless code written into them by their long gone creators.

So, when presented with a human, it is natural for her to feel a strong desire to help. And...the thought of being able to speak to a human, interact with them, she's sure many androids dreamed for this. This guy maybe a tad bit annoying, but even though A2 prefers to be alone, brooding her thoughts, the idea of a companion doesn't necessarily sound too bad. And he promises to get out of her way. That's enough for her.

"Oh?"

"And stop looking at me like that."-Like what? He's just staring. Not an intense gaze by any stretch, but...examining.

"I'm sorry. You...remind me of someone."-He smiled thinly-"I understand. I won't hold you back from doing whatever it is you do. I...simply wish to observe the world."

"..."-A2 nodded, her taciturn look recovered-"If you fall behind, I won't wait."

"Mn."-The man nodded, and followed the white haired android out.
