A/N: Decided to bring this over from my account on the Archive so you lovely Readers here on FF can enjoy it \ (•◡•) /

It's a self-insert featuring the bestest Operator of all time, 6O. Since there are so few reader-inserts I decided to make this one. Please be forewarned that updating will be slow going as I'm working on several projects at once. Apologies in advance for any errors I missed.

PS: There will be some spoilers and I wrote this with the mindset that people know what the Operator Uniform looks like already. Additionally, this won't strictly follow the canon events in-game but some will be hinted at.

A long yawn escaped you as you rolled over in your bed. Somehow it had become more warm and comfortable - a fact that you weren't particularly concerned about. With great reluctance you slowly pulled the blanket to the side and sat up. As you were stretching a number of red flags began to pop up. "What the hell…" You slowly trailed off as you surveyed your surroundings. Wherever you were, it was certainly not your room. At least, you were certain that it wasn't. The room was relatively small. To your left, right next to the bed, you noticed a console of sorts. What you could only describe as a holographic screen seemed to hover over the smooth steel surface. Just above the console, you noticed a small window which allowed a small amount of starlight to filter into the room. You looked down at your feet but frowned when you noticed that your surroundings weren't the only things that changed. Your clothes had changed too. It seemed that you were wearing… some kind of uniform? A cold sensation crept across your senses. Accompanied by an odd weight on your face. You brought your gloved hands up to your face. Feeling the metal band that ran over your cheeks, under yours eyes, and up over your head. The whisper of fabric disturbed the air as you pulled off the band. Blinking one, twice, as realization dawned on you. It was a veil. Embroidered with small gold four sided diamonds. Despite the grey lighting of your room, the dull black material reminded you of satin. "Where… am I?" Your voice was quiet. Tone barely audible over the distinct, soft, hum of machinery that seemed to emanate from behind the steel walls.

A timid knock disturbed your thoughts. "O-Operator? Can… Can I come in?" You started at the voice. Head snapping up to look to your right. There was a distinct outline of a door. Almost reminiscent of a perfect square but instead with rounded edges. What should you do? What did that person mean by Operator? What was an Operator anyway? Did they mean the kind where a person works with heavy machinery? You shook your head. If you didn't say anything, who knows what might happen. You deftly slipped the veil back into place before rising to your feet. Quickly placing a hand onto the wall at the foot your bed for support. Of all the shoes to be wearing, why were you wearing high-heel boots?

"Come in" You called, lowering your hand while straightening your back. There was a pause before the door slid up into the ceiling. Most likely into a hidden compartment. A child, maybe about 15 or so, stood in the threshold. She had brown hair and wore a black jacket with gold embroidery and black shorts that stopped just below her knee's. The boots she wore shone in the grey lighting. What caught your attention wasn't the gothic style of her outfit. But the black blindfold tied about her head. The nameless visitor didn't say anything as she stepped into the room confidently. As if the blindfold wasn't even there in the first place. She looked up at you with a small smile.

"Good morning, Operator." The young girl said in a friendly tone as the door slid back down. Giving you two privacy. You weren't really sure what to say in response. This felt like some strange dream. But… somehow, it felt real. Just what is going on? "I'm Number 40, Type S – But you can call me 40S. Command informed me that I'm you're Assigned Unit." You could only nod mutely at the peculiarly named girl in front of you. 40S held a gloved hand out to you. "I'll do my best to keep up." She said while tilting her head ever so slightly to the right. The glove was made of shiny black leather. Encompassing her hand, wrist, and half of her forearm. You looked off to the right as your thoughts searched for something, anything, to say. But you found it difficult when you still couldn't wrap your head around what was going on. It was barely audible, but you heard 40S mutter something to herself before you felt her tap your forearm. "I know this is pretty disorienting since you just activated. But Command wants to see us. What with you being an Operator and all." You looked down at 40S as she spoke. Only able to muster a nod of acknowledgement again.

40S led you out of the room and into the barren hallway outside. The first thing you noticed was the odd curvature of the hallway itself. As if it was part of a large circle. You looked behind you as you walked and found that it was just like in front of you. Curved upwards as if it were a circle. Out of the corner of your eye you spotted a large window. Revealing – you somehow managed to suppress a gasp of surprise as you slowed to a stop. There was just no physical way possible for – "Is that…" You trailed off as your eyes widened. Yes, you've seen dozens of pictures taken of Earth from orbit. But they never really captured the inherent beauty of the planet. The blended colors of green, white, and blue painted on the black tapestry of space amazed you. It was beautiful.

"Pretty Impressive, yeah?" This couldn't be real. But 40S' confirmation gave you pause. Prompting an unseen hand to rest on your shoulder. "It's hard to believe that Humanity is at war just by looking at it." 40S added, capturing your attention. You looked at her but didn't seem to notice. Instead gazing at the planet while standing next to you. It was at that moment that 40S' words registered in your mind. Humanity was at war? A frown tugged at your lips. That… didn't make sense. The questions only continued to mount as 40S motioned for you to follow before continuing down the hall. Leaving you with an uneasy feeling in your chest. None of this made any sense. This had to be just a bad dream. You considered trying to pinch yourself. But you quickly dismissed the thought. The only logical thing to do right now would be to wait. 40S was taking you to see this 'Command' that spoke about earlier. Perhaps they could, at the very least, help you get your bearings.

The tell tale 'click-clack' of keyboards was the first thing you noticed when you and 40S stepped into what 40S called 'Command'. It was a massive room with a floor to ceiling monitor that dominated the other side of the room. You were speechless. Although the grey lighting made it difficult to see, you still marveled at your surroundings. There were dozens of women dressed in the same outfit you wore. Some were speaking to people who looked just like 40S while others spoke to people wearing various dress-like outfits or wearing intimidating armor that vaguely resembled Samurai armor. The one thing they all had in common was the outfits. Each one seemingly designed with the same gothic theme in mind. You noticed 40S standing on an oval platform. When you stepped on it, you heard a hiss before the platform began to descend. You grabbed onto the side while swiveling your head left then right. There were numerous platforms that seemed to be mounted on the wall before you. Each one occupied by terminals much like the one in the room you woke up in. Each one manned by someone dressed just like you. It suddenly struck you that this was what 40S meant. These women must be 'Operators'. As the elevator descended, you began to pick up on fragments of their conversations amongst themselves and the people they were talking to.

"Be sure to back up your data regularly!"

"- I swear, this is the 8th time this week-"

"-Local Resistance will meet you at-"

"Just because you're a B Model doesn't mean that-"

"You what?! How could you 'lose' you're Pod again!?"

The elevator slowed to a stop. Forcing you out of your concentration as you followed 40S. As you tried to keep up with 40S' pace, you noticed the same emblem embroidered on the half sleeve on your arm was stamped on the floor. At its very center stood a woman dressed in all white standing next to a peculiar terminal. Her piercing gaze seemed to force you to attention while 40S spoke, "You asked to speak to us, Commander?" You noticed that 40S' demeanor had changed. Almost as if a switch had been thrown. Causing her to shed her friendly demeanor. You couldn't help but feel that these people were members of some form of military. Which made sense, given that 40S claimed Humanity was at war.

"Ah, good, I'm glad to see that you've finished your activation, Number 31." Your frown from earlier returned. Number 31? Was she – "I imagine that 40S has already told you, but I have assigned her to you. As her Operator, it will be your job to ensure that she is armed with the necessary information to complete her missions." The 'Commander', as 40S called her, looked to your counterpart. Expression emotionless while she stared at the young woman. A moment passed before 40S held her left hand over her heart. Palm towards her chest. She stayed that way for just as long before she left. You watched her place her hands behind her head as she stepped onto the elevator. Casual, relaxed, demeanor back as though it had never left. "I'm assigning you to Operations Team Gladius. Number 6 will help you learn what is expected of you. Despite her… unique personality, 6O is just as capable in completing in her assignments." You looked back to the Commander who affixed you with that same piercing gaze from before. "You are dismissed. Glory to Mankind." The Commander held her hand over her chest in the same manner that 40S had.

She spoke with such finality that you had no choice but to mimic her, "G-Glory to Mankind." You turned and started to make your way to the elevator. The Commander didn't point out this '6O' to you. But you imagined that she would most likely find you. She was supposed to mentor you on your duties, right?
