Alright, here's my first attempt at a vocaloid fic. It'll be a two-shot, so don't eat me alive, ok? :D

Anyway, I don't own vocaloid or other such related material. On with the show!


"Why are we here? We're not supposed to be here, Len." Rin told her twin. He had dragged her to an old factory that had been there for years. It was apparently still dangerous, so no one went there. "Yeah, I know, but I'm curious as to what's in there." Len replied.

"Someone dared you to go in and you don't want to do it alone, huh?" Rin asked and got her answer when her brother nearly shouted a bewildered 'shut up.'

"Besides, don't tell me you're at least a little curious about what's in there. How many times have we been told to stay away from here?" He asked. "That's because it's supposed to be dangerous in there. You know, rusted catwalks, old machinery, I even heard that there might be mercury leaking in there." Rin said. Unfortunately, Len had this look that said he wasn't backing down. "I just want to see what's in there. If it's as dangerous as people say it is, we'll leave immediately, OK?"

Rin ran it through her head for a minute, shook her head and sighed. "I'm going to hate myself for this, but alright." When she said that, Len got a huge grin, grabbed Rin's arm and started dragging her round the perimeter of the old factory. Len led them to a hole in the fence, which they climbed through. "So, how are we actually going to get in?" Rin asked. Len crossed his arms and closed his eyes. "Well, I tried the front door once, but that was locked. So I was thinking we-"

"Wait a minute, you mean you tried this before? Why didn't you check then?" Rin asked. Len sighed. "I couldn't get in on my own. The only way I could find is that window up there." Len pointed up to an open window. Rin couldn't help but scoff. "That shouldn't be too hard. Let me use your shoulders."

Len was a little surprised at this, but knelt down anyway. "You're getting into this. Why the sudden attitude change?"

"I might as well try and enjoy myself since I'm stuck doing this." She said and got on her brother's shoulders. "Gah, you're heavier than you look, sis." Rin groaned and stood to allow Rin access to the window. "Shut up," was her response. Len couldn't help but chuckle at that.

"So, you see anything?"

Rin was quiet.

"Rin?" he asked, and then he was surprised when Rin climbed into the window. "Rin, what are you doing!" He called after her. Rin then poked her head out and offered a hand to her brother. "You better see this for yourself. I'm not sure I'm seeing this right."

The factory that the Kagamine twins were in was shut down due to an accident about six years ago. Apparently it was still dangerous and had been warned to stay away from it. Not just the twins, but every member of the vocaloids had been warned about this place. The twins were on a catwalk that overlooked the factory. The factory itself was pretty simple, with a basic layout. There was an assembly station in the center of the first floor that started in another room and ended in a different room on the other side of the building. There were all sorts of machinery that the twins couldn't identify and there were even some leftover parts on the conveyors. But none of this is what really caught their attention.

No, that would have been the workers.

"I'm not going crazy, am I Len?" Rin asked her brother. Len was just as entranced. "If you're seeing a bunch of people standing around wearing gas masks, then I think were both going crazy." Len said.

The workers were among the strangest people the twins had seen, which was saying something considering the company they keep. All the workers, who were standing on both sides of the assembly line, were wearing a kind of orange jumpsuit that covered most of their body, which included a kind of hood that covered their heads. They also had work gloves, boots, and, most strikingly, a gas mask. Some appeared to be female, others male, all apparently in their late teens to early twenties. At the moment, none of them were doing anything. They were just standing there, staring at the ground like zombies.

"I thought this place was abandoned. What are they doing here?" Rin asked. She was quite rightly freaked out by the sight, which Len shared. Before he could answer, they heard a door open somewhere. "Oh crap, hide!" Len said in alarm. They rushed to a corner of the catwalk and hid behind some crates.

Rin risked a look at who entered, and saw another worker. He wore the same uniform as the others; jumpsuit, gas mask and all. The only differences were that his hood was down, showing his dark brown hair, and there was also red stripes on the sleeves of the jumpsuit.

"Ah shit, we're behind schedule." He said to himself and hit a button on the wall. A bell resounded throughout the room. The workers heads shot up and they assumed a working position at the stations they were attending. The conveyors started and the line started to produce whatever it did.

"Come on people, look alive!" The man shouted at the workers, his voice muffled slightly by the gas mask. He made his way up the stairs to the catwalk, shouting orders along the way.

"We got a late start today, which isn't good. Speed the line up! Remember your instructions!"

He passed by where Rin and Len were hiding. They were holding their breath, hoping he wouldn't notice them, which he didn't because he was still focused on the workers. As the man shouted orders, the twins started whispering as carefully as they dared.

"This isn't good; we need to get out of here now." Rin said. Len snuck a look at the man, still focused on the workers. Len assumed that he must be a foreman or something.

"I think we may have missed our chance. What if he sees us?" Len told his sister. Rin looked at him. "He seems distracted now, so maybe we could-"she said when the foreman started shouting again.

"Why are you slowing down so much? You're holding up the line!" He shouted at a female worker. Len saw that she did seem to be a bit slower than the others. 'This foreman needs to lighten up a bit.'

"Get your ass up here!" he shouted and pointed at another worker, "You take her place!" The two switched and the first worker made her way to the foreman. When she did, the foreman started yelling at her for slacking and other things like that. She didn't move the entire time.

"What am I going to do with you?" the foreman asked, his anger spent. The worker didn't answer. "Maybe she's breaking down?" a voice called. The twins looked at the newest arrival, a female who wore a blue uniform. The foreman sighed.

"I hope that's not it. If it is, it means that batch is junk and we would have to start over." The one in blue walked towards the two. "Well, there's only one way to be sure," she said then looked at the worker. "Take off your mask." She ordered. The worker complied, slowly lifting her hands and peeling her mask off. Len couldn't help but feel curious as to what she looked like.

The mask lifted to reveal pale, sick looking skin, thin lips, haunting dead eyes, and when the hood came off with the mask, a sight that scared the twins to death.

Teal hair.

'Miku! What's she doing here?' Len thought to himself. He tried to tell himself that he was seeing things, but he wasn't. That was definitely Miku, except she looked sick and…dead somehow. The one in blue sighed.

"Just as I thought, she's breaking down." She said. The foreman whispered a curse. "I'll get started on recycling her batch. It's going to be a long day." He said.

"Yes, it will. I'll be in my office, come to me when you're done." She said and started to walk away. "Yes, ma'am," He said and turned to Miku. "You report to the Chop Shop, understood?" She nods and walks away. The foreman scoffed and left too. When they thought he was far enough away, the twins let out the breaths they were holding.

"Okay, now I'm worried. What's Miku doing here?" Rin asked her brother. "That's not what I'm worried about. They mentioned batches and such. What did they mean by that?" Len asked crossing his arms. "That's not the only thing. Miku looked…dead. She didn't look anything like that this morning. Something must have happened to her." Len nodded as he decided on what to do. "I'm going after her."
