My very first fanfiction to be posted. A huge shoutout to Omega E The Reader for giving me countless advice and filling out many holes in my incomplete premise. This fic would've never been published without you. Thank you for everything.

Prologue

It is very dark here. Hardly anything can be seen.

In the middle of a room with not a single light on is a heavy operating table with all sorts of machinery under it. Though most of the machines appear to lack any power. Around the room are other machines of all sorts including computers but they, too, lack any power.

On the operating table is what appears to be a young girl. She has blue hair that goes just above her shoulders. While blue hair may be unusual to some, the bat wings are most definitely unusual to pretty much anyone. If one was to take a close look at her mouth, they would see a pair of fangs protruding out of her closed mouth. No doubt about it, this girl is a vampire.

Her name is Remilia Scarlet. And she appears to be sleeping on the table. Table she seems to have been strapped onto. With many wires and small pipes inserted in her skin, but none of them seem to be doing anything at the moment. No wire has any power and no small pipe seem to have any liquid going through them.

But she appears to be waking up from her slumber. Her eyes open to the darkness, her mouth opens in a yawn and she slowly makes an attempt to get up. Only to be met with resistance from her binding. Resistance that proves to not be enough to restrain someone with the strength of a vampire, though. So she resumes her "getting up" routine, removing the wires and small pipes. And no worries about wounds from ripping off those devices, vampires are quick to heal from even worse wounds. This is nothing.

And what about the darkness? Well vampires can see in the dark just fine. They're nocturnal, after all.

And that's when she realizes that she isn't in her room, in fact, she isn't anywhere inside the her residence known as the Scarlet Devil Mansion. And she has no idea nor remembers why.

"What the... Is this another one of Yukari's pranks? I won't laugh until you bring me back to my room, Yukari." Remilia says in an annoyed tone.

That's when she notices the only door in the room. She goes to it, only to realize it's one of those hi-tech doors she heard of. And it only opens from the outside, it seems, as she can't find anything that could open the door neither on it nor next to it.

But that door is no match to a vampire's strength, she just forces the door open with little to no effort.

Once outside, the young vampire is surprised that the lights are on. "So it's only this room that lacks any power, it seems." She says while pondering the situation. She is currently in what appears to be a computer room. She hasn't seen many computers, but she can recognize a computer when she sees one. Although, she's never seen computers this advanced before. So there's no way she's still in Gensokyo.

There are only two options in her mind: Either she's in the Outside World, or this is the Lunar Capital. Neither of these options are to her liking.

She notices that the room is oddly chilly, despite being indoors. Granted, as a vampire, this is nothing, but the way it's chilly across her entire body is unusual.

It truly is odd that she'd feel such a chill even through her dress, she wonders if there's a hole in it or some-

That's when she noticed something she feels stupid for not noticing sooner: She HAS no dress.

She's completely naked. No socks, no underwear and even no hat.

Her face turns red as a tomato from both the embarrassment of being naked like that and the BURNING RAGE at whoever stripped her naked like that.

"Once I find the responsible, be they humans or lunarians, I'll kill ever last one of them!"

That's when she notices a file on a table next to her. It reads "Project Scarlet". Most of it seems to just be analytical babble that goes over her head (not that she cared about such things), but some of it DOES get her attention.

From what she can gather, this facility is the headquarters of a group known as the "P.A.R.A.S.O.L. Corporation" and they seem to be doing research on vampires. The file doesn't say WHAT they're up to, but they call this research project "Project Scarlet" and the subjects of their research are two vampires.

"I'm a vampire, so that's one down. Now as for the other vamp-Wait a minute! This called Project Scarlet, is it not? Then it can only mean..." At this realization, Remi starts to scramble through the files in search of something, ANYTHING to quell her fears. Unfortunately, what she finds only serves to confirm them.

It's a pair of profiles on the two subjects, labeled "Specimen Scarlet #1" and "Specimen Scarlet #2". But that's not all, while they do not include any of the subjects' actual names, they do provide a short description.

One description, a young girl with blue hair and bat wings, matches her own.

The other description, a young girl with blonde hair and "unusual wings, appear to be a pair of branches of unknown metal with seven crystals protruding of each of these so-called wings", matches the description of Flandre Scarlet, her dearly beloved adorable little sister.

In barely contained rage, Remilia says "So they're also holding Flan, huh? They dare to hold not just me, but also my precious little sister? And they dare to strip us naked like that?! Well now that I'm free, I'll make sure that what they did to us will be the very last mistake of their entire, miserable lives!" while clenching her teeth hard enough most humans would've broken theirs.

"So," She thought, "here's what I have to do, in no particular order: Find out what they want from us, kill them, get Flan and leave. But first, I am going to need some CLOTHES!" Remilia exclaimed before starting her quest of answers, revenge, freedom and restored modesty.
