A/N: I have adopted this story from 'A Certain Random Guy'. If you want to read the original it is called 'The Faceless Familiar'.

Louise waited for the smoke to clear around the summoning circle and noted that she unconsciously started praying for the Founder. Praying that she summoned something something powerful? That she didn't kill whatever she summoned with the explosion? That she actually summoned something at all? That she didn't know...

What she Louise know was that someone used a wind magic to clear the smoke and let her see the results of her dedication. Then, she saw said results in the form of a man, a man in shining armor that lacked the extravagance of a noble's which had jewels and gold lining. Though it was still clearly better than that of a mercenary. The design and inscriptions looked like the armor someone would wear in a crusade.

The man stood tall before her as she took a better look at him starting from his feet, that were covered by pointy sabatons that looked brand new, still shiny and polished. Her eyes went up to the greaves that fit all too well for a piece common armor, meaning it had been custom made. This led Louise to believe that she had either summoned a poor noble or highly respected knight. The greaves had inscriptions of different runes that went up to the kneecaps.

On the large round metal sphere which protected the kneecap, supposedly the poleyn, the runes circled around the middle of the knees and then continued on the way up. She took a second to analyze the runes but didn't recognize them, so Louise kept her vision going up until she was eyeing the cuirass. There, a large inscribing of runes covered the breasts and she recognized them as the kind of runes that generally appeared on familiars, the only letters she recognized were G, A and F.

With a glance she noted the arms and even the gauntlets were all covered in the strange runes and in what must have been optical illusion she almost felt they were moving slightly. The man didn't carry a weapon, or at least none she could see, so his hands were simply hanging on the sides of his body. Finally, Louise looked up to the man's face, only to be met with a closed helmet that was also covered with runes. The runes went into straight lines up to the top of the helm, probably finishing all at the same point on the top which her height did not allow her to view.

The helm had a small, almost non-existent opening to allow the man to see, but she could not see his eyes through it. Although, it made her wonder if he could see anything through it. They stood like that, completely silent and still for what felt like an eternity, before the man decided to move. Or so she thought, as he appeared to shrink before her and everyone else. If she didn't hear the gasps from her classmates, Louise would probably have thought she had gone crazy.

Knights didn't suddenly become shorter along with their armor. But there in front of her the man Louise had summoned was doing just that and now she could actually swear the runes that covered the entire armor were moving, shifting on the metal as the space available for them was diminishing more and more. It finally settled when the figure whose gender she couldn't actually discern, stood exactly at the same height as her, their eyesights lining up perfectly. Then, it spoke.

"So, summoner, for what reason was I brought here?"

What came out was in the exact same voice as Louise.

'Wait, I said that?'

Wait, no she didn't. So why did she hear her voice ask that question? She looked surprised at the thing that she summoned when it raised the visor of its helmet. She saw herself. Somehow, the person in front of her was Louise de la Vallière, wearing that strange armor. The other Louise took her helmet off, and the pink hair flooded down her back just like it did over Louise's cape. In complete confoundment, Louise stared at her summon.

"H-how?"

Even if she was a failure at practical magic, Louise was the best of her class, rather, the best of the school. In any theoretical field she knew anything and everything through hours of devoting herself to reading and studying in order to ace the theoretical examinations. She had miraculously made it to her second year with an expected zero for the practical and a jaw dropping hundred for the theory. Since they took the average, she had just barely been allowed to advance.

Right now, her mind was already working to understand the scene before her. Louise had spent the last week studying the different kinds of beasts that could be summoned and even ended up looking up on beasts that were supposedly unsummonable in preparation for her summoning. There was, only one such creature that matched what she had summoned. The demon that was the perfect double, that could steal a person's identity and wear as a second skin…

It was then that the figure before her replied.

"How? It should be obvious, considering you summoned a Doppelgänger..."

The other Louise cemented her theory. She had done it, she was somehow able to do something no one had ever done before and summoned a demon to be her familiar. She could already hear the gossip starting between her classmates and even Professor Colbert, the kind teacher that, different from every other, continued to believe in her, that continued to believe that she had potential for magic that simply hadn't been revealed yet, seemed startled.

He recovered from his shock quickly and held his staff, ready to use magic to attack the demon. Louise couldn't blame him really. If it was, indeed, a Doppelgänger before her, it would need to be killed before it could hurt someone. It had to be killed quickly before confusion spread and it escaped under the guise of another.

Doppelgängers were different from other demons, they weren't much stronger than humans both physically and magically. Though even a demon like that could probably still kill her before she could notice, then proceed to take her place as Louise Françoise Le Blanc de La Vallière. She was afraid but stood firm as the demon spoke.

"So, summoner, I repeat my question, for what reason was I brought here?"

Louise quickly listed the possible answers she could give in her mind. Maybe she could tell the demon that it was all a mistake? But she couldn't reverse the summoning, so that wasn't a good idea. No, the only thing she could do was tell the truth and hope that the demon wouldn't kill her. With wavering confidence, she answered.

"I...I s-summoned you to serve as my f-familiar."

The Doppelgänger looked at her with an eyebrow raised. Louise closed her eyes and waited for the worst, trying to think of happier possibilities. Maybe it would be a painless death? Or Professor Colbert might even take down the Doppelgänger before it attacked her! Maybe it wouldn't be so pissed and would let her go?

For a time that felt like an eternity there was only silence and then she got her answer. It came in the form of a loud laugh from the demon. Louise opened her eyes to see her double laughing with an enthusiasm she, as a noble lady, would never reach. Looks like the idea of being summoned to be a familiar amused the demon somehow.

His laugh kept everyone else around petrified. They weren't dead, so maybe the summon wasn't going to kill them. But then again, if they interrupted the laughing, that might change. That was the thought that went through everyone's head as the armored double guffawed for a minute before finally settling down and speaking to her.

"That was a good one, girl. I seriously can't be sure if you are incredibly bold, or ridiculously stupid. But to be honest, and that's a lot coming from one like me, if you were even able to bring me here, without any catalysts and unintentionally at that, I wouldn't mind forming a contract with you. Now, what are you willing to give me for my services?"

That shocked Louise more than everything that happened up until that point. That powerful demon deemed her worthy? He was actually willing to be bound to her? That was more than she could ever ask for. But now she had to be cautious. For all she knew, the demon could change his mind in an instant. She tried to form a list of things she could offer, trying to think of something that could win over the demon.

"I-I will give you shelter and food..."

Louise trailed off for a moment, thinking about anything else she could actually offer. She remembered demons usually needed magical energy to exist.

"Also, I will provide you with energy from the contract and… Pay for things you ask, if reasonable..." Maybe she shouldn't have added that last line? It could be interpreted as a preposterous demand from her, right? The demon chuckled lightly before answering.

"Those are reasonable terms for a contract. Shall we proceed, then..."

That was her cue. Before he could back down, she raised her wand and announced the binding words.

"My name is Louise Françoise Le Blanc de La Vallière. Pentagon of the Five Elemental Powers, bless this humble being and make him my familiar."

At that, she got closer and kissed her own double. A small part of her mind noted how interesting a story that would be later if her kids asked, how her first kiss was taken by herself.

As their lips separated, a faint glow left the spaces from the Doppelgänger's gauntlet, the rune symbols probably appearing at the newly branded familiar's hand. Said familiar smirked before proclaiming just as she had.

"I, Unbekannt, The Oldest of the Doppelgängers, accept your terms, Louise Françoise Le Blanc de La Vallière. We are now bound to one another, until death tear us apart..."

And with that it was over. Louise had summoned a familiar. It could be beautiful if it so wanted and there was no denying it was powerful but it was about the furthest thing from holy you could get… Big Sis Eleonore would be pissed, of that she was certain...
