My POV

I am floating around in a limbo.

I remember dying, I had gotten sick and it got too serious, none of us could do anything.

I think it was that damn Covid-19

I am floating, an empty void, why did this happen?

"I wish there was more to my situation than this." I had said into the empty, meaningless void.

Suddenly a place begins to draw itself around me.

"Is this my home's entrance?"

I then noticed I was naked and suddenly felt a rush of embarrassment.

Just as I thought that, a set of clothes appeared, I was surprised, but put them on.

Where was I? This place resembles Harry Potter's Limbo.

"Well, hello there, nice to see you again." A very familiar voice said

"Auntie?" I said in shock.

"Yeah, it's me." She said

"What are you doing here?" I said.

"I came to collect you. You have died."

"I have died." I repeated. I had trouble believing it, but then again, I did remember fading to black quite clearly.

"Say, if this is Limbo, then can I?" I said, before extending my hand, a screen appearing before me.

I focused the TV on where I wanted to go.

"What are you doing, (censored due to being my real life name)?"

"I just want my death to be the next great adventure" I said, remembering Dumbledore's words in Harry Potter, in the screen there was a "fictional world".

"Ahh, Familiar of Zero, just the body I want."

On the image was Louise's mother, and I wanted said daughter's body for myself.

Along with that wonderful Void magic.

Concentrating I willed a door to Louise body to open and made it so I would come back to Limbo upon dying again.

I stopped, Louise had it pretty though, was I really willing to slip into her shoes?

I guess so.

"I'll see you eventually, auntie Fina"

I then walked through the door.

…

It had been 17 years since then and it had been damn tiring.

I was eagerly waiting the Spring Time Familiar Ritual.

I was an absolute failure at magic. At least, this world's system, over time, trough adamant study and practice, I eventually learned the Harry Potter method but for obvious reasons, I couldn't use it in public.

So I've always been Louise the Zero.

Now, I've never given two shits about this world or (most of) the people in it, but after a while it got very old. And I spent years of this shit.

I spent a lot of time in my Room of Requirements, it had taken me many years, but I finally pulled it off.

After completing it the first thing I did was try to get into contact with Harry Potter.

A ridiculous idea, I know, but I did it while he was with the Dursley, and desperately needed affection.

He even asked me to become his sister, imagine that.

I said yes, of course. I was frankly intrigued and the boy was quite clearly starved for affection.

As for the subject of the familiar summoning.

I wasn't going to use the same summoning charm canon Louise used to summon Saito because I don't know if this is the canon universe. The Summon Servant spell is many things, and safe is not one of them.

Never raise that which you cannot put down and all that.

I'll probably get Saito anyway, but since in each fanfic she gets a different familiar, I don't know what I'll summon, I have to take some precautions.

I already have one.

I'm staring at the humongous black serpent demon I had managed to summon, that I still don't know what it, err… he is.

"So tell me, Lerothopet, can you shapeshift, or at least size-shift, because unfortunately, your size is an issue."

"Yes, I can, master." At which point Lerothopet started shifting until he resembled a blue eyed, handsome human teenager. He was dressed like an ancient pharaoh.

"He looks a lot like how a realistic Saito would." I muttered, then I turned to professor Colbert.

"Professor, can you please heal my familiar from the injuries he still has."

"Yes, of course, miss Valliere. Please come here my young man." I was pretty pleased with the fact that he referred to Lerothopet (that name sounded Egyptian, actually) like a person, rather than a monster.

My familiar went up to him and he said a spell. The rest of his injuries began to heal.

"Thank you." Said Lerothopet.

Very polite, I like it. Nonetheless I have questions. Very urgent questions,

I went over and grabbed Lerothopet's arm before bowing my head to Colbert.

"Thank-you-Professor-I-need-to-talk-with-my-familiar, Ciao" Then I dragged him by the arm away from the crowd of people.

Once we were far enough I said to him.

"You got a lot of explaining to do to me."

"Of course master, but we shouldn't do it under Ra's watchful glare."

"Ra?" I whispered, confused. Did he mean the Sun God?

Lerothopet's POV

"Who 's Ra?" Master whispered I could smell she was confused, just like how I could tell she was terrified earlier.

Sensing emotions was a trait many gods of chaos have, but how could she not know the enemy of all demons?

Demons like the two of us.

This couldn't be allowed, she was putting the both of us in great danger, more than she seemed to understand.

"Master, we got to discuss this indoors." I whispered conspiratorially. "Away from the sunlight, HE already has seen too much."

Master looked at me, then nodded tiredly, I took that as a good sing.

As we walked into the palace I began to wonder why Master didn't seem to know anything about the pantheon.

How? Why?

He thought a lot about it and of several theories he came with one that made the most sense to him.

She was a newborn God, who most likely knew nothing about her true self or the status quo of the world or the conflicts between Isfet and Ma'at.

This… couldn't be allowed, again, she was in so much danger it wasn't even funny.

I rubbed my hands against each other in nervous worry.

Looks like I'll have to give her a crash course about her true life, the universe, and everything.

But first I need to map out the castle.

_-…..

I'll end the chapter here. Now I want to make a few clarifications…

First of all, Lerothopet isn't real Egyptian but I'm taking some artistic liberties.

Imagine it means something similar to "He who left for peace" representing how he will somewhat find inner peace by being summoned and becoming Louise's familiar.

Next, I'm sure you've noticed I added Harry Potter to the cross over.

This is actually a cross over with the Mr Black verse. I chose to do it because the big fun of this story is watching the misunderstandings pile up, with everyone coming up with zany theories to explain the heroes. And what story displays this better than the Mr Black verse?

Also one last thing, last chapter, when I said Lerothopet stood up I meant that he lifted his head a few meters from his coiled body like snakes are famous for. That Apep was sometimes depicted with legs doesn't mean he or his descendants will have them here.
