Disclaimer: I do not own Harry Potter
Author's note: When I searched up "Harry friends with satan fanfiction" I was like "yeah, satan and harry are gonna do some wild shit lol," and no, it's just fucking romance and bashing and fucking terrible grammar. So, I wrote my own fucking version.
On a midnight, where the silver moon replaced the golden sun, and the dark shadows took over the bright light, a small boy stood in a clearing in a forest, etched before him a pentacle with strange runes brushed over them. White, dripping candles stood on each point of the star, as their flames danced to the wind.
The boy held in his hand a simple knife as he sliced open his forearm. Earning a hiss of pain, dark, glistening liquid dripped onto the strange symbols. A few moments later, the pentacle ignited into a fiery red. Bright orange flames erupted within the circle, and the boy chanted in a loud, clear voice in Latin.
As he finished, a flash of red light illuminated the clearing for a second, and then it cleared. In the circle, a young tall man, looking like about his early twenties, stood there. He wore a black leather jacket, with tall black boots, and faded blue ripped jeans. He had black hair like a raven, black eyes like the darkest night, and his skin glowed like the moon light. Satan, or Lucifer, sighed.
"Look kid," he spoke irritably, "Whatever you have to say, just say it quickly, because I am tired, alright? I know I'm Satan, but even I can get tired."
"I'm Harry Potter," the boy introduced himself, "Would you like to be my friend?" An awkward pause followed.
"If you want a friend, then get a friend besides a demon,"
"Well, er," Harry shifted uncomfortably, "Dudley always scares everyone off, so no one really wants to be my friend."
"Then a lower ranking demon?"
"I tried, but they all laughed at me."
Lucifer stared at Harry. "Then what makes you think I would even consider the thought of being 'friends' with you?" he sneered.
"I can trade you my soul, if you want," Harry suggested. Lucifer pinched the bridge of his nose.
"Look, kid, we don't do that kind of thing anymore. Do you know how annoying it is to hear people screaming in Hell every single day? I do not want anymore people in there."
"Oh," Harry deflated. Lucifer gazed at the child before him.
"How old are you anyway? Three?"
"Five," Harry said.
Lucifer observed Harry. He was dressed in baggy clothes, clearly second hand. He was small for his age, and he was skinnier than a skeleton. Either his parents were poor, or they were abusing him. Lucifer exhaled through his nose.
"You are Harry Potter, correct?" he asked for confirmation. When Harry nodded, Lucifer smiled in an assuring way.
"I can make an exception for you, except you will have to do several things in exchange," he explained. Harry lit up.
"Really? What?"
Lucifer smirked. What a desperate child. So pure, unaware that a hidden world thought of him as their savior. So corruptible. And not in a dirty way, you disgusting people. Satan has more style than that.
"As your 'friend', it is my responsibility to make sure you can grow into the very best you can be," Lucifer explained, "So, as you seem to appear to appreciate the Dark Arts, such as occultism, I will teach you everything I know, such as how to summon the dead, command the horrors of Earth, and the ability to familiarize yourself with the shadows. I can also teach how to manipulate people, to bend them to your will, while maintaining the image of an angel. Under my wing you will learn how to bring forth the fear within people, and draw out the dark side of them. Everything I know will be passed down to you. Understand?"
Harry nodded excitedly. "Yes!"
Lucifer cackled. He couldn't wait to see the reactions of the witches and wizards of the magical world when they figure out that the Boy-Who-Lived became obsessed with the Dark Arts. Oh, this was going to be hilarious!
"Say, kid, where did you get the book?" Lucifer asked.
"From the library."
"...the library."
"Yeah."
"You summoned me, the King of Hell, with a library book?"
"Yeah."
"..."
"Can I call you Lucy?" Harry asked.
"...Lucy."
"Yeah, Lucy. I can't really call you Lucifer in public."
"Why not Lucius?"
"What's wrong with Lucy?"
"Because it's not a cool name!"
"Sure, whatever, Lucy."
