hey im posting this for some reason, I got the idea from watching Kuroshitsuji 2 and I always was baffled by the fact that Claude looked liked the illegitimate child of Sebastian and William and i got this idea stuck in my head. I don't know if ill continue it, only if people want me to. this is short im sorry but I always post chapters over 1000 words long or more. this story is set during the early years of 1000 during the viking area. I did this because I wanted Claude to be old in kuroshitsuji. im on FANfiction, im 100% positive I don't own Black Butler/Kurshitsuji! well I hope you enjoy it.

Chapter 1: Sealing the Deal

William T. Spears rubbed his sweaty hands together trying to dry his sweat-clad hands. He walked around the abandoned area of the village trying to sort out his thoughts. He knew if the higher-ups found about what he was planning to do, well he didn't want to think about it. The moon was his only light source in the blackening sky. He was about to commit a taboo, but he was only so young and the Shinigami training's are incredibly difficult, he wondered if even doing this was even worth the possibility of being caught out.

He abandoned the thought immediately, he was already anxious as it was and he didn't need to doubt himself, he made up his mind to do this and he was committed to this. But as the baleful and dark aura of a demon suddenly appeared behind him he tried to hide his doubt and fear away but as he turned to face the demon he froze. His eyes widened and he internally scolded himself for summoning a creature of hell.

Remember you need to pass training this year, you don't want to be failure and have your peers laugh at you when you don't pass! He gulped audibly and he took deep breaths to calm his rapid heart. He swore he saw the devilish creature's mouth raise in a large smirk, the glowing slitted pink eyes boring into his soul. "So what's a shinigami doing summoning a demon like myself?"

The devil's voice oddly didn't suit him. It made him think of honey. The demon looked absolutely disgusting, he realized that it was the demon's true form. The large skeleton bird-like wings looked bloody and bruised and he was surprised the raven-like feathers were still on. The large fangs protruding from his teeth were sharp and look like they could cut through metal. Curved horns protruded from the demon's skull and the demon's fingers looked like long claws. The rest of the demons body just sent chills of cold shivers down his spine.

When he opened his mouth to talk, his words got stuck in his throat and refused to come out, making him gape like a fish out of water. He counted to ten in his head, breathing deeply, and forcing the words out before he lost the courage. "I need your help. I need to pass my training but im positive im going to fail the physical part of the examination."

He looked up at the demon slightly surprised to see an amused look in his eyes. "I might have not lived as long as other demons but this is a first I've seen a shinigami asking a demon for help. I'm sure if your trainer ever found out about it you'd be kicked out of dispatch," the demon circled the god of death. William nodded grimly, he had already thought about that. "But the real question is: what will you give me in return?"

This made William's thoughts stop dead in their tracks as he internally cursed himself at his stupidity. Of course you moron, he scolded himself. Demons make contracts. They don't just give their abilities to humans for the hell of it. The demon raised his eyebrows, laughing," well by the looks of things you didn't think this through enough." To be honest I didn't think a demon would even come.

"Well you can cross off the soul. Shinigami have very unappealing souls and im not really all that hungry. But what do you have that a fiend of hell would be interested in? Humph?" William frowned in thought, what did demons normally want in exchange. Souls? Yeah but the demon doesn't seem interested in it. Well if humanity is correct, they like things untainted and innocent. It's worth a shot. "My virginity?"

The demon paused and looked like he was seriously considering demon tapped his clawed index finger against his chin and seemed just to do that knowing it was making the god of death even more nervous than before. William knew the demon was making him wait on purpose. Maybe he's not interested but that's all I can think of. I have nothing that could entertain a demon. But I have to think of some–

"It's a deal," the demon said. William looked up sharply, perplexed that the demon had actually agreed. William looked at the clawed hand held out to him. He hesitantly shook it, trying to dodge the three-inch long claws. Well there goes my virginity. As he took his hand back, putting it into the pocket of his winter jacket. So what now?

"The deal is that I help you pass this examination and you'll give me your virginity," the death god nodded disquietly. "Now its time to place the contract seal on our bodies, the more visible the place the stronger the power. So where do you want it?" the demon recited. The shinigami looked at the sheath that held his death scythe and looked back at the demon, "my hand, I want on my hand." The demon nodded, walking slowly towards his new contractor his body shifting to a body that looked more like a shinigami: shoulder length raven black hair, the trademark golden and green eyes and a tall, broad shoulders and long legs that made the demon a few feet taller than William.

The demon pulled out William's right hand and a burning pain spread from his hand. He bit his lip to repress the cry of pain. Then just as quickly as it came, it vanished. But what was visible was a large pentagram with satanic writing inside the star and in the inside circle. He looked at the enigma in wonder rubbing over it with his other hand, not feeling anything but skin. "What's your name?" William asked, not relishing calling the devil 'demon' out in public.

"Call me Asmodeus," the demon said with a large ear-to-ear smirk.

now if I confused anyone, Asmodeus is actually Sebastian, i didn't give him that name because this is 800 years before Ciel is even born and Ciel is the one to give Sebastian his name so briefly Sebastian will be called Asmodeus- which happens to be a name of an archdemon so review me if you want me to continue this story and ill try to update ASAP :)
