This is the first chapter for a new story I'm about halfway through writing. I'm pretty happy with this chapter but it's still libel to change as I keep writing.

To answer any questions you may have, this story is going to be a one off, so no squeals. There may also be some character deaths but I haven't decided yet.

Regarding the main character, he's the same person as in my other story 'Origins' but with a different outlook on life. When I first came up with the idea for 'Origins' I had intended to have Nameless as a bad guy but I wrote him as a hero instead. A while later I remembered that I had wanted him to be a villain so I started writing this story. So he's the same character, just with a new name and a new purpose.

The story is set at the start of Buffy series 3 and some time before the events of Kingdom Hearts 1.

1: Arrival.

Most people suffer from a common misconception : that they know everything about their world. Take the residents of Sunnydale for example. Nine out of ten of them firmly believe that there is nothing wrong with their town, despite all evidence to the contrary. There are a few however that are aware of the supernatural, Vampires, daemons and all manner of strangeness.

All of these daemons' know that surrounding the human world are countless daemon worlds looking for a way in so that they can wreak havoc.

But this is also a misconception.

The human world and daemon realms are in fact just one world. A tiny islet in a vast ocean. There are only a few that know of the existence of other worlds and fewer still that can actually reach those worlds.

Unfortunately for the residents of Sunnydale (and the rest of their world), not all of these people have good intentions.

In one of Sunnydale's quite back ally's, in the middle of the night, reality shifted slightly. Then split open. A dark portal appeared where there had previously been just empty space. Two new begins walked into Sunnydale. One a man dressed in a brown cloak that completely obscured his features. The other was a boy dressed predominantly in black, trousers, shoes, shirt even the leather jacket he wore.

"Ok" said the boy, breaking the silence. "Now...now I'm impressed."

The two walked out of the ally into what appeared to be a high street. Most of the shops were closed but a few were still open, serving those few people brave or foolish enough to venture out after dark.

"I can't believe it. This really is Sunnydale isn't it. Ha!" The boy looked around, awestruck by his surroundings. He was in a whole new world. And to top it off, it was one he knew well. "How can this be Sunnydale? This is on TV, how can it be a real place?" he asked his companion.

"The stories of worlds often find a way to reach another." replied the other man."Your world is unique though. It hears so many stories."

"K. Makes 'bout as much sense as the rest of this."

The pair rounded a corner into another ally. The man in the cloak lead with the boy following close behind. "So this darkness stuff, it makes me better right? Stronger, faster, tougher..."

"All of these things and others besides. Right now your abilities are...limited but you have the potential to be stronger. In time." said the man in a matter of fact voice.

"liking the sound of that boss." replied the boy. He looked up quickly, enhanced hearing picking up noises from ahead. "Trouble."

A little further down the alley their path was blocked by three vampires. They were standing in a line, facing the duo. Evidently they'd wait here for people to walk down the alley then attack them. Boy were they in for a surprise.

"You boys take a wrong turn?" asked one of the vampires, a large male.

"Don't you know this town ain't safe after dark?" joked the groups only female member.

"A perfect opportunity for you to test your new powers." said the man.

The boy smiled and began to walk forwards, needing no further encouragement. "Aye aye".

A black aura enveloped the boy as he moved towards the vampire trio. There smiles had faltered slightly but they still stood their ground. They jumped back when the boy jerked out his arm, causing a sword to materialise in his hand.

The sword had a black metal core with a purple crystal forming the outer blade, with two short protrusions on either side of the blade.

The boy spun the sword in his hand, testing its weight. Satisfied he turned on the vamps. "Tremble in my darkness!"

He lunged forwards in a blinding burst of speed. The two male vampires were dusted instantly, cut down by the black sword. The woman lashed out striking the boy across the face. His head jerked to the right but he was otherwise unphased.

The woman looked confused that her attack had done nothing. "Ha ha ha ha. Oh, pain is my friend." The boy grabbed the woman by the neck and lifted her off the ground. "Allow me to introduce you to it." The boy rammed the sword through the vampires rib cage, she disappeared in a cloud of dust.

Satisfied with his handiwork, he turned back to the other man. "How'd I do?"

"Brutal and unrefined. But promising none the less."

"Ok, first I need to figure out when this is. Seeing as how this town isn't a crater its before the First Evil attacks so..." The boy paused for a moment. He knew he had forgotten something but he couldn't remember what. "Oh...right. Getting ahead of myself."

The boy whistled. Answering the call were five neo shadow Heartless that rose up out of the ground behind him. "Find this worlds heart, and do what you do best." The heartless dashed off out of sight, following their masters orders. "Now that's sorted I can get down to business. Finding Buffy Summers."

"Remember that you are here for a purpose. Not to indulge you childish need for amusement."

"Oh, don't be such a spoil sport. The Heartless are looking for this worlds heart and I haven't forgotten why I'm here. Have I given you a reason not to trust me yet boss?"

"Not yet."

The man turned away, heading towards a black portal that had just appeared behind him. "Don't forget your purpose here." he said before vanishing, leaving the boy alone in the ally.

"Whatever you say Ansem."

"Here vampires, vampires, vampires!" called Buffy for what felt like the hundredth time that night. Buffy Summers was on her nightly patrol in the Sunnydale cemetery, looking for any Vampires that needed a good dusting. Unfortunately no vampires were obliging her need to hit someone.

It had been months since she'd been forced to kill her lover, Angel, to save the world. And only a few weeks since she arrived back in Sunnydale. Seeing her friends and her mom again, plus all the feelings about Angel were weighing heavily and she needed some kind of release from all the stress.

"Buffy?"

Buffy spun round to face the speaker. It was a boy, tall, thin with pale skin and black, spiky hair. He was dress completely in black except for a red symbol on his shirt. It looked sort of like a red heart with a cross though it.

"Buffy Anne Summers?" asked the boy.

"Yes. Who are you?" asked Buffy.

The boy smiled slightly. "Oh, I'm your worst nightmare honey."

"Really? Because you don't look like next week's history te-" Buffy was interrupted when the boy lunged forward. She raised her arms blocking his punch. He was fast and strong. Stronger than any natural human. Buffy grabbed his arm then flipped him over, smashing him into the ground. Then she got a look at the boys eyes. The pupils were an unnatural shade of bright yellow.

The boy jerked up and resumed his attack against Buffy. Now that she had recovered from the initial surprise for his powers she was having a far easier time. Buffy blocked every punch then lashed out with a kick of her own. The boy was knock backwards, breaking a tombstone as he went.

For a moment nothing happened, Buffy just stood where she was, bracing for another attack. Then he staggered to his feet. He wobbled for a moment, then he looked right at Buffy. "This isn't over nemesis. So swears..."

The boy trailed off. Before he'd met Ansem the boy had no idea of the dangers of using darkness. As a result it had obliterated most of his past memories, including his real name. If he was going to pick a new one now would be the time.

Nameless, or No-name. No. Those were obvious and stupid. No-Heart? Even worse. Heartless? Ansem had told him about the Heartless. There were many different types, all built for battle. But the biggest and baddest of all were the...

"So swears Darkside." with that he turned and limped away, punctuating every step with an "Ow".

Buffy shock her head. She thought that she'd seen the weirdest this town had to offer. Well, if there had been any vamps about they would be long gone now. Buffy turned and started on her way home. Her mother worried if she stayed out too late. Plus tomorrow was a school day.

The newly named Darkside watched her go.

"You held back." He jumped at the voice behind him. Ansem was standing there. How long had he been watching?

"I wanted to test her strength. Plus now she thinks I'm a joke. So when I show my true colours she won't see me coming." Darkside walked off, losing his false limp. Buffy's punches had hurt, but they were nothing serious. "Right now I need to find somewhere to sleep. Then tomorrow its back to school, for a little...experiment."
