A/N: Hahaha this thing. Um. A long, long time ago I was planning to write a story where the veil sent Sirius into Kingdom Hearts, where Riku was stuck (this was before even Chain of Memories had come out), and so Sirius and Riku teamed up together to escape KH and yeah. I'll probably never finish this, so here's the epic funtimes beginning to a story.

Warnings: Uh…none?

Disclaimer: Still don't own anything. I'm sorry.

Choices

Sirius felt himself falling, falling forever into deeper and deeper blackness. His life was slowly scrolling through his mind, image after image of sadness, fear, and hatred. He wondered if this was the punishment for everything wrong he'd done in his life—the malicious pranks on Snape, the break from his family, the girls he'd only ever played with—if this was what his afterlife would always be. And if it was, why couldn't his punisher have come up with anything better?

An image of Harry struggling with Remus to get to the veil flashed by and he yelped, turning in midair just in time for his feet to touch down lightly on the ground. Light flared from an unseen source and Sirius stared bewilderedly at the stain-glass floor, under which he saw…nothing.

Welcome…to the beginning of your life.

"What?" Sirius asked, spinning around in search of the voice. "Who's there? Show yourself!"

There is no self to show.

"Right. What's going on? Where am I?"

You are about to come to life. Think of this as the womb.

"My life just ended."

Then you are to be reborn.

What was he supposed to say to that? A chance to be born again…to live a different life. To do things right. He lifted his face to a light that had suddenly appeared over him.

"…What do I do?"

Choose.

He gaped at the three pedestals that suddenly appeared before him. Each one had something floating over it: A wand to the left, a shield to the right, and a sword across from him. Each one was the darkest black he had ever seen, with soft silver designs on them—each had the image of a Grim somehow etched into it.

Destruction. Power. Protection. Which ability do you most desire?

He had nobody left to protect, and nobody he currently wanted to destroy. Two steps brought him in front of the sword and he reached up to it. The second his hand closed around the hilt, it disappeared in a flash of light.

And which do you wish to let go?

"That isn't very fair," Sirius pouted, but didn't hesitate to grab hold of the wand—destruction. It and the shield disappeared in the same light.

Your form has been chosen. You will fight for the protection of others. All you need to do now…is walk through the door.

He turned around, and was now unsurprised to see the large white door that hadn't been there before. His mind began expressing doubts, but he knew with dreaded certainty that he couldn't change it now.

The doors opened as he approached, and there was no uncertainty in his step as he walked through to the darkness beyond.

The change in attire was unexpected. Sirius stared dully at his now-gloved hands, and then at his new pants—he could feel a mask on his face, but he wasn't prepared yet to take it off. The black and silver sword was resting in a scabbard at his side.

This is Kingdom Hearts.

"There's an awful lot of shadows," Sirius said, "and they know how to walk."

Are you afraid?

"…No."

You will be.

"What do you mean?"

There was no answer.

Sirius put a hand on the hilt of his weapon and stared into the shadows, trying to decide where to go. But everything seemed to be made of shadows here, and the only direction that seemed better than any other was toward a place that was only slightly less dark than the others. Decision made, he grudgingly began what looked like a long walk.

However, it wasn't long before he swore he heard the sounds of fighting and he quickened his pace, rushing in hopes of finding someone to help him figure out what was going on. What he found was a young man fighting a horde of all types of shadows with an elegance that Sirius had never seen before. He watched, almost in awe at the way the boy cut down each of his enemies until, finally, there was nothing left. Then, turning from the disappearing corpses, he spotted Sirius and practically flew forward, ending up straddling Sirius' chest, blade at his throat. Sirius yelped and looked away from the boy's eyes for a split second, before he remembered that he was human, not dog.

"Who are you?" the boy snarled, a few strands of long platinum-blonde hair falling forward to tickle Sirius' nose. "And what are you doing here?"

"My name's Sirius. Currently, I'm trying very hard not to panic because you seem about ready to kill me when I've just been brought back to life."

"How did you get here?"

"I'm not sure."

"How did you die?"

"I was dueling with my cousin and I…er…fell through a veil. I know it sounds stupid, but it's a magical veil and—LOOK OUT!"

The boy immediately swirled around, swinging his sword, but was swatted away by a humongous shadow as if he was nothing. Sirius jumped up in surprise, pulling his own weapon out as if it was the most natural thing he'd ever done, and impaled the creature on it. It roared and swung at Sirius as well; however, Sirius had clung determinedly to his sword, so it ripped through the monster's body as he flew away. It let out another roar and slammed a fist to the ground, narrowly missing the boy, who was finally up and ready to fight again. As the boy fell from the earthquake caused by the blow, he seemed to let out a bit of his own magic: a fire spell that set the beast on fire for only a few seconds before it died out. The boy stiffly got back to his feet just as Sirius turned into his dog form. He ran forward, fast as his legs would carry him, and jumped, snarling, at the monster's throat. His teeth tore through like it was only paper. He wasn't there long before he felt a large hand grab him, tearing him away from its neck. It squeezed Sirius and shook him around as the boy sliced at it.

Before long, the monster died and released its grip on Sirius. He felt himself falling again, changed back into a human as he did so—and landed on the boy. Through a haze of pain, Sirius thought how the stranger smelled suspiciously like Remus. It was only natural for him to nuzzle his neck and—

"Hey!" the boy yelped. "I'm not a chew toy!"

Sirius practically leapt off of him, finding a seat curled up at his feet. "Sorry," he muttered. "Didn't mean to."

"It's fine," the boy said softly. "Now hold still, you need to be healed. Cura."

Sirius gasped as a soft feeling of warmth coursed its way through his body. He stared at his hand, watching as even the most miniscule cut closed up.

"What in hell was that?"

"Magic."

"But different from my magic. You don't need a wand or anything to focus your power? Just a word and there it goes?"

The boy grinned. "Mickey said you'd need a bit of help with everything. I'll explain. But first we need to find your sword and mask. Come on."

"Wait." The boy turned back to Sirius. "You never told me your name."

"Riku."

A/N: I have no plans to write more KH/HP drabbles, but you never know what I'll do so I'm leaving this story as incomplete.
