Disclaimer- Some really cool/rich/genius Japanese guy owns YYH. And... well.. I'm not even a guy.

A/N- Well, here it is; after watching the last episodes of YYH, I came up with this lovely reunion fic. Only, it's so much more. It will, actually, be centered around Koenma. If things go according to plan, there should be a sequel once this thing's done and over with.

The unboldsentance is no longer true. Sorry!

Pairings- Yusuke/Keiko, Kurama/Shizuru, Hiei/Mukuro, Kuwabara/Yukina, Koenma/Botan... and I think that's all the important people...


Time and Time Again: Chapter One
On more than one occasion Koenma wished he was nothing but a simple human, free to enjoy the sunshine and fresh air whenever he pleased; this was no exception. The demi-god sat behind his desk, going over papers and stamping them with the lightning speed gained from several hundred years of practice. The screen across the room was black and silent, and even his ogre seemed to have vanished in his trip to get more papers to be reviewed. Sometimes Koenma felt so alone...

It was just after the Reikai Tantei was disbanded that he decided to make his adult form his general appearance, rather than remain a toddler. He had to admit he didn't get quite as many odd looks about the pacifier in the younger version of himself, but the questioning glances were still limited now that he appeared older. He received more respect now; never before had he basked in this much, particularly if the Reikai Tantei had been involved.

The Reikai Tantei.

Koenma sighed, pausing in his paper pushing and stamping. As much as he wouldn't admit it, he missed all four of them dearly, even if they had rarely gotten along. The stamp fell from his hand, landing on the pad with a thump. The papers slid from his other hand and he slumped back in his chair, covering his face with his hands. It seemed like just yesterday he was lecturing Yusuke on the Spirit Egg... But it had been over twenty years ago that he had been informed that Genkai had left them all her temple. Things had just never been the same, and he hadn't ever seen any of them, save Boton, ever again.

Speaking of Boton... Where was she? The ferry girl had said something about information on a new demon possibly plotting domination of the human world. Not that he would pay much attention, but still, the bubbly girl had an unusual knack for punctuality. Shaking his head as if to rid his mind of haunting, yet pleasant, memories, Koenma stood and headed for the door. He turned the knob and opened the red door, expecting a sudden flurry of noise, papers, and ogres. Instead the hallway remained deserted and quiet, almost as a living soul had never set foot inside. Which, in reflection, was almost true. It was, after all, the Spirit World.

"Hello?" Silence greeted his call. A puzzled expression darkening his features, he slid further into the hall, unsure of what to expect. Something strange was going on, however, and he was determined to get to the bottom of this. Whatever this was. "Hello?" Koenma paused, contemplating which direction to go. The right path would lead to the ferry girl exit, where the 'grim reapers' took off to lead departed souls to Spirit World, and the left path would take him to the jumble of ogre offices; if anyone was left in the castle of places, the offices is where they would be.

As Koenma marched down the hall, arms held behind his back, he had the feeling someone was watching him. The hairs on his neck bristled as he suddenly spun around, arms poised to fight if he really, really needed to. However, there was no one there. He blinked, lowering his hands as he gazed suspiciously about the corridor. Shrugging it off as paranoia (he had, after all, recently viewed a human horror film; maybe he still had the jitters), he returned to his meandering down the hall, shoving the sinking feeling to the back of his mind.

It was only a short while later, though, when the eyes on the back of his head feeling returned. Koenma was now dead set on ignoring it, telling himself it was all in his head. It's only my imagination... No one could possibly sneak into this place... It's too heavily guarded... And yet, despite his self-reassurances, the shuddering feeling grew. Before long it was too strong to stand, and Koenma found himself whipping around once more. Like before, the hall was completely deserted. His sharp breathing echoed almost silently off the walls as he gazed wide-eyed into the emptiness. What was going on?

Koenma turned sharply on his heel, marching off for the offices, his pace quickening. Now that he thought about it, he couldn't sense anyone around. It was as if they had all... disappeared... He closed his eyes, willing the dreadful feeling away. His stomach twisted and turned, unsettled to the point he felt he might be sick. Something was very, very wrong. The grimace still firmly planted into his features, he arrived at the office door, and a with a slight push shoved the door open to... nothing.

"Where did everyone go -" Koenma began, cut off by a cold, clammy hand gripping the back of his neck. He choked back his words, his adam's apple bobbing as he took a deep swallow, eyes wide in fear and disbelief. This is just a sick joke... Yeah... That's it... a joke... nothing more...

"This is no joke, Koenma." The voice was high and cold, causing an involuntary shudder to revolt through his body as the unknown foe spoke his name in such a mocking manner. "This is very real."

"W-what do you want?" Koenma managed to muttered, sweat forming on his brow.

"Countless times you've managed to have someone thwart all our plans," the voice hissed, low and threatening in his ear. "This time we won't let you."

"Who's we?" He asked, regaining a bit of his cockiness.

"You'll remember soon enough, I think." Koenma's cockiness evaporated, leaving the demi-god with nothing but fear. "And without anyone to command them, they'll never know. You'll soon be forgotten, and then we'll take over."

"Take over what?" Koenma question, his voice trembling with every syllable.

"The Human world, of course... But once that happens, you'll come back into the story... As the man.. or toddler... that stepped aside and allowed the world to crumble beneath his feet. They'll all hate you... every last human who as ever known of your existence. They'll want you dead; all of them. They will beg us to kill you... And then... we shall."

"Someone will stop you!" Koenma growled, his face contorted into an expression of absolute fury.

"With you out of the picture, they'll never know before it's too late..."

"No!"

"...Your Spirit Detective can't save you now..."

With a last gasp, Koenma felt his stomach and head sear with endless pain, reducing to a pounding numbness. Before the absolute darkness consumed him, the Prince had one last, fleeting thought.

...Yusuke...
