A/N Yes I will be finishing this up ASAP, with only a couple more chapters, at the most, to get it done before Halloween. This was just an impulse, after all – but I still hope you enjoy it!

I don't own Naruto, or Sasuke, Kakashi, or Itachi. If I did…well. Wouldn't that be interesting xD

Warning – shonen ai.

"And please, Kakashi – come back tomorrow with no more of this supernatural stuff, okay?"

He sighed and nodded to Tsunade before walking out into the twilight again. They had spent the entire day examining Romzai's body, as well as the bodies of the three previous victims. True enough, all the symptoms were the same – flour-white skin, severe scratches, terrified expressions, and those two unexplainable puncture wounds. Kakashi's vampire theory seemed less and less unrealistic as the evidence added up, but no one believed him. The families of the deceased were appalled that he could even mention such childish fairytales when such a serious serial killer was on the loose. Besides that, there were no other possible leads – the only evidence was the similar looking scratch marks on the floors and walls and that scrap of black cloth from the day before.

To make matters worse, two more victims had been discovered in the morning – both young girls, both murdered sometime during the night.

"Tomorrow is Halloween," Tsunade had said in a pleading tone. "I feel like this has been a warning…and tomorrow will be when they strike the hardest. Please, please – scour the town tonight! Don't let anyone else get hurt!" She had put together a number of ANBU operatives to prowl the streets as well, but she asked Kakashi to especially watch over the most dangerous areas. She trusted him.

Kakashi wasn't exactly sure what to do. He just started to walk, his footsteps quieter than a snowflake gliding to the ground, keeping his eyes alert. The moon was a full one now, larger than reality let you imagine. The rest of the sky was pitch black – no, it was darker than black. Something seemed to have turned off the stars. An icy chill made Kakashi pull his vest tighter and fluttered dark leaves past his hair. No one was on the streets – Tsunade had warned everyone that the night was no longer safe.

It was not a friendly atmosphere.

Kakashi wished he could have worked with someone else, even…hell, even Jiraiya or Gai would have been better than patrolling the depressing streets alone on October 30th. But of course, three- or two-man teams were much more conspicuous that one-man ones, and Gai wasn't exactly the most stealthy person ever.

He checked his watch. 11:52, it blinked at him. He sighed. Just over six hours before he could back and report to Tsunade. Or something like that. She had told him his shift was to be from 11:45 til dawn.

Alone with his thoughts for six hours, searching for a terrifying murderer. Oh, the joy.

To stave off boredom, he tried to think of possible ninjitsu that could result in corpses like Romzai's and the rest. Unfortunately, this always resulted in a certain passage running through his head.

Vampires do not favor the sun. Though it will not kill them upon contact, it drains most of their power. Therefore, vampires are strongest at night, or in dark places.

All the murders had been at night.

Vampire murder victims, therefore, are those who have been drained off all of their blood, giving them a pale appearance themselves.

All of the victims had been unnaturally pale.

They prefer blood coming from a still-beating heart. This is why they enjoy "playing" with their victims before the bite – it gets the heart pumping faster, causing more savory blood.

Well, that wasn't enjoyable to think about. But still! Kakashi ground his knuckles into his tired eyes.

"It all adds up!"

Oh shit. He didn't mean to say that out loud. His words stabbed the silence, echoing almost obnoxiously into the darkness. Instinctively, he crouched low, his eyes scouring the streets in all directions for any sign of movement or danger. The streets remained empty, and he breathed a sigh of relief.

But the danger wasn't on the streets.

"Looking for me?" An all-too familiar voice hissed somewhere above his head. Before Kakashi could move, scream, or perform any sort of technique, he was flat on his stomach with a heavy body on top of his.

"Wh—AAAAARGHHHhhmmmmph!" A blazing pair of eyes drilled into Kakashi's head, and suddenly he felt all his strength, all of his chakra, draining out of him. He tried to scream, but a firm piece of cloth was being woven around his mouth. He could only helplessly let himself be dragged away somewhere by his unknown attacker, staring furiously at the unhelpful stars.

After what seemed like an eternity, Kakashi felt himself tossed roughly against what he judged to be a treetrunk. His attacker crouched down low, kneeling very close to the immobile prisoner. He tilted his head up and Kakashi let out a muffled yell.

"Did you miss me, Hatake Kakashi?" Uchiha Itachi's voice slithered into Kakashi's consciousness. "You didn't think I was done with you, did you?" Scarlet eyes gleamed with an animalistic glee as thin white hands unwrapped the cloth. "Do you like my new Sharingan trick?" He gestured towards Kakashi's paralyzed body. "Full Body Immobility. Comes in useful sometimes."

"Uchiha Itachi." Kakashi whispered. It was no use screaming; he knew they were miles away from the village. Still, his mind was racing – he had fought Itachi before and came out alive, maybe he could do it again. He needed to buy time though, until the damned Full Body Immobility wore off. "Are you going to kill me?"

For the first time, he heard Itachi laugh. It made the hairs on the back of his neck stand up. Something about the laugh seemed…inhuman. And then he saw them –

Fangs.

They couldn't be actual fangs, obviously, since vampires didn't exist. Yet there they were, gleaming menacingly as Itachi threw his head back.

Kakashi didn't remember doing it, but he suppose he gasped, since Itachi stopped laughing abruptly and looked down at him.

"Surprised?" His face was inches from Kakashi's, and there was no denying it now – they were fangs, and they were bared. "You shouldn't be. The evidence has been adding up, Kakashi, I know – I planted it. I wanted you here tonight. I wanted you to find out the truth about…us." His eyes flashed for a moment, and Kakashi's felt the Immobility Technique lift from his face.

Kakashi felt like an idiot saying the words, but he knew that they were true.

"You're a vampire."

There was that laugh again, positively dripping with poisoned joy.

"Glad you've caught on." Itachi placed a hand on each of Kakashi's shoulders and leaned him back into the tree, bringing their faces uncomfortably close. Itachi's pale, pale skin reminded Kakashi of his nightmare. "Yes. And as to your first question…why yes, I am going to kill you. But first…" He brought his lips to Kakashi's ear and whispered very quietly. "I'm going to make you wish you were dead."

"Stop it, Itachi."

Quite literally, Kakashi's heart stopped. It was only for a second, but it still made him bright spots pop up in front of his eyes. The world spun dizzily, making his breath catch in his throat. He had to be imagining that voice, even more familiar than Itachi's, and filled with even more stomach-clenching memories. He tried to turn his head towards the voice, but the Immobility was still working.

"He is not yours to kill. I thought we already agreed on this."

But no, it was him…it was really him…

Itachi let out his breath in a sharp hiss, bathing Kakashi's face in the bitter smell of dried blood.

"I know, but now that I finally have him…" Itachi's nails dug into Kakashi's shoulders painfully. So that's what all the scratch marks were on the victims bodies! "I do not want to let him escape."

"You know I won't let him escape, nii-san. I've done what you want. Now let me have the reward you promised me."

Kakashi heard an irritable moan and felt Itachi's weight lift off him, as well as the stiffness in his head. He looked up just as his new tormenter settled down in front of him.

"Hello, Kakashi-sensei." Sasuke gazed down with a twisted smirk on his face, his pointed incisors sparkling like daggers in the light of the full moon. "Happy Halloween."

A/N I do NOT own the term "Darker than Black". It was taken from the anime of that name, which btw, is an amazing show (one of my favorites). I just thought it fit the situation :)

TBC ASAP.
