Summary: Kuroba Kaito thought he was as normal as a magician phantom thief could be…until he gets an unexplainable urge to bite Edogawa Conan at a heist—literally. Vamp!Kaito, KaiShin

A/N: So…I finally decided to post something after…two years? Erm, yeah. This is rather sudden. To those who read my other fics and are actually waiting for updates, I assure you that I'm currently revising them, not abandoning them. I only ask you to be patient as I am also a college student trying hard to deal with majors all at the same time. Science may be interesting but it gets tiring after some time, you know?

As for this story…I've been itching to write a KaiShin fic in ages and…StargateNerd suggested something along the lines of Kaito being a vampire and having to drink Conan's blood. A scene came into my head the moment she suggested that. And, as usual, my mind decided to make everything mixed and messed up. So…there may be a few remote similarities to DNAngel and, possibly, a vague relation to Harry Potter fics. I would apologize for my imagination's eccentric quirks…but as annoying as it is, I'm proud of it :P

Let me warn you: some parts pertaining to the whole vampire thing may not be like what you know. I will tell you now that aside from a few fanfiction (mostly in HP), Hellsing is the only reference I have to vampire information.

And since I have no net access while writing this, I've no means to check facts and all…so everything will be made up. If you do not like what I my muse came up with, you're free to leave a review with a comment or suggestion.

…if this becomes longer than what I anticipated it to be, BLAME STARGATENERD! She gladly takes all the responsibility for whatever insanity may ensue in this fic. Right, SG-chan? XD –dodges bullet- HAH!

Moonlit Blood
Chapter One
By Milky Étoile

It was yet another successful heist for Kaitou KID. He had just managed to fool the KID task force into heading the opposite direction that he was going. And if they all happened to get caught in some form of trap… well, that was just a bonus, right?

As he ran towards his escape route, he idly wondered where Tantei-san was, seeing as he wasn't present for the whole day, or the past week at school.

Well, no matter. Tantei-kun was sure to be around. He was sure that the short detective was in the building, having spotted him earlier while looking around under his disguise.

He was startled out of his musings when an unexpected question came through the receiver he'd stolen from an officer earlier for the aforementioned disguise.

"KID. Are you sure what you have in your hands is the real Bloody Moonlight?"

He immediately recognized it to be Tantei-kun's. He was astonished enough to take out the jewel that was his target for the night. And, indeed, after a closer inspection, he realized as the detective implied that it was merely a good replica. Possibly partly made from the exact same gemstone Bloody Moonlight was constructed from: ruby.

"I'm sure you've realized by now," Tantei-kun spoke once more. His smug drawl infuriated KID for a moment. He had the gall to copy his intonation when taunting his adversaries!

He managed to find the correct frequency of the radio that the message came from in a matter of a minute. He responded in an obviously (to him anyway) controlled manner, "It seems that someone else decided to be a thief tonight, Tantei-kun."

His statement earned the desired effect as evident when his rival retorted in a gruff tone, "Don't put me in the same category as you, thief. It was done with the permission of the owner."

The phantom thief wondered how the detective gained permission but brushed off his query for now. "Well, then, Tantei-kun…will you tell me where you've hidden my target for tonight? You've managed to take me off my schedule for thirteen minutes and twenty-four seconds already." He swore to himself that he didn't sound frustrated.

Tantei-kun's reply clearly told him that he only tried in vain to lie to himself. "Who says I hid it?"

Kaitou KID's mind reeled with what could have possibly been done to the jewel. He was interrupted by that now-really-annoying voice of Edogawa Conan.

"Why don't you try to recall your escape plan for the night and see if the mouse can become the cat too?"

Once he processed what had been said, he hastily entered the room that he was to get out of through the window in time to see that the short detective was already past halfway of the string he had rigged earlier. It led to the next building that had a much higher rooftop than the current one. Apparently, the detective had been able to deduce how his hang glider depended on the air currents and would therefore need the higher altitude to ensure that he would not bump into anything unpleasant.

As he positioned himself to follow on the string, he raised an eyebrow at the open window. He was sure that he hadn't unlocked that earlier. His smirk returned then. Now he was sure that the detective could give him quite the run for his money if he wished to be put in the same category Kaitou KID was in.

"Are you sure you're meant to be a detective, Tantei-kun?" He was able to handle sliding through the string while speaking through the radio. "You're showing so many skills for my trade."

"Are you recruiting me, Kaitou KID?"

The thief looked ahead at that and was surprised to see Conan casually leaning on the windowsill with a pair of scissors held to the string…he immediately paled. Cursing his rival inwardly, he shifted his body weight to make himself move faster.

Unfortunately for him, he wasn't fast enough—Conan cut the taut string before he was five feet from the window. The string recoiled to the other end in what seemed to be slow motion for the thief. He gritted his teeth and nimbly jumped the distance. He couldn't make it to the targeted window but grabbed onto the ledge of the one below. Miraculously, his top hat did not fall from his head.

"Alele," a very young voice came from above. "You should be more careful, thief-san. We don't want you dying off-schedule, do we?"

It was Conan with what struck KID as a smirk similar to his own. It was enough to make him pull himself up and open the window he was in front of, picking the lock to do so (which, of course, wasn't hard at all). Not even bothering to look back up through the window, he ran up the flight of stairs nearby. He paused on the floor that Conan was in earlier to look to the window—which was now closed. He was stopped in mid-curse by the loud sound of footsteps somewhere above him. Recognizing the producer of the sound, he continued his way up the stairs—to the roof where he usually made his escape. He somehow found it ironic that it was him doing the chasing now. The mouse becoming the cat indeed. Tantei-kun surely knew how to be a challenge.

He was thrilled though. If this was how the detective felt every time he chased him, maybe he should let himself be "outwitted" more often then? Or maybe he should try to get their roles of thief and detective switched?

With a grin, he opened the door that led to the rooftop, almost expecting Conan to do the taunting for this heist. He did get bragging rights for outwitting the Kaitou KID, even for only some minutes.

But he was startled to hear a shout instead.

"DUCK, KID!"

Instinctively following the order, KID heard the clang of a bullet hitting a metal pole to his left. Eyes widening, he immediately turned his head towards the direction the projectile came from. Seeing no one in that corner, he looked further, past the ledge, and spotted a black-clad figure. He pointed his card-gun and pulled the trigger, not even considering that his target was on the next building's rooftop, more than ten meters away. The person ducked the precisely aimed card and managed to get away in haste.

KID didn't let his guard down as he put away his card gun and scanned the surrounding buildings for any other suspicious movement. Finding none, he looked around the rooftop he was on, remembering the one who had warned him in time. He quickly spotted the short silhouette beside a 4-feet high box that he assumed to be a generator. The phantom thief let out a gasp when the metallic scent of blood assaulted his senses.

"Sorry, KID," Conan muttered with a forced grin as he clutched his bleeding right arm tightly in a vain attempt to stop the flow. "Seems like I can't continue our game of cat and mouse tonight."

For a moment, the white-dressed thief stared, frozen by the somehow amplifying smell of the blood. He couldn't help but notice that it enticed something inside him, and his mind didn't even register that his policy of no one getting hurt was violated. Instead, his head was being flooded with the desire to—

KID fiercely shook his head in a vain attempt to clear it of the strange and inappropriate images that assaulted it. It wasn't good that he suddenly had the urge to… to bite Conan, possibly even maul him.

While he was having an internal battle, he didn't notice the detective stepping towards him in faint concern for the thief. He was astonished and almost jumped when Conan asked, "Are you okay, KID? You're not afraid of blood, are you?"

Taking a deep breath, the thief considered retorting that no, he wasn't afraid of blood but actually wanted it so much at the moment for some odd reason that he would bite someone to draw it from the person. He restrained himself though and replied in a neutral tone, "Shouldn't I be asking you that, Tantei-kun? You're bleeding." The urge to hit himself for his stupidity shortly overrode the urge to move closer to his rival.

Apparently, Conan agreed with his opinion concerning his own idiocy, as he was fixed with a deadpanned gaze. "Thanks for telling me, Mr. Obvious. I didn't even notice," he drawled. He shook his head and peered at him through his large glasses. "It's just a flesh wound, I'll manage."

KID cleared his throat. "Nonetheless, you need to be treated immediately." He idly wondered why the detective didn't even seemed concerned that he was losing a fair amount of blood, effectively reminding him that he still wished to have the boy's blood. Literally.

For a moment, neither of them was concerned with moving from their places. They were in the building next to where Kaitou KID had stolen the fake Bloody Moonlight—faintly reminding him of how the boy had actually outwitted him that night.

The thief was silent as he used every ounce of self-control that he had to prevent himself from harming Conan further. He managed to force himself to procure a whole first-aid kit from some pocket while ignoring the kid's piercing blue-eyed gaze. He approached Conan with a trepidation that he did not show.

"Perhaps you should let me repay your earlier assistance," he said with a smirk that he easily mustered at the sight of the detective slightly gaping at his first-aid kit, possibly in wonder of how he managed to bring such a box around. He made no comments about it however and only proceeded to do his self-appointed task. As he drew near Conan, he easily noticed the tensing of the younger male. He ignored that too—it was obvious that the other was anxious since they were still on the opposite sides of the law. He would feel the same way if their roles were really switched.

Unfortunately, even with idle musing, he could not help his eyes from darting towards Conan's wound. It was clear where it was as the boy kept a hand on his uncovered arm. He vaguely noted that Conan had enough sense to remove his usual jacket. His observations were not enough to quell the weird urge though—it worsened, enough that he'd had to pause for a moment as a shudder passed through his body in his effort to keep himself from attempting to drink the dripping blood…

He may not understand where the sudden urges came from and why they even existed, but he was pretty sure that even for a magician and phantom thief, they were not normal. And he instinctively knew that he might end up hurting someone if he let those urges get the better of him.

He was so deep into his thoughts that he didn't realize he'd been sitting in front of Conan already and staring morbidly at the slow but steady flow of red liquid from the other's arm. He reluctantly turned his gaze towards the detective's face when he heard a clearing of throat. He was expecting to see an amused or maybe irritated look upon that smaller face. He did not expect a curious one.

"I wasn't aware you held some fascination for blood," Conan remarked, not a trace of discomfort in his tone. If KID hadn't seen his injury, he'd have thought the boy was perfectly fine.

"I wasn't aware I had one," was his curt reply. KID fixed Conan with a stare for a moment, raising an eyebrow when the other's blue eyes had widened in surprise. The boy quickly recovered and presented him with his blank stare, making the thief wonder how his rival had gotten a poker face that was enough to match his. He forced himself to return to the task that he had delayed long enough.

Conan did not have any qualms about it and only stayed silent as he removed his small hand from over the wound. The sight of the injury was enough to distract KID from just the blood itself. The wound was about two centimeters long and was open. Conan's evaluation of his own injury was probably incorrect; it didn't seem like a mere flesh wound—unless it was an unusually large one. The gash was probably deep enough to cause so much bleeding but not too much that it would have reached any muscle or nerve. The high temperature of the bullet that made the wound would have helped in making it worse. It probably needed stitches.

He felt the detective's gaze on him when he finally moved to take off his white gloves that surely had traces of some chemicals that were utilized in his tricks. It wouldn't do to aggravate the wound by contamination.

However, when he turned back and knelt down to tend to Conan's wound with his supplies, he couldn't prevent himself from staring blatantly at the amount of blood that was flowing from it. An injury like that wasn't supposed to release that much, was it? Unfortunately for him, any concern he had was forgotten in lieu of that desire to just taste that red liquid became larger. He didn't even register the resigned sigh that the detective let out.

"If you didn't want to heal my wound, you should've just said so in the first place."

Kaito KID blinked out of his stupor at the statement that didn't even register in his mind.

"What?" If he weren't feeling so disoriented, he would've smacked himself for letting out such an unintelligent response.

A ghost of a smirk appeared on the other male's features. "If I didn't know how bewildered you must be feeling now, I'd be laughing at you. As it is, I only want to ask you one thing." Conan's expression became serious. "When was the last time you fed yourself?"

"Huh?" This time, thief almost did hit himself for that.

The detective shook his head, as if in exasperation. "Look, you don't have to hide what you are. It's obvious for me after encountering so much of your kind." He reached up with his non-injured arm to take off his faux glasses. He folded them and settled them on the front collar of his shirt.

Though sufficiently even more confused, KID felt coherent enough to ask, "What are you talking about, Tantei-kun?" He only barely managed to keep his voice straight.

Without the glasses, Conan's blue eyes were more piercing than ever. "As I said, you don't really have to pretend. Unlike most people who find out, I'm not really frightened in any way." He took out a handkerchief from his pocket and began to wipe away some of the blood that slid down his arm. The thief felt both disappointed for the wasted blood and stupid for not having thought to just use a clean handkerchief as a temporary bandage. He could've just avoided the whole debacle, though he somehow didn't wish to.

When it was apparent to the detective that KID was not going to respond, he sighed once more. "Really, I'm more intrigued that you, of all people would turn out to be a vampire. I suppose a few of your skills had to come from somewhere…"

Now, KID stared incredulously at him. He was a what?

Conan seemed to get more anxious as the seconds passed without the thief's response. "If you don't want to admit it, then fine. You're free to go on pretending that I don't know. I'm bound to not tell anyone who doesn't know anyway so you wouldn't have to worry about anyone else finding out you're a vampire. Who would believe me anyway?"

There was the word again. What in the name of Pandora was the detective talking about?

"I don't even know why I'm bothering," Conan muttered with a twitch of an eyebrow, signifying his growing irritation. "Regardless of your obstinacy, I should really offer to feed you. I don't even want to think what other poor creature you'd attack mindlessly when you're fully consumed by bloodlust."

Before KID was able to accuse the other of being out of his mind, Conan held up his wounded forearm to his face, effectively making him swallow the comment with the sudden barrage of the coppery scent. The detective seemed aware of the effect of his actions though as he let a smirk fully tug on his lips.

"So, instead of causing my conscience any grief for the negligence of your melic," his blue eyes seemed to reflect the light of the moon as he continued to look at the thief straight in his indigo orbs, "Why don't you just go ahead and bite me?"

To be continued…

Hm…only 2k words. Sorry though, I just couldn't resist cutting it here. Hopefully, the next chapter would be longer.

How was it? Too OOC? Horrible? Terrible? Good? Terrific? What? I didn't mean to make that interaction too long, I swear!

Thinking about it now, as much as I'm not a fan of Stephenie Meyer's work, I vaguely recall a similar remark somewhere in her second book. Not like that matters now…

As for why our dear Kaito doesn't seem to be aware and why our other dear Conan does instead, you shall know in the next chapter.

Or, at least, I think you will. You're all free to take a guess as to how I made the whole vampire thing work. I'll be giving out virtual cookies for those that figure anything out! Not you though, SG-chan. You get to have cheesecake, 'cause you were the one who gave me the prompt 8P

Reviewers get to have my special, homemade virtual fudge brownies.

Thanks for reading!
