Vampire Tsuna~!

Reborn had to stare at the red on his hands in disbelief and no little shock.

Anemia his ass...how the hell did that incompetent idiot Iemitsu miss that his wife was a vampire?!

He looked at the unconscious form of his new student. Tsuna had caught him off guard when he suddenly lunged at him like that... he had been too surprised to stop the brat from drinking his blood.

Reborn carefully managed to get the kid back into the house, and then started a proper investigation. For the most part his file claimed he was a clumsy, lackluster student. Likely from the seal Timoteo had placed on him when he was five.

He was expecting a difficult student, especially since the kid was raised civilian after years of bullying.

It took him five minutes to find the fridge full of blood bags, all of them close to expiration. He found several other clues of the fact his student was a full vampire.

Clues Iemitsu should have noticed as well...then again he had heard that Lal tended to handle most of the supernatural agents, so there was a chance he had no idea it existed. Though if that was the case then he was a bigger idiot than Reborn had always believed him to be.

It wasn't until close to dinner that Tsuna finally woke up, which made Reborn frown. He had never heard of a vampire to crash that hard after a feeding.

Tsuna stared at him with wide, unhappy eyes.

"What did you do that for? Do you have any idea how hard it is to keep my other half in check on a good day?" he asked upset.

"I was trying to bring out your Dying Will. What I want to know is why the hell you went straight for my blood rather than your last regret. And vampire or not, there is no reason for you to have slept this long after a feeding," said Reborn flatly.

On the plus side with the influx of fresh blood the seal was basically toast. He could feel Tsuna's flames from where he was unfettered... Timoteo clearly hadn't picked up on the fact Nana was a vampire either if he only used enough flame to contain human energies.

Tsuna squirmed a bit under his gaze.

"I don't drink fresh. I never have," he admitted.

Reborn stared at him.

"Are you telling me this was the first time you've properly feed from a live human?" he asked incredulous.

Tsuna couldn't look him in the eye.

Reborn could not believe this.

"Tsuna, do you have a hunting ground, or designated hunting spot?"

"Mama couldn't get one when her husband made her move here. Since she's only been here for less than twenty years I've had to make due with blood bags," said Tsuna tonelessly. "All the grounds have established claims long before I was even born."

Reborn cursed Iemitsu under his breath. Tsuna's claim had some validity to it...he knew that certain clans tended to stake permanent claim in human cities and made it difficult for newcomers to get any spots for several decades at least.

And Namimori was an established grounds...he knew for a fact that Fon's clan policed the supernatural side of things in the area.

"Does your stomach ache as if it's constantly hungry, even when you've eaten your fill? The blood bags barely sate it, especially the older they are, right?" said Reborn tiredly, rubbing his face.

Tsuna looked at him in shock.

"How do you know that?" he asked.

"Tsuna... it's not the actual blood that fills a vampire. It's just the medium. Blood acts as a conduit for the life force within it. When a vampire feeds from a human, he's absorbing a small part of the human's life force. Not enough to do damage...so long as you don't drain too much of it the human can recover within a few days. Almost like donating it really," said Reborn exasperated. "Frankly I'm amazed you've managed to keep from going into a complete blood rage if you've never properly fed before. Blood bags are only supposed to be a temporary measure at best."

"I'm sorry," blurted Tsuna. "I didn't mean to feed from you! It's just all my instincts went haywire after you hit me with that bullet and I couldn't control myself!"

"Considering you've never fed before, it's fine. You managed to hold yourself back from doing any actual damage. Though this definitely complicates things for a bit..."

He was going to have to insure Tsuna had a blood donor that he could feed from directly. On the plus side at least he didn't have to feel any guilt about dragging a civilian into the mafia.

Vampires tended to thrive in leadership positions.

Tsuna was still mortified.

Tsuna managed to hide his eyes from the rest of the class. He knew that vampires tended to show their true selves after a proper feeding. He never had to worry about it before though.

For the next few days he made do with his usual blood bags...but after feeding from Reborn he found it falling far flat. It was only the fact he couldn't hunt properly that kept him from getting more of it.

However less than a week after Reborn showed up, another Italian appeared. Oddly, he had a Japanese name. Was he a half-blood?

That confusion turned to understanding when Hayato started barking about becoming tenth.

Tsuna rolled his eyes.

"I'm calling bullshit."

Hayato paused and looked at him oddly.

"Excuse me?"

"It's obvious Reborn called you here, likely for more than one reason. Besides, if you really were eligible for the position it's far more likely you would have been dragged in to the main house before now, rather than send Reborn all the way from Europe to Japan to train a civilian," said Tsuna crossing his arms annoyed. "So please, can we dispense with the whole production and get to the point already?"

Reborn had to frown at that. He wasn't expecting this much sass from the boy.

Hayato tried to keep with the whole charade, but the second Tsuna actually moved far too fast for any human to possibly accomplish, he understood what the kid had meant when he said Reborn had called him in for more than one reason.

"You're a vampire?!" said Hayato in shock, dropping one of his bombs by accident.

Tsuna was a whirlwind as he put out all the fuses before Hayato blew his fool self up with his own weapon.

"Reborn, what's the real reason you called him here?" asked Tsuna to the hidden figure nearby.

Reborn came out of hiding... it was pointless to hide from a vampire. He likely heard Reborn's heartbeat or something, never mind Vongola Hyper Intuition.

"Since it's impossible for you to gain a spot in the established feeding grounds, I found you a donor. The fact he also has several qualities that would make him valuable as a Right Hand was bonus."

Storms were a dime a dozen but people with the knack for the job as a Right Hand, especially for the Vongola, that was was another story.

"If I had known you wanted a donor, I wouldn't have come. No one would want my blood," blurted Hayato.

Reborn looked at Hayato sharply.

He was quite surprised when Hayato let a pair of ears out that were the same silver color as his hair, and a tail that was distinctly wolf-like.

"I'm a half-breed. No vampire would want to feed from me," he explained.

"Actually I know for a fact that several packs in town donate to keep the vampire factions from causing problems. It's part of the agreement they made with the Hibari decades ago when it became available," said Tsuna. "There's also a few who act as blood donors to their vampire lovers. So long as it's consensual the Hibari don't get involved."

Hayato looked incredulous.

"You have no problem with feeding from me?" he said in disbelief. No one wanted a half-breed like him.

"I'm at the lowest rung of the pecking order in town. Only a select few even know I'm a vampire at all because I've been feeding only from blood bags for years. There's no way I could get into any of the hunting grounds and hunting outside the permitted ones would result in a short, painful end very quickly for me," said Tsuna. "So really, the 'disgrace' of feeding from a half-wolf wouldn't affect me in the slightest either way."

Tsuna could see hope spark in Hayato's eyes.

"Besides...it's not that unusual for a vampire to keep a wolf for a bodyguard, even if half the legends humans make up about us are full of shit," said Tsuna with amusement.

"Tenth! I'll follow you forever!" said Hayato with fervor.

Tsuna gently yanked on his ear.

"None of that. I'm not confirmed yet, and I would rather have a trusted friend guarding me than a rabid follower who doesn't listen to what I have to say," said Tsuna firmly.

Hayato whined a bit, but accepted the reprimand. It was far gentler than any he had before.

It took little time to get him settled into the Sawada household. Nana didn't even ask why he was there...she just accepted him without question.

Hayato did his best not to flinch when Tsuna fed directly from his wrist.

There was a sort of warm aura about him that grew stronger after he finished. His eyes glowed a bloody red that was hued with an amber orange, and there was power behind his gaze.

Tsuna might be weak now...but once his body adjusted to properly getting the right nutrients, Hayato had no doubts that the tiny teen in front of him would topple entire continents.

He wasn't expecting Tsuna to cuddle against him though. He was almost nuzzling the side of Hayato's neck, though without any hint of fangs present. It was...nice. Almost like Tsuna was scent marking him.

A few days later...

"Hey cutie...wanna be my donor?" asked one of the female vampires in the school. She flashed a bit of leg and it was clear she what else she was offering in exchange for a bit of blood.

Hayato scoffed. He had seen her type before, and the second they found out he was a half-breed they often changed their turn far too quickly. Or they treated him as disposable.

"No thanks. I already have a blood partner," said Hayato loudly enough for the entire class to hear.

Dead silence.

"Don't be ridiculous. How could you have found a partner so fast and not have it known?" she replied. "There's no need to play hard to get, you know."

She adjusted the skirt a bit to show some more leg.

It was then that Tsuna walked in and saw the display. He had been using the bathroom, so he had no idea what was going on.

However the scent in the air said volumes, and he grew pissed.

One moment the girl was trying to entice Hayato to act as her blood partner...the next she found herself struggling to breath as Tsuna had his hand gripped very tightly around her neck in a death hold.

"Keep your fangs to yourself, Saeko. He's mine," snarled Tsuna, eyes glowing red. "Unless you want to take it up with Hibari-sempai over a claimed partner."

Dead silence as shock descended in the room. Most of those in there were of the supernatural sect, as they had different lunch schedules from the humans. Mostly to avoid any issues from those who couldn't handle their unusual diets.

Tsuna usually skipped lunch, so most just considered him 'aware, but not involved'.

Finding out he was a vampire was a great shock to many.

"Boss, I can handle this," said Hayato.

"Hayato, show her your wrist," said Tsuna calmly, not letting the girl go.

Hayato looked confused, but undid the bracelet he had put around the bite marks Tsuna had inflicted. Tsuna had mostly healed them up, but he had left an indentation that was clear to everyone.

He was starting to figure out there was a reason for that.

Saeko went pale at the sight of it...or from the lack of air.

The silence in the class grew oppressive as the revelation Hayato had been claimed by Tsuna of all people sunk in. It didn't take much for the news to spread of Tsuna's status or the fact Hayato had bonded with him to filter through the school rumor mill.

Hibari called them in briefly to confirm the claim and that it was consensual before ignoring it.

Reborn was very pleased by the display. Clearly his new student had more of a backbone than he had been told. It was just that he had developed a general level of apathy to deal with the cards life had dealt him before now.

There was a silver haired puppy in the living room. Closer inspection revealed it to be a young wolf, rather than a domestic hound.

Tsuna grinned as he gently whistled, and the puppy cautiously went to his lap. It soon turned into a veritable puddle of goo as Tsuna attacked his ears. The tail went absolutely nuts when Tsuna brought out a brush and started to groom the pup's fur, getting out all sorts of knots.

Reborn snorted at the sight. On the plus side, Tsuna had definitely secured Hayato's loyalty, and his devotion to the vampire was only growing every day that passed.

It wouldn't take much for it to tip over into a full Harmony bond, once Hayato went active.

Reborn had to nod in approval at the food Nana placed in front of Hayato without a word. There was a lot of iron and protein rich foods to help with any potential bloodloss. Clearly she had been raised among vampires who knew the right way to care for a blood partner.

Hayato still couldn't believe how quickly they had arranged Tsuna's room so that he had his own bed and personal space without actually doing more than switching the single to a bunk bed and a second desk.

Not that he used the second bed. Tsuna was apparently very much a cuddler, and he had a weird habit of sneaking into Hayato's bed at night while half asleep. He had woken up more than once with the tiny teen curled up against him without a second thought.
