He stumbled slightly as he appeared in his home, his shirt still partially falling off. Who in the world tackled someone and then bit them to show dominance? Apparently that prefect did because Hadrian had never met someone like him in all the other universes he had been to.

True Voldemort had an obsession with dominating the magical world and living forever, from personal experience it wasn't as great as it sounded, but for someone to bite a person? He was pretty sure that Voldemort didn't go biting his followers.

He mentally shivered at the thought.

Bringing a hand to rub the sore spot on his shoulder he scowled when he felt the indents of teeth. That would leave a mark, if he was a normal human, but since he was magical he could heal something like this easily.

He focused some magic on the hand on his shoulder and sighed in relief when the pain started to lessen little by little until it was completely gone. Let's see what the prefect would think about that.

Well at least the Canary would take a while to get here, from what he saw the small yellow bird of Hibari's was looking a little interested in him, that would teach him to not leave him to get molested by some teenager.

For now though he would rest.

"I'm going to rip your arm off and make you eat it."

Hadrian cracked his eye open sleepily and stared at the body glaring down at him, the golden eyes almost glowing with fury. "I don't know what you are talking about."

The child narrowed his eyes and leaned forward, his black hair falling from his shoulders and resting on Hadrian's cheeks. "You left me to deal with that bird; do you know how long it took until I could finally get rid of him? I had to transform into three different things until he gave up."

Hadrian smirked. "Really? I'm surprised he still persisted when you changed form."

"I was too." The child agreed sitting up crossing his arms, but not moving from his chest. "Apparently the bird didn't care if I was a cat, he still continued to follow me around."

He chuckled when the child frowned, more like pouted, in irritation. "Maa, that's what you get for leaving me to literally get bitten."

The child scoffed and turned his head to the side.

Over the years that he had traveled different worlds he found that as his magic grew in power so did the Canary, at first he had been able to pull off small things like butterfly's and such. But eventually he was able to turn into other animals, though the largest he could pull off was a wolf, it was then though that his companion pulled off something they both were shocked about.

He turned into a child looking to be around the age of seven and so far he had only aged one or two years before he stopped and just remained to look like a nine year old.

Obviously people would get curious about why a nine year old boy was following around a man and wasn't going to school, so his companion only changed into his human form when no one else was around.

They both were unsure as to why he could do it the first place, but it was actually handy so they just accepted it.

"Say…" Hadrian spoke up breaking from his thoughts. "What time is it anyway?"

"You slept for a whole day."

"Really?" Hadrian blinked. "That's means I missed school huh… well it isn't like I need to go to it anymore since I have the information I want."

"Ciaossu."

Hadrian jumped in shock and the child fell off his lap and onto the ground, a startled yelp coming from him.

The black haired man, who had shifted back to his normal form, turned his head toward where the voice was and spotted Reborn standing a few feet away from the couch he way laying on.

"Maa," Hadrian sighed, sitting up. "You scared me."

Reborn gave him a blank look before turning his gaze on the child. "Who is that?"

"Ah…." He thought for a moment, before realizing he hadn't named the child. Which was actually kind of sad, but it never actually came to his mind. "That is….Nao." He replied picking a name out of random.

The newly named Nao sat up and gave him a glare. "What-?"

"I see." Reborn said, peering at Nao curiously for a moment before focusing his attention on Hadrian. "As a member of the Vongola I have a mission for you."

Wow, that was quick.

"I want you to go with Dino Cavallone and help him train his student."

"Maa, can't he do something like that by himself?"

"Yes, but you can help his student with increasing his speed." Reborn replied. "You're speed is superior to Dino's, I've seen it."

Hadrian hummed thoughtfully. It wasn't like he had anything to do anyway, and really he didn't want to go to school. So he guessed he could tag along, thought he didn't really want to train some kid in the 'art of speed' it didn't sound that bad.

Besides what's the worst that could happen?

For some reason though, Cavallone sounded familiar.

{Men in boxers}

Hadrian felt like he had been played, and stupid, he most definitely felt stupid. Why didn't he ask Reborn the details? He had no clue, but it was too late now.

He could say though, that Hibari's speed was rising.

He broke out of his thoughts just in time to swerve around another bamboo tree, hearing the cracks of the ones getting knocked down by the destructive prefect. He was barley having any trouble since he was use to running after all the years he spent getting away from dangerous things, Hibari though was having some difficulty, especially after five hours of chasing him.

The prefect seemed to be determined to get to him, especially when he saw that his bite mark was gone.

Hadrian still shivered whenever he thought about the reaction, Hibari's face and darkened and his eyes flashing before a wide smirk had formed on his face and he had instantly started to run after him.

He felt bad for Dino though; the blonde was getting completely ignored by his student and had given up long ago on trying to get the tonfa wielders attention.

As for Nao, he was currently in his canary form and was hiding somewhere in the forest, refusing to admit he was hiding from Hibari's canary Hibird.

He yelped when a bamboo tree fell inches from his body and turned to head the other direction only to skid to a halt when he saw Hibari waiting for him a few yards off.

The prefect really was like a predator, he had thrown his tonfa at the tree that had fallen a few moments ago to purposely make him turn the other direction.

Hadrian paused giving the prefect a wary look before scanning his surroundings, it seemed he had gone deeper into the forest then he thought, he couldn't even hear Dino.

He snapped his head forward when he heard the prefect advance, and stepped backward a few paces, eyeing the smirk suspiciously.

They continued their little game until a suspiciously placed branch made him trip, at the moment that he started to fall backwards Hibari struck and he was once again under the prefect, but this time on his back.

Hadrian winced and gave the other teen a bland look. "Maa… how's it going?"

Dark eyes narrowed and Hibari bent from where he was straddling his waist, placing his hands on either side of his head. "Where is it?"

"Where is what?"

Hibari glared. "My mark, where is my mark?"

"Saa..." Hadrian replied. "I heal faster than most people."

"That is unacceptable."

He shifted. "How about you tell me why you 'marked' me in the first place."

A smirk formed on the other teen's features. "Because you're mine."

"Hah?" Hadrian exclaimed, sending him an odd look. "What in the world makes you think that?"

"The older cow herbivore said so."

"Cow Herbivore?" Perhaps Hibari was crazy. "You talk to cows?"

He received a hit on the head via tonfa. "No."

He sighed and rubbed his head. "Maa… whatever you say…" He replied and turned his head away to look for Dino. "Where is that man?"

He jolted when the prefect shifted down and stilled when a warm breath fell on the side of his neck. "I'll just have to mark you again so the other Herbivores know not to touch you."

The sharp teeth digging into his neck made him wince and he immediately started to push at the chest above him, hating how he had gotten into this situation in the first place and how his teenage form really did nothing to stop the action.

Once again Hibari unlatched from his neck and stared at his neck as his magic instantly healed it.

"I see…" The prefect growled and bit down again, harsher this time.

Hadrian winced again and tugged at the prefect's dark hair in attempt to get him off. "That's not going to work."

He was ignored and could only lie helplessly as he was continuously bitten.

The clanging of two weapons echoed down across the clearing as Hadrian watched them spar, this time instead of a forest they were by a canyon, the environment different from the bamboo forests.

The prefect had finally focused on fighting Dino, but it was safe to say that his neck was sore even if the marks were healed.

Hibari wasn't very happy when he realized his mark wouldn't stay no matter how many times he tried, but Hadrian had a feeling that the prefect wasn't about to give up.

Two balls of feathers made him jump and stumble back as they flew chaotically around him, he took another step back in an attempt to get away and found himself falling into the nearby stream.

Dino and Hibari paused in their spar and glanced toward his soaked form.

"Are you okay Sotaru?" Dino asked.

He pushed his hair from his face and nodded, pushing himself up. "Yes I just-ah!" His foot slipped on a rock and he would have fallen face first into the water if he hadn't propped his body up by his arms.

Dino chuckled and walked over. "Here let me."

Hadrian got on his knees and sent him a thankful smile. "Thank-"

Only for Dino to slip and make them both fall back into the water. He groaned and sent the blonde a bland look. "Thanks."

Dino laughed sheepishly. "Sorry, Romario just left a second ago."

"Green-eyes." He tilted his head up and gave the Prefect a curious look.

A hand suddenly grabbed him by the collar and he was hauled to dry ground and set back down. "Thank you Mr. Prefect." He murmured rising to a standing position.

Hibari nodded and got into a fighting position. "Fight me."

Hadrian sighed before nodding and transforming the elder wand into its staff form. "Very well." He should have known that the prefect wanted something.

"Hey!" Dino called as they started to fight. "What about me?"

They unfortunately didn't hear the blonde, Hibari may have but he didn't care, and continued to fight leaving Dino to attempt to get out by himself.

Poor Dino though, since Romario was taking a walk somewhere he was stuck with crawling out of the stream since he was too clumsy to walk out of it.

The blonde started when the two canaries flew past him, watching curiously as they made an odd sort of dance as the lighter one followed the darker one without any sign of relenting.

{Men in Boxers}

Reborn smirked as he read the report that Dino had sent him, it looked like his plan had worked, the two potentially strongest members of Tsuna's family were getting along.

After Lambo had let it slip that Hibari did indeed have someone he was interested in ten years later, Reborn made it his goal to find that person.

Though he had no qualms that the prefect would be tamed, from the looks of it he seemed to get more wild if anything when around Hadrian, he couldn't help but wonder if the newest member of the Vongola had it in him to keep Hibari's interest on him. That would make it so Hibari wouldn't have a reason to stay around the Vongola.

But perhaps not, he mused, Hadrian didn't look like he was one to settle in one place for a while either, so he could only guess as to what would happen.

He was interested though, in how they would interact with each other, and would have to observe them from afar.

Reborn could already tell that it would be amusing.

AN: I hope you liked the chapter, and really I can't wait until I get to write when everyone is in the TLY universe. Because poor Hadrian is going to have a lot more trouble with the TLY!Hibari then he already is with the present one. I'll see you next chapter!
