Title: A Demonic Sky

By: Metamorcy

Pairing: R27 and 27R

Summary:AU, I must have been out of my mind to make a contract with a demon, Reborn thought as he stared at the creature across him, Really Stupid. And it just has to be one that enjoys messing with him.

Disclaimer: Seriously? Don't own, just the idea

A/N: Just to make sure, Giotto is Vongola Decimo, not Primo. Stella is Vongola Primo

"So you've decided…"

"Yeah, sorry. But I want to do this, I think I'm the only one that is willing to do this." Tsuna smiled softly, turning away from the person behind him, the atmosphere around him darkened, probably because he knew that this was a memory, a memory he hadn't had for a long time.

"You'll never be accepted back up here, you'll never regain your current post, you'll become everything we hate."

"Don't say that, that's not true. I can still be myself despite the change. I will protect the people I care about my own way. But sadly, no one agrees with my wishes or my point of view, that's why I want to leave. I feel too restricted here, too demanded and held down, I want to be free and do what I want to protect everyone I care about my own way without having to follow some stupid rules."

The person behind chuckled, stepping closer. Tsuna could hear the fluttering of wings and could feel the warmth of the sun despite seeing only darkness. "There's just no getting to you. But that's fine, you've always been like that. It's something I've always admire about you. Now, please don't go tripping somewhere and getting yourself killed."

"H-Hey! I don't trip anymore!"

"Yes, you do and you still do. And you're also stuttering."

"That's because you're making me!"

Reborn twitched, rolling over in bed when he suddenly felt the fingers gripping onto his shirt suddenly tighten around his chest, digging into his cloth and then into his skin. Luckily, it wasn't hard enough to tear into him, but regardless, the pressure made him awaken momentarily by habit and peered down to look at a sleeping Tsuna, whose eyebrows were narrowed as if dreaming. The brunet was wrapped tightly around him as if he was a pillow, looking like he was going to start muttering things at any moment, and twitched for a second in frustration. Those fingers loosened temporarily before tightening up again, Tsuna letting out a small grunt and drew his body closer for warmth.

'Must be dreaming…' The hunter gave a small grumble when he felt those arms tightening some more around him, the pressure almost getting to the unbearable stage. Rolling around so he could face the demon easier, he peered down at the sleeping expression, pushing back a few strands of hair to get a better look, and cupped a cheek gently. His touch, his fingers moving over the soft fleshly skin, made Tsuna twitch, nudging closer to him like a cat, almost looking like he was about to purr.

Reborn couldn't help but chuckle in amusement, able to see that demonic tail underneath the covers moving around, and yet even with his touches, Tsuna didn't wake up. He let his fingers map out those soft cheeks, the young face that had some baby fat in it, and those soft silk-like strands of hair. Ah, the hair, it was wonderful, soft like feathers, and that scent of shampoo was still fresh from that night, almost making his nose twitch. Shifting around, his fingers went to the back and made some circling movements along the spinal cord and almost immediately, the demon began to relax at his touches, the strength of his grip weakening. The incubus arched his back to move closer, one knee rising up in-between Reborn's, and that tail eventually slipped over, wrapping around the hunter's waist.

"Tsuna…" Reborn muttered, still continuing the movements on the back until he saw those soft honey-colored eyes opening up to peer at him curiously. The human couldn't read the emotions in the eyes, it was too fleeting, too quick, and then there was realization as the brunet found out that he was no longer dreaming and was now in reality. Tsuna blinked for a few moments before nudging closer, hoping to act like nothing happened, but Reborn noticed. He had been around the other long enough to figure out certain actions, not all, but some and this was one of them. "Were you having a nightmare?"

"More like a very old memory," The brunet admitted softly, peering up into Reborn's black eyes, and didn't remove himself away, the warmth shared between the two bodies comfortable. "It's been a while since I've remembered it."

The hunter hummed to himself, not bothering to push himself aside, knowing that the rest of the world was fast asleep except for a few Vongola members that were wandering the hallways either to clean up some things or for protection. He could hear the footsteps going up and down the pathways, but he ignored them as long as those sounds kept moving and didn't stop in front of his door. "Since you said it's an old memory, that reminds me, just how old are you?"

Tsuna chuckled at that, closing his eyes like he was about to go to sleep. "That, I won't say. Just think I'm extremely old and go with that. You wouldn't believe me even if I told you."

"That doesn't answer much."

"Of course not."

"Another question."

Tsuna opened his eyes momentarily, deciding to go along with Reborn's persistence. "Hmm?"

"You used a similar skill to Giotto's, the flames on the hands, I recognized it right away," Reborn lifted up a hand to push a few of his black-colored bangs aside to see better, stopping at his curl to twist it around his finger. "It's a unique skill only he has that's been transferred through his side of the bloodline only. It was used by a previous head of Vongola, the Primo, who is his great, great, great grandfather. I've had some suspicions with you. Why are you able to use something like that? And I saw you gazing at the portrait of Primo with a smile, you can't hide that from me."

Tsuna chuckled at that, Reborn was sharp, he had to give the human that. "I guess I could answer that, shouldn't hurt, but this information remains between us, got it?" The hunter gave a nod in agreement, like hell he was going to tell anyone, it just meant he was the better informed about the truth of matters. "The truth is that I met Stella Cielo, or Vongola Primo, as everyone calls him nowadays, a long time ago. He was merely a child at that time and his father, a demon, used to be a friend of mine. When he heard that he had gotten into some trouble, I went to help, however...I was far too late."

Blood…Organs…Tsuna peered up and could see broken and torn flesh of a woman hanging off the walls, a face twisted in fear and agony.

"Because he had no family relative, he was placed into an orphanage and I would visit him now and then to keep him company since at that time, I had nothing better to do. Trust me, when you get as old as me, anything that can keep you occupied for a good number of years is better than nothing. Anyway, he was half-demon so that heritage was still there, uncontrolled, and I ended up teaching him that skill to help control those flames of his. Eventually, he created Vongola, a group of people that worked along with demons to help protect the humans of this world, and I became one of those demons that helped along. Stella eventually got his hands on the Vongola rings and officially declared the name of his group to the rest of the world. We got along quite well back then, everything was much more peaceful, demons were more friendly and coexisted to an extent with the humans, but that slowly changed when it went into Secondo's hands, who was Primo's cousin on the human mother's side."

"That human didn't like demons, no, he hated them, despised them. And we demons ran away and went into hiding. Secondo believed that all demons were evil, even the good ones like the fairies that helped the humans. He wanted us all dead and Vongola followed along, killing off all those around. I too vanished. Luckily, the only person that I taught some of my skills was Primo and he never passed it on to someone else, always saying he could never find anyone worth it. Sadly, Primo's views became conflicted with Secondo's and he was to be executed for being a supposed traitor to mankind. Myself and a couple other demons helped him escape from Vongola in Italy to Japan. It wasn't a great time after Primo's reign ended."

Reborn remained quiet, listening carefully. He hadn't known about that, about the history of Vongola besides the basics, it hadn't been worth the effort to find out. "I remembered reading that Giotto is a descendent from Primo that came from Japan, I take it would be unsurprising if he passed the skills he knew along the way. Giotto is the only one that can use flames like that, unlike the other Vongola bosses who either didn't have them or were so weakened that they needed extra port to convert them."

"That's correct. Later, I visited Stella about fifty years later to see his child using the same abilities, the flames he was bearing was pure and untainted, but I didn't interfere and left soon after."

Reborn pulled away from the brunet to stare up at the ceiling and sighed, placing an arm over his head in frustration. That was far too much information to take in, stuff that was probably buried deep within the books of Vongola's true history - if they haven't been burned yet. To think the incubus had been around that time, just how much information did Tsuna hold in his memories?

He turned to the brunet curiously, searching within those eyes for anything else, and sighed again, recognizing that look on that soft face from other humans. Tsuna wasn't going to say anything else, he was dwelling in memories that were too old and unwanted, memories that brought back things that he didn't want to remember anymore. Was that the issue with immortals? For demons that had been living for far too long, they knew things that normal humans would never understand or remember over the course of history, things that may have been diluted by false writing or have simply become forgotten.

Reborn felt Tsuna nudge back against him and smelled that wonderful alluring scent, that strawberry aura that made him want to do things with the demon, but resisted. He wouldn't allow his desires to take over, not after today, and huffed, closing his eyes, wanting to head back to sleep.

It was going to be a long day tomorrow. He could already tell that Giotto was suspicious about Tsuna's true identity and his capabilities. What a pain.

"I see you two are looking better in spirits today." Giotto chuckled, watching as Reborn and Tsuna stepped into the dining room for breakfast. The room was much smaller compared to the ballroom with a table containing a max of fifty chairs. The Vongola Decimo and his guardians were at the front, just barely receiving their breakfast from the cooks. There were some other hunters in the room, but very few in number compared to yesterday, many looking angry at finding out the mission was now complete and over and it was all because of Reborn and his companion. There were some jealously-filled stares towards the two and some that were staring at Tsuna as if he was a bag of meat. The demon simply upturned his head at them, completely disregarding the latter.

The two contracted companions didn't say much and settled into the chairs, slightly away from everyone else, and ate their breakfast quietly. Tsuna not so much since he didn't require human food, but tried regardless to keep the attention off of him, cutting into his eggs to make them easier to stuff down his throat. Eventually, when no one was looking, he nudged his food over to Reborn, who quickly devoured it from hunger.

As everyone started to finish up their breakfast, they remained quiet, and turned to the front to hear about the end results of this mission.

"Now then, let's get onto topic. Those armored demons, Rustengans, as you called them," Giotto turned to Tsuna to get a nod of confirmation. "We've never seen these sort of demons before, much less find anything about them in our books."

"That's because they are not armored demons," Tsuna interrupted, arms folded against his chest in frustration. "They are mist demons that took possession of the armor that was hanging around. However, there shouldn't be that many around and I think the bigger question is why there were so many anti-magic armors down there in the first place."

Alaude decided to step in, placing down some papers that everyone suspected to be reports. The documents were lined with layers of words and some had pictures attached, clipped on at the top. "My group and I investigated the rooms and the armor thoroughly. However, we've managed to come to a conclusion that someone had placed them there, purposefully I'm afraid, and even used a device to attract the demons to Vongola. The secret passage way had been opened numerous times in one area where it happens to lead outside, allowing access for someone to come in and out without anyone seeing. This also allowed the demons to come in without notice. Also, the armors came from the weaponry room and they had been snuck inside, very slowly over a period of time and was unnoticed by the guards. Not only that, the barriers that were supposed to stop demons from coming in suddenly stopped sometime during the day, allowing a large number of them to infiltrate into the manor. Luckily, there were no causalities in the process."

"From what we managed to gather," Giotto cut in to speak. "The demons were somewhat forced to come here, without a choice as well. In this battlefield, we humans are currently in the wrong since the demons weren't coming here for a fight." His voice echoed within the room, many people sighing at that, and others agreeing. Tsuna seemed to perk up at that slightly, a little surprised to hear those words, and turned to Reborn for a moment. Had the humans really claimed they were in the wrong? "However, in trying to find the culprit that did such a thing, we have ended up empty-handed. We were unable to find the person that could move such a large amount of armors, enough to start a war with Vongola within. It is far too obvious that all of this had been planned out carefully until this day. We were just lucky that Reborn and his companion had been quick enough to figure out what was happening and stop the plan before it began too late."

Reborn decided to jump in, tilting his fedora downward slightly, and folded his arms. "That means you have a traitor within Vongola."

A silence settled in the room and the group looked among each other, hoping that the traitor wasn't in the room, listening to them. Giotto sighed, shoulders slumping downward almost in defeat. He had hoped that that wasn't true, but then again, it wasn't unusual. He could only hope that this traitor would remain quiet and not raise any more problems in the future though his intuition made him doubted that. The blonde just hoped that it wasn't any of his closest friends.

"Reborn, Tsuna, you have my thanks," Giotto smiled gently, shaking both people's hands firmly without any hesitation. The rest of the group was off on their own, talking to other hunters or among each other. "You really helped us solve this case. Though we weren't able to find the traitor, I appreciate what you've done for Vongola. As per agreement, I can give you the reward, both the money and the book. G, please give it to them."

The redhead, pink, Reborn would continue to argue, came close, holding the tome up to hand over. Tsuna, of course, was the one to receive it, carrying the old dust-covered book in his hands with alacrity. The appearance of the tome looked like some of those school textbooks, but this one only had around a hundred pages with a black hardcover written in demonic language, parts of it torn apart from age. The brunet read over the front cover and then flipped it open, blowing a breath to get some of the dust that had gotten inside to fly away. His eyes stared reading over the words quickly on the cracked yellow pages, barely listening to the conversation that was going on in the background, and chuckled to himself in amusement. 'Well, what do you know…'

"What is it, Tsuna?" Reborn questioned when he heard that snicker, an eyebrow raised in question. "Did you find something interesting in the tome?"

"Something like that," The brunet closed the book and tugged at the hunter, leaning up to whisper into the ear so no one else could hear. "I'll let you know in the car."

The human huffed, shaking his head, and pulled away, turning his attention back to his boss. He was interested in what Tsuna had been reading, it wasn't often he got to find out directly what was inside a tome without it being by the word of the mouth. His curiosity of what could be inside was starting to get him a little on edge. "Since everything seems to be done and over with, I'll be taking my leave. Just transfer half the amount to the usual account, I don't need all that money when I'm already earning enough from other missions. Use that money for the victims' families, they'll probably be needing it more than I do."

Giotto wanted to argue back, but Reborn didn't give the blonde a chance to speak when he started making his way out, Tsuna following right behind, still carrying the book in his hands. No one spoke after that, the doors closing right behind, and the two companions found themselves in the car, driving off back home. It was quiet as they drove around the Vongola's confines before getting out the gates to head into the paved roads that would bring them back to a city.

After a few moments, Reborn finally spoke up, questioning what Tsuna had meant before in the room. The brunet simply smirked, reopening the book, and positioned it comfortably on his lap. "It's a magic tome, it's been a while since I've seen one though," He flipped through a few pages quickly, glancing in-between, and went to the back. "Funny that I know who wrote this, but the demon is dead so it doesn't matter anymore, and I already know the magic within it, but it should be helpful to you. Anyway, it's a book for ice magic, its like a beginner's book."

"Beginner's?" Reborn questioned, he didn't know much on magic and had learned the current spells he knew through someone else, a previous trainer he had, but it had only lasted so long before the magic user died to old age.

"To sum things up, their just basic and easy spells you humans can work with. Anything higher than that can really harm their bodies unless they had some training. Tell me, what magic do you know about?"

The hunter seemed hesitant to let the other know, but gave in. "I know fire and wind spells mostly."

"Alright, then I'll help you with this. I can translate the meanings to you so you know how to use it. Knowing your skills and quick adaptation abilities, you'll learn the ice spells pretty fast while anything higher up, you'll just need your body to adjust to the spell drainage it can cause on you," Reborn nodded to that, following along as he continued driving down the street, watching out for other cars along the way. Tsuna hummed to himself, flipping through random pages. "And since you have time before your next mission, we'll take that time for you to learn these and you can try them out on the next demon you fight against. It's easier to figure out which ones to use during a combat since each spell reacts differently on the setting."

Reborn smirked, glancing over the demon for a moment, and then nodded. Though he didn't appreciate becoming a student again, much less learning from a demon, he doubted it would be so bad. It would just mean he would become more powerful than before. 'Well, I'm never too old to learn some new tricks. Maybe I can use these spells against Colonello the next time I met him,' Smirking, he turned the wheel to go right, heading onto the highway. 'Oh, yes, that sounds like a great idea.'

There's a lot of information that needs to be gone over in this entire story. I'm trying to introduce it to you softly so that no one is overwhelmed. Please note that arcs are generally 5-8 chapters long while smaller missions will mainly be around 1-2 chapters.
