A/N: Timeline is going to be skewed, but this is an AU, so there isn't much to complain about. Onto the story!

Reborn found himself sitting beside Nova on the top of Tsuna's school his second day in Namimori. The eighteen year old witch had suddenly appeared and grabbed him before taking them to the roof in a swirling mass of color. For some reason, Reborn felt that the transportation technique was familiar, but couldn't put his finger on how. Nova had settled him on the fence beside her as Tsuna's class came outside for gym. Looking down at the espresso in his hands, Reborn couldn't stop himself from asking, "Why?"

Nova smiled lightly while gesturing to the class, "I set something up that I doubt you want to be caught in."

Reborn suddenly remembered the look on Tsuna's face this morning and how the caramel haired boy had seemed to become resigned after reading a note that had appeared on his desk. Glancing at the Sky, Reborn couldn't stop himself from asking, "Is that why Tsuna looked so resigned this morning?"

Nova let out a soft laugh as the odd ferret around her neck seemed to pur, "Of course, Tsuna's used to my ways of making his life interesting in order to ensure he survives."

"Did he know about..." Reborn trailed off as Nova shook her head and gained a dark look on her face.

Reborn felt a shiver go down his spine at the sight of it and the fact her Flames seemed to darken in response. A chill seemed to fill the air as Nova said, "No. The bastard that sired him kept Tsuna and Nana well away from any information about the mafia. He even did something drastic just to ensure that Tsuna wouldn't become informed as well as to ensure he wouldn't have to stay with his family here."

Reborn's eyes narrowed at that and began putting things together. With a harsh growl, Reborn demanded, "Did the bastard-"

"Seal Tsuna?" Nova cut in earning a tense nod, "Indeed. I managed to convince my guardian to get him unsealed a year afterward, but it still did damage,"

Reborn bared his teeth as forgotten instincts reared up. If there was one thing Reborn wouldn't stand, it was causing unnecessary harm towards children. The only reason a Flame user's flames would get sealed was if they did something so sick and twisted no one would argue with. You had to have the agreement of not only the Vindice, but every Mafia boss and Arcobaleno. No one sealed a Sky as the repercussion were far more horrible than with a regular Flame user. To put it simply, the only people that ever got sealed were adults. No child was sealed, but it seemed that Iemitsu hadn't gotten the message.

A calming hand was placed on his shoulder as Sky Flames caressed his Flames. Reborn noted that they had left their perch on the fence and the blackened ground around him. Nova looked at him with a frown on her face. Taking a deep breath, Reborn forced himself to calm down down, "Thank you."

"No problem," The Flames withdrew slowly and Nova let go of him once she'd figured he was truly calm, "Iemitsu will be getting his dues when the time comes, but until then, we're making things difficult for him,"

"How?" Reborn asked earning a devious smirk from eighteen year old Sky that reminded him heavily of a cat.

Nova returned to her place on the fence with Reborn following her, "It's good to have money to spare."

Reborn chuckled softly at the vague answer. When a shout rang out from the field below them, Reborn turned to look only to let out a startled laugh. Someone had managed to turn the grassy field into a children's paradise. Trampolines and hundreds of other squishy things decorated the field causing people to bump into them as they struggled to stay upright. Ball and balloon pits filled other areas. Some of the teens below them were covered in various substances with some seemingly tarred and feathered. Running all around the area were startled looking animals ranging from chickens, pigs, dogs, and cats to more wild animal though none seemed to be acting like usual.

When Tsuna came to her house after school with a pissed of Kyoya, Nova grinned brightly at the tired teens, "Have a good day?"

"I hate you so much," Tsuna grumbled as he slumped into his regular chair.

Kyoya growled at her, "Carnivore, I will bite you to death for that."

Nova smirked at him, "We can play later. I'd rather have you in top form as that is far more enjoyable."

Tsuna looked at Reborn as the Arcobaleno stared between Nova and Kyoya, "Surprised?"

"How are they..." Reborn trailed off.

"Nova challenges Kyoya and forces him to improve," Tsuna explained with a slight smile as the feral teen that was his Cloud left with a slight huff, "Nova helps me do the same,"

Nova disappeared into the kitchen as Reborn asked, "Has she taught you about your Flames?"

"A bit," Tsuna closed his eyes and laid his head on the table, "She's taught me about keeping them from being sensed by other Flame users and ensuring they're strong. She hasn't taught me much about using them as she felt control exercises were more important. Of course, she also mentioned that it would be best for my actual teacher to do the teaching,"

Reborn shook his head lightly. Of course, Nova wouldn't really do much in terms of training Tsuna. Given that she was also a teenager herself and saddled with her own powers to learn how to wield, he couldn't blame her. From his cursory check on her, Reborn could only wonder how she dealt with it. To have so much power in such a weak form, it could only make things difficult on her. Reborn did have to wonder who her Guardian's were. The dog animagus was one of them, but not a main guardian. As for the werewolf, Reborn couldn't sense a connection between the two. Reborn would need to do some in-depth research on the eighteen year old Sky.

Nova laid back against her pillows and smiled softly at the mirror in her hands, "Everything alright, Big Brother?"

Skull grinned at her with his octopus partner on his shoulders, "Yeah. It's actually kind of fun. No one's really too pushy or mean, but I wouldn't put it past them to try something."

"Just be careful and come home in one piece," Nova worried for her big brother, "I really miss you,"

Skull lost his grin and sighed softly, "I'll try, but you know how things are. Sometimes my injuries are unavoidable."

"I know," Nova ran a hand through her hair.

Skull smiled at her, "Don't worry too much about me, Kid. I'll be fine and we can see each other again soon."

Nova smiled at him in return, "I'm a worrier, Big brother. It's just how I am."

The Cloud shook his head, "Before I go, how is everything?"

"Reborn's appeared," Nova offered earning a loud laugh and impish grin from the Cloud.

"Do tell," Skull leaned towards the mirror with a puppyish expression on his face.

Nova put the unbreakable mirror into it's holding case before turning towards the window as she mused over what the next few months to a year would be like. Tsuna would grow stronger and stronger while gaining so many allies. She knew his pride would form and become strong enough to brave the Mafia world. She worried over certain points especially the parts that seemed to change every few moments. She knew those points had to do with Tsuna's would be Lightning Guardian, but not why. Letting out a deep sigh, Nova laid back and wondered about that. With her soulmate, the future was blurred in places and with her instincts, she knew they would most likely stay that way where he was involved. The little Lightning causing rapid changes in the future and making it seem like nothing was set irritated Nova. The future only changed in her visions when she actively did something to change it or caused a change. As a result, Nova would be keeping an eye on the Lightning brat until she figured it out.

When her window opened, Nova didn't even twitch as Reborn entered. Cyala glared at the Sun Arcobaleno, but stayed on the bed with Nova. Reborn seemed startled to see the dragon, but shook it off rather quickly. She spoke while running a hand over Cyala's warm scales, "Ask your questions and I will attempt to answer them."

"You're the supposedly dead 'Girl-Who-Lived'," Reborn stated earning a light nod, "How come the English magicals haven't realized that yet?"

"The Goblins there have ensure that if anyone comes hounding for my money, they'll discover that a 'forgotten' branch of the family exists," Nova was quoting her mentor on this, "As vaults always go to those with the strongest claims once a family dies, no one will really question where the money went besides the usual what family has it and why,"

"What if someone comes looking for you in order to get funding?" Reborn asked while taking a seat on the windowsill as Fon often did.

Nova briefly wondered how her Storm guardian was doing with his little apprentice before returning to the matter at hand, "Fail safes have been put into the place so that only the smartest or persistent enough, they will be allowed to meet with me to plead their case. In the past, Auntie was the one that met with them, but since I'm eighteen, it's my turn."

More along the lines, Nova had insisted on this clause. She would have to deal with the English magicals as that was unavoidable. The same could be said for her eventual confrontation with Tom Riddle as the madman won't stop coming after her due to the prophecy. It's funny that no one thought that it might mean another dark lord and another savior. Internally shaking her head, Nova looked at Reborn as he gave her an irritated look, "I can't find anything on your Guardians other than Black. I'm also curious as to why you haven't bonded with the Wolf."

"My Guardians do not wish to be known as that would paint a rather large target onto my back," Nova paused for a moment, "Well, larger than it already is. I also wish to see how long it takes you to figure it out," Reborn scowled at her, "As for your second question, I simply do not have any reason to bond with Lupin. As of yet, he is still a threat to my safety and life here. He's a stubborn Lightning that will see nothing wrong with what Dumbledore had done or will do. Until proof comes along to shatter this view of his, I will not bond with him. Even after that, I won't bond with him as I know exactly who my Lightnings will be and he is not one of them,"

Okay so Nova might be a little more stressed about the whole constantly changing future thing than she wanted to admit. She was also a bit too tired to think of being cryptic about this stuff. Shifting until her back hit the pillows, Nova waited for Reborn to take all that in. When finally spoke, Nova found herself sighing in relief, "That was all that I wish to know at the moment."

"I will see you tomorrow then, Ren," Nova told the Sun, "If you want, I can give you some espresso tomorrow,"

Reborn paused before replying, "I would enjoy that."

Without another word, the hitman left and Nova waved her hand to close the window. Sighing deeply, Nova looked at her familiar and Flame companion, "Things are going to be interesting from here on out, Cy."

Cyala hissed and nuzzled her with a scaly nose.
