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

Separate languages will be like this.

Tsuna took one look at the white haired male walking beside Nova as well as the large amount of food before commenting, "Bribery."

While he was wary of Byakuran, Tsuna would give him a chance if only because of how healthy Nova looked. As the years had gone by, Nova had looked increasingly tired and haggard. At the current moment, Nova looked well and truly rested. Tsuna was happy to see his big sister's eyes bright. With that in mind, Tsuna would give Byakuran a chance. Nova seemed to know what he'd been thinking and beamed at him, "Mhmm. So shall we go find the others and eat some lunch before getting down to the nitty-gritty?"

"Alright," Tsuna looked at Byakuran, "I am Sawada Tsunayoshi,"

Byakuran's eyes widened before he grinned at Tsuna, "Gesso Byakuran. It is a pleasure to finally meet you, Tsunayoshi."

"Call me Tsuna," Tsuna told the white haired male, "Being called Tsunayoshi makes me think I'm either in trouble or your an enemy," Byakuran nodded lightly, "None of us besides Nova is ready to put everything in the past, but we will try. Attack any of us and you'll have to face the consequences,"

Byakuran frowned slightly as he nodded, "I have no intention of fighting any of you without due cause. You're precious to Nova and harming you would be like harming her."

Tsuna smiled slightly, "Then we're good," Tsuna looked at his amused looking sister, "C'mon, we should get to the others before that food gets cold."

After a rather amusing amount of freak outs and weapon drawing, everyone settled down to eat the lunch Nova had provided. Byakuran sat next to Nova as he observed the goings on with a mixture of amusement and awe. Simon family was odd being earth Flame users, but easily fit in with everyone. Tsuna ensured his elements behaved while protecting his food from Reborn. The various Arcobaleno in the group either sat with their students or sat near Nova. Nova was currently deep in discussion with Verde, Spanner, and Irie about the box animals. Nova glanced at him and he smiled at her earning a beaming grin before she returned to the conversation. Byakuran had trouble believing that after what had happened in the future that everyone was willing to be around him. Hell, he still had some disbelief that Nova accepted him with open arms despite what his other self had done. Byakuran's attention was drawn to Skull as the Cloud Arcobaleno settled down next to him and commented, "You really should relax."

"What makes you think I'm not relaxed?" Byakuran was surprised to hear the Cloud snort.

Skull shook his head, "You may outwardly be relaxed, but your Flames are tense not to mention Nova keeps looking at you in concern. While most of us don't like you at the moment, we're willing to give you some slack since you haven't done shit yet."

"I-" Byakuran attempted to speak only for Skull to interrupt him.

"Nova wouldn't be around you if she didn't accept you," Skull informed him earning a raised eyebrow, "The fact that Nova's letting you touch her is a sure sign of that. If she didn't accept you, she wouldn't allow you to touch her. It's that simple,"

Byakuran looked at Nova and sighed a little before looking back at Skull, "It doesn't change the fact I feel guilty."

Skull grinned at him, "Which makes you a good person. If you hadn't felt even a small amount of guilt for what happened, we would've killed you," Skull turned to look at everyone with a small smile, "Take that future and use it as an example of what not to do, it will keep you straight."

With that, Skull walked off and Nova turned to him, "He's right, you know," Byakuran looked at his soulmate in surprise, "So long as you remember what happened in the future and make it a point to not do the stuff your other did, you'll be fine. Besides," she grinned at him, "You have me around to keep it that way."

Byakuran smiled at her in return as he realized that both Skull and Nova were right. Nova surprised him when she leaned into his side and kissed his cheek. He slowly wrapped an arm around her waist while feeling a burst of contentment. While he didn't love Nova just yet, Byakuran knew he would come to love her.

When Lunch finished, the trash was tossed and everything else was packed away. Tsuna looked at Nova, "Spill."

Nova sighed deeply, "As you now know, my ancestor and yours knew each other," Nova pulled out the box that looked exactly like the one her ancestor had given both Giotto and Cozarto, "My ancestor grew up with the two after his parents ran away from England in hopes of protecting him. At that point in time, the non-magicals were doing a purge and I think you understand what would've happened," Everyone grimaced at that, "Now, my ancestor gifted both your ancestors a box just like this one. Enma, do you have yours?"

Enma took out the box slowly, "I picked it up before we left the island."

"No one knows where the Vongola box is," Reborn added making Nova scoff.

"The box wouldn't be anywhere near the Vongola," Nova informed the group, "The box is here in Japan,"

"Huh?!" Alarmed shouts sounded.

Nova whistled and everyone fell silent while clutching their ears, "If everyone will be quiet, I will inform you of what occurred years ago," She saw nods while a few glares were tossed at her for the volume, "Giotto Vongola took the box with him when he left Italy. A few years before his death, Giotto hid the box in a way that only Ulric's descendant would be able to find it."

"So wh-" Tsuna began only to find himself silenced as Cyala appeared in dragon form carrying a familiar wooden box, "That was in the attic, I remember it from when Mom had us clean it up," Cyala carefully set the box in his lap before flying over to Nova and resuming her ferret shape, "You knew?"

"I had a suspicion that was only confirmed when I found my own box burrowed in the main Potter vault," Nova informed him.

"So..." Skull peered at the boxes than back at Nova, "What now?"

"Now we open the boxes," Nova picked up her box and touched the latch, "Just to inform you, it has magic on it so-"

"OW!" Twin yelps of pain sounded from both Decimo.

"In order to open it, the magic needs blood to ensure only those keyed to it can do that," Nova looked at the two in amusement as they stuck their fingers into their mouths, "Honestly,"

"You could have warned us," Tsuna whined at her.

"I was going to," She informed him.

Enma was about to speak when all three boxes were enveloped in light. Enma's glowed the red-brown color of Earth Flames. Tsuna's glowed the orange color of Sky Flames. Nova's glowed a mixture of midnight blue outlined in obsidian, the bright orange of Sky Flames, and the reddish purple stained gold that was her magic. The glow lasted all of five seconds before dying down as the lids opened with a hiss. A mixture of smoke and dust floated up from each box and they all covered their mouth with grimaces. With a flick of her wrists, Nova disbursed the cloud and everyone was able to breath easier. Opening the boxes fully, the three looked inside only to feel confusion. Tsuna looked at Nova, "Nova, why is there trash in these?"

"It's not trash," Enma informed him with a frown, "It's a mixture of metals and stones,"

"So what do we do with them?" Tsuna asked as everyone looked at Nova.

Nova gained a contemplative look on her face as she thought about it before recalling a rather odd dream she'd had a few days ago, "We need to go find Talbot. He'll have the answer we're looking for."

Well boys and girls, the next Arc is approaching and soon enough, the Arcobaleno will be free! I will be working on Hunter: The Witch, so see ya next week unless I get a hit of major inspiration.
