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

Bright emerald green eyes specked with indigo and orange flecks watched as a boy five years younger than her tripped. She frowned upon seeing the other kids just laugh at the five year old and mentally sighed. She knew who this kid was, or rather, who he could. He was the whole reason that she even decided to come to this little town when her mentor and guardian placed her in Japan. She should leave him be and let the future go it's course. She really should, but looking at those caramel colored eyes and feeling that seal clipping his metaphorical wings. With a low groan as her instincts nudged her towards the boy, she carefully reached out and bent down, "Need some help?"

The boy let out an adorable squeak, "HIE!"

"Need some help?" She repeated in her accented Japanese.

The boy stared at her with those doe-like caramel colored eyes for a few moments before taking her hand. With a warm smile, she helped him up and brushed off his clothes. The boy spoke up as she took a step back, "W-why?"

"You needed help," And her mentor was likely going to kill her for this, "Want to be friends?"

"F-friends?" The boy asked with wide eyes, "R-really?"

"Mhm," She nodded lightly and the boy nodded with a small smile, "Cool, my name's Noir Nova though people call me Cheshire too,"

"S-Sawada T-Tsunayoshi," The boy with restrained Sky flames replied, "P-please c-call me T-Tsuna,"

Nova nodded with a light smile, "Want to come to my house? I have some games we could play."

Tsuna hesitated before nodding with a relieved smile, "I-i'd l-like th-at."

It was just luck that her mentor was at the house when they arrived. Tsuna squeaked at the sight of the purple cloaked toddler while Nova grinned brightly, "Auntie!"

"Mou, who is this?" Viper, known as Mammon to the Varia, demanded.

"He's a new friend of mine," Nova answered easily while taking off her shoes and moving towards her mentor, "We were going up to my room to play some games I have,"

Nova peered at her mentor with careful eyes while trying to convey that she needed this. Eventually, Viper replied, "He stays for two hours, no more. We have work to do afterwards."

"Of course," Nova easily agreed before grabbing Tsuna's hand, "Let's go, Tsuna!"

They headed up to her room and Tsuna asked, "W-who was that?"

"My current Guardian. She has an illness that makes her look like a toddler when she's really an adult," Nova answered while going to grab some games that would actually improve the boy's learning skills, "She's related to me somehow, but I'm not really sure other than it's on my father's side of the family,"

"W-where a-re your p-parents?" Tsuna asked her with a small frown.

Sighing slightly, Nova told him, "They're gone, Tsuna. They died when I was really young. I don't remember them much."

"HIE! I didn't mean to make you sad!" Tsuna shouted with wide eyes.

Nova waved away his apology and got him settled down with a careful brush of her Sky flames.

Viper stared at her charge with a frown, "Why?"

"I saw what he was to become and what he could become with a little help," Nova explained with a low sigh over dinner, "My instincts demanded that I help him and be his friend. I need to stay here,"

"Mou, I should charge you for doing this," Viper growled softly at Nova.

Viper would allow this for a few reasons. The boy was a sealed Sky-Who the hell would be stupid enough to seal a Sky, let alone one so fucking young! The boy would be a good companion for Nova as she needed friends her age. Viper also knew what happened when you didn't follow along with Nova's visions. Her current form was a damn good reminder of that fact and left a severely bitter taste in the misers mouth. She still remembered Nova's screaming as Viper left for that last 'mission' and the tears that ran down her cheeks. She inwardly flinched and forced her mind away from it. Nova smiled warmly at her, "Thank you, Auntie."

Viper almost snorted before asking, "Have you chosen what other weapons you wish to learn?"

"A sword of some type and perhaps a gun of some type," Nova answered in a light tone, "Professor Sorin has remarked that my skill with smaller weapons and traps is getting better. I might be able to master my knives within the next year. I've also been picking up some martial arts. It isn't much right now, but with my skills in dance and gymnastics, I should be able to go deeper once my other school starts next month,"

"I will pay a visit to get a progress report before I leave," Viper wondered briefly if speaking to Fon would be a good idea before squashing it.

Nova began speaking of her latest accomplishments both legal and illegal. Viper was heavily amused at how someone that had once been meant to be completely civilian and an English witch turned out this way. She didn't regret getting her charge involved with the mafia at a smaller scale and knew that Nova would thrive no matter what. The fact that she didn't care about her English heritage or what the magicals in her home country thought of her just added to her amusement. Viper did have some regret that Nova had lost her innocence, but knew it was unavoidable due to her gifts.

Nova was a seer much like Luce's family and had instincts that rivaled the Vongola intuition. Both of her gifts were powerful due to the high mix of flames and magic running through Nova's veins. The only bad part of it all was that Nova's body was on the weak side. With potions and training, Nova could fight as well as anyone her age, but her powers had to be strictly monitored. If used too much, Nova would suffer from a severe attack which could put her out for a week or more depending on how severe. Viper inwardly shuddered as she recalled the first attack she'd witnessed and knew that the image would haunt her for the rest of her life.

While Viper could contact the other Arcobaleno for assistance, she was highly reluctant to allow any of them near her student. Reborn would likely worsen Nova's attacks with his chaotic ways. Verde would use her as a science experiment even if he could probably figure out a way to ease Nova's attacks. Lal would probably sell Nova out at some point as the woman worked with CEDEF. Colonello might work, but he was very busy with Mafia land. Viper briefly considered Aria before scoffing softly as the new Sky Arcobaleno didn't meet her standards. The only ones Viper would consider allowing near Nova were Skull and Fon. Fon would be a good teacher for Nova, but he was busy with his Triad. Skull would be good company, but was far too clumsy and would probably get Nova into trouble frequently.

Dumbledore paced lightly as he waited for the quill writing the the addresses of the new Hogwarts' students. The last few years had been rough on him as he couldn't find Harriet Potter anywhere. He had known that leaving her with Petunia would be a mistake, but he had no other choice. Petunia was the only muggle relative that Harriet had and wouldn't spoil the girl rotten before she entered Hogwarts. Dumbledore knew that Harriet would likely have a rough childhood, but she needed to know what Tom felt growing up in order to understand him correctly.

Dumbledore hated to pit her against Tom, but it was the only way he could see the prophesy being completed. Harriet would die, but it was for the greater good of the world. He sighed heavily only to feel his heart drop upon hearing Minerva swear and mutter, "Her name wasn't written."

"What!" Dumbledore rushed over to the desk and looked through the letters, "Her name has to be here!"

"It isn't Albus!" Minerva stopped him with a harsh shout, "Stop this madness,"

Dumbledore fell into the chair on the other side of the desk. Dumbledore only knew of two outcomes that could be possible in this situation. Either Harriet Potter was going to another magical school somewhere or she was dead. Seeing as Dumbledore hadn't gotten any owls from other magical schools crowing about having the savior in their school, he knew that the Potter child was dead. With a heavy heart, Dumbledore turned towards Minerva with a tear filled gaze, "Harriet Potter is dead."

End!
