Prologue you're an uncle
Sitting at a desk in a well decorated office is a man with spiky black hair and red eyes. He had a slight buzz cut on the side of his head with a raccoon tail with three bird feathers tied to the base of his neck. He seemed to have a frostbite like mark on his left cheek. He wore a black jacket on his shoulders underneath it was a white dress shirt and a loosely knotted tie. He had his legs on the desk showing his black pants and boots. This was Xanxus Vongola the adopted son of Timoteo Vongola and leader of the Varia.
Right know Xanxus was looking over some of the documents he couldn't hand over to his second in command Squalo since it needed the authorization of the Varia leader. As he was looking into some foreign leader's assassination job he heard a knock on the door. Relieved to have an excuse to ignore the paperwork he said, "Who is it?"
"Nebbia of the mist division," Spoke the individual on the other side. This caused Xanxus to raise an eyebrow because it was unusual for someone outside of his elements to report to him. He pulled one of his x guns out and kept it pointed at the door from underneath the desk as he told the person to enter.
Nebbia looked like most of mist division keeping themselves concealed under a hood and baggy clothes. If not for the male voice Xanxus would have no idea if he was male or female. "What are you doing here trash," he asked.
"Forgive me for my intrusion master Xanxus but you wanted my report on the investigation as soon as I finished," Nebbia said.
Xanxus had to spend a moment trying to figure out which investigation the mist is referring to, but for the life of him he cannot remember which one. With everything going on with the memories of the alternative future, the fiasco of an inheritance ceremony, and the battle for the rainbow he could not remember what the mist was ordered to investigate. Deciding to pretend that he knew what the mist officer was talking about he said, "Okay trash report."
"Yes master. Upon receiving the sample of you DNA that you gave me I ran it through numerous databases to find and relationship matches," Nebbia said. As soon as he said that first part Xanxus instantly remembered the mission he sent the mist on. After the ring battles he was plagued in curiosity over who is biological father could be and told mammon to order one of her mists to look into the matter for him not wanting to waste any of his guardian's time with investigating. Xanxus decided to put his gun away and listen to the report honestly curious about the results.
"After about the fourth database search I found out that your biological father name is Xander Russo who was in Italy around the right time for a business trip before he returned to japan," Nebbia said.
"That name sound Italian why was he living in japan," Xanxus asked. He found the similarity in their names to much of a coincidence, and wondered if his mother had known originally who his father was and fell into disillusion later.
"He worked for a multinational manufacturing company and was in charge of the Japanese plants and came to Italy to give a progress report as well as answer questions pertaining to some questionable financial reports," Nebbia said. "The company fired him shortly afterward but he decided to remain in japan and found himself bouncing from company to company for the next few years."
"Why did he do that rather than return to Europe," Xanxus asks.
This question caused the mist member to stiffen before he appeared to get himself ready to dodge an attack. Xanxus saw this and had a feeling he was not going to like the answer. "He choose to remain in japan because it turned out his wife and daughter had grown to love it there and did not want to leave," Nebbia answered. As soon as he finished he dove out of the way of a flame of wrath bullet fired by Xanxus in a moment of rage.
Xanxus was beyond pissed. He was always considered a bastard by the other family members since Timoteo took him in, but hearing that he really was and that he had a half-sister had pissed him off. It meant that all those words used to describe him when he was little was all true. When he started to calm down after firing a few of his bullets at the mist. He noticed the mist had dodged the attack he must be one of the higher rank mist in the division if he managed to not die.
Hearing the gunfire and feeling the boss's wrath the other Varia members made their way to the bosses office. When they got their Squalo said, "Voi what the hell is going on?"
Mammon who had gotten a little taller since the curse broke but looked mostly the same looked at Nebbia and said, "Nebbia what are you doing here."
"I was reporting the results of my investigation to master Xanxus," He answered.
Mammon took a moment to remember the mission, but unlike Xanxus the mist officer was able to remember the mission. "I see I take it he didn't like what he heard," Mammon said.
"Shi, shi, shi, what investigation is the peasant talking about," Belphegor asked.
"After the battle for the rings Xanxus told me to have one of my officers look into his biological father and find out who it is," Mammon said. "I choose Nebbia because he is very thorough and rarely gives incomplete reports.
"Oh that's fascinating so what did this cutie find that angered the boss so much," Lussaria asked.
"I had just informed him he had a half-sister," Nebbia said.
"What the boss has a half-sister," Asked leviathan in shock.
Nebbia nodded his head and said, "yes her and her mother had loved living in japan that when his father was fired from his work he sought employment there to let them stay. That is as far as I got before I had to start dodging bullets."
Xanxus was still shaking in rage over what he had learned but figured he should let the agent finish the report. He put his guns away and nodded for the agent to continue while the other officers stayed as well wanting to learn more about the boss's family.
Xander saw the nod and continued the report, "you half-sister whose name was Elizabeth Yagami was about five years older than you."
"Was, is she dead," Xanxus asked noticing the use of past tense.
"Yes last year her and her husband got in a car accident with a drunk driver and neither survived. Your biological father died two years earlier with stomach cancer and his wife shortly after due to a heart attack," Nebbia said letting the information soak in.
"I see so my entire biological family is dead huh," Xanxus said. On the outside he showed a face of indifference but on the inside he was both sad and angry. One of his strongest belief was the importance of family and how it should be supported. He could not help but think if he had remained calm when he found out about his adoption and sought this information then he could have met his half-sister and her husband and maybe had prevented their death.
"Not quite master," Nebbia said. "Your sister did have a young daughter named Hayate Yagami. She just recently turned nine and after the death of her parents was placed in the custody of her supposed uncle on her father side."
"You don't believe he is her uncle," Levi asked.
"No I do not. The paperwork is all right and appears to be legit on the surface, but if you dig further into the information you would find that her father was an only child," Nebbia said. "I'm not sure who this mysterious uncle is since I have not yet been able to catch a photo of him and only his two secretaries visit Hayate to make sure she is okay. Even his supposed place of employment is false and they have never heard of him with the number he gave as contact leads to an untraceable line."
"Is it possible he knows of her relation with the boss and plans to use it against him," Levi asked.
"I'm not sure, but I believe it might be connected to something else. For the last year Hayate has been experiencing pain in her legs and recently lost her ability to walk. The doctors have no idea what is wrong with her and have done every test they could think of," Nebbia said. He then pulled out a file and placed it on Xanxus desk. "This is a copy of her medical file. I left another copy with the sun division since their medical knowledge surpasses my own and might have a better idea what is wrong."
"So you were the one who left that interesting file on my desk," Lussaria said.
"What did you learn," Xanxus asks looking at his sun officer.
"I'm not sure since I only just started when we heard the gun fire and came up here," he said. he reached over and picked up the file on the desk and read through it for a few minutes when he was done he closed the file and said, "I can't be certain but it might have to do with her flames the doctors there would have no idea how to test them and is the only reasonable explanation I can think of from the file but I would have to check her in person to learn more."
Xanxus spent a moment trying to think about what to do next. He didn't just want to knock on her door and say, "hello I am your mother's half-brother and this person is a doctor here to test and see if flames ignited from your very soul are causing your condition." Yeah that would go over well and most likely have the cops called in mere moments. Not to mention that if it wasn't flame related he would rather keep his only family out of the underworld if he can.
As if sensing the bosses thoughts mammon came up with a passible idea. "the hospital she visits tend to get visiting doctors from time to time we could have Lussaria be visiting to show them how to use some new equipment and he happens to hear about Hayate unique case and asks if he could use some of the more 'experimental technology' to find the cause."
"That's a good idea Mammon and she looks like just a little cutie I can't wait to meet her," Lussaria said.
Xanxus spent a moment considering the idea before he nodded his head and said, "Okay trash set it up. The rest of us will travel to Uminari and stay discreet till the results come in. From there we will decide our next course of action based on what they say." The other nodded and Squalo got on the phone to arrange a flight to japan.
Well here we are a new crossover idea that sort of just popped in my head when I was considering a different story all together. The story really started to form when I was considering making a challenge for other writers to try. The name of this challenge I plan to simply call uncle Xanxus. The rules of the challenge are quite simple since we know nothing of Xanxus biological father the challenge is that Xanxus decides to look for the man and discovers that he has a sibling and maybe a nephew or niece. You can choose anyone from any series as long as you can make it work and make some form of since. The idea of this challenge came from an interesting harry potter and hitman reborn crossover written by sakurademonalchemist called Wrathful skies where a female harry potter is Xanxus half-sister through the same mother but different father.
Just in case it was not clear enough this is occurring after the manga and will mainly feature the Varia with other reborn characters making brief appearances. I plan to make Hayate have sky flames but not flames of wraths. I plan to have each of the Wolkenritter be her guardians as well as Nanoha and fate but not sue on their flames type and have been changing it around in my head the only one I know for certain is fate will be lightning. So I am open for ideas on how should be which flame as well as a better tittle since Varia of the night sky was all I could think of and I don't necessarily like it.
