Reborn was many things, but oblivious certainly wasn't one of them. His new student was surprised, but more exasperated than shocked at the news he was part of the Vongola.
The fact that upon seeing the family tree, he immediately went and pulled out a much more extensive one that included a pair of cousins he was entirely unaware of at that point that were also descended from the Primo, at least on the Japanese side did not help.
He also found it highly suspicious that his new student shared the same room as a thirteen-year-old abused Mist with a soft Flame that was just barely Active. A teenage girl should not be so at ease with sharing a room with a teenage boy, especially since the two behaved more like siblings.
Reborn had been given the most "recent" file on his new student. It had been updated the last time Iemitsu came to visit, and should be fairly accurate.
There was nothing in it about Tsuna living with a Mist, or the fact that he was friends with a Rain Latent who was clearly a natural hit man or on good terms with Fon's grandson to the point that Tsuna was the Cloud's secretary.
However his biggest clue to Iemitsu's sheer incompetence came when he brought the potential Storm Guardian to test his new student, since he apparently had very overprotective friends.
Tsuna took one look at the set up and Reborn saw something rather concerned.
Genuine fear.
Tsuna clearly wanted to haul tail the other direction, and only slightly calmed down when it became clear Gokudera Hayato wanted to 'prove' himself a better Decimo candidate.
Reborn finally got to shoot the boy with Dying Will Bullets...only to stare in shock and inwardly swear that he was going to murder Iemitsu in the most brutal fashion he could come up with.
His student was a girl. There was no mistaking the still-developing bust line that was thankfully hidden by a sports bra, and a pair of odd shorts that could have passed for boxers.
Once Tsuna, which he was highly doubting was her name in the first place realized her state of undress, she let out a panicked shriek.
What she did next made the decision to brutally kill Iemitsu a priority... because if that wasn't Sky Haze he'd eat his fedora.
"What just happened?" asked Hayato baffled. One minute the Tenth was there, the next she shrieked and disappeared in the span of a second.
"It's called Sky Haze. A flame technique available to Skies that allows them to perfectly harmonize with their environment to the point they become relatively invisible to the naked eye unless you have thermal imaging. It takes a great deal of control to pull it off, however," explained Reborn.
Which begged the question how the hell she knew how to do that at the drop of a hat and with the seal supposedly intact.
Tsukiyo POV
She was shivering under Hibari's desk. Thanks to Sky Haze, she had managed to reach his office without anyone seeing her half dressed.
Kyouya came in like a storm cloud, took one look at her and without saying a word wrapped his jacket around her.
"What happened?" he demanded, once her shivers started to calm down.
"Reborn hit me with some weird bullet... I woke up in a secluded area with that new transfer with nothing but my underclothes on and him staring at me in shock. I came here immediately."
Kyouya's face was furious.
"What."
"I really don't want to go home. I have no idea if Reborn is going to hit me with one of those bullets again," said Tsukiyo shivering.
Kyouya immediately called Chrome in. Fortunately his Sky knew where he lived, and Chrome was good enough at her illusions to hide the fact they had left school.
Predictably, his Sky had nightmares the second she tried to sleep. He relented and allowed her to use him as a human teddy bear considering out of all her current Guardians he was the strongest and most territorial.
Reborn was not expecting Fon to call him directly. Or for the rather irate Storm to read him the riot act for the stunt he pulled with the potential Storm Guardian.
She hadn't rejected Hayato outright, but it was a shock finding out his new student had an actual fear of being assaulted by her classmates to the point she created an entirely new identity that made everyone believe she was a boy including her own mother, and had made it a point to never, ever go anywhere that wasn't patrolled by the Disciplinary committee to the point the worst she endured was a few idiots attempting to trip or knock her books out of her hands.
Most of which had stopped the moment people found out Hibari liked her enough to make her secretary, though no one was aware that "Tsuna" was in fact a girl.
That he had apparently acted out one of her greatest fears without realizing it did not sit well with him. Especially considering she had a valid reason for having it in the first place.
So he reluctantly decided to wait for Fon to arrive before properly introducing a potential Storm to his new student.
Assignment or not, he refused on principle to exacerbate that sort of fear into a full blown phobia.
Fon arrived in very short order and he was not pleased with Reborn's stunt in the least.
"What can you tell me about Tsuna?"
"Her name is actually Tsukiyo," said Fon.
"Care to explain why she has that particular fear?"
"To sum up a long story, she was twelve and she looked up what the word 'whore' meant and accidentally clicked the wrong links. As such she was made very, very aware of how quickly things could turn for the worse if she allowed her gender to be known considering the fact the adults have a general apathy towards her and her own mother is oblivious to anything that doesn't involve Iemitsu."
Reborn frowned.
"And before you ask, I confirmed Nana's general lack of interest towards her children. She might look like an 'acceptable' mother on the outside, but her behavior took a complete one-eighty the second Iemitsu showed up. She paid exclusive attention to his words and only cared for her children as an after thought."
Reborn continued to make murdering Iemitsu a higher priority. At this rate he was going to hunt down the idiot and shoot him, assignment be damned.
Hayato quietly followed them to a neutral location, and was properly introduced to his potential Sky.
Tsukiyo had calmed down quite a bit, and it didn't hurt that Fon let her use him as a sort of 'teddy bear' while Reborn patiently explained why he had brought Hayato in the first place.
"Someone mind giving me a proper profile, since clearly everything I have on Tsukiyo here is clearly full of crap?" he asked patiently.
Fon snorted.
"Iemitsu hasn't paid real attention to his family since the day he put his job first, and we made very sure he had limited to no contact the last time he visited. As for a proper file I can probably make something close to the truth up...provided you don't use Dying Will bullets on her again. We're still trying to get her used to the idea of wearing female clothing instead of hiding behind the boy's uniform."
And that was only possible because of Chrome and Kagome, who were doing wonders for her self confidence as a female.
Reborn hummed.
"Just out of curiosity is there a line yet for brutally murdering Iemitsu?" he asked.
"Not yet," said Fon amused. Reborn's eyes gleamed hearing that.
Tsukiyo sat down with Hayato and carefully broached the topic of him becoming her new Storm. Fon was good, don't get her wrong, but having an Arcobaleno openly acting as her Storm put a massive target on her back. Besides, he really reminded her of a younger, grumpier G and that was enough to at least hear him out.
The second she got even a fraction of his history, she decided that even if he didn't become her Storm Guardian she wasn't going to let him suffer being an independent any longer.
"Reborn, I have a hypothetical question. Does the Right Hand have to be one of the official Guardians or can it be someone who's loyal, but not harmonized?" asked Tsukiyo seriously.
Reborn blinked.
"It would be unusual, but not unheard of," he conceded. "But it's highly recommended that the Right and Left hand be one of the Guardians if the Don or Donna is a Sky. Mostly so no one questions their loyalty without a damn good reason."
Hayato perked up hearing that, already guessing where this was going.
"Right hands are basically like personal assistants, but with a bit more authority and power, correct?"
"More or less," agreed Reborn.
"Well I'm not sure I approve of the current Vongola, but I could use a decent Right Hand. Even if you don't become my Storm, that doesn't mean I won't take you in," said Tsukiyo.
Seeing the shocked and hopeful look on his face made her heart break. Despite the scare he had given her two days prior, she pulled him into a hug.
He latched onto her without hesitation, and she could feel some of the tension release from his body knowing that she'd accept him as one of her own even if he didn't become her Storm.
"Now, where exactly are you staying? I know for a fact that renting apartments doesn't come cheap, especially since your weapon of choice is something that is very hard to get legally," asked Tsukiyo seriously.
"Little moon, what are you planning?" asked Fon.
"Chrome shares my room since she rather enjoys having another girl to talk to, and Tatsuya has his own room. And since Reborn insists on sleeping on that ridiculous hammock in my room, that means we might be able to clean out the attic or something and get an extra futon for Hayato to use. It's not like we have that much stuff up there anyway, and we can always move things to the basement," said Tsukiyo sensibly.
Reborn looked at her with open approval. A good boss took care of their subordinates, after all.
"Ahahaha... if that doesn't work out we do have a spare room at my place," offered Takeshi.
"You're just hoping to play out some of the scenes in the books I gave you for your birthday," snorted Tsukiyo. That Takeshi didn't even try to claim otherwise said volumes about his preferences.
"What books?" asked Reborn.
"Clearly you never bothered to look at my collection on the shelf," said Tsukiyo.
"I thought those were Chrome's."
Chrome shook her head.
"They were there long before she saved me. She originally bought them to poke fun at Ieyasu's secret relationship with his boyfriend, but got hooked on them instead."
"Who is Ieyasu?" asked Reborn frowning.
Fon shared a look with Tsukiyo. He was desperately trying not to laugh at the thought of how many headaches it would cause Reborn to learn that his new student was already getting lessons from the man who created the very famiglia he was teaching her to lead.
"Ieyasu is an older brother type figure who has a Sky Flame. He was the one to discover her seal and remove it, and has been teaching her the finer arts of how to use it. So far she has already harmonized with Kyouya and once Takeshi goes active there's a high probability he will become her Rain and Left Hand. Ieyasu's Cloud is the one who gave Kyouya a small list of tips on how to properly channel his Flames, considering how rare that one is," said Fon honestly...hiding the fact that "Ieyasu" was really Giotto and that she was able to visit him through a well.
Reborn frowned at that. He had no reports of an "Ieyasu" within the area.
"Is he trustworthy?"
Fon's smile hid the fact he was laughing his ass off inside.
"Reborn, if anyone has a reason to help Tsukiyo return the Vongola to what it should have been and not what it is now, it's him. Outside of that he has no reason to hate the Vongola."
He really, really hoped he was there the day Giotto found a way to come through the well and visit Tsukiyo, instead of the other way around. Since the ability was clearly genetic it was only a matter of time before he figured out how.
He was sure Reborn's reaction would be both hilarious and glorious to see. Ah, well. Even if he did miss it he was certain Tsukiyo would catch it. She was very good at photography and before Reborn showed up was seriously considering that as a career.
Odds were she'd keep it as a hobby or something.
On an unrelated note, Hayato opted to move in to TakeSushi for reasons he wasn't quite willing to go into. Tsuyoshi just asked that he kept anything explosive or chemical far, far away from the food and restaurant.
Considering his history with poisonous cooking, that was a request he could easily agree to.
Even if he did blush as red as a tomato when Tsukiyo busted him looking at Takeshi's ass, and discreetly slipped him one of her 'collection'. Along with a note.
'Who you date or what you do on your off time is your own business so long as it doesn't affect your job. That being said, this should give you an idea of Takeshi's preferences. Have fun!'
At least he knew she had nothing against him dating her Rain. Even if he wasn't quite ready to potentially start a relationship. He was still getting used to the idea that he might have found someone who actually gave a damn about him.
