AN: This must be my fastest update ever! Don't expect it to happen too often guys, I'm real shit at keeping to schedules haha. I just wanted to do something for y'all, coz you're showing so much enthusiasm for this. It's appreciated3.

Reborn, unsurprisingly, was not at all fond of Sawada Iemitsu. He was good at his job as the head of the CEDEF, but he was so damn annoying that the hitman just couldn't bring himself to like the man. He was also an incurable idiot, a statement compounded by the fact that he had never once mentioned his wife having a sister.

Waiting at the train station for the Sawada's newest guest with Tsuna, Reborn once again felt the urge to drop-kick Iemitsu off the edge of the Earth. When he had called to question the deliberate omission of information, all Reborn had gotten for his trouble was loud wails and sulky mumbles about 'that evil woman trying to stand in the way of our love!'. He gathered that Sawada had probably kept an eye on the woman, to feel comfortable not acknowledging her existence to the hitman living in his wife's home, but it was still inexcusable to Reborn.

Revenge would be had.

Beneath his feet, Tsuna shivered. "Are you thinking about crazy things again, Reborn?"

Just because he could, Reborn pulled on two thick handfuls of the fluffy brown hair he was standing in. Smirking sharply at his student's startled yelp, the infant dropped to stand on Tsuna's shoulder instead. The young Decimo had come a long way from the Dame kid that he used to be; his Intuition was growing by leaps and bounds, and it even looked as though he was finally growing a spine (although Reborn would have to punish him later for daring to use that newfound courage to defy him). "You don't have time to be thinking about what I may or may not be thinking of, Dame-Tsuna. Isn't that your cousin's train that just arrived?"

"Huh?" Tsuna's head whipped around, brown eyes widening to a ridiculous degree.

Reborn snorted, keeping one eye on the disembarking passengers and one on Tsuna. His observation skills were still appalling when his life wasn't in direct danger. That would have to change.

He spent the next six-or-so minutes thinking up new ways to tor-tutor the teenager in the ways of a mafia Don, and occasionally pinching the skin of Tsuna's neck when it looked like he was working himself up into an unnecessary frenzy. His hair seemed to be getting fluffier by the second.

"Hello!"

Pink. A teenager with hair the colour of candy-floss had skipped up to them, recognition on her face. Reborn certainly hadn't missed the girl's approach, but it was still startling to have such a bright person pop up in front of them like that. From the way Tsuna was screeching, he agreed.

"I'm Momoi Satsuki! It's nice to meet you, Sawada-kun!" The girl, Momoi, beamed at them, apparently unaffected by Tsuna's startled garbling about 'Who are you, how do you know my name, ReBORN DID YOU BRING HER HERE'.

Reborn wasn't listening, too busy focussing on the boy that was standing next to Momoi, eyes and hair like the sky, and a low enough presence that the World's Greatest Hitman had instinctually deemed him so non-threatening, that he was basically part of the background. It had taken a second sweep of his eyes for Reborn to actively realise that another person was standing there.

"Hello."

Tsuna screeched again, and Reborn found himself smirking. Unusual an ability as it was, it no doubt came in very handy. "Dame-Tsuna, is that any way to greet your cousin? First impressions are everything, you know." He pinched the boy's earlobe between two tiny fingers, just because he could.

"Reborn!" Tsuna yelped. "My- my cousin?" Startled brown eyes locked with unassuming blue. "Tetsuya?!"

The other boy offered up a small smile. "It is nice to finally meet you, Tsunayoshi-kun. I apologise for not warning you that Momoi-san was the friend I was bringing with me." He bowed politely.

"No, no, it's okay!" Tsuna waved his hands frantically. "You guys just startled me, that's all. It's good to meet you both!" He smiled sheepishly. "I'm Sawada Tsunayoshi, although I guess you already knew that, Momoi-san. And this is Reborn." He gestured at the baby perched regally on his shoulder.

"Ciaossu."

The walk back to his house was surreal for Tsuna. Reborn had shifted to Momoi's arms the moment the girl had requested it, and left Tsuna to make embarrassed apologies to his older cousin for his reaction to Tetsuya's sudden appearance. He had mentioned it in their letters, but Tsuna still couldn't quite believe it; magical fire and time travel aside, it was one of the most impossible things he'd ever seen (or, as the case may be, not seen).

"It's useful for my basketball," Tetsuya was saying as they slowly ambled down the streets of Namimori. "And for sleeping in class after morning practise."

Tsuna couldn't help laughing, finding the second half of the statement an absurdly Yamamoto thing to say. "I have a friend who would kill for the ability to hide his mid-class naps."

They chatted lightly all the way up to Tsuna's front door, where Nana was anxiously waiting. Tsuna noticed the way her eyes were roving back and forth, searching for her nephew, and shot a triumphant look that he knew he'd pay for later in Reborn's direction. That was the normal reaction to his ghostly cousin's presence (Dame-Tsuna, you aren't a normal person, you're the heir to a mafia Family). "Ah!" Nana jumped a little as the group got closer and her eyes finally settled on Tetsuya. Her smile could have outshone the sun. "Tetsuya-kun, oh my goodness! You look just like your father!" She swept him up in a hug, and let him go only to greet Momoi just as enthusiastically. "It's so lovely to meet you, Tetsuya-kun, Momoi-chan! Come on in and meet everybody, they're just finishing up with dinner…"

Nana retreated further into the house, calling out to the kids and Bianchi. Tetsuya and Momoi followed Tsuna in, removing their shoes and letting out identical 'pardon the intrusion's. Tsuna sighed a little as he felt his intuition tugging at him. At Tetsuya's blankly quizzical look, he grinned ruefully. "You'll see," he said, inwardly praying that the weekend would only consist of normal insanity, and not the type of insanity that made Tsuna want to burn the entire mafia to the ground. "Just- welcome to the chaos."

AN: Short and sweet :). Also, a note - the KHR timeline has been moved up a bit, so it's in the more modern times of KnB. Takes place post-Winter Cup for KnB, and post-Future Arc for KHR (also delaying the Shimon Arc a bit, because they're only just out of sync). Thanks so much for reading guys, feedback appreciated like always!

RECS:

First is Sincerely, Scattered Shards by You Light The Sky. Unfinished at this moment, but SO SO BEAUTIFUL. Very feelsy, go read it. And the other one is The Tempest Temptation by Luki Dimension. It's ongoing, published kinda recently (by which I mean this year), but it's so interesting, and a pretty original take on a favourite trope. Check it out!
