AN: Bahaha, definitely, DEFINITELY, should not be uploading new stories, when I can't even update the ones I've already got, but... well, here ya go anyway!

"Dame-Tsuna!"

A sharp smack to the back of his head brought Tsuna crashing back to reality. Reading through the letter that his mother had handed off to him (with a joyous smile on her face) once more, wide chocolate eyes only got wider. "Eh? Ehh? HIIIEEEE!"

"Isn't it amazing, Tsu-kun?" Sawada Nana, not seeming to notice the distress marring her son's face, gushed happily as she served up everybody's breakfast. "Our family's getting bigger!"

Those were not words that Tsuna wanted to hear with Reborn around. Already he could feel the infant hitman's black eyes trained on him inquiringly (threateningly). Tsuna debated not giving in, just this once, but of course, the moment the thought entered his head, he found himself face-to-face with a green Leon-gun. Screeching in alarm (although he really should be used to this by now), Tsuna handed the piece of paper off to his smirking tutor; inwardly praying that Reborn wouldn't feel the need to recruit his newfound cousin into his so-called 'Famiglia'.

"Oh?" Reborn spoke up, eyes still roving over the page in his hand. "I wasn't aware that you had a sister, Mamma."

Actually, Tsuna hadn't known that either.

Nana pouted a bit as she added more pancakes to the stack in the center of the table. "Mou, Reborn-kun, that's because Aneki is too stubborn! I haven't seen her since the day of me and Iemitsu's wedding!"

"Mamma has an older sister?" Bianchi asked curiously. Tsuna thanked all the gods he knew of that the Poison Scorpion was sitting and eating for once, instead of assisting with the cooking.

"Mm-hm!" Nana nodded enthusiastically. "Her name is Nazuna, and she's three years older than me."

Tsuna, having only just learned his Aunt's name when he read the letter, felt a little blindsided by the whole thing. He took comfort though, in the fact that at least his mother's family was normal. No mafia, no hitmen, no supernatural curses, ghosts, or flames.

"So has she finally got in touch with you, after all this time?" That was Bianchi again, leaning forward interestedly. Tsuna wondered if she was concocting her own version of what had happened between the sisters, with plenty of familial love and drama.

"No, no, the letter's not from Aneki." Nana's pout intensified for a moment, before she dropped it entirely, in favor of beaming at the letter in Reborn's tiny hands. "It's from her son! His name is Tetsuya, and oh, he seems like such a lovely boy. Tsu-kun, it seems like you're around the same age, you should write him back!"

"Eh?"

His mother finally seated herself, in between Lambo and I-Pin (who had, for once, been behaving) with her own plate of pancakes.

"Well of course I'm going to reply, but you should include your own letter too, Tsu-kun! Tetsuya-kun went through so much effort to find us and make contact, the least we could do is write back."

Tsuna couldn't exactly disagree, but… What was he supposed to say?! 'Hello cousin, it's nice to hear from you, my name is Tsuna and apparently I'm going to be a Mafia Don'?

Not that Tsuna was any more accepting of his position in the Famiglia, but if he was being completely honest with himself, well. He was probably going to end up as the head of the Vongola, whether that be a mafia family, a vigilante group, or something completely new.

And legal.

The feeling of cool metal touching his temple broke Tsuna from his internal musing, and he jerked back with a "Hiiieeee!" Just to see Reborn pointing the Leon-gun at him once more. "Of course Tsuna will be glad to write his cousin back, Mamma," Reborn answered for him. "It'll be good for him, to have more family members."

Tsuna could only groan miserably as his intuition flared warningly in the back of his mind.

AN: I have no idea why the idea of a KNBxKHR xover was so appealing to me, especially as I don't even have a plot for it. Oh well, it'll just be another flash-fic of character interactions. ALSO! Guys, the KHR fandom has some amzing writers in it. I highly, HIGHLY recommend War Torn by CamsthiSky and Dead-Eyed Tsuna by Wyrvel. They're both amazing stories, I love them so much. Can be found in my favourites list. Let me know your thoughts on my own writing!
