Summary: When Tsuna is five, Nana finally gets her act together and divorces Iemitsu. A little more than a year later, the two find themselves being welcomed into the Yamamoto family. With a proper father figure and a newfound older brother figure, Tsuna's first meeting with Reborn goes quite differently. Two-shot. No pairings. Family fluff.

SkyGem: Well…I don't really know where this came from…but I hope you like it, ne? And I acknowledge that this would make a pretty good multi-chap, so if anyone is interested in continuing it, it's (eventually) going up in the plot dump of my blog. The link can be found on my profile.

"Hello, Tsunayoshi-kun," said the kind man, a bright smile on his face as he bent down, bringing himself to eye level with the small brunet. "My name is Tsuyoshi, but from now on, if you want to, you can call me otou-san!"

Tsuna stared at the man with wide eyes, not able to believe what he was hearing, before ducking his head, looking down at his fidgety feet.

Tsuyoshi, seeming to misunderstand his actions, let out a soft chuckle, saying, "If you don't feel comfortable, though, you don't have to-"

"No!" Tsuna suddenly exclaimed, looking up with wide eyes, and Tsuyoshi's expression became confused. A bright blush crossed the little boy's face as he turned his face down again, looking shyly up at Tsuyoshi through his lashes. "Tsu-kun has never had anyone to call otou-san before…c-can Tsu-kun really call you that?"

Shocked, Tsuyoshi looked up at his fiancée, who would be his wife in a few weeks' time, for confirmation when he heard this, and she smiled weakly at him.

"Because Iemitsu-san is always busy with work, he never had time to come home much. The last time he came to visit us before we divorced was when Tsu-kun was two. He doesn't remember him."

Tsuyoshi looked back down at Tsuna, and when he saw that heartbreakingly hopeful expression on the boy's face, he couldn't help but curse at Iemitsu's idiocy; his son deserved so much more than this.

Not letting any of his anger at a certain blond show on his face lest he scare his new son, Tsuyoshi smiled widely at the boy and ruffled his hair, saying, "Of course I don't mind! As long as you don't mind sharing your okaa-san with me and your new aniki?"

"A-Aniki?" asked Tsuna in an unsure voice, and that was when he noticed the boy who was curiously peeking out from his hiding place behind Tsuyoshi.

When the boy met his eyes, he smiled and gave a little wave, saying, "Ohayou! My name is Takeshi! It's nice to meet you, Tsu-kun!"

"Oi! Stop bullying my brother!" shouted an eight-year-old Takeshi as he ran towards the bullies that were picking on Tsu-kun.

The three boys all ran away upon seeing him, and Takeshi didn't chase after them, thinking it more important to see whether his brother was okay and to get him back home.

"O-onii-san," sobbed Tsuna, immediately latching onto Takeshi the moment the older boy was within reach.

"Shh, it's okay, Tsu-kun, they're gone now, so let's go home, okay? Otou-san will make the hurt go away."

Tsuna just nodded wordlessly in reply, tightening his grip on his brother's arm as they made their way to the sushi shop their family owned.

Upon entering the shop, it didn't take more than five seconds for their father to notice Tsuna's state, and the man immediately dropped what he was doing and approached his two boys, cleaning his hands on a towel before picking Tsuna up in his arms and fussing over him.

"Are you okay, Tsunayoshi? What happened?"

"S-some boys were b-bullying Tsu-kun!" sobbed the little boy as he hugged his father tightly around the neck.

"Oh, Tsuna," sighed Tsuyoshi, wiping the tears from his son's eyes, and kissing each and every one of his scratches and bruises. "Shh, you'll be fine, okay? Who were the boys that did this to you? I'll go talk to their parents, hm?"

"Forget that, Tsuyoshi-san!" called one of the customers currently in the restaurant, a regular by the name of Takarada, "just tell us where they live! We'll take care of them for you, Tsu-kun!"

"That's right! No one messes with our Tuna!" called another of the customers, a mischievous smile on his face as some of the other customers laughed in agreement. The thing is…they were only half-joking. All the customers at TakeSushi were quite fond of Tsuyoshi's sons and it didn't make them happy when one of them came in looking all beat up.

Tsuna giggled softly at what they were saying while Tsuyoshi's brows furrowed. "Oi! Stop saying such irresponsible things!"

As everyone smiled sheepishly and ducked their heads, Takarada just laughed, saying, "Then if you don't want us to take care of them, why not enroll your boys in karate? They're always welcome at my dojo."

Takarada's family owned a small dojo not too far from TakeSushi, and while he already had quit a few students, he didn't mind taking on two more."

"Ooh! Can we, otou-san?" asked Tsuna, his expression hopeful. "Please? Can we? Pretty please?"

"Yeah! I want to learn Karate!" said Takeshi excitedly, tugging on his father's clothes.

"I'll discuss it with your mother," was all Tsuyoshi would say on the subject.

"Hey, Tsuna, why did you decide to keep Sawada as your last name? Don't you want to be a Yamamoto?"

A ten-year-old Tsuna, who was lying on his stomach, reading a manga, looked up at his brother, who was staring at him with an almost hurt expression from his place in front of the computer, where he had just recently been surfing the net.

The two were in Takeshi's room, and had been hanging out with a companionable silence between them before Takeshi had broken it with his odd question. When their parents had first married, Tsuna was too young to decide which surname he wanted to take on, but last week, on his tenth birthday, he had been deemed old enough to make the decision, and had been asked the question.

After a few minutes of contemplation, Tsuna had finally answered that he wanted to keep the last name Sawada, and while his mother had looked disappointed, his father's expression had been one of a kind of proud understanding, and Tsuna didn't doubt that the man had understood why he'd made the decision.

Takeshi, on the other hand, hadn't been able to understand, though, and it had been bothering him incessantly.

Laying down the WSJ magazine in his hand, Tsuna turned over onto his back, staring up at the ceiling as he answered.

"It's not that I don't want to be a Yamamoto…" he answered, and Takeshi just kept quiet, waiting for him to continue. "It's just that…well, you know how otou-san is always telling us how our heritage is important?"

Takeshi looked at his brother in confusion, as if to ask what that had to do with anything.

"Well," said Tsuna, "even if I am part of the Yamamoto family now, I was still born a Sawada, and that last name is a part of my heritage. Just because my biological father wasn't the best father or husband around doesn't mean that my ancestors were at fault. I'm one of only two Sawada's left from what I know. Don't you think it would be kinda childish to let the Sawada line die out because of something like this?"

There was complete and utter silence for a few moments before Takeshi let out a small chuckle and a wide grin appeared on his face.

"You're amazing, you know that, Tsuna?"

Tsuna just smile in reply, saying, "Anyways, it's not like we need the same last name to be brothers!"

SkyGem: Lol, well there's the fluff-filled first chapter! I hope you like! Next chapter will have the meeting with Reborn, Gokudera's arrival ('cause I just adore him) and, get ready for it, a confrontation with he-who-shall-not-be-named! And no, I don't mean Voldemort. Anyways, please do leave a review and let me know what you thought! Oh, and for those of you that don't know, WSJ stands for Weekly Shounen Jump. Ciao for now!

P.S. Anyone who can guess why I chose this as the title gets virtual hugs and cookies! There are two reasons ^^.

P.P.S. I have a temporary poll up for now! Please vote on it, ne? Then I'll put the current poll back up!
