Tsuna had seen many amazing things since his initiation into Vongola; he had seen love and marriage and hate and pain. But to date, there was one thing that gave him the greatest sense of honour in being a boss, and it was something only his guardians could bestow upon him.

Primo looked on at his descendent with pity; part of him as saddened by the fact that this was where his lineage was going to end, and another because he knew the pride a father felt when his first son was born. Deciding it was his duty, Primo gave a helping hand when Iemitsu could not provide what they both needed and desired.

Sequel to 'A father's Pride'; Tsuna wasn't always aware of it, but somewhere inside him he knew it was there. Something warm and soft, if not always really there. He had never had faith in his father, always close to forgetting his face before his sudden and short arrival back in his life; but that was okay, because Tsuna didn't' need a father when he had a wonderful daddy.

AU. No-good Tsuna was all just an act. In reality, Tsuna was a famous mafia hacker hidden by the name Erebus that could bring destruction to all mafia Famiglias. But when a hitman called Reborn appears to train him to be Vongola Tenth, things just got a whole lot more complicated. If his identity is found out, he just might be killed by his own tutor.

What if Tsuna was growing up in a different place? What if he grown up in mafia environment and as the Vongola Decimo since the beginning? This can be considered as AU. More warning inside. Rated T for language and slight violence. Flame aren't welcome.

Everything was normal for Sawada Tsunami, but one day a baby showed up saying that he was going to a be a don. But now his brother,Tsunayoshi, showed up to destroy Vongola and who's Reborn? Why's Hibari with him? What's happening? -Now Ongoing story-

What if Tsuna was smart, like genius hacker smart, but decided to hide it behind an average student exterior. Rating for the fact that this is a Mafia fic and possible dirty language. Rating may go up.

In school, he may be known as Dame-Tsuna, but in Italy, where he spent the first five years of his life and where he spends every summer vacation, he's respected as the future Vongola Decimo. He likes keeping his two lives separate. Too bad Boreen-sensei has other ideas. AU. No pairings.

AU, Earth and Meraviglie are two worlds interconnected by a barrier however it's only known to a selected few. Those that can travel to the other world and have the ability to make pacts with those in the other world are known as Capturers. Tsuna, having that ability, accidentally stumbles across a humanoid man with a fedora hat. Full Summary inside, Arcobaleno27, main R27

Bunch of unconnected stories. #2: Reborn was the one who discovered it-it, what was secretly dubbed as One of The Reason Why Decimo is So Hot. Mentions of All27.

Iemitsu realizes, too little too late, that no matter how much he may brag about his adorable son, he lost the right to call himself a father years ago. And Tsuna, tired of waiting for a dad that would never come home, has already found another father figure in the form of his ghostly ancestor by the name of Giotto. Angst. Giotto/Tsuna father-son fluff. Now a drabble series.

Thirteen years ago, Sawada Natsume was born. Ten years ago, a mysterious brunet showed up at the Sawada family's front door. Now, the two boys live with each other as brothers. When Reborn comes to train Natsume into Vongola Decimo, he wasn't expecting to find two boys, much less one with a secret that goes back 400 years in time. OOC Tsuna.

The Varia finally meet someone who they cannot intimidate when a mission takes an unexpected turn.
