Tsuna died at the age of five. He led a miserable life because of a brother who was given everything in life, a mother who thought he was useless, and because of a father who was never there. Reborn heads to Namimori to train young Tezuka to become the next Vongola boss, but what happens when a transfer student from Italy arrives who looks just like Sawada Tsunayoshi?

This is a twin fic. Tsuna is the older brother of Ieyoshi. He really isn't surprised when his stronger, better brother is picked to be the Vongola Boss instead of him. After all, no one expected Vongola to handle a weak, petite, mute. But Vongola is going to, from the most unlikeliest of things.

Takeo is the younger twin. He is sporty, popular and intelligent. As far as anyone can tell he is perfect, but behind closed doors, he constantly torments and abuses his older brother, punishing him for any slight: real or imagined. But when the famous hit man, Reborn comes into the picture, secrets and truth come to light as the training of the Vongola Decimo progresses. 8059 1827

Sawada Tsunayuri twin sister to Sawada Hiroyoshi. She was Dame-Tsuna while her twin brother was a football genius and the most wanted boy in school. Life for the younger twin was hell on earth, unless she was back home alone with her mother and cooking or doing household chores. Life has always been predictable, but what if... someone made it UN-predictable. Adopted from KarinMaaka

In a kingdom of corruption, there ruled a young prince who was but fourteen...based on Prince and Maid of Evil by Vocaloid! Fem!tsuna is twins with HDWTsuna, Natsu. For you are the prince and I am the maid, destiny divided this pair of tragic twins...I know it sucks, but please r&r. M for character death

Tsuna gets sent to a parallel world where he has a twin brother Ieyasu is the Vongola 10th. Summary completely sucks. Disclaimer: I own it all! Kufufu! No, just kidding. I own nothing.

AU. Tsuna was raised in the shadow on his twin, a twin himself raised to inherit the throne of the Vongola. But blood is still blood, and when Tsuna decides it's his time to claim back his rightful position, the flame everyone thought was non-existence will burn brighter and deadlier than a supernova.

What if Tsuna's parents abandoned him? What if Xanxus found him and took him in? What if Tsuna had Cloud flames, not Sky flames? What if Tsuna was the Cloud guardian of Varia? [Changed to mystery. Plot will develop!] Will have angst. MAJOR OOC! 4/30/17: THIS IS /NOT/ DISCONTINUED. I WILL UPDATE. Under heavy construction

Tsuna was an Angel, clearly. But then, he had a devil for a brother, a not-so-innocent mother, a hacker influenced split personality disorder and self-imposed muteness. With Reborn discovering his family's dirty little secrets as he trains his brother to be a Vongola and his natural gravitation stealing the loyalty of everyone around him, let's just say, let the badassary begin.

What if Tsuna wasn't the chosen Vongola heir but his twin was? What would become of him? Warnings inside and Rated for future language. Also, credit to 'The Liar Of Truth', who wrote "Sins of Thy Sons", for giving me the idea.

AU. The mafia has chased Tsuna since he was seven. He was told that he is the descendant of Vongola Primo by the Primo himself in a dream. Since that time, Tsuna was trained by Primo through dreams. But, one day, Reborn came and said that Atsuki, Tsuna's younger twin, will be the Tenth. But Primo doesn't agree with that. So, what will happen to them? Chap 1&2 has been edited!

Tsuna was born with a weak heart and his brother Tsutomu was born a year later. Iemitsu then abandones Tsuna, leaving him to die because they only need one Heir for the Vongola family. Never in his dreams would Iemitsu think he had made the worst mistake of his life that one cold October night.

Tsunayoshi Caelum Giglio Nero, is to help Reborn train Ieyasu Iemitsu Sawada, to become the Vongola Decimo. Pairings now decided. Vote over. R27 Strong!Tsuna Adult!Arcobaleno

AU. Tsuna and his brother, Ieyasu are descendants of Giotto, the first boss of Vongola. When a baby hitman named Reborn arrives at their house, Ieyasu is announced as the heir. Will Tsuna have something to say about it, even thought he hasn't spoken for years? or so everyone thinks...And what's this secret he seems to be keeping? Can Reborn help the failing family?

Memory of him as Vongola Decimo is a curse and blessing for Tsuna. He is set to choose his own path, far away from mafia world with his friends. Beside, he has his twin chosen for that throne. Reborn is not sure what to think of Iemitsu's older son. There's something hidden beneath those amber eyes of the charismatic president of Namimori Gakuen. M for violence only

Reborn had never disagreed with any of the ninth's decisions, but when the Vongola boss sent him to Japan to train Sawada Tamaki, the hitman started to think that the ninth had chosen the wrong twin…

Question: What if Tsuna had twin sisters? Answer: His life just got a whole lot more hectic. 18XOC, OCX80. I've finally decided! Yamamoto and Alice are doing to be together! T for cursing.

Sawada Tsunayoshi and Takahashi are twins. But they are total opposites, and when Reborn comes to train the younger twin to become Vongola Decimo, he only has one thing to say:"Nono, I think you chose the wrong twin..." Adult!Reborn Adult!Arcobaleno and maybe a little bit of R27...ENJOY!

"The wish of Sawada tsunayoshi has been approved." "good luck Tsuna." Tsuna gets hit by Lambo's TYL bazooka and is sent somewhere that is not the future. He soon realizes that one thing he has kept saying so many times over has come true. He is no longer the Vongola decimo position candidate, but his your twin is!
