Thrown away by a couple and their son, a little girl is adopted by one certain Vindice. The girl grows up around different people only for them to be taken away from her. From there on, everything starts to change and grow. Time passes and things go downhill but that isn't the end; it never is. Fem27. Part Two is out!

Tsuna has an older brother who became Vongola Decimo while he was neglected and bullied. All he wanted is a little attention and a smile from his mom. And when a mysterious stranger's voice appeared in his head one day, he finally got his wish. But he's starting to think that's he's getting too much attention... (hiatus/rewrite)

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?

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.

Semi-AU. Tsuna is not Vongola Decimo, but Vongola Primo says otherwise. He and the rest of the first generation train Tsuna to take his rightful place as Vongola Decimo, and to help find Tsuna's guardians.

Sawada Tsunayoshi found out that Reborn, the world's no.1 hitman would train his younger twin to be the Vongola Decimo but before the poor baby could even start tutoring the younger Sawada, Tsuna informed that he's the world's greatest hacker going by the name of Cielo who showed up mysteriously 5 years ago that saved a variety of Famiglias in a crisis.

sawada tsunayuki is the little sister of the vongola decimo candidate Sawada natsume. Their father, took natsume to italy for 8 years. after all those years, tsunayuki became a famous hacker, good friends with varia and the cloud guardian. And in good terms with the vindice. But one day, Reborn came to her live.18FEM!27. OOC-ness. UPDATE CH 5: They're finally here!

After being kidnapped on her 3rd birthday, Tsunako was sold to the Estraneo family. She met 4 boys and were all experimented on. One died, 3 escaped, and she was left. Then she met the Bovino boss and was offered to serve the household and his son, Lambo. WARNING! Fem!Tsuna, AU, Pairings undecided.

Tsuna had a traumatic past due to her older brother. She believed that no one will help her if she just wait or ask. Tsuna thought her trouble will end if she's alone. Too bad for her, things are just starting. FemTsuna! Pairing, R27

Tsunako is a girl with a disability. She can't see. While her brother hates her for just being alive and her parents forgot her disappearance; Tsunako changes. Tsunayoshi is to be Vongola Decimo. A few years later she returns... but she isnt what people would expect her to be. Possible paring so that's up for you to decide! FemTsunaxAll. Help me i'm stuck at the moment!

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

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!

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?

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

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!

Despair, Neglect, and Hurt were the words that Sawada Tsunayoshi had to live with his whole life, after all his twin was the one who was showered with love and affection and the one to become Vongola Decimo. Note: No pairings and Dark!Tsuna. Discontinue on this account, Starred will continue it on her account.

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 had a younger twin brother, one that was so much better in everything he did? What if Tsuna hadn't talked in the last five years? Would he still be the Vongola Decimo? ..."I'm glad I decided to check up on you once in a while."

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…

Sawada Tsunayoshi is ordinary. Average. Not at all special in any way. So while having ties to the mafia comes as a surprise to Tsuna, the fact that his younger, more talented, more popular twin brother is chosen as the next Vongola boss doesn't. Not everyone agrees though. After all, what is a world without a proper sky?

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.
