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

Complete, semi-AU. There's such a thing as being too much like the 1st generation. Tsuna didn't mean to start a vigilante group, but somehow it happened anyway. Well done, "Neo Primo," well done. (bonus chapter 6-2016)

AU. The virtual reality world of the game "Inheritors of Flame" is a place where you can become anyone. Even Dame-Tsuna can become a strong, confident guild master and gain many close friends. But the game isn't just a game. It could very well hold the key to the secrets of the world, and the fabled Trinisette.

It started with a school trip to Italy. Everything simply went downhill from there.

Since he's done the time traveling thing, it's only fair that Tsuna does the parallel world traveling thing too. At seventeen years of age, Tsuna is thrown into a world where Sawada Tsunayoshi disappeared at the age of seven and ten years down the line the Vongola is still undergoing succession issues. And the Undicesimo is the younger brother Tsuna never had. Sawada Tsunashige.

Dame-Tsuna. No good. Idiot. Stupid. That was all he was. He excelled in nothing, knew nothing- could do nothing. But under that mask was the genius "Hemel" - Said to be the reincarnation of Picasso, a prodigy, a blessing to the human race. If they only knew...

Without an idea how, Tsuna is left in the Italy of 19th Century, in the Vongola Mansion when it was just created. Cut off of contact from his real family, injured and suspected by his own ancestor, he believes his situation can't get any worse. But it does, and he is not the only one to travel back in time. Post! Future-Arc

And before he could say another thing, Tsuna found himself getting slammed before a wall. "So they say, huh, never judge a man by his appearance." AU.
