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.

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.

He would've fallen into depression, had Byakuran and Yuni not decide it would be a fun idea to kick down the Sawada's front door and freeload. ... Wait, what? AU, OOC, Un-Beta'd [discontinued, forgive me]

Reborn never imagined that a simple screw up during a mission would lead him to the weirdest person he had ever met. Now he just needs to make sure that this person doesn't learn about his identity while being in an eight years old body. Boss!Tsuna R27 COMPLETE

Tsuna pouted as his family made fun of his imaginary friend, it wasn't his fault they couldn't see him. It wasn't his fault that they couldn't see the tall man with a fedora that was behind them watching everything with those sharp dangerous looking eyes of his. Fluff mainly. No pairing!

Sawada Giotto, the newly introduced Vongola Decimo has left for Italy in order to train under the Ninth. He would rather go and keep his innocent younger twin, Tsunayoshi, away from the dark world despite his tutor's comments that Tsuna could very well be an asset to Vongola. However, Tsuna and Reborn have other plans, which would have gone well if not for someone's intervention.

Two babies named Reborn and 'Cielo' Sawada suddenly came to the Sawada household to train Takahiro Sawada to be the 10th Vongola boss.
