Prologue
It was peaceful before it happened. That day would be forever engraved to his memory. They were just sleeping when it suddenly happened. They were aware of it but many years out of the battlefield made their skills rusty. His parents protected him at the cost of their lives, when the assassin made to a move to kill him just before the assassin lost consciousness with a pretty big gash at his back and died, it all happened all too fast. Fūma Tsunayoshi was just 6 at the time. It was hard but his father's last words to him helped him move on and kept him from turning insane with grief.
"Don't forget the training we gave you and grow stronger. Don't live for revenge and find something to protect. Go to Namimori and start your new life there. You can't isolate yourself forever y'know, have some friends, ne?
"Live for us, Tsunayoshi, me and kaa-san are dying but we made preparations if this would happen, I know you're a smart child and you will know where to find it," said his father, Fūma Kazuhiko, smiling as though he wasn't bleeding to death.
"We love you very much, and remember what I said, ok?," Tsuna nodded tearfully, which wasn't often since he usually hid his emotions behind a mask.
After that, they stopped breathing and their heart stopped beating. Tsuna cried so much that night that his eyes were sore and red. The police arrived half an hour later to witness this scene when they noticed some crying. They saluted the dead and carried them to the hospital for an autopsy but they found nothing in their investigation. A funeral was held for the Fūma couple's death. Many of his relatives attended to comfort him and pay their respects.
After his parents funeral, the boy suddenly vanished from the house with some belongings.
He was later found in Namimori living alone.
Having learned about the mafia through hacking, something his parents helped him in. With that information, he trained himself to be an assassin, a hitman, and a hacker and rose through the ranks with speed unheard of for several decades. He turned famous and was known as La Campana Stoico because all his victims heard before he struck was a soft chime of a bell charm and magnificent glowing stoic orange eyes.
For 10 years this continued until he was rumored to be on par with Reborn, the Number One Hitman in the World. While in the day he was an average third-year, classmates with Ryohei Sasagawa, genius in disguise and admired by the student body as the school's resident 'Ice Prince' due to his handsome face and his stoic personality.
Everything was normal (as normal Namimori can be) until a certain hitman baby was given a mission by Vongola Nono for training the next Vongola Boss, Sawada Ietsuna to a reliable boss.
