It all started with a crush. He seems to be stronger than he looks like. Then stalking. He unconsciously watch him from afar. Taking in everything, etching it in his mind. Then love. He can't get him out of his mind. He seem to notice everything about him. And he loves him too. Then obsession. His mind is full of him. He became the center of his world. So he planned to make their world. Their own world.

"Reborn please don't let go of me! Please, if I have done anything wrong to you, tell me! You are the only one that I have left! Everyone else left me already! I can't lose you too!" Tsuna said as he held his hand out towards the fedora man. But Reborn only pushed Tsuna away and glared at him. "Let go useless boss. I have found a better sky than you so back off." He said with a glint of disgust can be seen in his eyes. Tsuna was shocked... more like hurt on what his tutor just said. Tears streamed down his face as he clenched his fist, until it turned pale. "I... I understand. I-If that is what you want... I'll let go of you all." The brunet said with a smile... a closed eyes smile. "I will never forget you all... don't forget that... Hayato, Takeshi, Ryohei, Chrome, Mukuro, Lambo, Kyoya and... Renarto." He added as he watched Reborn walk away... He smiled again... That was his last smile... On that day, the sky lost his own willingness to live... lost his reason to live... and on that day... the sky... has been lock on the cage of darkness and loneliness. His fate is so cruel... that even his guardians turn their backs on him... They turned to Vongola Nono's daughter who was found alive... even his father... Why must fate have to be cruel on him?

Right after the moon incident: Tsuna was transferred to Kunugigaoka with the help of his father and Reborn, his brother's (Giotto) tutor because they want him to get better. That's what they said, but the truth is, they just don't want him getting in the way of their work. Tsuna knew they were lying so he just followed them. [FULL SUMMARY INSIDE]

Tsunayoshi was a member of the Sawadas. His family ignore him in order to protect his innocence against the mafia, but because of this, it has driven the family into two. Now that they have lost Tsuna to the Gesso family, they regret everything. Tsunayoshi is an experiment in the Gesso family. He only trust his "brother", Byakuran. Byakuran protected him from the mean white coated men, the only one who showed love to him, and is the only one to show the light in this chaotic world. He will protect his "brother" from anything, even from his real family. Byakuran is the boss of the Gesso family, and the "brother "of his beloved Tsunayoshi. They both are fallen angels, and nobody will take away his Tsunayoshi. Tsuna contains the power to change the world, either good or bad, and someone is determined to use it for evil.... Set in AU and yes....it is yaoi. All x Tsuna. Brotherly love/Byakuran x Tsuna broken/Tsuna Strong/Tsuna hope you like it!

Tsuna's family abonanded him for Ieyasu, his younger brother. he was sold to the mafia and exprimented on. soon he was saved by The Arcobaleno. He returns to namimori 10 years later with the Arcobaleno. ( this is my first fanfic so please be easy on me.)

Tsunayoshi Sawada had been alone ever since he could remember, that is why he would never try to be friends with anyone, they would turn their backs on him just as his blood relatives did, he was certain of it because the first friend he made in elementary had cruelly betrayed and humiliated him. "Family ? I don't remember being part of their family, they are just strangers I lived with since I was little" Tsunayoshi answered blankly and without doubt.

He is mine. No one touches him but me. Those unfortunate souls who dare defy my rule will be subjected to a hell worse than death. He is mine. No one touches him but me. Not even his mother, his pathetic friends and those stupid kids. I will kill them if I must. He is mine. No one can take him away from me. Not even death. If I must, I shall kill Death. I am a deceiver, a liar, a demon. I will walk the six paths of hell again if it's all it takes to claim him again. He is mine. And anyone who comes in between is an enemy. An enemy I am willing to destroy.
