Harry Potter's life reached its end and turned to dusk. Sawada Tsunayoshi's life has yet to begin. A Sky from Dusk to Dawn. Harry reincarnated as Tsuna.

He had only come here to fulfill a dying wish from a younger version of himself, to take his place in this world as Sawada Tsunayoshi. That had been fine, boredom plaguing him constantly in his long life as nothing seemed to matter anymore. So when Reborn arrives to train him as Vongola Decimo, he ends up with something a little more. Dark!Tsuna, Dark!Universe, slow R27 COMPLETE

Sawada Takeyoshi was a corrupted boy stripped off his sanity ever since he was a little tyke. He will lead Vongola in another bloodshed one that may never revert Vongola back to its original form. But what choice did they have? He's the only heir left...Or is he? Soon, the true sky will be revealed. Ill/Abandoned Tsuna. Strong!Tsuna. MultiFlame!Tsuna. All27. Rated T for swearing

Magic AU. No one would ever guess that 'Dame-Tsuna' is actually the heir to the Vongola Magic Council, the strongest magic family in the world. But when unrest grows in the magic world, Tsuna will need all the help he can get. As Reborn says, it's about time that Tsuna started finding his own Guardians to contract with anyways.
