(This is based off the story from sakurademonalchemist: Cloudy, with a Chance of Freedom)

But when Yuni had sent his soul back, it went farther then the Little Arcobaleno Sky had probably intended because he was back into his eight year old body as Harry Potter.

Now back in the past, he is determined to change things for the better and so he slips back into a role that he had given up when became Skull de Mort, that role was Harry Potter. He never expected that he would end up running into the Arcobaleno before they were known as great but of course some bonds once forged can't be broken so easily. And he finds that it wasn't Luce that was the True Sky of the Arcobaleno but him.

9. The Sawada Siblings of Vongola

In this universe, Iemitsu and Nana have three sons instead of only child in almost all universes. Unlike the universes with Tsuna having a sibling, he isn't abused, neglected, abandoned and bully but is loved and protected by them as they are possessive and protective over him. But like in almost all of the multiverses, little Tsuna Sawada was sealed because of Iemitsu and Timoteo. But unlike in the other multiverses, by sealing his flames it had some unknown consequences that neither Iemitsu or Timoteo knew.

When Iemitsu leaves to go back to Italy with his boss but before he does, he talks to his wife into let him take their oldest child, Felix Sawada. Iemitsu wanted to raise him in Italy as an heir to the Vongola, thinking that like his little brother, he too has Sky Flames. Felix isn't happy that he is leaving Namimori to go to Italy with his deadbeat of a father and leaving his two little brothers behind. He knew that his youngest brother was hurt and that it was both the fault of his father and that old man that he brought.

Now nine years later Felix is coming home but he isn't coming alone as Reborn is also tagging alone since he was sent by the Ninth to train the youngest Sawada son to be the next Vongola Boss.

Felix Sawada: He is the oldest of the Sawada Siblings as he is three years older then the twins and he is protective of his brothers, more so with Tsuna. He hates his father, Timoteo and the Ninth Generation after the first two had hurt his youngest brother when they sealed his Sky Flames just after activating them. He was taken to Italy by Iemitsu to be trained to be an heir for the Vongola if anything happened Nono's sons and because they thought he would have Sky Flames like his youngest brother did before they seal those away.

Arashi Sawada: He is the second oldest of the Sawada and the older twin brother of Tsuna. He hates his sperm donor after he had that weird old man do something to Tsuna and that hurt his little brother when they took his pretty fire away, even more so when he took Felix with him when they had left. Arashi grew up to be very close to Tsuna as they grew up, he grew up being protective and possessive over his twin. It was no surprise when he grew feelings for his brother, feeling that you weren't supposed to have for your sibling.
