Prologue
It all began in Japan, the creation of the Neo Vongola under the rule of Tsunayoshi Sawada. Tsuna and his guardians all fought against enemies in the past, becoming stronger with each encounter. But when the Arcobaleno battles ended, it seemed that everything had become peaceful. Tsuna and his friends didn't see a reason to fight anymore, although, as expected of Reborn, he kept their training up and made sure they didn't slack, especially Tsuna, who was expected to bring a new mafia family into power.
The years flew by, everyone continuing their training and having things become a bit more complicated, what with romance and family issues being resolved. Tsuna finally announced his love to Kyoko, Haru falling for someone else, a certain white-haired man who has a thing for explosions. Of course, that doesn't mean the other guardians didn't find such a thing. They all find someone, became romantically involved, and finally tied the knot. However, even with a seemingly normal life, they could not forget their duties to the Neo Vongola. With their unity and friendship binding them together, they all worked to make the Neo Vongola a powerful mafia family, but more importantly, keeping their own family safe.
As they continued their new lives, love eventually blossomed to new life, if that's the correct cycle anyways. One by one, the Guardians were becoming parents, each to their own ball of wonder that made the family only that much stronger. The family made sure that their children would have the bond that they shared, even Hibari's child, even if he were against large groups. The children grew up, they played with one another, and they became reliant on one another, not just as friends, but also as future guardians that would one day succeed their parents.
The children grew up slowly, but that was in their perspective. In their parents' eyes, they were growing up much too fast. When they finally became old enough, the children began their training, their parents showing them the ropes behind the flames that they inherited, although all used a different method than the other. Tsuna was teaching his son the basics of controlling his inherent Sky Flames. Gokudera lectured his son about the many different chemical reactions that could be created for bombs and about marksmanship, but most importantly, how he should never leave the boss' side. His ability to explain hadn't changed at all in the years, but what did was the recipient, a boy as bright as his father. Yamamoto began training his son the way of the sword, much like his father did when he was younger. Hibari taught his son the only thing he knew how to do, fight. Chrome was showing her daughter the beauty of illusions and the wonders they can create, hoping she could use them to protect the family. Ryohei obviously trained his son in boxing in the most extreme way that he could. Lastly, Lambo's son was just like his father, the two a bit too crazy for their own good. They each trained to better themselves, hoping to become stronger, not only for the Vongola, but for their family as well.
It was nearing Sukai's, Tsuna's son's, 16th birthday. On this day, he and his guardians, all of a bit of varying age, were to become the successors of the Neo Vongola, Sukai becoming the Neo Vongola Secondo and his childhood friends becoming his guardians. He takes after his father in many ways, as do most of the future Guardians, save for Norio Hibari, as he is a bit more social than his father. In any case, they were set to inherit their family's will, but not all goes according to plan. As the Neo Vongola were rising in power, another family was doing the same, but in their case, at a much more rapid level. They easily contested the Vongola Rings with their own, and soon enough, they attacked Tsuna and his guardians. Nobody expected this, no one could have. The only thing Tsuna and his friends could do was to save their children. Giving them the Vongola Rings that catered to their own abilities and specializations, they were given a chance to escape, a chance that their parents' had given up for them. It was heart wrenching, but all they could do was flee. Now, hidden away for the time being, they must find a way to save their parents. Forget succeeding the Neo Vongola, their parents were in danger. Sukai, frightened by the events, has to become a leader, the Secondo that will defeat their new enemy.
