Me: This is just a little something that I kind of want to work on since I love both Yona of the Dawn, and Katekyo Hitman Reborn. So I don't own either of these anime, but I own my OCs along with the plot of this story itself. So without further delay here's the prologue.
Prologue
The Hiryuu Clan was once a proud and revered clan of ninjas. The skills these men and women possessed were sought by many and rivalled by none. But as all things do the clan lost its standing and slowly faded out of knowledge. Time passed, and the Hiryuu ninja continued in their ways, but as times became more modern so did they. Technology opened more doors for them, and their old skills were nearly forgotten. They took to things like petty thievery, and drug dealing. Those who could still remember the teachings of the old ways were deeply grieved by this turn, and grew sorrowful.
But after a time things changed again. A young man drew those who had faltered back and retaught the ancient ways of their ancestors. The Hiryuu were a proud clan once again, but more than that they had become a family. The Hiryuu family burst into Japan's modern time as a part of the Yakuza, though they only took jobs and did what they knew to be right. The man who had reunited the dying clan and gave them a new purpose married and had two sons. His eldest; many thought would be given the position that his father held. But when the time came to announce his successor the Hiryuu's savior gave the position to his youngest son Il.
Yuhon the eldest simply shrugged it off, and went about his duties efficiently and with no regrets. He vowed to protect and serve his younger brother throughout the rest of his life. Both sons married and had families of their own. Yuhon was blessed with a son whom he named Su-won, while Il was given a daughter whom he cherished. Her name… Yona. A loyal Hiryuu ninja, as they still called themselves, named Mun-deok, had found an orphaned boy. He took the child in as his own and named him Hak. The boy grew close to Su-won and Yona, and the three became great friends.
But tragedy struck when Yona's mother was killed by a rival Yakuza, and not long after Yuhon was also killed. Il grieved for many days after his wife's passing, and Yona as well mourned the loss of her mother. Su-won was the one who comforted his cousin, and helped her through everything. When Yona turned thirteen Il announced that she would be his successor, though many wondered what use she'd be to their family. But before they could even find out Yona and Hak went missing, and Il was found dead. Su-won was the only remaining heir, and was made Il's successor though the Hiryuu Family searched for the crimson haired girl and the Lightning Beast that accompanied her.
But their searches proved futile, and Yona and Hak were declared dead. But still Yona's cousin, Su-won didn't believe it and was wary. But unless Yona found more help she and Hak stood no chance against the force he had at his command. She needed her guardians if she were still alive, but he doubted that she'd ever find them. But as they say 'the world works in mysterious ways', and that was to be proven quite true.
