Over the course of nine years, Kyros traveled through nearly the entire world. At last, he understood that he had not been wrong back then. What had been wrong was the nation of Dressrosa and the Riku Royal Family that had fostered such a twisted cultural tradition.
Once that realization cleared his mind, the spirit Kyros had suppressed for years was finally set free. His Armament Haki transformed as well, revealing its edge, and he became the first Grand Swordmaster in the history of the Dressrosa Kingdom!
However, although he knew that he had done nothing wrong when he had stood up for justice, King Riku had spared his life back then. Kyros also disliked the New Dressrosa Kingdom, which Doflamingo had taken to the opposite extreme. Thus, he still decided to defeat that utterly wicked "Heavenly Yaksha," rescue his homeland, and repay King Riku for saving his life.
Kyros alone was enough to defeat the "Heavenly Yaksha," Donquixote Doflamingo, whose strength might have reached the peak of B-rank but who only excelled at bullying the weak. Not to mention that he had the aid of Charlotte Amande, another Grand Swordmaster.
Yes, after years of a long-running romance, Charlotte Amande had not only gotten her wish, but had also overcome her race's cruel, bloodthirsty instincts through the power of love. She had finally gained complete control over her strength and likewise stepped into the realm of Grand Swordmasters!
Although her physique was somewhat weak for that level, and she had no Grand Swordmaster seniors of her own race to offer guidance or lessons, forcing her to explore everything alone, Charlotte Amande was likely the weakest Grand Swordmaster in the world at present.
But even the weakest Grand Swordmaster was still a Grand Swordmaster. The bottom of A-rank was still A-rank.
