Zoro went without saying. It had taken him little more than two years to go from setting sail to becoming a great swordsman. His rate of growth was simply absurd.
If the battles in the later story unfolded quickly enough, Luffy might become the Pirate King in less than a year, and Zoro might well defeat Hawkeye and become the World's Greatest Swordsman at twenty-two.
Twenty-two. What an astonishing number, especially in the Pirate World. That was nowhere near a fighter's strongest years, let alone his prime.
Yet at twenty-two, Zoro already had a chance of taking the title of World's Greatest Swordsman from Hawkeye.
He might not even need to reach twenty-two.
With his strength improving at that rate, it would be incredibly difficult for Kuina to catch up within just ten years of her resurrection. Besides, she would not be trying to surpass a twenty-two-year-old Zoro, but a thirty-two-year-old Zoro.
Honestly, even Su Yunqing felt it was unlikely. That was why she wanted to see the latter scenario instead: just as Zoro was about to face Hawkeye in the battle for the title of World's Greatest Swordsman that he had anticipated and awaited for over a decade, something stirred in his heart, and he spotted Kuina in the crowd.
The look she gave him was incredibly complex. Happiness, dejection, sorrow, regret... all of those emotions were there in her eyes, but above all, there was joy that he had carried their dream forward, and encouragement for him.
That was the scene Su Yunqing imagined. She really did not care nearly as much about anything else.
