How old is Straw Hat Boy?

I was sixteen when I went to sea, and I'm only twenty now.

Twenty years old...

Can someone as young as twenty defeat Kaido?

So, from now on, he'll be in charge of the ocean?

Kuro prided himself on his talent, even though many of his sword techniques were copied from the Mumei Kamuyū style with his memories from his previous life. But it was undeniable that his ability to copy them was a kind of talent, and he had never been inferior to anyone in terms of talent in swordsmanship.

He's now the world's greatest swordsman!

Even so, he never thought he could beat Kaido or Charlotte Linlin. They are all at the top level. Why should you think you can just win? They have trained for so many years. Do you think they are just sitting around doing nothing?

Those who lack the most basic reverence for the sea have long since sunk into the ocean and been eaten by sea monsters.

"That's why I asked you to analyze this," Tsuru said. "Don't act rashly, Kuro. Put aside your arrogance and calm down."

Their newly promoted admiral is, of course, arrogant, just like these traditional old-timers in the navy.

He has every right to be arrogant; his strength, his record, and his current status certainly qualify him.

But now, what they want is analysis, not just outright denial.

Kuro stared at the photo on the screen, biting his cigar and taking a deep breath. "My analysis is that it's absolutely impossible. This assessment itself is flawed. CP0's own capabilities are inadequate, so what are they making these random assessments about?"

"But the higher-ups don't see it that way, and..."

Tsuru looked at the straw-hatted figure in the photo who had punched Kaido to the ground, her gaze unreadable.

"The miracles this kid has caused can no longer be described by ordinary standards; we must be on guard."
