Yamato was, without question, a true oddball of a woman.
Even in the One Piece World, where oddballs were as common as hairs on an ox, she could still compete for the title of oddest of them all.
As Kaido's daughter, it could be said she had been born standing at the position closest to the peak of the world. Kaido could not exactly be called especially good to her, but he had given her everything she was supposed to have. At the very least, he had not been like Garp, directly tossing his grandson to a mountain bandit to raise, then using all kinds of methods that looked more like murder than training to temper her.
But!
Even so, the strangest thing still happened.
More than ten years ago, Yamato, who was not yet ten, witnessed Kaido's execution of Kozuki Oden and was conquered by the bold, heroic spirit the man displayed.
Immediately after that, as if by heaven's will, she picked up Kozuki Oden's logbook and gained an even more complete understanding of his thoughts from it.
Then the most ridiculous thing happened—ever since then, Yamato, this daughter of Kaido, had actually become Kozuki Oden's most loyal and fanatical worshiper. She even took Kozuki Oden's name as her own, made it her mission to drive Kaido out of Wano Country, and began opposing her own father at every turn.
In the end, Kaido, annoyed beyond endurance, half-imprisoned her on Onigashima.
To be fair, after Araki learned everything Kozuki Oden had done, his only thought was—was this guy a damn idiot?
He had clearly boarded Whitebeard's and Roger's ships one after another, and powerful friends of his were spread all across the seas...
But when Wano Country suffered under Kaido's oppression, he had never once thought of seeking reinforcements
