Independent of her desire to assist Luffy, Yamato wants to face Kaido on her own:
Luffy asks Yamato if she really wants to fight on their side, that doing so will mean seeing him whoop Kaido. Yamato asserts that she wishes she could do it herself. She states that Kaido has beaten her several times since childhood and ensured that she always paid the price for challenging him:
She speaks fondly and approvingly of Ace (a man who came to kill her father). He's the only one she's called friend:
She tells Luffy to hurry that they need to help finish Kaido off:
When the Beast Pirates try to recruit her to assist them, she states that she's not on their side anymore. Without remorse, she declares "
Let my Father die":
When Luffy says that he didn't come to beat Kaido, she questions him:
She had offered her assistance to Luffy under the impression that he came to defeat Kaido, declaring that she will fulfil Oden's unfinished will to open up Wano:
She expresses worry for Luffy and declares that she wants a chance to beat Kaido as well:
I'm not convinced. There is nothing — and I mean
nothing at all — suggesting that Yamato will fight Jack.
