Yamato is a major character of One Piece Wano Country Arc. Yamato is the daughter of the Yonko, Kaido. Yamato idolized Kozuki Oden since she was 8 years old but was abused by Kaido. Due to her declaration, she would become the 11th member of the Straw Hat Pirates.


In Yamato's childhood, Yamato idolized Kozuki Oden and wanted to become like him. However, this admiration can cause brief episodes of delusion by mistaking herself for the actual samurai and creeping out others.

Yamato holds a strong particular hatred towards her father, Kaido for his abusive treatment and placing explosive armbands on her. Yamato went as far as disowning him as a parent after witnessing his armbands exploded. After Kaido betrayed Orochi, Yamato even refused to become the next shogun of Wano Country. Her new hatred towards Kaido was so strong that she doesn't care if Kaido dies.

When Yamato met Ace, she wanted to go out to the sea as a pirate but couldn't due to the explosive armbands Kaido placed on her. Therefore, Yamato was awaiting the day to meet Ace's brother Luffy for a long time and also wants to join his crew. In her confrontation towards her estranged father, she eventually declared to Kaido that she is leaving to the sea with Luffy.

Like Trafalgar D. Water Law, Yamato is very sensitive when Luffy called her Yama-O.


Yamato has immense physical strength resembling to her father when he defeated Ulti with little efforts. Despite Yamato's large size, she has immense speed and ran away from Ulti and Page One while carrying Luffy too.

Like her father, Yamato's weapon is a Kanabo mace. While Kaido's mace is heavily spiked, Yamato's mace is studded.

Yamato's attack are similar to Kaido such as Raimei Hakke. While Kaido used it with one hand, Yamato used with both of her hands. According to Ulti, she named it as Raimei Yonke.


Yamato can use Busoshoku Haki, as evidenced by her imbuing her hand and kanabou with it while preparing to attack Hatcha, resulting in a lightning-like effect. Yamato can use this Haki to an advanced degree, being capable of projecting it a great distance forward and hitting faraway opponents with tremendous force with a simple kanabou swing. And was able to hurt Portgas D. Ace
