Yamato

Affiliations: Beast Pirates (former) Ninja-Pirate-Mink-Samurai Alliance (former) Wano Country (current)

Yamato is the rebellious son of Kaidou of the Four Emperors.

Yamato presents himself after the legendary samurai Kouzuki Oden. This profound admiration for the legendary samurai has led to the decision to embody everything related to the samurai to the extent of proclaiming to be a man as well, and hence Yamato is widely referred to as Kaidou's son.
