Yamato’s Origins and Dream

Yamato was born as Kaido’s child, but after witnessing the execution of Kozuki Oden, they became deeply inspired by Oden’s courage and dreams. From that day forward, Yamato declared themselves as Oden’s reincarnation, adopting Oden’s ideals and even referring to themselves as “Kozuki Oden”.

However, Kaido disapproved of Yamato’s admiration for Oden, imprisoning them for years and attempting to force them into obedience. Despite this, Yamato never lost their belief in Oden’s ideals, secretly reading Oden’s journal and dreaming of sailing the world.

When the Straw Hat Pirates arrived in Wano, Yamato saw Luffy as the man who would fulfill Oden’s dream—defeating Kaido and freeing Wano. They immediately declared their desire to join Luffy’s crew, seeing it as their chance to finally experience the world as Oden once did.
