Kaidou: Do you still think that? King. That I'm Joyboy!? Is the world i'm trying to create the world you want!? Worororo
Hold on, is Kaido implying that King Is the one who told him about Joyboy?
it seems like Kaido wanted to change the world and THEN AFTER meeting king, he was told that Joyboy is the one that will change the world… And so Kaido just assumed that he would be Joyboy AFTER king told him about it or something
but years later they kind of both stopped caring about Kaido being Joyboy or not
INTERESTING… Now this does make Lunarians much more interesting if they just casually have void century information
