Yep, she's joining the SHs.
The toy is probably the king too. Pretty touching story, the soldier dedicated his life to Rebecca. I laughed when he beat up both the bullies and boys who liked her. She has a similar background to Robin, only she had someone there for her while Robin had to pretty much raise herself.
Nice little flashback, I enjoyed it.
Did Caribou just beat a member of Kaido's crew ?
Luffy doesn't let food go to waste lol.
