Nice spoilers..
I didn't understand one part though, does yamato use kings haki as a kid?
If so oda should stop this already, i mean it was weird with doflamingo especially now that he looks like a bug compare to yonko, kids shouldn't use CoC as Luffy never did and he would be the strongest king of them all.
If ushimaru is like Zoro's twin then why the heck the fox guy didn't say anything?
Oda needs to explain this somehow..
But i am happy to see Zoro's family nevertheless.
