I forget that there are Yakuza bosses

i guess they will fight Numbers then . i just feel like they will
Also there are 4 of them while there are 5 Numbers , so not far off in terms of number .
Maybe that big guy from Law's crew ( Jean Bart ) will take on the remaining 1 . Chopper may not be ready to take on a Number yet
( though imo he will take on San Juan Wolf vs Blackbeard Pirates later )
