She really warmed up to me in the past couple of chapters. I've gone from thinking Yamato will probably join the crew (but mainly feeling ambivalent about that possibility) to actively wanting her to join the crew. I'm very excited for her character arc and cautiously optimistic that Oda will do her justice.
Luffy is not alone on that rooftop. He has four other supernova to assist him against the Yonkou. Luffy does not need to be strong enough to individually take down the Yonkou as he's not fighting alone.
I don't understand the argument for Yamato not joining, could you please explain it?
I think after overcome yonko arc, next is the end to find one piece & fight the world government that hiding history with the cellestial dragon..
Then, Yamato will be straw hat ally as new beast pirates representative (post kaido)..
Katakuri will be straw hat ally as new big mom family / sweet pirates..
luffy will be 'the strongest commander: like gol d roger
zoro 2nd strongest 'vice commander swordsman' will be like Rayleigh..
Jinbe the 3rd strongest yet experienced also as 'helmsman'
Sanji the 4th strongest also as 'cook' & brought vinsmoke
Franky repairman
Brook musician
Chopper doctor
Robin translator
Nami navigator
Seems no role fits for yamato in straw hat crew..
Yamato Also not fit as an fleet members..
So it will be more fit to be yonko kids (katakuri, yamato, weevil???) Allies..
Cavendish, bartolomeo etc will be Straw hat fleet for filler to fight marine fodders vice admiral etc..
Another straw hat allies is country / races.. Like alabasta vivi, wano samurai, minks, fishmen, giants?, etc
