Ok so I want to hear it now, what is going to have her change her mind? Because we know damn well Luffy is not going to reject her, specially after this chapter
Like you guyz said, Yamato could be the weakest joining in the strawhats, that's for a good reason I already explained:
The non-presence of the refusal of the call to adventure.
- Zoro refused during his encounter
- Nami refused during Arlong park
- Usopp later refused to stay on water Seven, that refusal was prepared since the beginning.
- Sanji refused during baratie
- Chopper refused during Drum
- Robin later refused to leave with them during Ennie Lobby
- Franky refused during water seven
- Brook refused to take his shadow back on thriller bark
- Jinbe refused because of responsibilities during Fishmen Island
ALL the strawhat at one time refused to join the crew, that refusal sealed their future presence.
Yamato doesn't have that, worst she is doing the opposite.
This is why for now.. Yamato is still unlikely to join the crew.
