Looked it up because you gave an untranslated scan for some reason. She's useful for that alone pretty much, that's your entire reason of thinking she'll join? Aside from her being female maybe? She really has no reason to even leave Dressrosa, and having a love interest for Sanji on the ship isn't happening. Can't see her being useful in a 1 on 1 scenario against the Blackbeard Pirates EoS either. Her and Rebecca are really just going to stay with each other and King Riku and Kyros. Why would she leave after they've finally all reunited and can live in peace?
Edit: Well yeah, that's Sanji and he's kind of fallen head over heels for her so I'm not surprised he's asked her to join. I don't even remember another Straw Hat besides Luffy ever asking someone to join the crew before and having them join. I don't really think Sanji's invitation counts.
What does the translation have to do with it? It's her eagle eyes technique, why am I wasting my time with somebody who doesn't know anything? You even think I want her to join!? I wouldn't mind her joining, but I'd prefer it if Bartolomeo or Kin'emon joined. I hate the idea of Rebecca (who's even more pathetic than Nami ffs) joining the crew
She has a function in the crew and fits the usual motif of sad flashback, common enemy when first introduced and designed through the inspiration of another person, viola is designed on Violet Gibson
I literally just said there would be no love interest. Sanji would go after Nami and Robin as well as Viola, making her turn into a stabby little *****. It's funny. You clearly have no sense of humour if you can't imagine any possible running gags from this combination.
EoS!??! There's plenty of time to develop, she's clearly a skilled hand to hand combatant. She's been in a Pirate Crew for 10 years, of course she can fight. Nobody in the crew can do shit against any of the Blackbeard Pirates right now, we haven't even seen her fight properly, you have NO IDEA what she may or may not be capable of. You cannot dismiss a character before they've had a chance.
Why would you stay on the same Island you've lived your entire life when some amazing people give you the opportunity to travel the New World with them? She may have a goal that can only be achieved on the seas. She's already said she wants to leave the Island at some point. I can't find the scan but it's around when she's on horseback with Sanji and tells him about Nami's lightning strike.
Uhm, well: Nami offered Chopper a place before Luffy did and look how that went...
