For me I think it's zoro BTW, I don't know if i would call it respect, but i think that robin values luffy alot more than others.
What about uAttachment 11214
Yup i do agree with you ! Zoro really does respect him a lot even through idiotic action he does (which makes him cool xD) but overall the entire Crew is totally all for Luffy as a captain. They won't stay for him if they don't right ? That's the best thing about SH pirates
