As much I have a bit of disdain for Sanji’s character, I want to do a similar thread on Luffy Zoro and Sanji, How Zoro and Sanji display two different versions of masculinity, bushido(asian masculinity) and Sanji being a gentleman (western masculinity) etc. it boils down to what you like most tbh. Still think Zoro is the most important second to Luffy simple by a virtue of being a part of both trios.
