As we know, Sanji’s last name is Vinsmoke. Vin is the French term for “Wine”, seeing as Sanji is a high-class cook, and Smoke is pretty self-explanatory. The Vinsmoke family is obviously a noble family because:
1. Sanji is wanted only alive
2. He’s having an arranged marriage, a custom that is practiced by rich and noble families
He is also the youngest of three. I’m assuming his two older siblings are male, and their names are Ichiji and Niji.
Ichi = 1
Ni = 2
San = 3
Now, moving on to Purin. My prediction is that she’s the three-eyed woman on Big Mom’s ship, due to the fact that the “San” in Sanji’s name translates to 3.
Does that mean Sanji and Purin will get married? I highly doubt it, because that means he will have to remain loyal to her, and it’s too early in the series for him to stop flirting with every woman he meets. It would also ruin the adventures of the Straw Hats, because Sanji will either leave for good and live with Purin, or Purin will join the crew. I’m almost certain that Luffy and the others will crash the wedding and save Sanji, sort of like the Strong World scenario with Nami.
That’s all I have to say. What do you guys think? Any feedback is welcome
