So as we know that every Strawhats except Sanji appeared in recent chapters, Chopper, Brook, Robin, Jinbei, Franky, Nami, Usopp, Zoro, Luffy are all presented on screen. But what about Sanji? Usually when Sanji is MIA for a while, it means that Sanji is up to something behind the scene since that’s one of his forte. Now, what can Sanji do?
1. Saving Robin from a potential missing CP0 guy.
There were 3 CP0 guys at the beginning of Wano that negotiates with Orochi, then they appeared again during the raid.
The missing CP0 would be that sunflower hunchback looking guy on the left. So if the hunchback guy is lurking somewhere looking for a perfect opportunity to snatch Robin away from the crew, what else would be a perfect timing for our Mr. Prince to come in and save the day?👀
2. Going to the rooftop to saves Luffy from possible assassination.
Now, the masked CP0 guy seems to be in conflict of whether he should obey the order of the Gorosei to assassinate Luffy or decided to pussy out for the remainder of the arc, but just in case his balls is bigger than we expected and he trying to pull a Flampe on Luffy, obviously one of his two best Wingman won’t let that happens. So if the CP0 guy trying to snipe Luffy somehow, Sanji would jump in while pulling thug life and kicks him out of Wano. And since Sanji have so many extra time in his pocket, he might as well join Luffy to fight Kaido or find the other missing CP0 dude and kicks his ass before he touches Sanji’s sweet Robin. Either way it’s a win win for Sanji.
