we know of only one rule by sanji and that is to not hit a woman. nonetheless, he was on the transgender island where this rule is being manipulated by ivankov. fact - sanji hit big mom and she is definitely not a transgender. he can act like that because she wanted to kill the people who are important to him - his biological family. then nonetheless sanji will break another code for the sake of his nakama and captain - the code that prohibits him using his hands, because what can he do as cook without his nakama to cook for them. hence, in the next chapter and the following ones, while confronting the big army for the sake of saving luffy, he will need to use his hands - no question asked. i believe that he has a special gloves or a set of tunfas for the sake of protecting his hands from harm while fighting and not changing his fighting style all of a sudden. I believe that the edge of the tunfa will be made from sea stone. but after he went imprisoned by capon and taken to big mom it's hard to believe that he could hide them so maybe its gloves or arms coated in armament haki and then he uses his palms in a knife position like in karate. because sanji will never hold a kitchen knife for battle. his last rule might be kitchen hell where he sets the environment in flames and his whole body is in diable jumble mode. this would be a great fight to see between sanji and oven where sanji's hit is stronger than oven's hit who could boil the ocean. maybe its a clue for sanji's devil fruit. he won't need the hit hit fruite, he doesn't look and need or act like a zoan and the fire and magma logia fruits are already taken by main characters. which keave us with paramicia. which paramicia can handle his hit? metal will melt snow is out of the question and we are quite out of logia devil fruits then again. so I believe that only the diamond diamond no mi can handle sanji's hit. my theory is that juzu is on the brink of death and his wish is that none of the blackbeard pirates will get his devil fruit. this sets well with zoro not being a liar and saying that he doesn't feel like cutting a diamond. and thus sanji's problem with hardening his body more will be solved as well because we know from the bell dude that by diving deep you can increase the toughness of the body but that its too dangerous and sanji already went outside of the bubble in the fight with kraken and withstood it well and that was really deep and robin mentioned that near the 10,000 m deep sanji will certainly die. so here you have it. * does the fight with p-e-a-r-l rings a bell? the answer is yes - the dimond chase in on the open. what do you guys think?
