Yeah, sure! Sanji is going to fight the one Gorosei with a sword, who is also arguably the coolest of all Gorosei. As we all know, Oda likes to give the cool swordsman opponents to Sanji!
Man, be fucking happy if he fights ANY Gorosei at this point without getting blink diffed and told to sit down again!
Mars is where zoro is trying to attack the lab
Nasjuro is separate from luffy attacking the pacifista. Potentially going for Bonney next where sanji is
