1. Has Zoro mastered enma? As in is he now capable of casually outputting the same amount of haki enma wants like Oden was?
If he has/does it’ll likely mean we’ll see less green smoke that indicates overflowing or over exerting haki. Also it would likely mean he is the king of hell so koh purgatory oni giri will just be called purgatory oni giri without the koh part
2. As for Sanji is he now capable of reaching ifrit jambe levels of heat without the exoskeleton? We know that he definitely did need the exoskeleton to get to that level in wano but if his haki has gotten stronger since then it should definitely be possible. Especially when he gets conquerors he should definitely be able to
It could 100% be a mistake since it’s oda and he does it all the time but he did keep Sanji’s eyebrows normal at one point in elbaf while using ifrit
When it comes to Luffy we know he finally incorporated g4 into his base
