He didn't low diff him in the Manga
In the Manga sanji got hit because he got distracted
The anime is just so weird, like they actually tried to do something with king but realized how bad they messed up and didn't have the balls to go through with it
For instance they added sanji's glasses getting broken only for them to reappear later
King only did little to no damage, atleast in the Manga you can argue that king damaged him a bit
In the anime he wasn't even bleeding, his sunglasses weren't broken (technically), his hair wasn't even messed up
So now the anime somehow managed to trash on both king and sanji at the same time
How the hell is that even possible?
