It's not Sanji I'm afraid of, it's Kizaru.
Well, I wouldn't say "afraid of", more of "afraid for" if that happens.
Because if that really happens the Admiral fandom is basically over.
There's nothing that could happen that could save Kizaru from such an embarrassing moment.
I mean even when Aramaki and Issho got stalled by Morley and Karasu they had the excuse of not being able to go all out in the Holy Land, but Kizaru? He can use a good amount of his arsenal here, yet is still getting stalled by Sanji (hypothetically, I doubt it'll happen).
That's embarrassing bruh...
