Didn’t he go white eyes and was sent flying and exploded ? That’s damage in my book
Sanji was even kicking in base
I think the explosion is S Shark hitting something.
The kicking away Sanji has already done in earlier chapters when he booted him away.
The question I'm asking is since we know Nami does superficial or damage that will amount to nothing yet Oda chose to portray it as ultra damaging what's the value in saying Sanji annihilated S Shark with his kick. We need to see how he is in the next chapter to be able to make conclusions.
I want you to ask yourself why Oda would take the time to wank the Seraphim's durability in the chapter and then completely trash it in a couple panels. It's almost certainly leading up to S Shark getting up and bring unharmed.
