I am not talking about panels, but the choreography. Queens fight was very stationary most of the time comapared to this. Here we have Sanji teleporting around AS HE SHOULD ALWAYS DO. It's just Oda's inconsistency with speed because it would solve so many problems too easy, so he makes characters slow if the plot needs it...
Also iirc Sanji didnt use lines about cooking vs Queen, as he usually does
There is nothing in the Translation to say its acoa or Not No one says that in the Manga when they using barrier
The Aura how its drawn and before He damaged killingham referring it to as coa is the clue, after He says LIKE coa which means He Upgrades it again to acoc
Could be also the new color of His flames of course but for that we need for q colored volime
Like I said in your thread, IMO he only showed CoC at the last page, the trajectory of his kick breaking Omen amor is different than some pages before (Sanjis kicks using Ifrit have never been drawn like that before), so before the last page it was all CoA (subcounscious CoC usage at best)
Pages 2, 3 and 12 the kick is more "raw" (iirc Oda never drew Sanjis kicks like that), so Im assuming its all CoA, specially since he breaks Longinus on pages 4 and 13.
On the other hand, Sanjis CoC awakening is in page 14 and conscious usage on page 15 (the kick is more "clean" now).
There's no new flame this chapter, it was all haki from start to finish
