You seem to be under the impression that Oda has any amount of consistency regarding these things… Let me ask you, what’s the difference between the following things
1. Flame Haki
2. Black Flame Aura haki
3. White Flame aura Haki
4. Aura Smoke Haki
ALL FOUR of the above are before Zoro unlocks CoC
Number 1 has been used like only one another time in Dressrosa
Number 2 was only two times. The Hiryu Kaen and the Dragon Twister both on the roof
number 3 was used only once when Zoro was charging up Ashura
Number 4 was directly stated to be Ryuo and appeared every time Enma was fucking with Zoro
and note that even when Zoro started using KoH, the smoke didn’t even look like Number 4 as well
Do you believe Oda in his mind wants us to think there is some material difference in all 4 above Depictions of what’s directly stated to be COA?
I can do the same for Black lightning and it’s inconsistency with COA and CoC to drive the point across that Oda is just inconsistent
