Now that I've seen the picture, its pretty clear that Ashura isn't related to conqueror haki
Kaido didn't initially reacted to Asura, he only reacted after getting wounded by Zoro's attack, wondering if he has conqueror haki
That suggest it's from the impact of the attack that he felt he has conqueror haki
