When we first see the aura the first thing that big mom and kaido notice is how enma is far from normal. With kaido legit saying he can sense Oden's presence within it
Starts off with light aura around zoro
Develops dark aura around enma
Attack seems to be way bigger than the one done against king
Kaido comments on the strange haki when he noticed it and how enma has to be odens sword after it cut him
Against king
We see the same light aura around zoro but no dark aura around enna
With tatsumaki not seeming as big as before
When zoro finally used ashura against kaido he actually didn't have the dark aura but instead had a lighter aura surrounding it. It also being the one time kaido only acknowledged zoro and zoro alone not oden/enma
We know for a fact that enma is currently still hold odens will (maybe till zoro fully conquerors it and make it only his own)
Even currently with enma/oden reacting to hiyori's music and something goin on with it. Making even more sense with how oden loved it and enma supposed to be hiyori's rightful sword before she gave it to zoro
