So all this time he's basically been wasting all his haki for no reason thinking he was using CoA and accidentally leaking CoC.
All this time he was using Enma's power to access CoC because it literally sucks all his haki so he can't hold back nor control it.
King of hell mode is quite literally named after Enma because without Enma he can't use CoC
Now he's trying to access CoC without Enma's power.
Being a zorofan, you should actually read his chapter vs King.
