At the beginning of your end step, goad each creature your opponents control that's enchanted by an Aura you control. Put a +1/+1 counter on Kaima for each creature goaded this way. (Until your next turn, the goaded creatures attack each combat if able and attack a player other than you if able.)
The set of creatures that are goaded by this ability are locked in when it resolves. A creature becoming enchanted later or an Aura being removed from a creature later won't change whether it is goaded.
