I usually go for zoning after a curse, trying to get a re-curse (or combo into re-curse) in. From my experience, you do not have to worry about getting close and personal during curse since that is basically what your opponent wants to do in an attempt to get rid of it. Try to make his way towards you as hazardous as possible. Just be cautious if you are facing characters like Ratchel and V-13 (or if you are fighting a mirror-match) since they can hit you out the blue from pretty much any distance, and you should be doing okay. But even if you are zoning most of the time, you can still go "all out" once in a while and attempt to throw your opponent off their guard and break their "groove".
But play however you want to... most of Arakune’s attacks work great both when used on the offensive and the defensive, plus his mobility (transports, drops, fake-outs, etc.).
