Arakune is my secondary, so I think it's safe to explain more about his cursing, run away, corner game. This match-up is more on evasive moves and aerials. Cornering Arakune is also a good way to get Arakune in his tracks, because Arakune's health is more viable to damage than other characters.
e.g: Rebel 1, ACTION!
(Arakune facing left)
Arakune either j.->236d->6d, or any other of his curse moves. Since Arakune is a great run-away character, Taokaka can easily avoid being cursed and using her aerials against Arakune. Such as j.6D which brings her closer to Arakune and into a corner. If you are trying to get some damage onto Arakune while he is at the corner, try using 2a,a,a->6a~236a,a,a,a,a,a->6d. I use it a lot against Arakune.
