Because of Hunter Relax's similarity to void, and the fact that it's one of the 2 newest colors made it's a very popular item, therefore it was sold out very quickly. Now, of course, it's being sold for a much higher price then it is priced in the ToriShop. I'm afraid you'll have to save up some more tc (30-75k if I'm correct) or wait a couple months if you want a Hunter Relax.
