You also do get an item called a 'Fantasia' mailed to you after paying for a certain length of time on your subscription - a Fantasia allows you to completely change all aspects of your character (except name, guardian and birthdate) once only. Apparently SE will be offering more Fantasias for sale as optional services at a later date on the Mogstation, but at the moment, you can only get one (if you had a character from version 1.0 you're sent a second one though, as a lot of 1.0 players messed up recreating their characters during the transfer).
