Aqua

Aqua died before she was born. She wanted to live and has trouble accepting the fact she will never get to. A spirit guide took her in as her apprentice almost as soon as she died also. Aqua has earth magic that she would have had if she lived as well as ghost spirit magic. The only way she can interact with the living world is through magic, ironically the only way she can become solid and touch things is if she accepts that she's dead and learns to make the most of it. She doesn't know this and is very sad about not being able to touch anything.
