I would use her in a WIP story about adventure and war. She'll work with a little companion that was abandoned by their group because they were too weak and she'll raise them to become strong. She was a test subject in the kingdom, to test magic on a human body, unfortunately, all the effects from the magic made her become more magic than human. She was sent to fight for war, but all the different magic in her made her magic too unstable to use. So she was sent out of the kingdom to train until she can actually fight. I'd name her Melody (Since she also loves singing as well).
