Mizuki is a Changeling and a Sorceress. Her natural form is similar to an elven woman, but she is capable of taking other shapes for a period of time now and then, as long as she takes some time to prepare in front of a mirror and practice taking another such shape.

It might be worth noting that she seems to change not only physically when taking another form, but taking on a bit of the quirks of her new shape as well when she changes. These 'masks' of hers serve to let her be what she needs to be.

Yet finding her when she is herself, she can be seen as a pale-skinned beauty of elven lineage, with an agile form free of the ravages of time and steel.
