Super Dimension Game Neptune has a costume system, equipped items change Neptune’s looks. The picture above shows her as a maid.
Pictures below (from top left to right) are examples of elemental outfits such as: blaze, ground, and cold. Each of these get ups also alter Neptune’s parameters. A full set of cold gear boosts her cold attribute to 100%, but ground becomes –50%. It appears players can mix and match, so you can give Neptune a non-elemental maid outfit and rock shoes.
