She's wearing a necklace with a comma-shaped jewel and holding both a sword and what looks like a round mirror with the reflective surface turned away. Given the Shinto imagery prevalent in the picture, are these the Three Sacred Treasures of Japan (or whatever their official collective name is)? If so, should they be tagged individually and/or collectively? The only one whose name I can consistently remember is Ame-no-Murakumo-no-Tsurugi AKA Kusanagi-no-Tsurugi, the Sword of the Gathering Clouds of Heaven AKA Grasscutter Sword. Additionally, should the character also be tagged as Amaterasu (or whichever Shinto goddess she is intended to represent)?
