The "Shoutoku Taoist". Stage 6 boss of the 13th Touhou game, Ten Desires, and later a playable character in Hopeless Masquerade, Urban Legend In Limbo and Antinomy of Common Flowers in which she dons a cape.
She wears earmuffs (which are sometimes depicted as headphones), has a pointy hair style, holds a ritual baton, and carries a sword. Japanese fans assume it is 七星剣 (Shichi-sei Ken, Big Dipper Sword), one of Shoutoku Taishi's two famous swords. Its design was influenced by Taoism.
NOTE: Please tag Miko's head accessory as earmuffs unless the artist is intentionally trying to depict them as headphones.
