Miya is a member of the Cat People race, identifiable by her cat ears, tail, and distinctive green eyes. She sports orange hair cut to neck length and favors an outfit consisting of a midriff-baring top and a choker. Her speech reflects her heritage, consistently substituting "na" sounds with "nya," "ma" sounds with "mya," and adding "nya" to the end of her sentences. Miya exhibits a cooperative nature, demonstrated when she assisted Ryoma Takebayashi by acting as a lookout during his cleaning of communal toilets. This collaboration positioned her among Ryoma's initial clients.
