She is a Demon Hunter and the Insect Pillar of the Demon Killing Corps. Due to her below-average physical strength, her sword style relies on poisons, high speed/agility, and straight jabs, somewhat resembling fencing.
When she was a child, her mother and father were killed by a demon, which drove her and her older sister, Kanae, to become demon hunters. At some point, her sister was killed by a demon.
Later, it is revealed that the demon who killed her sister was Upper Moon Two, Douma.
