Aoi is tough, uncompromising, strict and serious, displaying an efficient and no-nonsensical attitude nearly at all times. She works as a helper at the Butterfly Mansion, rather than taking to the front lines and fighting demons. Her personality is somewhat similar to that of a younger Shinobu Kocho, being loud, volatile, and open. She often appears angry, generally displaying how she feels very clearly. However, she does occasionally express more tender emotions such as happyness.
