Aoi Kanzaki

Aoi Kanzaki is a supporting character of Demon Slayer: Kimetsu no Yaiba and a Demon Slayer of the Demon Slayer Corps. However, she works as a helper at the Butterfly Mansion, rather than taking to the front lines and fighting demons. Aoi is a young girl of average height, with deep blue eyes that fade to a lighter blue at the bottom, along with white rectangular pupils, straight black hair with a parted fringe, and twin-tails. She wears two blue butterfly clips to keep her twin-tails in place. She wears the standard Demon Slayer uniform with the addition of a white nurse dress on top of it, with a blue sash around her waist. Her uniform is tinted slightly blue. She is often seen with a frown on her face. Aoi is tough, uncompromising, strict and serious, displaying an efficient and no-nonsensical attitude nearly at all times. While performing her duties in the Butterfly Mansion, she is effective and pro-active, evident when she quickly demanding a complaining Zenitsu to silence himself and take his medication; Aoi goes so far as to demand he does not complain to her when he does not heal, despite Zenitsu's reluctance due to its bad taste. 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 declaring her enjoyment of the time spent with the trio when they were at the Mansion, looking openly surprised at Tanjiro's reassurance towards her, and bursting into tears when discussing Inosuke's serious injuries. Despite her somewhat gruff demeanor, she is kind and caring, doing her best to help the Demon Slayers that came to the Mansion rehabilitate. Aoi also harbours insecurity over inability to be an effective Demon Slayer, stating that her survival of Final Selection was due to luck and deeming herself a coward for her failure to fight in battle.
