Aoi Kanzaki is closely associated with the Butterfly Mansion, where injured Demon Slayer Corps members recover and rebuild strength after missions.

She is helping others stay alive in a world where recovery mistakes can turn into fatal mistakes.

In practice, these statements usually point to the same idea: Aoi is a mid teen Corps member.
