Character Overview
Aoi Kanzaki is a member of the Demon Slayer Corps who resides at the Butterfly Mansion under the guidance of Shinobu Kocho. She passed the Final Selection but chose not to become an active Demon Slayer because she believed she lacked the courage needed to fight demons directly.
Despite this decision, Aoi dedicates herself to helping injured swordsmen recover. She supervises medical care, rehabilitation exercises, and daily activities within the mansion.
Aoi has dark blue hair tied into a ponytail, large blue eyes, and wears the standard Demon Slayer Corps uniform beneath a white nurse-style apron. Although she often appears strict or impatient, she genuinely cares about the people she helps.
Her first major appearance comes after the Mount Natagumo Arc, when Tanjiro, Zenitsu Agatsuma, and Inosuke Hashibira are brought to the Butterfly Mansion for treatment.

Her notable abilities include:
- Extensive medical knowledge and patient care.
- Rehabilitation training supervision.
