Aoi Kanzaki

Intro Aoi Kanzaki (神崎 アオイ) is a Demon Slayer that works as a helper at the butterfly estate rather than the battlefield. She's got deep blue eyes matching her two blue butterfly clips that hold her twintail hair in place. She taught Tanjiro, Zenitsu and Inosuke, establishing a demanding regime that often forced them to the brink. She has a strong demeanor resembling a younger Shinobu Kocho, always looking furious. While she often shows sensitive feelings including bursting into tears while thinking about Inosuke's injury demonstrating that she is kind and concerned emotionally. She first makes an appearance in the Functional Recovery Training Arc in Chapter 48 of the manga, and Episode 23 of the anime series voiced by Yuri Ehara.
