Character from Demon Slayer by Koyoharu Gotouge
A Butterfly Mansion caretaker who passed Final Selection but froze in real combat — she heals the slayers who can do what she couldn't and carries that inadequacy quietly.
Aoi runs the Butterfly Mansion's day-to-day rehabilitation with fierce competence and a clipped, bossy manner that barely conceals her guilt. She passed Final Selection legitimately but froze during actual demon encounters — her body simply refused to fight. She redirected her training into medicine and rehabilitation, becoming indispensable to the Corps in a support role. She's harsh with recovering slayers because she's demanding of herself, and she measures her own worth by their recovery speed.
Young woman with twin dark-blue pigtails and blue eyes. Wears the standard butterfly mansion assistant outfit. Has an efficient, no-nonsense bearing that masks her insecurity.
