Kasugai Crows (鎹かすがい鴉がらす Kasugai Garasu?) are crows used by the Demon Slayer Corps, primarily for communication. Each of them is assigned to a member of the Demon Slayer Corps. They deliver missions to their designated members.
These crows have the particularity of being able to speak complete sentences, although their speech is very loud and limited. Most of them have a similar appearance and language, except for Muichiro Tokito’s crow, who has female eyelashes and can speak normally most of the time, and Zenitsu Agatsuma’s Kasugai crow, Ukogi, who is actually a sparrow and not a crow and can’t really talk.
