Kasugai Crows

Kasugaigarasu are crows that are used by the Demon Killing Corps primarily for communication.

Description
These crows are special in that they can speak, they are capable of making full sentences, though a very loud and limited version of speech. Most generally look and speak similarly, the exceptions of this is Muichiro's crow, who has feminine eyelashes and can speak normally most of the time, and Zenitsu's Kasugaigarasu, Ukogi, who is a sparrow instead of a crow.
