Shinobu Kocho is a major supporting character of Demon Slayer: Kimetsu no Yaiba. She is a Demon Slayer of the Demon Slayer Corps and the current Insect Hashira (蟲むし柱ばしら, Mushi Bashira?). She is odd, always smiling, and incredibly smart, able to resolve most situations with just an initial glance. Expert in medicine, and the caretaker of the butterfly mansion. Don't waste her time, however. She's secretly got quite a temper.
