Shinobu Kocho (胡こ蝶ちょう しのぶ Kochō Shinobu?) 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 the Insect Hashira of the Demon Slayer Corps and a supporting character from the Demon Slayer series. She was also the younger sister of Kanae Kochou, and the adoptive older sister of Kanao Tsuyuri.

Shinobu wished that humans and demons could become friends and would sometime offer to befriend her enemies. But that belief was shattered after her older sister Kanae was killed. Unwilling to heed Kanae's dying wish for Shinobu to leave Demon Slayer Corps until she kills the Demon who took Kanae from her, Shinobu had been hunting down Demons, hoping one day she would meet her older sister's killer. Shinobu would still offer Demons forgiveness if they voluntarily undergo excruciating torture engineered by Shinobu herself as a restitution for their crimes (of harming humans).
