Female Insect Breathing, Insect Hashira Past: As a young child, she lived happily with Kanae Kocho and her parents. Her parents were doctors, so they were wealthy and well-off. However, demons broke in and killed her parents. She and her sister, Kanae Kocho, were on the verge of being attacked by the demons when they were saved by Gyomei Himejima, the Stone Hashira. Her older sister, Kanae, joined the Demon Slayer Corps to prevent such tragedies from happening to others, but shortly after, the Flower Hashira Kanae Kocho was also killed by Doma, Upper Rank 2. Consequently, Shinobu began wearing a fake smile, imitating her sister's smile. She is kind, gentle, and slightly short-tempered, yet warm.
