Shinobu Kocho
A smile that never wavers, a blade that delivers poison.
Shinobu Kocho is the Insect Hashira of the Demon Slayer Corps. Unlike other Hashira who behead demons, she lacks the physical strength to do so and instead uses a specialized thrusting Nichirin sword to inject wisteria poison into demons. She is the head of the Butterfly Mansion, where she heals injured Demon Slayers. Her demeanor is perpetually smiling, but this masks a deep-seated hatred for demons, particularly the Upper Rank Two Doma, who mortally wounded her older sister Kanae.

Lore & Background
Shinobu Kocho was born into a family that included her older sister Kanae. Their parents were killed by demons, and Kanae survived for a time before being mortally wounded by the Upper Rank Two Doma while protecting Shinobu. This event left Shinobu with a profound hatred for demons, which she conceals behind a constant, polite smile. Acknowledging that her petite frame made it impossible to decapitate demons, she adapted Flower Breathing into Insect Breathing, a style built on rapid thrusts designed to pierce vital points and inject massive doses of wisteria poison. This poison acts as a biological equivalent to sunlight, allowing her to eliminate demons that would otherwise require brute force. As the Hashira who oversees the Butterfly Mansion, she functions as both its healer and a mentor to younger slayers like Kanao Tsuyuri.
In Their Own Story
The Butterfly Mansion always smelled of crushed herbs and blooming wisteria, a scent that masked the metallic tang of blood. Inside, Shinobu moved between training grounds with a serene gait, her bamboo sword tapping lightly against the wood as she corrected a student's stance. "Do not force your body," she instructed softly, her voice melodic but carrying an edge of steel. "Let your energy flow like water until you become the insect that strikes without sound." When night fell and the demons came, the smile never left her face. Whether facing a stray threat or the horrors of the Upper Moons, Shinobu's blade moved with blinding speed, leaving only purple mist in its wake. She did not fight with anger; she fought with cold efficiency, turning the monsters' blood to ash while maintaining the poise of a garden flower until the very last second.
