Kill demon Doma who killed her beloved older sister Kanae
Her family was attacked by demons when she was little. Her and her sister Kanae survived and were rescued by Gyomei. They trained and became demon slayers. Kanae died when Shinobu was 16 to a demon called Doma. Shinobu became a hashira demon slayer after her sister died and smiled no matter what happened since her sister loved her smile so much.
