Background

Her eyesight is unusually sharp, which makes her a gifted reader of an opponent in battle. A hard childhood left her so emotionally closed off that she let a coin toss make her decisions, until time with Tanjiro taught her to act on her own wishes. She is key to the defeat of Doma, the Upper Rank who killed both Kanae and Shinobu. Once the Corps is disbanded she becomes a doctor and later marries Tanjiro.
