Kanao Tsuyuri

When first introduced, Kanao is quiet and unable to make decisions for herself after abuse in her past, so Kanae gives her a coin to flip whenever she cannot choose a path. Tanjiro later helps her overcome that indecisiveness and grow more confident. Kanao and Tanjiro eventually marry and start a family, with Kanata Kamado and Sumihiko Kamado among their great-great-grandchildren.
