Mitsuri Kanroji

She is the Love Hashira of the Demon Slayer Corps and a love interest of Obanai Iguro. Unlike most of members of Demon Slayer Corps whose lives were destroyed by Demons and joined the Corps to seek vengeance, Mitsuri entered the Corps to seek a strong man who would accept and marry her, since the Demon Slayer Corps is comprised of many strong men. After training rigorously in a bid to interact with Pillars as much as she could (since Pillars are strongest people in the Corps), she became the Pillar herself.
