She has large, pale-green eyes with long black eyelashes, a small beauty mark beneath each eye, and light pink lipstick.Hair: Her most defining trait is her thick, waist-length hair that starts pink and naturally fades into a vibrant lime green halfway down. It is styled in three thick braids—two framing her face and one at the back—along with shorter, choppy, voluminous bangs. She wears a customized, modified version of the standard black Demon Slayer Corps uniform. Her jacket is unbuttoned at the chest, and she wears a short, pleated skirt instead of the traditional hakama. Over her uniform, she wears a plain white haori gifted to her by Kyojuro Rengoku. She also sports distinctive lime-green thigh-high striped socks (a gift from Obanai Iguro) and pink-strapped sandals. She looks for the good in everyone and frequently comes up with cute compliments for her fellow Hashira and allies. Mitsuri wears her heart on her sleeve. She was one of the very first Hashira to open her heart to Tanjiro and Nezuko Kamado, treating Nezuko like a beloved younger sister. She maintains an optimistic, enthusiastic attitude that brings a rare warmth to the otherwise grim Demon Slayer Corps. Despite her expressive thoughts, she often gets nervous, blushes, or panics in socially awkward situations. Due to a past rejection regarding her unique pink-and-green hair and superhuman muscle density, she initially felt a lot of self-doubt. She joined the Corps to find a husband stronger than her, but ultimately learned to proudly embrace her true strength. When innocent lives or her friends are threatened, her gentle demeanor vanishes. She fights with terrifying speed, flexibility, and absolute mercilessness against demons.
