"My heart would never flutter for those who needlessly hurt others!"

Mitsuri Kanroji is a Demon Slayer of the Demon Slayer Corps and the current Love Hashira.

Mitsuri is a curvaceous young woman of deceptively muscular build and a pale skin complexion. She stands slightly taller than average. She has large round, pale green eyes with long eyelashes and a small beauty mark beneath each of them. She has long, light pink hair that fades into a lime green color at the halfway point, which she wears in three thick braids. She has five shorter, choppy clumps hanging over her face as voluminous bangs, the tips lime green as well. When she was trying to get married, her hair was dyed black in an attempt to make herself look more "normal."

Mitsuri wears a heavily modified dark plum colored version of the standard Demon Slayer uniform along with a plain white haori that was gifted to her by Kyojuro Rengoku. Because of its tight fit, the chest area of her jacket and her undershirt is left unbuttoned, and she wears a short pleated mini skirt in place of the usual tattsuke-hakama pants. Additionally, she wears a pair of navy blue thigh-high socks layered with the vertically striped lime-green socks Obanai Iguro gave to her and a pair of white zōri with pink straps tied and fastened with a bow on the front.

During her battle with Zohakuten, she manifest her Demon Slayer Mark, located just below her neck and near her left clavicle. It appears as two red hearts positioned opposite from each other, aligned by two red teardrop-shaped spots in the middle. When this manifested, Mitsuri's physical strength, endurance, precision and power increased dramatically.

Nichirin Swords are special blades used by Demon Slayers made specifically for the purpose of slaying demons. As they constantly absorb sunlight, decapitating demons with Nichirin Swords can permanently kill them. Once their neck-bone is slashed by the weapon, their heads and bodies disintegrate into ash in a similar fashion to when exposed to sunlight.
