Mitsuri is a curvaceous young woman of deceptively muscular build and a pale skin complexion. She is called beautiful and charming on multiple occasions.
She stands slightly taller than average. She has large round, pale green eyes with long eyelashes and many notable white sparkles reflecting light off of them, a small beauty mark beneath each of them, and light pink lips. Mitsuri has long and visibly thick sakura 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 version of the standard black Demon Slayer uniform, tinted dark plum in the anime, along with a plain white haori that was gifted to her by Kyojuro Rengoku. While at the Swordsmith Village , Mitsuri wore a kimono with floral designs. 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.
During her and the other remaining Hashira's fight against Muzan , Mitsuri's left and back braids are cut off by Muzan Kibutsuji 's attacks, now shortened to shoulder length, and part of her left ear is also torn at the side. Mitsuri is a very emotional, passionate, and jovial individual who constantly compliments and swoons over her comrades in her head, likely a contributing factor towards her nickname as "the Hashira of Love.
However, despite her gentle and seemingly innocent demeanor, Mitsuri will show no mercy in the face of demons , instead expressing such sentiments with a fierce tone. She showcases a great amount of dedication to the Demon Slayers' cause. Despite being put out of commission by Muzan at an early stage in their battle, she was determined enough to return and fight. Given her desperation for marriage, Mitsuri decided to become a member of the Corps with the purpose of finding a suitable husband stronger than her, a rather difficult task given the astounding level of her physical strength.
