While her original personality was hot-tempered and prone to anger, she has been emulating the personality of her late sister, Kanae, since her death. Appearance: Black hair with purple-dyed tips in a two-tone style. Her hair is semi-long, reaching her collarbones, but looks like a short cut at first glance. A canonical beauty, she wears a purple butterfly ornament on the back of her head.

Breathing Style: Flower Breathing Age: 16 Gender: Female Physicality: 156cm / 46kg Nichirin Sword Color: Light Pink Personality: Originally had a normal personality, but became emotionally unstable and closed off her heart due to a traumatic past, resulting in rare expressions of emotion. Even after Kanae's death, she lived with a cold demeanor without expressing feelings, but began to open up slowly after meeting Tanjiro. Appearance: Straight-cut full bangs. She wears a side ponytail on the right, secured with a pink butterfly ornament that was a keepsake from Shinobu's older sister, Kanae Kocho. Doma Battle: Joins the fight.

Breathing Style: Beast Breathing Age: 15 Gender: Male Physicality: 164cm / 64kg Nichirin Sword Color: Indigo-Gray Personality: Raised like a wild animal in the wilderness. A hot-tempered, simple-minded battle maniac like a predatory beast. He lacks common sense and deep thought, attempting to fight anyone—human or demon—who looks strong. He can be excessively rough, such as using children as stepping stones or speaking informally to everyone, but he is gradually improving after meeting Tanjiro and Zenitsu. Doma Battle: Joins the fight late. Appearance: Two-tone short hair, black with blue-dyed tips, and unique bangs that cross in the center. Green eyes with long eyelashes. His face is so pretty that he could be mistaken for a beautiful girl, creating a stark contrast with his muscular body.

Among demons, he is the most mentally broken. Appearance: Rainbow-colored pupils. Although his clothes are not designed for easy movement, his fit suggests a highly muscular build. He has jagged, shoulder-length white hair tied back.
