On his face, he had a series of flame-like markings covering the left side of his head and the right side of his neck. Kokushibo gained 6 eyebrowless eyes with red sclera and yellow irises, while his skin became pale and he gained some strange details on his face and body.

He had a number of rather unusual characteristics: he was a tall man, with a pale skin tone and an athletic and muscular build; his hair was long and black with burgundy edges, held in a long ponytail that reached almost to the height of his lower back.

190 centimeters tall.

She wore a kimono with a pattern of violet and black tones with a white haneri (undergarment in a Kimono), a black hakama and a white obi belt.

Despite displaying an outward reserve of character and humility, he was also quite cold: his words could be harsh, especially when reprimanding people. His threats are nothing short of cruel and overwhelmingly serious, and he demands absolute obedience.

Originally, Kokushibo was a human named Michikatsu Tsugikuni who was part of the Demon Extermination Corps alongside his brother Yoriichi Tsukiguni, who is regarded as the creator of the Sun's Breath and a talented hunter swordsman. He harbored enormous resentment and envy towards his younger twin brother, Yoriichi Tsukiguni, due to the natural talent and abilities he had since birth.

One night he came face to face with Muzan Kibutsuji who offered him the chance to become a Demon in exchange for saving his life. Without hesitation, he became a Demon, changing his name to Kokushibo.
