A cute and mysterious girl who wears a floral pattern kimono. Her fox mask has two flowers on its right cheek. Tanjirou noticed that her favorite phrase was "We really like Urokodaki-san."

Opposite to Sabito's aggressive personality, Makomo is patient and kind. She points out to Tanjirou any mistakes in his technique and corrects any bad habits he had unconsciously developed.

Although very close, Makomo and Sabito are not siblings. They were both adopted by Urokodaki as orphans.
