Mio Kofune

Mio Kofune is Ushio's younger sister and a first-year student attending the same high school as her sister. Unlike Ushio, she has black hair. Her tanned skin is due to sun exposure. She is athletically gifted and a member of the swimming club. At the beginning of the story, it is just after her sister's death, but she strives to act cheerfully with her usual smile.
