Sumire Byoubugaura
Age: 16
Sumire is an Oni and Homare's older sister. She's best known for being pretty protective of her younger brother, though the two have that typical sibling dynamic where they bicker as much as they look out for each other. As an Oni, she's got the supernatural strength and heritage that comes with the territory, which probably comes in handy when keeping Homare in line.
