Similar to the rest of her family, Hinaki had pale skin and large, purple eyes. She had white, shoulder-length hair styled into a blunt bob with bangs and sported a red ribbon on the right side of her head.
Hinaki was usually seen wearing a dark blue kimono decorated with purple flowers and a maroon obi, nearly identical to her twin sister.
Hinaki was usually very quiet, but kind. She loved her father very much and was loyal to him even to the point of dying alongside him.
Nothing much is known about Hinaki, but for sure all we know is that she was always loyal to her father and never would stray away from him.
As an ordinary human, she doesn't possess any additional powers or abilities.
