Hisako is a pale white-skinned onryo (a Japanese spirit that has been pulled from purgatory to take revenge on the living where an onryõ is what can be considered a typical Asian horror film monster) with long black hair that mostly covers her entire face, sunken dark eyes and it can be noted that her mouth grows inhumanly large where it has several rows of razor-sharp teeth inside when she screams.

She wears a tattered rose pink kimono with white flower decals and a red obi sash.
