- The characters for Kagiyama literally mean "key mountain". Hina could mean either "Bird chick" or "Doll."
- She is sometimes referred to by her official title,「厄神」 or "Yakugami" (meaning "misfortune god"), and has become a nickname of sorts, even though it is official.
- Hina is the leader of the "Nagashi-bina doll army." This refers to a Japanese ritual of transferring one's sins and misfortune to a doll (a Nagashi-bina) and throwing it in a river to be carried away.
- Hina is sometimes paired with Nitori.
