Higanbana

School Youkai of the 3rd rank, "The Dancing Higanbana". It is said that in the middle of the night a doll dances atop the cabinets of the infirmary. Cursing and injuring others, she is the infirmary's master. She is feared even by other youkai for her brutality. Higanbana spends her days in the infirmary usually eating steamed buns while watching anime late into the night.

However, Marie sees through her demonic persona and the two get along. Higanbana often butts heads with Sumire over prey, so they're rivals in hunting.
