摘自本作简介中该角色的段落

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. [Based on the English translation of her unlockable profile.]
