Kobushi Abiru, student no. 19 of class 2-F who is always wrapped in bandages. Her name is derived from kobushi abiru, meaning "to bathe in fists". People thought that Abiru was injured as a result of domestic violence, but it is revealed that she gets the injuries while working at the local zoo. She also has a tail fetish; all her wounds came from irritated animals as a result of pulling their tails, and she has a collection of mounted (fake) animal tails in her room. She also has heterochromia, but her differently colored eye is usually covered by an eyepatch.
