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 differently colored eyes as a result of a transplant, and thus wears bandages to conceal this fact.Abiru is notable for her incredibly dry, stoic, and unfriendly personality, established early on when she calls Kotonon fat without so much as a change in tone, all of which conceal an immense enthusiasm for animals (or, just their tails) and also for her teacher, Itoshiki Noizumi.
