OVA
Description
Abiru Kobushi occupies seat 19 in class 2-F. Her most striking feature is the heavy bandages encasing most of her body, including her face, with the amount varying across appearances. Beneath the wrappings lies a skinny, pale physique and black shoulder-length hair usually braided. She possesses heterochromia: her right eye is brown, while her left, concealed by bandages or an eyepatch, received a corneal transplant earlier in life. Kobushi exhibits remarkable physical flexibility, especially in her hip joints, enabling extreme poses without discomfort.

Rumors once circulated among students and teachers that her injuries stemmed from domestic violence by her father. An investigation disproved this, revealing her job at a local zoo. The true cause is her compulsive obsession with animal tails; she deliberately pulls them despite defensive reactions from the animals. This tail-pulling fetish drives her zoo employment. Kobushi maintains an extensive personal collection of mounted animal tails at home, usually claiming they are replicas to visitors. She admits to wearing bandages without injuries to attract attention.

Personality-wise, Kobushi presents a consistently dry, stoic, and unfriendly front, exemplified by blunt comments like calling a classmate fat without tonal shift. Despite this outward apathy, she harbors intense enthusiasm specifically for animal tails and dedicated admiration for her teacher, Nozomu Itoshiki.

Key developments include the early reveal of her tail fetish and the true origin of her injuries, alongside her attempt to attach a tail to Nozomu. Later events explore her corneal transplant, revealing she can see the license plate number of the vehicle that killed the donor. She participated in tracking down a kidnapped Nozomu using her bandages as a clue, briefly kidnapped a classmate she treated as a pet, and stole various "tails" from people. A significant moment occurs when her facial bandages break, offering a glimpse underneath. The origin of her eye transplant is disclosed in the final chapters. Her dream is to travel globally pulling the tail of every animal species, listing the chipmunk, Bengal tiger, and green python as her top three favorites. She aspires to be a veterinarian. After a detoxification process, all her injuries healed temporarily, revealing her uncovered left eye.

Her name is a pun on "kobushi abiru," meaning "to bathe in fists," alluding to the retaliation she receives from animals. Despite ongoing rumors, her father is portrayed as relatively normal within the series context, unaware of or indifferent to her tail-collecting habits.
