Wolf Girl (2005)

When a new, smart and sweet Tokyo girl, Rumiko, starts at a rural elementary school, Akira finds himself smitten, like every other male pupil. Newcomer's popularity is contrasted with the less-tolerant treatment of scruffy Hideko, who, thanks to the arrival of a carnival freak-show in town, is nicknamed the Wolf Girl. Teachers and parents snootily consider the carny off-limits, but Akira is determined to find out whether Hideko really is a wolf girl.

Unfortunately the movie Wolf Girl is not yet available on HBO Max.
