At a high school in Tokyo, several of the female students have been moon-lighting as prostitutes. A teacher catches onto this fact and goes about putting an end to it. Things go awry when he discovers he turns into a sex demon with tentacles whenever he gets aroused (huh?). He turns from savior to vilifier, poor prostitute school girls.
Unfortunately the movie Angel of Darkness is not yet available on HBO Max.
