Anomatis

"Anomatis" tells the story of a group of adults who were guilty of accidentally killing a girl in a mannequin factory 20 years ago and were hunted down one by one by a mysterious murderer named "Anomatis". This killer, who wears a white female mask, a black trench coat, and a strange purple goldenrod on his chest, uses his inhuman strength and ruthless efficiency to force the protagonists into desperate situations. When everyone thought this was the revenge of the deceased girl's boyfriend, the truth was revealed in the final basement: the avenger was no one, just an "outsider" who spontaneously explored the truth and decided to carry out lynching.
