The dark and provocative manga Otonari no Nie by Shinsuke Inue has been adapted into an animation by Studio T-Rex. The result is a tragic and explicit story of coercion, abuse, and betrayal. The protagonist of the tale is Shion, a young child whose father sells her body to other men and exploits her sexually. When her father pushes himself on her even though he knows that Shion has affections for the boy who lives next door and can hear them, the psychological tension reaches a breaking point. As the attack gets more intense, Shion, desperate to protect her secret from the person she likes, strains to suppress her voice, bringing Shinsuke Inue’s intricate artwork and taboo drama to life in a terrifying animated manner.
