"Liar Game" is a psychological thriller manga series written and illustrated by Shinobu Kaitani. It was later adapted into an anime television series.

The story revolves around Nao Kanzaki, a young woman who gets involved in the Liar Game, a tournament where players are forced to cheat each other using psychological tactics. The main premise involves a series of games where participants must try to take money from each other while avoiding being cheated themselves.
