The Liar Game office has been reactivated with the sole purpose of seeking vengeance against Shinichi Akiyama, portrayed by Shota Matsuda. Despite his initial reluctance to join, Shinichi is drawn into the game due to the involvement of a new protagonist, Shinomiya, played by Mikako Tabe. He joins 19 other participants in a competition for a grand prize of 2 billion yen. The mastermind behind the game’s revival, Omega, played by Makiko Esumi, orchestrates the events alongside Alice, portrayed by Mana Ashida. Alice is responsible for designing the game, selecting the participants, and setting the traps.
