To exact revenge, the Liar Game office is revived. The target is only one person – Shinichi Akiyama (Shota Matsuda). Because of new heroine Shinomiya (Mikako Tabe), Shinichi, who kept refusing to take part in the game, finds himself in the game. Along with Akiyama, there’s 19 other players competing for the prize of 2 billion yen. Omega (Makiko Esumi), who revived the game, plays the game at the Liar Game office with Alice (Mana Ashida). Alice sets up the game, chooses the players and sets the traps.

Members of SWORD win against Wangan Rengogun, which is led by Kohaku (Akira). The city becomes peaceful again. Nevertheless, the most brutal gangs, Doubt and Prison Gang, appear. They try to dominate the area controlled by SWORD.
