The objective of the first round is to steal the 100 million yen that is issued to her opponent, Kazuo Fujisawa, a former teacher of hers, who easily deceives her. Before the round ends, she comes across Shinichi Akiyama, a genius swindler, who helps her to succeed winning the first round. However, after the first round, a second round of Liar Game awaits them.

The second round of the Liar Game is taken place in a mansion. The 22 players who won the first round are given a jewel worth 100 million yen each as "Game Money" as they compete in a game. The 22 players vote either "Yes" or "No" when asked a random question. The minority of the result survives and the majority leaves with a debt, 100 million yen. The final person gets the 2,100 million yen, 2,200 million yen minus his or her 100 million yen, as the prize. Akiyama has entered and then win the game and decided to split the prize money so that Nao and the people they have teamed up with could pay their debt. Akiyama then decides to proceed to the next round without "Dropping Out".
