Кандзакі Нао

Nao is a stupidly honest girl who sees herself trapped in the Liar Game after finding 100 million yen in a box along with a card. Now, she has to take care of the money for 30 days and try to steal another 100 million from his rival. Nao's father is in the hospital and none of her friends believe her so she contacts Akiyama Shinichi to help her.

As the story goes on she becomes more mature and even gives Akiyama a hand in the game sometimes. She believes that Liar Game is about how much a person can remain honest and plays the games with honesty. She is always concerned about her teammates and opponents and always tries to save them from debts and sometimes in the process sacrificing herself with staying in the game and paying others debts.
