College student Nao Kanzaki has always adhered to her name's meaning: "foolishly honest." However, after opening an unsolicited package containing one hundred million yen, she inadvertently accepts an invitation for the "Liar Game." In this tournament, contestants are encouraged to betray and deceive their opponents to gain a massive amount of cash; conversely, losing will incur a lifetime debt.
