Nao Kanzaki is honest to a fault. Uncorrupted and virtuous, Nao is the perfect target for a large-scale scheme—the so-called Liar Game.

In the Liar Game, participants are expected and required to deceive, manipulate, and betray or be buried in lifelong debt. Yet Nao, with the help of Akiyama's genius, is determined to beat the game without abandoning her morals and prove that generosity and sincerity will always prevail.
