There is a legend that tells of how the world was almost destroyed thousands of years ago by the vampire queen after she unleashed her latent powers. Despite their efforts, the humans were unable to defeat her, and thus resorted to sealing her away until the time came that they would be powerful enough to destroy the seal and kill her. However, the humans are not the only ones after the seal. Having cast aside his kingdom and betraying his own race and the dhampirs (half-vampires), the vampire king is persistantly searching, even to this day, for where his queen has been sealed away so he may break the seal and free her before the humans do. Fearing that once the king and queen are reunited, they shall continue to destroy the world together, the humans and dhampirs hunt the king, using any method possible. (Source: Anime Source)

Wishing she would live up to the ideal, Kanzaki Nao's father named her thusly for “honesty”. Nao has more than lived up to her father's wishes—even exceeding them and earning the label of "a foolishly honest girl". This makes Nao the least qualified candidate for the high stakes 'Liar Game', where winning requires deceiving the opponent out of their money and losing means receiving massive debt. However, that doesn't stop a box containing a hundred million yen in cash and a card informing her of her participation in the game from arriving at her doorstep, nor does it stop her from being promptly tricked out of the entire sum of money. Upon hearing that a genius swindler, responsible for the bankruptcy of a major corporation, is being released from jail, Nao goes to the swindler, Shinichi Akiyama, to enlist his help. With that, the two are drawn into the dark, greed-filled, and deceptive world of the Liar Game. (Source: MAL Rewrite)
