Soon, the tasks escalate beyond what the kids are willing to do, and they learn that the cost of failure is death. Will they be able to find a way out of the Ousama Game before more people die, and the living lose their integrity and humanity through their participation in the increasingly horrible daily tasks?

Description:

Under the guise of a "study trip," a group of students from Shiroiwa Junior High School in the fictional town of Shiroiwa (Kagawa Prefecture) are gassed on a bus. They awaken in the Okishima Island School on Okishima, an isolated, evacuated island. They learn that they have been placed in an event called the Program. According to the rules, every year since 1947, 42 third-year high school students are isolated, and each student is required to fight to the death until one student remains. Their movements are tracked by metal collars around their necks, which contain tracking and listening devices; if any student should attempt to escape the Program, or enter declared forbidden zones, a bomb will be detonated in the collar, killing the wearer. If no one dies in a 24 hour time period, there will be no winner and all collars will be detonated simultaneously. (Source: Wikipedia)

Description:

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)
