Deceive others and seize their wealth! A psychological battle of wits where you either trick or get tricked. You will spend one month in a Western-style mansion on a deserted island with fellow liars. Among the five participants, who will be the one laughing at the end!?

Every participant starts with 10,000,000 yen. After one month, the individual with the most money will be granted the right to have any one wish fulfilled. "Games" involving wagers will be held periodically. The content of these games varies widely, including gambling, party games, and sports. There is a tacit understanding throughout all games that "players may take any action they see fit, except for those explicitly forbidden by the Secretariat." Consequently, even if victory is achieved through lies, manipulation, threats, cheating, or foul play, it will be treated as a valid result as long as it does not violate the Secretariat's prohibitions. Participants may also borrow money from the Secretariat. While there is no limit to borrowing, those who remain in debt to the Secretariat after one month will face collection. The Secretariat will use any means necessary for collection.
