In Japan, the largest asset owner and a powerful figure behind the scenes in the political and economic circles, known as the 'God of Money,' secretly gathers a group of young people in the construction of the 'Dream Kingdom' amusement park, inviting them to gamble with a prize of 100 billion yen in a special game that tests intelligence, physical strength, and luck. Those who win will receive 100 billion yen. Young people, eager to turn their lives around by participating in this 'desperate game,' help each other, share joy, and gradually build true friendships. Sometimes it involves psychological warfare at critical moments, and other times it becomes a brutal survival game where they must eliminate partners. The protagonist of the game, Yu Hai Ling, is an informal middle school teacher at a tutoring school in a small town. However, his true identity is that of a 'righteous thief,' an anonymous hero who saves the weak from suffering in modern society. This seemingly impoverished genius gambler, who cares more about helping others win than achieving victory for himself, is about to showcase his skills.
