Karasu Bank is one of Japan's leading banks, boasting the third-highest operating profits in the country. Akira Mitarai is a young employee in his second year at the bank's central branch. His exceptional math skills allow him to instantly spot accounting errors but also make his day-to-day life incredibly boring.

One day, Akira is suddenly transferred to the Special Operations Department's "Appraisal Unit," which he is told is a key department within the bank. Suspicious of his transfer and the unfamiliar department, he is told by his new boss that the bank actually operates a massive underground casino, and that the Appraisal Unit is the department responsible for managing this gambling as well as the gamblers who participate in it. But these gamblers are putting more than just their money on the line, with their very lives serving as collateral to play! Higher risk means higher rewards, but at the top level losing is a death sentence.

Overwhelmed and confused by the strange state of the bank's secret casino, Mitarai meets a mysterious, genius gambler, Shin Mafutsu. Enraptured by Shin's ability to see through his opponents' cheating and emerge victorious, Akira decides to enter the world of life-or-death gambling as Shin's bank representative.

High school student Yasuto Akashi's day begins like any other, but a fight with his best friend—Senichi Aoyama—causes him to skip school. Akashi realizes that he is in the wrong, and so he immediately returns to school. However, instead of open gates, he finds the school completely sealed off from the outside world. Soon after, a giant cat's head blasts through the windows, and Akashi spots Aoyama dressed in a rat costume while drenched in blood.

Only three students manage to leave school alive that day, and similar occurrences are reported throughout the world. Akashi is not free from harm, however, as he is invited to partake in a deadly game whose participants are composed of those who missed school on that fateful day.

When Yuuki wakes up in an unfamiliar manor wearing a maid uniform, she recognizes this as the start of a new death game. After assessing the situation, Yuuki begins to wander before discovering a room with five other maids.

Tasked with navigating a manor filled with countless instruments of murder, Yuuki takes point as the only experienced player in an environment that is designed to actively work against her. Despite this, she is determined to reach the end of the game with as many people as possible—if it coincides with her final goal.
