In a dystopian future, Kansai, Japan, is a cyberpunk metropolis divided into strict social hierarchies and governed by oppressive surveillance. The city is plagued by a class of dangerous criminals known as Akudama, who are hunted by the authorities. The narrative begins when an ordinary young woman, mistakenly identified as an Akudama, is drawn into a high-stakes heist orchestrated by a group of notorious criminals. Each Akudama specializes in a particular skill, such as hacking, combat, or assassination, and they are brought together by a mysterious client for a mission to steal a valuable package from a heavily guarded train.

The group includes Cutthroat, a bloodthirsty killer; Brawler, a physically imposing fighter; Hacker, a tech-savvy expert; Doctor, a deranged medical professional; Courier, a stoic delivery specialist; and Hoodlum, a petty thief. The young woman, later nicknamed Swindler, must navigate the dangerous dynamics of the group while concealing her lack of criminal expertise. As the heist unfolds, the mission grows increasingly complex, revealing deeper layers of conspiracy involving the government, the Akudama, and the true nature of the package they are tasked to steal.

The story explores themes of morality, identity, and survival in a world where the line between right and wrong is blurred. The characters’ motivations and backstories are gradually revealed, adding depth to their interactions and decisions. The narrative builds toward a climactic confrontation that challenges the characters’ perceptions of freedom and justice, culminating in a resolution that leaves a lasting impact on the dystopian world of Kansai. The series balances action, suspense, and character-driven drama, delivering a tightly paced story with a distinct cyberpunk aesthetic.
