The story takes place at Shishidou Academy, a prestigious school for the wealthy elite. Tomu Shirasagi, a skilled and enigmatic gambler, transfers in from a regular public school and immediately stands out in the rigid, elitist environment. From the moment he arrives, Tomu boldly declares that he will challenge anyone and ultimately bring the entire school to ruin through a series of high-stakes gambling matches. With sharp intelligence and a calm demeanor, Tomu uses a mix of psychological tactics and clever strategies to outplay his opponents. Each match is filled with tension and mystery, leaving others questioning his true intentions and methods—until his tricks are revealed in unexpected ways. As he navigates the academy, Tomu encounters powerful figures such as Mika Shishidou, the brilliant yet arrogant granddaughter of the headmaster, and Abidani, the sadistic dorm supervisor who seeks to drive him out. While the games escalate, fragments of Tomu’s past begin to surface, leading the story into increasingly unpredictable twists.
