One afternoon Toki Mishiba receives a mailed note offering him a hefty cash prize for joining a competition. At first he brushes it off, but curiosity wins when he spots the fine print warning that player safety is not assured. His decision to sign up stems from a mix of skepticism and the lure of quick wealth.
Soon after, he encounters Nobuto Nakajou and Kazuo Saitou—his partners in the so‑called Business Game, or simply Biz Game. The trio's uneasy alliance is tested as they navigate the cutthroat competition, and they dub themselves "No Name." With only an insatiable appetite for riches binding them, they plunge into the perilous arena of the Biz Game, battling rival squads over a data disk that holds crucial corporate secrets. Each match demands cunning, strength, and the ability to outmaneuver opponents in order to survive and advance.
