New recruit Suzume joins Kazamatsuri Construction—only to be assigned to the "Corporate Mahjong Hospitality Division"!? In a near-future Japan where gambling mahjong has been legalized, citing studies that it helps prevent dementia, corporate warriors now stake their company’s fortunes on high-stakes mahjong battles! Suzume, fresh out of college, is thrown into this bizarre world where business negotiations are waged not in boardrooms—but at the mahjong table. Based on the short story "The Corporate Mahjong Player" from the novel A Hypothetical Legal Code on Healthy Rebellion in the Reiwa Era and Beyond by Hotate Shinkawa, this is the launch of a near-future business suspense series filled with strategy, satire, and tile-slamming tension!
