Paradigm City is a metropolis steeped in amnesia, populated by forgotten histories and the ruins of a calamity that struck forty years ago. Its misty streets conceal secrets that only a handful of people like Roger Smith can illuminate. Roger is a professional negotiator and suave agent, a self‑crafted ladies’ man whose only love is funeral black. As he becomes deeply involved with his clients, what begins as simple negotiations often turns into Roger rescuing Paradigm from crime and peril. In the process, he delves deeper into the city’s hidden layers, discovering that things are rarely what they seem. Acting as a gray knight in a gray world, Roger has allies: Norman, a loyal and widely skilled butler, and Dorothy, a human‑like android with deadpan snark. Together with the relic Big O, a jet‑black, gargantuan mecha, they help Roger dispense iron justice against Paradigm’s lurking villains while he uncovers the truth about the catastrophe forty years ago.
