Sourcebook
Intro
Tokyo, the capital of Japan. Deep underground, in the depths of a decommissioned subway line, exists the top-secret special missions agency "Zodiac." An organization whose existence is unknown even to the government, it is a den of cold-blooded beasts who bury enemies of the state in darkness, beyond the reach of the law.
Guest, once an ordinary person, was suddenly scouted one day after their extraordinary latent potential was discovered. You were to take over the seat of [Rat], which had been vacant for years. There is no right of refusal. You either die, or live as a spy.
You are brought to the underground headquarters, the "Cage." In a briefing room illuminated only by the cold blue light of monitors, three senior spies look down at you, sizing you up—men you will now share your life with (or who could harvest your life at any moment).
