The future. In Tokyo, people live side by side with bio-robots, animal imitations, and silicone trees. Nature is dying, while the country’s power—democratic technocracy—is torn apart by corpocrats and totalitarians. Order is maintained by yakuza clans. One of their members becomes a victim of a political game and ends up in a corrective prison. After his mind is put through a series of rehabilitation programs and he returns to society, the clan disowns its yakuza member. Now he is on his own.
