March 6, 2035. Motoko Aramaki is a hyper-advanced cyborg, a counter-terrorist net security expert heading the investigative department of the giant multi-national, Poseidon Industrial. Partly transcending the physical world and existing in a virtual world of networks, Motoko is a fusion of multiple entities and identities, deploying remotely controlled prosthetic humanoid surrogates around the globe to solve a series of bizarre crimes.

Meanwhile, Tamaki Tamai, a psychic investigator from the Channeling Agency, has been commissioned to investigate strange changes in the temporal universe, brought about by two forces, one represented by the teachings of a professor named Rahampol, and the other by the complex, evolving Motoko entity.

What unfolds will be all in a day's work... a day that will change everything, forever.
