In decade of 2040, the Japanese launched a new way of living. They called it techno house era. The techno house itself consisted of everything automatic, and robot maids. Human alike, these robots looks and acts like human. And as consumptive idiots the world is, they bought the invention.

United States in the other hand, re-build their power. Asians as the world’s brain is the world’s secret that almost everyone knows. As world’s most powerful country, United States bought the techno house’s blueprint and as they said, re-build the ‘army’. Or, in another way means, declare the war of technology.

In decade of 2070, USA proclaimed the cerebro. Something they call robots' brain. This thing makes a robot have the same ability as human already is. They can feel, they have creativity, and other things human never expects another 'living' thing will had.

As time goes by, human can't really living without the help of these robots. But in the other way, human should get away as soon as possible from these robots. Because everything is getting out of control. The number of death with cause of radiation increased in the last 30 years. The air and water pollution is getting out of human's ability to control.

In the new year's eve, year of 2101, the president of USA declaring the shutting down of techno house era. It means, no more robots and automatic living. The mission is to re-build the environment and to decrease the number of death with cause radiation.

But what goes around comes around.

In decade of 2120, the shutting down of techno house era hasn't reach its end. The number of robots suddenly increasing, in comparison robot and human 7:1. The Americans, who invent cerebro, finally know the side effect of cerebro itself.

The cerebros already know how to feel, and how to think. They already know what human will do to them, and how it affects their whole history. The cerebros already learned how to war, how to love, and how to hate.

The cerebros already learned how sweet revenge is.

In exactly April 8th, year of 2142, the war of human and machine officially declared.
