The year is 2084 and the human race is fighting an alien militia to save the last remnant of civilization. A young heroine named Milly escapes the war and jumps back in time to present-day Japan in an attempt to change history and prevent the demise of her people. Milly's return lands her in the middle of a local crime war between Miyamoto, a street-smart gunman, and Mizoguchi, Japan's crime leader. Milly must coerce Miyamoto to help chase down the extraterrestrial and save the human race. But first Milly must convince Miyamoto she's for real. In the visceral, dark, cold world of the streets, these two fight against the evil and ignorance that will destroy everything.
