In the future, space travel has become an inseparable part of human civilization. Humanity spread all over the Milky Way. Most of the problems concerning war, ecological disasters, and others were successfully solved. Human beings have entered an era of peace. But human nature never changes, and most other aspects of human culture haven't either. Since the galaxy became a huge urban playground, a new type of criminals have emerged - interstellar thieves. Piloting their own space ship, they terrorize the galaxy with their cleverly planned tricks. Particularly notorious is a duo of two young and pretty girls, Sati and Shiori... which are the two protagonists of the game.
