In 2001 a global disaster destroyed almost all developed countries. Japan accepted too many refugees, and security in those areas deteriorated immensely. At the same time description of this situation was discovered in Zoroaster prophecy which was followed by the promise of the incoming destruction of the world. Panic intensified even further. By 2003 Japan Government introduced re-differentiation program Ixca. In 2012 most people were beginning to forget the existence of prophecies as apart of previous destruction of industrialized countries nothing happened.

Main character returns from spring camp and believes in tomorrow until the day he meets a girl in rags descending from the mountains. Ixca... prophecy... everyone's wishes... the final act begins. "I'm glad to have met you".
