"30 years ago a large Spacequake occurred in Eurasia. 150 million people died and human life and infrastructure was laid to waste. Spacequakes: A destructive phenomenon of unknown origin. Like the name says, it is a void which destroys everything in and around it. An unexplainable disaster. It has been thirty years after the apocalyptic Spacequake, in the six months that followed smaller scale Spacequakes occurred all over the planet. Japan, the place where I live, also faces similar occurrences. It is known as the South Kanto Void Zone. Twenty five years had passed without anything happening. But suddenly, five years ago, it started again, around the Tenguushi City area. This phenomenon increased by the day, and these occurrences seem to be centred around Japan." — Itsuka Shidou
