PROLOGUE (a very short one)...
It's Sunday and the denizens of Akihara Town are soaking in the sun. Children spend their whole day at the playground; teens sit outside near the benches and socialize for hours. You can see fathers playing baseball with their sons. You can see soccer teams in intense battles. Public health is at its all time high; the world seems perfect.
Skip ahead 10 years, it is the year 200X. Though it doesn't look it, it is also a bright Sunday in Akihara Town. The streets are deserted, other than the occasional worker leaving the subway on his way home. The town seems dark and gloomy even at three in the afternoon.
Where has everyone gone? What could cause this change? Network Navigators, net navis for short, are the answer. In a short 10 years, the world has changed from a world of health to an otaku paradise. In this short time, the world has been reversed. Sometime, somewhere, there is someone who works diligently to return the world to its original state. For better, or for worse, it does not matter. For, tonight, Doctor Genki's plan will be put into play.
Lightning strikes as a dark aura floats in to Akihara. Within seconds, the town seems different. The mood has changed, but nobody knows it, nor will they for eight more hours. Eight more hours until the first man wakes up. He will check his PET and will make a discovery that sets off a chain reaction. A chain reaction of occurrences that could very well lead to the end of the network society.
