Hero Return

In a prosperous city where society is strictly divided into classes, people live in relative peace. Yet not long ago humanity stood on the brink of annihilation because of mysterious monsters. For years they brought destruction and death, and, led by their masters, they had no intention of halting their expansion. Governments around the world admitted they were powerless, and the whole planet plunged into chaos as a wave of crime followed in the monsters' wake. People turned out to be even crueler than the monsters.

The situation was saved by a mysterious hero called Zero, mankind's first real superhero. Single-handedly, he took on monsters and criminals alike. Over time he gathered disciples who shared his glory, and countless other heroes followed in his footsteps. Under his leadership the monster population was reduced and crime was brought under control. Then, after five years of war, the great hero vanished without a trace. No one knows that Zero's mysterious hood concealed an ordinary young man who is now simply looking for a job because his sister has kicked him out of the house. Will the hero decide to return? Is there still any need for glorious deeds?
