Naoki Urasawa's 20th Century Boys, Vol. 6

This is the story of a group of boys who try to save the world! As boys, Kenji and his friends came up with a bunch of stories about an evil organization bent on world destruction. As adults, someone is now turning their fantasies into reality!

Humanity, having faced extinction at the end of the 20th century, would not have entered the new millennium if it weren't for them. In 1969, during their youth, they created a symbol. In 1997, as the coming disaster slowly starts to unfold, that symbol returns. This is the story of a group of boys who try to save the world.

Fourteen years after Bloody New Year's Eve brought the world to the brink of extinction, Neo Tokyo in the year 2014 has fully recovered and become a thriving, multiethnic metropolis. Kanna has survived the chaos and is now 17 years old--and has just stumbled upon a terrible truth that may change her destiny.

Meanwhile, at a maximum security prison ten kilometers out in the middle of Tokyo Bay, a young manga artist learns firsthand the chilling downsides of the world he now inhabits. Things go from bad to almost unbearable when he's thrown into solitary confinement right near one of the prison's most notorious inmates. Has all hope been lost, or will this mysterious prisoner offer the frightened artist his only true shot at escape?
