Naoki Urasawa's 20th Century Boys, Volume 3 (Naoki Urasawa's 20th Century Boys #22-32)

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.

It turns out that the Friend's plan to destroy the world was dreamed up long ago by a group of boys playing "good guys against bad guys"... And now, the only one who can stop this diabolical plot from succeeding is the one who came up with it - Kenji!

Kenji races home and picks up the newspaper: sure enough, the mystery microbe has hit London. He thinks back over everything that has happened and what he and his childhood friends dug up, and is forced to face the unbelievable truth - someone really is putting into motion the story Kenji made up as a child, and people are dying because of it!
