From the Publisher:
Reads R to L (Japanese Style), for audiences rated teen plus.
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.
The time has come. The Friend reveals all about his conspiracy and declares that he shall destroy the world within seven days. Kanna plans a music festival to evacuate people to the Expo venue, which is the only place the dictator holds sacred and the only place safe from destruction. While the 20th Century Boys race toward the final battle, Kenji is coming back to Tokyo!!
