20th Century Boys

"Mankind would not have made the new age, encountering the crisis at the end of last century, that almost wiped them out...if it weren't for "them" In 1969, "they" who were still in their youth, created a symbol. In 1997, as footsteps of the coming disaster slowly starts to show out, the symbol revives. This is a story about several boys, that save the world."
