20th Century Boys: Chapter Three - Our Flag 2009

It is the Third year of Friend, or 2017 on the old calendar. The world is governed by Friend, now the World President. The virus-plagued Tokyo is now isolated from the rest of the world with towering walls and oppressive surveillance. Friend gives another prophecy, "At noon on August 20th, mankind will be terminated by aliens. Only those who believe me shall survive." In the meantime the Secret Base friends are fugitives who are active underground. Yoshitsune leads a resistance group called Genji Faction. Kanna left Yoshitsune to form a more militant group in preparation for an armed revolt. Kanna is determined to go ahead with her radical activities despite the concerns of her surrogate mother, Yukiji. Maruo now works incognito as manager to national superstar singer Namio Haru. First he finds Kiriko and then Keroyon, a classmate who's been missing since the class reunion. Otcho sneaks into Tokyo and finds Kanna. Kanna's reckless plan to hunt down Friend with an army of armed Tokyo residents, would leave nobody alive. In an attempt to stop Kanna, Otcho gets a radio station to play Kenji's new song. On the outside of the wall dividing Tokyo from the world, a man tries to break down the maximum security border patrol station. He has a guitar with him. He calls himself Joe Yabuki. And he mumbles, "I'm going to see Kanna" Is Kenji alive? What is Friend's last scheme for August 20? What is Friend's true identity?
