August 15, 1945:

The United Nations of America and Japan win World War II. Following the atomic bombs dropped in Berlin in 1945, the United Nations of America and Japan win the Second World War and East Asia is united into `the Great East Asian Union` under the name of "The Japanese Empire". Japan is prospering as the second strongest economic nation in the world after the U.S., but anti-governmental terrorist attacks are prevalent all across countries that have been absorbed into the empire.

2009:

The Japanese Empire consists of Tokyo, Osaka, and Seoul, the third largest city of Japan. Members of the Hureisenjin, the biggest Korean underground antigovernment organization, infiltrate the artifacts exhibition hall hosted by Inoue who is an influential figure in politics. The two JBI (Japanese Bureau of Investigation) agents assigned to deal with the terrorist situation are special agents Sakamoto Masayuki and close friend Saigo Shojiro. The Hureisenjin are defeated, but Sakamoto questions their motivesfor attacking a nonpolitical venue and the surprising fact that there were no civilian casualties at all.

As Sakamoto investigates the case, he finds that all the terrorist attacks carried out by the Hureisenjin are connected to the Inoue Foundation and asks for a detailed investigation into the case, but the executives of the JBI try to dismiss the case as simply another terrorist attack. Sakamoto works on the case by himself and finds out that the motives for the attacks are related to the fact that Korea is still controlled by Japan, but he is set up by the JBI executives and wrongfully arrested for the murder of a fellow police officer.

Caught up in a conspiracy, Sakamoto barely manages to escape with the help of his friend Saigo, but is badly wounded and his only friend leaves him the message that they “will meet as enemies next time.”

After his only friend turns his back on him, he begins his own quest to find the truth.
