After the spread of the "Apocalypse Virus" in Japan in the year 2029, the country has been placed in an emergency state. Since the spread of the virus, the Japanese government lost all of its foundations, and the reign of the international organization known as GHQ began ruling the country. Now Japan is in a state of martial law, which is enforced by the GHQ, and is considered a "quasi-independent" nation.
10 years pass, and we see the story through the eyes of Shu Ouma, an average 17-year-old teenager who lives a normal life. However, his normal life style is soon shattered after his chance encounter with Inori Yuzuriha, who eventually involves him with the anti-government group she is a part of, known as Funeral Parlor, or Undertaker.
