In the near future, the outbreak of a terrible disease called the Apocolypse Virus places Japan under the military rule of a global organization called the GHQ - a group tasked with checking the spread of the virus and administering vaccinations. Apathetic high school student Shuu Ouma lives in Tokyo, spending his days editing videos and trying to be left alone. But things change when he meets the beautiful pop idol, Inori, who is on the run from GHQ soldiers. While trying to save her from her captors, he acquires a mysterious power called the Void Gene that allows him to pull items or weapons from anyone under the age of seventeen. Now, Shuu must decide whether to join the efforts of the well-funded radical terrorist group "Funeral Parlor" and fight against the GHQ, or shrug off his newfound power and resume his normal life - assuming that either the GHQ or Funeral Parlor's charismatic leader, Gai, will let him.
