Thirty years after the gods reduced Tokyo to rubble, survivors set out to answer a seemingly impossible question--how do you kill a god? Japan has been invaded by gods--and they've left nothing but death and destruction in their wake. With entire cities now classified as uninhabitable danger zones, Anti-God researcher Sachiyuki Tokinaga is determined to find a way to take down the gods and save humanity. When chance leads him to high schooler Waka Kamikura, the two may just end up changing the fate of the world forever. Tokinaga has successfully negotiated a treaty between humanity and the snake god, but the danger isn't over yet. Waka's been taken by a god named Volov, who claims to be a former friend of the snake god. Could Waka's friend Shion have something to do with why the two gods turned against each other?
