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 confesses everything to the snake god Orokapi--the truth behind his crumbling body, the source of his mysterious abilities, and every other dirty secret he's tried to hide. It all started when he first met Waka, but that was in a different time, a different world--the first world. It was the moment that Tokinaga was swept into a vortex of endless tragedy. Now that the truth is out in the open, will Tokinaga finally be able to escape the cycle he's been trapped in for so long?.
