After God. Volume 6: Sumi Eno

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.
Waka finally makes a break for it after being kidnapped by the god Volov, but just as her freedom is within reach, Alura stops her dead in her tracks. Meanwhile, Volov begs his former best friend Obikawa for help, though after struggling with his vice for so long, he may already be beyond saving.
