After God. Volume 8: 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.
Tokinaga`s condition continues to worsen by the day, and there`s nothing doctors can do for him. But when Tokinaga realizes Obikawa can create the medicine he needs, will Obikawa`s new drug finally cure him? Or will Tokinaga find himself slipping down the same path as Volov?
