After God, Vol. 4 by 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 swore to slay the gods, which makes learning of the god living inside her all the more disturbing. Meanwhile, the snake god who kidnapped Yoriko and took the form of her fiancé, Minami, has begun drawing the attention of the other gods. With all eyes now on him and the institute, what fresh horrors will the gods’ newfound scrutiny spell for the human researchers?
