Blame! Volume 4

Maybe on Earth… Maybe in the distant future… Sibo, having entered a secondary level between the basal reality and the Network Sphere, helps Killy defeat the Keepers by damaging the node they use. Killy and Sibo finally find themselves inside the "Toa" corporation. But both the local security artificial intelligence and the silicon life forms residing here are extremely unfriendly towards the guests.
An architect by profession, Tsutomu Nihei was able to create an astonishing world where technological images of the distant future blend with the bleak spirit of post-apocalypse. The manga "Blame!" is one of the universally recognized masterpieces of science fiction, renowned for both its unique artistic style and its unparalleled atmosphere of despair and mystery.
