Zuru, a scavenger from the starving Electro-Fisher settlement deep in the City's lower levels, triggers a Safeguard attack while searching for food. The wanderer Killy arrives armed with his Gravitational Beam Emitter, hunting for a human carrying the Net Terminal Gene that could halt the City's endless, hostile expansion. This manga adapts the 2017 Blame! film, retelling how Killy and the scientist Cibo help the Electro-Fishers escape the collapsing lower levels.
