Abara

Denji Kudo looks ordinary until he transforms into a Gauna, a creature of white bone that grows armor and blades out of its own skeleton. He hunts and is hunted by other Gauna across a vast, decaying megastructure, while soldiers try to contain the outbreak. The plot is thin on purpose. Nihei, who made Blame, cares about scale and surface: enormous architecture, black-on-white bone, bodies that flower into weapons. Across only two volumes it moves fast and explains little, trusting the drawing to carry the dread. If you want a clean story, look elsewhere. If you want a building-sized nightmare rendered in ink, this is concentrated Nihei.
