A vast city lies under the shadow of colossal, ancient tombs, the identity of their builders lost to time. In the streets of the city something is preying on the inhabitants, something that moves faster than the human eye can see and leaves unimaginable horror in its wake.

Tsutomu Nihei's dazzling, harrowing dystopian thriller is presented here in a single-volume hardcover edition featuring full-color pages and foldout illustrations. This volume also includes the early short story "Digimortal."
