blame!

Blame!, pronounced "blam", is a seinen manga cyberpunk/science fiction/gothic Horror series by artist Nihei Tsutomu, originally published in Kodansha's Afternoon.

The story follows Killy, a silent loner wandering 'The City', an endless, ever-growing maze of random walls, stairs, and doorways, in search for Net Terminal Genes. These genes, thought to be extinct, would allow humans to access the Netsphere, the control system for The City and hopefully putting an end to the unceasing growth.
