Biomega is depressing and distressing. The most part of characters are without exspression and few talk. The edifices is very elaborated and dominate the landscape. In this view human aberration fight for change the world.
I love the style of the author Tsutomu Nihei. The design of Biomega is detailed, with gigantic structure that dominate the protagonist Zoichi Kanoe(but is same to Killy!). Is a artificial human, and search Ion Green a immortal human, for prevent the diffusion of the virus N5S as transform the human in zombi(call Drone in the manga).
Together with Knights of Sydonia this is the better manga of Tsutomu Nihei.
