Ajin: Demi-Human Complete manga omnibus volume 2 collects volumes 4-6 and features story and art by Gamon Sakurai.

Glib high schooler Kei has discovered to his horror that death is just a repeatable event for him—and that humanity has no mercy for a demi-human. When more of their kind come out of the woodworks…their morals vary, to say the least.
