Ajin: Demi-Human Complete 4

Gamon Sakurai's hit dark fantasy series now in a new omnibus format!
"Ajin is an action-packed, supernatural thriller - and there are some scenes of some seriously bad-ass action - while underneath, it tackles issues of society, discrimination, and of course, mortality." - Kotaku
THE FINAL WAVE
Under duress, the Ministry of Welfare, which has been abusing demi-humans on behalf of the so-called business community, is ready to negotiate. Yet Samuel T. Owen, a.k.a. Sato, can’t resist giving the screw another turn—and the jolly ex-marine is more than willing, even eager, to take on the hardest of hard targets.
The breathless nightmare trip Ajin: Demi-Human, finally available in omnibus format. A thriller that just keeps on getting better and deeper.
