Ajin: Demi-Human Complete manga omnibus volume 4 collects volumes 10-12 and features story and art by Gamon Sakurai.

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.
