Gangsta., Vol. 4 (Viz Media)

As Hunters infiltrate the walled city of Ergastulum, more and more Twilights fall victim to the violence and chaos that result. The Cristiano Family, traditionally (and secretly) charged with overseeing the Twilight population, is keeping a close eye on events - and they don't like what they see. The young Cristiano boss hires the Handymen to escort Twilights to a safe place for protection, but a new, even more dangerous threat is on their doorstep.
