Hell Is Dark with No Flowers, Vol. 2 (Manga)

A sin greater than the sum of its parts…A request to exterminate a nue brings Shiroshi Saijou and his assistant, Seiji Tohno, to a manor in a remote village. The family that lives there claims to be cursed, though Shiroshi and his rival, Odoro, are certain there’s something far more sinister hidden in their bloodstained past. When tragedy strikes in the dead of night, Shiroshi and Odoro begin their race to expose the sinner and get to the bottom of what happened two years ago. But they must tread carefully, for one misstep means the punishment of Hell would fall upon themselves…
