Gilgamesh
Volume 6: In the Soul Eclipse

While the children of Orga deal with a devastating loss, the ice-cold Countess attempts to make a kill of her own, pushing Tatsuya to shut her out at last, in a violent, spectacular rage. Isamu, in turn, gets even closer to the secretive widow and demands to know how this sick war began - and what part he and the Countess truly play.

Thus, the truth of Heaven's Gate is revealed.

Elsewhere, a key Heaven's Gate Player is murdered by the least likely soldier in this shadowy combat. And as Gilgamesh regroups and restores their power, Kazmatsuri strengthens his own force, at last showing to what depths he has descended in effort to end the conflict.
