The trio, Dagan, Azazel and Ramiel fell to the ground and grunted in pain and humiliation, at finding out that it was a bad idea thinking that they could hold off Adrik from killing everyone in hell because of his rage.
At this point neither of them, could do something so simple as holding off their brothers who were having problems controlling himself at his first transition. It's really going to be bad that their father comes back to see that everyone is dead except for his children.
"We can't continue this way." Azazel breathed tiredky, while Ramiel was left speechless because he wasn't one who liked involving himself in anything stressful." At this rate, we wouldn't be able to stop him if he entered the human world."
