Lucifer strodded back to hell in rage, he was destroying everything and everyone in his path. He has never felt this much angry his entire life, but he did good to avoid going to his room because at this point, he's sure that he's going to kill Marilyn if he goes up there.
Unfortunately, the unranked weak demons were the ones at his disposal, and the humans in the torture were sacrificial lambs for him to take out his aggression on.
His throne room was a mess, and one would not be able to see any single item still back in shape if they had entered here.
After he was done with the damage, he sat down on the floor while breathing hard, the walls of his palace were shaking with the intensity his anger carried, and he tried to remind himself that he shouldn't let a mere peasant like Ethan, to bring him down to his lowest point.
