The Celestial Apostles are dead...so are the Sin Demons.
Ashton's grand scheme played out well, everything fell within his expectations and Humanity went home with another victory under their name.
The Qliphoth and Laguna were still there. Ashton made a conscious decision to not destroy either for now since they still have a purpose. However, its citizens no longer had freedom.
Before he left the Qliphoth with his men, Ashton pulled every single demon and angel into a dream.
A dream that he fabricated to make them believe that everything was just fine. He erased their memories of the battle. He fabricated a memory for them which made them believe that the Apostles and the Sin Demons entered solitary seclusion to prepare for their attack against Humanity.
He even delegated tasks for them to follow in the absence of their leaders, which will mostly come from him.
