It was information that was meant to be revealed later, but Damien dropped it suddenly to snap August out of his strange state.
It was too random, after all. Plus, what reason did Damien have to take the Dragon Emperor as a subordinate?
As August stared at him with the same bewildered expression, Damien grinned.
"It's just for safety. He's not actually listening to my orders or anything. But, he can request my help if he needs it and he will properly dedicate himself to training you and your friends. It's good to have insurance, right?"
August nodded dumbly. He would've done the same if he was in Damien's position. This information didn't necessarily concern him. It was just an insane thing to hear.
Damien flicked him on the forehead, continuing as if it was no big deal.
