The demons were apprehended in mere seconds after the arrival of Harrison's father, Elron Rain. When faced against a Titled Knight, there was no opportunity for a Golden Knight to do anything but face his fate as the difference between a Titled Knight and Golden Knight was far too large, not to mention that Elron Rain was not an average Titled Knight, but one of the strongest in the empire.
With his monstrous strength, he quickly got out of the facility with the five demons being dragged behind him with chains. The chains were normal chains that even a Bronze Knight could break, but they were reinforced with Elron's mana, making it impossible for even the Golden Core demon to destroy them.
Upon seeing the five demons, both Harrison and his uncle, Rudgar Rain, opened their eyes wide as even though they were ready for it, seeing the demons was a different story.
