While Shirohana was heading back to the Hall of Greater Divinity with bad news and a few shady plans, Aurus had just teleported back to the Tower of Seclusion, wanting to check the progress of Fenrir and Charisa in their skill grinding.
Whoosh!
Surprisingly, at the very moment Aurus appeared in front of the two, the two were not actually grinding their skills at all. Instead, they were waiting for Aurus to come back from where he left.
Of course, this disparity from what he expected slightly shocked Aurus, but he was able to understand as to why the two stopped grinding their skills up. He then looked at the two of them and asked, "Why aren't you two grinding your skills? Are you both done already?"
