Three days ago.
After settling into Rank 11, Michael had not been idle. The first thing he did was return to Aurora and pay close attention to the situation there.
Unlike the previous opening of the Origin Battlefield, Awakeners were no longer forced to remain inside until the entire period ended. This time, they could leave and return as they pleased. The only restriction was that they had to spend a required amount of time within the Battlefield before the monthly reset. This made things much more convenient for many Awakeners.
Michael knew his sudden rise in the rankings would cause reactions. It was impossible for someone in Rank 11, especially someone like him, to not attract attention. So he returned to Aurora to make sure he wasn't blind to whatever followed.
Fortunately, the Supernatural Association agents had once again proven useful. Thanks to them allowing him to borrow their source of information, Michael was able to learn a few things.
