The S Rankers all took Maria away after Guang Liang finished healing Ryu's arm.
They knew that the longer they stayed, the more attention Maria would receive and that was the last thing that they wanted.
As for dealing with the people who had seen Maria…they had subordinates to take care of that.
The subordinates under them were more than enough to conquer the entire world if they worked together. So a simple task as making sure that these hunters didn't think too much about Maria was nothing for them.
After taking Maria away, they all headed to the cafe without care for the liaison from the Hunter Organization.
They just quickly tossed the destroyed dungeon core to them before letting them take care of the clean up.
Of course, that liaison from the Hunter Organization didn't dare stop them.
