The previous two fights, in other words those of Nerissa and Camila happened before Vivian's fight even started, then we had Vivian dealing with the enemy's leader which was now being casually taken to where Mina was.
But if you make memory, you'll remember that the white-haired poison princess said something along the lines of "sister Mina is waiting for the last one of their group to be taken to where she is", before letting the girls of the sect take the leader away.
So, we still won't return to actual present, which is just when Vivian finished her fight, in fact we'll go even further back in time than we did for Nerissa and Camila's fights, to when the leader had given his initial orders, namely for the vice-leader and the treasurer to lead the others out of the camp, but given that you just saw those guys trying to retrieve the things from the secret storages, things didn't go as they should have, and we'll see why right now.
