As the supreme protector was already quite injured, Alessia continued attacking him without holding anything back. As soon as she could eliminate one of the S rankers from the opposite side, the better it would be for her side. Obviously the other S ranker who had just appeared was unwilling for that to happen, so he tried to intervene between the battle of Alessia and the Supreme Protector.
But before he could do that, Mercus got in his way. With his Rage Overflow state still activated, Mercus charged toward this new opponent. This man was holding a special looking curved blade in his hand so Mercus was sure that he was a warrior. So he was hoping to have a blood pumping close quarters bout.
