Truth.

Valerian watched as the two people were separated after they exchanged their blows. The young man observed the two of them, neither did Titan move nor did Morgana. He sighed and shook his head as he said, "You both will never reach a result." 

Morgana did not turn her head to look at him, because she knew that he was speaking the truth. If she could not take down the berserker in front of him with that last sword attack of hers, she will not be able to do anything. However, Titan did not know that. 

The berserker said, "If you are holding back with me then you are making a mistake. I can still go on." 

Morgana replied, "Indeed, I should just use a few skills that I have left and kill you. But that will be staining the tradition. I am not like you, uncultured, however, I want to ask you, do you really wish to risk it? Do you not know the way things are back in Valkyria? They will never accept a loser as their emperor."
