Mark knew that Luna's powers would be restricted in the battle, but he didn't think it would be this extreme. The game told him that the masters needed to rely on their servants during the battle, and that meant the master wouldn't be allowed to have powers to fight with. The game must've restricted Luna's powers in order to make sure that she was a proper master candidate.
"What is going on? I know I have my mana, I can feel it. So why can't I bring it out? What is a master? Why are they telling me that you're my servant? This makes no sense. I never signed up for something like this. Why was I chosen for this?"
Luna suddenly turned to Mark with a lot of questions, and Mark leaned back as he told Luna to calm down. He didn't have anything to do with her being chosen. It was a random draw that just sucked her in without his consent.
"I wouldn't have chosen you if I had a choice in the matter. I didn't have a say either."
