Mark turned to his Stats and Skill points that he hadn't used yet and looked through the amount of Stat points that he would need to get his True Sight skill to level up. Mark didn't have enough points to raise the skill to the next level, and he frowned as he realized he wouldn't be able to find out more about Megumi's power until he killed more anima. Mark decided not to let it bother him. Mark didn't feel like he would have a problem fighting Megumi even if he had no idea what her real power was. This wasn't the first time Mark would have to figure out an enemy's power in the middle of a battle, and it also wouldn't be the last.
When Mark starts exchanging blows with her, he knows that he will be able to find out what her power is in time.
