To be honest, ever since she met Aria, her skills had always been put to the test. Before, she was always confident in her own power and never doubted the fact that she was a prodigy. In fact, she really was one.
It was just that Aria challenged her intelligence and skills to the heavens. Beyond what was known to mankind.
From when they fought the disgusting Cluster together, she was pushed to use her power to extreme limits, to points that she didn't even know were possible.
However, she had to admit that she quite liked this kind of dynamic. She was humbled down, but it was great.
The technique Aria relayed on to her. It started from a simple chat when they were both free. From there, Aria had told her to work on that technique for it would be useful in the future.
Did she doubt her words? Totally.
Did she go along with her words? Yes, yes, and yes.
