Aria rested for a while, then resumed her training using Atha's form. And so on until night falls and the sun begins to set.
When Aria has mastered several sword techniques, a mock battle between two Athas is held. A fake Atha versus the real one.
Aria thought she would lose badly, considering Atha had been a knight for thousands of years. In addition, the knight's experience was much more profound than her, considering she had only once fought life and death.
Who would have thought her attack and defense power was on par with Atha? She was able to apply the same pressure as Atha as well as withstand the knight's most potent attack.
In the end, Aria lost the battle because she wasn't used to this extreme exertion. But the result was satisfactory, and in Regine and Atha's eyes, Aria could survive in the beast world, but Aria doubted it.
