She couldn't allow that to happen! She couldn't afford to lose this battle no matter what, otherwise she would have no other way out.
After suffering defeat on Roy's hands for all this time, she felt that now was the only moment that she could actually have a chance at defeating him.
She had been able to break through to the Rank 4 early Warrior Rank just a few days ago, and she had yet to fully establish her current strength.
But after seeing with her eyes and feeling with her body during their fights the monstrous growth of Roy day by day, she didn't dare to take him lightly.
She didn't understand why he was so weak, having only a Rank 2 Warrior strength at this age with the potential and talent he was showing, but that wouldn't last for long.
Even now, she could feel during his movements that he had actually broken through the Rank 3 Warrior stage quite some time ago, stabilized his Rank, and was running towards the next Rank.
