Having been dead two times, Ray had good control over his soul. But whatever the girl was doing was behind the rules of what he had seen; a soul couldn't affect the physical world by itself.
Something was missing; otherwise, everyone could have used the same method. A piece that had to be special about her.
During the fight Ray kept an eye always on her soul; the only two moments she lost control of her soul to be seen was when she teleported. A white fox followed her body; it had no ripples in it, a pure soul.
"How much has she trained her soul to reach such a stage?" Training one's soul took way more time than one's magic; for that simple reason, Ray never followed the soul attacks.
With the answer clear to him, Ray wanted to stay down after the attack and utilize the new technique that he had learned, but his heart still wanted to fight her.
"If it's not as pure as hers, it should still help..."
