After Roa disappeared, did the "Counter Force" leave any effects on Ciel's body?

Nasu: The moment Roa disappeared, Ciel lost her immortality. Ah, but the self preservation magic she had learned is still there, and thanks to that she was fine. As usual, she's built for playing rough.
Takeuchi: How much magic potential does Ciel have?
Nasu: Far above that of an A rank mage. In terms of Ciel's excellent qualities, the ceiling of her power to preserve magic energy is extremely high.
