Black Fox?

After a few moments, an armor-clad woman wearing a crimson mask enter the hall where Finn was waiting, who could it be beside Flame Captain, Grey.

Although she was covered in the flame guard armor, one could still easily see her fine curves and slim waistline and white hands, with her beautiful intelligent eyes one could only wonder just what kind of beauty was hiding behind that armor and mask. 

But Ace wasn't in the least bit interested in finding out and merely greeted her in 

Finn's impassive voice, "Good Morning, Miss Grey. I didn't disturb your rest, did I?"

"Sir… umm." Grey's clear eyes flicker with an odd glint as she continued, "Don't need to call me 'Miss Grey' just Flame Captain is fine. I… I also didn't know your name…" There was a hint of awkwardness in her voice when she asked about Finn's name.
