Tamara Volkova

A Russian who specializes in wide-area suppression, she has a magical lighter that can turn into a flamethrower, thus her "Phoenix" moniker. She is at odds with Mia for being too laid back, calling her "Texas girl". She serves as a magical girl because of her sister, later revealed to be an illusion the Russian general staff at the Zavolzhsky weapons testing site use with a fantasy-granting device to brainwash Tamara with the intent to use her until she dies in battle.
