Reinforcements (Edward Elric x Reader)

The Elric brothers are on a mission to find the philosophers stone, but on the way they meet "Scar".
After fighting "Scar" and interrupted by Colonel Mustang and his team. They are taken back to headquarters, and find out that he has been only targeting State Alchemists. Since no one can defeat him, not even Fullmetal himself, they have to call in reinforcements.

Y/n Mustang is a very special girl. She is the Quantifier Alchemist, her ability allows her to do any type of alchemy you can think of. The weird thing about it is that she can do it with out a transmutation circle, but the weirder thing is that she did not commit the ultimate taboo, Human Transmutation. She doesn't have to clap her hands or snap her fingers. She thinks of what she wants to happen and it happens. Oh, and I forgot to mention earlier, she's Mustang's daughter.
