SailorStar9: So, I was watching Full Metal Alchemist when this idea came to my mind. (Sighs) Guys and girls, is it too hard for you to leave a review, instead of just putting this fic up on your favorited list and story alerts?

Basic Summary: The sequences of transmutation: Comprehension, deconstruction and reconstruction. But what if there was a power that could not only nullify the abilities of Alchemists, it is also the polar opposite of the Philosopher's Stone?

Disclaimers: I own nothing, except for the plot bunny and my OC.

Prologue: Beginnings

Three years prior…

"Auntie!" the now armored Alphonse Elric cried out, kneeling before the Rockbell Automail after their failed human transmutation. "Please… please help my brother…"

"Al, is that you?" Winry gaped, recognizing the voice. "You two came back from your training?" she asked, Edward having been bandaged up and lay on the bed. "So what happened?"

"You tried to recreate Auntie Trisha, didn't you?" Ranko hissed, her filtration seals were already attached onto Ed's bandaged stumps to prevent infection.

"I see." Roy Mustang opened the door. "That was the light of a human transmutation. I've never seen such a strong transmutation response before. Excuse me." He shut the door and presented his silver pocket watch.

"A State Alchemist?" Winry echoed.

"And what does a soldier want?" Pinako was on alert. "As you can see, these two are critically injured."

"I received this letter." Roy pulled out the envelope.

"That's the one the brother wrote to all of Dad's acquaintances." Al gaped.

"We have also been searching for your father, Hohenheim." Roy explained.

"Hohenheim-sama is still missing." Ranko supplied. "We have an injured person here. Please leave."

"If he is still alive, even after attempting a human transmutation, then I have more interest in him than his father." Roy admitted. "He might be able to become an excellent State Alchemist."

"He has done nothing." Pinako defended. "Go home, Ranko needs to concentrate."

"It's all right, baa-chan." Ranko assured, standing up from her seat by the bed. "I'll see our guest out."

Roy's eyes widened when he saw the familiar uncolored pacifier around the young woman's neck and snorted. "I thought your name sounded familiar. Didn't expect you find you here. I am the State Alchemist, Lieutenant Colonel Roy Mustang." he introduced himself. "Visit Central City. So…" he turned to his childhood neighbor after shutting the door. "Want to fill me in, 'Little Crybaby'?" he smirked, only to dodge the hail of senbon needles she tossed at him.

"Complete with wire, nice…" Roy whistled, once Ranko calmed down and withdrawn her weapons.

"I still have my senbon pouch, you know." Ranko warned.

"Touché." The Flame Alchemist joked. "I see you've improved on your seals."

"And you guys thought those things were worthless." Ranko retorted.

"Guess we were wrong." Roy nodded. "Now, how did you end up here? Weren't you supposed to be working as a maidservant somewhere?"

"Long story short: Uncle was duped, that guy was a slave trader." Ranko growled. "If Hohenheim-sama hadn't bought me back then, I'll be in a whorehouse before I was twelve. I swore a life oath to him ever since. You're still going to take them." she concluded.

"The decision is up to them." Roy shrugged.

"Knowing those two rag-rats," Ranko rolled her eyes. "Or least Ed, he'll go through it. As for Al," she snorted. "He's bound to follow his brother wherever he goes."

"You seem sure." Roy remarked.

"Hey, I was the one who diapered those two." Ranko smirked. "I know how they think. Hey, Roy," she remarked. "Can I ask for a favor?"

"What is it?" Roy asked.

"Take care of those brats for me." Ranko requested. "I can't protect them forever, not where they are going."

"I'll try, but no promises." Roy replied.

"Thank you." Ranko whispered with a relieved smile. That's right. She mused. Once the pacifier activates, the Wheel of Fate will turn and everything, including my life, will… "Roy?" she blinked, the Flame Alchemist's shadow suddenly towered over her. "Stop this." She sighed, pushing him off.

"Are you serious, Ranko?" Roy pressed.

"You should already know," Ranko gave him a sad smile. "The two of us, we belong to two different worlds."

SailorStar9: Now that's done, read and review.
