Prompt #1: Thank You(AU)


A/N: Hi, everyone! This is my first story, so I hope you will be kind! I know that I mention that Riza is a Physics Professor in the description and not in the story. Well, I mention it offhandedly, but there is a reference. I also have future plans to continue this timeline, so there's a reason for the wacky family tree. I promise if you stay tuned for future chapters all will be revealed! I think that covers everything! Please enjoy!


In a world where there is no alchemy and none of the characters are part of the Military, Roy and Riza are not faced with an occupational barrier barring their relationship. Roy Mustang, Head Detective of Squad 12, meets Riza Hawkeye, the Physics Professor at Eastern University for the first time when he is 33 years old and she is 31 years old. This is the story of how their love began.


"It doesn't seem to be letting up, Sir. What do we do?" Detective Jean Havoc, the most senior member of Roy Mustang's squad, asked.

Roy stood by the large glass window of his office. His arms were crossed and the sleeves of his white button up were rolled up to his elbows. "What do you suppose should happen, Havoc? These murders have only began in September and twelve people have fallen victim to this killer. This killer is averaging four kills a month, that's roughly one victim per week. The public is in a panic."

"Stay and work. Got it, Boss. I'll tell the boys," Havoc sighed.

"If we don't have a lead to go off of by the time this blizzard is over, we'll all be out of a job." Roy warned. "I'll be down in the Forensics Department and see if Fuery has anything yet."

Roy and Jean walked out of the spacious office only to find Breda speaking to a tall blonde woman. She was beautiful, classically so. She wore minimal makeup and her long blonde hair was pulled back into a French Twist. She was slim, but not skinny, and she stood with an endearing confidant aura that radiated throughout the room.

"I understand that Edward Elric works here?" the woman began. She readjusted the books she held in her hand. "He asked me to fetch these books for him."

Roy and Jean watched the interaction from beside the fern that Falman had brought. He claimed that the office needed something alive in order to not seem so dead and dull. Roy had full intentions to admire the women's beauty from afar before heading off to the lab, but alas, Havoc did not. The younger male cleared his throat and marched right over to the conversing pair.

"Allow me to introduce myself," Havoc said to the woman. "My name is-"

"Don't even think about it, Havoc. You're engaged," Roy shouted from over by the fern. He reluctantly moved closer to the group. Under normal circumstances, Roy Mustang would certainly be trying to land a date with the beautiful woman, but he had a serial killer to find. He turned towards the woman and looked into her striking amber eyes. "Edward Elric, you say?"

At the woman's nod, Roy began thinking of where Edward could be. He hadn't seen the blonde loudmouth all day, but then again he was holed up in his office studying the case. "Breda, track the kid down. I haven't seen him all day. Havoc, once you know, bring him here."

"Yes, Sir!" the two men replied in unison.

The woman seemed at ease despite the situation and Roy continued to study her. Her posture was stick straight. Her eyes stayed forward. Roy could tell she was trained. Perhaps she was a soldier? He shook himself from his thoughts and directed his attention back to the real world.

"I'm going to need your name and have you state your relationship before I allow you visitation clearance. Sorry, this is standard security protocol. We're in some trying times right now." Roy spoke.

"Don't apologize, I understand. My name is Riza Hawkeye and I'm Edward's sister," Riza explained.

Sister? Roy racked his brain for a moment. He had swore that Edward only had a brother. Alphonse, if he remembered correctly. Before he could ask any questions, Havoc returned with the wanted man. Roy stared at Edward and Riza intently and blatantly. No matter how hard he looked, he couldn't see any resemblances. Edward had golden hair, Riza had blonde hair. Edward had golden eyes, Riza had amber eyes. They had similarities, Roy found, but none of them familial.

"Edward!" Riza smiled. Roy had to admit it, her smile made her a thousand times more beautiful. He watched as she shuffled over to Edward. Her heels clacked against the floor with every step. As soon as she reached him, Riza wrapped her arms around him in a gentle embrace.

"Thanks a bunch, Riza. I found a lead this morning, but I need these books to confirm it. I'm sorry I made you come out here." Edward said as he took the books. "I would have asked Al, but you know how sick he is."

"Don't worry about it. But seriously, Ed, I haven't seen you in a month because you constantly run around the country. Come back once in a while, Al misses you. It's getting hard on Grandfather to care for him. I wish I could help more, but I can only miss so many classes before I'm fired," Riza reprimanded.

Roy could only watch in awe as his rambunctious subordinate humbly took the scolding. If he said one word to the fiery blond, Edward's temper would flare and their daily arguments would begin. Roy couldn't help but wonder who this woman was. He found himself in a trance and quickly got out of it because he thought he just heard Edward say that he found a lead. His detective instincts kicked in and he interrupted the little family reunion.

"Elric, you have a lead?" Roy demanded.

Edward looked around the room at the sound of his boss' voice. He was startled to see Roy standing a few feet behind Riza. He swapped his relaxed face for a serious one and began to explain. "Uh, yeah. Fuery and I were in the lab all night. Fortunately, the last victim put up a fight. We found someone's blood mixed with his own blood. Strange part is that the sample came from the fatal neck wound, so we figured that the killer should be quite severely wounded. He may not risk another attempt unless he wants to get caught. This is our chance. Along with the third party blood sample, we found a substance that wasn't in the database, but it should be in these books."

Roy followed along intently, relieved that this case was going somewhere. He risked a glance at Riza and found her smiling proudly at Edward. "We have to get on this now. Edward, I want you to take Breda and Havoc and get back in the lab. Phone Falman and tell him to get here before the storm gets any worse. I'll be down in a few."

Despite Edward's rebel attitude, he and the other two men rushed down to the lab leaving Riza and Roy alone with the silence. Roy once again looked at Riza. "You should head back, too. This blizzard isn't going to end soon and I don't think you want to spend time hearing men talk about murders," Roy discreetly shot a glance at Riza's left ring finger and it somewhat pleased him to find it empty. "It was nice meeting you, Miss Hawkeye."

"Riza, just call me Riza," the blonde corrected. "I want to thank you for watching after Edward. I overheard him talking to Alphonse, and he may not show it but he really loves it here, and he loves the company he has here as well. I wish this lead pans out for you."

Roy watched, once again, as Riza, the beautiful mystery sister of Edward Elric, walked out of his office. In that moment, he damned his ambition for not allowing him to go after this woman and instead urging him to run to the lab and catch a killer. He ran a hand through his ebony hair and heaved a huge sigh. He grabbed a few papers from around the office and headed for the lab. He made it a few steps down the hall before a voice stopped him.

"Detective Mustang," Riza called out.

Roy immediately turned around, but not too quickly because Roy Mustang was not a desperate man. "Riza, I thought you had left."

"I was about to, but I found it awfully rude that I just gave you a verbal thank you. How about, after you close your case, I buy you dinner? Not only for taking care of Edward, but for saving the public."

"Only if you'll call me Roy. Detective Mustang is much too formal." Roy negotiated.

"It's a date, then, Roy." Riza gave him a small smile before actually leaving this time.

When he knew that she couldn't hear him any more, Roy began to laugh. The papers in his hand crinkled as he belted out his laughter. He got a date with the beautiful woman and he was about to put one of the biggest serial killers behind bars. Nothing could make this day better.
