The summer sun hung high over Central City, turning the stone streets into shimmering ribbons of heat. Bee buzzed lazily from the flower bushes lining the Führer’s estate, and not a single cloud dared interrupt the relentless blue sky overhead.
You, however, were in absolute heaven.
Born and raised beneath the scorching Ishvalan sun, this weather felt almost comforting. Warmth soaked pleasantly into your honey-brown complexion as you sat barefoot in the backyard, your long skirt spread beneath you while you helped your four-year-old son construct what he proudly declared was “the biggest sand fortress in Amestris.”
A tiny toy soldier was ceremoniously placed atop the highest tower.
“There,” he announced proudly, patting another wall into place. “Now nobody can get him.”
You smiled, brushing a strand of your hair behind your ear. “He’s very well protected.”
“I know.”
He nodded with all the confidence only a four-year-old could possess before immediately abandoning the fortress in favor of chasing a butterfly.
The back door slid open.
Roy emerged carrying a stack of government reports tucked beneath one arm.
He looked…less like the Führer of Amestris and more like a man who had personally offended the sun.
His black dress shirt was rolled to his elbows, the collar unbuttoned, and despite every attempt at maintaining his usual composed appearance, a bead of sweat traced slowly down his temple.
He made it exactly three steps onto the porch before stopping. “…It’s hotter than the gates of hell.”
You looked over your shoulder. "It isn’t that bad...."
Roy stared. “It is forty degrees Celsius.”
“So?”
“So?”
He gestured wildly toward the sky.b“The air is trying to kill me.”
Before you could answer, your son came barreling back toward the porch carrying an armful of smooth rocks.
“Daddy!”
Roy smiled immediately despite his suffering as he placed the reports down. "Hello, Lieutenant."
“I made rocks.”
“…You mean you found rocks.”
“I made them now.”
Roy accepted that explanation without question as his lips twitched. “Understandable.”
The little boy tilted his head, studying his father’s face with all the seriousness of a military inspection.
“Daddy…”
“Yes?”
“You’re all sweaty.”
Roy sighed. “Unfortunately.”
The child looked toward you then back to his father then back at you again.
“Mama isn’t sweaty.”
You raised an eyebrow.
Roy pinched the bridge of his nose. “Your mother grew up somewhere considerably hotter.”
The little boy gasped as though he’d uncovered the greatest mystery in Amestrian history. “So Mama doesn’t get hot?”
“I get hot,” you corrected gently. “I just don’t mind it very much.”
He accepted this explanation for approximately three seconds.
Then his tiny face lit up.
“My mama is stronger than the sun!”
Roy barked out a laugh despite himself. “I don’t think that’s exactly—”
The little boy had already sprinted toward the front gate.
“MISTER HAVOC!”
Jean Havoc had just arrived to grab a report he needed, cigarette hanging lazily from the corner of his mouth.
“What is it, buddy?”
“My mama is stronger than the sun!”
Jean blinked. “…She probably is.”
“And Daddy is weak!!.”
Jean looked at Roy.
Roy slowly closed his eyes. “Don’t.”
Jean grinned. “Oh, I absolutely will.”
By the following morning, the rumor had somehow escaped the estate.
Not because of Jean.
Jean had actually tried.
Unfortunately, your son possessed the unstoppable social confidence of a tiny politician.
Everyone received the news.
The guards.
The maids.
The kitchen staff.
Several secretaries.
General Armstrong.
Major Hughes....( Thanks Maes and his big mouth )
Even Grumman.
By lunchtime, half of Headquarters knew.
By dinner…
Edward Elric found out.
He happened to be visiting Central alongside Alphonse when your son spotted him across Headquarters.
“UNCLE ED!”
Edward turned just in time to catch forty pounds of excited child launching directly into his stomach.
“Oof!”
Your son wrapped both arms around him. “My daddy’s weak.”
Edward blinked. “…I’m sorry?”
“He melts in summer.”
Edward slowly looked past the child.
Roy happened to be walking down the corridor with Riza.
The second Edward saw the faint sheen of sweat on Roy’s forehead…A dangerous grin spread across his face.
“Oh…”
Alphonse immediately recognized that smile as his shoulders slumped. “Oh no…”
Edward crouched to your son’s height. “So…the Führer’s weak in the heat?”
The little boy nodded enthusiastically. “And rain.”
Edward’s golden eyes widened with theatrical delight.
“Mhm! Mama says Daddy doesn’t like rain.”
You had never said that.
Not exactly, you had once mentioned that rain made Roy’s flame alchemy useless.
Apparently your son had simplified the information.
Edward stood.
His shoulders shook.
Then, despite every attempt to resist…
He burst into laughter.
“Oh, this is priceless.”
Roy immediately frowned.b“…Elric.”
Edward wiped tears from his eyes. “Sorry...I’m sorry—”
“No, you aren’t.”
“I’m really not.”
Edward straightened before loudly addressing the entire hallway.
“Attention everyone!”
Roy closed his eyes. “…Don’t.”
Edward ignored him completely. “I have an important military announcement!”
Several officers looked up from their paperwork.
General Armstrong paused mid-conversation.
Even Breda leaned out of an office doorway.
Edward proudly pointed toward Roy.
“The great Führer of Amestris has two natural predators!”
Roy sighed the exhausted sigh of a man who already knew where this was going.
Edward dramatically raised one finger.“Summer.”He raised another. "And rain."
The hallway erupted.
Laughter echoed off polished marble.
Havoc nearly dropped his cigarette.
Breda had to lean against the wall.
Fuery laughed so hard his glasses slid down his nose.
Even Falman smiled into his clipboard.
Armstrong, ever dignified, placed one enormous hand over his mouth in a valiant but unsuccessful effort to suppress a chuckle as Maes barked out a laugh, his glasses nearly falling off.
Only Riza remained perfectly composed.
Almost.
There was the faintest twitch at the corner of her mouth.
Roy looked toward his wife. “You could help.”
You offered him your sweetest smile. “I could.”
“…”
“I’m choosing not to.” You replied.
Your son beamed up at you. “Mama’s stronger than the sun.”
You leaned down and kissed the top of his head. “I don’t know about that.”
“Mama stronger than daddy.”
Riza snorted as she turned her body away all while the little boy blinked.
Edward folded his arms triumphantly. "Well, that’s official then."
Roy gave him a flat look. “You do realize I outrank you.”
Edward shrugged without the slightest concern, that same cocky grin still on his face. “Doesn’t change the fact that the Führer gets defeated by weather.”
“I am not defeated by weather.”
“Tell that to the puddle forming on your forehead.”
Another round of laughter swept through the hallway.
Roy looked heavenward as though asking whatever higher power might be listening why this, of all things, had become his legacy.
He had survived war.
He had survived homunculis
He had overthrown a dictatorship.
He had rebuilt an entire nation.
Yet somehow, thanks to one observant four-year-old and one incorrigible Fullmetal Alchemist, he would forever be remembered as the Führer who lost every summer to his sunshine-loving Ishvalan wife.
