A/N: Hey Guys, I have deleted the other chapters as I'm rewriting it again. Hope that you like this version as much as the previous story.

Previously

Hawkeye sighed in defeat; she should have figured it out earlier…This long-term mission as Mustang has brilliantly put it, was rather obvious that it enables him to have more time with Edward alone without the interference of the bothersome officers in Central. To put it bluntly, this mission is a typical 'a trip for two' on a honeymoon to Hogwarts.

"I'll let this one pass, as long as you give me your word that you will show up for your work here at least 3 days a week to ensure that your paperwork is done on time."

"Deal."

"And Edward, this condition applies to you as well."

"Wha—" A bullet was fired just inches to his left. "Sure! No problem!" The blonde alchemist corrected immediately.

"Good." Hawkeye smiled in satisfaction. "When exactly is the escort arriving?"

Ed scanned through the letter for a date, "On the 1st of August."

"Then before that…" Hawkeye reloaded her gun switching the safety key off with an audible 'click', smiling rather sweetly that typically screamed 'If you don't finish your paperwork, prepare to face my wrath'. "You better finish off your paperwork, Fuhrer Mustang."

End Flashback

Chapter 2

Ed nestled himself comfortably in Roy's arm, sighing in contentment. 2 years ago he would have never imagined himself in this position with 'Colonel Bastard', Edward chuckled inwardly as he reached out to the Flame Alchemist pressing a kiss to his lips. Angling his head allowing better access for his lover to deepened their kiss.

"Breakfast?"

"Mmmhmm…" Roy hummed in response as he tightened his arm around Ed's waist, enjoying the presence of his young lover within his arms. He nuzzled his nose in the crook of Ed's neck, breathing in his lovely scent.

While Ed would really love to remain in Roy's arm, his stomach however begs to differ. "Roy, I'm hungry~~" He let out a weak whine.

"Alright…alright…" The man chuckled adoringly at his love. "Let's freshen up. Then, I'll whip up something for the both of us. How does that sound? " Leaning his forehead against Edward's, gazing straight into that expressive eyes he adore.

Ed nodded allowing Roy to lead him towards the bathroom. All of a sudden, the young blonde stopped abruptly before whirling around shooting a warning glare at Mustang. "But, we're not doing any of that in there this time…"

Roy smirked at the tint of redness creeping up the blonde's cheek. "You're not exactly being very convincing with that blush on your face." He purred, taking advantage of the situation as he sneaked his hands underneath Ed's top.

"Ahh…" Edward let out a moan as Roy nibbled on his earlobe, licking sensually down his neck leaving kiss mark along the way.

"No…no…stop!" Blushing heavily, Ed managed to regain his control, slapping Roy's hand from roaming any further. "Bastard, I'm serious here! After those six continuous sessions last night, my back is killing me!"

"I'm just kidding, Ed. We'll just freshen up, I'll even give you a back rub in the process…after all, I am party responsible for that."

"You better be…"

Mustang chuckled adoringly at the sight of his lover stomping towards their bathroom after that last statement before moving to follow as well.

Just right after finishing their breakfast/lunch, the doorbell rang.

"I'll get it." Mustang stood up to get the door. Behind the door revealed a woman with a strict appearance in clothing that look somewhat like a robe, her hair tied up tightly into a bun at the back of her head.

"Good evening, I'm Professor Minerva McGonagall, Deputy Headmistress of Hogwarts." She gave a slight nod as she introduced herself.

"Roy Mustang, a pleasure to meet you. You must be the escort indicated in the letter then?" Roy inquired receiving a confirming nod in return.

"It's a pleasure meeting you as well, Mr. Mustang. I assume that Mr. Edward Elric is here as well?"

"He's in the kitchen cleaning up, why don't you step in and have a seat?" Mustang stood aside allowing the professor in.

"Roy, who is it?" Ed questioned as he step into the living room tying his hair into his usual braid.

"Professor Minerva McGonagall, our escort to Hogwarts."

Ed greeted Minerva with a faint smile. "It's a pleasure meeting you, ma'am." Somehow, in a weird sense she actually reminded Ed of his Alchemy Teacher, Izumi. "I'm Edward Elric."

Minerva lifted a small smile in return. "Likewise, Mr. Elric."

Taking a look at the time. "We have not much time to spare; we'll be leaving in exactly 30 seconds." Minerva said as she held out a rock in her palm. Roy and Edward look at Minerva with mix confusion.

"Simply touch the rock and it will transport us to our destination. I'll explain in detail later." Though skeptical of what Minerva just said, they did as they were told after sensing the urgency in the professor's tone.

Within seconds, all of them felt a pull and vanished.

Outskirts of Hogwarts, somewhere in the Forbidden forest

Three figures reappeared out of nowhere in the woods. Among the three, Minerva is the only one that seemed rather unaffected by the after-effect of port-key traveling. While our flame and fullmetal alchemist are leaning against each other for support, trying to get use to the dizziness and nausea currently experiencing. Edward in particular is trying hard to keep his breakfast in as all the dizziness made his stomach churned.

"You ok, Fullmetal?" After getting rid of the dizziness in his head, Mustang glanced at the blonde in concern.

"'m fine…Just dizzy…" Ed rubbed his forehead barely registering their current location.

"Where exactly are we?"

"We are currently in the Forbidden forest." Minerva replied eyeing both alchemists in concern. "Are you two feeling alright? I'm terribly sorry that I failed to inform you of the likely side-effect of port-key traveling."

Ed flashed her with a weak smile and a wave of hand indicating that he's alright. "How far exactly is here from where we were before?"

"I'll say an estimate of a thousand miles or so?"

"What!?"

The transfiguration professor couldn't help but chuckled at Edward's expression of mixed confusion and amazement while Mustang on the other hand caught himself and managed to remain composed.

"But…ahh…how…what…" In the process of trying to comprehend how the hell they have moved from one place to another with distance of more than a thousand miles within seconds, Edward has totally lost it.

"Ed, calm down." Chuckling as he wrapped an arm around his young lover. "You're sprouting nonsense."

"You'll understand everything in much detail later after your meeting with the headmaster." Minerva explained. "Right now, the headmaster awaits your presence." Minerva said motioning them to follow her.

Hogwarts

"Lemon drops." Minerva whispered to the stone gargoyle as it sprang apart revealing a moving spiral stairs behind.

"Roy, I am not hallucinating right?" Edward whispered as he stepped onto the moving spiral stairs.

"I'm trying to convince myself I'm not." Roy trying to make sense of everything he saw as he came in. "Did you notice the candles floating in mid-air?"

"You mean the one we saw along with the moving staircase and talking portraits? Yup, would really want to deny that but yea I've noticed." Ed started waving his hands around in hysterics. "This is just like another one of those fairy tales that Elysia love to read."

Minerva shook her head in amusement after hearing the conversation of the two alchemists as he lift up her hand, swiftly knock on the door.

"Come in." A rich voice sounded behind the door.

Minerva push the door open to let Edward and Roy through first before going in herself.

"Headmaster." Minerva nodded with respect towards the man with half-moon spectacles behind the table. "Edward Elric and Roy Mustang from Amestris." Minerva introduced.

"Ahh…I've been expecting both of you." The headmaster crossed his fingers together with a friendly smile as he motioned them to the chairs. "Have a seat."

"Welcome to Hogwarts, School of Witchcraft and Wizardry. I am Albus Dumbledore, headmaster of Hogwarts." The headmaster of Hogwarts introduced himself rather joyfully. "I do hope that your journey here was pleasant."

"It's very unique. Very different from what I had expected." The flame alchemist replied with a strained smile.

"To put it bluntly, we did not really expect ourselves to get pull into some kind of whirlpool thingy, only to find ourselves thousand miles away from Amestris and with some hell of dizziness and nausea." Edward started listing of his fingers.

Albus blue eyes twinkle merrily behind his half-moon glasses as he chuckled lightly at Edward's straight forwardness.

"Fullmetal, mind your manners." Mustang reminded his lover though inwardly he wholeheartedly agrees with what Edward just said. "I apologize for my subordinate's behavior."

"No, it's alright. I have to agree with Mr. Elric on this one. Traveling using the port key while it is useful however does have its downside. Once, I found myself soaking wet as it transported me in the middle of the lake." Albus said chuckling to himself at the memory. "Now, moving onto our agenda for today…I understand that both of you have questions that you need answers to."

"You have to realize that we were rather skeptical at the point of time when we received your letters, especially when the letters were being delivered by owls." The flame alchemist pointed out. "However, you did manage to get our attention with the arrays that you have presented us with in your second letter. The arrays coincide with the arrays that we are currently investigating, hence, causing it to fall under our jurisdiction."

Fuhrer Mustang elegantly crossed his gloved fingers with a calculating glint in his ebony eyes. "We will offer you our assistance in going undercover and protect that boy that you mentioned in the letter. In exchange, you will provide us with all necessary information and access we require to carry out our investigation as well as your word and co-operation to not interfere unless asked to."

Professor McGonagall has to admit that the flame alchemist's presence naturally commanded attention and respect; he has the air of confidence and charisma essential in a leader that compels people to follow his decision without a doubt. A natural leader.

"I don't see any problem with that." Albus nodded in the terms that Roy has just laid out. "Anything else?"

"Oh…and due to our other commitment to our country, Fullmetal and I would need to be available in Central Headquarters at least three days a week." Mustang added wincing inwardly as he remembered Hawkeye's threat.

Minerva frowned at that, 3 days a week? While it would be rather easy for Mustang who will be going undercover as a professor to be absent 3 days every week, however it would be a rather different matter for young Edward who will be going undercover as a student. "If you don't mind me asking, what commitments do both of you have exactly?"

Both alchemists turned around looking rather surprise at Minerva's question.

"Uhh…didn't you know who we are when you sent the letter to us?" The young blonde inquired curiously.

"I was told that both of you were the best alchemists in Amestris, especially Mr. Elric." Minerva answered, growing rather confuse by the second.

"That's all?" Edward widened his eyes in astonishment.

"Yes, was there anything else important that I was not informed of?" The transfiguration professor asked while fixing a pointed stare at Albus. "Do you know something else that I don't?"

Roy and Ed looked at each other before turning their attention back to Minerva and Albus. "I believe a proper introduction is in order. Fullmetal."

Edward sighed in resignation before performing a formal salutation. "Brigadier General Edward Elric. Military state alchemist code name: Fullmetal Alchemist at your service."

"Fuhrer Roy Mustang. Military state alchemist code name: Flame Alchemist at your service." Roy ended his introduction with a playful wink at the gaping transfiguration professor.

"Albus, did you know about this? Fuhrer and Brigadier General!?"

"I'm rather surprise myself actually. I merely knew that both of them are talented alchemists in the military, and both of them are among the others I've screened through that have better magical capacity to be selected."

"No offense intended but...Mr. Elric, aren't you a bit young to be in the military? If you don't mind me asking, how long have you been in the military?" It was rather obvious that the young blonde did not just join the military recently, given his rank and the experiences that are evident in his stance and eyes.

"Five years since the age of 12, ma'am." Edward answered. He let out a small smile when he felt Roy's comforting hand on his shoulder.

"Fullmetal is the youngest state alchemist to be qualified into the military. A young prodigy in alchemy and also known as the 'Hero of People' as the citizens labeled him with." Roy added as he gazed at Ed with pride.

Saying that both of the professors were rather shock would be an understatement after they heard those statements from both alchemists. However, both decided not to probe any further understanding that it is rather a sensitive subject especially for the young blonde. Minerva can't even begin to imagine the military experience that the young blonde has been exposed to at such the young age…and the fact that for some reason that she was rather fond of the young alchemist makes it hard for her not to feel protective of Ed.

"Anyway, I'm sure we'll be able to go around both of your schedules and sort out ways for you two to fulfill your commitment back at Amestris."

"That would be great."

"Splendid." Albus' eyes twinkled joyfully. "Now, in regards of your undercover identity…Mr. Mustang, you will be our new Alchemy Professor while Mr. Elric will be posing as a 6th year student just transferred here. Any questions so far?" Albus asked.

"Just one, I don't really know a thing about how things work here. Wouldn't it be suspicious for me to be posing as a 6th year student? I don't even have any knowledge of the teaching of the first five years." Edward pointed out.

"No worries there, our professors will help you the best they can to get you equipped with the necessary knowledge during your four weeks stay here."

"Okay, I guess…"

"Mr. Mustang, will you be able to give me your teaching plan for the students before the 1st of September?"

"Sure." Roy nodded.

"If you don't mind headmaster, we would like to know more about our mission during this school year in detail." Edward reminded.

"Yes, of course." Albus nodded.

To be continue…
