Note: My first Harry Potter/FMA crossover. I read a couple and really enjoyed them. I decided to try my hand at one.

Disclaimer: Neither FMA nor Harry Potter belong to me. So sad.

Chapter One: Enter the Elrics

Edward and Alphonse Elric crashed to the ground in the lobby of some strange castle.

"Ouch, that hurt," commented Al, rubbing his backside.

"Hey Al, where are—" Ed is cut short when he sees his brother. "Al…?"

"Yes Brother?" Al asked, not understanding where his brother was going with this.

"Look at your hands," stated Ed.

Al looked down, expecting to see his normal armored hands. Instead, he saw skin, flesh. "I'M HUMAN! I'M HUMAN! WE GOT MY BODY BACK BROTHER!" The brothers start to dance around in circles.

"May I ask how you got here?" The boys turn to look at the newest arrival, who was wearing strange clothes, a robe and a pointed hat.

"Where is here and if we knew how we got here, wouldn't we know where here is?" questioned Ed, glaring at the new arrival.

"You are at Hogwarts School of Witchcraft and Wizardry. I am the head master, Albus Dumbledore," replies Dumbledore, noting the strange color of Ed's eyes. Sensing the strong aura of power coming from the two boys, he asked, "Why don't you two try us out? How old are you two boys anyway? Have you studied anywhere before?"

"I'm 16 and Al here is 15," replied Ed. "We were home schooled for several years. We had a really good teacher." Ed, thinking about Izumi, shivers.

"I take it that you both posses names…"

"I am Edward Elric and this is my little brother Alphonse."

"Where are your parents? They will have to okay you coming here."

A look of sadness crosses the boy faces. "I guess you could call us orphans. We are all we have," pointed out Ed.

"Then you will need a place to stay until the semester starts in two weeks. Might I suggest the Leaky Cauldron? Allow me to escort you there now." Before the brothers could protest, they where being shuffled out the door.

"Here you go boys," reported Dumbledore. "You are in room 134. I will send someone with your supply lists to show you around." Before the baffled brothers could protest, Dumbledore was gone.

"Guess we will just have to play along with this Al," stated Ed. "It doesn't look like we are going to find our way back home anytime soon."

"Ed…Ed it's you," a strangely familiar voice sounds behind the brothers. "It took me a whole thirty minutes to track you down."

Ed and Al turn around to see Hikari Kokomachi, down to the green hair held back by her crystal rose. "Hikari, what are you doing here?"

"I came looking for you. I tracked the gate's frequency here. I didn't come by the gate of course. I have other methods of travel. Sorry Ed you have to meet certain conditions before you can travel those ways. Who's this?" asked Hikari motioning to Al.

"That's Al," grumbled Ed.

"Oh, you got your body back when you crossed the gate, way to go. Sorry I didn't recognize you. I was never shown a picture of you before you were in the armor. What about you limbs, Ed?" asked Hikari, her question was quickly answered by a headshake no from Ed. "So, what are you going to be doing while you are stuck here? I know you will try to find a way back. I just don't know how soon you can find a way."

"We are supposedly attending Hogwarts," grumbled Ed again. "We're just not sure what to think about it."

Hikari smiled then quickly cast a spell, forming a letter. "I'm transferring from my school so that I can attend Hogwarts with you two," replied Hikari to the brothers' curious looks. "I plan to attend Hogwarts as a sixth year exchange student. I'm going to go get a room and then I will see about getting you some funds."

Meanwhile, at the Burrow, Dumbledore apparited, "Harry, Ron, Hermione, I need to discuss something with you."

"Of course Professor," replied all three in unison.

"Since you are Gryffindor Perfects and the Gryffindor Quidditch captain, I feel that you are the best ones to take the two new transfer students under your wing." An owl start starts hovering in front of Dumbledore. Dumbledore removes the letter, reading it silently. "Make that three. You will find them in rooms 134 and 135 at the Leaky Cauldron. Here are your letters and theirs too. See you on September first," with that Dumbledore disapparited.

"Well, we'd better tell mum where we're going tomorrow," Ron mumbled.

The next day, at the Leaky Cauldron, Ed was downstairs eating breakfast, three teenagers walk in. One of them was a boy with messy black hair and round glasses. He walks up to the caretaker. "We are looking for Alphonse Elric, Edward Elric, and Hikari Kokomachi." Ed had looked up at the mention of his name. The caretaker points toward Ed.

"There's one Mr. Elric. I'm sure he knows where the other two are."

The trio walks over to Ed.

"What do you want?" asks Ed, glaring at his milk.

Hermione notices Ed's plate is clean but he hasn't touched the milk. "Aren't you going to drink your milk?"

"WHY SHOULD I DRINK THIS EVIL SUBSTANCE? IF I DON'T DRINK IT, I WON'T DIE!"

"Brother, just drink the milk," comments a new figure, dressed the same as Ed, who was wearing his normal black boots, black pants, black tank top, black jacket with white trim, and his red over coat with the seal on the back, only instead of a braid, he had a long low ponytail. "It'll help you get taller."

"Are you calling me short, Al?" twitched Ed.

"No, no, never brother," apologized Al. "I just meant it would help you grow. Just think, taller than Winry or Hikari. You might even pass Armstrong."

"Heh, heh, I kind of like that idea," commented Ed. "But I 'm still not drinking it."

"Oh! I guess we haven't introduced ourselves properly," Al says while turning to see Harry, Ron, and Hermione. "I'm Alphonse Elric, brother, introduce your self."

"Fine." Ed stands up from his stool. "I'm Edward Elric, Al's older brother. Hikari is—"

"Present," came a cheerful voice from the entrance. "Hikari Kokomachi, at your service. You three are?" She asked, motioning to the trio.

"Oh," The black-haired boy said. "I'm Harry Potter, and my friends are Ron Weasley, and Hermione Granger." Whispers could be heard in the background, "Harry Potter! The boy who lived! The Chosen One!"

"For once their not whispering about me…That's a strange feeling…" Ed said to himself.

"It feels good that they're not talking about me either brother." Al replied.

"Well, you're not in a giant suit of armor now, so they have nothing to talk about, except our fashion sense…"

"Yeah…Hey remember that time we snuck into Lab Five, and I was in 'Stealth Mode'?"

"You call that stealth? You were going ceeeeer, ceeeeer, ceeeeer, ceeeeer, all the way there!"

"Yeah, but I was being as quiet as I could!"

Harry, Ron and Hermione were looking at Ed and Al like they were crazy. "What?" Both of them asked in unison.

"Nothing."

"So, I take it you all are supposed to show us around and help us with our school supplies? Oh, Ed I talked to Mustang, and he took some money out of your R-fund to function as your money here, same for Al," Hikari assumed.

"Figures he'd want me to do some research while I'm stuck here…Wait…I'm causing him more paperwork! I wonder how many times Hawkeye has threatened to turn him into Swiss cheese?" Ed wondered.

"Brother, we don't have a clue what we need for school!"

"Oh! The headmaster gave us these," Hermione handed each of them a letter. "Oh yeah, how old are you two?" She asked the brothers.

"I'm 16 going on 17, and my brother is 15 going on 16," Ed stated.

"So what years are you in?" Hermione asked.

"I know I'm at least a sixth year," Hikari mumbled as she opened her letter. "Yup, I was right, sixth year. What are you guys?" Hikari asked the three wizards.

"We're all sixth years too, how cool is that?" Hermione replied.

"Wicked," Ron said in amazement.

Ed opened his letter. "I'm a sixth year, what about you Al?"

Al was jumping up and down yelling, "I'm a sixth year! I'm a sixth year!" He ran to Ed and squeezed him in a big bear hug.

"Al…Can't…breathe…you're…choking…me…!"

Al let his brother go. "Sorry, but I was so happy that we're in the same year."

"Hopefully you'll be in the same house." Harry said.

"House?" Both of the brothers asked.

"It's where you live while you're at Hogwarts." Ron stated.

"Come on people! Let's go shopping!" Hikari was dancing some sort of dance in front of the others. "I want to check out all of the stores, hurry up Ed."

"Fine let's go, but I'll need that money, where do we go to get it?"

"Follow us." All three of the wizards said as they walked out of the leaky cauldron. The three wizards weaved expertly through the crowd, and the others followed close behind until they reached a giant white marble building. "This is Gringotts, the wizard bank. Try to be polite to the goblins, even if their not polite to you," Hermione warned. The others took that advice and followed them in.

"I need to make a withdraw from the account of Hikari Kokomachi please. In addition, may I make a withdraw from Edward Elric's account? I believe you have the keys," Hikari said as she walked up to the first free goblin. The others were at another free goblin. "May we please go to our vaults with those people over there, they are showing us around."

The goblin nodded and smiled evilly, "Of course, just don't touch the vault doors, you just might get stuck." These words made Edward shiver.

"Come on! We're about ready to go down to our vaults!" Harry cried as Hikari, Ed, and Al ran towards them.

On the way to their vault, Al thought his brother was looking a strange tinge of green.

'Damn. I'm going to be sick. The speed of this cart is going to make me blow chunks. The stale air in my face doesn't help either…'

The car they were in slowed down to a stop, Ed let out a sigh of relief. The goblin put a key in the door, to reveal mountains of Galleons, Sickles, and Knuts. "Hikari Kokomachi, this is your vault."

"Hikari, I didn't know you had this much money in you R-fund."

"Most of this is from my family, not my R-fund. Where I'm from my family is rich," Hikari gives every one a sweet smile and scoops up a large handful of each. Then, jumped in and the cart was off.

After a few minutes, the cart slowed down again. "Edward Elric, this is your vault." The goblin smiled as he noted the green tinge to Ed's face. Ed and Al quickly jumped out of the cart. The goblin turned the key and revealed a good amount of Galleons, Sickles, and Knuts.

"Wow…" the brothers said in unison. "Hey Hikari, how did you convince Mustang to give me this much money from my R-fund?"

"Let's say I told him you were going to do some research while you are here. It's not like its stuff you wouldn't do anyway."

"Your right. Hey, I'm giving Mustang more paperwork! All right!"

"Brother, don't be so mean," Al said defensively.

"Fine," Ed scooped up some money, and so did Al. "Hey Hikari, When you see Mustang next, tell him thanks for the money." With that, the two brothers hopped in the cart, and Ed prepared for another sickening ride.

"So Ed, who is this Mustang? Is he your dad?" Harry asked over the sound of the rushing air.

"Yeah right," Ed snorted. "Like I'd let that flame happy idiot be my father." When Ed noticed the strange looks he was getting from the others, "Al and I are orphans; sometimes I think its better that way." Ed said so that the others could barely hear him.

The cart slowed to another stop, and this time the goblin said, "Weasley vault." Ron jumped out and before any of the group could see what was in his vault he was back in the cart with a small bag of money with him. The cart rushed off to its last stop. "Harry Potter." Harry jumped out of the cart to a vault with twice the amount of money of Hikari's. He quickly scooped up some coins. The cart was on its way to the surface.

"Well, I didn't bring all of my family's fortune…" Hikari mumbled to her self as they left the tunnel.

"GROUND! SOLID GROUND! HOW I LOVE YOU SO!" Ed sang as he walked to the main floor of Gringotts. Everyone turned to look at Ed.

Al said to Hermione as she looked at Ed strangely, "He was green the whole time, he doesn't like fast rides…" Hermione nodded in understanding.

"Hey guys let's hit the stores!" Hikari squealed. "Robes first!"

Madam Malkin fussed over Edward like he was a little duckling. He thought he heard "darling little first year" and when he corrected her she would mumble "no you can't be a sixth year, you're too small." Ed was trying to hold his temper down when she finally said, "Finished." Then it was Al's turn.

"So Potter, doing charity work now are we?" A boy with white-blonde hair walked into the robe shop just as Al was getting on the stool.

"For some strange reason, I can't stand you from first sight," commented Hikari. Hikari waved her hand at the boy and sent him flying out the door.

A woman with white-blond hair runs up to the boy, "Draco, Draco, are you okay?"

"I'm fine mother," replied the boy as he pushed her off him. "Let's get out of here before the Mudblood spreads her germs."

Hermione looked as if she was about cry and Harry and Ron were furious. "And I thought I was the one with a temper," mumbled Ed. The robe fittings went smoothly from that point on.

"I think the book store would be a good next stop," suggested Hikari.

"Books, books, books," sang Al. Everyone gave him a strange look.

"Um, excuse—" Ed is cut off.

"I know, I know, you need the first year books right? Well here you go." A pile of books is dumped into Ed's arms.

"Um, I also need the rest of the years' books, with an extra sixth year set," Ed asked.

"But first years don't need those!"

"I'm not a first year," Ed growled. "I'm a sixth, and so is my brother. Now give me the books." The shopkeeper just then noticed the strange color of Ed's eyes. They are golden, like a cat's, and now, his pupils were slits. The shopkeeper quickly piled up the books in Ed's arms.

"That'll be 3 Galleons, sir."

"Thank you, Come on Al, let's wait out side," When Ed went by all of the others suddenly had a sense foreboding.

Hikari stepped up to the counter, "Um I need one set of sixth year books please."

"Of course, here you go Miss. That will be Nine Sickles." Hikari handed the shopkeeper the money.

"I'll be outside with Ed and Al." Then Hikari whispered to Ed and Al, "I'll take care of the wands later."

Everyone else got their books without any mishaps.

After they were back at the Leaky Cauldron, Ed was nursing a very bad temper. In every store he was called a first year. 'I'm that short, am I?' Ed was also moping, when he heard a knock on the wall, this made his blonde barn owl, Winry, jump. Al didn't notice because he was in the floor playing with his cat, Fluffikins. "Ed, make a hole in the wall using your alchemy. I need to speak with you. Alchemy does work on this side of the gate." The voice sounded like Hikari.

Ed claps his hands and touches them to the wall. Light flashes and a hole appeared. "What do you need Hikari?"

"I came to make your wands. I just didn't want to be spotted with the needed items." Hikari places a block of ebony and a block of white oak on the floor. Hikari quickly creates a crystal rose to add to the collection on the floor. "These wands will be more powerful than the ones that they make here, because of the core ingredient." Hikari pulls out three hairs and places one on each item. "I plan to make all three at once. I am using alchemy to create them so my magic won't interfere with yours." Hikari starts making several hand signs. A bright flash of light, three wands lie on the floor. One is black ebony, one is white oak, and the third is pure crystal. Hikari picks up the crystal wand. "Ed, ebony one is yours and the white oak is your brother's. Oh, I almost forgot. Winry told me to give you this; it's to take care of your arm and leg. If all else fails, I can go get new ones from her, but I would rather not have wrenches thrown at me. You also might want to be careful about who you show your automail. I'm not sure how people will react to it here. Night." Hikari hands Ed a pouch of tools and heads back to her room. Ed fixes the wall behind her.

Note: So how do you like it? Hikari is from one of my other FMA Fanfics. She is the only character that is mine in this fanfic. I also decided that I wanted Al with Ed at Hogwarts. All the crossovers I read, and I haven't read many, always had Al back home. Sadly like everyone else I do not own Harry Potter, or FullMetal Alchemist. I wanna cry…Crack Sorry 'bout that! -' I had to knock my other half out with a baseball bat…But didn't work! Run for your lives! She's going to kill us all! Bye until next time! Sorry the chapter was so long!
