Hey all! This is my first ever Fairy Tail / Harry Potter crossover! To be more precise, it's a crossover of Harry Potter and the AU Fairy Tail I created in 'The S-Class Mage'. I hope you enjoy it!

NOTE: Despite Lucy's major role in the first few chapters, Wendy and Meledy are the major Fairy Tail characters in this story.

Disclaimer: I do not own Harry Potter or Fairy Tail.


A serene figure watched a group of mages attack a large black dragon. Giving them a sad smile, she clasped her hands together as if in prayer and focused.

Magic power began to swirl around her as the guild mages joined hands in a circle and Acnologia sent its' breath attack down on them. Right before it connected, she flung her arms out and everything went white.

Acnologia took one last look at the place where the island once stood and gave a victorious roar, before flying away.

"Shit!" Mavis Vermilion swore uncharacteristically. "The Fairy Sphere didn't work right!"

"But then..." She frowned and scanned the area in confusion. "If they're not here... then where are they?"


Dumbledore shot up from his desk in surprise when a large group of people fell out of thin air to his office floor.

"What the hell?" One of them, a teenage blond girl, jumped up and looked around in disbelief. "We're alive?"

"Woohoo!" A rose-haired boy cheered. "We survived!"

"Perhaps you could explain." Dumbledore suggested, drawing their attention to himself. "Who are you and how did you find your way here?"

"Well..." The blond one, who Dumbledore supposed was their leader, scratched her cheek hesitantly.


"I see." Dumbledore finally sat down and folded his fingers together. "The combined energy of the dragon's attack and the protective magic of that island you spoke of must have created a rip in the wall between dimensions. Truly an unprecedented phenomenon." He glanced at Happy, Charle, and Pantherlily. "Those... Exceed, I believe you called them... they are creatures unheard of in this world. That certainly lends some credence to your tale."

"Yeah..." Lucy sighed. "I guess we'll be leaving now. We have to find a way to send us back."

"Why not use the library we have here?" Dumbledore suggested. "This is a school of magic, after all. There might be something useful in there."

Makarov eyed him doubtfully."I sense a catch here. What are you up to?"

"Too true, Mr Makarov." Albus chuckled. "However, I do not request much. In exchange for allowing you to stay in the castle and use the library, I would like some of you to teach a class on alternate magic. In addition, Miss Heartfilia..." He turned to Lucy. "I realize I'm putting a lot of trust in you after we only just met, but it has been my intention to separate the positions of Deputy Head and Head of Gryffindor House."

"The Head of what?" Lucy frowned in confusion.

"One of the four houses of Hogwarts." Dumbledore clarified. "In any case, I would like to ask you to be the new head of Gryffindor House. I think Minerva, the previous Head, is beginning to crack under the workload and I believe that as Guild Master, you can manage being in a position of leadership."

"I see." Lucy bowed to the Headmaster, who bowed back, recognizing the custom as similar to one of the Japanese. "I'll try not to disappoint you."

"Now then..." Albus glanced at Wendy and Meledy. "I would also propose that young Miss Marvell and Miss... um I'm sorry. I didn't catch your last name."

Meledy hesitated.

"She's Meledy Scarlet." Lucy told Dumbledore. Meledy glanced at her in shock and elation.

"I see." Dumbledore nodded. "I propose that Miss Marvell and Miss Scarlet join the first-years as new students of Hogwarts when the term starts in one month. I am willing to lend you enough money to acquire school supplies and wands before the year starts and you can pay me back."

"Of course." Lucy nodded. "Much appreciated... Headmaster."

"That aside..." Dumbledore's eyes began to twinkle. "I do have something you could help me with. I originally planned to ask my groundskeeper, but you seem more organized. Don't worry, it's an easy job. You can make some of your necessary purchases while you're at it."

"Very well." Lucy agreed. "What's the job?"


One minute to go, and I'll be eleven. A scrawny glasses-wearing boy called Harry Potter observed dully. Thirty... twenty...ten... nine... maybe I'll wake Dudley up. That'll annoy him... three... two... one...

The door of the sea-enclosed shack rattled loudly as someone from outside kicked it.

"Oi!" An angry female voice shouted. "Open up in there!"

A second loud crashing noise woke up the large boy known as Dudley. "Where's the cannon?" The disoriented boy mumbled, looking around slowly.

A crash echoed behind them and Harry's uncle Vernon ran into the room, holding a long rifle and pointing it at the door fearfully.

"Who's there?" He bellowed. "I'm warning you! I'm armed!"

There was a short pause, then the door frame lit up with an eerie violet glow and the door disintegrated into nothing before the stunned family's eyes. The shocked group watched as a robe-clad teenage blond girl walked in. Casting an annoyed glance at the howling sea outside, the intruder waved a short gleaming object at it and a mermaid-like woman appeared in the water, calming it down instantly before disappearing again.

"I don't suppose you could make me some coffee, could you?" The girl asked Vernon, seemingly unconcerned with his gun. "It's been a pain getting here." She strode over to the sofa and Dudley scooted away, terrified.

"Right..." The girl blinked, reaching into her robes and taking out a sealed letter, scanning it before looking around the room. "So which one of you is Harry Potter?"

"M-me..." Harry stammered from his makeshift bed on the floor.

"Huh." The girl raised an eyebrow. "That fits with what Dumbledore said."

Vernon gave a weird rasp. "I demand you leave at once!" He commanded. "You are breaking and entering!"

The blond sent him a bored look. "Shut up." She grunted, waving an arm and causing a column of violet light to disintegrate most of his rifle. Harry's eyes widened as he understood what happened to the door.

"Anyway..." She turned to Harry. "I was told it's your birthday, so happy birthday, I guess. I don't have a gift for you but if you insist, I'll get you one later today."

"Um..." Harry looked puzzled and slightly afraid. "Who are you?"

"Right, manners." The girl slapped her forehead. "I'm Lucy Heartfilia. Alternate Magic teacher and newly appointed Head of Gryffindor House of Hogwarts." She held out a hand and Harry shook it tentatively.

"Well?" She barked, slumping back on the sofa and glaring at the Dursleys. "Where's that coffee I asked for?"

Sighing as she noticed them incapable of moving, she muttered something that sounded like 'never mind' and set her legs up on a low table.

"Um..." Harry started. "I still don't really know who you are, Miss Heartfilia."

"Lucy will do." The blond waved a dismissive hand. "At least until the school starts, then apparently you're to call me Professor. And I told you, I'm a teacher at Hogwarts." She narrowed her eyes. "You don't know what Hogwarts is, do you?"

"Not really..." Harry mumbled. "Sorry."

Lucy ran a hand through her hair in exasperation. "This is why I love Fiore, no hiding magic from civilians there."

She sighed and leaned forward. "Listen up, Potter... Harry. Since your family decided to keep you in the dark, it falls to me to explain. Hogwarts is a school of magic, the same one where your parents learned it." She frowned. "I'm so glad Dumbledore explained your family history. I still feel out of my depth here."

She turned to Vernon and glared at him angrily. "I was told you received a letter that was meant to be given to Harry later on. This is my first time doing this, you fat idiot, and you're making it definitely more difficult than I think it should be!"

She turned back to Harry and sighed again, noticing that she seemed to do so a lot. "Anyway, Harry, you're what's commonly known as a wizard. I was told your parents were fairly skilled, and that you have a high chance of being powerful as well." She reached into her robe. "Anyway, here you go. Your Hogwarts acceptance letter."

Harry took the letter from her eagerly and opened it, scanning it carefully. Eventually he looked up. "What does it mean, they await my owl?"

Lucy started. "Right." She muttered, before giving off a shrill whistle. A large owl swopped into the room and held out its leg.

"Owl post..." Lucy shook her head in amusement, writing a brief note and tying it to the outstretched leg. The owl hooted and took off, flying out again.

"Ok, I sent confirmation that you got your letter." She told Harry. "Now, any other questions?"

"He's not going." Vernon cut in, regaining some nerve.

"I'm told people like you who can't use magic are called Muggles." Lucy gave a dismissive scoff. "I hardly think that decision falls to you."

"We swore when we took him in that we'd put a stop to that dangerous nonsense." Vernon growled. "That we'd stamp it out of him! Wizard, indeed!"

"You knew?" Harry gasped. "You knew I'm a wizard?"

"Of course we knew!" Petunia screeched, causing Lucy to flinch at the volume. "How could you not be, my damn sister being what she was? She got a letter just like that and disappeared off to... to that place, and came home every summer turning teacups into rats! I was the only who saw her for what she was – a freak! But my parents, no, it was Lily this and Lily that, they were proud of having a witch in the family!"

She took a deep breath and launched into her tirade again.

"Then she met that Potter at school and they left and got married and had you, and I knew you'd be just as weird, as abnormal as they were, and then they went and got themselves blown up and we got stuck with you!"

"You told me they died in a car crash!" Harry protested.

"No, nothing of the sort." Lucy gave yet another resigned sigh. "I was briefed on your history earlier, so I can explain most of it. It starts with this wizard who went dark, like mass murdered dark and everything. He called himself Voldemort." She snorted. "Stupid name if you ask me. Anyway, he was taking over this country and those who stood in his way were all killed. One of the only safe places was Hogwarts. Supposedly Dumbledore was the only person Volde-idiot was afraid of. Anyway, your parents – strong magic users from what I've heard – were pretty close to Dumbledore, so he never tried to recruit them. I guess he wanted them out of his way, though, because he showed up at their place ten years ago and had them killed." She eyed him with a mixture of sadness and nonchalance. "I didn't know them at all, so sorry if I sound uncaring about that. What's really confusing, however, is that he tried to kill you as well, but the curse shot back at him for some reason. The only thing you have as proof of that encounter is that scar." She pointed to the lightning-bolt scar on his forehead. "After that, the current groundskeeper of Hogwarts retrieved you from the ruins of the house and took you to those biased morons you call family."

"Load of old tosh." Vernon snarled. "Now listen here, boy. I'll admit there is something weird about you, probably nothing a good beating couldn't have cured... and as for your parents, they were weirdos, no denying it, and the world's better off without them if you ask me. Always knew they'd come to a sticky end-"

Lucy pushed herself up from the sofa, her finger glowing violet. "Watch it." She warned curtly.

Harry chose to ignore the exchange. "So what happened to Voldemort?"

"Good question." Lucy shrugged. "I have no idea. Dumbledore maintains he's still out there, but powerless to do anything. Something about that night must have really messed him up."

Harry frowned as doubt began to creep in. "Lucy, um... I don't think I can be a wizard."

"I'm told children often show instances of accidental magic." She observed, confused. "Hasn't anything unusual ever happened around you?"

Harry pondered that for a moment, recalling various moments from his childhood and the recent trip to the zoo, and looked at Lucy with a smile. She gave a sigh of relief and smiled back. "You see? I have a feeling you'll fit in great at Hogwarts."

"He's not going." Vernon regained his power of speech. "He's going to go to Stonewall High and be grateful for it. I've read those letters and they say he needs all sorts of rubbish... spell books and wands and-"

Lucy cut him off. "I really doubt you have any say in the matter. He's going to go to Hogwarts as his parents wished, spend time with other young wizards and witches and study under Albus Dumbledore, an experienced Headmaster-"

"I am not paying for some crackpot old fool to teach him magic tricks!" Vernon roared defiantly.

"See, now I'm annoyed." Lucy scowled. "I've known the man for less than a day and he's already done more for me and my friends than most others I know, and that includes my birth father. You'll understand if I don't let your insult go unpunished." Her finger lit up again. "The 28th Seal, Pinpoint Laser version." She intoned, causing a thin beam of violet light to shoot from her fingertip and slice through the wooden ceiling, allowing several loose planks to fall down on Dudley in a heap.

"Come on, Harry." Lucy snapped, sending one last glare at the Dursleys as they struggled to pull Dudley out of the wreckage. "Let's go."


AN: Sorry if that was kinda rushed. I cut out Lucy's explanation to Dumbledore because everyone who reads this should know what happened on Tenrou Island. Also, McGonagall is still the Transfiguration teacher. She's just not the head of Gryffindor house anymore.

Next chapter will be out in about a week.

Thanks for reading!
