Fairy Tail HP Crossover

By: Sayaalv

(A/N: I don't own and what if FEM!Harry is Lucy's kidnapped little sister? What if Erza has been having dreams of her mate, who is none other than a certain black haired green eyed girl? Femslash, AU, OOCness, and some Bashings.)

"I SWEAR IF I HAVE ONE MORE GODDAMN DREAM SOMEONE IS GOING TO DIE!" Erza Scarlett screamed heading for the coffee pot while all of the members of the Fairy Tail guild dived out of her way as she stormed past them. She had been having dreams of someone that she didn't know and could hardly see for the last few weeks and therefor was in a murdering mood every morning until she got her coffee and/or cake in which case someone would ask about the dream and she would blush until her face matched her hair.

"So what kind of dream did you have about your mate this time?" Natsu asked grinning as Erza began to chug some scolding hot coffee, causing her to spew it out in his face in a classic spit-take as her face burned bright red. It was a common fact among the guild members that being so powerful and having most of her magic sealed caused Erza to have a mate, and that was who she had been dreaming about recently.

"Ah. Another one of those dreams then." Gray teased causing Erza to blush brighter and glare at him.

"At least I got a better look at my mate this time. I could actually see what she looked like." Erza said sighing as she grinned goofily at the remembrance of what her mate looked like while not noticing everyones jaws dropping.

"HER?!"

"YOU'RE MATE'S A GIRL!?"

"IS SHE HOT?!" Were just some of the more obvious shouts among the guild members, the last one causing Erza to shoot straight up with her sword out and glaring around dangerously. The guild members gulped since she wasn't even this angry when someone had knocked over her cake.

"WHO ASKED THAT!?" Erza roared furiously and very overprotective, no one was allowed to even think about her mate like that except for her. Everyone pointed at each other so that no one person was truly set up to take the fall which caused Erza to glare even harder with a threat of impending doom surrounding her.

"No one's allowed to think of my mate like that but me. GOT IT?!" Erza said her voice a soft deadly whisper at first before screaming the last two words, causing everyone to nod their heads rapidly.

"So what does your mate look like Erza? If you draw a picture of her then everyone can keep an eye out for her which might make her be found quicker." Lucy said hoping to distract the scarlet haired woman from thinking of different ways to kill anyone who so much as looked at her mate funny. Erzas mood immediately changed from battle hardened S-rank Re-Equip Mage to twenty year old woman who was love sick.

"Levi give me some colored pencils and a piece of paper so that I can draw a picture of my beautiful mate." Erza said causing the book-worm to immediately hand her the requested items and watch as Erza began to sketch and color furiously.

"Here. This is a picture of my mate. Put some pants on Gray!" Erza said holding the picture out to Natsu, Gray, who had subconsciously stripped again, and Lucy who immediately crowded around the picture. Gray and Natsu whistled at the picture of the black haired green eyed beauty who looked to be a teenager while Lucy was staring at the picture in shock and growing horror, along with slight anger.

"She's one heck of a looker." Gray said slipping on some pants so as to avoid Erzas wrath.

"For once I agree fully with Gray. You're really lucky to have such a looker for your mate, despite the small age difference." Natsu said being insightful for once and recognizing that the girl on the paper couldn't be any older than thirteen or fourteen, which made her about six or seven years younger than Erza.

"Open the Gate of the Water Bearer! Aquarius!" Lucy chanted holding out her Celestial Key and aiming it right at Erza with a look of protective rage on her face. Everyones head snapped up as the Water Spirit emerged from the nearby mini-pool and looked around annoyed before scowling at Lucy.

"What did you summon me for…and who pissed you off?" Aquarius asked raising an eyebrow at the rage on Lucys face as the blond Mage glared at a confused looking Erza.

"She's Arianna's mate!" Lucy snarled pointing at Erza who was looking between Lucy, the picture, and Aquarius confused and curiously. Aquarius adopted a stony face as she stared at Lucy and Erza with cold eyes.

"Arianna, my little Arianna, is her mate?" Aquarius asked her voice cold and hard as she stared at Lucy and Erza, causing many to wonder what was going on.

"Yes and I'd thought you'd like a chance to warn Erza about what she can and cannot do around my little sister and your honorary daughter." Lucy said cracking her knuckles with a dangerous look on her face as she stared at Erza murderously, Aquarius not far behind.

"Thank you and for once I won't wash you away with her." Aquarius said growling low in her throat as she glared at Erza who was merely looking between the two of them utterly confused.

"Wait. Hold on I'm lost. Why do you want to warn Erza about what she can and can't do around your little sister and Aquarius's honorary daughter? And who's this Arianna person?" Natsu asked scratching the back of his head confused.

"Arianna is my younger sister who is only thirteen and is the girl that Erza has apparently been dreaming about. Aquarius took a liking to Arianna before she was kidnapped at the age of six and adopted her according to Celestial Spirit laws." Lucy answered while still glaring and scowling at Erza somewhat dangerously while Aquarius nodded her agreement to this.

"Wait so my mate is your sister and her daughter?" Erza asked looking at Lucy and Aquarius wide eyed and paling rapidly, there weren't many things that scared the Re-equip mage but an overprotective Celestial spirit mother, especially one as powerful as Aquarius, and Celestial mage big sister were definitely a scary thought.

"I'm screwed." Erza said with a ghostly pale face, causing everyone to nod their agreement to her short statement. In a castle in England on Earth a black haired green eyed teenager woke up from a strange dream.
