Buffy the Vampire Slayer and Harry Potter Crossover Fanfiction

Disclaimer: I do not own the show or the characters of Buffy the Vampire Slayer, nor do I own the characters of Harry Potter. They belong to the fantastic Joss Whedon and J.K Rowling. I'm just borrowing them…

Author's note: This is my very first Fanfiction, so bear with me if you see any mistakes or anything of that sort. This idea just popped into my head randomly.

Takes place: Buffy season 6, Harry Potter post book 7 (A year after The Deathly Hallows).

Rupert Giles took a sip of his coffee. What a change he thought. He knew he was back in America because one: the previous day, he'd been hit in the head by a demon, and he can only get that type of luxury welcome from Sunnydale. Two: he was drinking coffee that Buffy made him, instead of his usual tea. And three: Buffy. His slayer that made him coffee this morning, the same one that sacrificed herself for her sister, the same one whose tombstone lay on top of her empty grave- that she clawed her way out of- was alive.

He knew he was back in America because she was alive. Now that was what he called the best welcome back Sunnydale could ever offer.

The sound of the phone rang throughout the house, interrupting Giles's thoughts. He stood up from the couch he was sitting on, looked at Dawn- who was too engrossed in the fourth Harry Potter book- to notice him getting up or to take the responsibility of answering, and made his way to the phone. No one else was at home, though. Anya, Xander, Willow and Tara, were at the Magic Box. And Buffy went out for a walk, Giles assumed, since Buffy hadn't really announced where she was going when she suddenly walked out, after making Giles's coffee. He shook his head and picked up the phone.

"Hello?"

"Is this Rupert Giles?" asked the person on the other line. Giles could tell this person had a British accent, like his.

"Yes, it is. And who is this?"

The person on the other line laughed. "Oh, silly me. My name is Ludovic Bagman, but you may call me Ludo Bagman, if you'd prefer."

Giles raised his eyebrows and almost burst out laughing, this man on the other line just called himself the name of a character from a book. The book series Dawn was reading. Harry Potter and The Goblet of Fire to be exact. Ludovic Bagman is the Head of the Division of Magical Games and Sports. But such a thing like that doesn't exist, not in the real world anyways. Giles held his laugh, and cleared his throat.

"Excuse me?"

Ludo laughed.

"Ah, of course. A Muggle like yourself must find my name quite unusual and fictional, but you, Rupert Giles, aren't just any Muggle. Am I right?"

Giles shook his head, very confused.

"I'm sorry? What do you mean?" Giles still couldn't understand why this man was using the vocabulary of a character in Harry Potter. This man certainly cannot be a wizard from the Harry Potter world. Such a thing like that does not exist. But then, you could say the same thing about vampires, werewolves and witches and slayers. Magic still exists. So maybe this man wasn't lying.

"What I mean, Mr. Giles, is that you have experience with magic, am I right? You know it exits, you know monsters and dragons exist, and so you know that the Wizarding world exits. You, your slayer, her group of friends, and the Council."

Giles shook his head once more. He couldn't believe it. This was impossible.

"And because you and everyone else has knowledge about this kind of stuff," Bagman continued, "With the agreement of the Ministry of Magic, we have invited you to attend the 426th Quidditch World Cup!"

Giles almost dropped the phone in shock.

So it was real.

Oh dear lord, how would he explain this to everyone else? How would he explain to them that they had just been invited to attend a very special event held in a fictional world, that apparently exists, and were asked by the Ludovic Bagman? How would he explain to them that Harry Potter does exist?

He heard Ludo clear his throat.

"Mr. Giles? Are you still there? Hello?"

Giles opened his mouth to try and speak, but no sound was coming out. He heard Ludo tapping on the phone.

"Did he hang up on me? How do you work this? Muggles always make these funny phone devices look so easy to use!"

To make Ludo's life a little easier, Giles cleared his throat.

"Y-yes I'm still here, Ludovic." Giles said.

Ludovic smiled.

"Good, very good. Now, Mr. Giles, we have already booked you and your friends a tent to stay in, and we've got tickets, so don't worry about that. But please keep in mind, not to tell anyone! We never invite Muggles, like you, up to these events, unless we plan on using a memory charm on them. So be careful. And for transportation, Mr. Giles, you don't need to worry because we have arranged a Portkey for you."

Portkey? They actually get to have a Portkey? Giles grinned a little. He couldn't help it. This was all too exciting and mind-blowing.

"Um, where will this Portkey be, exactly?" Giles asked.

He heard Ludo clap his hands in excitement.

"We have placed your Portkey in the ruins of the high school, which I'm sure you remember?" Ludo asked.

Ah, of course. Sunnydale high. The Mayor. Graduation. How could Giles forget?

Giles nodded.

"Yes, I remember. When do we leave?"

"Well, Mr. Giles, I'm not coming with you, so it's just you. You leave, with your friends and Slayer, tomorrow. That gives you lots of time to get ready and a good night's sleep. 6 o'clock in the morning sharp!"

Nodding, Giles said a quick thank you and goodbye to Ludo, hung up the phone and returned to the couch, facing Dawn, who was still reading her book.

He looked at the clock. It read: 4:43 pm. That gave Giles lots of time to think everything over and get ready. He looked back at Dawn, who was staring right at him, with a look of curiosity on her face.

"What was that about?" she asked him, closing her book.

Giles took off his glasses, gave them a quick rub and put them back on. HE cleared his throat.

"Let's go to the Magic Box, and I can explain."

He stood up at the same time Dawn did. She crossed her arms and raised a brow.

"Are you leaving again?"

Giles shook his head, and placed an arm over Dawn's shoulders.

"No, I'm not. You'll find out once we enter the Magic Box."

Dawn sighed. She walked out the door, Giles following behind her. When they arrived at the Magic Box, Giles suggested calling Buffy first, he wanted to have everyone there before he gave the exciting and mind-blowing news.

Once Buffy arrived, with Spike, whom she said just happened to be there while she was patrolling, Giles gathered everyone around. He saw the look on everyone's faces, they all seemed worried, concerned. They thought he was going to announce his departure again. He clapped his hands together and cleared his throat.

"Um, I have some mind-boggling news for all of you."
