The Darkest Defense

Summary: In order to head off the ministry's plans to take control of Hogwarts, Dumbledore turns to an old friend in his search for a new DADA professor. Disclaimer: I don't own Harry Potter, Hellsing or any of their characters, ok?

Chapter 1: The New Professor

Seated comfortably on his throne-like chair inside his office, Albus Dumbledore sucks on a lemon drop as he pondered the latest fiasco that had plagued his school.

The death of young Cedric Diggory and the revelation that Barty Crouch Jr. had been impersonating Alastor Moody were tame issues compared to the news of Tom Riddle AKA Voldemort's resurrection. Yet despite a sworn testimony from Harry Potter as well as some rather compelling evidence he had submitted, the Ministry still refused to acknowledge the Dark Lord's return.

As a matter of fact, the Ministry had gone to great lengths to stamp out the rumors of Voldemort's rebirth and, if what his spy reported was correct, one of their steps to ensure that the truth remained hidden was the gradual takeover of his school which will most likely end in his ouster as Headmaster and the installation of a more loyal candidate.

But of course, Dumbledore was nobody's fool.

One does not get to his advanced age and NOT learn a thing or two about politics. He was well aware of Fudge's ambition and knew that his stubborn posturing was simply a way to draw the voters in. And seeing that Hogwarts once again lacked a DADA professor, the minister was sure to send his own candidate in order to have some sort of influence and presence there.

Dumbledore wasn't about to hand over that kind of control to him or to ANY of his lackeys anytime soon. Not while he had anything to say about the matter.

But where to look for a new DADA professor? There was a distinct shortage of qualified candidates and any witch or wizard that Dumbledore DID manage to hire lasted no more than a year for some strange reason.

...

Perhaps that was the source of his difficulties. He restricted himself too much in his search for a competent instructor. After all, who said that the next DADA professor had to be a witch or wizard? The thought of the shakeup that his latest scheme was going to cause made Dumbledore smile.

It was time to contact an old friend.

Hellsing Manor

Integra had to smile as she read the letter from her old friend Dumbledore.

The elderly wizard has been a family friend of the Hellsings for generations and had been the one who created the wards around the mansion as well as the restrictions that sealed Alucard's abilities. And even though its been a few decades since their last correspondence due to the nature of their respective responsibilities, the Hellsing heir still considered him as one of her closest allies.

"So the old goat seems to be in a spot of trouble, huh?" Integra mused out loud, glancing at the study materials that Dumbledore sent together with the letter. "Well I suppose I DO owe him a favor. Seras! Get in here!"

A few minutes later, Alucard's sole minion enters the office and stands in attention in front of Integra. "You called Lady Integra?" The blond haired ex policewoman asked respectfully. Even after all this time, Seras still hung on to her training as a law enforcement officer like a lifeline as though to remind herself of her identity as an individual. It was a trait which Integra admired about her.

"Yes Seras. I have a new mission for you." Integra answers, dropping a folder on top of her desk in front of the vampiress for her to read. "You are to go to Hogwarts Shool of Wizardry and Witchery and report to Headmaster Albus Dumbledore as his newest Defense Against Dark Arts instructor."

"School of what now?" Seras asks in confusion, picking up the folder and scanning the contents before looking up at her master in disbelief. "You mean they actually exist?"

"An entire society of them as a matter of fact." Integra confirms, chuckling at Seras's relative naivety. "Really now Seras. You've been fighting ghouls, vampires and variois other inhuman beings with us for more then a decade now. What's so difficult to believe about the existence of a race of magic users?"

"If they've been around all this time, why didn't they help when London was attacked by Millennium ten years ago?" Seras asks with a touch of anger in her voice. "A lot of innocent lives could have been saved."

"That's because they had their own problems at the time." Integra explained. She understood Seras's sentiments but also felt she had to explain the reason. "They couldn't afford to send assistance because they had a powerful group of supernatural terrorists to deal with just like we did so don't be too upset with them. If anything, its us who owe them because its their wards and runes which have protected our headquarters and lives."

This revelation calms down Seras but that still didn't mean that she liked her new assignment. "With all due respect Lady Integra but your safety is my primary concern. If I leave, who will protect you in place of Sir Walter and my master? Besides, I don't I'm qualified to teach ANYTHING to witches and wizards let alone this Defense Against Dark Arts." She argued.

"Seras... I'm perfectly safe here in Hellsing Manor. There hasn't been a major threat to my life since the Millennium attack." Integra assured her friend. "As for your qualifications to teach the subject, I don't believe there's anyone else in England with your credentials in battling dark creatures so Hogwarts will be getting an excellent instructor."

Seras tried to argue again but Integra cuts her off. "Enough Seras. If the foundation's army of highly trained soldiers are incapable of protecting me and the rest of England against supernatural threats, then what the hell am I paying them for? Besides, I'm not just sending you to Hogwarts to assist Dumbledore. I'm also sending you there to assess the situation."

"Assess the situation my lady?" Seras repeated curiously.

"Yes Seras. I want you to find out all you can about this Dark Lord Voldemort that Dumbledore spoke. I want to know if he is truly a threat serious enough to warrant our intervention." Integra's features then turns hard and cold. "And if that turns out to be the case, then I want you to eliminate him at the earliest opportunity. We do NOT need another megalomaniac running around thinking he is free to do as he pleases. Is that understood Seras?"

To her credit, Seras recognized an order when she heard it and responded as her training dictated. "Ma'am yes ma'am!" Seras barks out, standing at attention and snapping off a crisp salute.

Integra nods in approval and gestures towards the study materials on her desk. "Good. You have a little more than a month to go over those study materials before the next term starts. I suggest you get to it." She said. Seras sweatdrops and whimpers at the rather thick stack of folders she was asked to study but nonetheless grabs it and slips out of the office, leaving Integra by herself who lit a cigar and sat back on her chair in contemplation.

From what Dumbledore told her in his letter, this Voldemort fellow is quite a formidable force in the wizarding world. Seemingly immortal, exceptionally influential and exceedingly powerful.

But the same could be said about Seras.

As the only one turned by the original Vampire Lord himself, the ex policewoman possessed all the abilities of a pureblooded Nosferatu and none of their convetional weaknesses.

A vicious smile graced Integra's lips. Though it would be interesting to see a battle between these two monstrous beings, she had no doubt about the outcome.

None at all.

One month later...

They were going to die.

Harry was certain of it.

If only Dudley and his band of cronies didn't taunt him, they wouldn't be in this predicament in the first place. But Dudley just couldn't take a bloody hint and he lost control of his magic which in turn, attracted a number of dementors towards them.

In the end, the Dementors caught up to the fleeing Harry and Dudley and, after disabling them, was about to administer the Dementor's kiss to the cousins.

"T-This c-can't be the end, can it?" Harry mutters, futiley reaching for his wand as he watched the Dementor draw closer and closer.

But before it can do anything, sharp cracks which Harry vaguely recognized as gunshots was heard and the Dementor that was about to suck out his soul flew back screaming with a number of smoking holes on it's body. Another barrage of gunshots drives away the Dementor on top of Dudley.

Slumping down in exhaustion, Harry looks up in time to see the back of their savior. From the looks of it, it appeared to be a woman with dirty blonde hair wearing a leather coat and boots. In her hand, she held a pistol which was steadily aimed at the group of Dementors in front of her who were clustered around their injured breathen.

"Well what do you know? I guess blessed silver nitrate encased 9mm bullets also work on these things." She said before her aim shifted to one of the Dementors which she percieved to be moving. "Ah ah ah... I don't know if you can understand me but I've still got over half a clip left and I don't have a problem putting a round on what passes as those head of yours if any of you so much as twitch this way."

Apparently deciding that a tactical retreat was in order, the Dementors withdrew and after making sure they were really gone, the woman slips the pistol back into her coat and checks on Dudley first before going over to Harry. "Your magic was the one that attracted those things to you, right? You should learn to control yourself better." She stated as she scanned Harry for any injury. Now that Harry had a closer look, he can see that the woman looked just a bit older than him but still quite pretty and had startling blue eyes as well a developed, womanly figure.

"Sorry about that." Harry muttered out an apology. "But my cousin always DID know how to push my buttons so I couldn't help myself. Thank you for your assistance against the Dementors though. Are you a witch?"

"Not the sort that you're use to but yeah, you could say that I am." The woman answered before offering her hand which Harry takes gratefully as she pulls him back on his feet. "The name's Seras Victoria by the way."

"Harry Potter." Harry introduced himself which earns him a flicker of recognition from the woman.

"Harry Potter? Well thats convenient. I've heard all about you. Word is that you've been a magnet of trouble around these parts these recent years." The identified Seras Victoria remarked with a smile.

"I am? Well its kind of embarassing but you're right." Harry said with a nervous chuckle. "You're actually the second person to save me from Dementors. The first one was my old DADA teacher."

Seras's smile grew even wider at this. "Well then I guess your old instructor and I have something in common." She said.

"What do you mean?" Harry asks in confusion.

"Let me reintroduce myself then." Seras said. "My name is Seras Victoria and I'm your new DADA professor."
