A/N: Hello fellow readers and writers! My name is Ayame and I am a huge fan of Hellsing and I ADORE Alucard and Integra. I wanted to give them a scary romantic adventure and some fun and horror that stays in the Hellsing realm. As usual I always have humour in my stories and there will be some sexual content as well. However, saying that, this fic starts off light but it gets really intense and dark/gory later on. There is a little Seras and Pip in there as well cause they are a great couple, too!

I can't count the number of hours spent plotting and grinding my teeth on this lol! It has taken me a year to complete.

NOTE: I want to point out that this story takes place exactly where Hellsing Ultimate OVA episode 10 left off... exactly. It's the reason I felt compelled to write this story... the ending stole my heart. As for Alucard's newly gained power of omnipresence... I kept the abilities at the level shown by Schrodinger... no more or less. I have taken a few liberties regarding some powers though, things that I thought made sense after what has happened in the last 30 years. There are references in here from all Hellsing sources, including the manga. I have also thrown in a few references from Bram Stoker's Dracula. I wonder if you can find them? *grins*

Thanks for taking a moment to read that! I truly hope you enjoy!

**The fanart attached to this story was created by me.

Eternal Sin

Chapter 1 – Home Sweet Home

Hellsing Manor - August 2, 2030, 3:33 a.m.

"You're home— " Integra's voice was but a soft whisper as she held a bleeding finger out before her, the blood pooling into a quivering drop looking for a place to fall. "…my dear Count."

Alucard's crimson eyes gazed up at her from where he sat on the floor inside of her bedroom with his legs sprawled out before him, his back up against the wall. A hungry sigh accompanied his thirsty smile.

"Back forever more, my Countess," he murmured quietly full of fearless promises. He opened his mouth wide and stretched out his long tongue to catch the generous drop of blood.

He shuddered with delight as it splashed onto his tongue, evoking a deep groan of pleasure from within. The blood was saccharine, pure, and definitely worth the thirty-year wait. Integra Hellsing, his beautiful master, was even more charitable as she allowed him to take her hold of her, his gloved fingers curling possessively around her wrist. With a gentle but demanding tug he brought the bleeding digit closer so he could lick it thoroughly, taste every bit of that delicious warm nectar oozing from the tiny self-inflicted flesh wound.

The tall blonde gave a wry grin as she watched him feasting on her finger, his tongue cool and wet, his sultry red eyes, that were a shade lighter than usual, glowing brightly as they gazed up at her with a look she knew brought women to their knees. They shared a silent moment watching each other carefully, so carefully, that Integra did not even realize she had been holding her breath. She let him take her finger into his mouth, could feel the sharp edges of his teeth grazing lightly over the skin.

The sensation sent chills ghosting over her body.

Integra released the pent up breath as a whole whack of sensations stirred up inside, old feelings within her, feelings she had not felt for three decades. That look of deep sadness appeared on her face again and she yanked her hand free of the vampire's grip, ceasing his feral ministrations rather abruptly.

Alucard did not fight against her wishes and allowed her to pull her hand away with a low rumble of pleasure.

"That's quite enough." The leader of the Hellsing Organization chided in a brusque tone, taking a step back and crossing her arms over her chest.

The nosferatu knew that look. He understood this woman's body language and read her expressions better than anyone else did. "My absence has offended you deeply. Again…" he ventured carefully, "I am sorry, my darling master. It appears as if this joyful little reunion has opened old wounds." The corner of his mouth twitched with an ironic smirk. "I am but the salt."

That is when the youngest vampire in the room, Seras Victoria, piped up heatedly in Integra's defence. "You're not the salt, Master. It's just Master Integra has worried so much about you even though I told her you would return… thirty years is such a long time for a mere human. She's just stunned, is all."

Shadowed red eyes, partly hidden by tousled raven hair, glanced over at the female vampire with her short spiky blonde hair wearing a red Hellsing uniform, with her shadowy left arm, whose life ended at the ripe age of nineteen, thirty years ago. She was now forty-nine and looking as ever beautiful as the day Alucard turned her in that quaint town of Cheddar on a perfectly moonlit night. However, gone was the timid soul where now stood a draculina with a confident aura surrounding her. She had an air of pride and, dare he claim, superiority about her.

Police Girl had become a force to be reckoned with, he could tell, and Alucard was taken aback for a moment.

Integra spun around to glare crossly at Seras, with her one good eye, who still stood in the doorway of her bedroom with her Harkonnen cannon resting upon her shoulder. She had come to Integra's rescue when she heard the gunshots the woman had pummeled into Alucard only moments ago, when he had snuck in here with intent on drinking her blood.

"I suggest you keep your speculative comments to yourself." Integra snapped, her anger giving away her mortification. "And since when have I become a 'mere' human? Is that what I am to you? What nerve! Take that back."

A resonate chuckle came from the vampire still situated on the floor. "Oh, things have changed greatly in my absence. How delightful," he purred playfully. His two favourite women have grown much closer over the years and now squabbled like spoiled sisters.

"Shut up!" They both growled at him simultaneously.

Alucard's eyes widened for a second before he laughed again loudly. He tossed his head back and laughed as if nothing pleased him more.

Integra sighed tiredly, wandered back over to her bed, and sat at the edge of it. All of this excitement all of this noise – the realization of… of everything was so overwhelming. She reached over and snatched up a pack of cigars from the nightstand along with the lighter that rest on top of the carton. With a flick, she lit the thin cigar and inhaled deeply. Then she exhaled a whirlwind of emotions that she tried to keep a reign on.

Seras bowed her blonde head in shame, feeling terrible for upsetting the other woman. "My apologies, Sir Integra, I was only trying to make Master understand your side of things. I…I shouldn't have put you on the spot like that."

Tendrils of acrid blue smoke circled around Integra's long fair hair and she scoffed. "It's alright. I know you meant well, my dear Seras. Let's just forget about it," she offered quietly. It was late, she was tired, and she did not want to argue.

The former police girl let out a giant puff of air in relief. "Well, since we are up and about at this hour and everyone is excited about Master's return, maybe you would like some tea, Master Sir?"

Integra made an agreeable expression. "I believe that is a splendid idea. Thank you, I'll take you up on that offer." The woman went to push herself up from the bed to follow Seras to the kitchen.

"No." Alucard cut in shortly as he got up off the floor. He strode over and stood at the foot of the bed, holding his hand out in a stop-like motion towards his mistress. "I'll retrieve the tea, it'd be my pleasure. I shall return momentarily, Master."

With a mild frown, Integra halted and sat back down with an irritated groan. "Alright then, but don't add too much honey like you usually do… as…" Her voice grew quiet as if in thought and she continued softly, "…as you used to do." She wasn't a child anymore that fancied the sweet tea Alucard used to make for her. It had been a long time since he offered to make her tea, but when she was a child the old vampire occasionally took care of her. Alucard flashed a devilish grin at her before he swept out of the room with Seras looking back and forth between at them. The girl giggled with a knowing blush on her face before she trotted off after her sire.

Seras shuffled behind her master, eyes glued to the back of his old-fashioned long red frock coat with its ruffled shoulders, hardly able to believe he was here and was not just an apparition of some sort. Nope, it was truly him walking down the hallway as if he owned the place. A part of her was nervous and excited, she had so many things she wanted to ask him, things she wanted to tell him, but now that she had the chance, she didn't know where to begin.

Although, what she should have told him first became painfully clear when Alucard suddenly slammed into a wall (which left an outline of his shape in the drywall) with a loud hollow thud. He growled irritably and would have stumbled back had it not been for Seras careening into him like a car pileup on a busy highway. Only it was a vampire pileup in the hallway of the Hellsing manor.

"Oh god! My apologies, Master," Seras beseeched. "I couldn't stop in time."

The walls themselves suddenly gave a noisy complaint with a voice that sounded oddly familiar to the old vampire king. "What the devil?" Alucard sneered.

Seras put a few paces between her and Alucard quickly and adjusted the cannon that rest at her back securely on her right shoulder again. "I guess I should have warned you about the security system I installed all over the mansion before you tried to walk through that wall, huh? I put it on high alert after Master Integra shot at you and haven't deactivated it yet." She offered meekly hoping she didn't provoke an angry ranting from her recently returned master. Even so, she found the entire incident quite hilarious and it was hard to contain a snort of amusement.

Alucard turned to look at her with one raised eyebrow. "You've done this?" He sounded astonished and not angry at all, not even one bit. "You've placed a shadow barrier all over the mansion with the spirit of that snivelling French dog?"

"Hey!" Seras admonished, not even letting Alucard put down the ex-captain of the Wild Geese, a mercenary group hired to help the Hellsing Organization in their missions thirty years ago. "Pip Bernadotte protected this place with honour until the end and he… he was…"

That prevalent grin danced across Alucard's face again and this time it went from ear to ear. "He was your first meal the life blood that made you who you are today, a true vampire. And now, he is your familiar, helping to protect what he cared about so deeply – how very noble of him. It's a guarantee," his voice softened a touch, "that you don't have the walk the nights alone."

It would seem as if her master was as agonizingly blunt as he was thirty years ago. Seras felt her cheeks burn profusely and whined, "Why do you have to say it like that, geesh." Her gaze dropped to the floor.

"Well, how about informing that dog that I am not here for an invasion and let me move about this place like old times, hmm?" Alucard requested. "My master is waiting for my return, after all, and I shan't keep her waiting any longer than she already has."

"Yes, yes, of course. Point taken." Seras gave the order silently and watched as Alucard tested the wall before him with his gloved hand. It phased into the wall without further trouble.

"Is that you, Mr. Alucard?" Pip's voice came from all around them with his cheerful French accent. "Whoa, long time no see, as they say. Although, I cannot say that it is good to see you but as long as I know you're here protecting my mignonette then that is fine with me."

Seras rolled her eyes and blushed again with chagrin.

Alucard grunted insolently in response and continued his journey to the kitchen via the walls versus using the doors and stairs. He felt an odd sense of nostalgia as he took in familiar surroundings, the richly furnished rooms with its aristocratic English air, the long wooden-panelled hallways, fine carpets and wood trimmings, the chandeliers up on the tall ceilings. He noted the plaques depicting family crests, old paintings of rolling countryside's and dull portraits of gaunt-looking old men in their military garb.

It was a stately home suited for a king… or a queen, he mused. It might not have been a castle but it was close to it and it was still home.

"My master has not hired another butler?" Alucard questioned his fledgling.

Seras chewed her bottom lip at the sudden topic at hand. "No… not since—"

"—Walter."

"Right, well… we still have hands like the live-in cook, a maid, the gardener and the housekeeping that comes by once a week, of course. But no, Sir Integra has not obtained another butler which I'm quite sure is properly called a personal assistant or a secretary these days. I really do think she should though since she does so much by herself. Living in this huge house and then there is her work on top of that. She takes on too much by herself. I mean, I do help when I can but I am not much help during the daylight hours when she needs me the most. Even then I'm training the personnel when I'm awake during the day." Seras explained and expressed hotly, "Master, I have never met a more stubborn person in my life."

Alucard smiled coyly to himself. "That's a Hellsing for you… they don't stop until you're dead."

Seras dared with a smirk of her own. "Sounds a bit like you, I should think."

"You're not amusing."

Seras merely shrugged.

"I see that you haven't quite managed to repair your arm yet. Pathetic," Alucard noted. "You have the structure but no flesh and bone. It's a simple spell, I will teach it to you. It might help if you drank blood from the vein again."

It was tempting but she could not do that. "I'd be grateful if you could teach me how to manipulate my shadow powers better. I've learned so much but… re-growing a limb is tough."

It was clear Seras still held on to many of her usual virtues, Alucard thought with a sigh. A vampire still clinging to such mortal nonsense… oh, how different she was from all the vampires he ever knew. She was a special woman with curious strengths, he knew from the moment he saw her that she would make an interesting vampire. He regretted nothing.

When they reached the kitchen and flicked on the light, Alucard looked around the spacious modern room with its stainless steel appliances and raw stone floor. It looked the same as it did thirty years ago. He wandered over to the black electric kettle, dumped out the old water and filled it with fresh before plugging it in again and turning it on.

The younger vampire placed her cannon up against the side of the fridge. "I've never seen you make tea before, Master. I… I didn't even know you knew how." Seras admitted as she walked over, opened a nearby cupboard, extracted Integra's favourite mug with blue flowers on it and set it next to the kettle.

"Just because I'm a vampire does not mean I can't brew tea, I have not forgotten all things human. Who do you think taught Walter how to make the perfect cup of English tea, hmm? Certainly, that smug punk could barely tie his own shoelaces when I met him – that was long before Integra's time, of course." Alucard shared this memory as he found some tealeaves and an immersible sieve, filled it with a level amount of tea, and placed it into the cup.

"It's just…" Seras did not bother to finish her thought aloud unsure she wanted to bother her master about memories of Walter, which was surely painful for both him and Sir Integra. However, surprised to get such an informative reply from Alucard, she thought she would try for something else. "What was it like fighting off all those millions of souls in that… in that place, where ever that was? It must have been horrible."

That is when her sire gave her his creepiest face, his pupils dilating with excitement. "Horrible?" he mocked with a chuff of amusement. "Oh no, it was horribly entertaining. It was like visiting old friends and enemies alike, faces I had long forgot, beasts that I had devoured, a glorious hunt that would not end. The hellhounds' just kept sniffing out more rabbits and more foxes and I just kept killing and killing until… there was utter silence. It was the most perfect silence like that at the end of a great battle."

He sighed with pleasure.

Seras wrinkled her nose. Sometimes she just didn't understand this man, this creator of hers and his profound lust for violence and a good fight. Maybe it was a male thing. "Well, I dunno if that sounds any good at all," she expressed truthfully. "But… but I guess as long as you had an interesting time."

"The only drawback," Alucard added, "Was that I ran out of bullets."

"Oh, now that is a shame." Seras answered sarcastically but Alucard did not seem to catch on to her taunt.

He nodded in complete agreement. "It was."

The draculina watched the ancient vampire wander over to the refrigerator and yank open the door, he peered inside as if considering what to make for supper. Seras grinned instantly. She knew what he was looking for and appeared over his shoulder like a hungry puppy to gaze into the fridge, too. "I'd like some dinner too, please – O negative if we have it."

A breath later Alucard slapped a cold blood pack into her face.

"Um, thanks," came her muffled reply.

She plucked the pack off her face and squished it eagerly between her hands, pleased that he had obliged her with the type she liked best. "Pass me yours and I'll warm them up. Just can't drink the blood cold, it's just not right."

Alucard shrugged, handed her his dinner and watched her as she went over and set the pouches of blood into the microwave. He crossed his arms over his chest as he waited. Ugh, it was an act against vampirism just as it was an act against humanity to cook food in a microwave, he thought. His shoulders slumped a little in defeat though, cold blood was like swallowing old bitter coffee, at least it would be warm and the very idea made him lick his fangs.

He was starving and a meal was a meal.

The microwave announced it was finished with annoying little beeps at the same time the kettle clicked to announce that the water had boiled. The vampire took care of the tea first, pouring the water into the cup and let the tea steep. It would take about two minutes to steep the tea and less for him to devour the blood. He took the donated blood from Seras and eagerly sank his teeth into the soft pouch.

After a few delicious swallows of the warm viscous fluid, he opened his eyes and looked over at Seras who, for the first time, was drinking blood alongside him without complaint. It caught him by surprise and completely mesmerized him for a moment. She noticed him gazing at her and she gave him a crested smile with her own red eyes, squinting at him happily.

A rare glimmer of pride shone in his eyes as he finished his meal with his fledgling – their first true meal shared together. It was a perfect way to start his homecoming, perfect until his thoughts turned to the human woman waiting upstairs for him. Integra, the last remaining Hellsing of this powerful monster-hunting family. She was upset with him for so many reasons, reasons that sometimes felt like a stake through his dead heart. He did not blame her and he wished he could take it all back but those Millennium scum, those fanatical freaks, they came and fucked it all up.

The fun of killing millions of souls was nothing compared to the desire he felt for her, that he would always feel for her. But he didn't think it would be that easy to pick up where they left off, Integra was a mature woman now and he wondered what life's lessons had taught her over the years. Did it make her wiser? More calm. He chuckled to himself, he truly hoped not on the latter.

Seras licked her mouth clean of bloodstained lips and looked questionably up at the other vampire. "What's so funny, Master?"

Alucard raised his head when he was finished. "It's nothing," he said darkly, teeth stained with blood and his eyes becoming redder after consuming the fresh food. His manner was suddenly cold and moody. He brushed past her and went to toss out the empty plastic blood bag into the trash bin.

"O-okay, if you say so," Seras said unsure and cleaned up after her own dinner, as well. She turned to watch her master tend to the tea thoughtfully. He removed the sieve and was now hunting around the cupboards for honey, loudly shutting the doors in his search. Why was he so agitated all of the sudden? It did not take a brain surgeon to figure it out; her master was concerned about Integra. She wandered over, opened the cupboard next to the stove, plucked out the honey bottle, and placed it on the counter.

"Here we are, Master."

Alucard said nothing as he grabbed the honey and finished with the tea.

Seras was not the same timid little girl that Alucard once knew and she was not a cold-hearted vampire. Well, she was cold-hearted in the technical vampire sense because she was undead, but she was not heartless and managed to retain many of her humanitarian principles. So what she was about to say next she hoped would ease her master's restless mind.

"I know you're worried about Master Integra and a lot has changed since you left. Not only has she changed physically and emotionally, but the world has changed, too. I'm sure you'll find out all about that soon enough. If it helps, Master, let me assure you that not a day has gone by—not a single day in thirty years—that she has not mentioned your name. Not one. I never understood until you disappeared how much she really loves you. It must be so difficult for her and it might take time for her to come around. You'll have to be patient."

The old vampire stared down at the mirrored surface of the amber-coloured tea, his reflection absent, and smiled. He produced a throaty chuckle deep in his chest and turned to assess his fledgling in an entirely new light, eyes sparkling with mischief. "My, are you reading my thoughts, prying into this decrepit old mind? Has it given away the deepest and darkest desires of my heart?"

Seras scowled. "Oh, stop being such a toad! I'm trying to be serious here. "

Alucard ceased his infernal laughing but he still grinned widely, impressed with Seras's courage to stand up to him. She may still look like a young woman but mentally she had matured after all these years. "Your concern for Integra's wellbeing is charming and I admit is something very new for me to witness. You have had the pleasure of my master's company longer than I have… and for that, I am awfully jealous. I suppose I should thank you for protecting her while I was detained."

The female nosferatu snapped, "Don't forget she's my master too, you know, just as you are also my master. Sir Integra became as such all the time you were away. I won't let that change now because she is also my friend and comrade." Seras sighed and relented a little. "But you don't have to thank me, if it wasn't for the Hellsing Organization, if it wasn't for Sir Integra I would have had no one and nowhere and, if it wasn't for you… I would have ceased to exist ages ago."

"And this does not disappoint you? I gave you a choice. You do not have regrets?" Alucard wondered even now after all this time. "Are you sure you wouldn't rather be free of this eternal damnation?"

"How is it damnation when I have people I care about around me each and every day? When I can work to protect innocent lives from suffering at the hands of evil monsters with cruel intentions?" For a brief moment, she remembered the hell of her childhood and swore she did not want that for anybody else.

"I was once that sort of monster…"

This time Seras was the one that laughed most sinister. "That's total bollocks, when you get all carried away during field work and whatnot I dunno if 'once' is the word I would choose, I—"

"—the pot calling the kettle black," Alucard pointed out. "The bloodlust is born of the darkness; it can't always be controlled, nor is it any fun to control it. No matter how you say it we will always be monsters."

The girl thought about it, holding a finger to her lip. "I guess you're right but we're still on the side with the good guys. That means something, right?" Seras smiled an innocent smile and was surprised when Alucard came over and patted her on the head in an appreciative way. He did that occasionally and it always took her by surprise.

"You've done well, Seras. I am eager to see what you can do in battle someday. Now, let me speak to our master alone." The vampire king ordered with a gentle voice. "I have much mending to take care of."

Seras was beaming now and fixing her hair that her master had mussed with his pleased ruffling. "Oh, of course," she said. "You won't hear a peep from me. Just remember not to go through the walls with the tea cup or you'll stain your fancy coat and you'll get stuck doing laundry unless you can wait for the housekeeping, but that's not till Thursday."

Alucard put the teacup on a saucer and placed it all on a small tray. He picked it up and headed out of the kitchen. "Goodnight, Police Girl."

Seras blinked a few times.

Heading down a corridor that led away from the kitchen, the No Life King heard a colourful curse directed his way. He knew how much Seras hated that moniker and her reaction to it each time he said it brought him much joy, much evil unadulterated joy.

Seras wasn't finished, her voice carrying throughout the manor. "You're going to burn in hell!"

Alucard laughed to himself. "Amen."

A/N: Merely the beginning of a fun Hellsing'esque kind of journey! Stay tuned for Chapter 2 - The World Hates Vampires.
