IX: Of stories and house cleaning: an intro

Harry groaned, as he raised himself from a luxurious and sinfully comfortable four-poster Queen Sized bed; with a mattress that seemed to mould perfectly to his body and his sleep patterns. As he sat up, an arm reached across his chest and pushed back down "Stay still, I'm comfy." Came a murmured voice from his side.

"I'm exceptionally hungover…" Harry groaned, he twisted his neck relishing the feeling of the cartilage in the joints popping and cracking. As he settled down, he jerked slightly…he was definitely under-dressed and it felt like he'd sweated a lot during the night.

Harry looked at the arm. It was milk-white, almost alabaster and quickly found a mass of dark blue almost black hair on the pillows next to him. "Ak…Akeno?"

The Thunder Queen of Rias's peerage raised her head "Fufufufu, morning Harry." Her throat and raspy as she spoke, it sent tingles up Harry's spine and to make matters more intense she was completely naked. "Like what you see?"

"Don't you know it." Harry replied this time standing to get out of bed, only for his legs to fold from under him and he landed with a crash on the floor. As Harry hit the floor, the door opened and Rias, in a translucent nighty rushed in.

"I just heard a crash…You okay, Akeno?" Akeno blushed slightly, however as red as Akeno went; Rias went far brighter red as Harry slowly pushed himself to his feet.

"That was me, Rias." Harry, was very easy on the eyes. Despite his towering height and wiry frame, right now he looked horrible "What was the damage? Did I do anything?"

Rias giggled "You got drunk, hit on several heiresses and vertically suplexed my cousin Sairaorg…He's fine, more surprised that you were able to do such a thing whilst intoxicated…Sona might have more details."

Harry shrugged "Anyway, where am I? Where are my Godfather and Uncle?"

"The three of you are currently in the Gremory Residence. You, are in my Wing of the House where my Peerage and I reside whilst in the Underworld. I believe your Godfather and Uncle are about to head to breakfast, the same as us."

Harry grunted "Whatever was in the Mead, it's wiped out my sense of balance and direction."

"That would be Leviathan-sama, she challenged people to drinking…Don't worry, she came off worse." Harry turned faintly grey.

"I challenged Foreign Affairs to drinking and won…"

Rias was grinning more so, she knew exactly what Harry had done and was taking immense satisfaction in dropping him in it "You've also sworn yourself into an interesting bunch of contracts between Gremory, Bael, Sitri and Phenex family in essence you're offering your services for a dozen fights a piece with a physical presence in a quarter of them…However, you've also sworn yourself into mine and my brothers services…"

"Didn't a Liverpudlian scam three Arch-Duke Devils into curing his lung cancer and let them go to war over his soul?"

"You don't want to bring it up with the Agares, Vassago's or Amon's…Why?"

Harry smirked "So the Hellblazer Comics have some grain of truth to them? Anyway, I'm off for a shower and you're welcome to join me."

"Through those doors on the left…Help yourself to a towel." Akeno replied watching Harry's ass move away from her.

As the door closed, Rias turned to her closest friend and surrogate sister "You like him don't you?"

"Can you not blame me? You can see it in his eyes, he has zero damns about…outside circumstances…You like him as well?"

Rias looked Akeno in the eye "As a friend…Nothing more. As Heiress to Gremory and your sister, I speak the truth. Honestly, I'll be happy once Sirzechs releases him from their arrangement. He's ridiculously powerful, pulls so many hairbrained schemes out of his sleeves on the fly…he's almost too good to be true. Giving him instructions and orders during a Rating Game is something that I can't cope with. I can't tell this to Harry's face for I fear he'll laugh, I misread him…I thought I knew what I was getting into with him but I didn't."

Contrary, to what Rias thought Harry wasn't listening. He was instead standing under the hot water. The water felt so good, after cleaning himself up. He wrapped a towel around him and left the bathroom to see Rias leaving. "Everything okay?" Harry asked as he pulled on a set of clothing with his name on: a pair of jeans, a red and black flannel hiking shirt and a pair of socks to go with the slippers that were customary to be worn inside.

"Harry, have you got any plans after breakfast?"

"Get my Guardians home and…anime binge or workout."

Akeno giggled "Would you want to come and visit my Shrine? Also could you help me with lightning and thunder magic?" She finished with an exaggerated movement allowing Harry to see all of her body.

"I'd be honoured…Akeno, I have to ask what's up with this…"

Akeno looked at the Magician and tears began to well in her eyes. Harry was next to her in a moment, pulling her into a hug "Hey, hey, hey now…I'm sorry…"

"It's not you its me…" With that Akeno tried to break away from him but even her hybrid status with a naturally enhanced strength couldn't break out so easily. "You've got something to say, I'm willing to listen. Go have a shower, and I'll listen as you talk."

It took forty-five minutes but eventually Harry and Akeno made their way down to breakfast. They were the last to arrive and the rest of the family had just begun to eat "Harry, my boy, where were you? You were in full party mode and then suddenly you'd gone." Sirius exclaimed giving him a hug.

"I'm missing the hours between two and five, I think. When did Serafall start the drinking competition and Rias: When did I suplex your cousin?"

Rias choked slightly on her juice however it was Zeoticus who spoke "That was about two-thirty when Lady Leviathan started the drinking competition. You joined us until nearly four when Lady Leviathan went unconscious. You then foisted her off onto her Pawn shortly afterwards. Sairaorg was well into his cups, when he challenged someone to knock him over…"

Harry nodded "More importantly despite how mangled I got, I apologise most profusely for tying up your house with lawyers, legal teams and counter legal teams for my services."

"Nonsense; it serves us right. We're Devils we are meant to be opportunists and hedonists but you outsmarted us. Once we've sorted out seniority then you can start the contract."

"I'm surprised you haven't immediately done the 'possession is nine tenths of the law'…" Remus pointed out "Your eldest, brought Harry in to assist your daughter get out of her betrothal."

"Wouldn't work, at best it'd cause civil unrest at such blatant disregard of power. At worst it'd cause a civil war and kickstart the old war." Millicas chimed in.

"Mr. Lupin, my father is Lucifer…it's a title. Anyway, point is…He cannot directly interfere with this despite him already interfering more than he has. My fathers hands are clean in this regard; Devils consider Humans fair game, and thus Lucifer making contact with a human mage is not something too out of the ordinary, and all my father did…"

"Was give me the suggestion and option with the reward being a favour- to be agreed upon by myself and Sirzechs within boundaries." Harry finished.

"100% Human meddling in this. Anyway, this is delicious." Harry stated. Normally most people couldn't be tempted by food with a hangover, but Harry had a cast-iron gut. As long as he picked the right the food, he'd be fine.

Eventually breakfast finished Rias looked at her assembled team "Everyone, let's head back to the OCR and await further instructions."

Harry nodded, rolled his shoulders "Sirius, Remus?"

The two got up "Thankyou for your hospitality." Harry said as he laced up his boots.

"We could give you a lift to the surface…" Rias began.

"I've got my own way…" Harry replied as he grabbed his guardians. "Phoenician Mantle!" Then in an orb of fire that left a warm sensation in the dining room the trio of wizards were gone.

Zeoticus snorted "Rias, you do know how to pick them."

The Wizards arrived back in their apartment, the mantle fell off Harry and vanished. "I'm getting a drink, charge my phone and then go and see Akeno."

(Sidestep to Britain)

Ever since, that fateful duel in the Atrium. Ever since Harry had destroyed Voldemort in clear view of everyone; the impact of that simple action had reverberating repercussions.

Cornelius Fudge had been swiftly removed from power, put before the Wizengamot with Amelia Bones at its head doing a 'by-the-letter-of-the-book' trial and the usage of Veritaserum, Fudge was spilling his guts and blabbered about the bribes, the laws he passed etc. Fudge knew he was gone and the only way out was to name names.

Delores Umbridge, was one of the first to go. Due to her duration as Tyrant of Hogwarts; almost every student who had experienced her as teacher and those who had suffered in one of her detentions wanted to help send her down.

Unfortunately, none of the charges were going to stick. Because as brutal as she was, she was unfortunately rather clever. Only two people had been knowingly tortured with her infernal quill and they were Lee Jordan and Harry Potter. Lee Jordan, a half-blood of a newly created wizarding house and as a result had very little political clout to bring against the Toad.

That meant the only person who could bring any sort of charges against Umbridge, was Harry Potter. Amelia Bones looked at the list of charges against Harry Potter and Sirius Black. She was stuck! "Send a summon to Harry Potter and Sirius Black."

(Back in Japan)

Harry appeared with a crack fifteen metres at the boundary of an old Shinto Shrine. The wards here were exceptionally powerful, even not at their peak.

Harry slowly and confidently walked into and through the wards and slowly began to climb the stair. Akeno met him at the top; dressed in an outfit eerily similar to that of the a Shrine Maiden, it looked good on her. Unfortunately; the Hybrid Priestess of Thunder and Lightning had a physique that made anything she wore look amazing on her. This wasn't a flirt or even a phrasing to make her blush; but in Harry's own humble opinion this was a fact.

Akeno reached out with her mystical senses and found Harry's aura beginning to twist and twitch, like a caged beast, surrounded by the power of the wards of her second home. "Please, Harry be welcome." With that phrase, the writhing mass of magic subsided.

"Inherent domain magic, you hadn't formally welcomed me…It's very effective against intruders. If we'd fought, I'd have been hard pressed to beat you." Akeno giggled.

"So the all powerful contract wizard of Gremory, bested by Shinto Wards."

Harry nodded "I have to say, I like it…If not for the slightly ominous feeling of should we spar; these wards will hit me akin to a freight train…Painfully. Also, why here?"

Akeno looked at her secret crush and unfurled her wings "This is me. A living paradox; a Shinto Shrine Maiden by heritage, alongside a Fallen Angel and converted into a Devil…"

"I live with a convicted mass murderer and a werewolf. I have the armoury of the Native Britannia Gods as myriad collection of pseudo-Longinus, multiple balance breakers and sub-balance breakers AND I have the offspring of the Y Ddraig Goch; as my families permanent reincarnation spirit slash host slash avatar, all because one of my ancestors swore a pact with it. I'm also a member of Nobility due to multiple inheritances…I've still not got through the paperwork and I've caused a massive legal flustercuck of four houses in the Underworld and Duke and Duchess Gremory are laughing at the absentminded chaos…So yes, Akeno Himejima we both live in glasshouses and should not throw stones…In fact, I shudder for our descendants."

Akeno couldn't help giggle at that "You do know that Hybrids, Fallen Angels, Angels, Devils and Demons have…problems with fertility and reproduction which is why Riser and Rias were betrothed."

"Aren't most supernatural races? Besides you can't be as bad as Wesen."

"Wesen?"

Harry snorted "All humanoid creatures that have an alternate guise of some sort of creature…They're good people, majority of the time."

Akeno, ever curious about the supernatural grabbed Harry's hand and pulled him into one of the houses. This one was in better condition than the others and soon enough Harry was drinking a sinfully delicious cup of tea. "Wesen…Have you heard of the Brothers Grimm?" With that Harry went on to explain Wesen.

Akeno's eyes widened, she knew that the supernatural world was vast but coupled with the Magical World that Harry walked in, but this was new to her. "You think you'd be able to introduce Rias to some?"

Harry snorted "Maybe, but I wouldn't be the best. Due to my magical abilities, I have a self-reflective woge…I woge when I see others woge, plus I'm what could be classed as a Zauberbiest…and we're not liked at the best of times. Hexenbiests, Zauberbiests, Witches and Wizards are fucked even by Wesen and Supernatural standards. We can be born and created, I don't know much about it apart from my Paternal Ancestry stems from a Born Zauberbiest; the Woge has watered down to the point of self-reflection and my mother was a new-born Witch and a powerful one."

"What did you inherit from the Zauberbiest of the family?"

"A certain ruthlessness and lots of power, oh and some Sacred Gears."

"And your mother?"

"Magical power and some Sacred Gears."

Akeno giggled "In your own words a train wreck."

Harry nodded "Yup. Now I have questions about you. These deals and contracts you make, please tell me more."

"Okay. Rias as King; only accepts requests which are few and far between and they have to be worthy of a High-class devil…removing curses and defeating monsters."

"Mine are normally bosses of major corporations and or there wives. Mine mainly revolve around de-stressing people by listening to them and performing tea ceremonies…Little things to make others days better."

"Koneko and Asia are more playing cards with people and cosplaying." Harry nodded with a grin on his face.

"She does have that inherent cuteness to her…But, I have a feeling I've annoyed her and she'll gladly put me through a wall."

"No, she just thinks your brainless wizard with too much power and little sense."

"She's got the jist of me…Anyway the rest?"

"Kiba surprisingly is a decent cook and helps older women de-stress…Not like that, but wouldn't surprise me."

"Issei is the weird one and enough said." Harry snorted at that, the Red Dragon Emperor was definitely a little weird, too weird to be healthy. Then again Harry wasn't exactly one to talk considering the party.

"Anyway…what is it that you want to do?" Harry asked.

"Have you ever been around Tokyo or even around Kuoh?"

"I've never been anywhere aside from Hospital, School, Home and the Underworld…You show me; it's on me."

Akeno grinned just as a Gremory sigil appeared. "Harry…"

Harry summoned Dyrnwyn with a barely a thought, the orange flames taking on a blueish tint. Fortunately for them, it turned out to be Rias "Akeno…I need you at the OCR. Harry, I'm…going to need you as well and well…your connections and books."

"Magical power and casual whimsical nature." Harry chimed in. Rias nodded and the three of them headed through a teleportation sigil. The OCR came into view, surprisingly Sona and Her Peerage had arrived. Genshirou jumped off the couch as Harry entered and flopped on it.

"Harry." Sona stated.

"Sona."

"How's the hangover?"

"Non-existant…What's happened now that Rias needed my presence."

"You're her Pact Magician, when she summons, you answer."

Harry sighed "Fair enough…Still point remains; what's the crisis."

"Leviathan has contacted us, saying that her counterparts in Rome have dispatched two Exorcists to investigate claims that the Underworld have stolen the Excaliburs." Sona explained.

The Peerages were shocked, even Harry was momentarily taken aback "Rias?" The Redhead nodded and Harry apparated out with a boom.

"Where's he going?"

"To find something in his Library."

(The Library)

Harry arrived in a boom, effortlessly ducking a hurling hex from Sirius "Sirius, where is the…" Just then an impossibly large book came flying towards Harry, the book was black and made of leather and was impossibly thick.

On it the title read 'The Truest Fates of the True Swords'. "Why'd you need that?"

"Something that is about to make Kuoh an unstable place to be."

Sirius nodded "Unfortunately these have arrived…We're going to be needed back in Wizarding Britain."

"When?"

"Remus has booked us a First Class plane for tomorrow…You're going to need to wrap this up quickly."

Harry nodded and vanished in a plume of fire.

(OCR)

"Back, anyways Rias…shit's gone sideways at home in the most spectacular and typical inbred political fashion. So, Saviour Harry has to go and wipe the collective arses of those in charge…Anyway, let's have a look."

"The Truest Fates of the True Swords?" Sona asked looking at the Title.

Harry shrugged "Fucked if I know, Sona…Fucked if I know. Anyway we're looking up Excalibur right?"

Harry opened the tome and began pouring over the pages "Huh. Okay, Excalibur wielded by Arthur, King of the Britains, Once and Future King…Yeah, yeah, everyone knows that. Okay on the Fields of Camlann where Arthur and Mordred fell, Excalibur was broken…Bran and Qrow Potter were slain trying to protect the sword but when they died the blade once whole became seven: Destruction, Mimic, Rapidly, Nightmare, Transparency, Blessing and Ruler…It seems the Potter's managed to save a lot of the Round Table Swords…Pity, we were almost wiped out by what would now be named the Christian Relgion; cunts one and all and they took six of the seven: Destruction, Mimic, Rapidly, Nightmare, Transparency and Blessing."

"What happened to Excalibur Ruler?" Tsubaki asked, cocking her head slightly.

"Elaine, Eldest Daughter of Harald and Gwynneth, House Potter, eldest daughter of the second son, now Clan Chief…Yeah, returned it to House Pendragon…I'll deal with that later." Harry looked up.

"Questions?"

Issei raised his hand "Why are would the Church ask us?"

"Simple, you're all Devils…Destroy all Devils etc, pretty much the religious slurry and dogma that spews out of the Church as an Institution. Pretty sure that the Subject of the Bible is big on redemption, acceptance etc…So in all honesty, this screams trap and set up."

"What would you recommend?" Genshirou asked.

"Keep your heads down, consume Sitri mead and wait for this to blow over…considering this isn't a Zombie Scenario, not the best idea. Honestly, suck eggs and deal with the Exorcists…Who knows the true brains behind this might turn up so the Magician recommends, hone your strengths, strengthen your weaknesses. Sona; you know yours best. Issei…get good and fight smarter, oh and your contracts work on your deal clincher.

"And me?" Rias asked, a smile on her face.

"Just be you…Anyway. I shall see you soon. If anyone in the school asks for me tell then 'broken ribcage, cracked femur and diaphragm haemorrhage…I'm an adrenaline junky."

With that Harry grabbed the book and vanished. Soon enough Monday rolled around and by 8am, Kuoh Time the three wizards were on a plane heading back to England.

(England)

They made it. They were jet-lagged and sleep deprived but they were back in Britain. "Sirius, can we get this done for tomorrow and then fuck off again."

"That we can. Although, they're probably…"

Harry's eyes began to flash like lamps "They try anything, I'll finish what Tom started."

After a hazy day, of recovering from Jetlag and a few bottles of beer. Sirius and Harry got dressed in formal robes, Harry summoned Curtana; sword of justice with one edge blunted and the other sharpened and placed it inside Cel.

"Remind me what the plan is."
"We make peoples days painful. If they comply only marginally less painful."
"Fair enough…" With that the youngest Heavenly Dragon faded away to the subconscious of Harry's mind, to the point where Cel was able to converse with his previous wielders. Out of all of them, Harry so far was the most adventurous having unlocked the Scale Mail and the Overdrive; his version of Ddraig's Juggernaut Drive. Cel internally rolled his eyes, however Harry's ancestors had different types of magic that Harry hadn't learnt and Cel was not about to risk his latest wielder succumbing to the inherent rage of the Potters. There was a reason behind that infernal curse after all!

"Once he gets his head on straighter, then maybe I'll introduce him to his ancestors…You, Potters are most certainly an entertaining bunch."

Harry and Sirius made it to the phone booth, typed the number in "Welcome to the Ministry of Magic, please state your name and business."

"Harry Potter, House Cleaning."
"Sirius Black, House Cleaning Hirer."
There was a dispensation and the two badges appeared, they grabbed them as the doors opened. They were met with the presence of Aurors everywhere and guarding the gates alongside the security guards were people dark green robes and black dragonhide.

"Aurors and Hit Wizards; seems whoever's in charge isn't fooling around. Even the backchatting, barbed banter between Aurors and Hitwizards isn't occurring."

Harry cocked his head "Aurors are like the Police, Aurors are more Armed Response and Militant types. Aurors need dispensation to use certain parts of their spell repertoires whereas Hit Wizards only need clearance for only the most brutal or martial magic. Then there's the heavy water-filter chat in the Aurors that Hit Wizards are more mercantile and more prone to enthusiastic ways to gain information; things that Aurors aren't allowed."

Harry nodded "Coppers and Armed Response, in other words let us not be stupid…" Harry turned to his Godfather "…Is it a bad idea to contact Rias and let the Mundanes know of people willing to hire their services."

"Selling people to the Devils…That's not a bad idea…Almost Marauder worthy."

Just then he walked right into someone, a dark brown eyed and haired person "Hermione."

Hermione spun "Harry!" She yelped before repeating it with a squeaky hiss "Harry?" Harry nodded and before he knew it, Hermione had wrapped her arms around him.

"What are you doing here?" She whispered.

"To deal with Umbridge and formally stuff any offer the Ministry and Wizarding Britain back at their faces. Oh and to make you an offer."

Hermione cocked her eyebrow "That is?"

"Paid researcher for some…shall we say…Interested Parties who might see the Wizarding World as a resource. Everyone will be given equal hearing or perhaps more so if I've referred you."

"Harry, this sounds dodgy even for you…What are you involved in?"

"I may or may not have found out that the Ars Goetia is accurate, and I'm working for an extremely beautiful, book smart but slightly naïve or seemingly naïve red-headed Devil Heiress and her attractive subordinates."

"Who are all female?"

"Male as well, more heavily female also known as the 'Downed and the Out'. Quite literally, they've joined her because they've either no-where else to go or death."

"Quite the bleeding heart…Let me get this straight, you work for Devils and you want me, your best friend, to sell my soul with you and join you. What did they offer you?"

"No claiming on the soul. They may be heavily roman influenced, but they're not savages. They have standards. That's Hell…The Underworld is utterly different."

Hermione cocked her head to one side "Prove it."

"Yes, yes. Come to Grimmauld when we're done here…I'll ring the boss. She'll come when I call. It's an interesting relationship, she doesn't give me orders only heavy-handed suggestions and I…"

"Occasionally listen, but listen better when mass mayhem and pandemonium are on the table…Harry, I love you dearly, but, you are the most self-destructive, selfless, annoying but loveable little brother I never had. So, I can safely say she enticed you with mayhem and pandemonium."

"That was her brother, Lucifer…My debut service was to help her get out of a betrothal."

Hermione face-palmed "Padma is going to kill you, for getting me involved…But the pair of you come on."

Throughout this conversation, Sirius had managed to keep his and Harry's heads down. That was until they reached the Desk, Sirius handed his wand over "Fourteen Inch, Ebony, been in use for 26 Years belonging to Sirius Black."

Sirius swore and the Hit Wizards and Aurors were upon him "Sirius Black, you are under arrest…"

With that everything went mad.
