Blast from the Past

London was a busy city filled with people that always appeared to be in motion. There never seemed to be a dull moment; streets filled with speeding cars, sidewalks brimming with locals and tourists alike. The hustle and bustle gave the old city life and spirit even when the sun set and the stars came out. But it certainly wasn't a place for people who wished to avoid crowds; people like Hibari Kyouya.

"Stop glaring at the poor bloke," Harry ordered his husband as they walked along a busy side street browsing the various restaurants and cafes. After spending most of the day sleeping to wear off jet lag, Harry and Hibari had braved the chaos of the city in order to find a place to eat. So far they weren't having very much success due to either overcrowding or lack of interest.

"He was staring at you," Hibari growled softly, his arm wrapped possessively around the smaller male.

"Well of course he was, considering our attire I'm not really all that surprised."

It was true after all, the pair were dressed like wealthy businessmen. Their sleek black suits were freshly pressed, their shoes were polished and their dress shirts were the only bit of color on them; Hibari's purple for cloud and Harry's light green for his eyes. They were honestly quite the sight and had turned more than a few heads, both men and women.

"Anyway," Harry continued, "We still haven't found a place to eat and we've been walking a while."

"It's too crowded here," Hibari hissed.

"It's London, what did you expect? Just bear with it for a while Kyouya," Harry said patting the Cloud Guardian's chest.

"Hn."

Shaking his head fondly at the other man, they turned a corner and continued their trek. As they walked, Harry murmured, "We should probably report to Tsuna once we get back to the hotel."

Hibari frowned but made no comment. Chuckling, Harry pressed closer to him, "Plus we need to go over the file his gave us for the mission again. Just make sure we haven't missed anything."

"Will the herbivores be difficult?" Hibari asked.

"Probably," Harry replied, "But the Ministry is easy to handle if you know how to do it correctly. Plus we have all those official documents and papers that Tsuna was kind enough to sign for us. Should Fudge or anyone give us trouble, we can slap them with those forms."

The former prefect nodded. Smiling, Harry continued, "Besides, it's our right to be here. We're hunting down a dangerous criminal who attacked our headquarters. Hence your deployment to hunt him down and punish him. He just also happens to be a wizard which is why our boss decided to partner me with you."

Hibari smirked faintly at the sarcastic drawl at the end of his kitten's speech. And it was the truth. Two days ago, a rogue wizard had broken into the mansion and killed three people in search of Harry. According to Gokudera, who had intercepted the intruder, the man was apparently deranged and had been ranting and raving that Harry Potter was the new vessel for Voldemort.

Unfortunately, despite the damage that the Storm Guardian had caused to the wizard, he had managed to escape before he could be contained. And within an hour of the incident, Tsuna had summoned Harry and Hibari, giving them the mission to deal with the matter. He made it clear that the situation and criminal were to be dealt with by Vongola, not the Ministry. Harry had understood and while Hibari was packing, he used scrying to locate their fugitive. Hence their presence in London.

"Alright we need to pick a place soon or I might gnaw my own arm off," Harry grumbled, his stomach turning as if to remind him it was empty. And a hungry Harry was often a moody Harry.

"There," Hibari pointed ahead where a posh looking restaurant stood, the large windows revealing the dining customers inside.

"Looks good to me," Harry approved.

Of course, it always seemed like Harry could never take a trip to his home country without running into someone from his past. And this time was no different it seemed. Only fate could be a big enough bitch to arrange the situation; the Dursleys stepping out of the restaurant just as Harry and Hibari neared the door. And because there was less than fifteen feet between them, neither party could have missed the other.

Although they looked relatively the same since Harry last saw them over a decade ago, there were a few changes to the Dursleys. Petunia's blond hair was turning more silvery and she had an array of wrinkles decorating her face. Vernon appeared to have gained more weight resembling a dwarf sized planet. His hair was thinning and receding back while his mustache was almost completely grey. All in all, they still looked like a walrus and a horse-giraffe hybrid and of course, they still hated Harry.

The moment their eyes locked, Petunia went pale while Vernon rapidly changed from red to nearly purple, his beady eyes narrowing and his chins wobbling in suppressed fury. It took all of Harry's strength to not sigh and smack his forehead in exasperation while Hibari merely stared down his nose at the couple, clearly not impressed by them.

"You!" Vernon hissed.

"Yes me. Lovely to see you too Uncle Vernon, you look well," Harry drawled, attempting to at least be civil. Because despite how he loathed the Dursleys they were still family if only in blood and it was just best if he was courteous if only to ensure minimal chaos.

"What are you doing here boy, socializing with decent folk?" Vernon growled.

"I'm on business," the wizard replied, his stare bland and unmoved.

"For your freaky lot I suppose," Petunia sneered, her eyes wandering over his appearance. It was obvious this new Harry confused her and made her wary. Gone was the gangly boy whom she had treated like a slave and locked in the cupboard whenever she pleased. In his place was a young, sophisticated looking man of obvious wealth and taste standing next to a handsome young man with cold eyes.

"Actually no, I do have a life outside of the Wizarding world."

"Ha, like any of your lot would be able to work an honest job in the real world," Vernon snorted.

"Yes because apparently you know everything about the world don't you Uncle?" Harry drawled, apathetic.

Glaring, Vernon hissed, "Don't you take that tone with me boy."

"Actually Vernon, I can. I'm not a child anymore and I have no real obligations to you. I've made a life of my own without you in it and I'll happily keep it that way. I merely decided to greet you out of common courtesy, not because I hold any love or respect for you."

Vernon's face once again flushed reddish purple while Petunia sniffed haughtily, as if she smelled something foul. Harry rolled his eyes. Sometimes people just never grew up, his relatives were testament to that.

"Well now that we've had our lovely little visit, if you would excuse us? My husband and I would like to have a nice dinner in this quaint establishment."

"Husband?!" Petunia gasped, a scandalized expression befalling her.

"Yes I said husband. Is your hearing failing you in your age Aunt Petunia?" Harry sneered before turning to Hibari, "Kyouya, meet Vernon and Petunia Dursley, my aunt and uncle. Everyone, this is Kyouya Hibari."

Hibari stared at them coldly in response glancing at Harry, "Hard to believe you're related to these herbivores."

"Yes I know, shocking isn't it?"

Vernon puffed up like a balloon, his face twisted in anger, "Now see here! I will not stand by and allow you unnatural freaks insult us! Your kind think you're so much better than us normal, honest folk because of your… your unnaturalness!"

"Hn, you've got nerve herbivore," Hibari growled focusing on Vernon, "But I doubt you have the spine to back it up. As for your assumption, I'm not a wizard. But I don't need magic to put you in your place."

"Are you threatening us!" Petunia gasped before glaring at Harry, "I always knew you were bad news! Not only are you a freak, but you married a.. a man! And a thug at that!"

"Kyouya is hardly a thug," Harry snorted, "And really you have no right to say anything to me Aunt Petunia. After all, you're no saint despite how hard you try to pretend you are."

"Excuse me?!"

"You heard me. You're an adult, you should have acted like one when I was growing up. You should have known better than to take whatever grudge you had with Mum out on me, a child who was placed in your care. But you didn't, instead you gave into your immature spite and nearly ruined my life. Sleeping under the stairs, barely giving me enough to survive, treating me like a slave; if there is a hell Petunia Dursley than you're certainly going there."

"How dare you! After everything we've done for you, you ungrateful little whelp!" Vernon roared, raising a meaty fist toward Harry. But it never connected at Hibari reached out and gripped the man's arm in a vice clamp, twisting it behind his back. Petunia screamed and a few people stopped to gawk at the spectacle.

"Like I said Vernon, I'm not a child anymore and you can't scare me. I've learned a lot over these years and I've gained a lot as well. I'm married to someone I love, I have amazing friends and a home to call my own. I don't need either of you anymore and I'm glad of it. Once we part from here, take comfort in the fact that I'll never think of you ever again. Even when you pass on, I will not mourn you. Because although we are related by blood, you were never my family and I owe you nothing."

Hibari shoved Vernon away, who cradled his arm trying to remain dignified although it was difficult with his wife hovering around him making a fuss. Snorting, the Cloud Guardian turned to his lover, "Lets go koneko-chan."

"Yes," he agreed taking Hibari's hand, none making a move to stop them. Sparing one last glance at his aunt and uncle, he said, "Goodbye and good riddance."

The pair made their way back down the street toward their hotel, their appetite forgotten. Sighing, Harry took in the musky scent of his skylark who cradled him close, offering stability and comfort. While not really upset over the meeting, it had still unhinged him a bit. He had not expected it and therefore wasn't prepared. But really it was no love lost, Harry thought.

"We'll order room service at the hotel," Hibari stated.

"Sounds good to me. Cause right now I just want to lay in bed with you," Harry murmured.

"I should have broken his arm," Hibari growled, remembering the slurs directed toward his kitten. Very few had ever insulted Harry and lived to tell the tale.

"It's fine, it's like I told them. I'm not a child anymore, they don't have that power over me like they used to. Because I've faced far worse and have come out of it alive," Harry explained, "Besides, their words are just the barbs of petty and shallow people. They have nothing to do with me anymore and I'm happy with that."

"It would have been amusing to see you hex them at least," Hibari smirked.

Harry chuckled, "Well I won't deny that idea didn't cross my mind and it was rather tempting. But not worth the hassle in the end."

Hibari snorted. He'd have to disagree, but he wasn't going to fret over it. It was behind them now. Leaning up to kiss the taller male's cheek, Harry grinned, "Enough about them. Lets just get back to the hotel. I want to eat and then maybe later have some fun under the sheets with my possessive husband."

"Oh?"

"Yup!"

The skylark grinned.

Holy shit I know! It's been months! I'm so VERY sorry! My motivation for this story was at zero despite all the ideas I still had left. But suddenly it's like BAM! Theo wants to work on it and I wasn't going to look a gift horse in the mouth. So here we go! Another chapter to show that I (and this story) are still alive! And GASP! I actually wrote out more chapters after this one. And I'm still going! So I hope to keep up this wonderful pace so that you, my loyal and patient readers, get to enjoy yourselves! Because you deserve to be spoiled for being so amazing.

Anyway! I really hope you liked the chapter! Drop me a review because you know I love your support and I love you guys because your'e awesome!
