Surprisingly enough, I had this idea in my head for the whole day so... yeah, new fic. Also, it'll have slash so haters, beware !
What else... It'll be a little AU but not to much (it would ruin the fun) and a threesome. Maybe. If I feel like it.

This is all, enjoy ! ^^

Death was a simple thing if you were to ask Harry Potter.

One moment, you were battling against the rising new Dark Lord. And the other, you were, well... dead.

Harry blinked as he slowly gazed at the row of seats disposed in front of the railways and he sighed.

"This is it, I guess," he muttered while he walked in the empty King Cross Station.

The wizard smiled and stretched with a good laugh, finally free from all the responsibilities that came with being the Boy-Who-Lived.

"Finally," he exclaimed as he began to run in the void corridors of the station. "No more brat to teach! No more Dark Lord to defeat! I'm utterly free!"

Harry stopped his run and looked at the panels that were hanging at the hall station. Or at the man who was quietly sipping his lemon tea while sitting in one of the pubs.

"Professor Dumbledore? I didn't expect to see you again..." said the raven as he sat in front of his deceased director.

"Oh, Harry..." the old wizard answered with a familiar twinkle in his blue eyes. "You can't expect everything in this world. But I have to admit that I was surprised. This café has the best lemon tea that I have drank in my life."

The recently deceased male blinked.

"But, aren't you dead, professor?"

"Ah, I wonder," Dumbledore admitted with a knowing smile. "Am I dead? Or am I a hallucination? We already had this conversation, my boy."

"Right. Then, what brings you here, Professor? I thought that I was dead and there isn't anymore Horcruxes."

Dumbledore drank another sip of his tea and set down his cup on the pub table. Then, he looked at Harry and the younger wizard arched an eyebrow when he recognized his director's expression.

"No," the raven said quietly. "There was a prophecy, I'm not the man who will defeat that new threat. If anything, it's that brat mission! There isn't anything that ties me to the living."

The older man smiled and cocked lightly his head.

"Ah," he whispered. "I believe you're talking about the young Angel, right?"

Harry groaned and made a exasperated expression.

"Really," he uttered. "They should have named him 'Devil', it suits him better! That brat was the most stupid and aggravating fool that I had the mishap to meet..."

"You sound like Severus when he was talking about you," commented Dumbledore while the twinkles in his eyes strengthened.

"Yeah, I'm beginning to understand the torture he had to live... And the worst! The worst is that I died to save that brat..."

"Right. Like Severus."

Harry rolled his eyes and sighed again. He lifted his hand and conjured a glass of Firewhiskey. Dumbledore raised silently his cup of tea and they drank quietly.

"What now?" the raven asked as he put down his empty glass. "Do I have to board a train to go to the next stop?"

His former director frowned and shook his head.

"I'm afraid that you'll have to wait, Harry."

"Why?" cried the wizard. "I'm really tired of the Wizarding World! And don't make me talk about that twit..."

Dumbledore laughed gently and lifted his hand to take his wand. He made little movements and Harry observed him in silence, his green eyes darkening as he pondered over his remaining choices.

"To go to the next stop, like you said, you have to be freed of whatever connections to the living world. The thing is, my dear boy, that, like the poor Tom, you've a soul connection with someone."

The silence in the spooky King Cross Station strengthened as the raven wizard opened his emerald eyes wide.

…

"WHAT?!"

Dumbledore made a light smile, understanding without problems the panic that submerged his former student and waited. When Harry was finally calm enough, the older man explained the situation.

"It is not like you've a Horcrux," At those words, a relieved sigh sounded in the station. "But you've a soul bond with someone. And, as that person is alive, you'll not be able to cross."

"Great," muttered darkly Harry. "Just great. So, I have a bloody soul bond with a stranger. Couldn't be better!"

"Well," smiled Dumbledore as his blue eyes sparkled with diversion. "It could have been the young Angel..."

Harry groaned and put his hands on his head.

"Please, that would have been a nightmare," he moaned. "I would have been forced to assist at all those stupid things that brat does..."

Suddenly, the raven perked and his green eyes looked at his former director.

"Don't tell me that I'm now a angel guardian thing..."

"Oh," laughed Dumbledore. "You aren't nothing of that sort, Harry. You're just soul bonded to someone. That is all, my dear boy."

"Yeah," the wizard said reluctantly. "And that soul bond thing consist on what? Do I have to mate that person? Or is it something else?"

"Well, you could mate that person, it is true," admitted the professor. "But you don't have to if you don't want to, Harry. You are free to choose. Also, the only thing you need to know is that that person is almost like a part of your soul. You could say that you're soul sisters.

"Ah..." the younger deadpanned. "And what have I to do?"

"Just be next to that person," answered Dumbledore. "That would be enough."

Harry nodded slightly and stretched his back.

"So," he resumed. "I only have to be next to that person and all that jazz, right?"

"Also, you've to know that if that person dies, you'll die immediately."

"Fantastic," Harry whispered with sarcasm. "I love my life..."

"Isn't it exciting, Harry?" Dumbledore asked with a knowing smile. "To be able to travel to a new world and be next to your soul sister... Aren't you a lucky boy?"

"So exciting that I'll faint," the sorcerer said with a wry smile.

"Well," chirped the former director as he stood up. "Until the next time, Harry!"

The Survivor opened his emerald eyes wide and rose as he began to run to his old mentor.

"WAIT!" he shouted. "A NEW WORLD?"

But before he could catch Dumbledore, the floor began to melt and Harry swore as he was swallowed.

Of course, death couldn't be a simple thing if you were Harry Potter...

The Boy-who-lived cursed like a sailor and closed his eyes when he saw a mouth-like thing approach him.

'I though that I would have to board a train to go there... Not to be swallowed by a monster' ruminated the wizard as he was absorbed in the mouth-like thing.

And it was like that that Harry Potter disappeared from the Wizarding World and appeared in a completely different world.

[...]

"Ouch!" Harry complained as he fell on something hard. "That went better than I expected..."

The wizard stood and observed silently his surroundings. He was in a cell (if the bars on the window weren't obvious) and there was a little bed made of dirty sheets on the floor, next to what seemed to be a bucket to release himself.
Also, the cell was filthy as hell and reeked of blood.

Harry pinched his nose and pouted. Why did he have to appear on this filthy cell of all the places in the world? But he forgot quickly his complaints when he heard a small whimper. The wizard whipped his head where the sound came and arched an eyebrow when he saw a glimpse of hair in the makeshift bed.

"Hey," Harry called without moving as he didn't know where he was or if the other person was dangerous. "You OK?"

The whimpers stopped and the raven frowned slightly. He didn't like one bit the silence that followed.

Suddenly, the dirty sheets of the makeshift bed flew in the airs and the wizard tightened his hold on his wand. Then, a hand ripped the sheets and headed for Harry's neck. But the former Survivor was prepared and braced himself for the impact. When the hand touched his neck, the wizard lifted his wand and casted a Stupefy to stop his enemy.

The sheets slowly landed on the filthy floor and Harry widened comically his eyes when he saw his opponent.

"For Merlin's underpants," he muttered as he observed the little body paralyzed on the ground. "What the hell is going on..."

The heterochromatic eyes of the little boy stunned looked at him without answering anything and Harry groaned as he carved his hand through his hair.

"Are you kidding me?" he added while removing the spell. "A kid in a cell... What the hell did you do to end here?"

The child blinked slowly, regaining progressively his motor functions as the wizard continued ranting.

"Also, you're skinny as hell! Do they even feed you?" Harry said and he quickly metamorphosed the dirty sheets in a pristine bed. "Merlin, it's not surprising that you were trying to kill me! Even I would have!"

The kid didn't answer (not that Harry was expecting one) and watched attentively the wizard's rumbling as he casted spell after spell to clean the cell.

"There!" the raven said with satisfaction. "Now you can call this a cell! Even Voldemort had better courtesy and that's something as this bastard liked to put his prisoners with a werewolf on a full moon..."

The floor was now in a dazzling white and the walls were covered with a warm wallpaper with moving pictures. Also, the bucket had been transformed in a toilet and even the bars were cleaner than ever were. The child noted all of this and gazed silently at the raven male who was now busy observing the corridor from in-between the bars.

"How did you do that?" the young asked.

Harry arched an eyebrow when he heard the small voice and turned his head to the kid who had sat himself on the new bed. The wizard noticed that the kid had strange indigo hair who was shaped like a pineapple and different eye color before he thought over his answer.

"Magic," he decided to say.

"Magic doesn't exist," retorted the child with a deadpan expression.

Harry snorted with amusement and began to play absentmindedly with his wand.

"Then, how did I do that?"

The kid watched with fascination the stick turn in the stranger's hand and frowned.

"How could I know it?" he spat.

"Then it's magic," concluded Harry with a wide smirk.

"Yeah, right," the young muttered. "Like hell it's magic... It must be some trick... Or illusions."

"Well, tricks and illusions are a lot like magic, don't you think?"

The kid made a grimace and didn't answer. Harry shrugged and looked again at the corridor.

"So, what did you do to end here?" he asked nonchalantly.

The kid shivered lightly and glared at the wizard.

"Doesn't concern you," he snarled aggressively.

"Well," Harry began as he shrugged again. "I appeared in your cell so I think that you're my soul brother or something along. Therefore, I think that it does concern me. So, how did you end here?"

"Soul brother?" the kid repeated with incredulity.

"Doesn't matter"

"Well, if you doesn't explain yourself, then I won't answer..."

"Let's just say that I was sent here by an old friend to be with you. That's all. You're next."

"Family sold me to the Mafia. I'm an experiment's subject."

Harry whistled with amazement and pushed lightly the bars. They clanged loudly when they fell on the floor and the wizard broke out with a little smile.

"I see," the raven said as he looked at the kid who was still sitting on the bed. "That's too bad. It must be boring too."

"Boring as hell when they don't torture me with their experiments."

Harry looked at the empty corridor and sighed silently as he weighed his options.

"Hey, kid," he called. "If you had the chance to leave, what will you do?"

The child smirked evilly and slowly stood.

"Isn't it obvious? I'll take revenge."

Harry laughed loudly and took the kid's hand.

"You're like a mini-Voldemort, do you know that?" he chirped with twinkling eyes. "By Merlin's socks, it almost makes me want to adopt you!"

The child frowned and quickly released his hand from the wizard's grip.

"I'm no kid or mini-Voldemort," he hissed. "I'm Rokudo Mukuro. And you can't adopt me."

"Oh?" Harry raised his eyebrows and folded his arms. "And I'm Harry Potter. But that doesn't explain why I can't adopt you. Also, you're damn cute, Rokudo. Did you know it?"

"Firstly," Mukuro lifted one finger. "I'm not cute, remember that, Potter. Secondly, I don't want to be adopted. Especially by you."

Harry pouted and waited patiently as he saw that the child had lifted another finger.

"And thirdly," finished the young. "A kid cannot adopt another kid. Especially when he's younger"

The wizard widened his eyes in surprise before he quickly conjured a mirror. Then, his bright green eyes darkened as he slowly took awareness of his new appearance.

"Why me..." whined the six years old wizard as Mukuro smirked. "Why is it always me..."

Well, the next chapter will be when I'll finish it. Don't know when to be honest ^^"

Why don't you leave a review to encourage me to write ? （ΦωΦ）
