This is my first story on this site. I have always loved KHR and OP so it's my dream (sort of) to write a crossover of these two wonderful animes. Hope you guys like it!

Please like it if you enjoy the story and comment if i have mistakes or something. The story will be slightly different from cannon at some points.

Please also note that English is not my first language so there will be wrong grammar, but i will try my best.

The first thing he noticed upon reaching consciousness was the constant sway of the thing he was lying on. It was probably a boat, he concluded, feeling the hard surface of wood against his back and a faint sensation of what felt like small waves through it.

'Where am i?'He thought, slowly rubbing his temple to ease the throbbing headache. His whole body hurt like crap, the dull pain all over the places made it even harder to think clearly. His foggy mind slowly drifted to the last memories he had, the sound of guns, the smell of gunpowder, the acute pain in his chest, the feeling of blood flowing down, the cries of his family, the shocked and terror-filled eyes of his friends...

He was dead.

Dead by a mere bullet, dead by a second of carelessness eventhough he had been through hell and survived (Technically, Reborn's training was hell itself). The feeling of guilt seared him as he remembered the pain on his family's faces when they gathered around his moribund body, calling out his name, begging in hopelessness for him not to die, not to leave them. A heavy sigh escaped his lips, 'At least i won't have to worry about their well beings in the battle, it's almost the end of it anyway' he reassured himself, not that it helped much with the creeping guilt he was feeling.

Now that he knew about his supposed death, the next thing to find out was his whereabouts. For a second there he even thought he was applied to some depraved customs of letting corpses floating on rivers, but quickly disposed the idea because dead people couldn't be... well, alive to be aware of their surroundings. This brought up another question as to why he was still able to think. 'This must be the mythical river of hell that Mukuro was telling me about' he thought, nodding to himself with certainty. The idea was absurd, but it was the answer best fit in this situation. Something in his mind was screaming about this whole river thing being ridiculous, but he just ignored it for now in favour of enjoying the last mythical ride of his life.

Or so he thought...

Poke...

The sudden feeling of something poking on his head and body were unnerving. He wanted so badly to just swat the thing away, but remained still when he thought about what, or who could be poking him in this place other than those who took people's soul. The thought of being poked by those bony fingers of one death god made him shudder, he considered opening his eyes ( which were still closed from the beginning) to look, but decided against it, not wanting to lose any last bit of his sanity as he had seen enough crazy things already (living in the mafia and all). So he kept his eyes shut and tried his best to ignore the poking, which was becoming more difficult with his growing annoyance.

"This should be worth it" he grumbled before slowly opened his eyes only to be blinded by the sunlight, blinking a few times to adjust with the sudden brightness, he sat up, noticing a good amount of seagulls on his body before they scattered away, and looked around. He was indeed on a small boat, but instead of the river of hell, the boat was floating freely on the open sea.

"So that's why hell has a salty scent in the air" he muttered to himself, realizing how dumb he was for coming up with the hell-river thing in the first place. He sighed, feeling the last precious bit of sanity dripping away at the thought of his miraculous coming back to life and somehow stuck in the middle of the sea. If people often call these kind of thing smell fishy, i would think of it to smell like espresso and marshmallow' This, however, was proved to be the least he could worry about when he felt something sticky on the shirt he was wearing. It was blood, he realized. He didn't feel any pain though, nor could he find any injury, then it would means this was someone else's blood.

Bringing up his hand to exam the blood, his eyes widened when he saw his hands looked considerably smaller and smoother than before, he was 41 for god da*'s sake, his hands couldn't be this small. Then something clicked in his mind as he started examing his body as well. It seemed that his body was reverted back to its youth, about 15 or 16 if the small frame and the lack of scars were anything to go by 'The thought of marshmallow maybe right after all' .Holding back a curse, he scanned around in hope of catching sight of nearby land. Finding none, he slumbled back tiredly down the boat. All the thought about how he got here and the abnormal reverse of his body could wait, the most important thing right now was to find a way back land safely. A loud growl interrupted his train of thought.

"Urgh, so hungry, if only a big fish could emerge from the water for me right now, i'm too tired to catch one." He whined, then snickered to himself, knowing his luck (which was worse than mukuro's laugh itself), that would be unlikely to happen.

As if on cue, something big, no, giant emerged from the water, making the small boat sway uncontrolably, almost capsized. The figure revealed to be a ridiculously giant fish which had a face of a cow, baring sharp teeth and staring at him like a predator staring at its prey. The boy on the boat could only gape at the looming figure with a 'WTF' clearly written on his face.

"Well, Karma is always a bitch" he grumbled. Somehow he wasn't too surprised about the change of event, leading to the question whether his sanity finally disappeared completely, or maybe it had ever since Reborn arrived at his doorstep, he didn't know. Leaving that thought aside, he was intent on not becoming this creature's breakfast, or lunch. He clenched his fist and closed his eyes, preparing to enter Hyper Dying Will mode, which he had learned to enter without the pills, to beat the crap out of the da* fish and perhaps, make himself a nice meal of fried sea cow (he refused to call it a fish). Feeling nothing like the familiar power, he tried to concentrate again, but to no avail. "I can't even use the Dying Will flame now?!! What's wrong with my luck?!! Did i commit some kind of high treason against gods in my previous life?!!" He called out in frustration, having a sudden urge to punch someone, or something, a half cow half fish hybrid to be precise. He glared at the predator-now-likely-to-turn prey, an evil smirk on his face which made the sea cow sweat slightly. "I don't need my flame" he mumbled to himself "one punch is enough to send this guy flying" with that he advanced closer to the creature. A distant shout from behind made him stop however..

"GOMU GOMU NO..." before he could even comprehend what was happening, a hand? blurred past him "...PISTOL!!" and headed straight into the sea cow's body, sending it flying back a good distance before falling down the sea. The stretched hand How was it even possible?!!' snapped back to where it came from behind him. He turned his head to see a grinning teenager with obsidian eyes and a small scar under his left one. He was wearing a red vest, blue short with a straw hat on his messy black hair, he assumed this boy was the owner of the weird stretching hand. Beside the teen was another teen with blond hair brushed over the left side of his face, revealing distinctive eyebrow with a spiral at the outer end. He is wearing a black, double-breasted suit with a tie and along-sleeved, buttoned shirt with stripes. He had a slight scowl on his face with a cigarette hang on his lips.

"Oi!! Are you ok there?" The straw hat teen shouted, the wide grin still on his face.

"A-ah, i'm ok" he stuttered, shock still presented on his face (and to think nothing could surprise him anymore after 27 years living with Reborn and his guardians) "Thanks for saving me" shoving all the questions at the back of his head, he managed a small smile.

"Shishishi, no problem" the two teen's slightly bigger boat sailed toward him. Gainning a good distance beside his boat, the straw hat teen beamed "I'm Monkey.D.Luffy, the man who will become the Pirate King!!shishishi"

"The Pirate King?" He asked dumbly 'was he sent back to acient time or something??'

"Yep! I will become the Pirate King, who have the most freedom in the world!!" The boy now known as Luffy added confidently, hands throwing in the air. The blond man beside him smiled slightly, then stuck a hand out from his pant pocket

"I'm Sanji, you are?" He took the hand and politely introduced

"Just call me Tsuna" he intentionally left out his full name though in favour of following his intuition. Sanji nodded in acknowledgement then turned to the straw hat boy "we'd better hurry up Luffy, i don't want to let our Nami-swan wait any longer!" The blond man seemed to swoon over the name, which was quite a bizarre sight considering his previous attitude. Luffy nodded before waving at Tsuna " We have to go right now, see ya!"

"Wait!" The brunet called out making the two tilted their heads back to look at him "Can i travel with you guys to the nearby land, you see i can't navigate so i'm stuck here" he scratched the back of his head sheepishly. A grin again spreaded on the straw hat boy's face

"Sure!"
