Chapter One: The Job

Ryu Hisanaga sighed as he collapsed onto his couch looking glumly up at the ceiling. At 19 he was seven feet even with an odd pair of eyes, the right was dark green while the left was bright gold with a trio of scars descending down across it. His dark brown hair was cut close to his head in a militaristic style with a scrawling tattoo across his entire body. He was currently wearing a pair of black jeans with a woodland cameo t-shirt.

'It's been three years,' He thought as he looked around his room with hooded eyes 'Three years since I came to this dimension...'

Yup, Ryu Hisanaga would be technically classified as an dimensional alien, see it all started back in his his dimension, the Elemental Countries.

Flashback

Ryu watched in awe as he witnessed the long awaited fight between Naruto Uzumaki, the Kyuubi Jinchuriki, and Tobi, the mastermind behind everything, from the Kyuubi attack, to this war. He was apart of the unit sent to support Naruto to battle the resurrected Jinchuriki that Tobi was using as his Rinnegan paths. He was sent with his senior Jonins Might Guy and Kakashi Hatake due to his mastery of Fuuinjutsu, which despite his age, was coming close to Jiraiya's and the Yondaime's level in the art.

It had been a harrowing battle, especially when Naruto was consumed by the Yonbi, and Ryu was sitting close to empty having fought the battle using his signature Raiton jutsu the Kinraiton: Rakurai Kyoshin(1) a technique only possible by channeling his lightning infused chakra along his nervous system granting him a zero-point reaction time with enhanced speeds easily able to match Guy when he had released his gates.

As Ryu watched he couldn't help but to be continually impressed by the Kage-level Genin who should have been promoted long ago in his mind. While he had never dealt with the genin himself he knew about him, he had watched his battle with Neji and heard the tales from Kakashi at the bar of his adventures and misadventures during his various missions. While the kid was not as smart as he could be, he showed a certain kind of ingenuity often creating a plan by flying on the seat of his pants and pulling off difficult to do tasks.

As fight progressed Ryu could see the exhaustion setting in on the two shinobi when he saw it. The space around Naruto was beginning to distort, Tobi was activating Kamui. Forming the ram seal Ryu gathered his remaining chakra as Kakashi and Guy tried to making it in time, activating Rakurai Kyoshin Ryu blurred forward putting everything he had into the dash and reached Naruto pushing him away from the Dimensional technique.

Naruto looked up in horror at the jonin who only looked a year older than him as he was pulled into the technique. The grin on the man's face was unmistakable "Kid, don't let this go to waste, become the goddamn Hokage!" He shouted at Naruto his mismatched eyes glinting as he vanished.

End Flashback

When Ryu woke up he discovered himself in a forest on a completely foreign world. It had taken him nearly an hour to reach the outskirts of a small town where he quickly used a henge to blend in with the crowd to gather information.

A surreal experience to be sure, and only his years of Shinobi training prevented him from fucking up, so to speak. After locating a small town he managed to find a bookstore – something he found to be invaluable when learning a new language – and quietly stole a few of what he assumed where beginner books thankful of the various seals located on his body allowing him to store the books within them making it easier to prevent being caught. After setting up a camp outside of the town laying down several genjutsus to be on the safe side, he began reading the books trying to learn the language.

After a full week of reading the books and deciphering the meaning behind the words before heading back into the town under a layered genjutsu to hide himself from people so that he could listen in on their conversations picking up even more of the language, and most importantly, gathered information about the world he was currently in. It had taken him a week to gather enough information, from conversations, books and newspapers, and finally understood enough to start integrating himself.

The first thing he did after leaving the small town (He never did get the name of it) was locate the criminal underground. Despite his own personal hatred of bandits and criminals, he knew that in terms of getting what you needed you need not look further than the Black Market. And with him being a alien, both literally and figuratively, he needed to access this market to get a forged identity going.

The first problem he faced, however, was the fact he had no money. So he used the basic skill that all shinobi learn, assassination.

After doing a few hits for the mob in exchange for the needed documents and some cash he settled himself down and opened a private investigations shop.

It was about a year after he opened his shop – The Dragon's Eye – that he found out about the second world hidden withing this one. A housewife had hired him to investigate her husband who she assumed was cheating on him (He had received so many of this requests and half the time they were proven false). So he followed the man over the course of his day when it happened, the man completely disappeared from his senses, no warning, no nothing. He was just gone.

It baffled Ryu that an untrained civilian could do this so he he kept an even closer eye on his when the man finally appeared again and actually saw him vanish with a loud bang. The next day he was following the man he purposely bumped into the man by pretending to be in a rush placing a hidden tracking seal within the man's clothing. The next time the man disappeared Ryu was able to follow him utilizing shunshin no jutsu.

It was then he found the hidden world of wizards and witches. The hidden world of magic. After following the man and completing his job – the man wasn't cheating, just an extremely dedicated worker – he learned more about his hidden world slowly integrating himself with it.

It was a much harder task then integrating with the normal – although the wizards called it the Muggle world of all things – world due to the necessity of magic, but with some carefully used ninjutsu and genjutsu he managed to pass himself off as one. Apparently this world was in the middle of some sort of civil war with the 'Pureblood' faction – people who felt that inbreeding was the best way to do things and to force out any half or mudbloods – People with non-magical ancestry – against the people who were for equal rights.

He had quietly involved himself with the equal rights supporters taking on the bounties of the so called 'Death Eaters' killing dozens of them over the next year earning a name for his hidden face – the Death Reaper – something he was rather proud of, although he found it was rather stale, and only his magical go-between knew that he was the Death Reaper.

The was had just ended that day thankfully, but for him though, it came at too high of a cost, not only was a child orphaned as a result of the mothers sacrifice – one that was not honored in no way what so ever – but many of the 'Pureblood' faction got off scot free bribing the ministry and claiming they were being controlled.

'Three years since I have entered this dimension, and I am already pissed with the government...' He let out a harsh chuckle at that thought 'But people always complain about the government... don't they?'

Letting out a final chuckle he booted up his computer to check for any bounties he might be interested in.

London Streets

Minerva McGonagall sighed as she walked through the muggle streets of London with a disillusion charm around he to avoid speaking with anyone. She was feeling rather guilty with herself for allowing Dumbledore to have his way and placing the girl-who-lived, Jade Lillian Potter, with those despicable muggle relatives of her mother, Lily Potter nee Evans. She had nothing against Muggles in general, but she could tell that these were the worst type of them. Just like there were bad wizards and witches, there were bad Muggles.

'I just hope that I am wrong about them,' She thought to herself as she entered the Leaky Cauldron that was full of patrons celebrating the fall of Voldemort. Sitting down in a private booth she ordered a bottle of fire whiskey and told the bar owner, Tom, to forget the glass as she drank straight from the bottle belching out a stream of flames after she downed a couple of mouthfuls in a single go.

"Wow Prof. M. that was impressive," A roguish voice commented impressed as a person slide in across from her, he was on the short side standing a 5'5" and built like a whip with narrow brown eyes and a thin nose and a mop of raggedly cut black hair "To bad you didn't teach that in class, I woulda paid more attention then."

"Mr. Axely," Minerva said with a slight smile to one of her former students "Perhaps if you actually applied your talent of transfiguration to your schoolwork instead of trying to, and I quote, 'Build an army to first conquer the school, then the world' then perhaps you would have been ruler of the world."

Mike Axely laughed loudly as he slapped his knee "I knew I liked you for a reason Prof. M." He said cheerily before straightening himself "So what's got you in a sour mood, is it the Potters, knew you was fond of them."

Minerva sighed as he slumped slightly taking another swig of fire whiskey "Partly Mike, partly," She admitted, the one thing she knew about Mike Axely was that despite his, shall we say, less than reputable business in information, he would never speak to anyone with anything she told him, she had no clue why, but she appreciated it none the less "It's what we're doing with their daughter, she's getting sent to Lily's muggle sister..."

Mike frowned as he lent back in thought, his dexterous hands twitching "I remember hearing Lils talk about her," He replied his forehead creasing "Started off well enough, but once they found out bout magic things went sour and her sister declared an absolute hatred of all things magic and related to Lils, not a good idea to send her daughter there."

"I know, Mike, I know," Minerva sobbed "I warned Dumbledore, but does he listen, no, just assures me that this is for the 'Greater Good'!"

Mike nodded knowingly "Yeah, but he never shares his plans does he?" He growled bitterly "And he wonders why I left the order of the fried chicken."

Minerva snorted at Mike's nickname for Albus' Order of the Phoenix "That was a big loss for us Mike," She said sadly "I'm worried about little Jade, I don't think they'll care for her properly, but... with the magical system the way it is..."

"You won't be able to do anything," Mike finished his forehead creased in thought before blinking and snapping his fingers "Then we work outside of it," He said suddenly getting a confused look from his old professor "I have a friend, he's not magical per say, but he does have some good skills backing him up, have you heard of the Death Reaper?"

Minerva blinked in surprise "You mean the guy who cashed in all those bounties on Death Eaters?" She asked "I only heard some rumors from Mundungus, not that I put any stock into them."

Mike nodded in understanding "Well, I act as the guy's go between in the Magical world, he's a bit paranoid, but the best, kinda like Moody, but not as ugly," He explained "See, he runs a Private Investigations shop mostly to make ends meet between some of his more... unique jobs. I won't lie some of the work he does is less than legal, but I'll be dammed if that man hurts an innocent, woman or child."

Minerva nodded slowly processing the information "So what about him, I assume you have an idea?" She asked.

Mike grinned in a savage way "The way I see it, if you or I were to take the young orphans into our care, Mister Twinkly Eyes will find out too quickly," He began his hands splayed out on the table showing his seriousness "But my friend, not even I know where he lives, just the location of his shop, and he'd be able to protect the girl if any trouble pops up, quite well in fact."

"But that raises a problem though," Minerva stated worriedly "He's a killer... wouldn't that be worse in a way?"

Mike sighed "I understand your worry Prof. M. but why don't you meet the guy first," He said pulling a card out of his robes that had an address on it "He'll be working late tonight, if you go tell him Mike's calling in his favor, been good seeing ya Prof."

Minerva nodded absently as Mike slipped out of the booth and melted into the crowd as she stared at the innocent looking card. Letting out a sigh she polished off the bottle showing remarkable tolerance to alcohol by not showing the least amount of intoxication and left the bar leaving a single galleon for the drink.

The Dragon's Eye

Ryu sighed as he absently flipped through the 'London Times' as they talked about a local terrorist being taken down knowing they were speaking about Voldemort, why people were so scared of speaking his name he'll never know, when a knock of the door interrupted his musings "We're open!" He called out wondering who it would be at this late hour as a middle aged looking woman wearing a sharp looking business suit with a knee length skirt and her hair pulled into a severe bun "Welcome to the Dragon's Eye ma'am, I an the owner and investigator Ryu Hisanaga, how may I help you?"

The woman looked around the office for a minute taking everything from the couch Ryu was sitting on to the door to the bathroom before nodded slightly, if in approval or something else he couldn't guess, before taking a seat in the chair across from him "My name is Minerva McGonagall," She stated with a nod in greeting "I come to you in a... curious position Mr. Hisanaga, I am the current Deputy Headmistress and Transfiguration Professor of Hogwarts School for Witchcraft and Wizardry," Ryu's raised eyebrow showed the slightest hint of surprise at her statement "And I am currently troubled by something, I assume that you know of how the war with Voldemort ended correct?" At Ryu's nod she continued "Well with Jade Potter, the Girl-Who-Lived, now an orphan Albus Dumbledore, the current Headmaster to Hogwarts, decided to place her with her mother's muggle relatives.

"While I would normally have no problem with this, her Aunt and Uncle, however, are the worst example of Muggles I have ever seen," Minerva sighed heavily "I am afraid for the girl Mr. Hisanaga, and I wish to hire you to protect her if possible. Mike says he's calling in his favor for this matter."

Ryu sighed as he closed his mismatched eyes and thought for a minute "I'll help you," He agreed finally scratching his head "So what is it you're looking for exactly, me to take the kid in, to watch her?"

"I want you to watch her," Minerva said "I want you to be on the look out for any abuse at all, and if anything happens I want you to get her out of there and care for her yourself if possible."

Ryu nodded "Alright, I'll do it," He relented finally after a few moments of thought "But I will be raising her in my own way."

Minerva nodded "I understand," She sighed "But I beg you, please do not make her a murderer."

Ryu's eyes narrowed dangerously making Minerva gasp as she felt a heavy pressure set into the room "I would never force that onto a person madam," Ryu growled harshly "I would only teach her how to defend herself and those she cares for. I know what it is like to kill a person, I know how it changes a person too."

McGonagall nodded as she wrote down the address for the Dursley's "I sincerely hope that I am wrong about the people she is with..." She said heavily "But... I would never be able to face Lily and James if I did nothing."

Ryu nodded in understanding "So what are the specifics?" He asked pulling out a pen and pad to take down notes.

Next Day, Noontime, #4 Privet Drive

Ryu was scowling as he sat in his nondescript sedan across from number four Privet Drive observing the Dursleys as they went about their day taking photographs all the while, in particular, their treatment of on Jade Lillian Potter.

Ryu growled when he saw the fat whale of a male smack the one year old red haired, green eyed girl to quiet her cries of hunger 'Enough,' He thought to himself 'Not even a full day into the job and I'm taking action.'

Minerva had warned him about the wards surrounding Jade connecting her to the home and her blood relatives along with the ones that monitored her presence and magical output, none of them, however, monitored her well being.

Stepping out of his car he quickly put a genjutsu over the area redirecting people's attention from the house and anything that happened within it for the next hour or so. He walked up to the door and rapped on it with a henge over himself taking away his scars, tattoos, replacing his golden eye with a green one and giving him a standard business suit. Muffled cursing was heard before Vernon, the fat whale of an Uncle, opened the door "What?" He snapped angrily.

"Good evening sir," Ryu greeted with barely maintained civility "My name is Ryu Hisanaga of the Dragon's Eye Private Investigative Service, I'm here to apprehend a child in your care, one Jade Lillian Potter due to child abuse." Vernon seemed to go through several emotions at the same time making him turn an interesting shade of purple "If you do not hand the child over Mr. Dursley," Ryu continued with a sick sense of pleasure at the prune shade Vernon was turning "Then perhaps your neighbors would be interested in your business practices, or about your treatment of your niece."

Vernon paled as he shook slightly "I don't know what you're playing at buddy, but-" He began only to freeze as Ryu's expression change from his polite professional to his shinobi professional.

If glares could kill, the glare Ryu was leveling at Vernon would have wiped the man from existence completely "We can do this the easy way, where you hand the child over to me and allow me inside," Ryu explained in a cold voice "Or we can do this the hard way, I inform the proper authorities and drag your family, career and reputation through the mud, your choice."

"Fine!" Vernon snapped angrily as he stalked back into the house "Take the fucking freak! We don't want her!"

Ryu followed the man inside his entire body coiled and tense ready to strike out at any hostile threat. He entered the kitchen where Petunia gasped at the sight of Ryu just as she was about to hit Jade again who was in a ball whimpering in pain. That snapped it for Ryu as his killing intent suddenly spike from his body centering on the two adults who suddenly fainted as their son wailed "Quiet brat," Ryu snapped at the boy who instantly shut up in fear before he headed over to the young Jade Potter who was whimpering "Hush, child, you're safe now."

"Mama... Dada..." Jade whimpered out flinching slightly as Ryu placed a gentle hand on her to soothe the child.

"I'm sorry child," Ryu whispered apologetically as he gently picked the shivering child up his henge fading as he began analyzing Jade's Chakra and magical signatures "I'm sorry, but your parents are gone... they love you though, they love you very deeply..." He stepped out of the kitchen and walked over to the cupboard under the stairs, opening the door he held out a hand that glowed with chakra and pressed it against the back of the door creating a seal that held a portion of Jade's Chakra and Magical energies making it seem as if she was still there for the next ten years.

"Pa'foo?" Jade asked looking around carefully "Moo'y?"

Ryu blinked back some tears at Jade's desperate questioning "Sorry child," He whispered gently stroking her hair spotting her lightning shaped scar "I'm so sorry."

He hugged the one year old girl close to him as he left the house and headed to his sedan.

That evening, Ryu's Apartment

Ryu sighed as he entered his apartment with a slumbering Jade who had fallen asleep about an hour earlier when Ryu was doing some shopping for some necessities for the girl, he had first went to child care services and pulled in a couple of favors one of the workers owed his to adopt the girl into his own care, officially making her Jade Lillian Hisanaga, his adopted daughter.

He gently placed Jade down on his bed being careful to not wake the child before gently kissing her forehead and activated a scanning jutsu. He looked the child over ensuring her physical health when he felt it, a foreign presence withing her mind and soul. Carefully sending out probes to inspect the presence he quickly gathered that it was an anchor to another's soul having once discussed the curse seal with Kakashi and it's effects to the body, mind and soul.

His brow creased as he felt a gentle light surround the presence containing it 'Could it be her mother's sacrifice?' He wondered mentally 'I need to remove it, it's trying to entangle itself within her magical network, once it does only death will remove it...' His mouth took on a grim line as he gathered his fuuinjutsu ink and brush and took a deep, careful breath 'If I can work with the containment field, I could move it into a paper seal then destroy it, to do that, I need to link up with it and help it understand my intent...'

The markings on his hand shifted and changed to a special seal that would allow him to communicate with the protective force.

"Who are you?" A feminine voiced asked cautiously "What are you doing to my daughter?"

'So, the mother's sacrifice did cause this.' He thought to himself before answering "My name is Ryu Hisanaga, your daughter recently came into my care and I am trying to remove the foreign presence from her soul."

The protective force seemed to pause as it considered his words "What about Sirius Black and Remus Lupin, they were supposed to be granted guardianship of her!"

"Outside force have conspired to place the child with your sister-" Ryu began to explain before the force seemed to ignite in fury.

"WHAT! My sister was NEVER supposed to receive guardianship! Who placed my daughter with her?"

"Albus Dumbledore," Ryu informed licking his lips in concentration as Jade whimpered slightly "Minerva contacted me to keep an eye on Jade and remove her from your sister's home should she be in danger, I removed her earlier today, please, allow me to remove this corruption."

"But how, it's a Horcrux they can only be destroyed with certain methods that would kill my daughter!"

"I am not destroying it in your daughter, I am transferring it to something I can destroy," Ryu explained quickly "Please, let me do this, I'd rather it be done before your daughter wakes up."

The power shifted around for a minute in contemplation "What is your plan for my daughter."

"I will raise her as my own and teach her everything I know so that she can protect herself and those she cares for." Ryu informed quickly keeping an eye on the still slumbering child.

The power paused and shifted before accepting his presence "Please work quickly, I can't keep it away from her network for too much longer."

Ryu worked quickly, gently drawing the seal around Jade's lightning shaped scar before drawing an identical seal on a scroll and gently pushed his chakra into the child's system, this was the most dangerous part, if he wasn't careful, his trained chakra could end up overloading Jade's chakra coils. Another risk was him 'imprinting' his chakra signature, it wasn't majorly harmful, but it could end up changing her physically taking on some of his physical attributes.

He encircled his chakra around the Horcrux along with the help of the ancient protection spell and gently 'pulled' it into the seal imprinted on Jade's forehead causing it to glow in a sick green color before he pulsed his chakra making the seal flare before fading as the seal on the scroll began to glow signifying a successful transfer. "It worked," He told Lily's protection spell before frowning slightly "Hold on, dammit I imprinted!"

"What does that mean?"

"It means she's going to start taking after me physically, something about my Chakra, life force, imprinted itself upon her, essentially placing a part of my DNA in her's," He explained as he saw Jade shift and moan in discomfort as her features shifted slightly, her eyes became slightly more angular and her jaw bones shifted slightly taking after his a bit more "She's safe, just essentially became my daughter in genetic terms as well."

"That's good, my protection would be able to last, please, take good care of her, I can only remain as long as there is someone who cares for her, or she lives with someone of her blood, Dumbledore may have put her there hoping to double the effectiveness hoping my sister and her whale of a husband would care for her, not that they ever would."

"As I said, I will raise her as my own, I swear on it." He promised before closing the link as the seal on Jade's forehead faded away and the scar faded slightly becoming more normal looking.

Letting out a sigh he smiled as her eyes fluttered open revealing slightly darker green eyes with flecks of gold in them like his own when he was younger "Dada?" She asked in confusion looking up at him.

"I will be sweetie," He assured picking the girl up "I will be your Dada."

Jade buried herself into her adoptive father's shoulder hugging him tightly as she fell back asleep.
