Disclaimer: Neither Potter nor Moon world is owned by me in any form, except my copy of bought books/manga/videos of the respective series. If either creator stumbles upon my humble little fic, I mean no harm, and it was purely for the benefit and entertainment of my creativity and to supply a continuation of the popularity of these series to the rest of the world. May the good never die and the bad burn away and disappear far from sight forever.

AN: This is why I should never be lead to areas of Fanfiction that I hadn't intended to go. First it was twilight, then it was Sailor Moon/Twilight- still haven't looked too closely there, but started writing for it, erg. Now I've been drawn into the Sailor Moon/Potter world, something I've kicked around with in the back of my head before, trying to make it sound good and not a cheap attempt to throw them together. I had a really great idea once, and it sounded really good, but I didn't write it down, and it stuck in the back of my head taunting me just out of reach of what it was years later. I tried writing a Potter fic after the 3rd one, and it was very similar to the 4th book before it came out, just reversal of who was mad at him and location- I thought he'd end up in the desert with Wormtail and Voldemort and one of his friends would help him back. Wasn't quite like that, and after reading the 4th book I couldn't continue. Now... a couple of stories have pulled me in, either because they're using a lot of my ideas when I leave reviews for them, or stories that make me angry with how poorly thought out they are. So... I'm writing this fic to rectify it. It won't be long, I hope, it's not my intention to start a new story, but it must be done, because frankly, this new idea won't leave me alone.

An2: Now, before you get on me about this taking place in England for the Senshi world, let me remind you, they're not supposed to be in America either, the story took place in Japan, brought to the ENTIRE world, and given names and languages to fit the region that they came to. Serena was supposed to be named Victoria at first (which is funny with the whole twilight thing... never mind), and in the manga calls her Bunny. Point 2: There are at least 3 other Wizarding Schools that are mentioned in the books and they're only in Europe. If Serena/Bunny/Victoria/Usagi/Odango/Etc. had been in any other location but London, including Japan, she wouldn't have gone to Hogwarts, no matter how you finagle it if she were a Wizard/Witch from any other location, she would have gone to the closest one. Who's to say there isn't one in Japan?

AN3: I'm writing this is FOUR years, not SEVEN and so they're FOURTEEN when they start. When I started this story I hadn't read the books for years (except for the 3rd one) and I've seen the movies off and on at different times and not always in order. I'm going to go back through all the books soon. I should note that if you've read this story before 3.5.2017, I've gone through and edited a lot of it but I might go back through and do it again. However most of the 'inconsistencies' some of you might think are in this story are INTENTIONAL and some if you've only seen the movies are true to the books and some things are true to the movies and not the books. It crosses between both worlds and some things have to change to fit this new combined world.

Please Read and Review and Enjoy!

Year 1

Chapter 1

–

The night was silent on Privet Drive, all except house number 9. The commotion that went on was ridiculous, or so thought the Dursley family, not more than five houses away from them, in their own residency, in number 4. It was August and Vernon was not a happy man, inside the cubby-hole they used to stuff the Potter brat, now resided the one thing he and Petunia had sworn would never happen to the boy: be invited and accepted into Hogwarts, School for Witchcraft and Wizardry, and proof of it was sitting in that cramped space; the trunk he would use to leave the house and head off to school. Despite all of their efforts, Harry was informed and told so directly on the day of his birthday. The letters had started long before that, and built up when they hadn't been received by the intended addressee.

If they didn't cause a hubbub with all of their commotion, he didn't think it appropriate for this family to begin now, and it was quite a racket as their houses were on the furthest ends of the neighborhood. It was also the middle of the night and Vernon threw his robe on to go deal with the problem, Petunia didn't even stir from the bed, except to tell him good luck.

Harry stood at his window and watched his uncle clad in blue robe, striped blue and white pajamas and blue fuzzy slippers stalk down the street to the house that their newest neighbors had just moved into. He was curious; he had been hearing noises from the street so much clearer now that he actually had a room, the room Dudley had used as his closet before life had changed for Harry. It had started before his birthday, he just hadn't realized it until Hagrid forced his way into his life, on his birthday, and the half-giant was a better present than any package he could receive.

Harry had seen the moving trucks shortly before Dudley's birthday, and had seen the woman, a tall leggy woman with black hair that came down her back with the strangest sheen of green in it. He had thought it had just been a reflection of light off one of the packages around them, but he couldn't shake the feeling that it had been that color for real. She had turned her garnet eyes onto him and shooed his eyes away, to go back to what he was doing.

He complied, but out of the corner of his eye, he'd seen the man unloading the truck, he was tall, thin and had short cropped blond hair. His clothes were loose and baggy, not the typical style for Englanders and she spoke with a crisp London accent; he hadn't heard the man speak.

He hadn't seen any children, and so he went back to the weeding of the garden Petunia had ordered him to do. She didn't mind planting, but maintenance wasn't her strong point. He'd ripped at the weeds, tearing them out of the ground with frustration, he hated the chores, and he hated that none of the children his age would speak to him, all too scared of Dudley's influence. He'd hoped to meet these newcomers and intervene before Dudley had poisoned their minds, but it seemed, there weren't any children at all, just another barren house on the block to go with all the others. Dudley and he were the only children in the neighborhood; all of Dudley's friends came from the adjacent one.

This was before he'd realized that he would be going to a school far away from here, somewhere he'd never heard of before and Dudley would be going to some crummy private school here in London that his dad wanted him to go to. A happy smile returned to his face with that thought, and Harry continued watching his Uncle's heavy footed progress towards the neighbors. He could move when he wanted to, but most of the time he was just as lazy and fat as his son.

Harry hated to admit it, but he took after his aunt, with the long skinny body and dark hair, but he was different too, he was still short for his age and his skinniness might be out of malnutrition rather than genetic traits. His aunt had darker brown-reddish hair and his was almost completely black with the exception of a few red-colored strands that he'd see when it got too long and shaggy. His eyes were green while her's were a plain, boring old color and his skin was several shades darker than the Dursley family's.

The door opened along the long narrow street and the man stood, propped up against the frame with his arms crossed against his chest. Even from this distance, Harry could see his uncle turning red, but either from embarrassment or anger, he wasn't sure. He leaned further into the open window, resting his arms against the top of the sliding glass, the top had been taken down for air and he hoped to strain his ears far enough to hear the conversation.

The noise had ceased and the two men talked for a little while before the other man turned and shut the door in Vernon's face. Harry's uncle turned back towards their house, stomping in anger, he had not gotten what he'd wanted and Harry knew that tomorrow would be a rough day on him.

His summary of the following day was exactly like he'd thought it would be, he got yelled at, told to do more chores, added to his already towering list that he needed to complete before he went off to Hogwarts and he'd been denied breakfast and dinner, only sneaking lunch in when Petunia wasn't looking. Dudley wasn't making matters any better; he would spill things and claim it was an accident, adding only more to Harry's list. His only reprieve was when he and Petunia left to get "Dudley-woggums" some new clothing for the school he'd be attending. It didn't last long as Vernon returned home and shouted orders at the poor boy.

"Dudders" got a lot of praise when he and his mother returned and Harry was loaded up with bags and told to put the overgrown boy's clothes away. Harry was sorely tempted to toss them in the closet and say that's where the pig usually hoarded his stuff, but he knew better and he only had a week to trudge through before he'd find himself in a boarding school that offered him only freedom from the life he had been in for the last 13 years. The only other time he'd known it, he'd been too young to remember or take advantage of.

Later that night, Harry escaped to his bedroom before more work could be tossed at him and sat in his chair by the window and looked out at the house that had been quiet all day and all night since the interaction the night before. A room was lit up in the upper floor, the window was small, but he could catch a shape moving within, it looked like it was dancing with the way the shadow flickered. He fell asleep watching the movement, something in him, comforted by that sight.

The week went by slowly; it wasn't fast enough for Harry in his excitement to get to the new school. He'd found himself catching a bus the morning of to the train station, his trunk filled and Hedwig in her cage. The bus driver had barely spared him a glance or the bird, and Harry thought that odd as the rest of the passengers kept looking at it. He disembarked the bus and pulled his trunk along, looking for platform 9¾, but it was nowhere to be found, he'd gotten waved off as if he was just some prankster when he'd asked the train station attendant and now found himself staring at a wall between platform 9 and 10. The red-haired family had been kind enough to explain it to him when he'd stumbled upon them and watched as one by one, as the red-haired children disappeared into the very same wall.

He looked back towards the little red-headed girl, wondering why she wasn't joining them. "She's not old enough yet, she'll be along next year. Go on ahead; it's Ron's first time too."

Harry took a deep breath and with Ron, they ran towards the wall, hoping not to be flattened against it or make fools of themselves by bouncing off. They made it through just as the train began to whistle. "Well, come along, me brothers should be up ahead of us. I'm a first year too; would you like to share a cabin?"

Harry and Ron made it onboard and stationed out in a cabin before anyone could claim it. It wasn't long before the train took off and a girl with frizzy brown hair was forcing her way in, her front teeth slightly too large for her face. She was already dressed in her black robes for the school. She'd introduced herself as Hermione and ignored Ron's rude behavior and fixed Harry's glasses for him. They both learned his name and who he was, Ron seemed impressed, but neither made a fuss and accepted him for just being some kid who'd become famous and then disappeared for years. Ron was more interested in the cart coming by with all the candy on it.

"Be careful of the frogs, or they'll-" Harry found out the hard way as it jumped onto first his head, then out the open window.

"Well, if it isn't a mudblood, a Weasley and Potter."

"You take that back!" Hermione snapped, standing and had wand out, pointing in the face of the too-blond haired boy with his two goons beside him.

"Oh relax; I have no interest in you." The boy turned his attention to the two sitting still. "What's the matter Weasley, you haven't gotten your hand-me-downs yet?"

"I've got my robes, and that's all." Ron was sitting forward, ready to attack if provoked.

"I don't see why you'd degrade yourself like this Potter. One's got no magic in her family, and the other is an embarrassment to the wizarding community."

"I've made my decisions Malfoy; you might as well move on, this cabin is full."

The boy, Draco Malfoy, made a face and turned around; he wouldn't associate with Potter longer than he had to, if that's his response.

"I think you've just made yourself an enemy." Ron stated once the door slid shut again.

"What's a mudblood?" Harry turned to look at Hermione, who was still fuming over the name.

"It's a slang term, very bad actually, for a witch or wizard whose parents are not magical. There's half bloods too, who have only one magical parent, the other a muggle." Ron explained, so Hermione wouldn't have to go into the explanation herself. "It's almost a swear word the way some people use it, it's shortened from the real term: muggle-born."

Harry frowned, clearly disgusted with the term himself and offered the two some of the candy he'd bought, actually for them. "My parents are very proud of me, couldn't be happier when I got my letter from Hogwarts, we had to figure out what it was first, but once we did, it was ok by them." Hermione finally spoke, digging into a Bertie's bot.

The sorting hat placed Hermione, Ron and a few other kids that Harry had gotten to know in the Gryffindor house, Ron sat with his brothers, second to last child in the family, and following in all of his older brother's footsteps. The poor girl, he mused as he waited his turn, being the last child, and only daughter with six older brothers, it must have been hard on her in numerous sort of ways. Malfoy and many of his followers and his like were placed in Slytherin. Harry knew one thing; he didn't want to be in that house.

When his name was finally called, there was a hush that went through the room and he made his way to the sorting hat with all the eyes on him, it was very nerve racking. He sat on the chair and the hat was plunked on top of his head. It felt like forever compared to the others, and the hat spoke to him while he chanted over and over again "please, please, please Gryffindor."

"Gryffindor, hmm? I see great things for you in all the houses, but no, you do not belong in Ravenclaw or Hufflepuff, you are right, but Slytherin calls to you too. Are you sure you don't want to be in that house? Many great, terrible yes, but great things have come from there. Many great people, very powerful indeed. Well... if you're sure-" Out loud to the entire room, the hat bellowed. "Gryffindor!" The table that sat the Gryffindor house erupted into applause, as they hooted and hollered as the hat was taken off of Harry's head and he made his way to his new friends.

The surnames flew by from P to R before another name was called out. "Serena Riddle!" The silence that followed was deafening, and the treatment the blond girl received as she walked up to the stool was frighteningly frosty, except for a few exceptions at the Slytherin table, they began whispering amongst themselves, and then the whole room erupted with chatter.

"Who is she?" Harry leaned forward to talk to Ron and Hermione. He was imagining she was some celebrity's daughter in the wizarding world, or a controversial muggle who appeared to have wizard powers.

"That is..." Ron couldn't finish.

"He-who-must-not-be-named's child." This Serena practically glided up to the stool and perched there as if she were a princess.

"No, you have to be wrong; she's too... bright to be the dark lord's child." Ron disagreed.

Harry had to agree with him, he didn't know this 'dark lord' they were talking about, but the girl seemed like royalty and held herself that way too, but didn't look presumptuous, just... regal. "What are you talking about?" Hermione whispered furiously back. "She's totally got that well-endowed; everything belongs at her feet attitude."

"Oh, calm down Hermione, she's just got good posture and is pretty." Harry tried to get the brunette to sit back and wait out the results with him. If anything, her sorting took longer than his had, and his had felt like forever and a day. For other children, it had been barely touching their heads, or even in the motion of going downward when the hat had called out their houses, what was it between him and this girl that would require something different? Would she be placed in the two he didn't belong in, and the hat was trying to sort that out, or was she the same unique issue that Harry had gone through? Between Gryffindor and Slytherin? He hoped she didn't get put in Slytherin, she looked completely out of place with those oil-slicked heads at the table next to them, and they seemed to be relishing her arrival in their house with great anticipated breaths.

"Harry." Hermione was saying, trying to get his attention, and seemed to be frustrated at her efforts too, he wondered how long she'd been saying his name. "Do you not know who the dark lord is?" She asked when his eyes came to her.

"He's the one that murdered your parents, tried to do so to you, and gave you that scar." She whispered so only he could hear, but everyone else, but him, had already heard the story a hundred times. She just didn't want to point it out, lest they didn't know; he was actually the Harry Potter.

"And she's his daughter." Ron finished. "We didn't even know he had a daughter."

"So then maybe she isn't?" Harry asked hopefully, but somehow already knowing the truth as he looked forward again at the girl still yet to be sorted.

Ron's response clinched it. "There are no other Riddles in the Wizarding world."

"Gryffindor!" The hat declared just as Ron's words came to a halt, startled everyone, and there was a ruckus at the Slytherin table as the Gryffindors put up at least a little show of welcoming their newest celebrity wizard child to their table, the clapping was intermittent and weak. Serena didn't seem to mind as she floated towards them, before tripping on an invisible crack in the floor and went flying forward before catching herself and sliding with a red tint to her cheeks into an available spot. Two more opened on either side of her as she sat down and people squeezed close to their neighbors so as not to be near her.

Harry would have gone to her side but Professor McGonagall was at the foot of the Slytherin table, ready to chew them out, but a man in black robes, with black hair was at her side before she spoke. "Minerva, if you'd please allow me to handle my own house." His voice was very dry and his black eyes looked slow but there was intelligence behind them as he looked at Harry and then at Serena, and more than that, there was malice, at least towards him.

McGonagall nodded and left to go back to sorting. "Please do, Severus. Kayla Ritchee!"

"10 points from Slytherin, this is a very poor start to the year, ladies and gentlemen, I expected better out of you, we're not Gryffindor, now are we? We do things with taste. You first years have a lot to learn, and I had thought the other years would be able to teach it to you. Now settle down."

"But Professor Snape- Serena- the hat got it wrong!"

"The hat does not get it wrong; now sit down Mr. Malfoy, before you force me to take more points away."

Malfoy sank back to his seat, but he was ogling Serena, who had her back to him and was completely unaware of the discomfort she had around her, or at least pretending very well that it didn't bother her. Harry didn't like the Slytherin ogling one of the people at the Gryffindor table, even if she was perceived as the dark lord's child, he was sure there had to be some mistake, she didn't look evil. She could have been a muggle-born with the unfortunate side-effect of having the same last name as the evilest man in all of the wizarding community.

Harry stood and Snape's black eyes turned to him as he was just heading back to the teacher's table. "What do you think you're doing Potter?"

"Exchanging seats?" He responded with his own question, as if it wasn't allowed.

"Proceed." Snape watched, the whole room watched, as Potter moved down the rows to sit next to Serena, almost close enough to be touching. Snape's eyes narrowed at this, but he turned back to the table that all the Professors sat at, save McGonagall. The headmaster's eyes danced at the move, and McGonagall seemed pleased as well.

Serena's gaze turned to him and she offered him a small smile in thanks before her eyes went back to the table. Her energy seemed to brim with good feelings, so he didn't understand what everyone was so afraid of. She hadn't killed his parents, even if her father was the 'dark lord', just as he hadn't killed the dark lord, it was his mother that had sacrificed herself to save him and she ended the other man's life.

When sorting was finished and all houses assigned, the headmaster gave his speech for the new year "blah, blah blah... Hope we all make unexpected friendships that last us a lifetime... blah, blah, blah..." Then the feast was before them in a wave of his arms.

"Wow." Serena looked at all the sudden food. "I think I've gone to heaven."

"Me too!" Harry and Serena dug into the food, bringing it all onto their plates as much as they could and while Harry dug into it with relish, never seeing so much food he could eat, Serena was scarfing it down quickly too. He caught himself chuckling as he watched her; it seemed she had it down to an art, getting as much food in without choking or getting fat. "Wow, I've never seen someone so skinny, eat so much."

"Ah..." She rubbed the back of her neck. "It's kind of a trait of mine, sorry. I'm sure it looks disgusting, how much food goes into my body." She followed it with a laugh of embarrassment.

"No, it's fine. I think you should enjoy your food." Just not over-do it like Dudley, though he didn't know how much food this girl was used to eating, she must not have more than 3 meals a day if she ate like that. Dudley never stopped stuffing his face throughout the day, it was disgusting.

They continued to eat in mostly silence. Every once in awhile, they'd begin some line of commentary before it was time for them to follow their Prefects to their house quarters and learn the password to get past the Fat Lady.

Harry had lost Serena in the shuffle, but Ron and Hermione had teamed up and were at his elbows as soon as they started walking. "What was she like?" Ron asked excited and Hermione slapped him across the back of his head. "What was that for?"

"She's evil's spawn!" She hissed.

"She's also cute." Ron responded and Harry settled into the feel of this, they'd only known each other a day, but already he felt like they'd been friends forever.

"She was... nice. A little quiet, but really, no alarm. Maybe you're wrong guys, maybe she's not Voldemort's child, and maybe she's just a muggle-born and has the last name Riddle."

Ron seemed to think about this but Hermione shook her head. "That'd be a big coincidence. It's not common knowledge, in fact, I think there was an attempt at a cover up, but with the way the Slytherins were acting, I have to suspect that she is Tom Riddle's daughter."

"But she's in our house!" Ron protested he didn't want the worst wizard in history's offspring anywhere near his quarters.

"Maybe it's a mix-up." Hermione put out there.

Harry and Ron both shook their heads. "No, it took forever, but the sorting hat is never wrong." Ron was sure about this. "She's here for a reason, if you are right and she is the heir, but I feel as if it's a good sign if the hat put her here, it has to attest to her character, right?"

"Only time will tell." Hermione finally responded, she cast a suspicious eye towards the blond, walking by herself a little ways back, a couple of other girls were looking at her, as if trying to decide something before one finally braved it and started walking with her. The two chatted and more slowly joined them, but not many.

Harry had a feeling that something bad was going to happen and he rubbed at his scar. He saw the new defense of dark arts teacher walking away from them. "Time." He agreed, and nothing else but her behavior would change his mind that she wasn't actually evil reincarnated; Hermione would soon learn that, he was sure. In the meantime, he was going to go up to his room and unpack what little he could and get ready for the day's events ahead of him.
