I don't own Harry Potter. All credit goes to J.K Rowling but I do own my OC, Yuki.

Three years ago, Harry traveled through time with an immortal witch named Yuki.

Harry's features changed since accepting Yuki's blood adoption. He no longer must wear glasses, has emerald-sapphire eyes, a bit of high cheek bones and shoulder length hair with a bit of yellow highlights. He grew a few inches, which made Harry happy as he hated to be the shortest in his class.

Then Harry adopted young Tom Riddle who was renamed Thomas Slytherin-Fudo. He wasn't sure if he would make a great father to Tom but surprisingly, it came somewhat naturally to him.

Another surprise was the location of Slytherin manor. It was near a small town that had purebloods, halfbloods, muggleborns, muggles and squibs that live together. Not only that, but they were able to have magic and technology work together.

It was a dream come true, but Harry could see that wizards and muggles can live side by side with no hatred. So, when Tom turned five, he started preschool with all blood status of children.
While Tom was at school, Yuki continued Harry's education.

The dark hair teen thought that Snape was strict, but Yuki was brutal. Not only he was continuing his sixth-year lessons, but also politics and…dark magic?!

"Wha! You teaching me the Unforgivable curses?!" Harry said in disbelief. "There's a reason why they are called unforgivable, mother!"

Yuki narrowed her eyes, "If not used properly, Harry. Father and Aunt Ro know that there is no such thing as light or dark magic, but knowledge of survival."

"Okay, in your time, yes, but it's different now," argued Harry.

Yuki sighed, "Not true. Some wizards and witches think differently. They still think that the muggles are going to hurt them which is why so many hate them by purebloods and some halfbloods."

"Then show them!" Harry gritted his teeth, "Show them that the muggles means no harm! Like we did with the Malfoy's and the Black's a few weeks ago!"

Yes, a few weeks ago, Harry and Yuki were invited to a ministry party. It was there that Harry met the Malfoy's, the Black's, the Longbottom's and the Potter's.

Chalus Potter had dark brown hair with brown eyes. He stood proudly and behaving like a proper pureblood. However, Fleamont Potter had messy brown hair with light brown eyes. Unlike his brother, he was messing around and talking about how great he was in Quidditch.

Arcturus and Melania Black with their children, Orion and Lucretia. Both children had wavy black hair with icy blue eyes.

Pollux and Irma Black with their children, Alphard and Walburga. While Alphard had dark brown hair with blue eyes, Walburga had long wavy black hair with dark brown eyes.

Lastly were Cassiopeia Black, who had long wavy black hair with blue eyes and Dorea Black, who had long black hair with dark hazel eyes.

Then there was the Longbottom's and their son, Nicholas, who had light brown hair with light brown eyes. Lastly, the Malfoy's and their son, Abraxas, who had long blond hair with gray eyes.

After the party, Yuki invited them to come over to their manor for a cup of tea. When they came over, the families were surprised of the truth of the four founders and saw the small town that had wizards and muggles working side by side with no worry.

The Black's and the Malfoy's couldn't believe what they are seeing while the Potter's and the Longbottom's were in awe. However, this was a calmer reaction when they were told that Harry was Lord Slytherin and Yuki was the blood adopted daughter of Salazar Slytherin.

Ever since then, Harry was labeled the leader to his small group of friends.

-Slytherin Manor; Sept. 7, 1933-

"Ah Harry, how are you doing, mate?" Regulus Black smirked, "Anything good has happen? Like you know…a girlfriend?"

Harry smiled softly, "Sorry Reg, you know that I don't have time to find one."

"Regulus, you know that Lady Yuki is teaching him to be the future King of the Wizarding world," stated Melania Black.

Regulus pouted, "Aw, that's no fun! Come on Harry, play hockey for the day and I can show you the best places where you can find a fine woman. What do you say?"

Harry made a face, "No can't do Reg, but thanks for the offer."

Regulus sighed, "Fine, but let me know when you want to go. I know perfect places where you can find your mate."

"Right," murmured Harry.

Irma shook her head before smiling to Harry, "How's Hugo and Lillian doing?"

"They are doing just fine, Irma and their son, Harold," replied Harry. "In matter of fact, they are planning to move here in Slytherin manor."

"That's good," then Regulus smirked, "Any signs if Harold is a wizard or a squib?"

"A squib. Looks like their magic wouldn't return with Harold," replied Harry.

"And here I thought that Harold was just a late bloomer," Pollux made a face, "Looks like I owe you 50 galleons, Irma."

"You bet if Harold was a wizard or a squib," said Arcturus Black, shaking his head.

"It was all good fun," Pollux shrugged his shoulders before looking over to Harry, "No offense, but you really need to find a wife. You need another heir for the royal bloodline."

Harry sighed, "I know, but…you know it cannot be a mortal witch," then he smiled, "Besides, I'm in no rush to find myself a mate right now. I'm far too busy. So, what's with the visit?"

"Just want to see you're alright," Melania shook her head, "Seriously, this manor is far too big for you, your son and mother here."

"She does have a point," Pollux looked around, "This manor has over 50 rooms and you're just using ten of them."

Harry scratched his cheek, "I know that which is why I offered the Evans' to move in."

Melania frowned, "Not good enough Harrison. We thought it would be best if all of us moved here as well."

Arcturus smiled, "Well just for the summer and holidays. Can't leave Black Manor?"

"You can't, but I can," Regulus smiled, "You don't mind me moving in?"

"And you don't mind if Cassiopeia moves in as well, Harrison. She doesn't want to stay at Black Manor any longer," said Lycoris Black.

Harry smiled, "The more the merrier, that's what I say."

"Wonderful! I can't wait to tell Cassiopeia," said Regulus.

Arcturus got up, "Come on, we better get going Melania."

"Of course, see you later Harrison," said Melania before following her husband to the fireplace.

"We better leave as well," Pollux got up, "Irma and I have a meeting. See you later Harrison."

"Take care Harrison," said Irma before the two left using the fireplace as well.

"Well, I better get my things packed. See you tonight, Harry!" Regulus said before dashing to the fireplace.

Harry shook his head before grabbing his coat and was about to head out. He was going to town to pick up Tom from school.

"Zippy! I'm getting Tom from school. Mind getting supper ready?" Harry said.

The house elf appeared, "Of course, Master Harrison. Will there be others?"

"Yes, Regulus and Cassiopeia will be staying with us from now on," replied Harry.

"Right away Master Harrison!" Zippy said before disappearing.

"Rosie! " Harrison called out.

Rosie appeared in front of him, "What can I do for you?"

"Have two rooms ready in the west wing," replied Harry as he was leaving the manor.

"Right away my Lord," said Rosie, happily before disappearing.

Harry apparate to town and went over to the school. The dark-haired wizard didn't wait that long before being tackled by a young Tom.

"Daddy, you never guess what happened in class today! Come on, guess!"

Harry laughed before lifting Tom onto his shoulders, "Let's see, wasn't today that a Dragon trainer was coming to visit?"

Tom nodded, "That's right! And guess who was able to hold a baby dragon? Me!"

"You don't say? What type of dragon was it?" Harry asked.

"Um…I…I think it was a Chinese Fireball," replied Tom before scratching his head. "Or did he say it was a Norwegian dragon?"

"Well, at least those baby dragons are used to human touch," said Harry.

"Yea, Mr. Haddock said that if you ever see a wild dragon then you should either walk away or show that you don't mean no harm," replied Tom.

"Mm, different dragon means different dangers," stated Harry before stopping. "Well, hold on tight Tommy."

Tom nodded before holding onto Harry as the dark-haired wizard apparate back home.

"Yuck! I hate side apparate daddy! Next time please bring the broom," begged Tom as his face was a bit green.

Harry laughed, "Alright. Oh, also, Regulus and Cassiopeia will be moving in."

Tom grinned, "Cassie is staying with us?!"

"Yes, now homework," Harry put Tom down, "Don't rush. I'll look at it before supper."

"Yes sir!" Tom said before dashing inside the manor.

Two hours later, Regulus and Cassiopeia were moving their belongings to the west wing. Just as they were about to eat, Yuki apparated into the room.

"Oh! That is the last time I am taking a long trip – ah! Harry, Reg, Cassi and Tom; how are you all?" the immortal said.

"Grandma!" Tom shouted happily before running to her.

"I see that Harry has taken care of you," said Yuk before looking at her son. "Did Tommy behave while I was gone?"

Harry smiled, "Sure has mother. By the way, Regulus and Cassiopeia will be staying with us from now on."

"Wonderful!" Yuki said happily as she picked up her grandson before sitting at the table.

"I thought you were going to stay at Russia for a couple of more days, mother," Harry took the head seat, "What happened?"

"Oh, nothing bad," Yuki waved her free hand, "Can't a woman see her son and grandson? How are they fairing and everything?"

Harry chuckled, "So, how was your trip?"

Yuki shrugged her shoulders, "It was alright. Nothing really changed over there for the past one hundred years since the last time I was over there."

Regulus twitched his eyebrow, "One hundred years…"

Cassiopeia smiled, "I am glad you had a wonderful time, Lady Yuki. Maybe next time, I can come along."

Yuki winked, "Sure, but in the meantime, what career did you choose?"

"I'm not sure just yet," replied Cassiopeia. "For now, I was thinking if I can volunteer at the hospital here for the time being."

"Well, you are an excellent healer," said Harry. "I think…I can help you out. Let me talk to my friend, who's the Head nurse. She can help you become a volunteer or even get a job."

Cassiopeia smiled, "Oh thank you Lord Slytherin!"

Harry sighed, "You know, you can call me uncle if you like. You don't have to be so formal."

"Sorry, force of habit," said Cassiopeia. "Oh right, Lady Yuki are you planning to take back the throne anytime soon?"

The house elves started to magically place the food to everyone.

"Not yet, but soon," Yuki made a face, "The current Minister is an idiot. I have Lord Malfoy giving hints to him that the ruler of the Wizarding world has returned."

Regulus snorted, "That Minister will not take the hints unless you show your face, gran."

Yuki sighed, "Well, I guess I'll be taking back my seat once Harry finishes his studies."

"How long will that take?" Cassiopeia asked.

Yuki thought for a moment, "I believe another…three years, give or take."

"I would've finished sooner, but mother thought it would be best if I study some advance magic before taking Mastery for all subjects before Tom goes to Hogwarts," replied Harrison.

"Advance magic?" Regulus whistled, "I didn't think the Fudo's are that powerful."

Yuki winked, "The Fudo's have been living since the early 1300's and original lived in Japan before one of my ancestor's moved here in Britain around the 1500's."

"So, did your family know the four founder's?" Cassiopeia asked.

"Oh, very, but mostly Salazar and his godfather, Merlin," replied Yuki. "I was blood adopted by Salazar when my parents were killed by muggles one night."

"Muggles back then were unsure about magic," said Regulus. "I blame their beliefs about the devil and pin it on us wizards."

"At least over here, muggles are not like that," stated Cassiopeia.

"Well, changing the subject," Regulus grinned, "When are you taking your son to his first Quidditch game, Harry?"

Harry laughed while Cassiopeia and Yuki shook their heads while Tom just titled his head.

-Summer 1936, Flourish & Blotts-

"Did you find anything Tom?" Harry asked.

"Mm, not really. I would rather get some ice cream," replied Tom. "Can we go get some?"

"I don't see why not," replied Regulus.

"If you like Cassi and I can take the younger children to Florean Fortescue's," offered Yuki.

"Are you sure?" Regulus made a face, "Alphard and Orion can be a handful."

"You call those boys handful?" Yuki laughed a bit, "I've seen more handful children during in my era."

"They…couldn't be that bad?" Harry asked as he picked up Tom, placing him over his shoulders. Yuki turned around and whistled.

"Well then," Regulus cleared his throat, "I…um, those textbooks should be ready by now."

Harry leaned over to Yuki, "Mother, please behave."

Yuki winked, "I have no idea what you are talking about – ah! Over here everyone!"

"Tommy!" shouted the young boys.

Tom looked down to Harry, "Da – I mean father, can you put me down?"

Harry nodded and placed Tom down. Alphard and Orion dashed over to him and started chatting with him about Quidditch.

"Hello," greeted Walburga and Lucretia.

"Morning Lord Fudo and Madam Fudo. You as well Uncle Reg and Cassi," greeted Dorea.

Harry smiled, "Morning girls. Ready for Hogwarts?"

"You bet," said the young girls while Dorea just nodded.

Melania smiled, "Well then, did Regulus get the textbooks yet?"

"Just about Mel," replied Regulus as he returned. He patted his coat pocket before grinning, "Walburga and Lucretia's first year books and Dorea's sixth year books right here."

"Wonderful!" Irma said. "Let's get going as it's getting rather crowded in here."

"Then go to Madam Malkin's Robes as that will take a while," suggested Cassiopeia. "Madam Fudo and I will take the younger children to Florean Fortescue's."

Pollux frowned, "Are you sure? These boys can be a handful."

Regulus waved his hand, "Madam Fudo has experience of…handful children."

"If you say so," said Arcturus before nodding. "Right, Cassiopeia watch over your younger cousins while we continue shopping."

"Very well, sir," said Cassiopeia then looked at the young children, "So boys, shall we go get some ice cream?"

"Yea!"

"Have fun," said Yuki, leaving with the children and Cassiopeia.

"Well…why don't Reg and I go get the potion ingredients while you six tackle the robes," said Harry, smirking. Arcturus and Pollux paled dramatically since they would be at the robe shop for quite some time.

"W-Wait Harrison!" Pollux said.

"Don't leave us," begged Arcturus.

Harry quickly grabbed Regulus' arm and dashed out of the bookstore.

"…I'm having second thoughts of Harrison being adopted," Arcturus then made a face, "He acts just like Madam Fudo."

"Well, he did say it was an ancient blood adoption," stated Pollux.

"Right," murmured Arcturus.

The two men followed their wives and the girls to the robe store where they had to wait for their turn. It didn't take long for Dorea to be called while Lucretia and Walburga went to a room for first year students.

Dorea went to the room where there was another being fitted, Charlus Potter. She had seen him a few times in a few Ministry parties and some of her classes. Truth to be told, she fancy the oldest Potter. She had a crush on him since her third year while he was in his fourth year.

'Like he will notice me anyway,' thought Dorea, sadly. Everyone knows that no Gryffindor and a Slytherin would get along, let alone be together.

Dorea sighed, sadly before walking over to the stool where the assistants were starting to measure her. Suddenly out of pure luck, Charlus smiled to her.

"Hello Black, how are you?"

Dorea blushed a bit, "Um…fine, thanks. H-How about you, Potter?"

"The same," replied Charlus, smiling, "How's your family?"

"Oh, they're great. My niece, Walburga and cousin, Lucretia will be starting their first year," said Dorea. "How about your brother? Fleamont, was it?"

Charlus sighed, "He's…annoying. He talks nonstop about being the best seeker in his team."

Dorea nodded, "That's right. Most of the time, he would be able to get the snitch and end the game. Last year, he won the Quidditch cup for the Gryffindor, but didn't win the House cup as it went to Ravenclaw."

"Indeed," murmured Charlus. "He was bragging about it throughout the summer. I'm just glad that Euphemia would come over to visit and make Fleamont to stop."

"Those two seem happy together, don't you agree?" Dorea said.

"I guess," replied Charlus, softly. "Hey, B – I mean Dorea, if I can call you that? Do you…want to hang out or something? You know before we go back to classes."

Dorea blushed bright red, "Ah! Um, well…yes, you can call me by my first name and – yes! I would love to! Oh, but I first need to ask my parents' permission."

"Right, I'll send a message later then," said Charlus. The assistant told him that she finished measuring him and his robes would be send via owl to his manor in about two hours.

Charlus nodded before saying goodbye to Dorea and left.

The sixth year Slytherin stared blankly before squeaking happily. Once the assistant told her that she was done measuring and to get her robes later, she dashed over to her brother who had a grim look on his face.

"Brother! Oh brother! You have no idea how happy I am!" Dorea said, giggling.

"Oh, and could this happiness be something to do with the eldest Potter," said Pollux, smirking.

Dorea nodded, "Yes! He asked me out, brother! Oh please, you must convince our parents to let me go out with him, please!"

"Alright, alright," said Pollux. "Let me think of something. Come on, you still need to get treats for your owl and…a new bag? What's wrong with the one you had last year?"

Dorea pouted, "Orion and Alphard happen, there's no more to say."

"Right," murmured Pollux. "Let's go see if the girls are done yet."

Dorea nodded before the two found Walburga looking over at the cloaks while Lucretia was looking over at the gloves. Arcturus was standing nearby while Irma and Melania were helping them out.

"Are you two done, yet?" Pollux asked.

Arcturus sighed, heavily, "They would have, but they're being picky about their gloves and winter cloaks."

"I'm not being picky father," said Lucretia, sticking out her tongue before going back looking at the gloves.

"That's right uncle," said Walburga, looking at a green winter cloak before putting it back. "It has to be the right style and color."

Pollux and Arcturus sighed while Dorea walked over to them and helped them to find their gloves and cloaks. Once done, Irma told Malkin to deliver the robes to Black manor.

"Harrison and Regulus should've gotten the potion ingredients while Cassiopeia, Madam Yuki and the boys are most likely be at the Quidditch store by now," said Melania.

"Of course," murmured Walburga and Lucretia as they headed to the potion store.

Just as Melania stated, Harry and Regulus were waiting outside of Slug & Jiggers Apothecary. Then they headed to Quality Quidditch Supplies where they found Orion and Alphard looking at the brooms with Cassiopeia while Tom was standing by his grandmother.

"Hey, we're done," said Harry.

Tom turned around and ran over to Harry, "Father, there are a few toys at the front that are really cool! Can I have at least one, please?"

Harry smiled, "I don't see why not. Excuse us everyone."

Pollux and Arcturus nodded before covering their ears as Orion and Alphard whined.

"Aw! That's not fair! Can't we get something too?"

Pollux gritted his teeth, "Behave yourselves! You know better!"

Orion and Alphard looked down sadly.

"Come on, we still need to get the girls cauldrons," said Regulus.

Everyone nodded and finished getting the rest of the girls school supplies. When they were done, it was late afternoon as they returned to Slytherin manor. While the children went to their respected rooms, Zippy informed Harry that the Evans were waiting at the living room.

"Hugo, Lillian, when did you guys arrive?" Harry asked.

"About half an hour ago," replied Lillian. "Rosie helped us move into our rooms."

Yuki grinned, "Well, let's eat. I feel I'm about to pass out."

Pollux and Arcturus stepped back while Regulus whistled as all three covered their neck.

"Oh, don't be like that," said Yuki before calling Zippy. "Have you started lunch?"

"I have my Lady and here's your drink," replied Zippy, handing over a crimson liquid to her. "Will there be anything else?"

"Alert the children that lunch will be ready soon," said Yuki.

Zippy nodded before disappearing.

"Shall we?" Yuki said. She smirked upon seeing Arcturus, Pollux and Regulus sighed in relief while Irma and Melania shook their heads.

"You really like to torture them, don't you mother," said Harry.

Yuki shrugged, "What can I say? Fun teasing is my kind of ideal entertainment."

-Break Line-

What do you guys think?
