Author Notes: Every chapter I'll let you know the status of the next chapter as well as reply to any questions from reviewers that I think will matter to the rest of you lovely readers. Chapter 2 of A Song of Rebirth is almost complete. Literally a page or two more and it will be done. I had a reviewer ask me to have the shonen-ai noticeable (not hints) as well as have a lemon or lime. Well first of all, I'm a yaoi fangirl. Thusly, the yaoi will be free for all to see! It will most definitely be obvious! As for the lemon, I don't post them on this site if I write them. I try to avoid them actually. However, if I have enough demands for one, I'll do a one-shot and post it on AdultFanFiction rather than here.

Chapter 1

"Rin! Give me back my pants!"

A bolt of yellow shot past the kitchen then turned around and hid behind one of the kitchen's occupants.

"Again, Rin?" A blue haired man asked the small girl hiding behind him.

Rin stuck her head out from behind him. "But, Kaito-nii! He looks so cute in his dresses!" she giggled. A devious look formed on her face. "And I know you and Gakupo-san enjoy seeing him in them." She quickly bolted behind a teal haired girl before Kaito could reply.

"Stop teasing the boys," her new hiding place said. "You know they're too stubborn to admit their feelings towards Len-kun."

"Miku!" Kaito whined pathetically.

The teal haired girl gave him a look of pure innocence that no one believed.

"How do you know he'll wear one of his dresses, Rin?" the only other occupant of the room, a mature looking woman with soft pink hair, asked. "He could just put on a skirt instead."

This time Rin didn't poke her head out, but spoke loudly enough for everyone to hear her.

"I hid those too, Luka-san!"

"Rin!" a blond boy yelled as he stomped into the room. His face was flushed with anger and he didn't even notice anyone else in room as he zeroed in on a white bow just barely visible from behind Miku. He stomped over and pulled out a blond girl who looked exactly like him but with her hair down.

"Why did you take my pants?"

The girl gave him the kicked puppy look. It was something she used often but it always seemed to work regardless. Unable to resist, his anger melted away until only mild annoyance remained.

He let out a breath and calmly asked her again.

"But... Kaito-nii likes it!" she whined, pointing towards the blue haired man who was currently trying to hold in a nose bleed.

Len blushed as he finally noticed the other people in the room. "M-m-m-miku-nee? Luka-san? Kaito-nii? I thought you would all be at the studio by now," he stuttered, fiddling with the lace of the long frilly black lolita dress he was wearing. It was one of the many dresses his master had gotten him to wear for the videos he did with Kaito-nii and Gakupo-san.

Miku gave an amused giggle and patted Len on the head. "Normally we would be, Len-kun. However, Master called us and said to stay home today. He has something he needs to talk to us about."

"Master is coming!" Len exclaimed.

Out of all the Vocaloids, Len was the one who adored their creator the most. The others knew Len's creation was slightly different than the rest of them, but didn't pry any further. The small boy got upset anytime it was brought up.

"Indeed, I am coming by and I have important news for all of you."

At the unexpected voice, everyone in the kitchen jumped in surprise and turned towards the kitchen door. A man in his mid-thirties with handsome features and wearing casual clothing stood in the doorway.

"Master!" Len exclaimed, rushing over and hugging the man.

"Len," the man said with warmth in his voice. "How are you today?" The man paused, finally taking in Len's state of dress. "Did Rin steal your clothing again?"

Len seemed to fluff up like a cat in indignation and proceeded to tell his creator about what happened that morning, including Kaito's nosebleed.

The man laughed and patted Len on the head fondly. "It seems as if you all had an eventful morning."

Master, what did you need to talk to us about?" Luka asked.

The smile on their master's face turned into a frown and he sat down in a chair with a sigh. "Someone has asked me to do a favor for them. Normally this wouldn't be a problem, however, the personally deals with Len's odd history."

The blond boy froze in place, his eyes wide with fear. Their master gave him a sympathetic look before continuing.

"Normally I would refuse out right. You are all my children, I would never do anything to hurt or upset you, but there's more at stake than that. He stood up and paced a bit. "Before I go into more detail, Gakupo will need to be here as he has a choice in this too."

Thankfully for the sake of those there, the door opened at that moment and permitted the long purple haired man into the kitchen. The solemn atmosphere immediately caught his attention. (As did the lovely dress Len was wearing, but that was beside the point.)

"Am I interrupting something?" he asked hesitantly.

The Master stood up and walked over to Gakupo. "No, no. This is exactly what I needed to talk to you about," he gave a small smile and motioned to an adjoining room. "I believe the living room will be much more comfortable setting for this conversation."

Everyone stood up and walked into the living room. Len, however, hesitated.

"Len?" the master asked softly.

A sniffle escaped the short boy and he soon launched himself into his creator's arms. He didn't cry or sob, but his shoulders were shaking with restrained emotion.

The master wrapped his arms around the boy and carefully lifted him into his arms.

"You can stay with me while I tell them," he whispered. "And I promise if we do indeed return to the wizarding world, I won't let anyone hurt you." He walked slowly into the living room and sat down in a love seat. Immediately Rin sat herself down next to him and took the hand of her distraught twin and held it firmly but gently.

"As you can see, Len is upset with what is going to be discussed, but it needs to be done. All of you know that Len's creation was different than yours. What you don't know, is that unlike you, Len existed before I created his body. His soul was not created but transplanted." He looked down at the young boy. "Would you like to tell them or would you prefer I tell them?"

Emerald green eyes peaked through spiky bangs as Len turned his head towards the others.

"I...I can tell them." He turned to face them completely but kept his face down. "My human life was not a nice one," he said with a grimace. "My parents were killed by the dark lord when I was one. When he tried to kill me...it failed."

Luka gasped as she connected the dots. "You used to be Harry Potter?" she exclaimed.

All the Vocaloids knew about the magic world. They themselves were a result of the combination of magic and technology. Their bodies were a combination of robotics and flesh, but as they had souls, they were able to use magic. Their creator had used a ritual he created to create souls and give them life in mechanical bodies. They were able to taste and eat normal foods but the magic broke down the food to fuel their souls and magic. They were as human as possible without being human. Their master wanted them to know about the magic they were created from and able to use, so he let them wander through the wizarding districts as they wanted.

Len nodded. "Yes, I used to go by Harry Potter. You know about most of my life in the wizarding from the books you've read. What you don't know about was the life I went to when school was over." He clutched at the dress he was still wearing. "When my parents died, I was left on the doorstep of my mother's sister by Dumbledore. My mother and her sister were not on good terms. Petunia hated my mother and anything she deemed abnormal. I fell into that category. I was treated as a slave and slept in the cupboard under the stairs until I was eleven. Every time I did accidental magic, I was beaten by my uncle without knowing what I did wrong." He wrung his hands in anxiety. "After the tournament, I was forced into during my fourth year, my uncle took one of his beatings too far and stabbed me in my side with a kitchen knife. I ran from the house and hid in an alleyway, but I was losing blood to fast. I knew I was going to die," he whispered the last part. "It was so quiet and I was so alone in the alleyway. I didn't want to die alone, left with only the thoughts of the betrayal of my friends and the deaths of those around me. So I started singing to myself. It was a song I had heard long ago, when I was little."

"And what a lovely voice it was," Master said, cutting into the story. "It was his voice that drew me into that alley," the man continued, taking over for Len. "I knew who he was the second I saw him, but that didn't matter to me. He sounded so sad and alone as he sung. I decided then to give him a choice. He could die and leave this wretched world behind, or I could give him a new beginning." He smiled down at the youngest of his creations. "He chose the latter, obviously."

"And I haven't regretted it once!" Len interjected, finally looking directly at the others. All of the girls were crying while Kaito and Gakupo looked close to it. Rin launched herself at her twin, causing him to tumble off his creator's lap and onto the ground.

"Master?" Luka asked, waiting for the man to look at her before continuing. "If Len is a pre-existing soul, how is Rin his twin?"

Their Master grinned. "When I took Harry back to the lab, Rin's body had already been finished and was just waiting for a soul. I knew that even with his past memories fogged over as only an imprint, Len would still feel some of the pain caused by them. He needed an anchor and who better to help him forget then a sibling. I created Len's body to be Rin's twin and used a bit of Harry's blood to give them that link when I did the soul creation ritual. The added blood essentially created a sibling soul to Harry's."

"That makes sense. Harry Potter's innate desire to have a family would make a sibling the perfect person to act as an anchor," Luka said thoughtfully.

"Ah-ha!"

Rin jumped up from her seat, a triumphant look on her face as she pointed dramatically at Len. "That makes me the oldest," she gloated haughtily.

Len leap from his Master's lap and marched over to Rin. "Only in body!" he exclaimed, jabbing his finger into her shoulder. "In mind and soul I'm over a decade older than you!"

Rin scoffed, crossing her arms over her chest. She turned her head to the side and murmured something.

The young boy bristled.

"What was that?"

"In case your puny, childish brain couldn't comprehend the first time," Rin said in a snotty voice with a degrading smirk on her face. "I said I have yet to see proof of the older in mind aspect."

"That's it!" Len shouted before dashing after Rin who had darted as soon as she had finished speaking.

Their Master sighed in amusement and relief. This is exactly why he had created the bond between Rin and Len. Rin always knew when her brother needed cheering up and instinctively set about doing so. The down side was the weird things that occurred when Rin was set on doing something. Such as her being able to miraculously steal and hide most of Len's clothing without leaving the house or anyone seeing her do it.

"Len-kun! Rin-chan!" Luka called out.

Things were starting to get knocked down as they ran around the large room. The two teens either didn't hear her or had ignored her.

With a sigh, Gakupo and Kaito gave each other a look. They waited until Rin ran by again before swooping in and scooping up Len. Gakupo had his arms wrapped around Len's upper body while Kaito had his arms under the younger boy's knees.

"Kaito-nii! Gakupo-san!" Len yelped, struggling to escape their grip.

Rin grinned at Len from her spot next to Luka. She gave him a raspberry then stuck her tongue out and pulled down her eyelid at him.

Len's struggles renewed as he tried to escape the two men's grasps to get at his sister.

"Now, Len-kun. You're far to pretty in that dress to run around in it. You might mess it up somehow," Gakupo purred into Len's ear.

The blond boy froze instantly. A bright red blush lit up his face.

"W-what?"

The girls in the group giggled madly while their Master just sighed. Gakupo was smirking down at the blushing boy and Kaito was leering down at him as well.

"Hentai!" the blond screeched and struggled his way free, darting behind his Master's seat.

"Alright now everyone," their Master said, gaining his children's attention. "There's a decision to be made." He dragged Len out from behind the seat. "The reason we might need to go to England is because the wards surrounding Hogwarts have been flickering and fading. With the threat of Voldemort, there is worry over the children's safety."

Miku gave her master a confused look. "But why you, Master?" It was a good question after all. There were many other ward masters out there, so why him in particular?

Their Master smirked. "Yes. However, there are few ward masters who specialize in multiple subjects. My mastery of wards as well as ancient and modern rituals is what singled me out." He was obviously quite proud of his achievements. "It's not well known, but Hogwarts's wards were created by a unique combination of multiple rituals that were performed simultaneously. One of those rituals gave Hogwarts a sentient soul, much like your own. It's why I'm being brought in. I'm the only living being with knowledge of those rituals."

"How long would we be there?" Gakupo asked, glancing at Len who refused to look up from the floor.

Their Master gave a sigh of annoyance. "That's one of the reasons I'm hesitant to go. It could take months or even over a year." He looked up at his creations and could see their apprehension. "Not only would I have to decipher the wards and figure out a solution to whatever the problem is, I also have to find the room the original rituals took place in. Unfortunately, that knowledge has been lost and Hogwarts herself has been keeping its location secret and very much protected."

There was silence as everyone thought the situation over. Len was family and family meant everything to them. It was Len himself who broke the silence. He stood up and looked his master in the eyes. Fear and reluctance filled his gaze, yet a fierce determination over powered the other two emotions.

"We have to go!" Seeing everyone's looks of confusion, he sighed. "Most of the inhabitants of Hogwarts are children. Two of my friends still go there!" he explained. "And despite some of the people in it, I still love the castle herself. It was my first real home. The first place I truly felt safe and loved. I can't let anything happen to the castle or its inhabitants if I can help it!"

Their Master couldn't help but grin proudly at his youngest creation. That determination and courage to overcome his fears was something that had carried over from his past life.

"If Len goes, I go!" Rin declared, latching on to her brother.

Len grinned at his twin. She really was his anchor. He didn't know what he would do without her.

"We're all family. Where one of us goes, all of us go!" Miku exclaimed happily, while throwing herself onto Len.

The others all murmured their agreement causing their master to grin in pride.

"Then I guess we're going to Hogwarts."
