Hi! This is my first Vocaloid fanfic so bear with me. I'm not really sure if anyone else has done this but after watching a lot of pv's of this song and reading up on the vocaloid wiki, I kinda had this idea. This is sort of an AU fanfic on account of the fact that much of it takes place in the Daughter of Evil universe but also, I'm writing this with the idea that the vocaloids are not vocaloids but real people since this fanfic is going through the entire Daughter of Evil series. I thought it would be kind of weird if Vocaloids had ancestors ._. So, I hope you like it!

I really really really do not own Vocaloids or the Daughter of Evil series. These are owned by uh, the Yamaha Corporation and the songs in the Daughter of Evil series are owned by Mothy a.k.a Akuno-P. So, uh, there! Please don't hurt me! _

"Ah!" Len shot up from his bed, panting and sweating. He looked around frantically and sighed in relief as he realized he was only in his room. However, still unsure, he looked across the dark room and, sure enough, his sister was sound asleep. Len closed his eyes and ran his hand through his hair. "That dream again."

For the past few weeks, Len had been having the same dream over and over again. He would wake up alone in a place that was pitch black. When he looked up, all he could see was a dark hole in the ceiling that was filled with a wind-up key. However, it would not move. Then, he would hear a voice that would bring him visions. A happy Rin, Miku, Kaito and Meiko, and then bloody crimes that seemed to have been committed by him. Then, suddenly, his hands would be bound by red chains, and his feet by blue chains. Somehow, Len knew that there had to be more to the dream than that, but it would always end there.

He sighed. "I can't take this anymore!" He flopped back down on his pillow with his hands on his head. "I haven't had a good night's sleep in ages!" Len thought for a moment about how he could put an end to this weird dream, but it wasn't long before he groaned and started pounding his head in frustration. "Gah, never mind! I'll just ask Kaito tomorrow morning."

Surely enough, the next morning, after breakfast was finished and everyone else had gone to do their own stuff, Len stopped Kaito and asked him if they could talk. Telling Kaito about his recurring dream, he stopped to think. "I don't really know what to say, Len, I'm not really an expert on dreams." Kaito scratched his head and then continued. "But, I've heard that if you get recurring dreams, then they might have some significance. It could mean something."

"Judging by what you described of your dream, it could have something to do with your past." Both Len and Kaito jumped at the addition of a new voice. Meiko walked into the kitchen casually and headed straight for the refrigerator.

"Meiko!? How long have you been listening?"

Finally finding her bottle of sake, Meiko closed the refrigerator door and took a sip of her drink before answering. "I wasn't listening. I overheard. I was just in the other room you know."

"O-oh. Well, anyways, I don't think it has anything to do with my past. I definitely don't remember doing any of the horrible things that I saw in my dream."

"Well, then it might not be your past exactly. It could be an ancestor's past, or something. If not, then it might even be something related to Rin. Twins do have strong connections, don't they? Maybe you two share dreams or something."

"Maybe...but, that still doesn't solve my problem. How do I make that dream stop?"

"Try-"

"Hey guys!" Rin suddenly called, peering into the kitchen. "Miku says she needs help cleaning up the attic."

"Oh, okay. Tell her we'll be up in a second." Kaito responded. Rin nodded and headed back up to the attic. "Sorry Len. I guess we'll have to finish this talk later."

"Alright..."

"Hey, who knows? You might find something that could help get rid of that dream." Len nodded and followed the two seniors up to the attic. It was dark, dusty, and a little bit creaky. When Len, Meiko and Kaito entered the attic, they found Rin and Miku already cleaning. Miku was busy sweeping and dusting while Rin knelt in front of a large cardboard box full of books and knick-knacks.

"Oh, good! Meiko, Kaito, can you two move those out onto the curb?" Miku pointed to the corner where broke lamps, battered chairs and desks were stacked nicely. Meiko and Kaito nodded and started with the small stuff. "Uh, Len, help your sister sort out all the junk there." Len sighed when he saw how many boxes were still left to be sorted, but joined his sister anyway.

"Miku said that if there's anything that we like here, we can keep it. Anything else goes into this pile here so Miku, Kaito and Meiko can go through it later." Rin said as she examined a headset with a blue butterfly wing on it that was used for a video Miku and Luka had done together. Len nodded and began rummaging through the box. Most of the things in the box were either old merchandise for old albums, props for music videos that they were allowed to keep or books that they had long forgotten. None of these things were things that Len was even remotely interested in. In any case, him and Rin and split their room into sides and Len's side was already messy enough as it was. However, him and Rin had gotten to the bottom of the box, Rin picked up the last two books. They both looked quite old and battered and they were different from the other books. Instead of stories, these two were journals.

"Hey Len! Take a look at these!" Rin held them up from Len to see and he was quite surprised to see that their names were written on the front. "That's so weird, isn't it? I don't remember keeping a diary, do you?"

"Yeah...I wonder what's in them."

"I know! But, I guess we should save it for later. The others might get mad if we slack off." Len nodded and the two got back to work on cleaning the attic. After the attic was finally clean, Rin and Len got dressed to sleep and then the two sat down on Len's bed with the two journals in front of them.

"So, which one should we read first?" Rin asked, her curiosity barely concealed in her voice.

"Hm, let's go with yours first."

"Okay!" Rin exclaimed excitedly. Blowing on the cover to rid the cover of its thin layer of dust, Rin opened it and began to read.

"It has been quite a while since Mother and Father succumbed to their disease. Ruling the kingdom hasn't been so hard. Impose some taxes, instill a bit of fear and suddenly you've got the people at the palm of your hand. However, I've realized that sometimes fear can work against you as well. I had begun to notice a lack of food in the castle and soon discovered the culprit. It seems the commander of the Royal Guard had been smuggling food out to the people! He may have been a valuable asset but such a thing is simply intolerable. But, of course, such a small problem was easily fixed. I ordered my most loyal servant to hunt down the Commander and kill him and, of course, he came back bearing the Commander's head in hand. He told me that he had run into a little trouble but now that the deed was done, no one could disobey me now..."

Rin stopped. "What a horrible Princess!"

"Yeah...c'mon Rin, keep reading!"

"You're actually interested, Len?"

"Aren't you?"

Rin paused for a moment. "...yeah." She finally admitted and continued reading.

There you go! That is the prologue! Len's dream is pretty much of Re-Birthday while the excerpt from 'Rin's' journal, is based on the backstory written by Mothy. Just so you know. See ya next chapter!
