Chapter 1: The Scientist Succeeds, but Project 2 is delayed

"Arigatou...anata ga watashi ni kureta...subete...Arigatou...eien...ni...u...u...u tau..."

*Beep* *Beep* *Boooooooooop* *Kokoro fixed; Beginning Revitalization stage*

"Thank-you, computer..." The blonde 15year old boy spun around in his chair, petting his orange calico cat in his lap, "How much longer?"

*5 Minutes and Counting*

"Lovely...Now I can work on project two..." The boy cracked his fingers, "HOW TO GET A GIRLFRIEND!"

"...Meow." The cat meowed at him, as if mocking him for his next project.

"...Shut it cat." The boy could tell the cat was mocking him, "If I can revive my father's prized project, this lonely robot, I can do anything! My father died making her heart, but I can stabilize her! Fix her! Improvements!" The boy would've had a lightning background during this if this were an anime. The cat jumped onto the computer, pressing the keys.

"Meow, Meow, Meow-Meow!" The cat still mocked him, pressing random buttons. The computer made unusual noises.

"Cat! Get off!" The boy tried to grab the cat, but the cat hopped into the tank that held the robot. The boy began to panic, "Aw shit, cat! REALLY?" He began hammering the keyboard. After a whole minute, the tank developed a thick blue condensation. The boy hammered the keyboard more...until...

*Process complete. Opening Tank*

The tank opened slowly, releasing a thick blue fog. The boy covered his eyes, unsure if the fog's chemicals would irritate his eyes. A shadow, humanoid, stepped out, two humanoid shadows...? The first one was clothed in orange, with thick platinum blonde hair. The other, he couldn't really see...

"...Who are you?" The boy asked the mysterious girl who seemed to be 17.

"I am SeeU, Master! Also known as...'cat' my unoriginal master!" The girl smiled. The boy looked annoyed, and shocked.

"...You were a cat...now...you're a human..." The boy smiled to himself, "Mother flipping genius...!"

"...Where...am I?" The boy looked up again at the tank, and quickly had to remember something: she was a robot. A female robot. More specifically, a NAKED FEMALE robot. The robot girl had yellow blonde hair that was short, cut below the chin. Her bangs were in her face, covering part of her blue eyes. And her skin was pale, with yellow painted nails.

"Ah-hem!" He regained composure, willing to explain to the girl once certain things were taken care of, "Rin is it?"

"...yes? Are you-?" Her face lit up. Rin, the robot, had missed her Master all these years. Loneliness, yes, that's what it was called. That's what she felt without her Master.

"No, but, I'm his son." The boy explained to her, "I brought you back to life, to take care of you like my father would've wished." Rin seemed to understand, for she stood up and bowed, "...I'm Len...Len Kagamine...Um..." Len looked to SeeU, who was sitting in her cat bed oddly enough, "L-Luka!"

Within a moment, a maid older than Len appeared. She wore a basic black dress with white off the shoulder sleeves, boots, and a necklace. She had long pink hair in a ponytail with pale blue eyes. She was about 21, maybe older. Rin looked at her, confused.

"Yes, Len-sama?" Luka turned to Len, her master. She didn't notice her Master's red face, SeeU, or Rin.

"...Please take Rin to get new clothing..." Len gestured to Rin. Luka then noticed her.

"I see, your project was successful." Luka nodded, "A course. Where is the cat?"

"...The cat is now human..." Len gestured to SeeU, "And should NOT be in the cat bed!"

"Nyah." SeeU stuck her tongue out at him. Len was forced to ignore her.

"I see, Len-sama..." Luka nodded, and turned to Rin, "Please, Miss Rin, come with me." Rin stood up, and followed Luka.
Luka led her down the halls of the mansion. They were beautifully decorated with pictures, rugs, and stands with rare artifacts on them. Rin looked at them all as she was led down the hall. Luka opened a door, and gestured Rin to go in first. Rin did, and sat on the bed. The room was also adorned well with basic necessities. Luka rummaged through a closet.

"My associate, Gumi, is getting more attire for you, until then, please suffice with what we have." Luka apologized to her in advance, even if Rin didn't care what she wore.
Luka had picked out for an outfit a white A-line dress with ruffles and black lining at the top. She put black barrettes into the robot's hair so she could see well. Luka had also gotten the robot to wear underwear and a bra, despite Rin's confusion on its purpose.

"...What's the purpose of it?" Rin asked Luka. Luka smiled. The naïve-ness of this girl touched her.

"To hold up your breasts, Miss Rin. You've grown a bit while in that container." Luka put lip gloss on her lips, dolling the robot up. Rin didn't object and was content with the flavor of the gloss, "It's been a long time...The master was born to a rich woman who was single and went to one of those banks. The donor was apparently your creator..."

"...Len is my Master, since he is my Master's heir." Rin smiled, "As long as I'm taken care of, creator-sama will be happy." Luka nodded.

"The master inherited his fortune's, including you, his prized achievement..." Luka explained further, "It became his goal, about two years ago, to revive you after reviewing the data. You now have a heart...A stable one..."

"...Kokoro..." Rin smiled as she said the word. No wonder she was overcome with emotion like before she had passed out. Well, she thought she passed out.

"Done...I put a cute ribbon in your hair..." Luka showed her in the vanity mirror. It was white, like the one on her headband. Rin liked it, "Let's take you to Master, and...His...cat (?)."

Once again, they returned to the lab where Len was reviewing some form of data on Rin. He didn't even notice them walking in, as usual. This always happened when he was pre-occupied with his projects.
Len, as mentioned before, was the product of his mother going to a sperm bank since she was unlucky with men. Turned out, he had inherited the genes of a scientist, and a genius one at that. A course, by the time he was only 4, the man had died of old age. And, after some DNA tests, Len had inherited his fortune as well. His mother, Lady Meiko Sakimira, was already a rich woman from having a fashion line for all ages and perfumes, and now, her son, Len Kagamine (His last name from his biological father), was also rich for just being related to someone. Len had also finished school as of last year, since he was genius after all, so he was in the right position for someone his age.
Len was also fairly decent looking for his age, despite his issues with getting a girlfriend. He had blonde hair that was styled to look messy but professional, and in a small ponytail. He had dark mint green eyes with a hint of blue and brown if one looked closely. He typically wore a white lab coat, fitted to fit him correctly so that it ended at his mid thighs. He wore a white button shirt with a black collar and denim jeans, with black and white sneakers he loved to wear. He was often told he resembled his father when he was younger.

"Len-sama, I've dressed Miss Rin." Luka announced. Len spun around his black chair, smiling. Much better. He thought.

"I'm having Gumi pick up clothing specifically for you while she's touring Europe." Len told Rin, "She'll be home in a few days...Do you feel different?"

"...A little." Rin replied, "But, I assume it's normal to wonder where you are, and what has happened since blacking out."

"R-right..." Len nervously laughed, "I'll explain it soon, what I meant was, to feel different in your personality."

"Oh...Well..." Rin pondered silently for a moment, "...Will my bed be fluffy?" She asked. Len nodded.

"As Miss Rin wishes, yes." Luka replied.

"...Will I be able to do the eating-thing?"

"Yes."

"I think I'm hungry then. My insides are making noises." Rin put her hand over her stomach. She wasn't used to any of this. It was written on her face.

"Alright...My mom should be home..." He heard the front door open and close, "Speak of the devil..." He muttered and spoke to Rin, "Dinner should be done any moment. You can meet my mom, sisters, and my lab assistants."

Luka walked in front of the two blondes, escorting them to the dining room. They went down a different hallway with similar décor to the last one. They stopped at some large cherry oak doors, which Luka opened. Inside was a dining room with a 4 foot long table with bouquets of flowers and china plates with silverware wherever a chair was. On the ceiling hung a chandelier that shined different colors. Rin gawked a little, impressed and excited by these surroundings.
At the end of the table was a young woman in her late 30's, but looked to be ten years younger. She had short brown-red hair that was very shiny from hair products and brown eyes. She wore make-up, typically a blue smoky eye with black eyeliner, red lipstick, and a faint pink blush. She wore an elegant red dress that came to her knees and a black plaid coat that covered her upper body. She had on red 3inch heels.
Beside her on the left was a teenage girl of about 16, who was pressing buttons on some device. She had her amber blonde hair in a ponytail secured by a blue band, and hazel eyes. She wore a white tank over a thin, skin tight blue shirt and black rolled up shorts. She had on blue sneakers and looked annoyed at the device.
Then, on the woman's right, was another girl, who seemed to be 13 and eating a candy bar. She had curly blonde hair similar to Len's in long ponytail with blue eyes. She wore a fluffy pink hoodie with stars on the pocket and cat ears on the hood, a white sailor shirt with a black collar, a black pleated skirt with pink trim, and pink flats. She was adorable.
Besides the cute one was a small child of about 6 who had black hair in ponytails with yellow ribbons and brown eyes. She wore a red overall dress with pockets over a white shirt with poufy sleeves. The child wore white sneakers.
Beside the annoyed teenager was a man younger than the woman at the end. He had long purple hair in a ponytail, a long one, with matching purple eyes. He wore a striped black and blue button up shirt with a white tie, and black trousers with dress shoes. He was working on what Rin assumed to be a smaller computer.
Lastly, there was a woman about the man's age wearing glasses, also working on an even smaller computer with a touchscreen. She had long straight blonde hair with violet eyes. She wore a white lab coat similar to Len's with a black laced blouse and tan trousers. She wore black boots with a slight heel.

"Welcome Home, Mother..." Len greeted the woman at the end of the table, "This is Rin, the robot Mr. Kagamine created." Len gestured to Rin. The woman got out of her chair and went over to Rin. Luka went into the kitchen, behind black doors.

"It's wonderful to meet you Rin." The woman shook Rin's hand with a warm smile, "I'm Len's mother, Meiko Sakimira...You can call me Mom, or Meiko." She gestured to her 3 daughters, "These are my daughters, Neru Eloise Akita, Lenka Avanna Kagamine, and my youngest, Yuki-Kaai Meredith Hiyama."

"It's nice to meet you." Rin bowed. Neru, the addict to her small electronic device, put her device away.

"Neru's my older sister, Lenka's my twin sister, and Yuki-Kaai's my youngest sister. We all have different dads, except me and Lenka obviously." Len's explanation made Rin embarrassed to think that her Mistress (Lenka) was a younger sibling, "These two are my lab assistants, Dr. Gakupo Kamui and Dr. Lily Masuda."

"She's amazing, Len!" Dr. Gakupo sipped his coffee, impressed by the teenager's achievement.

"Rin...Sit next to me, please." Dr. Lily invited her to sit by her. Rin did as told. Len sat next to Gakupo across from Rin.
Dinner was very elegant: a seafood pasta with sourdough garlic bread and a fancy salad. Rin enjoyed the pasta the most, for whatever reason there was for her to like it the most.

"Len, where's the cat?" Lenka asked her twin. Len nervously smiled.

"Um...the cat's a human." Len said. Neru rolled her eyes.

"Len, stop lying." Neru told him, "You said that about the turtle and that was a lie."

"I have proof!" Len pointed his finger at her, "And the turtle was an accident."

"Nya! Food!" SeeU came in. Len gave Neru a look that said "I was right" and Neru rolled her eyes. SeeU was given her own plate of fish, which she enjoyed.

"So what's wrong with the robot?" Neru glanced at Rin, "There's always something wrong with your creations."

"There's nothing wrong with her." Len bluntly said, "She's normal. Normal for a Robot."

After dinner, Len had gone back to his lab to check on the data. He had sworn he had seen something unusual in the data, so he decided to check. Everything seemed to be normal: normal heart rate for a robot, proper wiring, proper memory, etc. Then, he found it.
"Aw Shit..." He slammed his head against the keyboard, "...but...how-...Right...my cat...human...pet...thing. Well...it's only activated by an increase in pheromones and estrogen..." Len logged out of the computer, fearing no real problems here. He decided to go check on Rin.

"...Pajamas..." Rin was naked, figuring out which of 3 nightgowns Luka had pulled out for her (before leaving to clean) she should wear. There was a pink one with frills and bows, a pink one with lace and polka dots, and a blue one with white polka dots and lace. She felt as if it did mattered what it wore. Perhaps this what her Master had once referred to as 'Fashion Opinions.'
Finally she decided on the blue one, but...as she picked it up...

"Aw, Rin, I need to-"Len was now frozen, and red faced. Rin's face got red as well involuntarily, and in a moment, she was surrounded by a blue light that vanished as soon as it reappeared, "...What the..."

"Nya?" Rin looked at herself in the mirror: She had black cat ears, a matching tail with a yellow ribbon, and wore a new outfit. She wore a white shirt with a black sailor collar and poufy sleeves, white lace gloves, skin tight black shorts to her mid-thigh, a white fluffy open skirt with a yellow belt, and white shoes. She looked up at Len, obviously confused.

"Oh boy..." Len sighed. He had a bad feeling about all of this, and a good one oddly enough, "How do I explain this..." he looked up at the ceiling, "There went working on Project 2..."

Now, you may wonder how this happened...I was watching Magic Kitty Len Len and looking at the lyrics for Butterfly on Your Shoulder for Vocaloid House when I clicked on Kokoro for the hell of it. This is how the story was born. I promise shirtless Len scenes. ...Because shirtless Len is hot. ~Kingdom Mitsumi
