A/N: My first vocaloid fanfic. :D It's been lying around in my computer for almost two months before I finally have the heartiness to upload it, so I hope you like it. Now please enjoy it to the fullest and pardon me my bad English, grammatical errors and typo.

Oh, and be warned folks, this fic has incest in it (because I'm twisted just like that, lol. xD). So if the idea offends you, please, due to all respect, do not torture yourself by reading it.

Disclaimer: I don't own the Vocaloid and the legends. I own nothing.

World in the Colour of Ash

Chapter I : The Twins

Long-long time ago, people said that a pair of twins, when born with different sex, were the reincarnation of a passionate couple deeply, madly in love. It was said that because of the strength and the depth of their undying love, not even the heavens up high could separate them. Thus they came back to the world as one. Ever since the very first time their tiny hearts started beating, they had been together. And not to be separated, until the end of their lives.

"… Len," the sleeping boy heard a very familiar voice calling to him. The voice was faint like it was shouted from a place faraway, it barely reached his ears.

"Len!" again the voice called, a little bit more urgently and louder this time. But being the lazy-ass he is, he only turned the annoying voice out of his head and snuggled deeper into his warm comfortable blanket.

"LEN!!" the yell, plus the sudden cold from the abrupt loss of warmth, almost made him jump by surprise. Groaning, the blond cracked an eye open and rubbed it with his knuckles. There in front of him, stood no other than his twin sister with one of her hand on her hips and the other holding the blanket she just pulled roughly from Len's sleeping form.

"What is it Rin?" he grumbled, half annoyed.

"'What is it' you ask? We're almost late you sleepy-pants! Get yourself ready in less than 5 minutes or I'll leave you!" Kagamine Rin huffed in annoyance and turned away briskly, stomping out of his room.

Len watched the back of his sister's figure darkly before she disappeared into the hallway. He could only tell why she was so eager to come to school really early. For heavens' sake, it was only seven in the morning while the school started at 8! Not to mention that the sad school was only 15 minutes of walking away from their house.

Running his fingers through the mess that was his golden locks in frustration, he growled deep in his chest. The reason for Rin's over-excited behavior, especially when it came to coming to school early, must be to spend more time with that damned Kaito guy. The blue haired young man had started teaching at their high-school about half a year ago. And ever since, Rin had developed an ever-growing crush on said man. Unfortunately for Len though, the supposed-to-be-teacher returned Rin's feelings and the two of them had started going out for almost a month now. Their relationship was, of course, kept as a secret from everyone—except for Len who had known all about their affiliation since the beginning of it.

It was so easy for him to crash it, really. All he had to do was to tell to few of his friends, and then the rumor would spread around the school like a wild fire, thus leaving the couple with no other choice but to break up. Simple. Easy as taking a candy from a baby. But tempting as the idea seemed to be, Len didn't have the heart to shatter his cute little sister's happiness. He loved Rin's smile— though it wasn't directed to him, yet—all too much. And he just couldn't stand a sad and broken-hearted Rin. It would just hurt him all the more to have her crying over the young, blue-haired chemistry teacher.

So jealousy as he was, he left his sister had her fun with the Shion guy. He'd just have a close watch over the two of them. But if he ever noticed —even just the slightest hints—that the teacher had hurt his sister, he swore by his own life, the man would live no more.

"Leeen!!!!" a frustrated yell came from the dining room downstairs, telling him to hurry up. With a last yawn, Len sighed and rose up from his bed. Sleepily, he grabbed his towel and dragged his feet to the bathroom next to his own room. Getting ready for yet another boring day at school.

Len looked at the black board in front of the class unseeingly. His brows twitched to a frown and his knuckles rapping the wooden table in annoyance. Earlier, when his sister and he finally arrived to the school, Rin had disappeared immediately out of his sight. It wasn't like he didn't know where she went. He even dare put all of his money on a bet of his sister's whereabouts. She was in the chemistry lab with the man he hated the most in this whole world.

He was sure they weren't doing any inappropriate things. Len knew perfectly well that Rin was much, much too shy to do more than chaste kisses on the lips— though it still ignited his fury, thinking how another man was kissing his beautiful Rin —but it didn't mean he wasn't anxious of what they were doing alone in the lab. Even that Shion bastard —who always presented himself as a man with quite remarkable manner— was a grown man with his own needs.

On top of that, Len's twin sister was very cute and adorable —at least that's how she looked in his eyes — though a little bit short-tempered. And her innocence was just adding up to her attractiveness. Every normal guy would never refuse what little chance to steal a taste or two of those full, luscious lips of hers. So tempting, and almost sinfully alluring.

And looking at how ever since Rin came back to the classroom —just before the bell rang announcing the start of the first period of the class — up until now— the 3rd period — she kept smiling dreamily to herself, didn't help Len lessened his anxiety at all. Kagamine Len just couldn't help but thinking grudgingly of what that one hell of a lucky bastard had done to his Rin. The blond boy would throw his sister a glance or two for every two passing minutes, but still the clueless girl didn't even realize her brother's constant staring.

Messing his blond locks with his fingers in frustration— a new found habit of him— Len shot his burning gaze upon the opened blank note books upon his table.

'Get a hold of yourself, Kagamine!' he scolded himself inwardly and forcefully suppressed his restlessness. Three times he took deep breathes to calm himself down, then he forced himself to listen to whatever the thing their math teacher was blabbing at the front of the class.

As Len was trying his best—though not so successfully— not to fall asleep from the nonsense written on the black board, the school bell rang with deafening decibels. Making the teacher frowned from being cut while speaking, and the students sighed in relieve. Such heavenly sounds had helped them escape the stuck up teachers and their brain-consuming lessons. Cliché as the term was, 'saved by the bell' would always be every student's favorite words.

Just as Len stood up and stretched his arms while yawning loudly, Rin came up to his side and poked him on the ribs.

"Ow! What's that for!?" He protested and quickly rubbed the aching muscle.

"Nothing," Rin giggled. But just a moment later, her smile faltered and a look of uneasy crossed her face for a mere second. Others might miss the tiny hints of troubled look in her sapphire eyes, but not Len. Never Len.

"Hey," the blond boy called softly. "What's wrong?" He took her sister's hand and rubbed her tiny knuckles with his thumb soothingly. A simple, innocent gesture many siblings share.

"Umm," his sister hesitated for a while. "Do you think he will like it?"

Len knew right away, his twin was talking about the bentou she made this morning. Right after Len came down from his room to the kitchen—ready for school— Rin had nervously asked him to try some of the food she had cooked for Kaito while Len was still taking his bath. To be honest, the scrambled eggs were a little bit too sweet, and the sliced meats weren't cooked enough— Rin was never one to cook— but since they were made by Rin herself, certainly Len enjoyed eating them to the fullest.

"Why don't you ask Mom to help you with it?" Len had asked earlier at home, his mouth still full with the scrambled eggs.

"Because I want it to be a bentou that is full with my feelings," Rin pouted. "Why? Is it that bad?"

"Of course not, silly. It's very good." He smiled and messed up Rin's hair fondly. What wouldn't he give to have a bentou full of Rin's feelings to him? He smiled bitterly.

"Aah, that bentou?" Len stopped the flashback in his head. "He'll love it, trust me." Gently he reassured his sister.

"You sure?" Rin's hold on the bentou box tightened in uncertainty.

"Just go and give it to him," The blond boy turned his sister towards the door and pushed her gently. "Good luck," he whispered softly on her ears.

Rin glanced back at him one last time and smiled thankfully. She nodded and ran out of the class, presumably to the Chemistry Lab where she and Kaito often spend their lunch times together.

Right after the sight of her gone, Len's face darkened as he slowly dragged his steps outside the classroom.

"Yeah, he better like it," He muttered slowly to himself. His feet carrying him to the end of the long corridor, where there was the stair up to the roof top. He stepped up the stair and stopped in front of the only door at the end of it, both hands tucked in his pockets. "Or else…" with his right feet, rudely Len kicked the door open, and with long strides he walked outside, where the slightly chilly winds of late autumn blew past his face in greetings.

Sluggishly he threw himself down and laid his back to the wall, his long legs lounged in front of him, one rested over the other. Amid the peaceful atmosphere where above him was the clear sky complete with white rolling clouds and nobody was around to bother him, Kagamine Len inhaled the fresh air and closed his eye for a quite, peaceful nap alone to diminish his annoyance, and jealousy.

-end of Chapter I-

Phew. Done at last. Well, I think this is what we get for listening to the Vocaloid's songs, especially SPICE!, over and over again for the last 3 months. Hahaha. :D This contains my favorite couple, the Kagamine Twins. And not just as a couple, I love them as a couple and as siblings at the same time. Yeah, for me, there's just something so mysterious and fascinating about incest. Lol. xD

Anyway, about the legend.. I get the idea of it from a very very old traditional value in an island in my country, Bali, there I say it. The place's quite popular; have you ever heard of it? But this traditional value is no longer done by them. Because, well, time has changed, and now we know that incest causes bad things to happen to your successors. I mixed the legend with several legends from different countries (including Japan) and thus was the origin of the story's prologue on top of this page.

Oh, and can you guess the origin of the story's title? ;D

Now, so sorry for the terribly long rambling and please do leave review. It can be constructive critiques, questions, ideas or anything, which will be used to improve the story and myself.

Thank you so much for reading! =)

With all the love of the world, BlackBitterRoo.
