Hello everyone! I'm Yuki Kagene, and this is my first story. Len and Rin's part of the story will be more serious, whereas when I get to Miku's part, it's a bit of comedy, including an assassin called Dell (yep, Dell Honne) who complains about his sister Haku a lot, and how he doesn't enjoy being an assassin. Yeah. Well, this is the first chapter of my story, Reasons! Hope you enjoy :D I updated this because it was only like, 800 words long before.

Len Kagamine was sick of this 'prince' business. He had been challenged with a noble task, one of rescuing the Princess of Lunia. Len, however, wasn't so keen on saving her, for several reasons: one, he didn't even know her, so, really, what was the point? Two, he was tired. Sure, he could go tomorrow, but he wouldn't sleep well, and to Len of Necrona, sleep was way more important than saving some idiotic Princess who'd managed to get herself captured by assassins who probably had the mental level of single cell organisms. Unfortunately for the Prince, these thoughts were going on while his father, the king was telling him how he should rescue her, how, of course she'd fall in love with her dashing saviour and had even started planning for the wedding. Well, Len did know his father was talking, he wasn't exactly paying attention. The king soon realised this…which resulted in Len being yelled at till he couldn't hear much. And to be honest, Len Kagamine didn't know how he could go on this quest with no eardrums left.

Len's sister Rin was listening in to this entire conversation, and had a sour look on her face for every minute of it. She never got any quests to go on, because she was the dainty younger sibling who should be protected at all costs, because she would rule one day. You see, in Necrona, the female heir to the throne always becomes Queen. That's why Len and Rin weren't on particularly friendly terms – because, even though it would 'take too much effort' Len was still pretty bugged that he wasn't going to get the chance to rule over a mighty kingdom of his own. Although, Rin would let her brother have the throne, but she wasn't even allowed to suggest it. Len wouldn't listen and say she was teasing him, rubbing it in his face that she would rule. Rin felt a bit misunderstood, really.

Len stormed out of the room, opening the door straight on his 'beloved' sister's face.

"Don't just stand outside the door, little sister. You're going to be a great ruler if you can't even get it through your thick skull that just standing there to eavesdrop isn't very sensible." Said Len bitterly, walking past her, and not even waiting for a response.

"But Len I-"Rin tried to explain, but to no result. This always happened. Len never listened to what his sister had to say. The thing was though, Rin didn't actually dislike Len. She remembered when he didn't understand the mere concept of ruling, when he would read her stories of magical lands, princesses and fairy godmothers. She remembered when he would take her outside, and they would lie in the garden peacefully, spotting shapes in the clouds, rabbits, dragons, and occasionally Rin or Len themselves. But on Len's 10th birthday, when Rin was 8, everything went wrong, Len was told how he would never be king, like they'd told him from a young age. Len still didn't realise what this meant, that came a few years later, when he guessed this was basically saying he wasn't important, that he wasn't needed. All Len understood was that Rin was getting something he couldn't have, and between the siblings, this was previously unheard of; when Rin got a new toy, Len would too, if Len got new clothes, Rin would too. Until now, everything was distributed fairly. Rin sighed. She missed those days, before everything changed. Rin heard Len come back over.

"You're still standing there? I told you to move." Len snapped

"Sorry. I was thinking about how we used to be" Rin replied sadly. At this, Len paused.

"How we used to be?" Len said, confused.

"When we didn't know about any of this ruling stuff, when we were like best friends, when there was only Rin and Len, never apart."

"Rin, I know, I-" For a second, Rin thought she'd managed to get to him. "I think you should stop living in the past. As much as I hate you, I don't want you to tear yourself to threads thinking about what could've been."

"Len, I'm not. Hang on, you don't want to go on that quest, right?" Rin, said slightly perkier.

"Yeah…I don't."

"Well then, I could go for you! We are almost identical, even though we aren't twins!"

"There you go again." Len spoke.

"What do you mean?" Rin questioned, slightly puzzled.

"You always want what I have, and I want what you have. I guess that's how our life's going to work out. With neither of us happy. Goodbye, Rin." Len turned around, not going into the room behind her. Instead, he headed upstairs, to his bedroom, where he spent most of his time. Rin was slightly happier though. It was their first conversation in months that didn't end up with them yelling, or not listening to each other. She smiled slightly, but went to the nearest seat and sat down, continuing with her previous line of thought.

What Len didn't know, however, is that even if she had never existed, if she had never been born, he still couldn't have ruled. It was explained to her at age 10– her brother had something dreadfully wrong with him. One minute he could be his old, lazy, miserable self and the next he could be a psychotic lunatic, violent and unpredictable. Of course, Rin was almost positive Len knew about his…problem and had done for a long time. Either that, or he thought that horrible day happened while he was sane.

Rin could never forget that day. The first day they all knew there was something wrong with the previously happy and caring prince. She still remembered the afternoon it happened, they'd all sat around the table and talked about futures, about how Rin would rule, not Len. Rin supposed that could be why Len hated her, because she started it off, she just had to start an argument. Len always did have a short temper, but was usually kind and thoughtful. Usually, Len losing it meant a few harshly spoken words, then he'd be his old self again, laughing about how silly he was. But Rin had to try and tease him about her being queen, saying he would have to complete her every command, be her personal assassin – Len had laughed at that part. But then her mother had to join in, had to take it too far. Their mother, Lenka, was always immature, she liked to mess with people, including her son. Rin still recalled what Lenka had said, and Len's response

"If Rin is queen, then I'll love her ten times as much as I do you!" Lenka had said, with a laugh.

"You'd still love me though, right?" said Len, sounding slightly annoyed.

"I don't love you now, you silly boy. You are useless, you do realise that?" Lenka said with a snap. Rin was shocked at that – she knew how Lenka felt about her son, but Lenka had never said anything to Len, knowing how it would hurt him. Rin was also positive that Lenka knew this would set off Len into one of his infamous tempers.

"You could be murdered now and I couldn't care less! I hate you, child. " continued Lenka. Rin was sure Lenka hadn't expected those words to be her last. She recalled Len screaming, and then there was a horrible silence. She thought of Len leaning over the table, to pick up the carving knife and then- Rin shook her head and started crying. She'd never been able to get past that point in her memory. No matter how much she tried, it would never go past that. Always just before it happened – because even if she couldn't remember it, it still occurred. That dreadful day was the day Len snapped – and killed their mother.

A/N: How was that then? I would appreciate reviews, constructive criticism wouldn't be too bad. Oh, and yeah, Len has more than a few issues in this story, haha. If anything is spelled 'wrong' it's because I'm British.
