Unlawful Relations

1 ~ Part ~ 1

o~O~o

I am Rin, the proud sister of my brother, Len Kagamine. I have short, choppy blonde hair, not different from my twin.

We started school a year ago. We are both in the same grade, Year 8 – and we used to share all the same periods, be partners for everything and only speak to each other, but the stupid teachers have decided to separate us. Unlike me, who has to stay with all the other people we knew – Len got to go with the other Middle-High group. What a bother. It's not like I'm obsessive; it's not like I am controlling… I just… he's mine. My brother, my friend, mine! So when we were told that Len would only be sharing 1-2 periods with me every day – it didn't go down without objection.

"But he's my brother! We work better together!" I retorted, angry with the Principal's patriotic proposal.

"But Rin, he should –" The Principal began, his words small and useless.

"I don't care! He's staying with me and that is that!" I cut the old man off, a smirk spreading across my angered face. The man stood up and shook his head, grasping the little authority he had.

"Rin, your brother will be in the other Middle-High School group! And that is that! Do you understand? Otherwise I think detention for a month for talking back to the Principal will be enough time for you to adjust," He yelled, forcing me back into my chair. I had lost. There was nothing I could do about it except scowl at him. So, I did, at full force. He grunted and directed his gaze to Len who hadn't said a word – doesn't he want to be with his 'one and only'?

"Len, first period you will have English; secondly, mathematics; thirdly, Chemistry; fourthly, Biology; fifthly, Humanities and sixthly, Japanese Literature. These will change from day to day, week to week; as I'm sure you're aware of. A boy named Kaito Shion shares all the same subjects as you, so he will guide you through your teachers and subjects" The Principal announced to Len. Damn you, Kaito Shion.

We were quickly ushered to the foyer. Sure, I was I 'troublesome child' but I had reasons. Of course I had reasons! Soon enough, the chime of the bell I always dreaded screeched through the speakers. Enough already, I know I have to go to class now! I wanted to squeal at the bell – but of course if I did; it would not just be Len who called me crazy. I walked over to my second period classroom: English. I stand idle while I watch Len silently wave his hand and walk away in the other direction. I feel a mix of emotion as I watch him go. What is it that I am feeling - jealousy, malice, hope, fear, hate, love? I brush away my concerns and walk through the doors; where everybody is sitting obediently and quietly. I have the urge to disrupt them, but I don't. It would only cause me more stress. I take my usual seat and without even bothering to look at the teacher first, I glare helplessly at the empty seat next to me. I then decided to make myself a promise: no-one is to sit in this seat while I am beside it. This is Len's chair – it's the only place he can belong; next to me, as always.

"Rin? Rin? Are you listening?" I hear the teacher yell from across the room. I snort obnoxiously and roll my eyes.

"Yes" I drag on the word lazily, not sending a good impression on Mr. Tonio. I don't care in the slightest about what he thinks. The only thing I can possibly think about his my Len. Did he miss me? Who is Kaito? No-one can steal Len from me. Not anyone.

Because I love him.

o~O~o

I knew the exact thing Rin would be thinking. Is he okay? Does he miss me? Her words were obvious and predictable in my head. I silently chuckled at her nasally whining. Moving classes wasn't all bad – at least I'd get to meet some people – I think. I walked down the outstretched corridor, to my third period classroom… Chemistry, was it? I peered at the signs on top of the doors, wondering where on Earth my class would be…

1D, 4D, 7D, 3E… None, I don't recognize a single number. So instead I look at the labels on the doors.

Biology, Mathematics, Science, Chemistry… There! That had to be it. I made my way over to the sliding doors and pushed it aside. The people were instantly silent as I walked in. I wasn't that noticeable, right?

"Oh, Len; you're here!" The teacher realized; her voice rose slightly.

"Class, this is Len Kagamine. He will be with the second Middle-High group as of now. Why don't you come up here and give us a little introduction?" The woman smiles, waving her hand to the front of the room. I sigh and sloppily walk to the front and turn to the students. I examined them as I gave a poor speech about myself,

"My name is Len Kagamine. I am 14 years old and have a sister named Rin. At home I mostly study or try to annoy my sister. She is nasally when she whines and I usually have to put up with it. Other than that, I am alright with Science and Math but not great with Literacy. Yoroshiku onegaishimasu, I hope to get along with you all," I speak mindlessly. I notice a few people in their seats, those that stand out I vividly remember: A girl with bright orange hair and a scowl that seemed to never disappear, a short girl with pink hair and chubby cheeks, a girl with spiky green hair and a small, slender, teal-haired beauty. Once I realized I had only noticed girls, I blushed and looked away feeling like a pervert.

"Len, I'm sure you have heard about Kaito? He sits just over there – the boy with spiky blue hair – I vacated a seat for you next to him, alright? I am Mrs. Takahashi too, okay?" The teacher speaks quietly so only I can hear. I nod but smirk as the only thing I can imagine is her killing a kid to 'vacate' a place for me. I laugh at the thought of this and search for blue-haired Kaito. It doesn't take me long to find him. I step up onto the platform of chairs positioned like a theatre's seating and weave through several other people. I only notice fine details about the ones I pass: white hair, red hair, black hair, orange hair, red hair again. People, like me, seemed to have unique hair colours as well. I finally reach Kaito and sit in the chair beside him.

"Hi, I am Shion Kaito. We share the same classes… so uh, feel free to ask anything" Kaito says quietly and offers his hand. I reach out and shake it. "Thanks, I am Kagamine Len. Thanks for your help in advance" I nodded, looking back to the teacher, proudly trotting around the stage-like floor in front of a large wall to project movies onto.

"With that, let's watch!" She finalizes, switching on the projector and using a master remote to close the windows and turn off the lights. I sit there for a while in silence, not really caring much about the movie. I look around me, to familiarize myself with some of my classmates. I notice that pink haired girl isn't too far away. Same with the bright orange haired girl and sitting next to them was a white haired girl… who looked far too old to be in Middle-High. I nudge Kaito's arm gently, hoping he doesn't care about the movie either.

"What is it?" He whispers, a sound of relief in his tone.

"Who are they?" I gesture to the three girls sitting beside one another. Kaito smiles in the darkness and pints at the furthest, pink-haired girl first, "That's Kesane Teto, she is fairly off her head but kind enough; the next one is Akita Neru, she thinks she owns the place; next to her is Yowane Haku, she dropped something like 2 grades." Stating the obvious for 'Neru' apparently, "Thanks," I say, resting my eyes on the other students. "No, thank you, for getting me out of the lame video momentarily" He whispers back. I nod and chuckle quietly, I then gesture to the people sitting beside 'Haku' with a one-seat gap, "What about them?" I continue. Kaito nods and replies, "That one is Utane Piko, he is quiet and only speaks to the teacher and his girlfriend," He points to the next one, a red-haired girl sitting next to him and holding his hand – I get what he means now, "Miki, sitting next to him. She is really chirpy but not socially 'accepted' so not many people like her" he finishes. I nod again. 'Socially accepted' seems really harsh. I feel sorry for her. After a good 20 minutes, the movie is finally over. The room lets out a groan of relief and I swear I can feel the teacher chuckling with victory. We all rise from our seats.

"Alright, settle down, settle down. Now it's question time…" Mrs. Takahashi grins. She opens a small banded folder and begins reading,

"The universal indicator for acid is pink, purple for bases but what colour for a neutral reading?" She asks. Yellow, maybe? I forget. I hear someone gasp and raise their hand. I look over my shoulder and see the same teal-haired girl. She was stunning, and possibly smart, too.

"Miku?" The teacher requests an answer from the tiny girl. She smiles and stands up proudly.

"Green, Mrs. Takahashi" She says and to my utter amazement, her voice is spectacular – it sounds like bluebirds chirping and honey sliding down my ears. It's marvellous – she must be an excellent singer.

"That's right. Good job, Miku! Next question, if a new substance is created in this reaction, it is a…?" She looks around the classroom, eyeing the dumber kids. I'm surprised she doesn't look at me. So, to her surprise – along with everybody else's – I raise my hand. "…Len?" She says again.

"A chemical reaction" I say, not getting out of my chair. She nods and smiles. "That's correct. Moving on, an acid added to a base is the same as something and salt" 'Miku' shoots up her hand and is instantly chosen. "Salt" She chirps. These aren't hard questions, but the others seem to know the answers, but can't be bothered putting up their hands. I sigh.

"True or false; many bases are oxides or hydroxides?"

"True!"

"Sulphate!"

"Beta!"

"Gamma rays, Mrs. Takahashi"

"Carbon Dioxide"

"Ok… that's great Miku, but let's give some of the other students a chance to answer, shall we?" the teacher glares at Neru-san, "Neru, what is a solid formed when two clear liquids are added together called?"

"A precipitate" She replies blankly. Everyone is surprised that she actually got it right. "Good job, Neru" Mrs. Takahashi beams, writing something down in her folder.

We all gasp with surprise at Neru's hidden intelligence. I doubt she is that smart, though. The smirk on her face tells me that she is playing dirty. That one, I don't like.

"Alright… now for those who didn't answer any of my questions – and I know who you are – you are to write a 600 word document on precipitates, got it?" She laughs. But she isn't joking. Thank God I put up my hand. The bell rings for rotation and I rise from my seat.

"Thanks for your help. I have to meet up with Rin, or heads will roll. Sorry, see you later!" I call, running out the door. Kaito waves but I don't really notice. Knowing Rin, she'll probably pin some freshman up to the wall demanding me. "Oni! Oni!" I can hear the children cry in my head. I rush over the food court, which is fairly far away. But I make it, and see Rin sitting alone at a table. I make my way over to her – she's pouting, as usual.

"What a surprise. I thought you were going to abandon me like you did with class today" She hisses. I roll my eyes. "Like I would" I reply. She giggles and reaches over to me, holding out her hand. What am I supposed to do? I rest my hand in hers and she lovingly rubs it slowly. "Rin! Stop it!" I snap. She looks very disappointed in my words, "Why?" she asks, acting oblivious to the suspicious eyes crowding around us. "Because!" I snatch my hand away. "Do you realize how hard like, everything would be if people thought we were going out? That's like – incest!" I hiss. Rin retreats to pouting, but I know she understands. She just doesn't want to believe it. "Hey, get me a warm salad, will you?" She requests. I nod and trod off to the salad bar. There is a long line of girls, all skinny as sticks. I sigh and shake my head disapprovingly. I suddenly spot the teal-haired girl bounce past, heading for the normal kiosk – crowded with guys and obese people. But, 'Miku', was slim and slender. She must order something small.

"One pie, leek soup and soda, please" I hear her order. She must work out a lot then. But, her body isn't muscular either. Weird…

"Next" The anorexic salad-bar operator whines nasally. She reminds me of Rin.

"I'll have a warm salad with oranges instead of mango and… a garden salad with two bananas and 2 sodas" I say. The woman nods and shoves her hand in my face.

"$16, thanks" She croaks. I obnoxiously shove the money in her hand and walk across, letting the other anorexic girls order one apple. It's a sad reality, really, that some people are like that. But, in my case it's fortunate; because if every girl orders one leaf of lettuce, my proper salads are done in no time. "Here you are" Another girl hands the two salads, two bananas and two sodas to me. It's a lot to carry… what a hassle. I walk carefully back to our table being careful not to drop such delicious-looking bananas. I drop them all down on the table and Rin snorts.

"Bananas? Again?"
"Look who is talking; no-one has oranges in salads" I retort angrily, ripping open the side of my delicious banana.

"Yes they do!" She snaps back, shoveling a pile of oranges, cheese and lettuce in her mouth. How disgusting. I don't know how she does it.

I take a bite of my banana – it's very good, as usual. Rin seems pleased with her salad as she cracks open her soda. I sigh as I watch her guzzle it down with no femininity at all. She is so weird, but very cute. I peer over her shoulder and notice Miku again. She is sitting with another girl… the green haired one. That one is pretty too, same with the womanly figure sitting with them. What an unusual group; I wonder what they have in common? By the look of them, they probably all have partners. Maybe that is what they have in common…

"Len? Are you listening to me? Hey! HEY!" I feel a sharp pain on my head.

"What was that for?" I yell, yanking my soda bottle out of my hair. Great, now I will repeat science class with the volcano experiment we did last week by opening this bottle! Suddenly, I am confronted with a very devious idea. I put the bottle in the middle of the table, tilting it forward, I take aim and… FIRE! I rip away the lid from my blown up soda bottle and with a loud…

SPLASH!

… I know Rin is most definitely going to murder me. I mean literally cut out my lungs with a Stanley knife.

It takes about two second for her to process what I have down, slowly titling her head to her soaked top.

"LEN! I AM GOING TO KILL YOU!" She screams with the whole room going silent and watching what on earth the crazy girl is going to do next. She thrusts her hand and grapples my tie. Maybe she is an Oni after all. I quickly leap from my seat and luckily enough – instead of suffocating me to death – my tie comes away and Rin is left dripping with a golden tie in her hand. Scowling at me for a moment she breaks into a sprint. I panic jokingly and begin to run to the outside, where people are sitting on the grass eating. I leap over several groups as I hear Rin screeching ferociously behind me. I weave around more people and quickly dash up a staircase to a large oval. I look behind me; Rin is still determined to kill me. Persistent, I'll give her that. I run past several guys, playing rugby as they all complain as I sprint through their game. But, they instantly stop as they watch Rin running after me screaming obscenities and attempting to whip me with my own tie. I suddenly choke out a wild laughter as I notice I still have the soda in my hand. Almost like insult to injury, I take a long sip from it and then toss a fair amount on Rin – which as presumed leads her into a full-on rampage of fury. I don't know whether to be scared or bursting with laughter.

You have to love her, my sister.

A/N: I hope you guys liked it and don't forget to review and read the next chapter by Unsub! Just a couple notes:

Oni (鬼) in Japanese means 'Demon'.

Also, a quick brush over the characters: Teto, Neru, Haku, Kaito, Len, Rin, Miku, Antonio (Mr. Tonio - English Teacher), Mrs. Takahashi (Len's Chemistry teacher) and a few more assorted randoms here and maybe to come. I can't wait to write Chapter 3!
