Chapter Note: My little sister gave me a challenge: "…write a Vocaloid FF with the main genre being Crime, I want Len to be one of the main character's, hint at my OTP, must be written and complete during October, must only be six chapters long, give me a ending I won't suspect and have all chapters NOT edited – don't even glance over them." Given that piece of information, I thought that I should post this during October - what's a 'scary' month without something to scare you? And anyways, I have nothing to lose *shrug*
Chapter Note2: This isn't based off of anything (not that I know of), so if it reminds you of something, say, you read or watched (heard), then it's purely coincidence.

Chapter One:

Deciphering The Texture of Emerald

.[October 1st].

"...died roughly around midnight, on her way back to her home from a party at her friend's house..." the man in the television went on, informing the world through scripted lines that, yet again, another girl has fallen victim to the brutal serial killer.

"Not again... It's getting dangerous out there you two..." A woman spoke up as she clicked off the television, triggering her kid's attention.

Her daughter gave a sigh with a roll of her eyes as she swayed her legs side to side, nonchalantly kicking her brother, "It's always been daring outside, Mom. I mean, any day I, or we, could walk out and be shot for all we know."

The blonde women gasped at her daughter and her casual manner, "Rin! Death is no light-hearted matter to wave about!"

"Yeah, yeah," Rin gestured a dismissing hand in a weary motion, "We get it, you don't want us to die like dad: A hit and run, or so the police say."

Len bumped his right knee against hers, signally her to shut her mouth as his eyes remained focus on their Mother.

Rin gapped her mouth shut and huffed at her brother.

"What she's trying to say, Mother, is that we know the danger that lurks in the shadows and that we're careful when venturing out, so you shouldn't worry too much." He eased his Mother with his choice of words, and frankly, it worked.

"I know..." their Mother let a dry sigh escape her lips, "It's just... I'm scared for you two. News has it that the killer is after girls, preferably teenagers." Her eyes focused on her daughter who was currently daydreaming and looking elsewhere, "Just... be careful when you two go out, try to stay together or with a group and always leave your phone on."

Since Rin wasn't acknowledging their Mother, Len responded for the both of them with a nod of sympathy, "I promise, Mom."

She released a thankful sigh, "Thank you, Len... -" Just then, the home phone rang, "I'll get it." She gave one last gaze toward her daughter who found her painted nails fascinating, then turned and left.

As soon as their Mother was out of sight, Len bumped Rin's knee harder than last time, "Please don't act like a spoiled brat, Rin."

Rin jerked to face him, a scowl upon her features, "I am not! I'm just being frank! She needs to get over dad's death; it's been six years already!"

Len watched his sister throw a trivial tantrum. He understood what Rin was trying to say, but at the same time, he didn't appreciate her choice of words. Their Mother had lost the love of her life right in front of her, in less than a second – so of course it was going to be hard for her to move on.

Though, on the other hand, Rin was never fond of their Father for some strange reason (and Len had always thought the same for their Father; he never really talked much to Rin).

The police had labeled his death as a hit and run since he didn't have anyone who he had ever angered nor disrespected.

In fact, he had died on the night of their parent's anniversary when the two were walking back to their car late at night, ready to go home. Then, out of nowhere, a gun shot four times and before their Mother knew it, their Father had shielded her from the bullets at his cost.

Len couldn't comprehend quite well as to why Rin hated (not disliked) their Father, but he guessed it was because he never paid much attention to her, but to Len.

Favoritism might have been it.

"Rin, try to understand Mom's feelings." Len coaxed, gaining Rin to silent her mutters and think over her words.

"...I get it," Len was about to sigh in relief, but Rin continued, "But she doesn't have to control our lives because of it. I mean, we have a curfew and we're seventeen, not to mention the time is eight o'clock! That's too early!"

Len wasn't a fan at the time either, but he had placed his-self in his Mother's shoes and understood her point of view. The thing was – Rin wouldn't do that.

So he had to choose his words carefully or they could back fire on him.

"Rin, let's think of it this way," he started, grabbing her attention, "Visualize if Mom didn't care at all after Dad's death, and quickly started dating too. Don't you think that'd had been much worse; meeting new faces every once in a while?"

Rin pouted her lips but Len wouldn't allow her to speak just yet.

"Or you could think of it this way, in someone else's shoes –"

"You know I suck when I have to think from someone else's view!" Rin whined.

"– I know that, Rin. But just think. Okay?"

Rin nodded.

"Good. Now, picture our Mom being the type of women who didn't feel after that accident and begun drinking her feelings away, not giving us a curfew, not giving a care for our grades or heath, not -"

Rin held a hand out, her cerulean eyes glassy, "It would hurt..."

"Exactly. There are teenagers, kids even that have Mother's like that; Mother's that cut off all their emotions because of death. But we have a Mother who still feels, maybe a little too much, but she honestly cares for us, Rin. Be thankful for that, 'cause I know I am." Len finished, his eyes mirroring the emotions Rin felt.

Rin hung her head in shame, "I... I get it. Sorry for being a brat..." She apologized.

Len let a small laugh escape, "There's no need to apologize to me, Rin. Go say sorry to Mom."

Rin made a face but her eyes reflected her thoughts, "Fine," She mumbled as she rose from the sofa and shuffled her way to the kitchen.

.V.

Minutes later, Rin came skipping out of the kitchen, a smile etched upon her lips.

"I see that everything went well," Len smiled.

"Yup!" Rin beamed, prancing over to her brother who surfed through channels one by one, "She said that it's okay once I explained it to her."

Len hummed his response whilst nodding.

Rin pouted, but quickly dismissed it with a hop in her step as she skipped over to Len and embraced him from behind, "Thanks for helping me and not walking away..." she whispered, leaving a kiss on his left check, "You're the best brother a sister could have!"

Len laughed as he ruffled her hair, bringing his other arm to hook around her neck and tip her over the sofa, "But of course! I don't read those brother books for nothing!"

Rin giggled, "As if there're books like that for sale!"

Len gave her a blank, "I have you know that they help a ton."

She rolled her eyes, playfully pushing Len aside, "Yeah, uh-huh. And the most helpful one is titled 'How to be a Great Big Brother', right?"

Len blinked, "How'd you know?"

Rin busted out in laughter; he sounded too shock for it to be a joke, "You're s-serious?!"

The blond boy looked off to the side as he released her from his hold, allowing Rin to sit up straight.

"Oh my God, you are!"

"I blame Kaito! He gave me it!"

"You don't take things from Kaito! That's, like, the first rule of handling Kaito!"

He couldn't save face, so he chose to change the subject, "There's nothing on. Go get an anime or something to watch."

Rin narrowed her cerulean colored eyes at his attempt at changing the subject, but shrugged it off, "Fine. But I get to choose what we watch!"

Len couldn't argue with her, so he allowed her to jump off the sofa and crawl over to the DVD shelf next to the television.

"Something classic; something humorous; something to scare you, or something with romance? Oh!" Rin jumped on the floor, bobbing herself up and down, "How 'bout some good 'ol BL, ne?"

"No." Len snapped.

"Hm, so BL it is..." she appeared to be talking to herself out loud, but he knew she was doing it on purpose. Curious, Rin peered over her shoulder to see a very pale Len, "Fine, I'll choose something with action."

"Wai -"

"As in fighting action, not that action, Len." She smirked at his redden face.

"Pfft. I knew that."

"Right, sure you did." Then she faced the DVDs in search for an anime.

Seconds flew by and soon, Rin has found the anime series to watch.

"How long do you think it will take to finish re-watching this?" Rin held up the first volume of Inuyasha.

"Under a week, depends on our breaks and such."

"But it has a lot of episodes."

"I stand by my statement. I mean, the day's still young." He motioned to the front window and clock that stood next to it, reading five o'clock.

"No sane teenager says the day is still young." Rin deadpanned.

"Ah! But I said it with a different sense -"

"Just hush," Rin shushed her brother as she took the DVD out and placed it in the device just as Len's phone went off.

She turned and watched Len keypad his phone and open up the text message; a smile upon his face.

"Who is it?"

Len jumped, "Oh? Uh, it's... the gang. They want to know if we're free to hand out tonight at the local karaoke club."

Rin frowned at her brother's words for he didn't answer her question, but answered it all the same, "What time?"

"...Says at seven. Why?"

"Think Mom would allow us?" How could Len not think of that first?

Her brother frowned in a solemn manner, seeming to be in deep thought, then, "I'm sure she'll allow us once I inform her that we'll be in a group of ten or more. We'll be safe by numbers." Why did he look like he really wanted to go?

"You're right." Rin picked up the remote and plopped next to Len who quickly black screened his phone, "So, who was the one to text you?"

Len was relentless to say, and appeared to struggle with the name, "...G-Gumi. Yeah, it was Gumi."

"Oh?" Rin's voice lightened, "Text her back that she's so going down tonight!"

He blanked for a second, then agreed with her, "Yeah, sure."

She had a feeling he was lying to her.

.V.

An hour and a half had passed and the two were getting ready for the night, having already informed their Mother of their activity and gained her acceptance as long as they both had their phones on and answered her calls or texts.

Len was currently in the living room, texting Kaito to stop texting him those ridiculous chain mails.

"Len!" he turned to face Rin who was all dressed up for the night, "I'm gunna go out for, like, ten minutes real quick."

Len made a face, "It's almost time to leave, Rin."

She waved at him with a dull face, "I know silly. But I just got an email that the game I was waiting for has just come out and I have to get it today since I didn't reserve it ahead of time."

Len nibbled on his inner lower lip, "Fine, but be quick. We both know we don't want to be the last ones to arrive."

"Got ya." She put on her shoes, "By the way, Mom's leaving for the store in a couple of minutes, so don't fall asleep yet."

Len rolled his eyes and waved his phone at her, "I'm not going to fall asleep."

"Yeah, and we're not twins." With that, Rin left; her Mother following minutes behind, also telling Len to not fall asleep.

He told her he wouldn't and waved her goodbye. He couldn't possibly fall asleep with the insane amount of texting Kaito was doing. But when 6:20 rolled around, Len's eyelids grew heavy and soon the world became hazing and blurry.

.V.

Slam!

Len was startled from his slumber, jolting up whilst wiping his drool with the back of his hand.

The first thing he did was inspect the place, noticing that his Mother's objects were gone, meaning she hadn't come back yet. Next was the clock, which read ten till seven.

He really did pass out.

Stomp! Stomp! Stomp!

He was halfway at turning toward the hallway but his sister tackled him back onto the sofa with great force, which startled him even more.

"Rin?" Len gently shook his sister's frame above him, taking notice of her stiff body structure, "Hey, something up?"

Rin's tiny hands gripped his collared shirt, her right holding her phone. Slowly, she raised her head up, revealing her pale facial expression; her eyes reading shock and disbelief.

"Rin..." Something wasn't right.

"He-Here he is..." she sniffled into the phone and handed it to Len, her hand shaking.

Len rose his upper half up whilst making sure Rin didn't fall off; he took the phone between his shoulder and ear as his arms wrapped around Rin to ease her shaking body.

"What's u-"

"Fucking shit, Len!" Something was definitely up since Kaito never swore, "Why didn't you answer your fucking phone? That's want it's for, right? Shit!"

"Uh, I fell asleep..."

"Right, right. You fucking fell asleep. Hear that Gakupo, he fell the fuck asleep! Handy, eh?"

"I don't like your attitude Kaito, or your tone of voice," Len started but ceased his warning due to Rin shaking her head. "Look, just tell me what got Rin so shaken up, okay?"

Kaito was silent on the other end, and then he breathed a heavy sigh, "Just... Just come to the meeting place, you'll know once you're here." And he hung up without another word.

Len took the phone away, staring at it in confusion. "Rin," - he gazed down to the tense girl, "do you know what happened?"

She looked like a scared, mute girl; afraid to utter a word if she could.

"Rin, please tell me." Len assured her with his tone, "Please?"

"...news..."

"What?" He felt his heart drop to the pits of his stomach; he must have heard her wrong. "Come again?"

"The news..." she mumbled, mostly to herself, trying to grasp reality, "Killer... the news..."

He had a hint of what had happened, but he really didn't want it to be true. His brain wouldn't allow it to be.

"Come on, Rin. Get up; we got to head over there." He pushed his sister up, her body light but still tense, which only caused him to worry more.

What had shaken his sister?

He helped his sister over to the front door, helped her place her shoes on, her coat and straightened her up. She felt like a doll in his hands.

"Emerald..." Len ignored her then put his own shoes on and walked forward, slamming forehead first into the door.

Normally, the two would laugh their rears off at that, but right now, the action only pissed Len off more.

"Eyes..."

With new found fury, Len ripped the door open, making it slam against the wall, triggering Rin to tighten her hold on his hand.

Her presence made him calm to an extent, and thanks to her, they moved forward, toward the meeting place in throbbing silence.

.V.

"Oh God..." Len muttered under his breath as he watched adults push people back, telling them that everything is under control and that they should all be heading home.

Len pushed his way through the crowd with Rin dogging behind him, one hand held in his and other gripping the tail of his shirt.

He got to a spot that allowed him to search for his friends, but from the corner of his eyes, he saw the victim under the white sheet; her vivid green hair stained with crimson, her eyes no longer present but censored out.

"Gumi..." he whispered out, his head feeling light and his body numb.

Gumi was the victim.

"Len!" The blond snapped back to reality, but numbness was still present.

Kaito, and the rest of the gang, walked up to the blonde twins, their faces looking years older and their body language being that of a witness.

"Ho- How did...?"

"She went ahead, about thirty minutes ago to get the game her and Rin were waiting for," Gakupo answered, his violet eyes dull and lifeless, "I didn't think... I didn't..." He had just lost his sister.

Len clinched his right hand into a fist. That serial killer had murdered in board daylight, yet no one seemed to know until the group had arrived.

"Sorry, Kaito. About earlier..."

"It's fine, I acted without thinking. It's just... you know... this..." he motioned to Gumi's body that lay under a white sheet.

Len then took in the group; how beaten up Gakupo looked, Kaito appearing in disbelief, the girl's looked to be frozen in a nightmare and the rest all in a haze.

None of them wanted to believe that Gumi was just murdered.

"I... I don't think I can face Mom and Dad..." Gakupo croaked while his large hands engulfed his face as his body quivered. Luka wrapped her arms around him and tried to ease him with her hushed words but ended up spilling tears for the both of them.

The group soon followed suit, Miku being the first to burst into a silent sob.

Len's body unconsciously moved toward her, but Rin's fist tightened on his shirt, halting his movement; he stayed put.

He felt too numb to shed tears, though he knew that showed disrespect toward Gakupo. But he was sure the guy understood.

Rin behind him was quivering hysterically, and try as he must, she wouldn't allow him to turn around and embrace her.

Though he didn't feel wetness from her tears as she placed her forehead against his back, he knew she was crying for Gumi. They were the best of friends after all.

A/N: I want to make this clear: These chapters are not glanced at. Meaning: they are written once, and then posted. Granted that my sister reads them first, other than that, they aren't edited. Though you are welcome to inform me of errors and such (like my sister, though she understands how/why I make more than normal mistakes this time around).

The Gang Includes: Len, Piko, Gakupo, Kaito, Yuuma, Rin, Miki, Luka, Meiko, Gumi and Miku.

Soo... Who do you think the killer is? {Don't fall for my trap, gals/guys! It's a very deep hole to crawl out of ;)}

R&R? Pretty please? Feed me your thoughts of this idea, your view point, who you suspect, what you're doing for Halloween… I actually don't expect reviews for some reason, but it's fine since I post for reads over reviews.

Reviews are greatly appreciated and so is constructive criticism!
