Greetings, readers. I bring you a cross over.

Vampire Knight and Death Note, but there will be other crossovers in this story, as well. Naruto, Loveles and Bleach and Higurashi and Umineko... Eventually, I may even add some other crossovers for it, as well.

Disclaimer: I own none of the above animes and mangas. I do own this so called game, 'Supernatural Explosion' because I made that up from the top of my head.

Chapter 1:

Class was boring for Matt. He sat in the back of his maths class playing one of his newest video games. Supernatural Explosion, was its name. He basically ignored the teacher when she was calling out the roll. She learned to live with it and just searched for him. He was always right in the back corner, so it wasn't too hard to find him. The maths teacher, Mrs. Kintook, ticked the name on the list, Mail Jeevas.

"Class." The round teacher stood up from her seat, and walked towards the door. Most of the kids looked in her direction, the others remained talking. "Class!" Mrs. Kintook raised her voice, only to be ignored by Ichigo, Yuuki, Sayori and Naruto. The teacher grabbed a metre long wooden ruler and banged it against the white board. It made a loud bang, and the kids turned their attention to her. Mrs. Kintook smiled at her success. "Today we have a new student, he is standing right outside the door. I expect you all to be kind and pleasant to him." The teacher ordered. "The principle, Chairman Cross, has said that Yuuki and Zero shall show him around, because they are the junior prefects." She said while opening the door.

Yuuki grinned. "A new student? I wonder if it's a boy or a girl." Yori also smiled. She was sitting next to Yuuki in the second row, right next to the wall closest to the door. Zero was sitting directly behind her, with a spare seat right next to him.

The teacher moved out of the door frame to let the newbie in. Matt looked up from his game, and noticed what he thought must be a girl. He wasn't sure, because she had her head kept down. She had shoulder length blonde hair, and a very small frame. She looked flat chested, Matt noticed. The girl was wearing black skinny jeans, and a leather jacket. Even though he couldn't see her face, she seemed pretty good looking.

"Young man," The teacher began, eyeing the new kid. Matts eyes widened in surprise as his face grew bright red. He quickly ducked it before anybody noticed, and began to play his game. "Are you aware of the uniform, here?" Mrs. Kintook asked. The new boy raised his head. He was extremely pale, and had ice blue eyes. He smiled at her. "Yes I am, but you can understand that my family and I have only just moved here. We have not yet had the chance to purchase one." He explained. His voice was completely calm yet you could hear the smile in it. Matt tried to ignore it, even though he wanted to look up at the boy. Zero glared at the blonde haired boy standing in the front of the classroom.

"What was your name, again?" The teacher asked him. "Mihael." He answered. "I prefer Mello, though." The teacher gave a brief nod, not really caring what his nick name was. "There are two spare seats in this class. One next to Zero Kiryuu," The teacher said, pointing at the silver haired boy sitting in the third row on his left. Zero moved his leg up on the spare seat, so Mello could not sit there. "-And one next to Mail Jeevas." Mrs. Kintook pointed to the opposite side of the room at a boy right at the back, his head ducked low like he was hiding something under the table. His black school jacket was undone, and his white button up shirt had two undone buttons, showing off his striped shirt underneath. Matt did not look up at hearing his name.

Yuuki noticed that Zero had put his leg on the chair, and frowned. "Zero, you must be nice to our newcomer! Move your leg!" She shoved at his knee. It did not budge. "Don't worry about it." Mello added. "I'll sit next to Mail." Zero glared at the boy who was dangerously close to him. Yuuki smiled at the blonde. "Ok, but come to me after class, Zero and I will show you around. I promise he'll be nice." She said, grinning. "Won't you, Zero?" Her voice lowered. Zero said nothing. "Just don't worry about him. He's always like that. I don't know how I put up with him!" She giggled. Mello smiled at her, noticing something on her neck. Two purpled dots, like a vampire bite mark. Zero knew that Mello had seen this. His gaze met with the blonde. Zero gave him a very hard, cold stare. Mello returned it, and walked to sit next to the brunette at the back.

He pulled up the chair, and sat down on it. Matt looked up at him, then fell back into his game. "Hi, I'm Mello." He greeted. "Matt." He replied. "But the maths teacher said your name was-" – "I know what she said. Call me Matt." He grunted. Mello nodded, then pulled out an empty gridded book from his bag, and a pen. He boredly tapped the end of it on the table. "So, what are you playing?" He asked. Matt looked up from the game he was hiding under the table. "Supernatural Explosion." He answered. "Whats the object of it?" Mello asked out of curiosity, mostly because of the word 'Supernatural'. "You have to kill monsters like werewolves, and vampires." The brunette replied. Mello raised his eyebrows. "Monsters are those who harm children and animals." He said. "Yeah, vampires and werewolves." Matt laughed quietly. "Touché." Mello barely spoke this word.

"Do you have an interest in supernatural creatures?" Halfway through the lesson, Matt decided to speak. Mello looked up from his work book. "Yeah, I suppose." He answered. Matt smiled. "What are you mainly interested in?" He asked. Mello shrugged. "You know, the usual. Mostly vampires, though." Matt nodded in agreement. "I've been studying these sort of creatures all year." He told the blonde. Mello smirked. "Really?" He asked. Matt nodded. "Call me crazy, but sometimes I believe that their tales aren't that farfetched." Mello's expression was blank. "So you believe vampires are real creature?" He asked. Matt shrugged. "Sorta." He said. Mello leaned in close enough for only Matt to hear was he was about to say. "I do."

By the end of the lesson, Mello noticed that Matt was reading something under his desk. He looked over the boys shoulder. A comic. A comic about vampires. "Vampires again?" He smirked. Matt jolted in surprise. "Oh, sorry. You scared me." He huffed. "And yeah, vampires. Again." He laughed. "This says the best ways to kill one. They say you can put a stake through its heart, but that'll only paralyse it, you can cut its head off and shove garlic in its mouth, or you can throw it out in the sun." He grinned. Mello raised an eyebrow. "The sun won't do a lot." He said. Matt laughed out loud, gaining looks from a few kids. "Are you kidding? Vampires hate the sun! It burns them to ash! Have you never read Bram Stoker's Dracula, or Anne Rice's Interview with the Vampire?" Matts voice was raised in disbelief. "Yes, I have. I believe that the sun just won't do too much damage to the vampire." Mello continued on with his theory. Matt raised his eyebrows. "You've been reading Twilight, haven't you?" He said. "I've read it, but I know that vampires do not sparkle."

Mello turned his head to the side, noticing Zero was staring at him. His eyes were hardened and cold. Mello smirked at him. This seemed to have made Zero even madder.

"Don't worry about him." Matt broke Mello's gaze. "Hm, why?" He asked. "Zero Kiryuu isn't one of the nicest kids. He's hard to warm up to, and glares a lot." He laughed. Mello rested his chin on the palm of his hand. "Why?" Matt shrugged. "I don't know. He's always been like that. But, I think the nicest kids in this class are Naruto, Yuuki, and Orihime. Ichigo is also nice, but he's a bit of a perverted dick head." He laughed. "I don't really know about Rukia. She was the new kid before you were. It seemed that Ichigo and her already seemed to have known each other." The boy shrugged. Mello nodded, taking in the information.

15 minutes later, the bell rang. Matt stood up, shoving his comic back in his bag. Mello also stood, noticing that Yuuki was waving to him by the door and holding onto Zero's sleeve. The silver haired boy was frowning, and his eyes were darted to the side. He looked like he wanted to leave. "Nice meeting you." The blonde said. Matt nodded. "I have to go with Yuuki and Zero." He said, and left.

"So," Yuuki began. Mello's head lifted up to see the taller girl. "Have you made any friends yet?" She asked. The blonde shrugged. "I can't say that I have. I barely know anybody. I can say I've made some acquaintances, though." He answered. Yuuki smiled. "Like who?" Mello smiled. "Mail and yourself." He did not add Zero, which made him want to laugh out loud but he refrained from doing so. Yuuki giggled, and Zero just didn't care. He had mutual feelings for the blonde. Dislike. The silver haired teen had his reasons why, the moment he laid eyes on him.

"Do you have any family, here?" Yuuki asked. "Yes." Mello answered. Zero's eyes shifted to the blonde that was walking next to Yuuki. "Who might they be?" The girl gave a childish smile. "I have a cousin here, L Lawliet." The blonde brushed his hands down his leather jacket, trying to smooth it out a bit. Yuuki's smile slightly faded. Zero's frown remained intact. "Do you know them?" Asked Mello. "Yes." Zero finally said something. His voice was cold, and snappy. Yuuki gave him a tiny smile. She was glad he finally said something, even if it was intentionally rude. Mello did not look at Zero. He kept his eyes trained in front of him.

"Did you know that your cousin is a homosexual?" The silver haired boy asked. Mello still did not turn his head. "Yes. I believe his boyfriend is Beyond Birthday." The blonde turned his head slightly to see Yuuki's and Zero's reaction. Yuuki was keeping her head low, and Zero was staring right back at him. Mello gave a smile. It wasn't exactly a kind sort of smile. It was mysterious, but Zero understood this boy's situation. He was not stupid. "So are you." He stated. Mello raised an eyebrow. "Excuse me?" Mello knew. "You are homo." Yuuki looked up, and punched her friend in the stomach. It didn't hurt him. He grabbed her fist, which was already by her side . "Don't do that again, Yuuki." He growled. "That was extremely rude of you, Zero Kiryuu! Who do you think you are!" She snapped. Zero said nothing, his head turned away from her, and he tried to tune out what she was saying. "How dare you! You have no right to judge people so quickly!" She punched his arm. Zero turned his head back around, with a glare painted on. "Yuuki! I told you not to do that again!" He grabbed her shoulders, and gave her a shake. Yuuki's eyes widened at the aggression. Zero stopped shaking her, realising he was a hypocrite for what he had just done. "I'm sorry, Yuuki." He pushed her away from him. Yuuki was still in shock.

Meanwhile:

Matt walked by the least crowded place in the entire academy. Only a few kids hung out in this area, the Otakus mainly, but there were some other kids as well. The nerds, Matt, and the game freaks, Matt again.

The brunette looked up from his game. He was growing bored of it. He had already beaten it once. L and Beyond were sitting just up ahead of him. L was always sitting in his boyfriends lap. That's right, they had already come out of the closet. L was a bit nervous, but he trusted that BB would make it roll easily with people when they found out. Matt honestly didn't care who was gay, or not. Kiyomi Takada did, though. She was like the biggest gossip girl within the whole academy. She and Misa Amane were always hanging off Light Yagami's arms. Matt felt sorry for him though, because the girls were horribly annoying. If they were quieter, and if Kiyomi were a bit more 'attractive', Matt would have been jealous of the senior. He already didn't much like him, though. The older boy always made him feel uncomfortable, and Light was usually just a little narcissistic. Although, Matt would never, ever admit this out loud, he found Light Yagami, attractive. Well, his Facebook picture at least. Matt still had a small thread of his straight sexuality, he hoped.

As usual, L was sitting on Beyond's lap again. His head was tilted, exposing his pale white neck, and his expression was blank. Beyond was smirking while caressing his boyfriend's throat with two of his fingers. They both kept their eyes trained on the brunette as he walked by. Matt ducked his head down, and began to play his game again.

The two dark haired teens watched as Matt walked by. "What was he looking at?" B grumbled. "Maybe he was jealous." L replied. "Well, he can't have you, because you are mine. This mark proves it." Beyond pulled down the collar to L's school shirt and revealed an old scar. Two healed over holes, very much so like a bite of a vampire. The scar still felt sensitive to L, and B knew it. He leant over and let his tongue slowly stoke the old wound. L let out a low moan. It felt so nice to him. B very much liked getting a reaction from him, especially one that sounded longing and needing. L slowly turned his head and faced his emo-ish looking boy friend. B was grinning, showing off his long fangs that will forever be there. The young detective rested his head on the shoulder of the one he loved. Beyond sneaked his hand underneath the younger teen's jacket, and began to unbutton his shirt. L didn't care; he stopped caring a long time ago. B always did this. He was such a sex crazed demon. The only thing that ever seemed to effectively stop B from doing this was when they were separated.

The red eyed vampire gently kissed down the other boy's neck, until he reached down to the collar bone. He looked back up, making sure that no teacher was around, thankfully there were none. He carefully shifted L into the centre of his lap. L felt a growing bulge inside of B's pants. He didn't mind, because it was happening to him as well. Beyond gently stroked L's bulge through the material of his black school pants, gaining another moan from him. L's finger nails began to dig into the back of his boyfriend's neck. His forefinger and middle finger rubbed up against it, collecting friction. L clenched his eyes shut, and his teeth together. This felt so good to him, yet so bad. He and B had only done this a few times in public, and they had never been caught, but there is always a first time for everything.

B suddenly stopped rubbing L's straining erection. The younger male exhaled, and opened his eyes. B was watching as Yuuki, Zero, and Mello walked past. L rolled off his boyfriends lap, and collapsed on his back, completely forgetting that his shirt was undone. Each side of the shirt had fallen off his body, showing off his delicious torso. His chest was rising up and down, his nipples were erect, and so was his manhood, which was an obvious bulge. He was glad that Mello had not come over to where they were. That would defiantly be an awkward encounter.

"We are going to the bathroom, now!" Beyond demanded. L had finally caught his breath, even though he didn't really need it. "Huh?" He asked. B stood up, and grabbed his boyfriends arm. "Let's go." He dragged L into the direction of the boys toilets. L and B still did not remember about the undone shirt.

When they got in there, Beyond threw his younger boyfriend into one of the empty stall, and slammed, and locked the door behind him after he entered. L was sitting on the seat, his eyes were wide, and his chest was heaving. "Sex, now!" The red eyed vampire commanded. "What! Now!" L huffed. "Yes! Now!"

L quickly undid the button on his pants, and B pulled them down for him. The younger vampire swiftly pulled down his boxers, and B did the same. After they had no clothing on, they didn't want to waste too much time. "All we need is some sort of lubricant; I'm not really in the mood for pain." L sighed. "Saliva?" B suggested. "Who's saliva?" L replied. "Yours." L frowned, and then eyed his straining and neglected erection. "Fine." He answered, standing up off the seat of the toilet. Beyond stood against the wall, and L bent down. His pale hand clutched the base. L opened his mouth widely, and darted his tongue out. He carefully licked the head, making sure it was coated in enough saliva for it not to hurt him, because whenever the two have sex, Beyond takes him roughly.

The young detective heard a small gasp of pleasure from the one towering above him. L delicately licked the underside of it. B's hands gripped into L's hair, and clenched his fists. L ignored the pain. He gave the underside one more lick before taking the whole thing in his mouth. Beyond let out a groan of satisfaction.

L pulled his mouth away, and looked up at Beyond. His whole face was bright red. He was staring right back at the younger male. L stood up. He was only a little bit shorter than Beyond. Only by 3 centimetres. Beyond pushed L to the opposite wall. Their erections were pushed up against one another. "You ready?" BB asked, his voice was low and husky. He didn't give L a chance to reply, because his hands travelled low, and separated L's ass cheeks before pushing himself in. L made a loud groan, and clenched his teeth. He could feel Beyond inside him. He felt like an intruder. L was glad he did a fairly thorough job with coating him, otherwise it would have hurt much more than it already did. He felt as if he were stretching, and stretching hurt. Beyond only gave him two seconds to recover before he started moving his hips back and forth. His hands were planted either side of L's head. The younger male's quick breaths were slowing down. Beyond slowly pulled himself out, before pounding back in. The aggression no longer surprised L. He was used to Beyond pounding into him.

Beyond repeated this action. Pull, pound, pull, pound, pull, pound. L's moans were becoming louder. His mouth had to be covered up with his boyfriend's hand. BB slowed his actions down. His hips gently rocked in circular motions. L just didn't feel that the slowness was enough. Beyond wasn't even that far inside of him. L wanted to feel warm inside, and not that fluffy feeling you have when you do something kind for someone else, he wanted hot, sticky, burning, searing, scorching, heat inside of him. He grabbed the slowly rocking hips in front of him, and pulled them closer. L moaned in satisfaction as he felt a mass slide up to his prostate gland. "Oh, L!" Beyond gasped. "You sure are enthusiastic today!" L made a weak grin, as his eyelids were falling. "You feel... So good." L huffed. Beyond started pounding into him again. He felt his length begin to ache at all the labour he forced it to do. He didn't care. He smashed himself into L over and over again. L's eyes widened in pain as the saliva that was used as lube wore off. It felt like fire was ripping inside of his passage. Beyond kept slamming into him over and over again. L's moans became groans, the groans grew louder, and louder.

At how much enjoyment L was getting from his manhood rubbing against B's stomach, he came all over the two of them. Beyond stopped caring about how much noise they were making. He kept gasping, and moaning at the pleasure he was receiving from this. L obviously did the same. Beyond felt a growing tightness and he knew he was finally going to climax. He kept pounding into L, harder and harder. L was too huffed to say anything. He was in too much pain to do anything. He tried to remain still and his boyfriend pounded and slammed into him.

Beyond knew all he needed was one last thrust. Slam! And he came. He let out an extremely long gasp, and pulled himself out. The older male fell back, and sat on the lid of the toilet seat. His eyes were closed, his face was bright red, and he was covered in sweat. He remained there as L slid onto the floor, and gasped for air. He ignored the soreness from his ass as he sat.

After at least ten minutes recovery, the two stood up very slowly. L saw that his shirt was still undone, and his toned abdomen was covered in his own seed. Beyond saw that his school shirt had a wet patch on it. He knew that it was L's climaxing that caused it. 'That's what you get for leaving your shirt on, when you are about to have sex.' He thought, pulling his pants back up. L had already dressed himself, and watched as Beyond was trying to do up his black day class jacket to cover up the spot so nobody would ever notice it.

Beyond opened up the cubicle door. Keiichi Maebara, and Battler Ushiromiya were standing right outside. It was obvious that the two knew what was going on in there. They had cheeky grins planted on their faces. When they saw Beyond, they exchanged glanced. "I'm disappointed." Battler frowned. Keiichi nodded. "So am I." He said just as L had walked out. Keiichi and Battler also knew about Beyond and L's situation. "I was hoping it was some hot chick in there! You know, we could have seen some good boobs!" The brunette sighed. Battler patted his friends shoulder. "I know, some hot chick with really huge tits!" The two perverted teens almost drooled at the image they were getting in their heads.

Beyond was scowling at them. L didn't seem to care, he was too busy worrying about how sore his ass was. "What are you two doing?" The red eyed vampire snapped. Battler and Keiichi went red in the face. "Oh, we weren't imagining it was some hot chick in there, with the biggest tits you've ever seen! I swear!" Battler lied. Terribly. Keiichi face palmed. "You are a really bad liar, you know that!" He cursed. Battler made an awkward laugh as he saw BB clench his fists. Both of the year nine teens knew they were about to get bashed by a senior- a gay senior, at that.

Before Beyond could slam a fist, Battler and Keiichi made a run for it.

Ok, so that was the first chapter of my major cross over! I've thought that I'm going to make all good pairings from all of the anime's I've jammed in here have sex, so that means there will be LOTS of lemons in this story! X3

So, please review because it'll make me happy and not want to send a vampire onto your tails! X3
