Rosario + Nephilim

Tsukune Aono, Age 15, Hobby/Specialty Demon Slaying.

"Man, I'm an apprentice demon hunter, why do I have to go a school for monsters?" said Tsukune as he rode the bus to YokaiAcademy. The bus was empty except for him and the bus driver, and he was bored out of his mind. A few times, he drifted into sleep and had several dreams of Trish, Lady, and Lucia before snapping himself awake and berating himself for thinking about Dante's women.

"…You are…" the bus driver said, catching Tsukune's attention, "the student enrolling at Yokai Academy?" he finished. "Is there any other reason I'd on this ghost town of a bus?" Tsukune replied. "In that case you had best prepare yourself now…" the bus driver said with a creepy smile, "HEHEHE When we come out of this LONG tunnel, we'll be right in front of the school, HEHEHE Yokai Academy is a VERY HORRIFYING SCHOOL!" Tsukune smirked, "Really, well that sounds like my kind of party."

Chapter 1: Vampire and a Nephilim

Tsukune got off the bus and stared at the academy wondering how many hot girls there might be. As he was about to walk to the academy, he heard a panicked "LOOK OUT!" and turned around and saw a girl on a bike about to crash into him. He sidestepped out of the way, pulled off her bike before it crash, and held her bridal style.

"Are you O…k?" he faltered when he saw her face. She had a heart-shaped face, emerald green eyes, delicate lips and long pink hair. She was by far the most beautiful girl he had ever seen in his life. She looked at him with slight blush on her face, which only served to enhance her beauty. 'Damn if all the girls at this school are this beautiful then I am never going home.' Tsukune thought to himself.

Inside Tsukune's head there was a tiny devil telling him to bed her now while he had the chance. At the same time, an angel was telling him not to listen to the devil and that he should not try to bed her or any girl without their consent. The devil in his head began to show images of him embracing this girl in the nude as she moaned in pleasure. Such images had caused a brain overload and his nose began to bleed.

"Oh you're bleeding!" the girl said, snapping him back to reality as she reached into her school coat pocket to for a handkerchief. She tried to wipe it of for him but then she appeared to be dizzy. "The scent of…blood," she said her eyes half closed, "I…I…can't," she then clutched his arms, "I lose control when ever I smell that scent," she said, with her head on his chest. "I…I'm sorry but…" she said as she brought her hands up to his face, "it's just because…"

"I'm a vampire," she said finally as she sunk her fangs into his neck. The sensation that spread throughout Tsukune's body was like nothing he had ever felt before as he felt the blood drawn from his neck. Inside his head, the devil was screaming at him to take this girl now while the angel was trying to keep him in check.

Meanwhile the vampire was savoring the taste of his blood. It was the first time she had ever drunk blood directly from a living creature and it was far superior to the blood packs she had. His blood tasted like a strange intoxicating mix of cold, sweet, sour and spicy. She then realized what she was doing and removed her fangs from his neck.

"I'm terribly sorry," she quickly apologized, "I shouldn't have done that without asking." Tsukune chuckled as he let her stand on her own, "It's okay," he said, "I mean you are a vampire right?" She placed her hands on her cheeks as a blush appeared on her face and she closed her eyes, "Yes, I am, and I have to say, your blood is very delicious."

"Thank you Miss…" Tsukune said, as he wordlessly asked for her name. "Oh, I'm sorry, my name is Moka Akashiya." she introduced herself. Moka then looked at him nervously, "D-do you hate vampires?" she asked. "Why should I?" Tsukune replied with a question of his own, "They've never given me a reason to hate them." Moka smiled in appreciation, "That's great, then if you're okay with me, please my friend. I don't know anyone here and it was starting to feel a little lonely."

Tsukune smiled, "Of course, from now on you've got a friend in I, Tsukune Aono, at your service." he finished as he struck a Piros the Third pose. Moka giggled at him before picking up her bike and walking alongside him towards the school. "I'm very pleased to meet you Tsukune. When the entrance ceremony is over please talk to me some more ok?" she asked in a slight affectionate tone. "Sure thing Moka," Tsukune replied.

-In Class-

The students all sat in their desk as their teacher walked in. The teacher was a carefree looking woman with blonde hair that seemed to stick out at the top to look like cat ears. She wore oval glasses, though why she would be wearing them was a mystery to Tsukune as her eyes were closed as she walked in. She was wearing an open white blouse, over an orange shirt with a brown skirt and low heel sandals. She walked to her stand and introduced herself.

"Hello everyone and welcome to YokaiAcademy! I am your homeroom teacher Shizuka Nekonome," she said cheerfully. "I'm pretty sure you all already know this but, YokaiAcademy is a school of monsters, by monsters and for monsters!" If Tsukune were human, he would have been stunned by this revelation and would probably have had an anxiety attack.

"The earth has already come under the come under the control of humans," Shizuka continued, "In order for us monsters to continue to survive; we have no choice but to continue to peacefully coexist with humans. At this academy, you will be studying 'How to Coexist with Humans'! Therefore, for that reason as a school rule, YOU ARE NOT ALLOWED TO REVEAL YOUR TRUE FORM! Understand?"

"Hey Teach," said the guy in the desk next to Tsukune's, "Wouldn't it be better to just eat those stupid humans? And in the case of hot girls, better to have some playtime with them?" Tsukune instantly didn't like this guy as the angel and devil in his head told him to gut this guy before he caused any trouble.

"Well," Shizuka Nekonome said, "here at YokaiAcademy, everyone is a monster; there are no real humans around here. This academy is within a secret world created by the Headmaster. Any humans who came in would probably be executed." Tsukune thought about this and decided to ask the question that was on his mind. "Wouldn't that defeat the purpose of this school, to learn to coexist with humans? I don't know about the rest of you but I find it hard to coexist with somebody I killed."

Shizuka thought for a second, "Well, you make a good point, but seeing how a human has never crossed the threshold of the school, I can't say whether or not it would." She answered the question, intrigued by this new student. In all the years she had been at this school, she had never thought that this school might itself be a contradiction of its purpose. While she was pondering this notion, the door slid open and pink haired girl came in.

"Sorry I'm late," she apologized, "After the entrance ceremony I kinda got lost." Shizuka smiled at the girl as she resisted the urge to scream "KAWAII" and she said "That's okay, just find a seat somewhere." When she walked in, Tsukune got a look at her face and saw that it was Moka. Tsukune wasn't the only one to notice Moka, in fact, nearly all of the male students (and a few female students) had hearts in their eyes and ideas about asking this girl out on a date instantly filled their heads.

"Hey Moka," Tsukune said casually as she neared his desk "Huh?" Moka said as turned in the direction of the voice. "Tsukune?" she said in surprise, then she hugged him exclaiming, "Tsukune! We're in the same class!" Instantly half of the class stood up in outrage. "Hold up, who the fuck is this guy?! What's his relation to that hot girl?!"

-After Class-

Tsukune was walking with Moka down the hall. As they walk around Tsukune could feel the envy of the male students they passed by as they unleashed their killing intent on him, but he ignored it since if any of them tried anything he would make them regret it. As they continued to walk down the hallway, another student stopped them, looking at Moka.

"You're Moka Akashiya, right?" he said, "I am your classmate Saizo Komiya! Nice to meet you." The devil in Tsukune's head began to hurl curses at the thug, while the angel was reminding him to show restraint. "By the way," Saizo said as he lifted Tsukune by the coat, "What's a beautiful lady like you doing associating with trash like this guy?" Tsukune glared at him for a second, remembering where he saw this guy; he was the one in their class who ask why they couldn't just eat humans.

Tsukune could hear the whispers from the onlookers, and based on the rumors they were whispering to each other, Tsukune's dislike of Saizo grew even deeper. "Um excuse me, Saizo was it," Tsukune said, "Could you put me down before I have to bust your jaw?" Saizo looked glared at Tsukune, "Sure I'll put you down," and he tried to throw Tsukune across the hall.

Tried being the keyword in that sentence, as Tsukune left Saizo's grip he spun in midair, pulled out a sword, and pointed it at Saizo as a blue aura surrounded the blade. The blade morphed into a clawed chain that flew towards Saizo and grabbed him. Tsukune was pulled towards Saizo and when he was close enough, he delivered an uppercut that sent Saizo flying.

"Tsukune!" Moka said as she put her arms around him, "Are you okay?" Tsukune just smiled and hugged her back. "Don't worry about me; I was just looking for an excuse to deck that guy." He then let go, "Come on, we haven't finished checking out the campus." Before they were out of earshot Tsukune heard the students gossiping, "What just happened?" "Was that a sword he was holding?" "Where did it come from?" "Why did it change into a chain?"

They continued to explore the campus until they came to the school dorm, a school dorm in the middle of a graveyard, with dead trees, and a gloomy sky. All that was missing was the strike of lightning. "Oh Tsukune what kind of monster are you?" Moka asked him. "Moka you missed most of the lecture so you probably didn't get the part about not revealing our monster identities." Moka gasped, "I'm sorry, I shouldn't have asked that you." Tsukune waved off her apology, "Don't be sorry, I was just telling you so you don't get in trouble. As far as I'm concerned, it's a stupid rule. I mean what if a human had accidently enrolled in this school. Nobody would know unless he told them."

Moka thought about what he said and the idea of humans in the school scared her a little. Her thoughts were interrupted when she heard Tsukune's voice again. "But it's kinda unfair that I know your monster identity and you don't know mine, don't you think?" Moka looked at him, saw the playful smile on his face and blushed. "Y-yes, it's not fair." Moka hastily agreed. Tsukune noticed the blush on her face and couldn't help but chuckle at how cute she was.

"Nephilim," said Tsukune. "Huh?" Moka asked in confusion. "It's what I am," Tsukune continued, "a Nephilim." Moka thought for a second trying to remember what kind of monster a Nephilim was. She recalled looking in one of her mothers old books and seeing the term Nephilim. The book did not go into a lot of detail, but it did say that a Nephilim was one of the only beings feared by even the demon lords. "So you're a really powerful monster?" Moka asked.

"What about you Moka?" Tsukune asked, ignoring her question, "I heard that vampires were among the strongest of monsters." Moka blushed again before answering, "Yes, though right now my power is sealed, when I take this rosary off, I become a real, scary vampire." Tsukune looked at the rosary; it appeared to be made of silver with a red jewel in the middle. "But even with our power sealed, we still need blood." Tsukune, already seeing where this was going, decided to let her at it, and the pleasurable feeling of vampire fangs plunging into his neck, returned just as strong.

-Next Day-

Tsukune was on his way to school wondering what he and Moka were going to do after school. "Hey Aono," he heard a voice and turned to see Saizo walking towards him. "It looks like you had a lot of fun with Moka Akashiya after nearly breaking my jaw, yesterday, and you're gonna pay for it today."

"If you don't want to get busted up, you shouldn't just attack somebody at random." Tsukune said as he glared at Saizo. "Your disguise is pretty solid," said Saizo, "What's your true form?" Tsukune shrugged, "Who knows, I'm not even sure myself."

Saizo growled in anger and punched the wall, shattering it. "You don't even know? Don't give me that bullshit! Maybe you're just a puny human; in any case don't go near Akashiya again. If I see you look at her I'll kill you." Tsukune smirked, "You talk big, but can you back it up?" he said, knowing that he could take this guy on.

Saizo walked away growling and Tsukune dusted his coat off. As he continued to head for class, Moka came running to him and threw her arms around him. "Good Morning Tsukune," she said cheerfully. "Hey Moka," Tsukune said, "How are you this morning?"

"I'm doing great," she replied, "Hey Tsukune; I noticed that you seem more comfortable acting as a human than anyone else at this school," it was true; everyone seemed to have trouble keeping their human forms, even the teachers. Ms. Nekonome's tail appeared towards the end of class yesterday, and the poor kid who pointed it out got his face clawed. Moka didn't have much of a problem keeping her human form, but that was due to her powers being sealed. Tsukune was one of the only people who had no transformation problems.

"That's mostly due to the fact that a Nephilim can't use their transforming abilities, until they go through an awakening which can only be done during a life or death situation," Tsukune explained, "I haven't gone through my awakening yet and besides our true forms are rarely that different from our human forms." He allowed this to sink in before he continued, "Also, up until about five years ago I thought I was human."

Moka looked at him as if he had just said he likes to wear women's clothes. "My parents decided not to tell me until I was old enough to handle it," Tsukune continued, "When I found out I wasn't human, I felt like a freak and I started to distance myself from my friends, scared that they'd hate me if they found out what I was." Moka could sympathize with him; she had felt the same at every school she had gone to up until now.

"I hate humans," Moka said finally. "What?" Tsukune replied. "I hate humans," Moka repeated, "All my life, I been going to human schools and I was alone from the start of it." Moka recalled those days vividly, she couldn't fit in with humans, she was so lonely, that's why she came here, to get away from it all. "But then I met you," Moka said, "You accepted me even though you knew I was a vampire, you were lonely too and you hate humans t—"

"Hold up," Tsukune interrupted her, "I never said 'I hate humans', I said I was scared that they'd hate me if they found out what I was, and that was the biggest mistake I ever made." Moka took a step back, hearing the rising anger in his voice. "My friends didn't care if I was human or monster, in fact when it got out that I wasn't human and everybody started to keep their distance, my friends stuck by me without fear, and I'll always be grateful for that. Don't ever assume that I hate humans, it's only because of them that I made it this far."

Moka was taken aback by how he talked about his friends, and she felt ashamed of herself for assuming he hated humans. "I'm s-sorry Tsukune." Tsukune saw tears in her eyes and his anger was replaced with shock. "I-I didn't m-mean to offend y-you," Moka sobbed as the tears streamed down her face, "I'M SORRY!" she said one last time before she turned and ran from him as fast as could.

"Aw shit!" Tsukune said and he started to chase her but before he could make four feet, a pack of Hell Prides appeared before him with their scythes ready for battle. "What the fuck—?!" Tsukune said in anger, "I don't have time for you guys!" Tsukune drew his sword and rushed into battle determined to finish the fight as soon as possible and find Moka.

Moka was standing at the bus stop, holding her suitcase and waiting for the bus. It had been easy to repack her belongings since she didn't finish unpacking. She stood there waiting, all the while remembering the angry look on Tsukune's face. She had made a friend here at YokaiAcademy, her very first friend, and she blew it because of her hatred for humans. She couldn't stay at YokaiAcademy. She couldn't stay with him. It would be too painful.

"Hey babe!" she heard a sudden voice behind her and turned to see Saizo Komiya, "What's a pretty little thing like you doing out here alone?" He grabbed her by the wrist and wrapped his arm around her, "You shouldn't be out hear feeling lonely Moka Akashiya not when you can be with a man like me." Saizo said while licking his lips.

Tsukune had just killed the last of the Hell Prides and continued to search for Moka. 'Moka, where are you?' He had almost given up hope of finding her when he heard a scream, recognizing the voice as Moka's, "Moka!" Tsukune exclaimed, "Hang on, I'll be right there."

"AAAIIIEEE!" Moka screamed as she escaped from Saizo's grip and backed away from him. "Ooh! I'm excited now!" Saizo said as he took his school coat off, "Your beauty surpasses all of the human women I've taken! I've got to have you, Moka Akashiya!" he said as his voice became demonic. His uniform began to rip apart as he grew in size. His muscles bulged out and his height increased to about seven to eight feet. His tongue elongated and thick saliva dripping from it.

"I can't stay in my human form, when I feel like this," Saizo said, "When I come to this point; there is no stopping me… I just can't stay in human form anymore!" Moka backed away from in terror, "No, s-stay away!" she screamed. Saizo just laughed as he approached her, "I'm going to enjoy this little violation!" Moka backed away and screamed, "TSUKUNE!"

Instantly, Tsukune appeared out of nowhere dropkicked Saizo. "Your knight in shiny armor is here!" said Tsukune, then groaned to himself, "God I can't believe just said that." "Tsukune!" Moka exclaimed as she ran to him and held on to him.

"Tsukune, I'm sorry. I shouldn't have assumed you hated humans. To tell you the truth I don't really hate humans, because I'm a vampire, I drain the blood of humans and just end up hurting humans. The whole time I just felt like I wanted to make a friend, even if it was just at a human school."

Tsukune listened to her and felt ashamed of himself for letting his anger get the better of him. "No Moka," Tsukune said, "I wasn't angry at you Moka, I was really angry at myself." Moka looked at him in confusion before he continued, "I was angry at myself for pushing my friends away, I told you that I was afraid my friends would leave me if they found out I wasn't human, and I felt guilty, especially after they stayed with me when everyone else began to hate me. It's something I've always regretted and I still haven't gotten over it."

Moka's eyes began to water as she listened to Tsukune and she looked down, thinking about what her life would be like if she had even one friend like the ones Tsukune described. "So don't think for a second that this means our friendship is over, Moka." Moka looked up in surprise, "You're my friend Moka and there is no way I'll just abandon you, I'll be there for you till the very end."

Moka smiled tears still streaming down her face, as a strange warm feeling sprung up in her breasts. "Aw, isn't that sweet," a voice behind them said and they turned to see Saizo walking towards them, "but, I'm going to have to breakup this touching moment, I've got beautiful woman to rape and a spineless, pencil neck to break."

Tsukune pulled out his sword and gripped it tightly, "You know it pisses me off when a man brags about how he's going to rape a girl," Tsukune said, his voice dropping to a dangerously calm tone, "IT INFURIATES ME WHEN SAID GIRL IS MY FRIEND!" Tsukune roared, as the sword he was holding morphed into a large battle-axe, coated in a red aura. He rushed at Saizo, jumped into the air, and swung downward with the axe, sending the blade flying at Saizo.

Saizo dodged the blade only to run into a right cross. He staggered and felt an uppercut knock him into the air. While he was in the air, he felt something tiny yet painful, hit him repeatedly preventing him from falling.

Moka watched in amazement at how brutal Tsukune was beating Saizo. She was not a big fan of violence, but she could tell that his fighting capability was equal to that of a vampire's. The strange weapons he wielded were also puzzling to her. What kind of ammo were those guns firing, if they could keep Saizo suspended in the air. The sword that morphed into an axe and then into a pair of gauntlets, was also very strange, where did Tsukune get such a weapon?

Tsukune stopped shooting his guns to let Saizo fall and when Saizo was close enough to him, he morphed is sword into a scythe and quickly spun it upwards, dealing multiple strikes to Saizo in a second. When Saizo got back to his feet, he tried to hit Tsukune, but missed as Tsukune back flipped out of the way, before disappearing is a blue flash and reappearing behind Saizo.

His sword became a pair of shuriken, and he threw at Saizo. Each time the shuriken hit Saizo; they multiplied and continually hit struck Saizo before two of them flew back to Tsukune changing back in to a sword. Saizo realizing that he doesn't stand a chance against Tsukune, decided that he'll get to him by killing Moka, and rushed at her at full speed. Tsukune seeing where he was going tried to stop him but realized he would make it in time. Then he noticed a faint red glow from Moka's breasts and remembered the rosary, hanging from Moka's choker that keeps her powers sealed.

He knew it was a gamble but he didn't have time to dwell on it, so he morphed his sword into a grappler-chain and a launched it at the rosary and yanked it off. Instantly Moka began to glow pink, as the ocean turned purple, and the sky turned a reddish-black. A reddish-pink, full moon appeared in the sky and a swarm of bats flew from it and surrounded Moka.

When the bats flew away and Moka was just standing there, Tsukune barely recognized her. Her long pink hair had turned silver-white; her emerald green eyes were now blood red with slit like pupils. Her breasts that were bordering C-cup had grown into a healthy D-cup; her butt had also grown a little. Her entire posture was different as well, where as earlier she mostly held herself timidly, now she stood proud and tall with her right hand on her hip. Gone was the kind, shy and cute girl. In her place was a tough, sexy, and dominating vampire.

"No way," said Saizo in disbelief, "Red eyes, silver hair, and an intense supernatural energy, this is…this is an S-Class monster, a vampire!?" Moka smirked at him before speaking in a low seductive voice, "What's the matter big fella? I thought you wanted me. Just take me…if you can." Saizo stood there thinking aloud, "If word gets out that I defeated a vampire I'll be the king of Yokai Academy." He charged at Moka with the full attention of beating her and making her is sex slave. He tried to grab her, but she stopped him by grabbing his finger. "Do you really think you can defeat me with this level of power?" she said in a bored voice, "Filth like you should know your place!" she said as she kicked him in the face, sending him flying eight feet into the air before he started to fall. Tsukune got into position and readied his guns, charging his energy into them. "JACKPOT!" he yelled as he fired two spiraling streams of energy at Saizo, sending him flying off the cliff.

Moka walked over to Tsukune, looking at him with a strange look in her eyes. "I guess you want this back?" Tsukune said casually, as he held out the rosary. She took the rosary, and looked at him, "You're an interesting one, Tsukune Aono," she said as she stared at him, "Most would be too afraid to intentionally unseal a vampire." Tsukune shrugged, "I guess I was just wanted to see if the legends were true." Moka eyes narrowed slightly, "And your combat ability is on par with my own, I'd challenge you to a spar if I wasn't so drowsy from the seal." Tsukune smirked before responding, "Well, I have my masters to thank for that." Moka leaned in closer, tracing her finger around Tsukune's chin, "And your blood is absolutely luscious." Tsukune just continue to smirk, "Thank you."

She took the rosary and placed it back on her choker, "Well I've got to go now," she said as the rosary began to seal her again, "Watch after the other Moka while I'm gone." When the seal was finished, Moka was had passed out and Tsukune caught her. "Well, we'd better get back and explain why we're so late," Tsukune said as he carried her bridal style, back to the school, Moka unconsciously snuggling into him all the while.

-Next Morning-

"Good Morning Tsukune!" Moka greeted as she ran to meet Tsukune. "Good Morning Moka," Tsukune replied. A light blush spread Moka's face, "Oh my," she said, "When I'm near you my heart just pounds so hard," she said, her blush darkening, "I just want to suck your blood so much!" Tsukune chuckled before loosening his necktie and pulling down his shirt collar, exposing his neck. "Here you go," he said simply. Moka was ecstatic, as she threw her arms around him, "Oh, Thank You, Tsukune!" she said happily before she bit into his neck, "Capu-Chu!"

So whaddya think? Do you like it, do you hate it? Do you have any questions? Let me know in your reviews! Happy New Years!
