A/N: Hello guys and gals, this is TrixBella. This is my first fan fiction that I've thought up while I was reminiscing about R+V and Bakemonogatari and decided to write a slight crossover between the two. Now in this FF, Koyomi Araragi is slightly OOC, replacing Tsukune Aono as the main character, and this storyline is AU seeing as how it's a crossover. I'll try to follow the canon storyline of R+V as close as possible but there will be a lot of non-canon moments as well. I hope you guys enjoy this story as much as I enjoy what I have got brewing in my head right now.

Prologue:

Koyomi Araragi, age 16, was seated at a local bus stop waiting for a school bus that is supposed to take him to his new academy. Fair skin, with medium length black hair, accompanied with an ahoge*, that covered his left gray and blue eye, dressed in a white button up with a green shirt under, black pants and gray shoes, he sat there for 30 minutes waiting for the bus to arrive, pondering what his school will look like and asked himself how he got enrolled there in the first place.

-Flashback-

A wandering Koyomi Araragi was spotted by a certain Oshino Meme, "Oy! Araragi-kun!" he shouted at the startled young man. Koyomi turns and sees the middle aged "aloha guy" walking towards him, waving quite energetically. His upside down cross necklace waving side to side as he walks, his steps forming a 'clack clack' with his sandals that make him look taller than he seems, bearded (though it's really a small goatee) face forming an ear to ear grin, spiky blond hair waving around due to the conveniently placed breeze.

"Ah, it's you. You spooked me there for a second," Koyomi sighed

"What's up? Why do you have a grin that looks oddly like a certain Cheshire cat on your face?" he asked, eyes narrowing at the suspicious person as Oshino places a hand on the young man's shoulders and stares back.

"Calm down. No need to be so alert around me, Araragi-kun. No need to stare at me. You are really energetic, did something good happen?" still keeping the grin on his face, he continued, "I've just come to tell you some good news! But first, let's go sit down somewhere, preferably a place with comfy chairs and good coffee."

The young vampire's glare fading, he walked on ahead, the middle aged priest following suite "You just want me to buy the coffee for you," Koyomi mutters under his breath "Let's go to that place then and see what you have to say." He pointed at the nearby coffee shop.

-A nearby Starbucks-

They arrived at the store and instantly found it was warmer inside. Koyomi surveyed the place; tan and green were the colors of the entire cafe, soft looking couches placed on top of a circular rug in the corner with a table in the middle. Smooth jazz reverberated throughout the area. Overall, it created a mellow atmosphere that's perfect for conversation. That and coffee. A small female medium haired brunette took both Koyomi and Oshino's orders, the girl stealing glances at the former and winking at him. Koyomi shrugged it off as a teasing behaviour. Once they got their orders, both men sat down in the comfortable couches.

Koyomi is seated across the middle aged priest, the vampire holding a cup of coffee, and the priest holding an espresso cup. Both sit in silence for a few minutes until the young vampire breaks it by asking the question of the day,

"So? What is this good news you have to tell me?"

Oshino stops drinking and looks at Koyomi with an amused expression "I've got an alternative for your payment of me helping you with your incident."

Ahoge standing straight up, indicating excitement, the ecstatic vampire leans forward on his seat "Really? What is it? Tell m- wait… this sounds too suspicious, what do you have up your sleeve this time, old man?" The vampire's ahoge deflating "I bet it's got something to do with the mafia, you look like the type that hangs out with them." He accuses the still amused priest with a pointing finger.

"No no, Araragi-kun, in fact, you might actually like this alternative." Oshino leans on his couch and looks at Koyomi in the eyes "I've got a few connections with some people, with me being a former priest and exorcist, so on and so forth. One of my connections needs some assistance with their work and would like you as a helper." He sets his cup down and leans back, pointing at the curious vampire, "You are going to be transferring at Youkai Academy."

*Ahoge (literally idiot hair) refers to the noticeable slim forelock of hair that sticks straight up from a character's head.

-End Flashback-

"You know, too much thinking will make your head burst."

A feminine voice disrupted Koyomi's reverie. The young vampire turned to the voice, seeing a 12 year old girl literally popping up from his shadow. The pale skinned girl wore a pink summer dress with a black ribbon in the torso, a golden necklace around her neck, an aviator cap with goggles resting on top of her waist length golden hair with the tips curving up, and wore nothing on her feet. She's probably an example of a perfect lolicon. Her golden eyes stared at Koyomi for a good amount of time, hands at her hips, a light smirk forming on her face, before finally speaking,

"Stop worrying, you'll be fine, you know I'll be there with you the whole time."

Koyomi sighed, "I just don't know if this academy is legit or not. I've tried and looked up Youkai Academy on the internet and I've gotten no results at all. It's like the place doesn't exist! Something must be suspicious…"

Walking up to the now contemplating vampire, the girl jumped and smacked Koyomi in the back of the head before she crossed her arms and narrowed her eyes at him. Koyomi then realized that he probably should stop pissing off her companion.

"Like. I. Said-" Making sure to emphasize the last word, she hissed.

She narrowed her eyes at him even further and leaned forward, the now nervous Koyomi leaned back and put his hands up in defeat, trying to placate the miffed girl and interrupted her "Okay! I get it, Shinobu, I'm probably worrying too much just like you said, let's just hope you're right." Smirking at her small victory, she harrumphed and looked away with puffed cheeks. Then looking at him again, she stifled a small gasp, he was smiling at her, small fangs protruding from his mouth, a conveniently placed breeze making his hair wave around, making her blush lightly at the site of his handsome appearance.

"Thanks for the encouragement." Calmly stated by the young vampire.

Reddened cheeks darkening a bit more, she looked away again. She heard a vehicle approaching, turning to see the bus that would take them to their new academy. Shinobu gave another look at him before sinking back into his shadow again, and spoke parting words "Stop worrying."

Koyomi mouthed a small thank you at her receding form and looked at the approaching bus. As the bus stopped and the doors opened, he was greeted by a strange man with stranger eyes that seemed to glow under the shadow formed from his hat. Smoking a cigar, the man chuckled quite menacingly before looking at him in the eyes and asking the young vampire a question,

"So, you a freshman at Youkai Academy?"

-Youkai Academy Bus Stop-

As Koyomi steps off the bus, carrying his luggage with him, he hears the bus driver chucking darkly before driving off into nowhere. He thinks about the conversation he had with the bus driver during the trip.

-Mini flashback-

"So boy, you ever seen a real monster before?" The bus driver looked at Koyomi from the front of the vehicle with his rear-view mirror.

Koyomi looked back at the bus driver, carefully thinking about his answer 'Is he inhuman as well? I think I can see why he has those strange eyes. I wonder what I should say, should I play dumb or tell him seriously?'

As if the young vampire's mind was read, the bus driver spoke again "Don't play dumb, I can tell you're not human." The bus driver took another puff of his cigar. "Be careful boy. Youkai Academy can be a very scary place." The bus driver warned, while chuckling.

"I can take care of myself, thanks." Koyomi answers, staring nervously into the glowing eyes of the bus driver.

-End Mini Flashback-

'Taking care of 3 vampire hunters with ungodly abilities most likely means I can take care of myself' the young vampire thought.

Shaking his head, he looked at his surroundings. The bus stop sign looked as if it doubles an ineffective scarecrow, the dead trees surrounding him looked like the result of a forest fire. The sea tinted red, looking almost like blood. He spotted the academy and noticed lightning striking periodically behind the academy. Koyomi sweat dropped, and swore his luck. Sighing, he grabbed his luggage and began to walk down the trail.

A good 5 minutes of walking, Koyomi looked around again. Mist started to roll in the forest, the trees looked as if they were slowly inching towards him. The design of the school reminded him of Dracula's Castle. He swore the crows sitting on the tree branches were looking AT him as if he were tonight's dinner, and that damn lightning just won't stop.

He sighs for the umpteenth time, muttering "I knew something was suspicious…" as he trudges towards the academy.

Shinobu popped out and says "Watch out, you've got company." and went back in from his shadow.

Truth be told, he heard the ringing of a bicycle coming towards him "COMING THROUGH!" a feminine voice called out. Koyomi notices a female speeding towards him at a very dangerous position, and noticed that she was about to fall over. He merely sidestepped out of the way, arms stuck out, trying to catch the young woman from the waist. As the bike zooms ahead, Koyomi manages to save the young woman from a certain bicycle related doom.

As the young vampire carried her bridal style, he performed a quick look-over at the dazed female.

Bubblegum pink hair that went down to her waist, emerald eyes on a very cute face. Wearing what seemed to be the school uniform, consisting of a green blazer with white outlines, buttoned up just right to accentuate her cleavage from her D sized breasts, even further accentuated by her choker linked to a cross necklace with a ruby gem in the middle. A brown plaid skirt accompanied with knee socks that could be ranked D in a zettai ryouiki** scale. On her feet were the standard academy shoes. Koyomi would give her an 8 out of 10 in the moe factor, not that he would say that out loud.

Setting the young lady down on her feet, he puts his closed fist in front of his mouth and coughs "You okay there, miss?" as he eyes her with concern.

Getting out of her daze, she exclaimed "Oh! I'm very sorry for all that, I missed breakfast on the way and I'm also anemic." Setting her gaze down, she made a small pout before looking back up and performed a 100 megawatt smile "I'm Akashiya Moka, thank you for helping me. I hope we can be friends!"

'Gah! That smile can blind a normal man!' Koyomi thought. "Ah, no problem, miss. I'm Araragi Koyomi. I just transferred here today. I arrived a day before school starts and I was just on my way to the chairman's office so I can get my living arrangements and all that jazz."

A small feminine cough brought the two out of their introductions and Koyomi exclaimed "That's right! I've got to go miss, I hope you are well enough to do what you are doing, as I've got to go. It's a pleasure to meet you, and I would love to be friends with you. I'll see you at school, okay? Bye!"

With that, he grabs his luggage and runs off, leaving a wave behind his back.

"Jeez, save everyone you happen to meet why don't you?" a voice behind his back mutterred angrily.

"Sorry Shinobu, couldn't let such a pretty girl be harmed now can I?" Koyomi replied, putting on a grin as the young vampire continued to run toward the academy. 'Maybe this school won't be as bad as it seems' Koyomi hoped.

"Hmph, whatever." making a puffy face, she settled back down into his shadow.

-Back to Akashiya Moka-

Continuing to stare at his fading form, she blushed at the thought of him. 'He's a very handsome fellow, and he smells delectable. I wonder what his blood tastes like…' She started to drool at the thought before wiping it off and shaking her head 'No! I won't force him to give him his blood, I've already made my first friend and I won't drive him off!' she declared with her fist raised up in the air, then walked up to her now damaged bike and sigh. She picked it up and walked to school

"Araragi-kun, my first friend." She said to no one, smiling.

** "Absolute Territory" (zettai ryouiki in Japanese) describes the area of uncovered thigh between the skirt and the stockings that's apparently a total magnet for Male Gaze. The proof that when it comes to sexiness, less is more.

-Back to our main character-

Walking up to the hall that the pretty assistant told Koyomi to go, he stopped in front of huge double doors with the name plate on top stating 'Chairman'. Before he can knock, a voice inside the room called out to him,

"Come in Araragi-kun, I've been expecting you."

The tone of the voice inside the room caused an the young vampire to raise an eyebrow. Opening the door, he was greeted by a person clad in white robes, the hood covering his face, eyes giving off the similar glow to that of the bus driver. He was seated behind a work desk filled with various documents and strange items.

Koyomi entered the room and closed the door, then walked toward the cloaked figure, taking his luggage with him. As he walked towards the robed figure, he looked around the room. His office looked pretty barren and felt very shady, to his left was a large window that overlooked the entire area. Stopping a few feet from the chairman's desk, he sets down his luggage.

Koyomi looks at the man before bowing, "It's a pleasure to meet you, sir. I assume you already know who I am." Spoken as a statement rather than a question.

Chuckling, the robed man placed his hands on the desk, fingers interlocked. He leaned forward and spoke,

"Indeed young lad, I heard from Oshino about your little predicament. I am Tenmei Mikogami, an exorcist and one of the three Dark Lords, but we'll discuss that when the time comes. I'm here to greet you to my humble academy." His hands performed a spreading gesture, "I assume that you do not know what use I have for you?" Seeing as the young vampire shake his head a negative, Mikogami stood up and walked to the window, looking over the mingling community.

"Every 3 years, we invite a human to this academy to see whether he or she can make it throughout the year, think of it as a social experiment. Cruel you may think, but my purpose for building this academy is to build a bridge between the human community and the monster community."

He turned to face Koyomi "Now I know you're not a human, seeing as how you're a Kaii Killer, but your sealed state makes you very much human and I've decided to perform a new experiment. What it is, I won't tell you yet, just know that I'm expecting a lot from you, Araragi-kun."

A scoff coming out from the room caused the exorcist to look around.

"Thou art thinks that he's the only Kaii Killer around," Shinobu pops up from Koyomi's shadow, inducing a curious look from Mikogami "I am the one that turned him into a Kaii Killer, mind you, you would do well to acknowledge his predecessor, O exorcist."

A small gasp escaped Mikogami's lips "Is that you Kisshot? It's been a long time, old friend."

He performed a small bow to the chibi vampire, not to insult, but to respect.

Shinobu walked towards the exorcist and flicked the exorcist in the area where his forehead would be, eliciting a hiss from the exorcist, and stepped back with her hands at her hips.

"Indeed it has, thou hast been thinking that you would not recognize me, how are the other two dark lords, Bloodriver and Fuhai?" A smirk forming in her face, "Enough about that though, I act as his familiar and a form of seal, with my permission, I can unseal him. It is also reciprocated, I am sealed and he has the power to unseal me, pretty convenient I would think. Call me Shinobu in my sealed form, I don't need anyone knowing my true form yet. Perhaps during school, seeing as how this facility is a school of Youkai or monsters, violence among the community is bound to happen, no?"

The amused and surprised exorcist laughed and walked towards Koyomi and put his hand on the young vampire's shoulder "It's going to be interesting with you around, Araragi-kun."

Going back to his desk, he sat back down. "Now, living arrangements. I can set you up in one of the staff dorms alone or I can set you up in a staff dorm with a roommate, I can leave that up to you for tomorrow, but for now, stay in one of the temporary guest rooms inside the academy. Seeing as you don't have the weaknesses of a regular vampire, the water system in the rooms I mention is also used by the students, so I doubt that you'll be getting any hot water."

He chuckled "I can have my assistant show you the way later."

The chairman opened a drawer and pulled out a piece of paper. He closed the drawer and gave the piece of paper to the young vampire. Koyomi took the piece of paper and inspected it.

"What you have there is a form for a school uniform, you can fill it out and choose your size." Mikogami coughed before saying "Now, as for your source of blood, you will have to pay for your blood supply, or take from a willing friend, I doubt you can't make friends, seeing as how you have already made friends with a fellow vampire."

Koyomi widened his eyes at the exorcist's statement and spoke "You mean Akashiya Moka is a vampire? She doesn't look like one." Thinking about her for a second, he remembered the choker that was linked to a cross necklace, "That necklace she has, that's a seal isn't it?"

The exorcist nods his head, "She chose to have a special form of seal that I made, a Rosario, so that she can make friends, since she's had trouble making friends unsealed. I'll let her talk about it to you, it would be nice if you were friends with the troubled vampire."

The ignored chibi-vampire mades her presence known, "What kind of vampire is she?" curiosity on her face. "Having lived for over 500 years, it is always nice to see a fellow vampire, besides my servant and those damned vampire hunters."

Mikogami cocked his head, wanting her to explain further, but decided not to and continued "She's considered an S-Class vampire." The revelation incited a curious expression from Koyomi and laughter from Shinobu,

"That so! Such a strong vampire for her age, I can't wait to see what she's made of!" snickered the chibi-vampire.

That caused Koyomi to bonk her on the head, making Shinobu cringe in pain.

"Ah! Fool! Why did you do that?" asked the irritated chibi-vampire.

"Now, Shinobu. We can't start unnecessary trouble for others." scolded the young vampire "We're not gonna test anyone without their consent."

He gave the exorcist an apologetic look.

The chibi-vampire harrumphed while she crossed her arms and looked away, face puffed up in anger.

The altercation between the two vampires caused the chairman to chuckle, "My, you two act like a married couple. Perhaps you two already are, eh?"

That made the duo to blush and cough, sputtering excuses. Continuing to chuckle, Mikogami started thinking if he forgot anything else, and he does. Clearing his throat, he catches their attention again, "I also received a package from Oshino. He said it was your bike, it is kept with my assistant at the moment, and you can receive it later. One more thing," he pulled out a small cross accessory with a strap from within his robe. "This is for your phone, you may have noticed that you have no signal."

With that, Koyomi pulls out his phone and sees that there really is no signal.

"This is because of the Great Barrier I have placed within this area, it separates Youkai academy from the human world, a downside to this is that the barrier causes the climate to be very different, causing the vegetation to die down, as you can see with all the dead trees, so on and so forth." he offers the accessory to Koyomi, and the young vampire accepts it and fixes it into his phone, moments later he receives a signal from his phone.

"Thanks for the strap, chairman-sama. I will treasure it." A grateful look on the young vampire's face.

Nodding, he says "Now, I believe I have kept you here long enough, feel free to explore the academy, curfew is at 10 P.M. and school starts at 8 A.M. tomorrow morning, don't be late and good luck, have fun. You only go to high school once."

With that, Koyomi bows again, Shinobu nodding her head then receding in the young vampire's shadow. The exorcist chuckles as he watches his investment walk out the door.

"Now, what hijinx will you cause, Araragi-kun?"

Getting his bicycle from the same pretty assistant from before, with luggage and uniform in hand, he travels to his temporary room that was pointed out by the assistant. He looks at the clock on his phone, seeing the time indicating it was 6 P.M., he stops at the door to his room. He unlocks the door with the key given to him by the assistant and steps in.

'I really should thank that assistant for putting up with me all day' the young vampire thinks as he closes the door.

Looking around the room, it's big enough to fit 4 people. The living room, smack dab in the center of the room, consists of a beige carpet floor, the walls painted in the same color with the furniture, a large couch in the and 2 accompanying small couches in each side with a coffee table in the middle, colored in a contrasting ruby red. The television is placed in front of the large couch. Connected to the living room is a decent sized kitchen, located to the left, with pots and pans hanging on hooks on top of a sink. An electric stove with an oven built in is placed to the side of the sink. A microwave is seen on top of a marble topped counter across the sink, a plate rack beside the microwave. Drawers on the counter reveal spoons, forks, chopsticks, and various cooking utensils. He opens the fridge located in the corner of the kitchen and finds a few blood packs with a note from the chairman,

'I know I said that you need to get your own blood supply, but a few can't hurt.'

-Tenmei Mikogami

The young vampire smiles and closes the fridge.

Walking to the bedroom, located across from the kitchen, he spots a king-sized bed at the end of the room. A nightstand was placed from each side of the bed, with a lamp on each nightstand. At the left of the bedroom, he spots a bathroom. The bathroom contained a marble sink with a stylized mirror on top, the faucet with both hot and cold water knobs, though as the exorcist said, the only temperature he would get will be cold and freezing cold. A bathtub is placed on the side of the bathroom, with a shower next to it. White tiled floors are placed in the bathroom, with no spot of grime and dirt, giving the bathroom a blinding white appearance. Walking out of the bathroom, he spots a large vanity mirror across the bathroom. Next to the mirror is an empty closet upon inspection.

'Man, this room is bigger than my room back home. And it's a guest dorm as well! Living in this academy probably won't be as bad as it seems.' the excited Koyomi smiles and sighed with contentment.

Walking to the bed, he sat down, and then proceeded to lie down, feet still on the floor. Closing his eyes, he thought about the female vampire he met while heading towards the academy.

'S-Class vampire, huh,' he thinks 'maybe I can be friends with her.'

A small shuffling is heard and the feeling of someone straddling him interrupts the young vampire's thoughts. Opening his eyes, he sees the not so chibi-vampire looking down at him and smirking, a small blush on her face. Her mature form stirring something within the young vampire, he blushes as well. In her mature form, Shinobu's appearance is that of a very sexy 22 year old female, her summer dress turning into a nightgown, showing her pink lace panties. Her breasts turning from a washboard into DD sized marshmallows. With the not so chibi-vampire's aviator cap nowhere to be found, her hair freely moved all over the place. Her now ruby red eyes gaze upon Koyomi's.

Forming a small pout, she whines "I'm hungry."

A devious smirk falling on the young Araragi's face he sits up, holding the not so chibi-vampire in place by wrapping his arms around her child bearing hips. He tilts his neck to the side, still gazing at the now drooling sensual vampire. "Go ahead." he whispers.

And with that, fangs protruding from her mouth lengthening, she leans slowly towards his neck. Sniffing his scent, she lets out a satisfying sigh, his scent always seems to make her very relaxed and aroused.

As she comes even closer, Koyomi can feel her hot breath in his neck, sending shivers down his spine. Her chest pressed to his, her mile a minute heartbeat can be felt, causing his pants to tighten slightly.

Feeling a protrusion in her panties, the sensual vampire lets out a yelp before finally sinking her fangs into his neck. Causing the young vampire to stiffen then relaxing into the bite. Slowly coaxing out the blood from his body, she lets out a small moan within her mouth as she tastes his blood. She always can't get enough of his blood, the smooth texture flowing down her throat, the sweet and irony taste, a good mixture of nutrients and vitamins.

For Shinobu, it is literally her elixir of life, for she can't survive without it, and prolonged denial of his blood will cause her to die.

Letting out a sigh of contentment as she continues to coax out his blood, the young vampire's hands roam around her back, before finally settling on her plump cheeks, giving it a light squeeze, causing another moan to voice itself inside her mouth.

"Shinobu, that's good enough." He breathes out.

To both his and her disappointment, Shinobu reluctantly lets go of his neck, licking the wound close before looking back up at now glazed Koyomi. Small pants coming out of Shinobu, a small amount of blood dripping on her mouth, the young vampire leans in and licks it off before finally kissing her.

Yet another small moan forms in the sensual vampire's mouth, surprised at the forcefulness of the usually relaxed Araragi. Arms now wrapping around his neck, both go into a deeper kiss, tongues battling in a playful manner.

Minutes of literal tongue twisting later, both separate, leaving a small line of blood mixed saliva between them, pants of breath coming from both vampires relaxing into deep breaths.

Looking at the clock at the nightstand, 7:30 P.M., the young vampire looks at his female counterpart and grins while saying "Want to take a bath? There's a wet spot on my pants."

Mischievous smirk forming on her lips, she agrees "And whose fault is that now? Come. I am not finished with you yet."

Dragging the young vampire to the bathroom, both enjoy a two hour bath consisting of laughter and moans.

Getting out of the bath both are dressed in sleepwear, Koyomi wearing just a blue plaid pyjamas and slippers on his feet, and Shinobu still in her adult form, wearing a see through blue negligee. Koyomi looks at the clock, 9:35 P.M., seeing the now sleepy female vampire, he smiles at her and says "Let's go to sleep, no? Big day tomorrow." Shinobu grunts an affirmative and Koyomi proceeds to carry her bridal style to the bed.

Laying her down on the bed, he goes to the other side and lies down. Shinobu goes to spoon against the young vampire and sighs a good night. Forming another smile, he brings up the sheets to their shoulders and closes his eyes.
