Hey people-who-actually-read-author's-notes. If you happen to be a fan of my other popular story, Harry Potter and the Fullmetal Professor, know that I'm not abandoning it. After all, it's got fifty reviews per chapter! And if you haven't read it, I suggest you go check it out after you're done reading this.

For those of you who are wondering, no, Tsukune will not be appearing in this story. There, it's been decided.

I've been kind of disappointed with the lack of good Bleach crossovers starring Ulquiorra, so of course I decided to write one myself. And so, I give you the pilot chapter of A Void with a Heart.

Disclaimer: I do not own Bleach or Rosario Vampire, nor do I stand to make any money from writing this fanfic.

Chapter 1: Becoming A Little Bit Intrigued

Hueco Mundo,

Standing atop the dome that served as the ceiling of Las Noches, Ulquiorra Cifer, the Fourth Espada, stared at the humans around him as his body faded away. Most intently, he stared at Orihime Inoue, the girl whom he had tormented, yet had told him that she wasn't afraid of him.

Ulquiorra had lost his battle with the Substitute Soul Reaper, Ichigo Kurosaki. But little did anyone realize the real reason Ulquiorra's body had begun to turn to ash. It was not because he had used too much of his spirit energy and thus his body was no longer able to maintain itself, as the Fourth Espada himself thought. Instead, in another world, a powerful magic had just been cast. And as a result of that magic, Ulquiorra was now being summoned to another place, far away from Las Noches.

Yokai Academy,

Deep within the walls of Yokai Academy, its Headmaster, Tenmei Mikogami, also known as the Exorcist, and one of the three Hades Lords, was currently in the process of casting magic the likes of which had never been cast before: The summoning of a being from another dimension.

Tenmei carefully watched the magic circle he had drawn, wondering if this spell that was requiring so much power would even work. And if it did, what kind of entity he would summon. After several minutes, his skin began to sweat due to how much power the spell was requiring, and Tenmei was on the verge of giving up when he saw it: a cloud of ash that had gathered within the summoning circle. After a little while the ash began to form what looked like a pair of feet, though after several seconds those feet seemed to look a lot more like talons. At around the same time, Mikogami began to feel this steadily growing presence, and the Hades Lord was certain that whatever he was summoning was the cause of it. As more of the being's body formed, the presence grew stronger with every passing second. The school's Headmaster was glad that all the students and teachers were away on their winter break. If anyone else had been inside the grounds at this time, they would have surely felt this massive presence.

After several minutes, most of the entity's legs, arms, and torso had formed. The ash was currently coming together to form what seemed to be a pair of wings, as well as a tail. By this point, Tenmei Mikogami was becoming seriously worried that whatever he had summoned would be too powerful, and dangerous, for him to control. After a quick glance at the crystal ball on his desk, he realized that cracks had begun to appear on the surface of the Great Barrier that kept Yokai Academy hidden from the human world.

'By Alucard's blood, this entity's mere existence is powerful enough to destroy the Great Barrier! Just what manner of demon have I brought to this world?' Tenmei wondered. He suddenly heard a sharp intake of breath behind him, and spun to see the monster he had summoned in its full form at last.

The demon had jet black fur covering its arms, legs, and back. From its shoulders sprouted a massive pair of bat-like wings. Its skin was a deathly pale ashen colour, and in the centre of its chest, was a giant hole that seemed to be dripping black blood. It had two white horns that vaguely resembled bat ears, as well as a wild mane of black hair. But what was most terrifying of all, was the creature's eyes. Like the hole in its chest, the beast's eyes appeared to be dripping a black liquid, and its irises were yellow with green sclera, which were staring at him intently. Then the being spoke.

"Am I... alive?" This was all the creature sai before it toppled forward and collapsed on the ground. The instant it hit the stone floor, the beast's skin as well as its wings and tail seemed to break away as it turned into some kind of greenish-white mist. The mist solidified, in the form of a sword of all things, and clattered to the ground. The instant that happened, the crushing presence disappeared, and Tenmei eventually allowed himself to relax as he saw the cracks in the Great Barrier slowly begin to repair themselves. So since that crisis was over for now, the Exorcist finally took a moment to take a closer look at what exactly he had summoned.

The creature was now wearing a white hakama, and was much more human in appearance than when it had first arrived. The only abnormality being the half-helmet which seemed to be made of bone the creature wore on the left side of its head. When Tenmei turned the entity over, he saw that it also still had a hole in its chest, though it was now much smaller than before. After that, Tenmei turned his attention to the entity's sword as he picked it up.

"Interesting. The vast majority of this creature's power seems to have sealed itself away in the form of this sword." Tenmei muttered to himself. Whatever this thing was, it could still be quite dangerous. Tenmei thought it would be a shame to have summoned an extra-dimensional being for the first time in history, and immediately have to kill it. As Tenmei pondered what to do, he inspected the beast's energy levels briefly, before realizing that they were dangerously low, and without more it would die soon.

Deciding that a living specimen was much more interesting than a dead one, Tenmei Mikogami began taking the steps needed to keep the creature in a suspended state of animation. After that was taken care of, he started transferring the energy he could spare to the creature. The whole process was excruciatingly slow, as the creature obviously required incredible amounts of energy just to maintain itself.

As the weeks went by, Tenmei would often attempt to tap into the massive stores of power sealed within the creature's sword. Though these efforts were never met with any success. Occasionally Mikogami considered waking the creature, and giving it its sword back to accelerate the healing process and see what it would do, but always deciding not to, just in case the entity turned out to be hostile. The Hades Lord knew that if he ever did have to fight against such a titan, he would prefer to do so when said titan was unable to utilize its full power.

It wasn't until winter had nearly ended that the creature Tenmei had summoned had finally gathered enough energy to sustain itself. When that happened, the Hades Lord finally released the entity from the animated field that he had placed it in to keep it alive. The creature itself landed on the floor in a crouch as it became alert.

The being slowly stood with its back straight, and eventually opened its eyes, which Tenmei finally saw bore normal white sclera, and green irises with slitted pupils. It then brought its right hand up to eye level and stared at it, flexing it experimentally as if to confirm that the hand it was looking at was real. The entity then swept its eyes over the room before focusing on Tenmei Mikogami, and then it spoke to him.

"Who are you, and how is it that I came to this place?"

"I am Tenmei Mikogami, the Headmaster of Yokai Academy, which is where you are now. And the reason you are here is because I summoned you." The Hades Lord said, smiling politely and giving a small bow as he introduced himself. "Now, if you don't mind, I'd like to know your name."

The entity regarded Tenmei's words for a moment before responding, though it didn't answer his question. "You say you summoned me? How did you accomplish this, and what made you choose me?"

"The summoning ritual I performed was the first time anyone had ever done it. As for why you specifically were summoned, I honestly don't know. Like I said, I'm the first person in history to summon a being from another dimension. So my knowledge as to the details of this ritual is somewhat limited."

"Another dimension?" The creature said curiously. Then after a moment its eyes were filled with understanding. "Ah, it seems that through some form of magic, I have been brought to the world of the living." It then looked back at Tenmei. "You said this place is Yokai Academy, and that you are the Headmaster. Clarify."

Tenmei felt a hint of annoyance at being commanded so blatantly, but decided to oblige. It was only fair since the being in front of him was rather confused - rightly so - and he was the source of this confusion.

"Yokai Academy is a school specifically meant for monsters. You see, most of the world is completely overrun with humans, yet they know nothing about the existence of us monsters. Yokai Academy teaches its students how to blend in with human society. We do this so that we can coexist with them peacefully, while at the same time giving the students the academic knowledge that they'll need to succeed in life." The Exorcist explained.

The entity seemed to mull over his words, thinking carefully. After several minutes it asked "You say that this academy teaches non-humans how to interact with humans?"

"Indeed. Why?"

The creature's eyes suddenly glared at the Hades Lord with suspicion, before reluctantly answering. "My reasons are my own, though I will say that recently I have become rather intrigued with the way humans behave, and why they make the decisions that they do. Additionally, I feel you should know that by me being summoned here when I was, I have failed in my service to my lord. And he is someone who does not forgive failure. As a result, I cannot return to my world. It is for these reasons that I would like to attend this Yokai Academy, if you would allow it."

The Headmaster's eyes actually widened in surprise at this declaration. Then after a minute he smiled. "I believe I can accommodate your wishes, just let me grab a student application form," He said, reaching into one of his pockets. Though after a few seconds of rummaging, it was clear that the forms weren't there.

'Did I drop the application forms?' He wondered. Then his eyes widened. 'Oh no, what if I left them somewhere when I went to the human world earlier today? What if a human fills them out? Wait, why am I panicking? I can solve this little problem in less than a minute.' Tenmei then raised his hands as he cast a quick spell. An instant later the application forms fell into his hand. Thankfully, they hadn't been filled out.

'That's a relief. If a human had come to Yokai Academy, they'd have been eaten for sure.'

Aono Residence,

"Honey, you said that you found some forms that would allow my sweet and adorable Tsukune to go to high school this year, instead of having to wait and spend the year living in shame as a dropout?" Kasumi Aono called out to her husband, Koji.

"You bet! I've got them on my desk. Let me go grab them right now and prove that I'm the best dad ever!" Koji said triumphantly to his wife before he skipped over to his home office, and then burst through the door feeling like a conquering hero ascending to his throne.

...A feeling that ended the instant he actually looked at his desk.

"What! No! I swear I had them right here!"

Yokai Academy,

"Now, since I'm allowing you to attend my academy as a student, I'm afraid I'll have to ask for something in return." Tenmei said as he handed the being he'd summoned the application forms

"Tell me what it is you want," The entity responded without hesitating as it took the papers in its hand.

"As you can probably imagine, there are some monsters who don't want to live alongside humans peacefully, including those who attend this school," The Headmaster explained. "So when I founded this academy, I created the Student Police to help maintain order. However, they've become... unreliable in recent years. And so for that reason, I would greatly appreciate it if you would do what the Student Police have failed to, and protect Yokai Academy as long as you are here."

The creature considered his words briefly before answering. "Such a simple task is well within my abilities. I will do as you ask, Tenmei Mikogami."

"Wonderful. Now, before you start, you should know that while you are permitted to use force when the situation demands it, you are not allowed to kill anyone as long as you are a student here, is that clear?"

"Perfectly."

"Good, now there's just one more thing. In order to ensure that the humans never discover us, Yokai Academy is kept hidden by a powerful barrier. Yet when you first arrived here in what I assume was your true form, your power was so great that you nearly destroyed it. So for that reason, I must ask that as long as you are within the grounds of the academy, you never unleash your true form."

As Tenmei finished speaking, the creature's eyes suddenly widened. "My Zanpakuto... where is it?"

"Your sword?" The Headmater guessed as he walked over to where he had been keeping the blade. "It's right-" The Exorcist felt something rush past him at an incredible speed, and when he looked back up he saw the entity holding its sword carefully. Looking it over for any signs that it had been tampered with. Apparently deciding that nothing was wrong with it, the being slid the sword into the sheath at its side.

"I'm guessing that sword is important to you?"

The creature was silent for a moment before simply saying, "It is." and leaving it at that. It then promised, "You have my word that I will not release my full power whenever I am within the confines of the academy's barrier." The being then walked over to where it had dropped the papers for the school application, and began filling them out.

After watching the entity for a couple more minutes, Tenmei said to it, "If you are going to be a student of my academy, I would like to know your name, and just what you are."

The creature stopped writing, then turned to face the Headmaster.

"My name is Ulquiorra Cifer. And I am an Arrancar."

A couple weeks later it was spring, and another year was starting at Yokai Academy. Most of the students were currently inside the school's main building, waiting for the entrance ceremony to begin.

Not Ulquiorra. He was currently outside, staring at the academy's large lake.

There wasn't even a drop of water in the endless desert of Hueco Mundo, and all of his previous visits to the world of the living had been on missions as part of his service to Lord Aizen. So Ulquiorra had never had the time to really look at it before.

But now that he was here, it was impossible for him to not notice the giant body of water that existed right on the academy's doorstep.

As Ulquiorra had watched the lake during his spare time before the school year started, he'd noticed the way it caught the light of the sun during the day, and how at night it reflected the moon and the countless stars that decorated the sky. And as the hours of the day went by, the colors would change, a different pattern decorating the surface of the water every minute.

It was... strangely pleasing to look at for the Arrancar.

Hearing the school bells ring off in the distance, Ulquiorra realized that the ceremony was about to start, and began making his way back the the academy at a leisurely pace. He was wearing the school's male uniform, though he had left the top half of the outer green jacket unbuttoned. He also wore a silver ring adorned with several tiny green jewels, which Tenmei Mikogami had helped him create, on his right hand.

This ring served to complete his disguise as a human by concealing Ulquiorra's mask fragment, his Hollow hole, his Zanpakuto, and even his white hakama and Espada tattoo. Unfortunately, the ring also restricted Ulquiorra from using two of his abilities, namely his Cero and Bala, and it had also lowered the effectiveness of his Pesquisa, Hierro, and Sonido techniques. However, the Espada still retained his regenerative abilities, as well as his natural speed, strength, and his ability to stand on Reishi.

As Ulquiorra walked, his Pesquisa, limited though it was, detected someone approaching from behind. Looking back, he saw a young girl with long pink hair riding a bicycle. Though after only a glance, it was clear that the girl was not fully awake, and was quickly losing control of her bike. Because of that, she was about to crash, either into him or one of the many trees that adorned the path to the school's main building.

Stepping out of the way of the girl, Ulquiorra wrapped his arm around her waist and swept her off of her vehicle. The bike itself collided with a tree not two seconds later.

After a minute, the girl seemed to regain awareness, and as soon as she did, she stared at Ulquiorra with very apologetic eyes. "Oh, I'm sorry! I didn't hurt you or anything, did I? I got dizzy because of my anemia, and I couldn't control where I was going. I'm very sorry, really!"

Ulquiorra wordlessly released the girl. As she looked at him, her eyes were suddenly overtaken by a faraway look as her arms came up to encircle him.

"That smell..." The girl whispered as she held him. "It's like you have the energy of a thousand people flowing through your veins. I've never smelled anything like it before but... it smells really really good." And then she tried to bite him.

The key word being tried. Even though he knew his Hierro would protect him, Ulquiorra moved his hand to intercept the girl's mouth, before pushing her away from him. Instantly the girl's apologetic demeanour returned in full force.

"I'm so sorry! I just couldn't control myself! You see... I'm a vampire."

Ulquiorra simply gave her a measuring stare. "A vampire, you say?"

"...Yes." The girl whimpered as she poked her index fingers together awkwardly and stared at the ground. "Do you... not like vampires?"

Ulquiorra calmly answered "I have never encountered a vampire before now, so I have no reason to like or dislike them."

"That's great!" The girl said as a smile came over her face. "Then if it's alright with you, would you please be my friend? I was just feeling lonely, since I don't know anyone here yet."

Ulquiorra was about to give the girl a negative response, but then he remembered the reason he had come to this academy. If he was ever going to understand other people, the fact was, he would have to interact with them.

"...If that is what you want." Ulquiorra eventually said. Then he resumed walking.

The vampire girl jogged a bit to catch up to him, then she wrapped her right arm around his left one. "Thank you so much! My name's Moka Akashiya, and if you're okay with it, can we meet up again and talk more after the entrance ceremony is done? Oh, I'm being rude, I don't even know your name yet!"

The Arrancar continued walking for several seconds before responding.

"Ulquiorra Cifer, that is my name."

Class 1-3 of Yokai Academy,

The entrance ceremony was now finished, and Ulquiorra had just taken his seat in his assigned homeroom with the rest of his fellow students just as the teacher began talking in a cheerful tone.

"Well hello everyone, and welcome to Yokai Academy. My name's Shizuka Nekonome, and I'll be your homeroom teacher this year. Now, I'm pretty sure all of you already know this, but just to be safe, I'll tell you anyway. Yokai Academy is an incredibly unique school. It's a school for monsters! You see, like it or not, the fact is that humans control the planet. So in order for monsters like you and I to survive, our only option is to learn how to coexist with them, which is what you'll all be learning here! And that really brings us to our first rule: As long as you're on campus, unless there are special circumstances you must always remain in your human form. Everybody got that?"

When several students nodded, Ms. Nekonome smiled. "Wonderful! Now, rule number two: Never ever reveal your monster identity to another student, okay?"

"Ha! These rules all sound like bullshit to me," The boy sitting next to Ulquiorra declared loudly. "If I ever meet a human, I'll just eat them. Unless it's a pretty girl of course, in which case I'll molest them."

"If that is what you truly think, then what is trash like you even doing at this academy?" Ulquiorra wondered.

"What'd you say!" The boy snarled as he spun to face the Arrancar.

Barely even turning his eyes to look at him, Ulquiorra said, "The reason Yokai Academy was founded was to allow monsters and humans to coexist with one another peacefully. If you do not understand even that much, your intelligence must be even lower than your appearance would indicate."

There were several snickers throughout the classroom, and the boy Ulquiorra had just insulted looked like he was about to fly into a rage. "Shut your mouth, asshole! I didn't even want to come here! But apparently I was too much of a badass ladies man, and I was forced into this stupid school!"

"That's enough! No fighting in the classroom! ~Meow~" Ms. Nekonome shouted as a cat tail poked out from under her skirt.

After the temperamental boy took his seat again, the teacher looked at her class sheet and said, "The two of you are... Saizo Komiya and Ulquiorra Cifer, is that correct?" When both of them nodded she announced "Ulquiorra is right: The reason Yokai Academy exists is so that all of us monsters can learn how to get along with humans. And Saizo, it's not like there's any humans in here anyway. You see, Yokai Academy is kept hidden from the humans because it's inside of this giant magical barrier. Besides, even if a human did manage to get inside somehow, they would be killed immediately!"

Before anyone could say anything else, the classroom door opened and a timid feminine voice said "Um, excuse me? I'm sorry I'm late, but I got lost after the entrance ceremony."

Ms. Nekonome smiled. "Oh that's fine. Just come in and introduce yourself, and then take a seat wherever you'd like." And with that, Moka stepped through the door, and into everyone's view.

Shyly, the vampiress looked at what seemed like a small ocean of faces in front of her, and gave a small bow before saying "Hello, my name's Moka Akashiya, and it's really nice to meet all of you."

Instantly, every male in the classroom aside from Ulquiorra went into a frenzy.

"Holy shit! That has got to be the cutest girl on the planet!"

"I think I can die happy knowing I was in the same class as this hottie."

"That long pink hair.. and those adorable eyes of hers... I think I'm in love."

"I swear on my life, I am going to marry this beautiful girl."

"She is so fucking hot!"

Moka herself actually seemed embarrassed from all the attention she was suddenly getting, and tried desperately to find an empty desk somewhere out of everyone's way. As luck would have it, there was one such desk at the far side of the room, and the person sitting in the desk in front of it was...

"Ulquiorra!" Moka screamed, her face lighting up in pure joy the instant she'd seen her new friend, and she leaped directly at him. Ulquiorra, having not anticipated such a reaction from the girl, barely had time to catch her.

The end result was Moka sitting in Ulquiorra's lap with both of her arms around his neck, and her cheek nuzzling his. Ulquiorra had his left hand resting on Moka's side. Though Ulquiorra's hand was only there to help steady Moka, and prevent her from colliding with the wall after she'd jumped at him.

"I can't believe we're in the same class! And I even get to sit right behind you! I'm so happy!" The young girl squealed.

While Moka was busy cuddling Ulquiorra, the mood of every other male in the class had completely reversed from what it had been just a few seconds ago.

"What the fuck!"

"How does that guy know my future wife?!"

"I swear, I am gonna murder that bastard for touching my love with his filthy hands!"

"She's way too good for him! I should be the one getting that kind of treatment from her!"

After classes ended, Moka had insisted on staying by Ulquiorra's side, quite literally. She held his arm tightly in her own wherever the two of them walked. Everywhere they went, there were similar reactions to the ones they'd received in their homeroom. Boys would see Moka and instantly fall for her, then they'd notice the way she was clinging to Ulquiorra, and immediately either fall into the depths of despair, or begin plotting to kill him. Or both.

As they neared the end of one of the school's many hallways, Saizo was standing directly in their path.

"Hey there Moka, I'm your classmate, Saizo Komiya, you probably remember me," The arrogant monster smirked as he walked up to the pair. "So I gotta ask, what's a hot babe like you doing hanging out with a worthless piece of scum like him? I know how to show a lady like you a good time, so why don't you ditch this loser and come with me?" Smirking, Saizo then reached for Ulquiorra's throat. But before he could touch Ulquiorra, the Hollow grabbed his wrist.

"I believe that whoever Moka associates with is her decision." The Espada muttered curtly.

Clutching Ulquiorra's arm more tightly, and burrowing her head into his shoulder, Moka nodded. "That's right! I prefer to hang out with nice guys like Ulquiorra!" When Saizo's face contorted with anger, Moka also noticed the way Ulquiorra's muscles had tensed slightly in response. She then said to her friend, "Can we please leave, Ulquiorra? I really don't want us to get in any trouble on the first day of school."

Shifting his eyes to look at her, Ulquiorra slowly answered "...As you wish." And with that being said, the two of them began walking up the closest staircase.

Saizo narrowed his eyes, as he watched them leave, before making a promise to himself. "Don't think I'll give up on you that easily, Moka Akashiya. The next time I see you, that bastard Ulquiorra will be dead, and you'll be my woman for the rest of your life."

Roof of Yokai Academy,

"I can't believe you stood up to Saizo like that, Ulquiorra. You were so brave!" Moka smiled. "So I've been meaning to ask, what kind of monster are you?"

"You do realize that if I told you that, I would be breaking one of the rules of this academy?" Ulquiorra reminded her.

"Oh, right! Sorry, I can't believe I forgot." Moka giggled, embarrassed. "I didn't know that was a rule when I told you that I'm a vampire earlier, I'm sorry."

"You were unaware of that rule at the time, so you have nothing to apologize for, Moka." Ulquiorra told the girl. "Although I have to say, as far as I can tell, there seems to be nothing to distinguish you from an ordinary human."

"Well, that's true right now, but that's because of this Rosary on my chest." She said, showing the silver cross affixed to a collar around her neck to Ulquiorra so he could see it clearly. "If this ever comes off, I'll turn into my true form, an evil and scary vampire. So I wear this Rosary to make sure that doesn't happen. You see, Rosaries like this one seal away a vampire's power. To be honest, I can't even take it off myself."

"I see." Ulquiorra murmured. 'So that's why her energy isn't any different from a normal human's. Unlike the rest of the students that are actively suppressing their energy, Moka's true power is sealed away. It's rather similar to the way I keep the bulk of my power sealed in my Zanpakuto. Yet Moka said that she's unable to release that power when she needs to. How inconvenient for her.'

"Although," The vampiress added, "even with our powers sealed away, we vampires still... crave blood..." Suddenly Moka's eyes became the same as earlier, when she had attempted to bite him.

"You smell so good, Ulquiorra... I just know that your blood will be the most delicious blood I've ever had..." As she talked, Moka reached out to him.

Ulquiorra raised a hand, and when Moka saw the halting motion she seemed to snap out of her trance.

"I'm curious." Ulquiorra said, as he gave her a sidelong glance. "When you said that you wished to be friends with me. Was it because you truly enjoyed being in my presence, or was the real reason you made such a request simply so that you would be able to drink my blood whenever the desire arose?"

As Ulquiorra finished speaking, Moka gasped, a hurt expression on her face. She stood there, her body beginning to tremble and her eyes watering. Finally the tears spilled, and Moka ran down the stairs away from Ulquiorra as fast as she could, crying the entire time.

Ulquiorra watched her leave, uncertain of what he should do. He later sensed Moka running into the forest that surrounded Yokai Academy, but decided to leave the vampire girl be. If Moka wanted to be in his company, she was perfectly capable of seeking him out on her own.

But several minutes later, Ulquiorra sensed another familiar presence go into the forest after Moka.

Forest of Yokai Academy,

Moka was sitting with her back to a tree and her legs up against her chest, crying heavily. 'Is that really the only reason I asked Ulquiorra to be my friend? So that I could drink his blood?' She wondered. 'What am I gonna do? I finally made a friend, and in the same day I screwed it up! I really should've been more considerate of Ulquiorra's feelings before I tried to bite him. What am I thinking, I shouldn't have tried to bite him at all! He probably hates me!'

"Hey there, beautiful." Moka's eyes widened when she heard that voice. "A pretty lady like you shouldn't be crying like that. Why don't you come with me, and let me help you forget all about that loser, Ulquiorra."

"Saizo!" Moka screamed as she turned to face the bully. Fear began to flood into her as she realized that they were alone.

"Damn, Moka," Saizo grinned lasciviously. "You're way sexier than any of those human bitches I've molested. I'm getting all hot just from looking at you." Suddenly Saizo's muscles began to bulge, and tear away his shirt. In a matter of seconds he was in his true form, a grotesque beast that towered over Moka.

"When I get like this, I just can't stay in my human form any longer." The monster laughed. "I'm gonna enjoy breaking the rules like this. Come on Moka, let's have some fun!"

As the beast lumbered toward her. Moka was too scared to do anything but scream as Saizo reached out to take hold of her and violate her.

Then Moka heard a pained sound come from Saizo, and the vampire dared to slowly open her eyes. When she did, her eyes shot completely open, for she was speechless at the sight before her.

"Ulquiorra..."

"Don't you dare lay a hand on her, trash." The Hollow muttered dangerously, his right arm stretched out to the side.

Just as Saizo had been about to touch Moka, Ulquiorra had appeared between the two and swatted the giant monster's hand aside.

"Moka," The Arrancar said as he glanced at the vampiress over his shoulder. "I realize that my words earlier caused you distress, and for that I apologize. I have never been particularly adept when it comes to understanding emotions, and I have never had a true friend before either. But let me be clear: If you ever feel the desire to drink my blood, you need only ask. After all, regardless of the reason why, I agreed to be your friend."

Moka's eyes widened even further. And after getting over her initial shock, she began to cry.

Seeing this, Ulquiorra frowned in confusion. "Have my words somehow caused you even greater distress, Moka? If so, understand that such an outcome was not my intention."

"No!" Moka shouted, shaking her head fervently. "I'm just... I'm just so glad that you don't hate me, Ulquiorra!" And with that, Moka ran up to her only friend in the world, and embraced him from behind in an endearing hug.

Saizo, who was nursing his rapidly bruising hand, glared at the newcomer being hugged by his dream girl with pure hatred. "Ulquiorra," The monster snarled. "I swore that if I ever saw you around Moka again I'd kill you. So that's exactly what I'm gonna do right now!"

Reaching behind him, Saizo grabbed a large rock, and threw it directly at his nemesis.

As the boulder flew toward him, Ulquiorra calmly assessed the situation. 'Even in my current state, I could easily destroy the rock with my bare hand. But that would result in a considerable amount of debris, which could harm Moka. It would be better to move her out of harm's way, and then deal with this trash.'

Still in Moka's arms, Ulquiorra spun and picked the vampire up before dodging to the side. Landing on his feet, Ulquiorra gently set Moka down before turning back to face Saizo. Though as he did, Ulquiorra's left hand accidentally came in contact with Moka's Rosary seal. And just that slight touch was enough to send the seal flying off.

Moka barely had enough time for the shock to register, before the air around her became a whirlwind as the seal was broken. Ulquiorra felt the vampire's power level skyrocket. When he looked at Moka again, Ulquiorra's eyes widened slightly in surprise.

"H-Hey, w-what the hell j-just happened?" Saizo stammered, as he witnessed the changes brought to Moka after the removal of her seal. "She looks different... and scary. That's not the same Moka."

Hearing Saizo, Moka turned to face him.

"Oh shit." Moka's attempted molester gasped. "The stories... they're true! Those red eyes, that silver hair, and this overwhelming energy... She's an S-class monster! A real vampire!"

The transformed Moka narrowed her eyes as she approached Saizo, who was shaking uncontrollably in complete terror. "To think a low class monster like you has the nerve to try to claim me for yourself. You should know your place." And with a single kick, Moka sent the giant flying easily a hundred meters through multiple tree trunks, until he finally collided with a bed of rocks.

Ulquiorra had watched the entire exchange, brief as it was. The moment he had seen Moka's new form, his Pesquisa was able to give him an idea of the vampire's strength. He had quickly determined that she was more than capable of dealing with someone as weak as Saizo on her own, and let the vampire do as she pleased. He then picked Moka's Rosary off the ground and approached her calmly.

"So this is your true form, Moka." The Arrancar observed. "I have to say, I'm impressed by the extent at which your strength has increased. And interestingly, it seems that this Rosary sealed away not only your abilities, but even your personality."

The new Moka smirked. "You've kept your composure even after seeing the power of an S-class monster first hand. Not bad, Ulquiorra Cifer." She then plucked the Rosary from Ulquiorra's hand. "But I don't have time to chat with you. I just woke up from a long nap, and I'm still tired. So until the next time we meet, you had better take good care of my more sentimental self. She still wants to drink your blood, quite badly I might add." Done speaking, Moka put the Rosary seal back on, and seconds later her hair turned pink, and her strength vanished.

Moka began to fall to the ground, but instead of the rough earth, she landed in Ulquiorra's arms. After a few seconds, the vampire blinked her eyes open, becoming fully alert the instant she saw whose arms she was in. "Ulquiorra!" The vampiress exclaimed, her face turning red. "A-Are you okay? You're not hurt or anything, are you?"

"I am uninjured, Moka, you needn't worry." Ulquiorra assured her.

"That's good." Moka smiled, relieved that her friend was alright. "Come on, let's go back to the academy."

The two them began walking the path that would take them back to the school dorms in relative silence. Though that ended after just a few minutes.

"Hey, Ulquiorra?" Moka whispered. "Earlier when you protected me from Saizo, you said that I could drink your blood whenever I need to, and I didn't have supper earlier, so..."

"Go ahead, Moka." Ulquiorra told the vampire as he dropped his Hierro, turning to face her.

Hearing her friend give his permission, Moka smiled. As she stood right in front of Ulquiorra, she began to blush furiously. "To be honest, I'm actually kind of nervous. I've only ever drank tomato juice, or the blood in transfusion packs before. So... you're my first, Ulquiorra. The first person I've ever drank blood from."

Forcing herself to go through with it, Moka wrapped her arms around Ulquiorra and put her mouth on his neck, her fangs lightly piercing his skin. A few seconds later, Moka stepped back and placed her hands over her cheeks, a euphoric smile on her face.

"Wow! That was so yummy! It tasted better than I ever imagined!"

And Ulquiorra, seeing the joy that this simple act had brought to the girl in front of him, allowed his eyes to soften just a tiny bit.

Well, there's the first chapter. What do you guys think? Did I stay true to everyone's character? Please let me know, your feedback helps me to write a better story. Rate and review!

I would also like to give credit to my beta reader, Wigles-n-stuff. And by the way, if you're up to date on Bleach manga, I highly suggest that you go check out Wiggles' story, A Hollow Queen's Dark Knight, which I myself am currently beta reading. Trust me, it's good.

As a side note, I don't want to hear any of you complaining about how "Ulquiorra's last name is Schiffer, not Cifer." If you go to the Bleach wiki, his last name is spelled Cifer, so there.

One of the hardest parts of any crossover is figuring out how to bring the two worlds together, and I can understand if you weren't exactly head over heels with the way I had Tenmei "summon" Ulquiorra. If anyone's got a better idea that sticks to the Bleach canon, I'm all ears.

Sincerely Yours,

Paragon of Awesomeness
