I'm back! Kinda. Haha. So I know it's been a while since my last update, but I wasn't sure how the next chapter should go. Well I finally figured it out and so here is the next chapter. Every good story need a villain! I'm glad I waited to update, otherwise I likelt wouldn't have been happy with what I did. I'm happy with this and looking forward to further development! Remember to send in those reviews, they keep me going! Enjoy!

I don't own Ao no Exorcist/Blue Exorcist, only the ocs created for the story.

Darkness spread throughout the crowded streets of Tokyo. People hurrying from point A to point B. Some going home from a busy day at work, while others were going out to meet friends. Among those unsuspecting humans, a demon of immense power wound his way through them, his deep crimson eyes searching for just the right one; a human to add to his strength, giving him the power he'd need to take down his next prey.

He found what he was looking for in the form of a small female, not paying attention to her surroundings and accidentally bumps into him. She let out a cute little gasp of surprise, falling backwards as she lost her balance.

His speed was among the fastest of his kind and he easily caught her in his arms, keeping her from falling to the ground and dirtying her nice, clean dress.

"I-I'm so sorry!" She yells out a hurried apology, tilting her head up to look at the person she carelessly bumped into. Her eyes widened and her face turned red with embarrassment. He was absolutely beautiful!

Dark green eyes stared down at her from beneath dark brown hair that curled ever so slightly on the ends. His skin was pale, but completely flawless, and his smile…his smile made her feel weak in the knees. When he spoke to her, she felt her breath leave her lungs. "Think nothing of it, my dear." He spoke perfect Japanese, but there was a hint of a foreign accent. Russian, maybe? Still, his voice was enchanting, she could listen to it forever. "You could make it up to me by joining me for dinner, I was just trying to decide where I want to eat, but I'm afraid I am unfamiliar with the best restaurants. I'm not from here and this happens to be my first visit in a very long time."

Of course! She knew the best place to take him, and she'd be more than happy to join him, after all it was the least she could do after she so rudely bumped into him.

Looking down at her, his polite smile turning into a sinister smirk. He had her right where he wanted her; under his spell. Showing her exactly what she wanted in order to get her to go with him. Instead of a demon, she saw a beautiful man, wo harbored no I'll intentions. In reality, she was far from safe. Wrapping an arm around her shoulders, be let her believe that she was leading him to a high end restaurant, and when he pulled her away from the crowds into a deserted alleyway, she never saw the end coming.

Yukio's PoV

"The body of a young female was found this morning…." The tv was open, but Yukio wasn't paying it much attention, at least not at the moment. He ad Rin were in the kitchen, Rin cooking them breakfast, while he sat watching.

It was a Saturday and they didn't have their normal classes today, so they were both out of uniform. It wasn't unusual for Rin, but Yukio seemed to live in either his school uniform or his True Cross Order uniform. His brother might think that he enjoyed it, but come the weekend Yukio was actually glad to be able to wear something a little more comfortable. Though, since he was out of uniform, he also didn't see the need to hide his newly acquired tail either. Having it wrapped around his stomach all day got irritating and itchy. He could see why Rin preferred to keep it out, now that everyone knew about them and their parentage.

He should probably take a lesson from his brother, but he hated his demon side and even more so now that he shared the demonic features with Rin.

"…the body is the second in the last month to be found completely drained off all blood…"

This caught his attention, and as he turned to look at the small television, Yukio felt his heart slow and all the blood from his face drain away, leaving him paler than normal. "Rin, turn that up…"

Briefly Rin looked at his twin brother, before doing as Yukio asked and turns up the volume to the tv.

"…both victims had no visible signs of a struggle, though both were young females around the same age. Police are unsure how they are being drained of their blood, but occult active is the suspected cau-"

Yukio heard enough, reaching over and quickly shutting it off.

"You thinking it's demon related?" Rin asked, though his question went ignored.

Getting up, Yukio heads out of the kitchen. Taking a left he makes his way to Calista's room. All the way thinking it couldn't possibly be her. He fed her himself, she even said it was enough to last her a while. How could she possibly have gone out behind his back? No. She couldn't, it wasn't like her. Cerberus had said the last time she killed anyone while feeding was when she was a small child, unable to control her urges. Still, there was no doubt in his mind that something was going on.

Standing in front of her door, Yukio tried to think about what he was going to say. He didn't want to come off like he was accusing her of anything, but he needed to find out the truth. If she was half vampiric demon, then there had to be others.

He lifted a hand to knock, but hesitated. Maybe he was just reading too much into this and it wasn't demons, but humans foolishly playing around with the occult. No, it was better to be safe than sorry. Shaking his head, he goes to knock on the door, only to find the door opening on its own.

Calista's PoV

She planned on going out and doing a bit of exploring, learning the new place she would temporarily be calling home. It was better to know your surroundings in case things went badly, rather than not knowing and being caught in a dead end, which would likely end your life. So today she was going to learn the ends and outs of not just this school, but the city it resided in.

That was until she opened her bedroom door to find Yukio standing on the other side with his fist up preparing to knock. At first she was surprised to see him, and over the last few days had learned to control her embarrassment over feeding off of him. Still, having him suddenly be standing there caught her off guard and despite her efforts, her cheeks still turned a light shade of red.

"Yukio, what are you doing here?" She questioned. Since the feeding, they haven't really spoken to each other outside of class ad missions. Even living in the same building and spending mealtimes together, they didn't exactly chit chat.

His face went from surprise, to serious in seconds. Something was wrong, but she wasn't sure what. "Have you seen the news?" He asked, letting his hand down to rest at his side.

"The news?" Why would he be asking her if she'd been watching the news? Not sure where this was going, Calista shrugs her shoulders and shakes her head. "No, I just woke up a couple minutes ago. Why?"

He pushed up his glasses, something she was starting to get use to seeing, and jerked his head to the side, indicating he wanted her to follow him. While she didn't see the harm in following, she wasn't so sure she was going to like where it led her.

Calista followed closely behind Yukio as he leads her through the hallway, down towards the kitchen. She could hear Rin talking to his familiar, as well as the sound of cooking going on. By now, she knew that if Rin wasn't on a mission or sleeping, he was in the kitchen cooking something. As they came in, she was able to just briefly see Rin going back and forth behind the counter, but the tv was what caught her entire attention.

There were two pictures, both female, both very pretty. Yukio turned up the volume and she stopped just beside him to listen. The report went on about how both girls were close in age, and that their bodies had been found just days after the other. What made the blood drain from her face was how they had been found.

Completely drained of all their blood…
