I'm on a roll. Haha.
So here is the chapter 10. I don't have a whole lot to say this time, but I really want to encourage you all to send in your reviews. I'm enjoying this story, but I really want to hear your thoughts. Are you liking it? Is there something about it you'd rather change or that I should include? Please let me know.

I don't own Blue Exorcist/Ao no Exorcist
I only claim the characters created for this story

Yukio's PoV

He didn't hear her right. There wasn't any way that the Vatican would suspect him of being a danger. He was an Exorcist, damnit! Since he was seven years old he dedicated his entire life to killing the demons that plague this world, fighting alongside his father; vowing to protect his brother! Just the thought alone pissed him off!

"You've been possessed by Satan once before, what's t say he won't try and possess you again." Her voice pulled him out of his thoughts and he looked back at her. "I've seen how little control you actually have over your flames."

At his side's, his hands clenched into tight fists. "All this time, you've been reporting back to the Vatican." His jaw was clench, making his words sound forced.

"No, I haven't been in contact with HQ since I left Rome."

"You've been lying this entire time, how am I suppose to believe a damn thing you say now?!"

"Listen," she turns away from him, getting onto the train that would take her into the city where the attacks have taken place. "I don't care whether you believe me or not, I have bigger things to worry about. You can choose to help me, if not, then I'm going on my own. Cerberus and I can handle this without you."

He should let her go alone, after lying to him like she had. How can he trust her to have his back in a fight, if she couldn't trust him with the entire truth? As he stood there deciding the train began to pull away, the doors closing. He couldn't trust her after this, but at the same time, he couldn't seem to stand the thought of her going off on her own and being injured. Pulling himself together, Yukio quickly boarded the train, just before the doors closed completely.

When he appeared at her side, Yukio narrowed his eyes on her. "I'm going to make this clear; I don't trust you, especially now that I know the truth. Despite that, I'm going with you, because if I don't and you're hurt or killed, it'll be on my hands for letting you go alone."

Turning his back to her, Yukio faced the door they would exit from once the train comes to a stop. With his back to her, Yukio wouldn't see her smile and nod her head, or the relief in her eyes.

Calista's PoV

She didn't know why, but she felt relieved that Yukio decided to come with her. She knew he was angry, could see that in the way his entire body was stiff, he was just barely keeping a handle on his control. While she wanted to further explain herself, she didn't want to push him any more than she already had. So instead she takes a step back, taking a hold of the metal pole, holding it as the train carried them into Tokyo.

Telling him the truth may have been the worse thing she could have possibly done, but she was honestly getting sick of hiding it. Despite what she'd been told, Yukio and his brother didn't seem like they had any hidden agendas. Rin was stubborn and hot-headed, but he was determined to defeat Satan, constantly trying to better himself in order to be come stronger.

Yukio too only seemed to want what was best for his brother, and while she could see and sense the friction between the twins, there still a bond there. Yukio cared about his brother, even though he made it seem like he hated him. Even still, she could feel that there was a seething hatred underneath it all. Not towards his brother, but towards himself and the demon side he carried. She could understand, after all he had little control over his flames and with all of is suppressed emotions, he would continue to have little control.

Honestly, she felt badly for him. Knowing what it felt like to have no control, always afraid that you'll hurt those around you. Hating the fear in the eyes of your peers. And after living his life as a human for 16 years, only to suddenly become the very thing you hate, would drive anyone over the edge. She was surprised he hasn't been taken over by Satan a second time. He was the perfect example of someone who could become possessed.

For some reason she wanted to help him, she wanted to earn his trust. When she thought about him dealing with his demon side all on his own, whether intentionally or not, it made her heart clench in her chest. Maybe it was because he gave her his blood without even really knowing who she was.

She was suddenly pulled from her thoughts when the doors opened and Yukio started to get off. "We're here, let's go." His voice still had a hint of strain when he talked, but if you weren't listening for it, he would've sounded like his usual self.

Since she didn't know the layout of the city, or where anything was, Calista didn't have much choice, and was forced to follow him. Nodding her head, she quickly exits the train, hurrying to walk beside him.

Now that the truth was out, the tension between them was thick, so much more than it had been after she fed from him that night. For what felt like hours, but was only minutes, they were completely silent. The longer it went on, the more frustrating it started to become. Eventually, she couldn't take it anymore. "Alright, I can't take the silent treatment anymore. At least talk to me about the locations where the bodies had been found. Maybe something on the girls themselves, maybe I can figure out a way to draw the demon out."

At first, she didn't think he was going to answer her, remaining silent for several minutes longer. She was about to speak up again, when he finally glanced over towards her. "The bodies were found in a deserted alleyway the following morning. No one reported them missing and they were found by the homeless. Nothing was taken off of them, they still had all their money and possessions on their persons. There wasn't any physical signs of a fight, no markings whatsoever. They were completely drained of blood, but they can't figure out how the blood had been drained." He sighs and using his index finger, pushed his glasses back up his nose. "They were both females, roughly the same age. There isn't anything else that connects them. They were from different parts of the city, different occupations, though both were described as being beautiful."

As he explained the situation, Calista crosses her arms and nods her head, taking in every detail that she could. "Alright," Unfolding her arms, she starts counting them off with her fingers. "So they were the same age, female, pretty and completely drained of all their blood, but it's uncertain how." Letting her arms fall back to her sides, she gives another nod. "Well, it's safe to say that we're definitely dealing with a demon. Remember when I fed from you?" She glances up at him, just in time to see a faint blush color his cheeks, before he looked away.

"Yeah, what about it?"

"I told you that by morning the puncture marks would no longer be visible and would be completely healed. The reason being, is that there is something in my saliva that heals the wound so that it seems like it was never there to begin with. This makes it easier to take what I need and leave the human none the wiser. They think it was a dream and nothing more. Unfortunately, whoever is doing this isn't just taking what he needs. Also, it's safe to assume we're dealing with a male."

He looks down at her, a questioning look in his eyes. "Why a male? What makes you assume that?"

Calista looked up at him and smiled. "Would you bite the neck of another man or would you prefer one of a hot, young female?" She chuckles lightly, placing her arms behind her neck. "I personally go for the opposite sex, but if I have to, will feed from another girl."

Yukio turned his head so quickly that she wasn't able to read his expression, the light gleaming off his glasses didn't help either. "Yes, well, I suppose that makes sense." He goes silent once more, only to speak a moment later. "Alright, so we're searching for a male demon, anything else?"

"Well, he's likely to be a foreigner like me. Seeing as I'm the first vampiric demon you've encountered, it's safe to say that there aren't any in Japan and if there are, then they're rare and keeping themselves hidden. This one, seems to want to draw attention to himself. So it's likely we're walking into a trap. Don't let your guard down."

He nods his head, stopping as they come up to the opening of an alleyway. "This is the first location where one of the girls was found."

Moving into the alleyway, Calista looked around, trying to find anything that might possibly give her a clue as to who they were dealing with. It didn't take her long before she realized there just wasn't anything here. "Nothing," She sighs heavily in frustration. "Either our demon is very good at cover his tracks, or the police have already taken anything that might help us at all."

Since there wasn't nothing here, she makes her way back to Yukio's side, only to stop mid step as the hairs on the back of her neck stood straight. She looked at her partner, and without speaking a word, knew that he sensed it too.

They were being watched.

Well that was chapter 10, I hope you enjoyed it. I'm looking forward to bringing in our villain next chapter. Hopefully I'll continue my streak and having it out within the next couple days at the least. Remember to send in those reviews! Until next time~
