Alright, here's the next chapter. Sorry again if this one is once more a bit boring, but I'm working into it upping the drama and bringing in a fight scene soon. Not sure when I'll be able to get the next chapter out, so bare with me.

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

Calista's PoV

If the demon that killed those girls was in fact like her, than the best bet in finding him would be after sundown. Unlike in the movies, she could go out in the daylight, and it didn't have any ill effect on her. Come sundown though, she did become much stronger, especially after consuming human blood. So it was a safe to assume that the demon would come out either at dusk, or shortly after to feed. That's when she would go in search of him herself.

In the meantime, Calista decided to clean her weapons and focus her mind. She needed to make sure her mind was completely focused on the fight that was likely to take place. She didn't show her weapons often, but they needed a good cleaning. With the three pistols disassembled on the bed, she meticulously cleans them, making certain they were all in proper, working order. It had been a while since she carried all three of them, but tonight she wouldn't be going out as a student, but the full fledged Exorcist that she was.

Much like Yukio, Calista's weapons of choice were pistols, three of them to be exact. Unlike Yukio, she didn't prefer to carry them at the small of her back, instead she wore a shoulder holster that held her two main guns and a holster on her right thigh that held her back up. Between the three of them, she had a total of 73 rounds; not including the extra clips she carried on her side's for quick reload.

Her guns meant a lot to her, they were given to her by the woman who found her. Instead of killing her, she took her in, taught her how to control her vampiric urges. Just before Calista left Rome, she taken her out and bought her the Ruger LC9s that she now carried as her back up on her thigh. The twin Glock 19's had been a gift for becoming an Exorist. Needless to say, these guns meant everything to her.

It took most of the afternoon, but she was putting her last pistol back together as the sun began to set. Looking up towards the window, she watched as the sky changed colors, going from blue to a red/orange. It was a beautiful sunset. "Alright, time to get ready then."

Dressing in a pair of comfortable jeans, Calista first strapped on the thigh holster, making sure it sat comfortably before carrying on. Grabbing a white button up shirt, she left the first two button undone, the white tank top visible. With her shirt on, she opens her closet and pulls out the custom made shoulder holster out, carefully putting it on and making certain it was placed properly, so that it was both comfortable and not in the way. Both her thigh and shoulder holsters on, she puts on her magazine belt. This would allow her quick access to her clips, making it easy to reload her guns in the middle of battle.

Now that her holsters were in place, Calista checks over each of her guns one more time, adding their clips and pulls back the slide, a single bullet being loaded into the chamber. With the safety in place, she holsters the gun. She does this with her two other pistols, making sure each weapon had a bullet in the chamber and was ready, before switching on the safety and adding them to their proper holsters.

Since se couldn't reveal that she was actually here to spy on the twins, she couldn't wear her normal True Cross coat that would conceal her weapons. Instead, she brought along a black trench coat that would have to suffice until she could let her secret out. Thankfully this coat wasn't heavy or cumbersome and would serve it purpose, hiding her guns from the public.

Dressed and ready for a fight, Calista snaps her fingers. When she did this Cerberus immediately woke up from his nap and moved to stand by his master's side. Laying a hand upon the hellhounds head, she spoke without looking at him. "Let's make sure we take care of this bastard before he manages to kill anyone else. We're on our own tonight, so I'm counting on you to watch my back."

She felt his nod his head once. "I will make certain no harm comes to you. We have a contract, after all."

"Good, now let's get on with this before either of them catches on to what we're planning. At this time, they should be in the kitchen eating. Be quiet and try not make them aware of us leaving. It'll only make Yukio more suspicious." Again, the hound gives a nod, though this time he didn't comment.

While they still had the chance to leave without being noticed, she opens the door to her room and exits, Cerberus close behind her, waiting as she silently closes the door. Looking left to right, she makes sure the coast was clear before continuing to the stairs and out the front door. Now that she was outside, she gives a sigh of relief, tilting her head down to Cerberus. "This would be so much easier if I'd been able to scout out our surroundings prior to this. I have no idea where I'm going or where the locations of the bodies were found."" This time when she sighs, it was one of frustration. "We're in foreign territories here with no directions."

"I did tell you to try and recruit the Okumura boy to help us." He said, tilting his head to the side a bit, his red eyes looking up at her.

"It's not like I didn't try." She shrugs her shoulder, taking off in a run, heading towards the train that would take her into the main city of Tokyo. "When I tried to tell Rin what was going on, Yukio stopped me. If I'd enlisted his help, I wouldn't have had to go about this alone, but no, Four-eyes just had to step in." Rolling her eyes, she ran as quickly as she could, planning to ride the train from the roof, rather than take her hellhound on the train.

When she arrived at the station, she noticed that they were too early, the train wasn't even here yet. She was a bit out of breath, panting heavily as she tried to catch her breath, Calista looked both ways down the track. "Damn, it doesn't look like it's going to be here any time soon." Pulling the summoning paper out of her coat pocket, she holds it between her fingers. "I'll summon you once I'm in the city." She doing wait for him to protest, ripping the paper in two and breaking the circle. Being a Tamer as well as a Dragoon, Calista could easily summon her demon familiar once more.

With the summoning paper torn, Carberus immediately disappeared in a puff of black smoke. She hated having to do that, and would likely hear about it later when she brought him back, but with the train appearing to be late, she wouldn't be able to jump on like she planned to do earlier and instead needed to wait for it to arrive. "This is such a pain..."

"It's only a pain because you ran off on your own."

"That voice..." Quickly, she snaps her head to the side, looking behind her, watching as a dark figure approached her from the shadows. "I thought I left without you noticing." Her surprise was evident in her voice.

The light gleamed as he pushed his glasses back into place. "I figured you would do something reckless like this after leaving the way you did this morning, so I decided to keep an extra close eye on you throughout the day." Yukio stepped into the light of the station, wearing his True Cross Order uniform.

"Damnit..." She didn't even realize that she was being watched, much less being followed. Though, now that he was here, she knew there wasn't any reason to argue with him, knowing that he wouldn't listen to her anyways. Pinching the bridge of her nose, she looks at him. "Fine, but you better be here to help me. I'm not going to have you hovering over my shoulders because you think I'm a threat."

"I wouldn't see you as a treat if you would just come clean about your true reasons in being here." His teal eyes narrowed, glaring at her from behind his glasses. "I know you're hiding at least two guns beneath that coat of yours, and students aren't issued those type of holy weapons just yet."

He really had been watching her, and she underestimated him, thinking she'd been keeping herself secluded enough to go unnoticed. Right now, he had her backed into a corner. Unless she gave him the truth, he would continue to suspect her and that would but innocent in danger, as well as herself.

"Fine," As she started to speak, the train's horn blarred, announcing it's arrival. Even though it was coming to a stop, it still kicked up enough wind to blow open her coat, revealing her guns, even moving her hair around her face. "I wasn't transferred here as a student. I'm an Exorcist First Class. The Vatican sent me here to make sure Satan's powers were kept under control."

The surprise on his face was something she expected, but the betrayal she saw, wasn't. "That's ridiculous! Rin has more control over his flam-!"

"It's not Rin I'm here for," She quickly cuts him off. "You're the one who's under surveillance, Yukio. If I get even the slightest hint that you're a treat, I've been given the order to terminate you, as well as your brother."

His eyes went wide. Those beautiful teal eyes, widened in absolute shock. "Tha...That's impossible..."
