Hey all. Sorry for not updating recently. I've been working and it's been an exhausting couple days. So here's the new chapter, I hope you're all enjoying it so far; I know the first two chapters have been a little slow to start, but all good stories start out slow before picking up. I'm going to try and start getting into the main plot and explaining a little about Calista's origins. After that, I'm hoping to get to building the chemistry between our main pairings. :3 Now I'm not going to waste your time any longer, on to the story.

I do not own Blue Exorcist in any way, I only claim the oc's created for this fanfiction.

Calista's PoV

The first class mission came in three days later. For the most part, she'd been able to avoid Yukio and Rin, only seeing them at meal times and during cram classes. She found out that Yukio was just one of their teachers and that there were several others, including swordplay; something she wasn't exactly good at, relying mostly on her hellhound and the pistol she keep hidden on her upper thigh, just underneath her skirt. Normally she had her weapons within easy reach on her side's, using a shoulder holster to carry her pistols, but she wasn't suppose to be anything more than a normal student and normal student don't yet carry weapons like hers.

Their mission was to take place in the middle of the night. Apparently there has been complaints of unknown mischief going on. From the sounds of it, the demons involved were nothing more than low level goblins. For her, this mission would be a piece of cake.

Yukio broke them up into groups of two. She'd been assigned to go with some girl named Shiemi who had a little greenman as a familiar. One thing Calista instantly noticed about her was just how shy and nervous she was. She didn't talk much, outside of asking which way they should take. As soon as they were away from Yukio and the red headed boob girl, she planned on ditching her partner and going out on her own. Goblins were nothing.

It didn't take much to lose Shiemi, ordering Cerberus to run off ahead of her, making it seem like she had to chase the hound down, calling out to him. Couple turns, and she had lost her. Crossing her arms, she leaned back against the wall of a building, sighing heavily in annoyance.

"This sucks…I'm a full fledged Exorcist, pretending to be an unskilled newbie. It's a disgrace to my skills." She complained.

"When are you going to take my advice, and feed yourself? The longer you go, the weaker your body becomes. You're not at your full strength. How do you plan to take on the demon twins when right now you're neglecting your own needs." Cerberus growled at her, snapping his jaws, demonstrating his frustration.

Calista glared down at him. "Would you shut it already. I'm fine and I don't need you reminding me." She pushed off the wall and head down the alleyway.

Of course Cerberus follows her. "If you're not going to look out for yourself, someone has to."

Though, he had a point. She'd gone several days at this point without properly feeding herself. If she went any longer, she was likely to get herself hurt, or someone else. "I'll deal with it after we're through here. I can't let anyone catch me, so I'll go out again after everyone's gone to bed. Is that alright with you?"

He nods his head. "That will suffice."

Nodding her head, Calista sighed and placed her hands behind her back where she clasps them together. She didn't intend to do any of the goblin hunting that the mission called for, but instead she found a rusted old ladder and began climbing up towards the house roofs. At this height, she'd be able to keep a an eye on things that were going on below. It was easy enough going from rooftop to rooftop, her demon blood allowing her to do things that most humans couldn't and right at her side, Cerberus followed obediently.

When she found a few of the students, she was careful to go unseen as she followed them. Her turquoise eyes showed her amusement at watching them handling any demons they encountered. Honestly, she had to hand it to them, they were decent. At the rate they were going, they would all easily make full fledged Exorcists in no time at all. Even though she paid attention to the human students, she kept a close eye on the oldest of the Okumura brothers, waiting and wondering if he would pull the demon sword from it's sheath, igniting those blue flames. From the reports she read prior to coming here, Rin relied heavily on his demon powers tied to the sheathed sword in his hand. It was only a matter of time before he pulled it, for a bunch of low level hobgoblins.

"Eventually he's going to mess up…I know it." Calista thought to herself as she watched from the roof of the building.

For a moment, she turns her attention away from the older twin, searching for the younger of the two. It took her longer to find him. It seemed he decided to stick back and watch how is students did on their own. From this height, she was able to watch him without him having his guard up; on his own, he let his emotions slip through.

There was noticeable tension in his jaw; something was causing him quite a bit of stress. She knew that it couldn't be his brother, seeing as he was off with his partner exorcising any demons that crossed their path, so what could it possibly be? She got her answer when his left arm suddenly caught fire. Her eyes widened at the sight of those infamous blue flames and at the same time, she realized that he was struggling to maintain control of them. Unlike his cool, calm, exterior, Yukio fought to keep his flames in check.

"This is interesting," she thought to herself, a light smirk on her lips. "It would appear Mr. Collected, isn't quite collected after all."

While she watched Yukio, her thoughts distracted, Calista let her guard falter. Behind her a large and unusually strong goblin appeared out of thin air; going unnoticed until it was too late.

"Calista, behind you!" Cerberus called out to her, immediately going on the defensive and attacking the demon.

Hearing her familiar's warning, she began turning around to defend and attack, but before she could pull any weapons, the Behemoth lunged at her; her hellhound had his jaws firmly attached to his arm. "Shit…!" Being the on the edge of the building, she had little room to maneuver and couldn't get out of the way quick enough. As the demon lunged, she took a step back, only to feel her foot slip on the edge. Her eyes widened as she felt her foot slip and suddenly she was falling from the roof of a three-story building. There wasn't a lot in this world that terrified her, but at the top of her list, falling was the most terrifying.

A gasp of fear was pulled from her throat, the air in her lungs rushing out. She could feel the "weightlessness" of her body rushing towards the ground below, her stomach in her chest. Even though she was half demon, a fall from this height, would leave her seriously injured. Closing her eyes tightly, she braced herself for the pain that she knew would be coming.

Yukio'S PoV

Somewhere above him, Yukio heard someone calling out a warning. The voice was in his head, one that no one without demon blood would be able to hear. "What the...?" He questioned out loud, tilting his head up to try and see who it was. His eyes widened though, when he saw a girl falling from the roof of the building above him.

He didn't have time to think about it, his body reacting before he even got the chance. Eyes narrowing, he put out the flames that had engulfed his left arm and leapt towards the falling girl. At the same time that he caught her against his body, wrapping an arm around her to keep her secure, he pulled one of the two guns from the holster at his back. Taking aim at the large Behemoth goblin coming towards him. At the last second, he realized that there was a hellhound attacked to it's arm. Readjusting his aim, he fires two rounds, hitting the demon right between the eyes, effectively killing it.

With the demon dead, Yukio landed back on the ground, looking down at the girl he'd caught; realizing then that it was his new student. "What the hell was she doing up there on her own?!" Just as he was about to voice his question out loud, he noticed her eyes were shut tight and her face was paler than usual, making it easy to tell she had been terrified.

Taking a deep breath to calm himself, Yukio careful let her feet touch solid ground. "You're safe now..." When he felt she had her balance, he let her go fully. "What were you doing up there on your own? I thought I assigned you and Shiemi to work together as a team?"

Even though she was now safe on the ground, Yukio could see that she was still shaking. Did she have a fear of heights? Still, she pulls herself together rather quickly, turning and looking up at him, only to look away once more, avoiding eye contact with him. "Yeah well, Cerberus ran off and I had to chase after him. At some point, Shiemi and I got separated and I climbed to the roof to see if I could find everyone quicker than looking on the ground." He listened to her explanation, noticing her cheeks darkening as she blushed in embarrassment. "That demon caught me off guard and my foot slipped off the edge."

An accident then...

Sighing, Yukio using his finger to push up his glasses, keeping them from slipping down his nose. "Fine, but you should learn to control your familiar a little better. If this was a real battle and he had run off, separating you from the group, you could have been seriously injured by a more powerful demon."

Calista too sighs, but she seems to accept his chastising with a simple nod. "Yeah, alright, it won't happen again." He watched her pull out the summoning paper from her vest pocket, holding it between her fingers and tearing the sheet, releasing the hellhound. "If it's alright with you, I'm going to head back to the dorm. That fall left me a little shaken..."

He found it a little odd that she refused to make eye contact with him. Maybe she was just too embarrassed for making such a mistake. "Alright fine, you're dismissed for the night. Let this be a lesson to always stay aware of your surroundings."

She nods her head once more, but doesn't say again. When she turned around to leave, something caught his eyes. Were those...? His eyes had gone wide. Her ears...they were pointed! He was certain of it. It had been brief, but he HAD seen them underneath her hair when she turned. Did that mean she was half demon too? Was that why she'd been sent here? Shaking his head, he brushes the thought aside. No, it was just a coincidence.

He watched her leave until she was completely out of sight. Only then did he turn his full attention back on his other students. It didn't take them longer, clearing out the goblins quickly on their own. While there had been some mistakes, they had all performed really well. Calling it a night, Yukio and Rin head back to the dorms together. Rin going on and on as usually, but he couldn't get the new girl out of his thoughts. For days now she's been invading his waking mind. Who was she and why was she here? Seeing what he thought were demon ears on her tonight, only increased his curiosity.

Yukio and Rin arrived back at the dorms around an hour after Calista left. "Man I'm hungry!" Rin complained. "I'm going to the kitchen right now making a bowl of-" A window broke from the second floor, cutting Rin off.

"What the hell?!" Yukio didn't hesitate, running inside, pulling both of his guns as he and Rin rush inside. Did a demon get inside? "Calista!" He calls out to their new dorm mate, after tonight's incident, he worried that she wouldn't be able to handle a higher level demon on her own. Rounding the staircase, he takes them two steps at a time, knowing Rin was right on his heels, ready to pull his sword at a moments notice.

"Calista!" He calls out to her again as he comes up to the second floor.

The entire landing was covered in darkness, not one light on. He couldn't really see anything. Turning his head left and right, he tried to listen for anything that could indicate that there was a threat and where it was. When he turned his head to the left though, Yukio froze. At the end of the hallway, a pair of glowing crimson eyes stood out, glaring at him and his brother.

Hope you enjoy this chapter, took a little longer than I expected, but as stated above, I've been fairly busy. Remember to send in those reviews!
