I do not own Blue Exorcist/Ao no Exorcist in any way.
I only claim the oc's created for this fanfiction.

"What the hell is that?!" Rin yelled out, holding the demon sword in both of his hands, getting ready to pull it from it's sheath if he needed to.

"I have no idea, but keep your guard up." Yukio said to his brother, moving the guns forward, aiming at the pair of crimson eyes.

Whatever was at the end of the hallway, took a step toward them, a low growl emitting from its throat. It was then that both Yukio and Rin heard a voice speaking to them. "Put your weapons away."

"Reveal yourself!" Yukio yelled out to it. Seeing as he could hear the voice in his head, but not out loud, he made the assumption that whatever this was, it was some kind of demon.

It growls again, this time barking. Wait…barking? While the dorm building was completely dark, the moon outside was full, and as the clouds moved from in front of it, light shined through the windows, illuminating the darkened hallway. His eyes quickly adjusts to the changes in lighting and he sighs in annoyance as he sees who was at the end of the hallway. It was Calista's hellhound familiar, Cerberus.

Lowering his guns, but not holstering them, Yukio approaches the beast. "What the hell is going on here? Why are the lights out in the building and why did the window break?"

The creature didn't say anything more, instead he turns around and heads into Calista's room, the door wide open. Yukio glances back at Rin, who shrugged his shoulders, just as confused as he was. Since there didn't appear to be any threats in the building, Yukio places the guns back in the holsters at his back. He still wanted answers though, and so he follows Cerberus into the room, pausing just outside to address his brother. "Why don't you go down and check the breakers? Maybe they were overloaded and this is all just an odd coincidence."

"If that's the case, why are you following her demon into her room?" Rin asked, placing the sword back on his shoulder, glarring annoyingly at his younger brother.

"Because there's still the case of the broken window. I'm going to see if she's got any answers, if there's any problems I'll call you right away."

Rin stood there stubbornly, "Tch, whatever." He growls, turning around and heading back down the stairs and to the basement where the breakers were located.

Sighing at his brothers stubbornness, Yukio shakes his head. Facing the opened door once more, he politely knocks before entering. "Calista?" He called to her, much like he had as he raced up the stairs, though this time his voice was calmer, no longer thinking one of his students were in danger. Coming into the room, as with the rest of the building, the lights were out, the light from the full moon outside allowed him to walk without bumping into anything.

At first, he didn't see her anywhere, but the closer he looked the easier it became to see in the low lighting. Her room was mostly bare, with random pictures and posters hanging on the walls. There were still a few boxes left unpacked. Turning his attention away from her personal objects, Yukio looked around for her again. His eyes landed on the hellhound sitting in the corner. "Where is she?"

His lips pulled back from his teeth, and he growled much like he did in the hallway. Only this time, he didn't give him the silent treatment. "Get out, Son of Satan. We do not require your presence."

"Wait, how did he know that?" Yukio's eyes narrowed again, something was up with this pair, he just knew it. "I'll ask you only once more," Reaching behind him, he pulls a gun from the holster, aiming it at the growling beast. "Where's your master?" His voice was stern, the moonlight gleaming off his glasses.

"Why you little..." His growl deepens and he stands on all four paws, lowering his body as if readying to attack.

"Cut it out, Cerberus..." Calista's voice spoke up from behind him. "Stop trying to protect me all the time."

There was something about her voice; it sounded strained. Yukio looked over his shoulder, his eyes narrowing when he saw her crawling out from underneath the bed. She looked like hell...What was going on here? While she'd been pale earlier, he shrugged it off as her fear from falling off the roof, but now it appeared that there was an underlying cause. Narrowing his eyes, and tensing his jaw, Yukio walked over to hold out a hand to her, offering to help her up. "I think it's time you answer my questions."

She lifted her head to look at his outstretched hand, though she still avoided eye contact with him. "Yeah..." Taking his hand, she accepted his offer for help.

When she was sitting on her bed, Yukio took in her outward appearance a little better, or as best as he could in this low light. Grabbing the chair at her desk, he takes a seat in front of her. "Alright, let's start with why you're really here." As he questioned her, his eyes scanned over her. Not only was she pale, but her skin seemed sunken in. Her breathing was a little labored, like she was having trouble, or that the simple movement from the floor to her bed had taken a lot out of her. Either way, she was struggling. He could see that her hands were clasped together tightly on her lap, and even though it was subtle, he could tell they were shaking.

"The Vatican sent me here...to finish my training as an Exorcist..." She takes a deep breath, her voice just as strained as a moment ago, each word she spoke seemed harder to get out than the first. "Also...They didn't want a half..." She paused, her hands clenching together even tighter. "They didn't want to continue housing a half-demon."

"I knew it." His assumption had been right, those were demon ears he saw underneath her hair. "I see..." Was this really the truth? The whole truth? He couldn't tell for sure, her shaking hands would have normally given it away that she was lying, but he didn't suspect that her shaking was from not telling the truth. There seemed to be something wrong with her health wise. "Now, about your health."

"I'm fine." She quickly retorted.

"You're not." He glared at her. "You're pale and shaking. Your voice is strained. It's obvious that you're not okay. Stop acting all tough and stubborn."

"I told you I'm alright!" She yelled looking up at him, and this time he caught a look at her eyes. They were no longer the light shade of turquoise, but tinted with crimson. This caught him off guard, his own eyes widening, seeing the sharpened fangs in her mouth as she yelled.

Yukio quickly gained his composure, his hands clenching into tight fists, she was acting a lot like Rin. "You're obviously not! Suck it up and let someone help you, damnit!" If she was going to act like his brother, than he was going to treat her the same way. "Quit acting like a brat!"

"I'm not acting like a brat!" She stands up, surprising him with how fast she could move in her condition. "I'm trying to prote-" Her words were cut off when the lights suddenly turned back on. Tilting her head down, her bangs shadowing her eyes. "Just leave me alone, alright?" Her voice softened up and she walked past him, grabbing a towel and a change of clothes.

He watched her as she leaves the room. She was just as stubborn as his brother. Shaking his head, Yukio pinched the bridge of his nose, pushing his glasses up, sighing in frustration. "She's just as bad..." He whispered to himself. "I have enough trouble babysitting Rin..."

"She doesn't need babysitting." A voice behind him said.

"Huh?" He'd completely forgotten that Cerberus was still in the room. Turning around in the chair, he looked at the demon hound. "What are you talking about, she's obviously just as bad as my brother in temperament."

His rolled his crimson eyes, circling the spot in the corner, before laying down. "She's just hungry. This is the longest she gone without properly feeding herself. If she doesn't get a grip soon and do what needs to be done, her body will eventually force her to do so."

Yukio had no idea what he was talking about, he'd seen her eating at every single meal. "How can she be hungry? She eats with us at every meal."

Cerberus lifted his head and looked at him, then looked at the door, only to look at him once more. "Fine, to keep her safe, I'll tell you."

Yukio listened closely. When he finally made it to the point, his teal eyes went wide with shock. "Y-you're kidding me?!"

Let me know what you think so far! Until the next chapter, my lovely readers!
