I don't know Blue Exorcist/Ao no Exorcist
I only claim those created for this story

Calista's PoV

Blue eyes looked back over his shoulder, narrowed on her as she sat on the ground trying desperately to catch her breath. Her throat hurt to touch, but she knew come morning, it would be as if nothing ever happened. "R-Rin…" She winced as she tried to talk, his name only coming out as a hoarse squeak.

"Just shut it," He said, turning his attention back to the demon. She could see now that he was cradling his arm against his chest, and while the limp wasn't completely severed, it wasn't all the way on either. "After I've kicked his ass, you and Yukio can explain everything." With a yell, he rushes forward to engage the enemy.

From the ground, she watched as the oldest twin fought back against the vampire. Still, the vampire was strong and dodged or countered each swing of the sword, even injured as he was. Though, it seemed he was on the offensive, doing his best to keep away from those blue flames.

"Calista!" Someone yelled her name.

"H-huh…" She turned her head in time to see Yukio running up beside her, skidding in the dirt, his gun still in his hand. "Yu-"

"Don't talk," He immediately cut her off. Putting his gun in the holster at his back, he reached out his hands, touching her neck. Whereas the vampire had been forceful, cutting off her airway, Yukio's hands were gentle and warm, looking over her injury. She'd forgotten he was also a doctor. "Are you alright?"

Was that actual concern in his voice? She quickly dismisses the thought and nods her head. Since it hurt too much to talk, and Yukio told her not to do so anyways. His eyes looked her over, his hand touching her throat and seeming to pay close attention to the spot where the vampire had nearly bitten her. The way he touched her, made it seem like he might actually care whether or not she'd been hurt.

Bringing her hands up, she grabs a hold of his wrists. When he paused and looked at her, she shook her head, pushing his hands away with a small smile. "I'm alright, Yukio, go and help Rin." Calista says in a soft voice, even though it caused her discomfort to say anything.

He looked at her a moment more, and she could now see that the right lens of his glasses were cracked. The concern fades from his eyes and as they narrowed, anger flared up in their depths. The teal coloring darkened and took on a more blue tint, comparable to Rin's. "Right, just stay here." Getting back to his feet, Yukio takes off to help his brother, his hands disappearing behind his back just long enough to pull the pistols from their holsters.

Calista watched Yukio rush off to stand beside his brother. Together the twins worked to corner the demon. Shots rang out, echoing off the building walls. Blue flames lit up the entire area, casting a blue light over everything. Even though Yukio played it off like he wasn't overly fond of his brother, the two of them worked together better than most. They didn't need to speak to each other, reading the others movements and body language. Yukio knew when he would throw his flames and Rin knew when to jump out of the way of Yukio's bullets. It was actually really incredible to watch.

As she watched the two of them fighting side by side, Calista began to feel weak compared to them. Looking around, she tried to spot her familiar. "Where the hell are you, Cerberus?" She questioned, worried about the hound. He'd been ahead of them, and it was possible that the vampire had injured him before they were able to catch up.

Her hands curled up in her lap. She couldn't just sit here and do nothing, while the twins were fighting. Deciding that she wouldn't just stand by, Calista spotted her guns. Grabbing them both, she gets to her feet, planning to join Yukio and Rin. Her knees shook, whether from fear or still not at 100% after being choked, she didn't know for sure. Either way, she wasn't the type to let others fight her battles. With the three of them working together, they should be able to quickly over power and defeat him.

Unfortunately, by the time she gained her courage, the sounds of gunfire ceased and the bright glow of blue flames disappeared, casting the area in darkness once more. Was the fight over? Did the Okumura brothers defeat the demon? Turning her head side to side, she looks for the twins, finding them on the other side of the empty lot, speaking to each other.

Holstering her guns, she runs over to them. "What happened? Did you beat him?" She calls out.

Yukio looked back over his shoulder at her, his eyes once more that beautiful shade of teal. "No."

"The damn coward took off." Rin spoke up, his sheathed blade over his right shoulder. "He didn't even try to attack back, defending himself and then running off."

Hearing that he got away, a chill went down her spine and she felt the blood drain from her face. Her knees suddenly give out and she falls to the ground. Calista expected to hit the ground hard, but instead she felt a pair of arms wrapping around her, catching her before she met the hard surface.

Fear. There was no doubt about it now, this was fear. She was terrified of this strange demon, of how much he knew about her. Her vision began to tunnel, as the fear overwhelmed her. Before she could even attempt to fight against it, she completely blacked out.

Yukio's PoV

From across the bedroom, Yukio stood with his back against the wall, his arms folded over his chest. His coat lay over the back of Calista's chair, thrown there haphazardly, forgotten in the moment. The room had no lights on, but Yukio could see perfectly; watching as the female rested in the bed just feet from him.

Given the circumstances, some might think he was here just keeping an eye on her, having admitted to being a spy for the Vatican. This wasn't the case. Instead of watching over her for being a spy, Yukio stood watch over her, worried about her health. After she blacked out, Rin had offered to carry her back to the dorms, but Yukio wouldn't allow his brother to do so, taking it upon himself to take her back, to see over her and tend to her injuries.

His glasses began to slip down his nose. Normally he would immediately push them back into place, but his entire focus was on Calista. While her breathing was no longer ragged and labored, and the bruising on her throat was fading, she still hasn't woken up. It's been hours now, and the morning's first light would soon shine through the window.

He had a class to teach this afternoon, and his own classes this morning. Still, he didn't want to leave her like this and she suddenly take a turn for the worse. With his jaw clenched, Yukio takes a step towards her, finally adjusting his glasses. Standing beside her, he looks directly down, looking her over. Her color looked good, she showed signs that she wouldn't fully recover. If she had healing properties like he and Rin did, than by tomorrow she should be back to her old self.

Sighing heavily, he sits down on the floor beside the bed. Exhausted after fighting against the demon, then staying up all night watching over her, he could feel his eyes were heavy. Using his arm to prop his head up, Yukio rested his head, closing his eyes. He'll close his eyes for a few minutes, just long enough to recollect his thoughts. Then he'll have to leave her to get ready for school; coming back to check on her every chance he got.

"Yukio.." He could hear someone calling his name. "Wake up, Yukio." Along with his name being called, Yukio felt someone gently shaking his shoulder.

When he opened his eyes, Yukio blinked a couple time. Only, no amount of blinking would chase away the blurriness of the room (Does anyone know just how bad Yukio's eye-sight really is?). Scowling, he lifts his head, flinching at the stiffness of his neck and back. How long had he been out? "Where are my-"

"Here," He was cut off by a soft voice coming from his right. "You looked exhausted and I figured your glasses weren't very comfortable to sleep in, so I took them off."

He could make out his glasses being held out for him, and taking them he put them on, instantly clearing his vision and allowing him to see once more. Looking around, he realizes that he was still in Calista's room, sitting on the floor where he sat down moments ago. He frowns, taking note the light filtering in from the window.

It was too bright to be early morning...

"What time is it?" He asks, sitting straighter and stretching his stiff back. "How long was I out?"

"It's close to two in the afternoon." His eyes widened as she said this. "I woke up about an hour ago. When I saw you sleeping, you looked so peaceful that I thought to just leave you alone."Her words trailed off, soon falling on deaf ears.

He was so late! Yukio quickly jumps to his feet, stumbling a bit his feet tingling and numb from sitting on the floor for so long. He jumps around trying to gain feeling again, grabbing for his jacket, instead it get caught on something and as he goes to pull back on it, the chair tips over. With his feet tingling as they were, he couldn't keep his balance and ends up falling over.

From the bed he could hear her muffled laughter. Looking over at her, he shoots her a deadly glare...which did nothing to make her stop laughing at him. Rolling his eyes, he gets back to his feet, the feeling in his feet finally back enough to allow him to stand without feeling like he was standing on pins and needles. "Shut it," He forcefully pulls on his jacket, embarrassed now. "I completely skipped classes today and I'm due to teach as well. I was only suppose to close my eyes for a few minutes." Yukio was mostly mumbling to himself now, annoyed that he over slept.

"Calm down," Calista said, now sitting on the edge of the bed with her feet touching the floor. "Last night was hectic, it's no wonder you were exhausted. You obviously needed the sleep or you wouldn't of fallen asleep like you did." She shrugs her shoulders, standing up and stretching her arms above her head. She only wore her shirt and jeans, Yukio removing her jacket and gun holster when he brought her back. "Especially since you were able to fall asleep in such an awkward position."

Seeing her stretching, Yukio slowed down a bit. Instead of putting his jacket on with force, he now pulled it on more easily. Mostly because he was taking in her appearance and health. "How are you feeling? You passed out after the fight last night."

She looked over at him. "I feel fine, actually. I'm pretty sure that I'm all healed up." Tilting her head a little, she looks at him questioningly. "Yukio, why did you stay here with me all night?"

He looks away, hiding the blush that he felt creeping up to his cheeks. "I wanted to make sure you were alright. That you didn't take a turn for the worse in the middle of the night."

"I didn't think you'd really care."

His head turns quickly towards her. "What? Why the hell would you think that? Of course I'd care." Shaking his head he goes to the door, pausing just a moment to look back at her. "No worry about coming to classes today, just stay and get some rest. You're looking a little pale again." After giving her his orders, Yukio leaves her room, closing the door behind him.

Not sure how I feel about this chapter. I like it and I don't at the same time. The enemy is still on the loose. What will that mean for Calista? Just how much does he actually know about her, and what are his plans? Yukio seems to be coming around, openly admitted he cares. Remember to send in those reviews!
Until next time~
