Sorry for not updating sooner, I've been busy or just haven't felt like writing. I enjoy this fanfiction and I have some future plans, but I gotta say, I'm getting a little discouraged. I hope you're all enjoying it as well and would love to hear your thoughts and anything you'd like to see happen.

I don't own Blue Exorcist/Ao no Exorcist

I only claim the ocs created for the purpose of this story

Calist's PoV

"His blood..." Calista retreated to her room rather quickly. After that night with Yukio, she had a hard time looking at him without her face turning a bright crimson. It's been days since she drink from him, and still it felt like there was fire coursing through her veins. Was it because he was half demon like her? Or maybe it was because he was Satan's son.

Since that night, she couldn't help seeing him in a different light. Even though he was straight forward and strict, he was sometimes willing to break the rules. He could have easily turned her over to the Order (not that it would have done much good), but instead he offered his own blood to help her. She couldn't hate him for that and in fact was in his debt.

Sitting on her bed, with her back against the wall, Calista closes her eyes, sighing softly to herself, hoping it would clear her mind. When she closed her eyes, the exact opposite happened. Her thoughts didn't clear, instead they shifted back to Yukio. The way his blood tasted on her tongue; spicy but at the same time sweet. It wasn't just the way his blood tasted on her tongue, but the way his scent invaded her senses and made her head spin. The taste of his blood, combined with his scent...she practically melted in his arms.

She was surprised when she heard the softest of moans slip from her throat. So much so, that she opened her eyes wide, her spine stiffening. Grabbing a hold of the sides of her head, Calista shakes it repeatedly. "No, no, no!" She could not begin to feel anything towards Yukio Okumura! Not even a silly crush!

A knock on her door ripped her from her thoughts and she jerked her head up in time to see Rin entering her room, peeking his head around the wall. "Hey, your door was opened a bit so I let myself in. Hope you don't mind."

Clearing her throat, she shakes her head and scoots to the edge of her bed. "I don't. Sorry I was daydreaming a bit and didn't hear you come in."

"No worries, I just wanted to stop in and see if I could borrow your notes from class today." He grins, rubbing the back of his neck. "I kinda fell asleep again and didn't get them all." He chuckles lightly.

She looks at him a moment, staring blankly. "How in the hell has he even made it this far?" She imagined it was just by pure luck, or raw talent. It definitely wasn't because of his studying skills."Yeah sure, let me get them." Getting to her feet, Calista walks over to the desk where her backpack rested on the end of her chair. As she digs through her things, she glances back at him, only to notice he was looking at her things. "If you're going to gawk at a girls stuff, try not to be so obvious."

His eyes went wide, and his face turned red. "I...I u-uh..." Rin crossed his arms and turned his face away, avoiding looking at her and her things. "I wasn't gawking!" He yelled at her, glaring, but she could tell he was embarrassed having been caught.

She laughs out loud, grabbing the papers he needed and handed them over to him. "Don't sweat it, there isn't anything here that I'm worried about you seeing. That stuff I keep hidden away.~" She laughs again at the look on his face as she mentioned this. "You're really easy to pick at, you know!"

"Hey! Cut it out!" He takes the papers from her hand, looking them over a second. "Thanks, Yukio can be a pain in the ass if I don't do any kind of studying." Taking her papers, he turns to leave, but pauses just before exiting her room. "You know, you look a lot better lately."

Her eyes widened. "H-Huh?! What are you talking about?" Now it was her turn to be the aggressive one.

Rin holds his hands up defensively. "I didn't mean anything by it, just that you're looking better than you did when you first got here. I guess you're adjusting quickly." He lifts a hand and waves, leaving her room. "Thanks again!"

Once he was gone, Calista goes to the door and looks out, watching as the oldest Okumura brother walks down the hallway, back towards his own room; his ever present sword on his right shoulder. His words lingered in her mind as she watched him leaving. The fact that she looked better, meant that Yukio's blood had done the job, bringing her back to full health. He didn't mention his brother, or the blood she drank from him, which likely meant Yukio hasn't said anything to his twin.

She sighs, speaking out loud, "Thank God..."

"For what?" Her eyes widened and she spins around to face the familiar voice behind her. How did she not realize he was there?! Immediately, her face turned red and her throat dried up. There must've been something in her expression that worried him, because he suddenly got a look of concern in his teal eyes. "Hey, are you alright?" He asked, taking a step towards her.

As he took a step forward, Calista quickly took a step back, bumping into the door frame. "Y-yeah! I'm fine!" She gains her composure back, recovering the step that she'd taken, holding a fist out to him. "Don't sneak up on me like that! You scared the hell out of me!" Crossing her arms, she puffs out her cheeks, pouting frustratedly.

Yukio gave her a sheepish smile, lifting a hand and rubbing the back of his neck, much like Rin had done just moments ago inside of her room. Even though the two of them weren't identical twins and shared very little in common, there were some gestures that resembled one another and this was one of them. "Heh, sorry about that, but I wasn't exactly trying to sneak up on you." Letting his hand fall back to his side, he looked at her once more with concern. "Are you really okay? Last time you said that, you weren't at all fine. If you nee-."

Calista hurriedly cuts him off, "I don't, and I'm fine, really…" Her arms fall to her sides, bringing her left hand up, she crossed it over her chest and grabbed her right bicep. "I don't need anymore, and from the feeling of it, I won't for a while." She still didn't know what it was about his blood, but she felt like she could easily go a month without needing another drop.

He sighs with relief. "That's great, I'm glad to hear it." There was then a long pause before he speaks again. "If you ever need more…" Another pause, accompanied by a faint, pink, tinting of his cheeks. "Don't be afraid to come to me for help." He says the rest of his statement very quickly, pushing his glasses up his nose again; only this time it seemed to be a reaction made from nervousness, rather than his glasses uncomfortably slipping down his nose.

"He's kinda cute when he does that.." Her thoughts trailed off. Quickly, she shakes her head, and the unwelcome thoughts, from her mind; answering him. "I appreciate your help, Mr. Okumura."

"Yukio…" he said, "Call me Yukio. There's no need to be so formal."

She looked up at him for a moment. "I shouldn't get too close…" Eventually she smiles and nods her head. "Alright, Yukio. Thank you again."He nodded his head, walking passed her, following his older brother. Calista stood there a while more, watching his back as he walked away. "Keep your distance…"

But she didn't think she'd be able to take her own advice.

So this is I think my shortest chapter, but I wrote most of it while I took my breaks at work. I have these next two days off, and hope to update again within these two days as long as nothing comes up. Please send in those reviews and let me know if you're enjoying or if you're not, and if not how you feel it could be improved!
