I don't own Blue Exorcist/Ao no Exorcist

I only claim the characters created for the purpose of this story.


Yukio's PoV

The hairs on the back of his neck were standing straight up and even though he couldn't see anyone, he instinctively knew that someone was watching them. After checking out the first scene where one of the girls had been found, he and Calista joined the crowd once more, making their way to the second scene. Only this time they were both on alert.

He glanced down at Calista, walking beside him, holding her hands behind her back. While she looked like she had her guard down, he could tell that she was looking around, trying to get a sense of where their stalker was. How could she possibly act so at ease when they were being followed by the same demon, who just days earlier, killed two women? Then again, she already proved herself to be an adept liar.

His eyes narrowed behind his glasses and he felt his hands involuntarily clench into two tight fists at his sides.

She lied to him and to everyone. Pretending to be just a normal student, when in reality she had been sent by the Vatican to spy on him and his brother. What he couldn't understand, was why this bothered him so damn much! This wasn't the first time someone infiltrated his class and pretended to be one of his students. Shura Kirigakure spent weeks undercover as a male student, spying on Rin for the order. While he'd been pissed about the situation, it didn't even come close to how angry he was about Calista's betrayal.

Suddenly, he felt something or rather someone, flick his glasses, forcing them to go lopsided on his face. He then hears Calista laughing hysterically beside him, using her hand to cover her mouth. His eyebrow twitched, "What is so funny?" He asks, fixing his glasses.

"You had such a serious look on your face that I thought you needed a distraction." She tilts her head, looking up at him with laughter in her eyes. "Flicking your glasses made them go all lopsided, and now your expression is super cute!" She laughs again, doubling over as she did.

Yukio on the other hand, didn't find it as funny as she seemed to. He was just about to tell her to knock it off, when he caught the last part to her sentence. Cute? She thought he looked cute?

Turning his head away, he tries to hide the blush that crept up his neck to color his cheeks. This reaction took his by surprise, still he didn't want to let her see. "Yeah, well, cut it out, we're suppose to be looking for clues."

If she saw him blushing, Calista didn't say anything and after a couple seconds, Yukio was under control once more, with his usual stoic self.

It only took them a few more minutes to reach the next alleyway. "The victims were found only blocks from each other, positioned in nearly the exact same way. Again, both were of course drained of all their blood with no visible signs."

Like before, Yukio watched as Calista walked further into the alley, searching for something that likely wasn't going to be there. As she searched, he kept a look out, standing at the mouth of the alley, looking each way, making It seem like he too was looking clues of his own. What he was really doing, was trying to find who was watching, he could still feel their eyes on them.

He turned his attention back to Calista when he heard her giving an exasperated sigh. "There isn't any thing here either." She said, coming back to stand in front of him.

"Did you expect the results to be any different here than at the first location?"

"No, not really, but I was hoping that our demon would mess up at least a little. A drop of blood, something that could be of use." She crosses her arms. "He's smarter than I hoped."

Like a light turning out, the feeling of being watched disappeared. The tension he felt moments ago, suddenly left his body and he was able to relax. He watched as the same tension left Calista.

"He's gone." She said, lifting her head up to look towards the roof of the building surrounding them. "Alright," He watched as she lifted the sleeve of her jacket, to reveal a summoning tattoo on the underside of her wrist. "How about we take the fight to him now." Bringing her thumb to her mouth, she used her sharp fang to make a small cut along the pad. As blood welled up, she smeared it across the tattoo. "From the depths of the underworld, come forth Cerberus and do my bidding!"

Yukio watched her as summoned her demon hound. This was the first time he really saw her summon the hellhound that normally hung around her freely. He wasn't very skilled at summoning and controlling demons, but he could if he really needed to. Calista however, held a meister in being a Tamer, so where it took a lot for him, she made it look easy.

"Listen up, Cerberus, I need you to catch that demons scent and track him down. He was just here, so it shouldn't be too difficult for you to find his trail." When she gave him the command, she took on a demeanor he hadn't seen from her before. It wasn't her usual laid back self, but one of authority.

With a single nod, the hound leaps to the roof of the building. Before he could question her, Calista was climbing up the fire escape that would lead to the roof to their right. "Hey! What are you doing?!" He yelled out, grabbing the edge of her coat before she could get out of his reach.

When she looked down at him, the expression on her face said it was a no-brainer. "Hell hounds have an exceptional sense of smell, 20x better than that of a mortal hound. It won't take Cerberus long to pick up the scent of our killer and once he does, he'll lead me right to him. Then I'm going to defeat him."

"You can't go up against him on your own. I know I made it clear that Exorcists don't work alone." He released her coat. "You may not be a real student, but surely you know that number one rule."

He watched as she rolls her eyes. "Fine," she starts back up the ladder. "Come on then. I'm going with or without you, Teach." She didn't wait for him, climbing the rest of the way up and disappearing over the side, following her hound to the roof.

"Damnit," Yukio mumbles to himself. "She's just as stubborn as Rin." Still, he follows her up the fire escape and on to the roof.

Once he was on the roof, Yukio straightens his clothes and glasses. Looking around, he spots Calista on the other side, talking to her familiar, who had his nose to the ground.

"I thoug-" He didn't get the chance to say anything, as the hell hound lifted his head and took off, jumping over to another roof, heading east.

"He's got the scent. Try and keep up, Four-eyes!" Just as quickly, Calista follows, jumping easily to the opposite roof, keeping up with her demon.

His jaw clenched and so did his fists. If he didn't keep up with her, she would leave him in the dust. "Tch," Taking off in a run, Yukio just as easily leaps across, catching up to her and running alongside. He glanced over in time to see her give him a teasing smirk.

They ran on the roofs of the buildings, leaping easily from one to the other. Since they were both half demons, their endurance and strength far outweighed a normal human's and as long as the roofs weren't too far apart, they would manage easy enough. It didn't take him long to figure out that they were heading away from the busy city.

"Well, at least we won't need to worry about hurting anyone." He thought to himself as they came off the rooftops and back to solid ground.

"Yukio, watch out!" Calista's warning brought him back to his senses.

The threat was coming from above and if he didn't react quickly, Yukio would end up being hit by whatever was coming down on top of him. Pivoting his foot, he changes direction, jumping to the right, pulling both of his pistols from behind his back; just in time to hear a loud thud, followed directly by a cloud of dust.

Calista soon appeared at his left side, in her hands were a set of matching pistols like him; only hers were smaller to better fit her hands. "So she's a Dragoon as well as a Tamer…"

"Get your head in the game, Okumura, it would appear that he knew all along that we would follow him." Her eyes were completely focused as she aimed her guns towards the cloud of dust. "He led us here."

She was right. He needed to get his act together and focus on what was happening here and now. If he didn't keep his head straight, they were both likely to be hurt, or killed. Turning his attention on the cloud as it began to dissipate, his guns aimed at the center.

Someone began to laugh, the sound deep and distinctly male. "My, my, you are an intelligent young Exorcist. You figured it out all on your own and much faster than I thought you would too." He spoke with an accent, one Yukio didn't recognize.

Gripping the butt of his pistols more tightly, his fingers resting on the triggers, ready to fire, he addressed the male before them. "You are accused of killing two human women, and will be taken into custody. If you come quietly, we will not use force."

As the dust settles, a man appeared in the center of a small crater. He was tall, much taller than him, with black/blue hair that closely resembled Rin's. His eyes were a deep shade of crimson, that stood out against his unusually pale skin. Given the assumption that this demon was just like Calista, it was safe to say that he hasn't seen much daylight, preferring the night.

He didn't give Yukio an ounce of his attention, despite him talking directly to the man. Instead, his sole focus seemed to be on the female at his side. "You've grown into quite the beautiful young lady. I must say, you look like an almost exact copy of your mother."

From the corner of his eye, Yukio saw Calista suddenly stiffen. "I don't know who you think I am, but I can guarantee you don't know my mother and I know for a fact you don't know me."

"You certainly sound confident in that," He smirks, and when he did, he saw just a hint of fang; even shaper than Calista's. "Abandoned as a child, left all alone to fend for yourself." As he spoke to her, he began to walk forward.

"Don't move, damnit!" Yukio yells, his muscles tense as he steadied his aim. Again, Yukio seemed to be ignored completely.

"An unquenchable thirst for human blood," He continued to make his way to Calista, and Yukio could see that her hands were trembling. "Killing an entire village before being found and nearly killed by the very same Exorcist that took you in." He was within reach of her and extended his hand to touch her cheek. "I know everything about yo-"

Suddenly he was cut off as a loud "bang" echoed off the walls of surrounding buildings. A large hole could be seen in the center of the demon's hand where his palm had been, preventing him from actually making contact with Calista. Quickly, he jumps back, putting several yards between him and the Exorcists, his crimson gaze finally turning and acknowledging the boy.

"I told you not to move, damnit!" Yukio yelled out, smoke rose from the barrel at the end of his gun. "I won't let you touch her."

He could just make out the shocked expression on Calista's face, her eyes wide as she looked at him, her weapons lowering. "Y-Yukio…"

Across from them, the demon's eyes were narrowed in anger and hatred. "You damn brat," Yukio heard him say between clenched teeth. "You're in my way."

He didn't take his aim or eyes off the male, ready to fire a second time if he took another step towards them. "Move again, and the next shot will end your life."


So this chapter was completely in Yukio's Pov. Next chapter we'll be returning to Calista's to get her take on the situation. Who do you think the demon is and what might his connection be to Calista? He seems to know quite a bit about her, huh?

If there are any errors, I will correct them as I find them. I tend to write late at night, just before bed or during my free time while working and don't always catch mistakes until I've reread it after posting. Feel free to point any out.

Remember to send in those reviews!

Until next time~
