A small boy ran into his bedroom and slammed the door behind him. His chest heaved as he slid against the door onto the floor and broke into heavy sobs. His hand groped for the lock on the doorknob, turning it after he found it. His head sank into his hands as the tears rolled down his cheeks. A loud sob reverberated through the silence as he started to cry harder. His memories flashed back to a few minutes ago before school had let out. He was packing up his books in his bag while the teacher was talking about handing out the test from the previous day. The teacher walked around to the students and gave them a small comment on his thoughts about their test performance. He came around to everyone except the last row when the bell rang. The students started to run for the door of the classroom, fighting and all of the things that you would expect out of a group of ten year olds. The teacher came to him and the teacher's bright smile turned into a frown. He handed the boy the paper and shook his head slightly.

"I'm surprised. I don't know what happened to you! Go home and show this paper to your father and have him sign it, since you didn't get above the approved grade."

The boy looked at his paper and a gasp of surprise left his mouth as he looked at the 43% that he had scored. His visions started to get blurry as he stood up and threw his bag on his shoulder. He ran out of the room with the failing grade crumpled in his hand as he stopped quickly by his locker to grab his homework. As soon as the homework was in his bag, he ran through the crowded halls of the school and out into the street, turning to the right and tracing the familiar path to his family home.

Now the boy was on the floor with his back to the door sobbing his eyes out. In his hand was a piece of paper, the source of his emotional discontent. He clenched his fist harder together and gritted his teeth. A wave of anger overtook his as he threw his paper on the floor and let out a scream of rage. He glared at the paper as salty tears ran down from his cheeks and into the corners of his mouth. Suddenly, a knocking was heard from the other side of the door. The boy growled in frustration as he told the person on the other side of the door to go away, knowing full well who it was. A sigh was heard from outside of the door above the small boy's heavy breathing. Footsteps receded from the doorway as the man walked away. The boy groaned, rubbing his throbbing temples, trying to displace the headache that was sneaking up on him from all of his pent up stress, anger, and sadness. He glared at the paper ball on the floor and wished that it would disappear so he wouldn't have to deal with his father, whom he knew was going to be livid.

Suddenly, the paper started to smoke. Stunned, the boy let a gasp escape from his lips and tried to walk backwards away from the now heavily smoking paper. His breathing had escalated quickly as he fell onto his bed. The boy glared at the paper with hatred etched across his face. Unanticipatedly, the paper burst into flames. Not just any normal flames, but bright blue flames. The boy panicked and let out a scream as the blue flames devoured his paper. The boy barely noticed the door to his room being unlocked and a man stepping in with a fire extinguisher, cutting down the flames before they got out of control. The boy's eyes were transfixed on the ashes of what had been a paper on the ground. His vision was blocked as he was embraced my the man that had killed the flame. The boy took a shaky breath and sobbed into the man's shoulder, savoring the familiar smell of gunpowder and cigarettes that always made him feel protected and safe. The man stroked his head as he whispered soothing words to the small boy.

"Mr. Okumura!"a voice called out.

Yukio looked up from his papers, or rather, his thoughts, and saw the hand that was raised in the air.

"Yes, Shima?" he answered.

"Do we have to write out the terms or can we bullet them?"

"Uh, bullets will be fine." Yukio answered.

He sighed and looked down at the assignments that he was grading from the previous class. He grabbed his pen that had been lying on the desk and looked to his answer key. He sighed as he marked yet another question wrong from the same paper. The tallied up the points and put a final grade on the top of the paper with a note requesting the student to do another one and turn it in. He looked at the grade that he had scribbled down on the top and realized that he had miscalculated his math. He drew a line through the incorrect grade and wrote down a 43%. His memories flashed back for a moment to that terrible day before he forced himself to focus on his work. He glanced at his watch to see how much time was left before the bell rang. Three minutes. Yukio flipped the failing paper over on started to grade the next one. He rubbed his temples and slipped off his glasses. He let his body go on autopilot and his mind slip away to a couple weeks ago. Blue flames danced around his memories as he thought of his brother sitting in the front row, tail twitching as he searched his brain for an answer. He thought of last weeks doctor's appointment and what they told him. He thought about Rin and his upcoming exorcist exams in two weeks, panicking as he thought about Rin's ability to control his flames. Rin still hadn't gotten them completely under control, but they were good enough for now. Yukio started to calculate the chances that his brother had of passing his exams from the experience that he had had himself. The bell rang, signaling the end of cram school. Yukio stood up and slipped his glassed back on, then addressed his final class of the day.

"Ok, if you haven't finished your test yet, please stay after and finish it. If you are finished, I'll be standing by the door to collect them. I will most likely have them graded by tomorrow. Have a good evening."

Yukio walked over to the door as the students stood up and handed him the tests. He bid each of them a good evening and collected their tests. He closed the door after the last student had left and sighed, running his hands through his hair and pushing up his glasses. He walked back over and plopped down into his chair.

"You ok?" Yukio heard his brother ask.

"Yeah, I'm fine," Yukio lied, "Are you finished with your test yet?"

"Almost," answered Rin, "I just have to finish with the essay then I have training with Shura. I'll be back to the dorm in time to whip something up."

Rin wrote down a few more words then stood up and packed his things. "Don't worry, Yukio. If you have any problems, or just want to talk, your big brother is here."

Yukio faked a laugh and replied, "You were only born a few hours before me at most, you're not that much my superior."

He rolled his eyes as he swung his sword over his shoulder. He walked over and handed me his test paper. He walked to the door and took out a key, putting it in the lock and turning it. He opened the door and walked through, closing it behind him.

Yukio let out a long drawn out sigh as relief flooded over him. He was finally alone. Alone and at the mercy of his thoughts and emotions. To him, the brain was the scariest place for him to be. He opened a drawer of his desk and took out a mirror, looking at his reflection. Somber teal eyes stared back at him through the corrective lenses that earned him the nickname four-eyes. Two moles under his left eye and one on the right side of his mouth like always. But some of his features had changed and ultimately, his life had changed. His brother was supposed to be the one with the demonic powers, the features, the unchecked actions. He was supposed to be the level-headed, completely human, serious brother of the demon. He was too weak to handle the powers, that was what his old man had told him. He was always weak. That's why he became an exorcist, to become stronger. Or was it? Did he actually believe that, or was it something else? Did he want to show up his father and his brother, who seemed to get all of the fame and glory? Maybe he wanted to have power for some other unknown reason. He didn't know. Perhaps he wanted to come out on top? Yukio clenched the mirror in his hand as he thought back to the day when he had failed that test. The day his powers first had shown. His powers. He wasn't supposed to have them. Why did he? Yukio knew why, but he just didn't want to admit it to himself. The mark that he had kept hidden for so long was the answer. His temptaint from Rin when he was a child had been on his shoulder. He had known that this would happened eventually, but when his blood tested positive for it, he was scared out of his mind. Now here he was, Yukio Okumura, a half-demon, like his big brother Rin.

His reflection stared back at him with pointed ears and sharpened canines. Yukio knew that he had always possessed some demonic power, ever since the day that the paper had burst into blue flames. He figures that since he couldn't possess the full potential of a demon, he would have some fallbacks. He did before he became one. His temper was one of them. That was why he tried to repress his feelings from everyone. He thought back to when he had transformed into a demon. All because he was born into a screwed up family that made some really bad choices on their part was why he was here. He thought back to last week when he and Rin had gone to visit their mother's grave. When he asked Rin if he thought it was a mistake that they were born, Rin replied with his bright and perky self. Always optimistic. However, even though Rin thought that they were worth something, Yukio always thought that it was a mistake that they were born, especially himself. He thought that the world shouldn't deserve something as weak and now, demonic as him. He looked back to his reflection in the mirror and saw that he was cry, the tears silently rolling down his cheeks. He gulped in a breath of air and put the mirror away in his drawer before he get lost deeper in his mind, a terrifying maze of instabilities. Before he closed his desk, he looked at the silver tin that was hidden away in the corner of the drawer. Yukio carried it around with him everywhere, even into battle. Not exactly the best decision on his part, but he never knew when he would need it. Yukio calculated whether he should take the tin home with him and open it there or whether he should do it at the cram school. Yukio decided it was in his best interests to take it home with him, so he stacked the papers that he had been grading into a pile, placing the answer sheet on the top. He grabbed his briefcase off the floor and popped it open, placing the papers inside of it, shifting his extra prepared magazines to the side. He grabbed the tin and held it up to his eyes, looking at the light reflected off of it. He tore away his gaze and placed the tin in his briefcase, closing and latching it afterwards. He was about ready to leave when he saw a hobgoblin in the corner of the room. Without hesitation, Yukio reached for the pistol on his side, without even bothering to take aim, he cocked and fired the gun. The holy silver bullet hit the demon dead center. The hobgoblin dissolved into thin air as Yukio holstered his gun, flicking on the safety with his thumb. Yukio walked over to the door and was about to put in his key when the door opened from the outside.

Yukio went wide-eyed in surprise and stumbled backwards, catching himself on one of the tables. The man in the door way sung his umbrella over his shoulder before looking at Yukio.

"Oh dear. I am so sorry my boy. I thought that you would be staying a little bit later grading papers and making lesson plans."

Yukio sighed in displeasure as he looked at the man in front of him. "I'm sorry, Sir Pheles. I was going to head home a little bit early and grade papers there."

"Oh, that's perfectly fine Mr. Okumura. However, I shall need to speak to you about, certain issues, let's say." Mephisto said with a grin on his face.

Yukio, completely unaware of what he was talking about, nodded as Mephisto closed the door to Yukio's classroom and pulled out a set of keys. He flipped through the many keys until he came to a pink one, which he promptly inserted into the door and opened it. He gestured for Yukio to go in front of him. Yukio obliged and went through the doorway and into a hallway that he had never seen before. Mephisto stepped through and closed the doorway.

"This is my home," said Mephisto as he lead Yukio through yet another doorway, "We need to talk about something very important, Mr. Okumura."

He gestured to a chair that he had pulled up to a coffee table. Yukio sat down. He knew that he had to appear relaxed and comfortable, or Mephisto would sense that Yukio didn't trust him. Yukio kept his mental guard up, but continued the conversation.

"What does Rin need to do this time?" Yukio asked, curious as to what Mephisto would want him to do with Rin this close to his exorcist exams.

"Oh no, Mr. Okumura, you misunderstand. I wasn't talking about your brother. I was talking about you."

Hey guys! So this is my first fanfic in the Blue Exorcist, or really even anime category. You may have noticed, but my account is mainly Star Wars. I wanted to try something different, especially with a character that I really love. No seriously do not look at my wall near my desk you will see Yukio Yukio and double Yukio. So yeah. This book will have some cussing in it later on but the show and the manga hav that in it so suck it up. Oh, and there are 3000 words in this and I am really proud of myself cause that's a lot. Also, I am basing Yukio's character off of the anime, but I will throw in some manga here and there. I feel like more people have seen the anime than read the manga. As for me, I am in the process of reading the manga myself. Anyways, thank you for reading and supporting me. Thanks for the votes too. Also, if you have any ideas, please feel free to comment or PM me. I'm also always avaliable if you just wanna talk Blue Exorcist or something. Thanks again. *gasp* SATAN!
