Hello everyone! Lately I have been addicted to this manga, so I just had to write a fan fiction about this! :D Sorry if it is kind of rushed. I really wanted to get the first chapter out before I go to bed (it's almost 3 A.M right now!). I am disappointed with the lack of OC fan fictions, I decided to put one out there! Please let me know what you think and I'll try to get the next chapter out soon! :D -miiika

[ C H A P T E R ONE ]; "darker than night"

Okumura Rin cursed to himself as he rushed out of the empty dorms. "Stupid Yuukio." Rin frowned, skillfully dodging the other students as he hurried to class. His sword was clutched tightly in one hand while his bag was in the other. "Can't believe he didn't even bother waking me up for class!"

As Rin approached the massive school, his frown deepened as he saw few students slowly making their way to class. It was one thing to be late to his Night classes, but showing up late to his Day classes was even worse.

He hated seeing the condescending smirk of Nagashiki-sensei as she marked him tardy for homeroom. Taking careful note of the time from the school clock, Rin panicked as he saw he had only five minutes to make it up two flights of stairs to his classroom.

"Argh! How bothersome! I'm going to totally kill Yuukio after this!" Making a dangerous turn to the left, Rin quickened his pace as he dodged the students like a mad man. The other students sent him dirty looks as he ran down the hallways, but it was to be expected.

True Cross Academy was a rich private school. People like Rin did not belong there, but after spending the last few months studying with the Night class, he learned to ignore the snooty private kids remarks.

As Rin finally reached the second floor of the academy, he took a quick left in attempts to dash into his class before Nagashiki-sensei arrived. His attempts was sadly cut short when he suddenly felt himself being pushed backwards by an unknown force.

Rin blinked in confusion as his things clattered beside him and a soft voice spoke in amusement. "You seem to be in quite the rush, Okumura -san."

Rin stared at the source of the voice, dumbfounded. The girl merely smiled as she picked herself up and gathered up his belongings. The girl was about as tall as Kamiki and her jet black hair was left down and reached her shoulders. She was fairly pale - as most of the girls in True Cross - and had sharp brown eyes. "Uh. .You are?" Rin finally blurted out.

The girl laughed as she held up a hand towards Rin. "Sorry. I should have introduced myself before." Rin accepted her hand and blinked in surprise as she easily helped him up. "I'm Yamaguchi Sakaya. I'm in the same class as you, Okumura-san."

Immediately, Rin blushed in embarrassment. He stared sheepishly at the ground as he rubbed the back of his head. He had been so busy keeping up with his Night classes that he hadn't bothered getting to know his classmates in the Day class. "I'm sorry! I. .er-" Rin paused as he tried to rack up a plausible excuse.

Sakaya merely dismissed his apologize with a quick flick of her wrist. "It's fine, Okumura -san." She said with a smile still on her lips. Giving his belongings back to him, she continued. "You always seem to have a troubled expression in class, so I won't pry too much."

Rin's eyes sparkled at the sudden act of kindness his classmate had just shown him. "W-Wow! You're super nice, Yamaguchi-san!" Maybe he should change his opinion about his fellow Day class students. .After all, she didn't treat him like he was trash.

Suddenly, Rin remembered the reason why he crashed into her. "Wait! Aren't we late for class?" He exclaimed, gesturing to the blatantly empty hallways. Sakaya blinked as she straightened her school bag.

"Eh? Don't you know, Okumura-kun? The headmaster cancelled classes today because it was some important 'national holiday'." Rin blanched as he vaguely recalled Mephisto telling the Night class that they were going to celebrate his birthday.

"Ah. But some of the students are here just to catch up on school work." Sakaya quickly added, explaining that she had to deliver some paperwork to the teacher's office because she was chosen as female representative for the class. "Well, if you excuse me, I'll have to deliver these papers and head to my part-time job." Sakaya began as she began to descend down the stairs towards the teacher's lounge.

Turning slightly to look across her shoulder, Sakaya smiled and waved Rin good-bye. "I'll see you in class, Okumura-san." Rin couldn't help but to return her smile and waved back, watching her figure retreat in the distance.

Once she was out of his sight, Rin lowered his hand and snapped out of his daze. His sapphire eyes shone with confusion as he remembered Sakaya's last words. "Weird. I thought students weren't allowed off campus without permission. ." Rin mumbled to himself, rubbing his chin as he decided to head back to the dorms until his Night classes.

"So then how does she have a part time job?"

When Rin arrived to his Night classes on time for once, he found the atmosphere to be heavy with dread. "Woah! What's going on in here?" He exclaimed, waving the air in attempts to get rid of the bad atmosphere.

Although Rin and his fellow classmates had been upgraded to the Esquire status recently, they haven't been allowed to oversee missions yet because Yuukio and the others teachers still believed they were too inexperienced.

Bon was the first to speak, "Shut up and sit down, you idiot!"

Rin's pointed ears twitched at the insult and waved a threatening fist in Bon's direction. "Why don't you come over here and say it to my face?"

"I rather stay over here than see your annoying, stupid smile!" Rin blinked, realizing that he did have a stupid smile stretched on his lips. Shima walked over towards Rin and patted his shoulder like a proud father.

"So, whose the lucky girl?" Shima asked, raising his eyebrows suggestively as he draped an arm around Rin's shoulder. Rin blinked cluelessly.

"What do you mean?"

"Oh you know~" Shima sang, nudging Rin with his elbow. "Something good must have happened for you to have such a smile!" Leaning in closer, Shima whispered into Rin's ear. "Oh, I know. It must have been, Shiemi-san, right?" Rin flushed at the mention of his current crush and snuck a quick glance at the said girl.

Shiemi noticed Rin's gaze and sent him a quick smile. The memories of the amusement park incident popped into his mind as he quickly adverted his gaze. This only fueled Shima's teasing. "Oh ho~ So it was Shiemi-san! You lucky dog!"

"So. .what did you guys do?"

"We didn't do anything!" Unfortunately, Rin added mentally in his mind. Even though he liked Shiemi, he knew that she only saw him as a friend and had eyes only for his brother. It was yet again another thing his brother bested him in. "I just met a girl from my class today." Rin explained, scratching his cheek with a sheepish smile of his lips.

Shima stared at his blankly as he removed his arm from Rin's shoulders. "So now you have two girls?"

"I don't have any girls! They are just friends!" Rin retorted, waving an angry fist towards Shima who raised his hands in surrender. "Ah, but are students allowed to get part-time jobs here?"

Kamiki entered the classroom just in time to hear Rin's question and snorted as she passed by him. "Students don't need to work at True Cross Academy since it's a school for rich students." She replied haughtily, taking her seat.

"That's true, though." Konekomaru spoke up as Rin glared at Kamiki. "Besides, Mephisto said during the student orientation that jobs weren't allowed because he wanted students to focus on their studies."

"But why the sudden question? Don't tell me you're trying to get a job." Rin dismissed the question with a casual wave of his hand.

"Me? With a job?" He snorted, "I have better things to do then try to make some money!"

"That's ironic coming from you Nii-san - who couldn't even keep a job for a day." Yuukio smiled, finally entering the classroom.

Rin flushed in embarrassment as his classmates stared at him. "S-Shut up!" Rin grumbled, shoving his hands in his pockets as he took his seat next to Shiemi with a pout.

"Anyways, as you guys know, the Day classes were canceled today due to a 'national holiday' set by Mephisto." Yuukio stated loudly, capturing the attention of his students. "This - of course - was a lie." The class stared at him dumbfounded. So why did he cancel classes then?

"We have received reports from town that people are mysteriously disappearing due to an unknown force. Classes were cancelled today because we have great suspicion that the next attack will occur at school."

"Therefore-" Yuukio was cut off short as his brother rose to his feet excitedly.

"That means we have a new mission, right?"

Yuukio sighed at his older brother's antics, but nevertheless smiled. "Yes, we have a new mission. It shouldn't be too difficult, seeing that the person behind these attacks haven't shown much aggression. At most, it's probably a low level demon stirring up some trouble."

"Ah, so it's like the boy in the amusement park?" Shiemi wondered out loud.

Bon raised his hand, "Wait. How are we supposed to find a puny demon and protect the students if the school is so big?"

"Ah. Well, according to Mephisto, we already have a general idea of who is going to be attacked next." Yuukio replied, "I believe her name is Yamaguchi Sayaka."
