Humming to herself, Aurora happily followed along behind the newly discovered half demon. It was a surprise that he was so energetic today he'd tossed and turned all night. She would know considering he had a bad habit of worming his way into her bed at night, completely asleep or fully awake, it didn't matter. Since she'd started living at the abbey he'd always make himself comfortable next to her than hog the bed to himself. Sensing a demonic aura approaching the icy eyed teenager turned just in time to see Mephisto appear in a wasp of purple smoke. "Sorry to keep you waiting~." Scowling Rin crossed his arms.

"So how do I become an exorcist at this school?" Laughing the green eyed demon tapped his cheek.

"My aren't you enthusiastic! Along with regular school you both will be attending cram school." Cutting him off the bluenette threw his hands up.

"Great I barely passed middle school with Rory's help, how am I gonna survive both of them?" Bumping her shoulder with his the white haired girl grinned remembering to keep her fangs hidden.

"Hey I'm still here for ya. Besides cram schools a lot easier than high school." Floating down from the lamp post he was perched on the purple haired demon cleared his throat.

"Yes well if you're done…" Aurora blushed ducking her head. "You'll start out as a page learning the art of exorcism. All though normal classes don't start until next week, cram school starts today." Pulling a key from his pocket Mephisto tossed it to Rin. "This key will allow you access to the exorcist school, be sure to keep it safe." Turning away the youkai snapped his fingers spinning back. "One warning. You must not let anyone know you are the son of Satan. Explain your ear and fangs however you like, but the blue flames are a dead giveaway." Growling the blue-eyed boy grit his teeth.

"I've got it." Waving him off the demon totted.

"Regardless I will be sitting in on your first day of class for my own peace of mind. Eins! Zwei! Drei!" In a sudden puff of smoke the 6'5'' demon changed into a little white terrier dog with a pink bandanna around his neck. Wagging his tail the tiny terrier trotted over to the female student. "If you don't mind, Mizuka-chan?" Blinking at the mutt she sniggered scooping Mephisto into her arms, ignoring the warning growl from her Hanyou friend. Rubbing her cheek on his furry head the girl laughed.

"I think I like you better as a dog." Shaking his head wildly the bluenette gaped.

"Can all exorcists change shape?!" Wiggling further into her chest the terrier woofed.

"No, just me." Pointing towards the nearest door with a paw he wagged his tail. "Try your key there." Scratching the back of his head Rin did just that blinking in surprise when he opened the door and it looked like a whole different building. Nudging the boy along Aurora opened the door to room 1106 peeking inside.

"Wow only seven more people? I don't guess cram school is very popular than." Taking a seat beside Rin she gawked when he pulled the white dog out of her lap and set him on the table. Giving him a glare for good measures the half demon crossed his arms sliding back in his chair, simply stating.

"He doesn't need to be that close to you." Patting his hand with was gripping Kurikara she giggled. He was nervous so he was moodier than normal, which in Rin's case always spelled trouble.

"Oh Hot-Head…" Eyeing the two teenagers Mephisto smirked, oh so that's how it was… Wonderful!

"All right settle down!" Head snapping to the right the bluenette gawked watching his younger brother shut the door behind him making his way towards the teacher's desk. "Take you seats everyone. The lesson is about to start." Looking between Yukio and the door Rin grabbed his hair.

"What the hell!?" Ignoring his brothers shouting the brunette continued on.

"It's a pleasure to meet you all. I will be your teacher in anti-demon pharmacology, Okumura Yukio." Standing up the bluenette knocked the desk behind him over.

"Yukio?!" Grabbing his hand before he could do anything else the teal haired girl pulled him back down running her thumb over his knuckles.

"Wait until after class to start something." Growling he gave one last glance at his twin before calming and muttering under his breath. Giving a grateful smile to the silvery eyed female Yukio continued.

"As you can see I'm the same age as most of you; this will be my first year lecturing and since my assistant brought it upon herself to arrive with the class I assume she is also prepared for today." Sighing Aurora pushed herself up dragging her feet to the front of the class room to stand beside Yukio. Blushing she tried her best to look up without any success.

"Hello I'm Mizuka Aurora. For this class I am the assistant teacher, but also one of your fellow students as well." Pushing his glasses back up the brunette nudged her aside realizing she was close to hyperventilating.

"Even though we are the same age Mizuka-Sempai and I have already studied the art of exorcism for two years. As such I would like you to address us as sensei." Rin who had been shaking since Aurora had left his side clinched his fists. "Now first things first, how many haven't had a temptaint before?" Watching 3 students raise their hands Yukio smiled. "That's not a problem." Pulling a vial of animal blood from his bag he went on to describe how goblins inhabited the room.

"Mephisto?" Blinking the dog looked over at Rin cocking his head. "What's a temptaint?" Trotting closer the terrier sit down.

"A temptaint or masho is an injury or illness brought about by a demon. Once a human obtains one they can see demons for the rest of their life. Your brother is the youngest person to get a temptaint. A genius anti-demon pharmacologist, Mizuka-chan isn't all that good with pharmacology but offered to help Yukio in any way she could. It was surprising considering she refused her scholarship last year to stay at the abbey with you two." Slamming his hands down on the table Rin stood up.

"Oi!" Marching up to the desk he growled glaring at both of the teachers. "You have some explaining to do." Looking up from mixing the animal blood briefly the younger twin sighed.

"I'm teaching a lesson right now. Can't this wait until later?" Grounding his teeth the bluenette paused when a cool hand touched his arm. Shaking that hand off he continued.

"We need to talk! Now!" Smacking the hand that was holding the rotten animal blood both boys watched as it tumbled to the ground and shattered. Covering her nose as a demonic presence became known, Aurora coughed.

"If everyone will please wait outside, I'm afraid Okumura-sempai and I need to deal with this before it gets out of hand." The class complained but made their way out into the hall. Really this was for their safety, not hers. Pushing his glasses back up Yukio pinched the bridge of his nose.

"It's just like I said. Aurora and I became exorcist two years ago. We started training when we were 7 and 8. I got my Masho from you on the day I was born. I've been able to see demon since I can remember. I've known all along." Swallowing the half demon turned towards the silent female.

"And you? How long have you known?" Pushing her hair aside she traced the light scar where her neck met her shoulder.

"Remember in kindergarten when you bit me? That was my temptaint." Remembering back to that day his eyes went misty for a second.

Humming happily the 5 year old bluenette stacked another block hoping to impress his younger brother. Looking over to what Yukio was doing Rin gaped realizing the brunette had already passed him in block stacking. It didn't matter anyway, every time the tower got more than 5 blocks it tipped over. Hearing a soft giggle behind him he blue eyed boy spun around locking eyes with the cutest girl he'd ever seen. Glossy black hair framed her face and silvery ice blue eyes twinkled. Playing with the hem of her Dinosaur shirt she looked down blushing. "You're building it wrong." Blinking he gave an oh so intelligent response of 'huh'. Shaking her head the little girl got on her knees beside him beginning a three wide block tower. "You never stack only one, it'll always fall. Three is a good number though." Watching her stack 2 then 3 then 2 he smiled. No one ever played with him, having someone new to play with was kind of awesome. Feeling cool hands guild his to the tower he shook himself out of his stupor. "Here you try. I'm not gonna build it for ya. You have to beat your friend on your own." Continuing her pattern the little boy had to admit her idea worked a lot better than his did. Remembering what she said he paused.

"He's not my friend, he's my brother." Looking up from her own stuffed bat plushie she bit her lip.

"Are you sure? But your hair's blue and his is brown…" Shrugging she went back to playing with her toy. "If you say so then." Realizing he hadn't seen her play with any of the other kids before Rin frowned crawling over to her side.

"How come you're playing with me?" Aurora set her little black bat in her lap petting it.

"I don't really know. You seemed like you were having a hard time so I thought I'd help. I'm not used to other kids; I always play alone at home." Blinking she realized she hadn't given her name yet. "I'm Aurora." Smiling Rin puffed his chest out.

"Name's Rin." She laughed at his tiny show of manliness.

Hearing a commotion in the hall way the little raven looked up from her doodle with red puffy eyes just as a teacher ran by carrying a kid from class B. "That little hellion's gone crazy this time! Hurry someone call an ambulance!" Setting her crayon down Aurora swung her feet wondering what had happened. Remembering Rin was in class B also she jumped up running out the room before the teacher could stop her. Sliding to a stop behind the two teachers from class B she bent down peeking around their legs. Taking in Rin's wild looking eyes and his heaving chest she gasped as he threw a book at the brunette sensei. "Get away, don't come near me!" Screaming she darted back out of the classroom letting Father Fujimoto take over.

"Rin that's enough!" Knocking a chair away he frowned harder. "Do you have any idea what you did to that boy? He's in the hospital now, suffering." Baring baby fangs the bluenette growled.

"So what? He took Rory's bat away from her during recess and pushed her down. He deserved it!" Looking for something else to throw he hurled the desk beside him. Shiro winced when the metal frame hit him. How was her friend throwing those things? They weighed more than she did. Looking up at the adults in front of her, Aurora frowned. They were supposed to help. Not gossip. It wasn't Rin's fault, he was only defending her. When she'd fallen she'd gotten a cut on her knee. He was protecting her.

"Look at him, he looks like a demon!" Turning to the two Shiro smiled.

"Ladies please, its dangerous, stay back." Nodding both stepped away from the door. Seeing her chance the tiny raven dashed between them.

"Rin!" Eyes widening the priest made a grab for the girl only succeeding in making the boy snarl and pull her to his chest holding her in place. The little blue eyed boy couldn't describe it but a sense came over him that made him think everyone was trying to take the tiny girl in his arms away, so following what his instincts were telling him to do he sank his fangs deep into where her shoulder met her neck giving a happy bestial sound when she clung to him tighter. Pulling back he blinked finally realizing what he had done. Giving him a shaky smile the girl patted his cheek. "Are you okay now?" Feeling her sag against him the bluenette panicked. Looking around frantically he locked eyes with his father.

"Dad! Help!" Pushing his disbelief at what he had just saw away for a moment Shiro swept the girl into his arms noticing that Rin never let go of her hand throughout the whole wait for the ambulance or the ride to the hospital, not until he fell asleep that night and even then the exorcist had to pry his hand away.

"Rin!" Blinking back to the present the half demon jumped having not noticed how close Aurora had gotten. "Please move your blue flaming ass to one side of the room." Stepping away, only then did he realize demons were floating in front of them hissing softly. Pulling her knife from the sheath strapped to her leg the white haired girl clicked her tongue counting off how many there were. "Two dozen. Alright Yu you take the 8 over there and I'll take the 16 over here." Clicking the safety off his guns Yukio snorted.

"You're blind, clearly there are more on my side of the room." Realizing they planned on ignoring him, Rin felt his eye twitch.

"Now wait a damn minute, we're not done talking yet!" Letting her knife drop from her hand Aurora grabbed the chain swinging it in an arch, taking out 3 hobgoblins in one move, while the brunette downed another 4. Turning away from the demons Yukio pushed his glasses back up before firing over his shoulder, he couldn't let the girl have all the fun.

"I have nothing more to say to you." Jumping over a desk Aurora tripped sliding under a medium sized demon. Catching her breath she righted herself swinging the chain in another arch catching 2 with her knife. Seeing his partner needed back up Yukio reloaded his guns clearing the next wave. "We are rather busy Nii-san." Taking a chance to see how Rin was fairing the female laughed barely dodging a large hobgoblin's paw when it swiped at her. A smaller youkai was gnawing on Rin's head, leaving pieces sticking up with goop.

"Y-you're being eaten!" Giggling she rolled away from the oncoming wave of goblins. Seeing a small demon duck behind a desk feeling Rin's energy spike she followed suit peeking over it just in time for a wave of blue fire to burn the other demons in the room. Throwing the end of her chain that had the weight on it she grinned as it wrapped around the tiny goblin making sure it couldn't get away.

"Listen to me dammit!" Turning back to the bluenette she frowned. Moving around she placed a hand on his still fire engulfed shoulder, wondering why they didn't burn like everyone said they did. All most instantly the flames died down leaving the boy growling. "If you both knew everything all along, what did you think of me?" Yukio gave a humorless chuckle reloading his guns and pointing them at his brother, who gawked.

"What did I think about you? It should be obvious. You are a demon and a threat to us all." Baring her fangs, Aurora pushed past Rin standing between the twins. Tilting his head the younger brother smiled pulling back the hammer on his gun. "Do you think I have a problem shooting you too? Tell me Nii-san why did you want to become an exorcist? Revenge? Atonement? If that's it you should've given yourself up to the order or better yet died." A deep rumble started behind Aurora making both exorcist freeze. Pulling his sword from his shoulder the half demon snarled letting the red sleeve pool at his feet of the floor.

"I don't care if you point that thing at me, and whatever you say I probably deserve it, but don't ever aim at Aurora." Unsheathing his sword the page darted past Yukio sending a wave of blue flame towards the three attacking demons that were sneaking up on the distracted dragoon. Locking blazing red pupils on his closest friend the Hanyou growled letting his tail lash around. "And what do you think of me, huh? Am I a monster to you?" The 2nd class exorcist smiled wrapping her arms around Rin's waist.

"Human, Demon, it doesn't matter to me. You're Rin either way, and I'll always be there for you." Letting his flames die down to a dull roar the bluenette sniffed hiding his teary eyes in her shoulder. Watching the blue-black furred tail behind him give a lazy wag she giggled. "Besides you're adorable like this. You have elf ears and a tail. How could I be scared?" Grinning he pulled away wiping his eyes before bopping her on the head with his sword's handle.

"Oi I'm not cute either." Blinking at the sudden change of mood Yukio put his guns away watching the two pick at each other. "Hey Yukio, I want to become strong that's why I want to be an exorcist. So no one has to die for me again." Aurora gave a tug on Rin's ear and he pulled her hair, she pulled his tail making him stop and melt like jelly to the floor. Staring up at her with hazy eyes he grinned not quite understanding what just happened. Crouching beside him she scratched her cheek thankful she had demanded that Mephisto let her wear the boy uniform instead of the girls.

"Well that's never happened before. Normally if you pull a demon's tail they attack." Pulling the still dazed half demon up she helped him over to his seat or what was left of it. Leaving him leaning on the table the teen went over to where she had left the small goblin tangled in her knife's chain. Shushing it she scooped it up gently unwrapping it. Muttering more to herself than anyone else she continued where she'd left off. "Demon's only let their mates anywhere near their tails…" A sudden knock at the door had all three jumping. Hurriedly snatching the Kurikara's sheath up the white haired female stuck the sword back in sighing when the blazing blue flames disappeared.

"Sensei are you alright?" Sweat dropping, the younger twin groaned looking around at the room.

"Yes! We're fine!" Giving the blue flames a lingering glance Aurora snorted watching Rin try to put them out with calming motions with his hands. "The room is a different story though." Getting a nod from Yukio she opened her hand facing it towards the ceiling or more the sprinklers. Giving a burst of Youki water started raining down putting out the fires before they spread too much. Opening the door the 1st class exorcist smiled. "I'm sorry everyone but it looks like this room isn't usable anymore. Let's continue in a different classroom." Ushering the others away from the scene the taller twin sighed. "You too Okumura-kun. It's a shame one demon couldn't be spared." Making sure Rin was alert again Aurora held out the little hobgoblin for Yukio to see. It squeaked indignantly up at her.

"Nope I saved one. All that violence wasn't pointless after all."

"602… Room 602." Stopping outside the door Rin frowned seeing Aurora continue on past him. "Oi Rory which room are you in?" Fishing around in her pocket she tugged the paper loose.

"Umm… 603. I'm just across the hall." Nudging the door open she tossed her bags in before coming to stand by his side. Squeezing his hand she smiled as he opened the door….

"What the hell, Yukio!" Spinning to grin at them from his chair the brunette laughed.

"Surprised! Normally freshmen room together with 4 people per room but they made a special exception for us since you're dangerous. You need someone to keep an eye on you, I volunteered." Slinging his bag on the empty bed Rin huffed.

"What is this, a jail?" Patting him on the back the female flopped down on his bed coughing as a cloud of dust rose.

"Yep and we're your jailers." Grinning the half demon fell across her earning a soft 'umh' when he landed.

"Bring it on! This'll be a piece of cake." Pushing his glasses into place the younger twin cocked an eyebrow.

"You think so, huh? Well in that case get started on the homework I assigned." Raising up the bluenette blinked letting his tail uncurl from his torso.

"What homework?" Petting the ball of fluff that landed on her chest the teal haired girl laughed.

"Come on Hot-Head grab your book and I'll show you." Rolling off of her the boy unzipped his bag grabbing the anti-demon pharmacology book before rolling back over. A sudden thought hit him.

"Oh man that means I can't lie that the dog ate my paper if you live with me!"

Read and review and tell me if I step into Mary-sue land.
