Disclaimer: I do not own Blue Exorcist!

Sorry for not updating in forever! So much stuff happened to me! I got suspended from school for punching a girl in the face – though I only did it because she was bullying my little sister. What kind of loser, sixteen year old bullies a thirteen year old girl? It's pathetic. Then exams, family issues, and I'm also lazy! So it is a mixture of everything really for not updating!

"Talking"

'Thoughts'

Emphasis

~X~

Rin jumped to her feet, pointing a shaking finger at her brother.

"Y-Yukio?!"

Yukio looked directly at Rin and gave her a small smile, but that was as much acknowledgement as he gave her.

"It is nice to meet you all." He continued on. "I am a new teacher here. I will be teaching you all Anti-Demon Pharmacology starting today."

"Nice to meet you." The purple-haired girl said politely, while also somehow managing to sound snobby.

"Pleased to meet you…" Her friend spoke shyly, hiding behind her book.

"Hello!" That was the pink-haired boy from behind Rin.

Rin was beginning to get annoyed. "What the hell! Yukio!"

"What's wrong?" Yukio looked at Rin. His expression and voice were calm.

"Don't you "what's wrong" me!" Rin shouted angrily. She wanted to know what the hell was going on here. "What's wrong with you?!"

Yukio once again smiled, which Rin didn't like because she knew his smile was fake. He spoke, "Although, I'm the same age as all of you, I've been studying Exorcism from the age of seven. I finished my studies two years ago. So please address me accordingly while in class."

Rin slowly lowered her hand, hardly believing what she was hearing. "From the age of seven…? You've got to be kidding…" She whispered.

"He's a genius in the field of Anti-Demon Pharmacology, and the youngest person ever to get an Exorcist certificate." Mephisto explained to Rin.

Rin looked down at him, then back to Yukio. Slowly, she sat back down, feeling as though she'd just been slapped in the face.

"Is there anyone who has yet to receive a Temptaint?" Yukio questioned, looking around the room at his students.

Rin didn't look to see who raised their hands. She just continued to stare at Yukio, mentally willing him to make eye contact with her.

"Three… Then let's start the first class with the Temptaint Ritual." Yukio continued on, still ignoring Rin.

"Temptaint Ritual…?" Rin muttered, looking at Mephisto.

"He will summon a demon, and those who have yet to be afflicted will receive their Temptaint." Mephisto quietly explained.

Yukio was speaking again, "Actually, this classroom is usually vacant, so it has become a nest of goblins."

"Huh? A-are we s-safe in here?" The shy, brown-haired girl from before said.

"Don't worry." Yukio assured her. He grabbed his briefcase, opening it up. "They are low-class demons without any power in particular."

'What is going on here, Yukio?' Rin thought, clenching her fists. 'You…'

Rin got to her feet again. She had questions to ask. "Hey, Yukio!"

"You are in class. Sit down." Yukio instructed without even looking up as he rummaged through his briefcase. "As I said earlier, goblins are low-class demons…"

Rin tuned him out. She didn't care about what he was saying. 'Could it be… that he knew… about Father… and about me?'

"… even so, they are still demons." Yukio was saying. He was holding up a vial of red-liquid.

Rin slammed her hands on her desk. "Hey, Yukio!" She shouted at him. "Explain it!"

Yukio simply ignored her, closing his briefcase. "If they smell rotten animal blood, they get excited and go wild."

Rin was now pissed… and it was never a good thing when she was. She moved away from her desk, making her way over to the teacher's desk, ignoring the stares she was receiving from her fellow classmates.

"Wait a sec, Yukio!" Rin practically growled, grabbing onto Yukio's arm and pulling him. "Explain this to me! Yukio!"

Yukio was now glaring at her, something which was rarely seen. "What do you mean?"

"Are you screwing with me?!" Rin snapped. She could see all her classmates look at her with annoyance and irritation.

"I guess this can't be avoided." Yukio almost sighed. He looked up at the seven students. "I'm sorry, but please wait outside the classroom while I have a little chat with Ms. Okumura."

Rin glared at Yukio when he addressed her as "Ms. Okumura".

"Jeez! Annoying brat!" The boy with the large, blonde streak running through his short, messy brown hair said. His tone of voice was full of annoyance. He got to his feet with his friends and left the room with everyone else.

Rin gripped Yukio's arm even tighter, trying to control her anger.

"So? What did you want to ask about?"

"Don't play dumb with me!" Rin yelled. "What's going on here?! You never told me about this!" She looked at dog-Mephisto when she shouted the last part.

"I guess you should just explain." Mephisto spoke to Yukio.

"As I said earlier, I became an Exorcist two years ago. I was training from the age of seven under the guidance of Father, of course." Yukio said without even looking at Rin.

"The Old Man?" Rin said softly, though there was still anger in her voice. "Then you knew everything about his work?"

"Yeah." Yukio replied simply and casually. "You were the only one who didn't know." His tone was changing, almost sounding bitter. "Since I received a Temptaint from my demon sister when we were born… I've been able to see demons for as long as I can remember."

"That's… but why?" Rin grabbed Yukio's shoulders, making him look at her. "Why didn't you tell me anything until today? I asked you why?!"

"Let me go." Yukio began, pulling Rin's hands away from him.

"Yukio!" Rin grabbed the collar of his coat and threw her weight at him, pushing him back. His hand swiped at the edge, looking for something to grab onto, but he knocked the vial of rotten animal blood off the desk. It fell to the ground, shattering into tiny pieces, the blood splattering around.

Yukio and Rin stopped, turning to look at it.

"T-that stink!" Rin covered her sensitive nose.

Suddenly, the pipes on the ceiling all started to burst, filling the room with what looked like gas. Rin stood there frozen, looking around the room. She looked to the side – just in time – to see multiple goblins coming at her.

They all had small, round bodies with short, stubby hind legs and thick forelegs/arms. They were mostly green, red, and purple in colour.

Yukio grabbed her arm, pulling her back.

The sounds of shots then filled the room, startling Rin, and killing the goblins that had attacked her. Rin looked to the side to see her brother holding a handgun.

"Y-Yukio…?"

"Hobogoblins," Yukio said, lowering his gun. "There are many of them, so they go even wilder." He pushed his glasses up. "I'll get rid of them, so you…"

"We're not done talking yet!" Rin shouted, cutting Yukio off.

There was a sound of attack and more hobogoblins were appearing in the room, coming straight at Yukio and Rin. Yukio was shooting with great accuracy, and he even pulled out another one, quickly reloading the guns whenever was needed.

"Yukio… w-what did you think of me… all this time?"

"What did I think about you?" Yukio said, turning his back on Rin. "That should be obvious." He suddenly held his gun over his shoulder, shooting without even looking. Rin watched in amazement as the bullets zoomed past her, hitting the hobogoblins perfectly.

Yukio whirled around, glaring at her. "You are a demon… and as such, you pose a great danger."

Rin's eyes widened.

Yukio continued shooting the hobogoblins and reloading. Not once did his calm and even disposition disappear. "You're such an idiot, Rin-chan." He told his sister. "Why did you want to become an Exorcist? Revenge? Or… is this how you want to repent for what you did to Father?"

Rin bit her lip, feeling her tears gather in the corner of her eyes when she heard the part about Father.

Behind Yukio, three large hobogoblins had appeared out of what looked like rifts. "If that's how you really think…" He turned around, shooting the hobogoblins with ease. "You should quietly hand yourself over to the Order, or just die."

"Are… you saying it's my fault that he died?"

"Isn't it so? He was protecting you all this time. And I was watching the whole time." Yukio turned around. He lost his composure and was now shouting. "Since Father was the only one who could resist being possessed by Satan, he was constantly being targeted by Satan! He kept Satan at bay with pure willpower! He was the strongest Exorcist!" He shot a hobogoblin that had appeared at his side without looking. "As long as his willpower didn't falter…" Yukio was shooting more hobogoblins. "There's no way Satan could have possessed him! You said something to him, didn't you?!"

"Do not ever call yourself my father again!"

Rin blinked, remembering the words she'd spoken.

Yukio reloaded his guns, speaking once more, "If Father had any weakness… it would have been you, Rin-chan." He pointed his now-fully loaded gun directly at her. "You killed Father!"

"Listen, Yukio…" Rin gritted her teeth, blinking back her tears. "You're right to call me an idiot, so I don't care what you tell me. However…" She clenched her fists and began trembling, her blue flames spreading out around her body. "Don't you go pointing a gun at your sister! We're siblings, aren't we?!" Her blue flame reacted wildly with her anger.

Yukio stepped back, covering his face. Some of the lights around the room shattered and more hobogoblins began appearing through rifts.

Rin moved quickly, heading over to her desk and grabbing her sword. She then whirled around in time to face Yukio and his gun.

"I didn't kill our Father!" Rin shouted, removing the red cover for her sword. "If shooting me would make you feel better…" she lifted the Kurikara up, drawing it open. "… go on and shoot!"

Her pointy ears lengthened, her teeth and nails grew sharper, and her tail uncurled from around her body, coming loose.

"Shoot!" Rin shouted at him, charging forward with her sword in hand.

However, Rin ran right past Yukio, surprising him. He turned around to see the largest hobogoblin behind him. Yukio watched as Rin jumped up, slicing at the hobogoblin with her sword, cutting it right in half.

Rin sheathed her sword, her human features once again softening out her demon ones.

"Don't think so lowly of me. I won't fight my brother." Rin scoffed.

Yukio stared at Rin in disbelief and surprise. He then turned his head away, looking guilty, ashamed, and sad. "What were Father's last moments like?"

He had spoken so quietly that Rin wouldn't have heard it if she didn't have demon hearing.

Rin looked down, smiling lightly, remembering Father. "He was cool. He died protecting me to the very end." She spoke. "I didn't decide to become an Exorcist out of revenge or some complicated reason like that. I just want to become stronger! I don't want anyone to die because of me anymore!"

Yukio's eyes widened when he heard this. He remembered his own reasons…

~X~

Yukio sat on the ground, his face buried into his hands as he sobbed.

"I'm s-scared… I d-don't want to see those scary t-things anymore!"

"Yukio…"

Yukio looked up to see Father Fujimoto kneeling before him, placing a hand on his head in a comforting manner.

"… Come with Daddy and fight."

"Huh?"

"Don't you want to become stronger than those things lurking in the dark?" Fujimoto spoke calmly. "You can protect your sister and others."

"Protect… my sister?"

"Yeah."

~X~

"It's the same." Yukio said with a small smile.

Rin looked at Yukio. "Huh?"

"I became an Exorcist because of what Father told me… I wanted to get stronger." Yukio told his sister, looking directly at her. "It's the same as you."

'Same as me…' Rin thought.

"If you really want to become an Exorcist, this won't be the last time you'll hear what I just told you."

"… or just die."

The words rang throughout Rin's mind.

"Every Exorcist is after your life. You should be prepared."

Rin smiled gently at Yukio. "Yes, sir!"

Yukio gave her another smile and then walked over to the door, opening it up. "Sorry for making you wait. Let's continue with the class."

The seven students came into the room, looking around in shock and surprise… well, except for the puppet-kid and mysterious-hooded one.

"What happened?" The shy, brown-haired girl questioned.

"What's this?!" The boy with the red glasses said in shock.

Rin swung her now-covered sword over her shoulder, leaning against a desk with dog-Mephisto sitting on top of it. She looked around the room. The place was even messier than before. The desks were pushed all over the place, the pipes were burst, and there were remains from the hobogoblins on the ground.

"What the hell did they do?" The blonde-streaked guy muttered.

~X~

The sky was darkening and the air was turning cold.

Rin was standing with her arms crossed and her eyes twitching. She was looking up at the old, run-down dormitory. 'This place is freaking creepy…' She thought, shivering lightly.

"Hey, Mephisto…" But she trailed off when she realized that dog-Mephisto wasn't sitting at her side. "He left! That clown bastard!"

Looking back at the creepy dorm, Rin sighed and shook her head, thinking, 'Looks like I have no choice…'

Rin approached the entrance of the incredibly creepy dormitory and entered. As soon as she did, the lights flickered on.

"What the hell!" Rin exclaimed, jumping in surprise. "Oh my… I hate this place already…"

She used the sleeves of her black blazer to wipe her sweaty palms – knowing that if Yukio was with her, she'd be scolded for doing this – and reached into her pocket, pulling out a slip of paper Mephisto had handed her before he'd disappeared.

You're in room 602, Princess

Enjoy the dormitory!

~ Mephisto Pheles

Rin crumpled up the note and tossed it on the ground. She didn't even care – she was just annoyed now.

Scowling, Rin trudged throughout the dorm, looking for her room.

"602… 602…" Rin murmured to herself as she scanned the door numbers, not really paying attention. She stopped suddenly, having nearly walked past a door labeled 602. "Ah! Here it is!"

Rin pushed the door open, cautiously looking around. The lights were off inside the room, making it look as creepy as it felt. She stepped into the room – making sure to be careful so she didn't trip – and began feeling around for the light switch.

Someone tapped Rin's shoulder.

She screamed in a mixture of fright and shock, quickly tuning around and lashing out. She couldn't see whoever she was attacking because the room was dark and the windows were covered by the drapes, blocking out the moonlight, but none of that mattered to her.

The person, who had tapped her shoulder, caught one of her fists and held it tightly. This only made Rin try to hit the person harder with her other fist.

"Rin! Rin!"

The voice was familiar…

"Yukio!" Rin gasped, slowly lowering her one fist. She stopped struggling, too.

The lights flickered on – Yukio had turned them one – and Rin could now clearly see her brother.

"I-I… what are you doing here?" Rin questioned him.

"Are you surprised?"

"Surprised?! You fucking scared me!"

Yukio ignored her and headed over to the windows, opening the drapes on them. He then turned to face her. "I got them to bend some rules to let me room with you." He was smiling. "Also, we're the only ones in this dorm."

Rin was staring at him, blinking.

"You're dangerous, so I have to keep a close eye on you."

"What…? Keep an eye on me! What the hell is this? A freaking prison?!"

Yukio nodded his head. "Yes, and I'm the warden."

"No, no, no!" Rin was shaking her head. "I want my own room! This dormitory has only us, so I should get my own room! I can take next door."

"Sorry, sister, but you can't."

Rin stomped her foot. "We haven't shared a room since we were ten, Yukio! I'm a teenage girl, I can't share with you!"

"You want to become an Exorcist, right?" Yukio said, still smiling. "Then you should be able to bear with this."

"You little…" Rin began, but then she stopped herself. "Alright then! Bring it on!"

Yukio gave her an appraising look. "That's the spirit! Now, let's do today's homework!"

"What… h-homework?"

Yukio sighed. "Weren't you listening?"

"Sure, I'll do it! If I do it, you'll be happy, right?"

"Yes."

Sighing, Rin trudged over to one of the desks and set up her work. She sat down with Yukio standing over her shoulder, watching her closely as she did her homework.

'This is misery!"

~X~

'This is soooo boring…' Rin thought, resting her cheek against her hand. She was barely keeping her eyes open as she struggled to pay attention to the teacher. 'I thought cram school would be more interesting than this…'

Rin's eyes slid shut. 'I'll just take a little nap…'

"Okumura-san!"

Rin's head slipped and slammed into the desk. She then jumped to feet. "Y-yes!"

"Pay attention in class!"

"Yes, sir," Rin nodded her head.

With that, the teacher turned back to his lesson.

'Oh jeez…' Rin thought as she sat back down, stretching out her legs and leaning back in her seat. Her cobalt-blue eyes followed the teacher, but she wasn't really paying attention to him. 'I can't handle this textbook crap!'

It was a late Friday afternoon – almost the end cram school – and Rin was utterly exhausted and bored out of her mind. She'd only been attending cram school since Monday, and she was already annoyed with it. Rin just wasn't good with any of this school stuff – sitting in a desk, writing notes, memorizing things, and then taking tests. It was her worse nightmare.

'Oh gosh… actual school starts after this weekend!' Rin thought in horror. She most certainly didn't know how she was going to manage normal homework and cram school homework.

"… and that will be all for today." The teacher announced.

Rin was the first one out of her seat. She swung her sword over her shoulder and quickly left the room. She hurried down the hallways of the cram school and picked a random door. Rin opened the door with her key and was greeted with the campus grounds of True Cross Academy.

'I'm sooo going to talk to Yukio about this textbook shit. I need some in-the-field action to learn!' Rin thought as she jogged through the nearly-empty school grounds.

What made cram school even more brutal for Rin was the fact that it went so late. When Rin had been in middle school, she used to take a nap as soon as she got home to the monastery after school. That was something she wouldn't be able to do when normal classes started.

'And all this homework Yukio keeps giving me is brutal.' Rin scowled as she finally reached the abandoned boy's dormitory. She entered the run-down building and hurried down the halls.

"Yukio~!" Rin shouted cheerfully, opening the door to room 602. Maybe she could convince her brother to help her with her homework.

Rin, however, was greeted with an empty and dark room.

"Where is he…?" Rin mumbled to herself, switching on the lights. She noticed a note on the desk, which was addressed to her. She headed over to the desk, picking up the note to read it.

Rin,

I have a briefing to attend. I probably will not be back until late.

Do not leave the dorm room and do not cause any trouble. AND do your homework, Rin!

Yukio

"So four-eyes is gone, huh." Rin said, crumpling the note up into a little ball and tossing it into the garbage can across the room with pretty good accuracy. She grinned. "Yes! I am so not doing my homework!"

Rin quickly stripped herself of her school uniform and changed into some fluffy, dark blue pajamas. Smiling happily, she shut off the lights and crawled into bed.

'I'll just get up early tomorrow morning and do my homework then…' Rin thought as she drifted off to sleep.

~X~

Soooo, that's the end of this chapter! Once again, sorry for how long it took me to update. Also, I'll be leaving the polls up for a few more chapters probably before taking them down. So everyone vote! I WILL NOT count votes in the reviews!

Sorry for any silly grammar mistakes!
