Author's note: Hey. This is my first fan fiction. I decided to write about Ao No Exorcist because it's my second favorite anime! Sorry that it's short. I know it's starting off a little slow but it'll get better, I promise! None of the characters belong to me, they belong to Kazue Kato. The rating is T for now, it'll change because this will be a MxM story. If you don't like, don't read please! Enjoy :3. Italics are thoughts. AU & OOC.

Trouble on the First Day

Rin stood at the gates of his new school, peering at the three story building with his younger twin brother at his side. Is this going to be his final school? He hoped so. "Nii-san." Rin briefly glanced at his brother, waiting for him to continue. "Ano," the younger male shifted, "if you get expelled from this school too, you'll be sent away, so please, please try not to get in any trouble?" Yukio looked at Rin hopefully as the elder bit his lip and gave a slight nod. "Okay, well let's get going." He tugged on his brother's sleeve and made his way toward True Cross Academy.

The halls of the school were mostly empty. I knew nobody would be here at this kind of time. Rin sighed silently. "Yukio, where is the office?" At the mention of his favorite place in the school Yukio smiled and gestured to a flight of stairs at the end of the hallway. "Just up those stairs." "Why is it on the second floor?" Yukio looked at Rin's puzzled expression and giggled. "Does that even matter, nii-san?" The elder grumbled and slowly followed his confusingly excited brother to and into the office.

As he entered his name was heard from a room off to his left. "Okumura Rin?" It was a male's voice. "Yes, I have his schedule right here. May I ask why he's transferred here a month into the school year?" "Um..the..principal knows why. Thank you Mr. Tsubaki!" With that, Rin watched as his younger brother came stumbling out of the room. He stood up and left the office with his brother on his trail, holding his hand out with a single sheet of paper. Rin scanned the paper. "Are you in any of my classes?" Yukio shifted and folded his arms. "Nii-san I told you that due to my grades I was made a second year student. Don't you listen to me when I talk to you at –," The raven-haired teen tuned out his brother and looked past him to see a student glaring straight at him. The guy had a mess of brunette hair with a big streak of blonde in the front and was accompanied by two other males. One had a mop of light pink hair and the other had, well, no hair.

"NII-SAN!" Rin's attention was pulled from the bigger male and his posse as his younger brother slapped his chest. "This is exactly what I was talking about! I'm going to the library. Good luck finding your way around." Yukio turned up his nose and walked away, leaving his brother slightly shocked at his outburst. Rin's eyes traveled back to the brunette-blonde boy as he openly laughed at him. He could have sworn the he heard him call him an idiot and his face burned as he swiftly turned away from them and walked up another flight of stairs to the third floor.

He looked out of the windows as he strolled pass to the last flight of stairs and noticed that more students were filing into the school. Guess school is about to start soon. Checking his watch, he realized there was about 15 minutes left before the first bell rang. I should be looking for my homeroom class… Just as the rebel was about to turn around, he spotted another flight of stairs. But I'm on the top floor…? Oh! That must be the roof. Hn, I have enough time to catch a nap. Rin darted up the stairs and threw the door open, confirming his suspicions. Before him stretched the roof of the school with ledge outlined by a tall fence. Rin walked out onto the roof and sat beside the small building, getting comfortable in the shade. He sighed in content and closed his eyes, swiftly falling asleep.

Two Hours Later

Rin shifted and squinted his eyes as a bright light interrupted his nap. He sat up abruptly, ready to argue until he realized that it was the sun, hanging over his head. Oh. It's just the sun. False relief washed over the twin before his breath caught. Shit! The sun's that high?! Checking his watch Rin realized that it was now 10:15, the break time for the first year students. Okay! I have math in the next five minutes...I only missed two classes. I can make this work! He tried to convince himself. God, Yukio is going to kill me. Rin picked up his backpack and rushed down the stairs while looking at his schedule. Math, math, math. Ah! 3-C, right on this floor! He looked around frantically and saw Class 3-A. He ran pass that class and the one that followed to find his math class. He slid the door open and quickly took an empty seat to the back just as the bell rang.

As if on cue the door nearest the teacher's desk slid open and in walked a woman who looked no more than 20. She had a big bust and bizarrely colored hair. The teacher gave the class a bored look and she looked around the room at each face, a smirk appearing on her lips when her eyes landed on Rin. "Okumura." Rin stood up from his slouched position in the chair. "Yes ma'am." "I'm surprised you came, your first and second period teachers said they hadn't seen you today." The class' gaze shifted to Rin and he avoided everybody's stare. "I, uh. I just. Well,-" "I don't care. Come introduce yourself to your class." His eyes trained on the floor as he walked to the front of the classroom and stepped up. "Um, my name is Okumura Rin. I am 15 years old...and I transferred from, well. That doesn't matter." Rin bowed his head to his classmates. "Please take care of me." He looked up at the faces of his classmates and immediately noticed the pink head of hair he saw earlier, in the seat beside his. Why hadn't he noticed before? He also didn't miss a pale girl with blonde hair staring at him intently. A blush crept up her face at being caught staring and she looked away quickly. I might not like this class so much, he thought as he took his seat and the class went by quickly with the busty teacher rambling on about equations Rin knew nothing about.

A few minutes after the bell rang a crackling sound was heard over the P.A. System. "Good morning, Academy. Please pardon the interruption but Okumura Rin please report to the principal's office. I repeat, Okumura Run to the principal's office. Thank you." More crackling before the system went dead. "Shit," Rin grumbled.
