Hello~ I'm starting a new story, as you can see~ I've noticed there not too much fics or crossovers in the Blue Exorcist section. I wanted to add at least one story to it! So here it is!

It had been a long time since Naruko Uzumaki had been to school. Truthfully, she didn't even know why she was here, waiting at the renowned True Cross Academy to be enrolled in the Exorcist cram school. Of all the things she could have been with her experience, talents and money, she had chosen to go to a school training people to hate and kill the kind and kin of her beloved from the crib. It was irony at its finest. But, it was also new and exciting, something she had not experienced for a long time.

But no matter. The past was the past, and now it was gone. A new leaf had been turned. Perhaps, this generation would fare better than their predecessors, and leave behind their prejudice? She'd soon see.

The soon-to-be exorcist in training sighed and picked up her luggage, before walking towards the tall buildings of the Academy under the sweltering heat of the summer sun.

Today was a glorious day, of pure blue skies and lazy breezes, rustling the green leaves of the trees in the surrounding forest. The town seemed almost deserted, as everyone had stayed at home, trying desperately to escape the suffocating heat. Save for a few birds and a boy who walked the same road as Naruko, the scenery was bereft of any movement. The boy in question was dragging his feat slowly, like each step drained his already low energy, and his dark blue hair was matted with sweat. He was carrying a plastic shopping bag and was nosily sucking on a blue ice-lolly.

Naruko inwardly snorted at his lack of table manners; years ago, she would have eaten it the same way. But that was a very long time ago, and she had changed. When one lived a very long time, they usually went through moral changes. In this case, Naruko had lost a great deal of her optimism. Wars were constantly being fought all over the globe, and conflicts were ever-present. She'd even thought that, maybe, Pain wasn't so wrong after all, and that humans could never live in peace without someone forcing their hand. But she had a companion in her long suffering. One who'd been there from birth, and understood how she felt.

Though her snort was not as internal as her monologue after all, because the teen in front of her had stopped, taking out the lolly from his mouth and facing her with a scowl.

Naruko did a double take. Those eyes! They were like hers! The demon container's mouth opened and closed like a fish out of water as her mind whirled with all the reasonable answers that could explain her situation.

But it found none. Yuri was nineteen when she had died in a dreadful accident, and she had no known descendants apart from the cardinal, who was an old decrepit man. This boy, even if he had her eyes, couldn't possibly be related to her! But the resemblance was scary.

Meanwhile, Rin was glaring at the girl who had snorted at him. She was small and looked kinda weak with her thin arms and legs. Her whisker like scars on each cheek gave her a feral air that contrasted with her angelic blue eyes and sun kissed blonde hair. Her face was the picture of shock before his scowl was registered. Her face soured.

"What are you looking at?"

Her voice was hard, but Rin had fought down scarier opponents than a girl and wasn't fazed at all.

"A rude midget. "

"That's funny. I was looking at an aggressive, lanky bastard. "

Rin spluttered. He'd never heard a girl cussing before. Izumo usually used proper expressions like "idiot" and Shiemi… Well, Shiemi couldn't hurt a fly. Let alone start cussing like a sailor. Plus she had started it. Snorting at him like that!

"What? Never heard a girl cuss before?" she snapped, before looking at her wristwatch in a sudden panic. "Shit, the time! I have to meet the Principal at 11h30 and it's 11h 35! Move!", the girl spat before shoving past him and disappearing in the building where the principal's Office was housed.

The demon in disguise stared dazedly at the space where the girl had stood just seconds ago.

What the hell had just happened? Why had he just started an argument over a snort? Maybe she was just a normal girl who hadn't been looking for an argument, and had thought of something funny. And he'd become all hostile and aggressive, … like a demon. And despite his tail, his ears, his blood, he wasn't a demon. Not at heart. Rin resolved to apologize to the blonde haired girl should he see her again.

That solved, he put the ice-lolly back in his mouth, and shivering in delight at its glorious sweetness, he set off to drop the errand his spotty four-eyed bastard of a brother had sent him on.

Hmm. It was weird; he had a funny feeling that he had forgotten something,

Oh, well. It was probably something stupid.

"Come in," a pleasant voice invited from within the office. Naruko picked up her heavy bag, pushed the door open, and got ready to face whatever Mephisto Pheles had to say to her.

The bastard hadn't changed at all: same stupid purple hair with a single curl towering over the rest of his locks, same poisonous green eyes that always danced with hidden laughter and same mocking grin as ever. But his outfit… His outfit had reached new heights of childishness. A white top hat with a candy pink sash laid on his desk, and an umbrella with ice-cream styled decorations was leaning against the solid wood furniture.

The Principal himself was seated at the desk, hands folded under his chin as those damnable green yes of his looked her over. They widened when he realized whom he as looking at, and his mouth stretched in a grin that displayed his tiny fangs.

"Aah, Naruko-chan!~ It has been too long! How have you been, my dear?"

"Not long enough," growled Naruko. "And it's Uzumaki-san to you, Mephisto Pheles."

The Demon King pouted. "You're so mean Naruko-chan. Anyway. What brings you to True Cross Academy?"

"I wish to enroll here," Naruko blandly said.

The principal openly began to laugh. "You're jesting, Naruko-chan! Enroll in the middle of the term? And that's ignoring the fact that your mate is an extremely powerful demon. The Vatican will throw a tantrum the size of Assiah if they find out!"

"I'm willing to work hard and catch up. And that's if the Vatican finds out. Which I will make sure won't happen." Naruko assured.

The King of Time and Space sobered up and he twisted his goatee with his clawed fingers thoughtfully for a moment. "Very well. Here are the forms you have to fill up and your future timetable. The rest will be taken care of. "

Naruko's mouth dropped open. "You're letting me in this easily? I figured I would have to listen to you bitch about how dangerous this was, for you and this Academy, how you couldn't afford to take any risk, lest you be exorcised and bla, bla, bla…"

Her eyes narrowed. "There's a catch. There must be, you scheming bastard."

Mephisto's face was the picture of innocence and shock, which was doubly suspicious to those who knew he was actually a demon, and a strong one at that. Demons weren't born strong; they became strong by utterly annihilating their enemies and devouring them. "How could you think that of me? I'm genuinely offended, Naruko-chan! But you're right. There is a catch. I won't tell you about it though! It makes the games more entertaining that way. If you don't want to be a part of my game, well, you just have to leave…"

The girl's eyes flashed red and she bared her now sharp teeth, snarling. She needed information on "Your games! It's always about your games and your entertainment! I hate you!"

She stormed out of the room and slammed the door so hard, the windows behind him cracked. Mephisto Pheles, or as he was known in the human world, Johan Faust V, chuckled lightly.

"What an interesting development."

Back outside, Naruko was fuming. She hated being used! She knew Mephisto was hiding something from her. Considering other people's lives like a game! People like that, deserved to die. But, for a little while at least, Naruko would play along. She needed information on the Blue Night.

What could have caused Satan to go crazy like that? Yuri's death had been hard for them all, but it had hit the Demon King much harder than the rest. Maybe he had lost his sanity. The little she had seen of him, the demon had seemed childish, almost. (he still cursed like a sailor, though.)

What people considered aggressive behavior in demons, Naruko and the late Yuri had known to be rather oblivious, if not a bit hands on, curiosity.

Demons had limited understanding of Assiah, and like all living beings, were inquisitive. So, they possessed bodies to explore the material world and its many wonders. The slight hick in these otherwise pacific interactions with the human realm was that most demons did not know about life or death. They were immortal, living on even when they had been ingested by other demons or "killed" by exorcists. They reformed after a while out of their dispersed energy and could not understand why humans did not.

Of course, not all demons were like that. Like every civilization, they had their share of hate, war and cruelty. The stronger demons were usually drunk with power, and acted on their impulses, which quite often were devastating for he human world. An Impure King once decided to trek the world in its undiluted form, because he wanted to. Unfortunately, his true form had spread a virulent plague that had devastated human settlements and a branch of exorcists had been involved.

Last she had heard of him, he had been sealed, and his eyes, gouged out. But she was digressing.

There were pieces missing in her puzzle, and she had a feeling True Cross Academy might be just the place to find them.
