Now, I know I have quite a few stories that I've written (many of which I'm working on and are also on-hold) however I've had this idea for quite some time and I just HAD TO write a fic on it. I don't see any crossovers AT ALL about Detective Conan/Magic Kaito crossed over with Blue Exorcist. There's probably only two at most I've seen, but are only one-shots.

So, as I said above this is a AnE crossover with the DCMK. I got the idea when I saw the Magic Kaito opening and thought to myself that it'd be great if there was a crossover between my two favourite Anime/Manga. You'll see how I got the idea in this first chapter.

Also if you think I revealed a bit TOO much in this chapter tell me in reviews. Remember this is the first chapter, so there will be more and most likely I've got more stuff planned to happen later on.

Hope you enjoy.

P.S. This takes places AFTER the Camping Trip Arc, so everyone knows about Rin already and I just decided to set it here because ... I forgot most of the stuff that happened later and this is an easier place to start😅. Also just in case there are people who haven't read the Manga yet too.

P.P.S I added an extra bit before the scene-cut where Rin introduces himself to Kaito since I thought that makes sense of him to do as he's a very cheerful guy and Kaito would like to have a friend at a new school.

Chapter 1

New Student

~~~ 4:12pm - True Cross District - True Cross Academy - Classroom ~~~

It was just after the day classes had finished. A teenage boy with messy, raven black hair was running down the halls of True Cross Academy; dodging students and nearly tripping over his own feet as he came to the door he needed to be at. It was wooden and had an intricate design detailed onto its surface.

He opened the door, huffing as the entire class turned to him; which only consisted of six students with the teacher included. "Sorry, I'm late!" He exclaimed, hurrying inside and sitting in his seat at the front of the room, taking the sword bag off his shoulder as he did so.

The teacher narrowed his teal eyes before sighing and fixing his glasses. "It's fine, Rin." He turned to the now closed door and looked down at his watch nearly hidden under his True Cross uniform, irritably.

"Umm, Sensei?" The gruff voice of the spiky-haired blond-brunette at the back of the classroom made him look up. "Class started fifteen minutes ago ... why aren't you...?" He gestured toward the empty blackboard causing the teenage teacher to sigh again.

"I'm trying to be patient, Suguro," He told the student while folding his arms in annoyance.

"Why?" Rin asked, tilting his head in confusion. "We're all here so shouldn't you start?"

"Well..." He walked around his desk, leaning on it. "I was called up to the Director's office and he told me that we'll be receiving a new student."

"What!" Suguro shouted, surprise clear in his voice.

"This late into the semester?" A calm voice spoke up beside the grouchy teen.

The teacher nodded his head, frowning. "Sir Pheles told me that he's not here to become an exorcist, but to learn how to defend himself in case he comes in contact with a demon. He lives in the Tokyo region of Japan, I hear the crime rate is pretty high there, so it could be assumed that some demonic activity is involved."

"Why can't he learn self-defence normally?" Rin asked his younger brother causing said teenager to sigh in response.

"Rin, he wants to learn about demons to protect himself and those around him just in case exorcists are preoccupied with something else," Yukio explained to the confused Rin.

"That seems pretty reasonable," a female voice spoke up. "However how did he learn about demons or the Academy in the first place?"

"Sir Pheles mentioned he's had a mashou for a while, so he's known about them and just thought they were a part of some sort of magic spell. How he knew about the Academy ... I can only guess that the Director informed him about it."

"Wait, magic? Why would he believe in that?" Suguro scoffed, rolling his eyes as if the idea of magic was ridiculous.

However before the teacher could continue to answer questions on the new student; the door opened, but no one was waiting there. Yukio blinked and frowned, wondering if someone was playing a trick on him until a large smoke cloud covered the wooden stage he was standing on. All the students stood up, ready to grab a weapon or run and Rin already had his sword in his hands.

As the smoke vanished a teenager with messy, chocolate brown hair stood where the smoke has once been with a large grin on his face. "I'm Kuroba Kaito! I'll be joining your class!" He did a light bow; summoning a dove by clapping his hands together and letting it go.

His hands had been covered by a large array of flames.

Blue flames.

As he had opened his hands and let the dove appear from said flames, cooling down as the bird flew off.

The bird flew around the classroom, but the reaction was what surprised the teen. A gun was instantly pointed at his head by Yukio as he turned his head to face the teen with confusion etched on his face.

"What are you really?" He growled out through clenched teeth.

"Huh?" Kaito asked, sounding annoyed and slightly offended. "I'm a magician." He pointed towards the flying the dove, holding his arm out and it instantly flew to its master's arm. "That was magic." He stroked the dove's head, earning a coo from the animal.

Yukio still had his gun trained on Kaito's head as the magician tickled the dove's belly this time. "No, what I mean is what the dove appeared from?"

Kaito turned his head back to face Yukio, head tilting in confusion.

He didn't understand what the teacher was talking about.

He'd made doves appear before and people has been amazed, but why were these people shocked ... scared even?

"THERE WERE BLUE FLAMES COMING FROM YOUR HANDS!" Suguro shouted, pointing a hand at Kaito, anger written across his face as he glared at the magician.

"Bon, calm down..." A shaken voice beside the Suguro spoke up, causing him only to growl back in annoyance.

Kaito turned to face the gruff voice and shrugged. "Yea..." THe magician replied with an impassive expression. "...what's wrong with that? It's magic!"

The whole class stared at the new student as Yukio finally lowered his gun, putting it in his holster and sighing. 'Don't tell me the reason Sir Pheles called him 'special' like Rin is because...' He took in a deep breath and let it out. "I'm going out for a bit. I need to talk with the Director." He turned to his class and glared at them. "Nobody do anything stupid - that means basically you, Rin."

Rin blinked, pointing at himself as if to emphasise this and his brother narrowed his eyes at him before turning back around.

The teenage teacher left the classroom and then there was suddenly silence as everyone kept nervously staring at the new student. He looked around the room for a seat and shrugged, deciding to find one. He wondered down the isle, sitting down behind Rin and putting his bag down on the floor beside him.

Kaito took out a deck of cards, setting them on the desk before delicately creating a castle of cards.

It was an efficient way to use his time whenever bored.

It also allowed him to hone his skills a bit.

He was just about to put the final card on the castle when a chair backed into his desk, causing his nice card castle to collapse. He groaned and looked up with slight annoyance at the culprit. The messy haired teen that was named Rin stared down at the cards before giving him a sheepish grin as an apology.

"Sorry about that. I wanted to say hi and apologise for my brother's behaviour before," Rin said and the half-demon noticed how Kaito's facial features didn't change much a part from a small smirk.

"Don't worry about it. I'm used to having guns pointed at me!" Kaito replied and even though it was meant to be a light-hearted joke the other teen took it the wrong way.

"You have? Why?"

However Kaito decided to dismiss what Rin had asked and went back to his cards.

The half-demon couldn't stop thinking about the blue flames he had seen when the dove had appeared.

Had Kuroba been targeted by exorcists because of those flames?

Is that why he was here too?

He bit his bottom lip before extending his hand out to the other teenager; who looked up, noticing the hand and the wide smile on Rin's face. "I'm Okumura Rin. It's nice to meet you!"

Kaito blinked a few time before grinning back and taking the hand and nodding. "Kuroba Kaito, nice to meet ya too!"

They let their hands fall a part as Kaito went back to his cards and Rin watched.

Maybe this new student could be his friend ... if he was like him?

'He thinks the flames are magic though...' Rin thought to himself as he watched the other teen carefully start over from scratch with his cards. His eyes carefully wandered over to the dove, standing close by its master's side and the half-demon frowned. 'Its ... not even burned ... how?'

~~~ 4:38pm - True Cross District - True Cross Academy - Office ~~~

"Sir Pheles!" A man's lime green eyes glance over towards the door where Yukio had burst in through before going back to eating his instant noodles. The teenager walked up to the desk that the man was seated at and slammed his hands down. "I don't know what the meaning of this is, but I refuse to have Kuroba in my class!"

The Demon King stopped eating and lifted his head up to look at the young teacher with an eyebrow raised. "Why is that, Okumura-Sensei?"

"You never told me that he was a demon!" Yukio exclaimed, glaring at the man in front of him.

Mephisto stared back at Yukio before he burst out laughing causing the teen to narrow his eyes into a hard glare. "Oh my! He's not a demon!" Pheles wiped a stray tear away from his eye before grinning at the teen. "At least not yet anyway."

Yukio's expression changed instantly from anger to shock as he stood up straight and stared at the man. "Y...You mean he's...?"

"Just like you and Okumura-kun? That would be a 'yes'," Mephisto answered the question that Yukio was about to answer.

The young teacher swallowed what had been building up in his mouth. "Sir Pheles ... we saw the blue flames that came from his hands when he summoned a dove. He believes it to be magic..."

The Demon King stared at the teenager for what felt like a few minutes. When a defeated sigh left the Demon King's lips as he set down his half-eaten noodles, clasped his hands together on the desk and stared at the teenager. "You and Rin-kun ... are not the only two half-demon sons of Satan."

"We're not?"

"No. Actually there are two others; twins just like you two, but a year older. That would be Kuroba Kaito and his younger twin brother." Mephisto bent down, opening a drawer before taking out two files and handing them to Yukio. "Kaito-kun stayed with his birth parents while his twin was sent to live with a family friend. His parents believed that if they could first teach Kaito-kun how to control his flames then he wouldn't be a danger to others."

The young teacher's eyes scanned the file, frowning at the information written on it. "Which made him believe it to be magic. He was raised by Kuroba Toichi; a famous magician," Yukio spoke up, reading what was written on the file.

"Correct. He has also perfected something called 'pokerface'." Yukio gave Mephisto a confused look and the Demon King grinned. "It's an expression that allows him to keep all of his emotions in check."

"So, what happens if he ... breaks?" Yukio asked, sounding worried.

"He's still human, so if someone were to use that fact against him..." Mephisto closed his eyes before opening them again, narrowed. "...he'd be human no more. He'd be just like Rin-kun - a demon that used to be human."

Yukio stared at the Demon King, swallowing. "So then ... keeping his emotions in check with this 'pokerface' is his...?"

Mephisto nodded his head at Yukio's unfinished question. "Seal? It is." He narrowed his eyes at the teen. "Okumura-Sensei, I also allowed him here for his safety. Satan is after him just as much as Rin-kun. He doesn't know about himself yet, so keep it that way until you can explain it to him."

Yukio stared at the Director, lowering his head and nodding. "Yes, I understand." He handed the papers back and head out of the office with a smirking Mephisto watching his movements.

His eyes gazed down at the papers, grinning like a shark. "Well, Kaito-kun, let's see how long you will last."
