LLL- Soooo yep. First chapter! It's on and poppin!

Mephisto - On and poppin? Humans are so foolish

LLL- I'm not foolish. I'm a mad genius!

Mephisto - Oh, that must be why you don't own Blue Exorcist. *devilish smile*

LLL- You make me sad!

"Ahhhh!" Yukio tumbles to the floor with a thump "Rin! Could you put that thing away?"

He looks down at Yukio while sitting at his desk, umimpressed by the lack of authority. "Please tell me how you'd like me to put my tail away." His eyes are narrow as he watches his twin bother stand up.

"Tuck it in or something. Anything! I'm sick of tripping over it."

"I keep it tucked in all day. Here is the only place I can leave it out."

"Well keep it out of the walk way."

"Or you could just watch where the hell you're walking, four eyes." The demon puts his pen down on his desk and leans back with a moan. "Ugh! Now you've distracted me and I don't feel like doing my homework."

"You were never doing it to begin with."

"Was to!"

Yukio walks over and grabs his paper. "Rin these are flowers. You were drawing flowers...!"

He snatches it back, standing up. "They're.. uhm. holy herbs.. to stop demons!"

"I'm sure Shiemi will be touched."

Rin side glances to the floor. "Only you can touch her," he whispers under his breath.

"What was that?!"

"Nothing." Rin waves him off and starts walking to the door. "I'm going for a walk. I need some air," he calls back with his hands behind his head.

"It's getting dark. You should probably just stay in."

"Since when have I had a curfew?"

"Rin..."

"Quit your worrying. I'll be back." With that, he walks out of the room, down a few halls and out of the building.

Like Yukio said, the sun is setting and the sky holds an orange glow. Not many people walk through the campus when this time hits. His feet drag and he tries to focus his thoughts on something other than his worries. He's a demon. His friends are unaware of this and it's only a matter of time before people actually start to find out. Shiemi, Izumo, Shima, Konekomaru and Ryuji. What will they think of him when they find out?

He walks the paths of the steep campus. Along the way he catches a strange sight. Sitting on a nearby green bench he sees a purple dog. It's fluffy and well groomed while eating a hot dog? Rin raises an eyebrow and stops walking. He looks at the dog as it pays him no mind and walks closer to it. He bends to one knee and finally the breed looks him in the eyes. "Hey little guy. You're quite a strange one aren't you?" The dog seems to have an annoyed expression if that's even possible. Rin smiles stupidly at it showing all of his teeth. The dog eats the last bite of his hot dog and wipes his mouth with a napkin. Rin raises an eyebrow at the strange etiquette.

Suddenly, with the smell of flowers and blood, comes a puff of purple smoke. Mesphisto stands tall and grinning. Rin flinches back. "What the hell?"

"Quite the greeting." He tips his big white hat.

"A dog, really?"

"Yes. Really. Might I ask what you're doing out, brother?"

"Would you stop callin me that," he moans.

"Now why would I do that? You are my brother after all." Mephisto twirls his long pink umbrella and tilts his head with a smile.

"Why are you out?"

"I was enjoying a hot dog. I thought that was obvious."

"Weirdo." Rin turns to walk away.

"There seems to be a lot on your mind," the demon king says.

"And if it is?"

"You can come to my office if you want. Have a brother to brother talk to clear those thoughts." Mephisto starts to walk away, up a flight of stone stairs . "I have tea."

"Uhm..." Rin isn't sure about this. Why would a demon offer emotional help. Do demons even have emotions? When he clears the stairs Rin groans and ruffles his hair, torn, before chasing after Mephisto. He walks behind the strangely dressed demon for at least ten minutes before they actually come to the building that holds his office. They walk in, striding to his office in smooth steps.

Entering the office, it's exactly what Rin expected. The carpet is light purple, the desk is white and the room is spotted with way too many teddy bears fit for a demon. In the far corner of the room is a plushy couch with a tv and video game system. Rin runs to it quickly. "Whoa! Is this the X-Station Cube 340?! Yukio won't let me get one. He won't even let me have a TV!"

"What a shame." Mephisto poofs his clothes into pajamas and sits in his big pink chair propping his feet up on the desk. Rin sits down, not caring for the reason of him even being there. Just as his butt sits in the plush of the couch, a head drops down in front of him.

"That's my seat."

Rin flinches back from the unexpected appearance. He looks at the green haired man who literally hangs from nothing. He's completely upside down and looking Rin in the eyes with a lollipop hanging out of his mouth. He flips down and tilts his head. His attire is as strange as Mephisto's. Rin squints his eyes, looking up at the slender male from the seat. "I know you..."

"Well of course you do, brother."

"What? No... You're the guy from the amusement park, screwing with my flames."

"Yes. I had a lot of fun playing with you." His voice is neutral yet extremely sweet, almost like a kid. "I'd love to play again some day."

"Why you!" Rin lunges up, tossing his fist into a punch. As soon as he reaches the green haired demon's face, he is gone.

"You and Amiamon have met once in the past if I am not mistaking." Rin looks over to see the two together. Amiamon leans on the desk, his attention now taken by a knickknack of some sort in his hand. Mephisto leans upon the desk with his elbows and a sly smile spread across his white skin.

Rin's eyebrows furrow and his fist clench as he tries to keep his cool. "What the hell did you really bring me here for?"

"To ask a favor of you."

"A favor?"

"Precisely." He stands up and walks next to Amiamon who looks up at him.

"Brother. I am hungry."

"You're a demon Amiamon. You don't get hungry," Mephisto sighs deeply, clearly annoyed.

"But food still tastes good. I will return soon." At that he pulls out a tiny umbrella and twirls it through the air. The air becomes somewhat morphed like water and Amiamon steps through it, disappearing. Rin points his finger at the nothingness left of the other demon with a confused expression. Mephisto face palms before looking up at Rin.

"It's called an Infinity Key. He can travel willingly in and out of the campus as he pleases. Actually anyone who knows how to use it can do it. And he's not supposed to be using it for such unimportant reasons."

"He can get through the barriers? I knew you sent him on me at the amusement park!" It's clear that Rin is angry on the verge of flames.

"Well not really. He was bored and needed something to do."

"I don't see your damn point."

"You did a good job keeping him busy. As a brother I like to see him happy."

"Whatever." Rin swivels around, ready to leave the office.

"My favor..." Rin doesn't move, still wanting to hear the headmaster's reasoning. "I'm going away for a while and I need someone to keep an eye on Amiamon. He has a habit of causing trouble." Rin jumps around, looking at Mephisto.

"You're kidding, right? A babysitting job."

"I wouldn't call a full grown demon king a baby, but yes." After a few seconds of Rin running through his thoughts Mephisto smiles. "You have not run away yet."

"Why doesn't he just go back to Gehenna?"

"Father is being quite difficult is all. Plus he likes it here."

"Why don't you take him with you?"

"I'm going to meet with the True Cross Order. He might just ruin about everything and that might cause your death."

Rin rubs his hair, trying to think of more excuses and questions. "He can't take care of himself?"

"Well he can, but that might result in the death of hundreds and not to mention the trashing of my office!" Rin narrows his eyes at the President's poor prioritizing skills. Mephisto smiles at him once more. "I guess it's easier to say that Amiamon is one of the youngest of us Demon Kings. He's still a kid if anything."

Rin is silent yet again before ruffling his hair with a groan. "Why the hell am I even considering doing something like this?"

"Well," Mephisto shrugs, "it's in your blood. We of satan's blood find it hard to turn our backs on one another. He is our brother after all, if the help is needed, walking away is quite the challenge."

"Is that why you're helping me so much?"

"I guess you can say that."

Before Rin can say another word, Amiamon reappears. His arms are full of sweets and snacks. Three lollipop sticks hang out his mouth. Rin rubs his head. "How am I supposed to keep an eye on him. He's not going to just stay here! He has a key to everywhere."

"Do it like we do with you. You think hiding your demonic power is easy?" Mephisto snaps his fingers and luggage appears before him in the puff of a purple cloud. "Too-ta-loo." He pulls the bag out of the room.

"Hey, wait!" Rin calls, following after him. When Rin steps in the carpeted hall, Mephisto is no where in sight. "Damn him" he growls. When steps back into the office, Amiamon is floating cross legged in the air. Rin walks over to him and crosses him arms. "Looks like we're going to be close?"

"Can we play a game like we did last time?" His voice is neutral and his expression unchanging.

Rin shrugs his shoulders. "Sure, I guess."

"Oh goody."

He looks over at the green demon king, into his green eyes. Really he is quite adorable, there's no doubt about that one. It isn't until this thought that Rin nearly smacks himself in the face just trying to get himself together. "Soooo," Rin starts, breaking the silence filled with Amiamon sucking on lillipops. "Do demons sleep?"

"Yes. You sleep. I sleep. We all sleep. Mephisto lets me share his bed."

"Oh for the love of..."

"Don't curse," Amiamon states.

Rin rubs his face. "I don't even know how long that bastard will be gone."

"A week. Maybe two. Depends on how the Vatican is feeling."

"Well, see ya tomorrow."

Amiamon looks into the air and starts twirling around. "So you're just going to leave me here?"

"Yep," Rin says, inching towards the door.

"But I don't want to be alone." His voice holds a taunting tone, possibly teasing.

"Why the hell not?"

"It's boring!"

Rin sighs at this, disappointed that this is truly the best answer he's got. "Ok fine. I guess I can bring you to my place."

"Yay!" Amiamon wraps both arms around Rin's neck and he starts walking again. He is practically dragging the demon king's feet with every given step. When they are finally outside the air has a slight breeze to it, cooling the humidity. The sky is almost completely dark with a slight glow on the horizon and the atmosphere is light. Rin exhales and Amiamon looks up at him. "Is something wrong, brother?"

"Oh no," Rin states sarcastically. "I just have a demon king around my neck like an accessory that I need to watch for the next week. Everything is just fine."

"If it dissatisfies you why did you accept me?"

Rin's thoughts race and he feels a strange sensation run through his body. It is almost as if his demonic instinct is making him feel guilty, if that makes since. "You're my brother. My mind wouldn't let me decline. Satan blood line shit working against me I guess."

"Well I'm am quite happy you agreed." He releases Rin and performs 3 cartwheels until he is walking right next him.

"Why?"

"Because you are fun. Being in this place is so boring because I can't kill anyone. And Gehenna is even more boring. Mephisto never places with me. He's afraid we might destroy the planet."

Rin's eyes are wide now as his imagination concocts up what Amiamon might try to do with him. "Well... how about we just do human things."

"Human things? I don't think I have ever tried that before. I will consider it." Rin looks up at Amiamon to see him looking into the air, thinking. He always seems to have a curious look on his face. Like he's thinking about who he wants to kill next.

"Ok," Rin says, as they approach the building he and Yukio stays in, "we're here..." His voice fades when he sees someone standing in front of the door of his building. He yanks Amiamon to the side, behind a pole.

"Weeeee!"

"Shhh!" They both peek around it and look at the scene. Standing in front of the building is Yukio and Shiemi. "Dammit, I can't here them."

"You're a demon. Use your ears."

"I don't know how to do that yet!" He whispers back.

"They are talking about a date. What is a date, brother?"

"Shhhh!"

Amiamon says nothing more. After few seconds, Shiemi wraps her arms around Yukio and the two kiss deeply. Rin's mouth drops to the ground at this sight, his eyes not believing. He rubs them but the scene is still there. "Hmmm?" Amiamon hums. "They kissed. They are married?"

"No!" He hisses as quietly as he can. Rin tries not to yell against the ping of jealousy he's feeling.

"So this is just something humans do? Yes. I have heard about it."

Rin looks at Amiamon who stands behind him a couple paces. "Would you shut up?!" When he turns back around Shiemi is walking their way. He grabs Amiamon's shirt and yanks him to the ground so that they are hidden by a tiny shrub. The demon's green pointed hair sticks above the bush just barely but is easily camouflaged. He is practically laying on top of Rin, their face's too close to even breath.

"Is this what human's do?" His breath reeks strongly of sugar... and death. Rin pushes him off and sends him flying a couple feet. "Yaaaaaay." Then he hits the ground. They both get to their feet and Rin marches to the building, ready to give Yukio a piece of his mind. Amiamon glides a few paces behind humming an unknown tune.

When he is inside, Yukio is in the kitchen. He sighs with annoyed relief. "Finally you're back."

"Damn right I'm back!" Before Rin can say another word, Yukio pulls out his gun and points it directly at his face. Rin double back surprised.

"Rin," he says, breath uneasy. "Step to the side. There is a demon behind you."

Rin turns around to see Amiamon with another lollipop is his mouth. He puts up his hand defensively. "Wait! No, Yukio! It's my brother."

"I'm your brother, Rin. That is one of the eight demon kings."

"You don't understand. Mephisto asked me to watch him!"

"What?"

Amiamon blinks three times before titling his head as he looks at the gun pointed at him. "Do we get to play now? I like this game."

Rin turns and puts both hands on his arms, holding him back before he pounces. "No! We're not playing yet."

"Rin, what the hell is going on?!"

Rin grabs Amiamon's hand and leads him to the table. Kuro leaps on the counter. Amiamon looks at him. "A Ketto Shi, how adorable," he says in his normal, monotone voice. He stands up, walks over to the counter and starts to pet the two tailed demon cat."

Kuro bows formally to the higher power. "Hello."

"How cute you are. How big do you get? Let's see?" He taps the top of the cat and it grows into it's demon form. Rin and Yukio yell as they fall back and the table is broken by one of Kuro's paws.

"Kuro what the hell," Yukio yells.

"It wasn't me! I couldn't control it." Of course Yukio is the only person in the room that can't understand him. He shrinks back to normal sizes, somewhat exhausted from the unexpected change and use of power. The table and one of the chairs are destroyed, not to mention plates and various dishes are scattered across the floor.

Yukio doesn't even bother to stand as he glares at Rin. "Start talking!"

"Mephisto is out of town and he needed someone to watch Amiamon while he's away."

"Watch?! Why can't he watch himself."

"He just can't."

Yukio rubs his forehead. "And you said yes because...?"

"I couldn't say no! It's a demon thing. Our satan blood lines screw with our emotions."

"So tell me, how do you plan to hide him?"

"Bring him to cram school."

"Rin are you crazy!? He is a demon!"

"Yeah," he grunts, blue eyes looking to the side. "So am I."

"He'll be recognized."

"Not by the students. Anyone else, we'll just explain it."

"No. You will explain it. This is not going to be my responsibility."

"Fine," Rin grunts. "You'll probably be too busy with Shiemi anyway."

"What the hell does that mean?"

"Nothing." He grabs Amiamon's arm and pulls him. Without another word they leave Yukio in the destroyed room. Rin takes him up stares to the third floor and into a room.

"This is where you'll be," Rin growls, still angry.

"You are mad. Why don't you just kill him?"

He sighs deeply to this. "You can't just go around killing people that make you mad. Besides, he's my brother."

"Brother? Is he my brother too?"

"I don't know." Rin stands in front of Amiamon silent for a full minute. He can't seem to get the sight of Yukio and Shiemi out of his head. He knew Shiemi liked his brother but he didn't expect it to escalate that quickly. It's a relief his feelings for Shiemi didn't increase too much. When Ren snaps out of it, Amiamon is in his face, observing him curiously. Rin flinches back.

"Brother, you are bothered. It's because of that human girl. You want to do that?"

"Just go to sleep."

In a quick action, Amiamon bends down and connects his lips to Rin's. His mouth is warm and the taste of sugar is on his lips. He opens his mouth and bites down. This happens in a span of two seconds and Rin hops back grabbing his face. "What are you doing!?"

"You said you want to do what humans do. This is what they do, right? That is why you are sad. You want to do it."

"I... I.. Not like that moron!"

Amiamon pushes Rin's shoulder and pins him against the wall. He puts his body close and leans in again. "How about like this?" Rin's cheeks heat up and Amiamon dives in for another kiss. This time, in the midst of their interaction, he slides his tongue in. It's long and slick and nearly chokes Rin. With his demon strength, he pushes Amiamon away and covers his mouth.

"What the hell is wrong with you. You're my brother!"

"I don't see your point. Brothers help each other, right? I was helping."

Rin closes his eyes at the misunderstanding and sighs. "Just go to sleep."

Amiamon jumps to the bed in a flip. "Weeeee! Good Night Brother. I want to play tomorrow."

Rin nods, unable to look back at him while his lips are still tingling from the warm linger of the kiss. Deep down he knows, that if only for a second, his heart leaped.

LLL- My spelling and grammar is bad. Betas are welcome! ^_^First Blue Exorcist story. This is the longest first chapter I've even written in any of my stories. Normally their only about 1000 words. I'll write another chapter depending on popularity. Amiamon fics btw not the easiest to write. His character is so strange. Just sayin. But he's fun.
