Hello everyone that reads this. BEFORE YOU READ, there are a few things I want you guys all to know in advanced. This is so that you also know that I DON'T WANT FLAMES.

This is Amaimon X Rin, and while they are still guys in this (if you don't like boy X boy please leave) they ARE NOT BROTHERS. I will say this again NOT BROTHERS.

Rin's powers have slowly increased so that he can talk to demons regularly.

Yukio may or may not be a demon later on.

This story focuses on Rin and Amaimon's relationship, Yukio and Rin's brotherhood, and Satan being a little less evil than people think he is (will be explained).

Disclaimer: I do not own Blue Exorcist/ Ao No Exorcist.

I will try to update as much as I can, but really this is just to put my idea out there so I know if I should continue.

"My prince, why do you side with those disgusting humans?" a coal tar hummed as it floated contently around his master's head. The other coal tar around hummed in complete agreement trying to get closer to Rin. "Why do you desert us so?"

"Leave me alone." Rin growled making the coal tar whine as their instincts clashed. On one hand they always obeyed their master, on the other they always stay near their master. He groaned in annoyance, "Alright you can stay just shut up already."

"We only want what's best for you master. Its safer in Gehenna where there are many guards to protect you and teachers to teach you. The humans of this world are treacherous things that will kill you. We don't want that!" another coal tar whimpered nuzzling against the half-demon prince.

Rin was trying to actually get homework done for once, and just to spite him it seemed, fate made all the coal tar in the area to decide at once that it needed to be by Rin.

"They are correct young one, it would be better if you went home to Gehenna." An emotionless voice rang out making every one of the coal tar squeal. Rin turned to see Amaimon standing on his windowsill, nail in his mouth and staring at him. "It isn't right for you to be here in Assiah."

"What are you doing here?" Rin snarled reaching for his sword which laid right next to him. As soon as he moved the coal tar raced out of the room, they were scared of the amount of power clashing.

"Amongst other things, I was watching a clueless kid converse with pets." Amaimon sneered.

"They aren't my pets. In fact I'm pretty sure they aren't anyone's pets." Rin stood up. "So don't call them that."

"They're weak and useless while you are the son of Lord Satan himself. You're higher in rank and power than most full grown demons even though you have not come into your own powers. That has never happened before, even the other sons or daughters of Satan needed their own powers to become strong, some aren't even worth the food that they eat still. Because of your strength many demons will want to be noticed by you, it's only natural. Amaimon released his nail.

"What do you mean; I haven't come into my demon powers? I have shot blue flames at you and burned you." Rin's eyebrows furrowed in confusion.

"Those were inherited from your father, most demons get more than just some inherited skills. And even if you did not gain any powers or skills of your own Satan has many lesser powers that you can still inherit when they want to be made known." Amaimon tilted his head. "Did Big Brother Mephisto not tell you this?"

"No, big brother Mephisto did not tell me this. In fact he doesn't tell me most stuff. I only found out he was a demon because of the Vatican." Rin was still a little upset about that, and the fact he hadn't been informed before that Mephisto was a son of Satan. "Which reminds me, are you or aren't you a son of Satan."

"I'm not, but Satan says one day I will be part of the family. I do not know what that means though." Amaimon muttered the last part. "But I should continue with what we were talking about. When you do in fact get your own powers and learn how to use them, you may end up being second only to Satan himself. Of course if this happens you will be forced to fight Mephisto until one of you two submit."

"Any other useful information Mephisto conveniently left out?" Rin asked making a mental list of things to hit his elder half brother for.

"Well, since you're in Assiah any demon can and will challenge you for your title as prince of Gehenna. If they make you submit in a fight this happens." The king of earth gave something akin to a cringe. "It would be disgusting to have demons like that ruling Gehenna. Thankfully though, you're other brothers would never allow it."

"My other brothers?" Rin asked.

"Astaroth, Lucifer, Egyn, Azazel, Beelzebub, and Iblis. The other Demon Kings besides Mephisto and I. They are going to be in charge of teaching you control of your powers probably." Amaimon was still emotionless but Rin imagined that anyone else would be grinning at his clueless ness. "Otherwise you would easily lose."

Something inside Rin snapped, "I will not lose."

"Careful young one." Amaimon told him, "It is no good to get emotional; those emotions will hinder your ability to control your powers. It is also no good to listen to your instincts when you have no idea what they are really saying."

"So you want me to become emotionless." Rin sneered. He completely ignored the second part.

"No, I just advise you to get less excited until you know what you are doing." The green-haired one cocked his head. "It's in your best interest."

"Since when did you ever care about my well being?" Rin questioned. Mind you through this whole conversation he had kept his hand on his weapon at all times.

"As long as you are alive, I have someone to play with and Gehenna has a semblance of balance. If you were to be hurt a lot or Satan forbid killed. . . . your brothers would destroy everything." The green-haired demon said this as if it was a normal thing, which Rin guessed it was to demons.

"They don't know me." Rin frowned.

Amaimon looked almost confused, "Do they need to? You are their blood, one of their youngest brothers."

Rin almost laughed, "That doesn't mean too much, I mean yes it connects us but how much more can that mean?"

Amaimon bit down on his nail again a little harder than last time, "Maybe not much to humans but demons value blood ties very highly. And this is what I was talking about earlier."

"What do you mean?" Rin asked.

"You have no idea about your demon side. You do not understand instincts or actions that you do unknowingly. You do not know what a mate is, or understand the need for an alpha to guide you. How could you when all you know is what those humans taught you." Amaimon looked almost sad. "It is not right, even young demons know such things."

"Mate? Alpha?" Rin asked.

Amaimon sighed, "We have gotten off topic. I came here for another reason besides listening to you talk to coal tars."

Rin's grip on his sword tightened considerably.

"Not to fight." The elder demon sighed, "I've been going too easy on you because you think you can win any time that we fight."

Rin almost growled but Amaimon held up a hand to silence him.

The elder demon waved his hands and a new sword appeared.

Amaimon held it with both hands, "Lord Satan tasked me with bringing this to you. It was made under the unanimous decision of your family. This does not happen often."

"My family. . ."

"Voted to give you another weapon, knowing your little problem with showing your flames. They don't like you hiding who you are, but also see this as a chance to give you a sword worthy of a demon prince." Amaimon shoved it into Rin's arms. "Just take it."

The sword was beautiful to Rin. It was the same type as Kurikara. Its hilt was made from bone, carved with the words Et Non Flectetur. "Never bow." Rin muttered.

"Very good." Amaimon nodded.

The blade shone like diamonds and was as smooth as glass. Rin could see no marks of imperfection. Finally on the bottom of the sword was a glowing red gem, the gem reeked of power.

"That gem is made from your family's power." Amaimon informed Rin.

"Nice." Rin muttered, he had an undeniable and very scary attachment to the thing though.

It is very nice.

That voice. . . . It haunted Rin since the time he had heard it last. "Satan."

Aww, you can call me daddy if you want.

"Where are you?" Rin growled.

I'm not in Assiah my young one, so you cannot hug daddy yet.

"Why would I want to?" Rin looked really confused.

You will want to soon enough my young one. If not because you love daddy, it will be because I have done so much so that we can have a relationship. I mean it isn't easy agreeing with your brothers, and it is definitely not easy making a sword that won't try and take over you.

"I don't understand why you're giving this to me, I'm an exorcist. That family excuse only brings you so far." Rin looked to his companion.

The demons of Assiah tend to go a little crazy after a while. They think they can disobey the crown while they are there. I can't have that now can I?

"So you're using me." Rin summed.

What do you think happens when you 'kill' demons in Assiah?

"They die?" Rin guessed.

My poor naïve child. No, despite what you exorcists think, the demon does not die. It only comes back to Gehenna and gets scolded.

"You need a better punishment system."

You wouldn't be saying that if you knew our system. Anyway, I just felt I should let you know that this sword will sometimes create a bond between you and the demon this sends back.

"Why would I want that?" Rin asked harshly.

Amaimon cut in, "They can really help you when you fight the others."

"The others?" Rin questioned.

"Mistakes made from the clash of God's and Satan's powers. They try to kill demons and humans a like however no matter how many we kill they somehow spawn again; even though God and Satan have not clashed in years."

"What are they called?"

They have no names.

"Well why haven't you told the exorcists?" Rin asked.

Amaimon snorted, "They believe we are lying scum who want to stab them in the back. Nothing we say is ever the truth so why would they believe us in this."

Rin raised an eyebrow, "That's harsh."

"I'm done with this." The earth king sighed. "I'm bored. When you figure out who you really are tell me. Your family knows and I know, and the whole Gehenna knows. Yet you know nothing.

And with that the green-haired demon jumped out the window, disappearing. Satan was quiet, and his presence dulled. And Rin had a feeling that this had started something he would probably regret.

Outside Amaimon growled, "What in the name of Gehenna was that?"
