Authors note

Hey guys, so recently I have watched Ao no Exorcist (late I know). And soon I fell in love with Amaimon and Rin, only to be disappointed to find out that these guys aren't majorly shipped! So I have taken the opportunity to write a lengthy story about these two. Please keep in mind that I'm not a very good writer at all but I will try my best to entertain you guys.

This story will be focusing on Amaimon's and Rin's relationship. The two WILL be in character! Well I'll try my best to keep them in character, Amaimon will be tough as he wasn't in long enough to really analyse his character, so if you have any complaints don't be afraid to tell me.

So this story is rated M for later chapters, but this isn't just a fic with mindless sex, this story will have plot.

A special thank you to Demon-Princess-Astarte for doing a wonderful job at being my beta

PROLOGUE

Cold winds howled through the trees, making them sway against the darkened sky. It was one of those nights where the moon looked enormous, sending a luminous light over the forest.

"Shit."

The earth king swore, dodging another attack that was thrown his way. This time the attack slashed open his skin, blood tickling down his arm staining his green tattered glove. The attack had caused a large amount of rubble and dust letting the demon prince jump back from the battle zone to catch his breath. Hiding on one of the taller tree branches he looked down at his opponent as his wound knitted itself back together, his healing had become slower he noticed.

Now, Amaimon loved fighting; he thought of it as a game, it was always a great source of entertainment when he was bored. But what he hated was losing, and that is exactly what was happening right now.

There was no time to gain his bearings however when his exorcist located his hiding spot, jumping up the branches to swing his sword down on the demon. Amaimon's dodge wasn't as graceful as it usually would have been. Just barely dodging, his skin getting sliced again, he fell from the tree landing on his back.

Once he could gasp for air again after being winded, the demon slowly sat up, only to be pinned down again when the exorcist's sword stabbed him through his stomach. Looking up at the exorcist from where he threw his weapon he noticed his sight blurring. Fuck, was his sword soaked in holy water?

Now Amaimon knew he was in trouble, he didn't even have enough strength in him to let out his full power. What the fuck did he do anyway? He hadn't slaughtered anyone out of boredom, hadn't caused any mischief, hell! He hasn't even bothered his little brother and those insects since he's been back to Gehenna.

The stoic expression Amaimon always wore was replaced with fear; blue eyes wide, mouth agape. This was it, he thought. This wasn't how he saw his death; actually it never would have occurred to the demon that he would actually eventually die. Well that's what he deserved from his arrogance.

When the sword was pulled from his stomach to be held above the blonde smug looking exorcists head, Amaimon pondered where demons would go when they died. Perhaps a place more fun than this, a place filled with sweets and everlasting entertainment. Maybe that's what heaven was like and no way would Amaimon; after all he has done, be sent there.

Perhaps if he wasn't Satan's son, the circumstances would have been different. What kind of person would he have been? Good enough for heaven, or was he always destined for hell? Curiosity then took over his fear, smiling his toothy grin up at his reaper. "Come on!" He laughed, eyes glinting with excitement when he saw the sword slash towards him.

Before the sword could embed itself within the targets heart, a blue blur cut between the two. Amaimon couldn't see who it was straight away, even if the blue light should have been a dead giveaway. Vision focusing on the figure before him, Amaimon could only gape. "You?"

Rin was kneeling, his back towards Amaimon fully flamed and Kurikara in hands, stopping the others sword mid swing. "Just in time, Karaimon." He heard his half-brother grit between clenched teeth but before he could ask any more question or even irritatedly correct his name, his sight faded out to black.

Earlier that day

This was the last place Mephisto would have expected to be on a sunny Saturday afternoon. This was a day of relaxation, a day for him to rest after all his busy activities. But no, instead Mephisto found himself at the True Cross Headquarters trying to convince the Grigori that Amaimon had nothing to do with the current crimes he has been said to have convicted.

"What would his motivation be?" Mephisto tried, once again standing on trial after that incident with Rin long ago.

"We all know that the earth king does not need motivation for his crimes, he does it simply because he is bored." One of the Grigori replied.

This had Mephisto biting at his lip, trying to think of another explanation why his brother couldn't have committed the crime, a crime he wasn't entirely sure his brother hadn't committed. He hadn't seen Amaimon since he had went back to Gehenna a few months after that night the exorcist had tried to blow it up, but something told him that this wasn't something he little brother would do; it simply wasn't his style, no matter how bored he may have been.

The murder of 53 students had been the crime. The school had wards against demons and evil, but Mephisto had given him a key that would let him in, Amaimon still had it if he remembered correctly and even so he knew Amaimon was capable getting past those wards, no matter how long and complicated it got. But what confused him was that his brother wouldn't interfere with Mephisto's life unless Mephisto had called him or at least before paying him a visit.

"What is your evidence? I see the incident with Ernst Frederick has taught you nothing, to simply accuse a demon of crimes because of what he is. Mephisto sighed shacking his head. "I thought the Vatican had past this stage."

"Do not test us Mephisto Pheles, we are not accusing the earth king of anything, we had already sent exorcists to the crime scene in search of evidence."

What? "I see, And what did you find?" This was bad, usually he was prepared for trails like these, but he had nothing. The best he could do was keep a cool head and try and snake Amaimon out of this with charm and tricks.

"We have two witnesses that described the appearance of the perpetrator which resembled that of the earth king and have found the litter of candy wrappers at the crime scene." Amaimon would have killed the witnesses and removed all evidence; this was too sloppy for his little brother.

Mephisto's brows furrowed in thought. No, this just didn't make any sense. Even if Amaimon had been incredibly bored, he wouldn't have done something that would have interfered with Mephisto's work, especially something as big as this. He knew the consequences of interfering with the true cross order and worst, Mephisto himself. Plus senseless slaughtering just didn't seem like Amaimon's style. No, someone else was behind this he could feel it, but just who?

"If I could provide my own evidence to support that Amaimon is not guilty, would you let him go?" This was all he had to use, he had no tricks up his sleeves for this as of yet, all he needed was time to prepare.

There was silence before the Grigori turned to whisper amongst each other while Mephisto could only be patient.

"It is too late we have already sent the paladin to exorcise the earth king."

"If I could get to him in time?" He questioned, rising a thin eyebrow.

Silence again.

"If by any chance, you were able to stop the exorcism in time, we will allow it.

"Where was the paladin heading?"

Rin had been back at his hometown, it had been quite a while since he had been here. Since all the missions and training Shura had him doing he finally had some free time to himself, not to mention it was school break so he had come to the decision to come back and pay his previous home a visit.

Nothing really had changed, Rin noticed, even the air had the same feel to it. There was the park he and his brother would play at, his father usually accompanying them. The Kindergarten he used to attend, the supermarket he was first employed. Everywhere he would look, a new memory would awaken in his mind.

After a long day, Rin finally went to visit his father's grave, where he sat until then sun had almost disappeared under the horizon. That was when he felt his phone vibrate against his right thigh.

Snapped out of his thoughts, Rin made for his phone, sitting up from the leaves and grass. Blinking at the screen, he read the text message.

FROM: Clown

Okumura-Kun, I need a favour

And that is how Rin found himself knelt in front of an unconscious Amaimon, saving his life only by mere milliseconds. The bastard was lucky he was in the area and willing to even come. He thought of the ps4 Mephisto promised him if he went.

After some explaining and a heated argument, the paladin left, leaving Rin with Amaimon who lay on his side unconscious and breathing shallowly. Rin went for his phone once again.

Got him

He sighed after he pressed send, dropping to sit on the forest floor next to the bloody and bruised demon. It was weird (yet satisfying) to see the earth demon so pulverised and vulnerable, though shouldn't he have healed already? Rin pondered this when his phone vibrated.

FROM: Clown

Fantastic, my boy~

Good news too, you'll be keeping him under house arrest for 4 weeks

3 3

Rin blinked at his phone, re-read it, then re-read it again.

"WHAAT!?"

What the fuck? Rin repeated in his mind, pacing around the room for the fifth time. He had only meant to stay here for a day or two, but four weeks!? That is way too long, and to top it all off, he has to look after the stupid broccoli head until Mephisto finds some evidence to support him. Come on, the bastard obviously did it.

Sitting on the floor of his cramped hotel room, he watched as Shoppaimo- no, Amaimon (as Mephisto had corrected for him over the phone) slept in his bed. Mephisto had sent someone in the area to patch up his wounds, turned out he had holy water in his system, the reason why he wasn't healing normally, for a demon that is.

Left only in his pants and ripped green tights; bandages covered Amaimon's head, waist and right shoulder. His breathing was still shallow and the dark circles under his eyes seemed larger than usual. Again, this was too weird.

Rin scratched at his raven hair; standing up from the cold wooden floor he decided it was time for dinner. Maybe Amaimon will have woken up by then.

Hopefully the next four weeks won't be too unbearable.

He sighed once in the kitchen, who was he kidding, this was Amaimon.
