AN: So yeah, this is my first fan fiction... ever. Urgh I'm sorry if it isn't any good :S

Altered Vision

Chapter 1:

*Crunch* Amaimon knew he was in trouble now...

"You bastard!"

"I told you to move."

"Yeah and why the hell would I ever listen to you, broccoli?"

"So your tail doesn't get stepped on?"

"How about we have another fight and I can kick your sorry ass again, you seemed to be very interested in my powers ever since you first saw me... or maybe you're interested in something else about me?"

At that point Mephisto finally decided to step in, using his umbrella, he wacked both the arguing teens on their heads signalling for them to shut up. The two boys both snapped their heads to face Mephisto, glaring at him with steely eyes.

"If only looks could kill..." Mephisto smirked, walking back and plonking himself down in the cushioned office chair where he continued to cross his legs that now rested on the top of the cluttered desk. Nudging the documents and pens that were strewn across the surface, he then took it upon himself to stare intently at the teenager who seemed to squirm under the intense watch of the school's headmaster.

Realising that taking the argument further in front of Mephisto would lead to worse consequences, Rin and Amaimon silently brooded upon the sofa they now shared; Rin nursing his sore tail and Amaimon silently sucking on one of the lollipops he had stolen from Mephisto's desk earlier that day. Neither of them spoke a word nor dared to move a muscle due to the heated scowl they were receiving from Mephisto at that point.

As to why Rin and Amaimon were in the office in the first place was the work of Mephisto himself; he had ordered them there on 'important business' only to find that actually he had become extremely bored and decided it was time to show off his new Clannad kimono to the two manga fans that he knew of. The kimono was made out of white silk with pink cherry blossom and chibi images of Fuki and her beloved carved starfish pasted all over, Amaimon was jealous to say the least especially when it looked like the one Mephisto stole from him a couple of months ago: an eye for an eye though.

"So, was there anything else you needed us for?" Rin muttered, hoping that the change of topic would ease the glare Mephisto still had aimed at him and Amaimon.

Unexpectedly, the question drew a blank for Mephisto; "umm... nope, not really." Taken back by the statement, Rin glanced over at the other teen that was still situated on the couch next to him and was now shooting daggers into his brother's back, since Mephisto had began to stare aimlessly out of the large arch like window, he was completely oblivious of Amaimon's deathly glare and Rin's confused glances.

A short and curt tapping on the window pane caught the three males' attention, hanging there in mid air was another demon. This one was small in size, coal coloured fur grew in clumps on its mangled body and singed black wings sprouted from its crippled back, littered with tears; for its body mass, the wings did not look like they could support the flight of the creature and yet it hovered there, peering in through the glass with its' scrunched up eyes pointing accusingly at Amaimon.

"Urgh that little bugger's back" Amaimon grumbled rolling his eyes.

"Now now little brother, it's probably only here to deliver a message from the Vatican. There's no need for you to get your balls in a bunch over the matter... if you have any that is."

With that, Amaimon rose from his seat, once again glaring at Mephisto. Every step closer he took to the grinning demon caused the low growling emerging from his throat to increase in both ferocity and volume. Rin still sat there feeling highly uncomfortable with the whole situation, the need to flee from the room growing stronger with each slowly passing second.

A simple flick of his pale wrist was Mephisto's gesture of overlooking Amaimon's temper tantrum. Without paying the slightest bit more attention to the infuriated demon, Mephisto slid open the Victorian styled window allowing the airborne creature to enter the spacious room, whilst anonymously checking Amaimon for any sign of aggression towards the new comer.

The act only fuelled the raging fire burning within Amaimon's emerald eyes. But instead of acting upon the pent up anger, he found himself sitting back down only this time on a separate seat to the one he originally shared with Rin. Taking deep breaths to calm him down, Amaimon looked over at the younger blue eyed demon that seemed in a daze from the events that had only just transpired. He was obviously not accustomed to seeing demons working for the Vatican; it was quite a rare sight actually, especially when most people believed the Vatican hated the existence of demons and Gehenna. Most of the members wanted to rid the Earth of them completely - those born with some form of demonic trait obviously not accounted for.

Carrying on without even a glimpse in the direction of the Rin and Amaimon, Mephisto spoke directly to the lesser demon who hovered by the now open window: "Why have you entered these grounds?" he questioned with a stern yet mischievous voice.

Hearing the hidden malice in those few words sent shivers running up and down the demon's twisted spine, yet he answered with a rough but sturdy voice. "I was sent here to inform you of an upcoming mission involving the Akuma no Dokutsu."

Upon hearing the last three words Mephisto smirked; "The Daemon Caves? What could possibly involve them; they were completely sealed a few years back." Mephisto then chose to sit back in his office chair watching the messenger, a seed of doubt slowly but surely growing within his cat like eyes that now glowed with a luminous green hue. Whatever the problem was, it couldn't be that serious since the seals placed upon the caves were performed by some of the highest ranking exorcists in the area, Mephisto included. No demon had a chance at destroying or even just slipping past the seals, not even Satan himself.

"It seems there is some unusual movement between demons around the caves causing a sense of alarm between some members of the Vatican; that is all." Stuttered the creature: "If anything, the Vatican would appreciate a couple of low ranking exorcists to check the area out and report back to you, just as a way of receiving some experience on the field and to set the Vatican at ease."

Mephisto smirked at the statement, knowing exactly who to send on the mission...

Having not paid attention to the two other demons that were originally immersed in conversation, Rin and Amaimon exchanged worried glances after catching Mephisto looking at them through the corner of him eyes with a playful smirk tugging at the corner of him mouth. They both knew this meant trouble; probably for the both of them.

Choosing to avoid the look he was receiving from his brother, Amaimon went back to staring pointlessly at the numerous framed certificates and paintings that hung from the vibrantly coloured walls. Peering round now, Amaimon realised he could list off each one and where they were placed due to the hours of boredom he had spent in this office. The only other thing to occupy his demonic mind were the bags of foreign sweets Mephisto kept hidden - in a not so secret compartment - in that poorly treated desk of his. Mephisto would just become considerably pissed off at the fact that his stash of sweets were rapidly decreasing.

However, it was obvious to Amaimon that Mephisto treasured his life on Earth, being separate to the one both the brothers had back in Gehenna. In Gehenna they were either treated like royalty for being the sons of Satan, the strongest demon in existence, or they were challenged for their power by those envious of them and the status they gained for being born of royal blood. It was much more peaceful on Earth, to say the least. Amaimon's feelings of hatred towards Rin and his twin Yukio thrived upon this fact, raised on Earth and leading the lives of a human until their powers finally manifested. They had it easy.

Once Mephisto finished conversing with the smaller demon he turned in his chair to look straight at Rin and Amaimon. A glint of playfulness shining in his forest green eyes drew in the attention of the teens from what their minds were occupied with before. "If you had bothered to listen, you would have heard that a new mission has opened up."

With this, Rin's confused frown grew into that of a grin, hinting at the hopefulness swelling inside him at the possibility of being chosen to go, completely forgetting any thoughts on his previously painful tail. "Who is going on the mission then?" Rin spoke up for the first time since he had shouted at Amaimon for stepping on his tail. Little did he know, the decision had already been made and it wasn't one he was going to like.

Giggling slightly, which attracted weird looks from the boys that were both slouched on the sofas, Mephisto answered: "Well, the little guy over there did say a couple of low ranking exorcists, but that would be boring. So instead, I'm sending you two on this mission, together. Think it as bonding time between half-brothers. " Mephisto winked after announcing this, waiting for the explosive response he was expecting from Rin.

The winged demon took this as his signal to leave after catching a glimpse of two enraged looks from the teenagers Mephisto now acquired. Flapping his stubby wings, he disappeared out the window he had entered through; out into the fresh, spring time air.

Rin shot up, preparing to have a go at Mephisto for suggesting such a thing; whilst Amaimon remained glued to the sofa only rolling his eyes at his brother's seemingly ridiculous decision, and unwrapped yet another lollipop he had stashed in his pocket.

2nd AN: Any constructive criticism kind of review would be helpful especially if it is to point out any mistakes in this chapter. Ohh and I plan to update whenever I have time :D sorry if that means that there is a long wait for some chapters. GCSEs are a bummer!
