AN: Basically, this story starts at the very end of episode 1 of Ao no Exorcist. Everything's the same, except Fujimoto never shows up to save him.

In a small back alley

Astaroth, whom had possessed the body of the young boy Shiratori, was down on one knee before Rin, extending his hand out to him, expecting him to grab it.

"My prince, My name is Astaroth, King of Rot. Our Lord has long since awaited your return, let us go to him together," spoke the demon king, in a calm tone. Rin was staring between the flames that covered his body and the deformed man with horns in front of him. He could barely get out his words.

"Y-Your, ….Lord?"

"Yes young price, my Lord is awaiting your arrival." The demon king, growing only a tad bit impatient, grabbed the young prince's hand and brought him to his feet. "We must hurry before the Exorcists arrive…" Astaroth muttered under his breath so some disgust when he reached the word 'Exorcists'.

"Wait!" Rin yelled, trying to free the demon's grasp on him. "Where are you taking me? What are you!? Why am I so important!?" Rin, unable to get away from the demon was being dragged through many different alleyways.

"WHAT!? You mean to tell me you know NOTHING of your lineage?" Astaroth let out a sigh and continued, "Figures. Those damned humans hate everyone and everything that isn't from Assiah." Astaroth continued dragging a confused Rin until the reached an abandoned warehouse.

"Assiah…?" Rin, even though panicking at the confusing situation, couldn't help but to stop and ask what the demon meant by 'from Assiah'.

"You will see soon, my young prince. All will be revealed, when Lord Satan welcomes you home!" The demon king couldn't help but let out a laugh of unmeasurable amounts of joy. He had, at long last, found the missing prince! The one whom had eluded the best demons for the better part of 15 years! It was a momentous occasion!

"S….Satan….." Rin whispered quietly to himself. Although he wasn't religious in the slightest, you didn't have to be to know that Satan was the worst known demon known to man. Rin realized suddenly, because sadly it took him awhile to put things together, that this thing dragging him along, was planning to take him to Satan! Rin couldn't believe it! He knew this just had to be a dream! It had to be! Demons weren't even real! They were just made up fairy tales! But Rin couldn't seem to deny that deep down, this Astaroth person was telling the truth. He also couldn't deny the fact that he was basically a walking blue candle! Although the flames were slowly dying down.

"My young prince, it won't take long for word of you awakening to get around. It will soon reach Lord Satan's ears. When that happens, he will open the glorious Gehenna Gate for us to return to him!" Rin noticed that in all of his ranting, Astaroth had loosened his grip on Rin's hand. With a quick and unexpected yank, Rin was able to rip his hand free and he took off running.

"Young Prince! What are you doing! Lord Satan has searched for years for you! I'm sorry, but if you won't come willingly I will have to take you to your father by force!" When these words left Astaroth's mouth Rin suddenly realized a few things. For one, that Astaroth was running after him, and gaining on him for that matter, at great speeds. He also realized that instead of referring to him as 'Lord Satan' he had said 'Your Father', only confirming what Rin had pieced together in his mind. And lastly, he had realized that while the demon king had led him down all the alleyways, he hadn't been paying attention as to where he was going, so he was officially lost.

"Dammit!" He cursed under his breath. Rin tried running around every corner and jumping over every obstacle, to hopefully make the demon chasing him stumble or slow down. But Astaroth was still gaining on him. Suddenly, when he turned a corner he was confronted by a mob of dead dogs. They all smelled of horrible decay. Rin, trying to just ignore the dogs and keep running was soon tackled to the ground by a few, and then pinned by the rest. By now his blue flames had gone out, little did he know that demons were afraid and hurt by them. He squirmed and struggled underneath the mass of dead animals, but couldn't get out before Astaroth had caught up to him.

"Prince, why do you run? Why do you try to run from your lineage? Your family?" asked Astaroth, not out of breath in the slightest from chasing after Rin.

"The old man and Yukio are my family! I'm not a demon; I am NOT the son of Satan!" screamed Rin. However, it was futile. With a simple gesture from Astaroth, the dogs backed off of Rin. Rin tried to scramble to get to his feet and run, but by then Astaroth had re-grabbed Rin's hand. "Let me go yo-you, Demon!" At this little outburst, Astaroth couldn't help but to be amused.

"Young Prince, you and I are one of the same. You are just as much a demon as I am, and just as much of a demon as those ghouls," He said gesturing the towards the dead dogs. "However, your a lot smarter than those things, they have very simple minds you know." Suddenly, all the ghouls erupted in giant, blue flames. Rin stared at them in awe and fear. 'They look just like the ones that had came out of me….' He thought to himself. Out of nowhere the dogs started to bite each other and bleed a strange dark blood, that looked more black that it did red. Soon the blood started to mix together on the floor and a hideous creation came forth.

"Lord Satan has gotten word from one of my minions! How splendid! That was much faster than I had first anticipated!" Astaroth patiently held the squirming prince's hand as he waited for the Gehenna Gate to finish forming. All the while Rin was screaming things such as "HELP ME!", "SOMEONE! PLEASE SAVE ME!", and, "DAD! YUKIO! ANYONE!" into the sky.

"Time to meet your father, young prince," said Astaroth as he threw Rin into the Gate. Rin continued to scream and flail, but to his great disappointment, nobody had heard his cries for help. Rin was slowly dragged down into the dark, his vision becoming cloudy, and his mind shutting down. Soon he passed out and was swallowed by the abyss that had formed.

Roughly 5 blocks away, 1 minute before the Gehenna Gate had opened

"Dammit Rin, why couldn't you have just stayed home and accepted being grounded? Now you've got be fighting all these demons, just so I can get to you," Said Fujimoto to himself. He held his cross pin as he recited verses to kill the hordes of demons trying to stop him from proceeding. However, Fujimoto just calmly continued to walk by as if there weren't hundreds of demons in his way. He continued to chant his verses until he finally heard something over the growls and grunts of the demons.

"SOMEONE! PLEASE SAVE ME!"

'That sounds like Rin!' thought Fujimoto. Instantly Fujimoto took off in the direction of the scream, hoping he wouldn't be too late.

"DAD! YUKIO! ANYONE!" Rin's screams seemed to get more desperate and loud as Fujimoto grew closer, running as fast as his body would allow him to. Over Rin's screams, Fujimoto heard another, darker voice.

"Time to meet your father, young prince." Fujimoto, already running as fast as he could, could do nothing to stop what he saw as he rounded the corner. A demon stood in front of the Gehenna Gate looking down at it, smiling. He turned around when he heard Fujimoto, looking at the priest with his unnerving eyes. Fujimoto was fixated on the Gehenna Gate that was in the middle of the alleyway, but then he realized that in all of the heads, lay an unconscious Rin, who had sunken down to the point of only being able to see his dark blue hair. In an instant Fujimoto knew he couldn't save his son as he was dragged down into the world of Gehenna. "Oh, how interesting. It seems you have impeccable timing, . Too bad, our prince has now returned to our Lord's side." Mocked the demon king.

"Shut up.." said Fujimoto under his breath while in a state of shock.

"What was that?" taunted Astaroth, in a way that a victory may speak to a loser of a competition. "I couldn't quite catch that." The demon laughed as he stared at the crushed looking priest in front of him.

"SHUT UP!" Raged Fujimoto screeched. He ran straight at the demon, reciting a prayer as he ran.

"Evil is in their hearts. Oh Lord, give to them according to their works and the wickedness of their inventions. According to the works of their hand, render on them their reward. Thou shall destroy them and shall't (AN: In all actuality thats how Fujimoto says it in the English dubbed anime, I looked it up :P)build them up. Blessed be the Lord. You have heard my supplication, The Lord as my helper, and my protector, Thou shall perish!" While he was reciting his verses the demon king, Astaroth, was doing everything he could to stop him. Throwing punches left and right, but Fujimoto, even though in a rage, was able to grab the demon king and throw him to the ground. As he finished the prayer, the demon left the young boys body, but that didn't matter to Fujimoto. All the mattered was that Rin was taken away and it would be very hard to get him back. Fujimoto was contemplating jumping into Gehenna himself, but before he had the chance, the Gate abruptly closed, as if it had never been there in the first place. Although he was in some dank alleyway with some an unconscious teenager with him, Fujimoto couldn't stop himself from crying at the lose of his son….

Down in the depths of Gehenna, The Palace of Satan

'So he has finally arrived has he? Excellent…..' thought Satan. 'Now there is the matter of retrieving him from wherever he fell… He should be close by, but I can't be certain...' Apparently he had started to talking to himself out loud and his servant, Sebastian, didn't say anything, but looked at his master questionably. Realizing he had started mumbling aloud, Satan made extra sure to keep his mouth shut, not many knew of his plans. 'I don't want the general public to know of my son's arrival. They will lose respect for him if he is not shown off as a cold blooded demon. The way he is now, most would probably kill him.' Satan knew he shouldn't care if the young boy were to die, but sadly he was an important part of his plans. Satan, sighing loudly, said to Sebastian,

"Hey, Sebastian, do you know if my son, Astaroth, has returned yet? I need to have a word with him."

"I do not I'm afraid," said the demon to his master, who stood obediently at his master's side. Just then a demon, resembling that of a coal tar, but roughly 100 time bigger, entered the room and soared over to Sebastian. It mumbled something in its demon language before it let the room. "It would appear that Astaroth was forced back to Gehenna for a moment, but it was brutal. He was exorcised by the Paladin. In a rage he had been able to gather enough strength to repossess his host, and he is currently going to seek his revenge." Satan sighed at the imputance of his son. His mission to retrieve the boy was complete! He had no more reason to stay in Assiah. 'No matter,' thought Satan, 'I will just have to send someone out to retrieve my youngest son.'

"Sebastian, I need to ask a favor of you. You see, there is this pesky little human teen who has crossed over to this realm. I need you to find him and bring him to me…. alive."

"As you wish, your highness. However, I must ask, why not just let this boy die? Is he someone special to you?" Sebastian asked, hoping to understand why this was important to his master.

"I guess I can't really hide it from you any longer, but if I tell you, you must swear to me you won't tell anyone, or I WILL burn you." Sebastian, now standing in front of his master, rather than by his side, bowed and said,

"As you wish master, I will not tell anyone or anything about this conversation." Satan sighed with a little frustration and said,

"You going to retrieve my half-breed son, Rin. He has lived in Assiah for 15 years, but I have finally found him. I don't want anyone to meet or see him yet, because he still acts human. Nobody would respect him or acknowledge him as my son. And how can anyone trust a human to run my army?"

"I see," said Sebastian, making sure not to allow any emotion into his voice, "then I will be off. I will return with the prince alive master." Finally raising himself from his bow, Sebastian left Satan's throne room and set out to find the prince.

Down in the depths of Gehenna, The Fog

Rin awoke very groggily. He had a massive headache and felt like he was going to throw up. After just lying on the ground for a few minutes, Rin finally opened his eyes and sat up, slowly. He looked around not knowing where he was. 'Damn, what is this place? All there is fog as far as I can see.' he thought silently to himself. This is Gehenna, out-lander. Rin, startled by the strange, deep voice stood up quickly and got into a fighting stance. He shouted,

"Who's there? Show yourself!" Rin turned around, searching for where the voice came, but the voice just seemed to be amused. Hahaha! You humans, so silly to watch, yet so fun at the same time.

"I said, SHOW YOURSELF!" Rin screamed, allowing his anger to slip into his voice. Along with his anger, he had let slip the blue flames again. "Shit, not this again…." said Rin, quietly. Ahh! I see! You must be the rumored son of Satan! I never thought those rumors were true! But here you are, in the flesh! How wonderful! However, you seem almost human! That won't do! That simply won't do at all. Rin suddenly realized that the voice didn't seem to come from any particular direction, but instead spoke straight into his mind. 'Damn if he speaks through our minds I won't be able to tell wheres hes coming from! He could be anywhere in this fog...' thought Rin, 'I shouldn't run though, who knows if I'm gonna run into another….' he paused in his mind for a second, still trying to grasp the idea of demons, 'demon.' he finished.

Well it's far too late to be avoiding demons now my boy, your right in the middle of one… said the voice, slyly.

"Dammit! Get out of my head!" Shouted Rin into the fog, still looking back and forth, trying to distinguish anything that he could in the fog. Don't you understand yet? I AM the fog! I may not have a solid body, but instead have a gaseous one. It's what allows me to slip in and out of people's minds so easily. Rin was shocked by the new fact, and was frankly a little frightened. He decided his best option was to run as fast as he could to try and escape the fog. Rin, without hesitation, bolted from his position in a random direction he had chosen. HAHAHAHAHAHAHA! Well now I'm REALLY amused! As Rin was running through the fog he felt something stop him dead in his tracks. He couldn't move his arms or legs for some reason. He tried to move them, but they were constricted by something. He was alarmed to see that his wrists and ankles were entirely encased in small bits of fog. The fog started to move and along with it,it pulled Rin, who was now suspended in the air, fighting with all his strength to break free. While I did say I didn't have a solid body, that doesn't mean I can't manipulate solid objects with my fog. You are not going anywhere my young prince. After struggling for a few more minutes Rin knew he couldn't escape and began to calm down. As he started to relax while being there, suspended in air, his flames died down as well.

"What is it you want with me anyway! Just let me go!" Rin pleaded, trying to reason with the demon, rather than using brute force. I assume you've been living in Assiah for a long time…. Otherwise you wouldn't look so human and everyone around here would know about you.

"What the hell is with this whole 'Assiah' thing! I don't even know what that is! Astaroth mentioned it while he was dragging me here, but I still don't understand!" I see….. Well then, let's have a nice little chat shall we? You don't seem to be going anywhere anytime soon. Rin grunted, but didn't respond. The mysterious voice began telling Rin everything there was to know about Gehenna.

In Assiah, The Monastery

Fujimoto had returned to the monastery, but wouldn't say a word to his associates. He quietly walked to his office, slamming the door behind him. He just needed some time was all; time to process what had happened to his adopted son. 'I should have told him earlier! I should've prepared him for a day like this!' Fujimoto thought, angrily to himself. He sat down in his chair looking at his desk. It was littered with paperwork, some paperweights, and two pictures, both of his sons. He looked gloomily at the the pictures, saddened by his thoughts. Suddenly, Yukio entered his office.

"Yukio! I thought you were at the school, unpacking!" Said the startled Fujimoto.

"I was, but then someone called me and told me… what happened….." Fujimoto was stunned for a second, remembering that he hadn't told anyone Rin was taken away, but he then realized that he had told one of the priests he was going to LOOK for him. Returning without him and in a depressed, unresponsive state, the priest (AN: IDK what the names of the 4 priest people, who live at the monastery with Fujimoto, so i just put priests.) was able to put one and two together.

"We can't tell anyone about this you know, if word gets out I could be in a lot of trouble, but not only that. If the Vatican find out that the son of Satan was alive AND is now in Gehenna, they will shoot him on sight! No, we have to keep this on the down low. However, we ARE going to need some help….. Dammit, I may need to talk to Mephisto about this…." Yukio just stood there silently as his father rambled on about saving Rin. His mind was going 80 miles per hour. He hadn't fully believed that Rin was gone, but know he knew for certain that he was gone…. Yukio started to cry a little…. realizing he had failed to keep his brother safe…..

In Assiah, Outside the Monastery

"So this is where that pathetic Exorcist lives," said Astaroth, talking to himself. He glimpsed up to the sky to see the sun fleeting into the distance. Soon would be an opportune time to strike. He gathered tons of his minions from around the area, preparing for his attack. "This will be fun!"

1 Hour later

Yukio had since returned to the room he and Rin had shared, trying to hold on to his memories. He didn't know if he could go on knowing that Rin had been taken to Gehenna and may never return. 'And if he does come back, he may not be himself anymore…. Will he even be human?' thought Yukio. Before Yukio could ponder his thoughts, He heard a large crashing sound. 'What was that?! Was there a car crash outside?' He ran quickly to the main hall to go out the front door, but saw that the sound had not been from outside. A huge 16-wheeled truck had plowed straight into the front of the monastery! Ghouls started to walk in slowly, most of them being dogs. Some demon mushrooms started to grow on any flat surface they could find, trying to cover the entire main hall. Fujimoto and the others were already in the room fighting what looked to be a human possessed by a demon. Yukio drew his pistols and started firing rapidly at the demon mushrooms. 'I can't shoot that guy yet! My pistols are filled with lethal bullets! I need to empty out my cartridges and reload them with some that are filled with tranq darts.'

"Damn you Exorcist! This is what you get for exorcising me!" roared Astaroth.

"Dad! What is this thing?" yelled Yukio, as he finished emptying his gun.

"It's Astaroth! He was the one who took Rin to Gehenna! Afterwards, I exorcised him, but it looks like all I did was make him angry." Fujimoto explained. Suddenly, Astaroth took in a gasp as his demon senses started tingling.

"What…. is that?" He said, momentarily forgetting the battle that was taking place between his servants and the Exorcists. "That presence….. I have felt that before…..that's the young prince! Why do I feel his presence!? I SENT HIM TO GEHENNA!" Thinking Rin had someone escaped from Gehenna, Astaroth became enraged and started to head in the direction of Rin's presence. "He's underneath that alter isn't he!" yelled Astaroth pointing to the big alter the Exorcists were standing near. Yukio, a little confused thought, 'But Dad and the others said Rin was...' Without a word, Astaroth ran from the building, appearing to flee, but his minions were still there. Without wasting anymore time Yukio snapped back into reality and continued killing the demons. As the number of demons decreased, the Exorcists believed the battle to be over, but they were wrong. Astaroth drove a minivan straight through the wall of the monastery and into the alter. Along the way, Astaroth managed to take Fujimoto by surprise and rammed into him, sending the old man flying. Fujimoto hit the wall hard and slid down it, onto his back. He was bleeding from his nose and mouth and needed serious medical attention.

"DAD!" Cried out Yukio, as he rushed to his father, leaving Astaroth to the others.

"Yukio! Don't worry about me! Stop Astaroth! Hes sensing the Kurikara sword and believes it to be Rin! If anything that sword may be MORE important than Rin himself! It's our only hope of Rin remaining human! GO!" Yukio was conflicted, but in the end left his father, broken and bloody, to try and stop Astaroth. Astaroth stepped out of the van and, with a single foot, kicked it towards the four priests. Most of them were hit by it, but one managed to avoid it. However, he was only an aria, and not one capable of Exorcising a demon king, so he called out,

"Yukio! Stop him! I can't do much to help you, so I'm going to get Fujimoto and the others out of here!" Yukio didn't reply. Instead he just nodded in the priests direction and chased after Astaroth who had gone down the now revealed staircase.

"My young prince?" Astaroth asked, completely confused. All there was in the tiny room was a giant red chest. However, Astaroth knew that's where the young prince's presence was emanating from. He opened a draw in the chest to reveal a sword. He picked it up and knew that thid sword was what he was feeling, not the prince. Yukio, who had managed to get up behind the demon, shot him; emptying his clips into him. Astaroth fell to one knee, and screamed in pain. Well, in mock pain. His scream gradually died down into a laugh.

"Foolish human! It'll take a lot more that tranquilizer bullets and holy water to put me down!" 'DAMMIT! I put in the non-leathal cartridges! This is bad!' thought Yukio. Astaroth turned around swiping at Yukio, knocking him up against a wall in the small room. Yukio was unconscious before he even hit the wall. Now looking at the sword more carefully, Astaroth drew it from its sheath...

AN: BUMBUMBUM! Astaroth likes cars a lot, so he drives them into people's houses. That's gonna be a recurring habit of his, I decided :P Please review this and tell me what you liked, didn't like, could use improvement, was spelled wrong or worded incorrectly. I haven't done much of this stuff in the past, so all criticism helps!
