Satan was sat in his throne room, legs crossed with a book in hand. Suddenly the doors opened, he looked up to see who had interrupted him this time. Astaroth had walked into the room, followed by a flock of coal tars squeaking and skittering around his head. He seemed in a hurry. Iblis soon followed in behind him. Satan closed his book and placed it on the arm of his throne.

"What is it?" Satan looked at them both quite annoyed.

Astaroth stepped forward to speak.

"It's Rin, Father. He's gone. Coal tars by the service entrance spotted Amaimon leading him through the tunnels."

"Is that so?" There was a slight twitch in his eye; the book by Satan's hand was now burning away to nothing "And where is my son now?" It was unnerving how calm he sounded, but both Astaroth and Iblis knew otherwise and could sense his anger beneath the façade.

Iblis answered this time "We believe he boarded one of Samael's phantom trains…to Assiah."

"I see." He swiped away at the dust leftover from the book, taking a pinch of the leftovers and rubbing them away between his fingers. He uncrossed his legs and leant forward in his throne, voice a low growl "Well I suggest you go retrieve him before Samael gets his hands on him."

"How will we know where to find him, Father."

"There is only one place he will be and you know very well where that is. Now go!"

Astaroth and Iblis nodded and quickly exited the room, doors closing behind them. They only made it a few seconds before they heard their Father explode in anger. Amaimon was going to be in trouble if he decided to come back, but they both knew he'd hide behind Samael for now.

Although Iblis feared what he might do to Rin if they managed to retrieve him. That idiot pulling a stunt like this. If he lost control out there, they would kill him.

"We should team up, even if the Paladin is weakened that place is full of exorcists."

"What's the plan for getting him back to Gehenna?" Iblis questioned; a hint of panic laced her voice.

"I have a suggestion…" They both jumped at the sound of their Father's voice behind them.

After going over the plan Iblis and Astaroth left for Assiah. Satan returned to his throne with an angry grimace.

Rin had been ready to run up and happily embrace his brother on sight. But as he got closer and those words left Yukio's mouth, he froze. His mind thrown straight back into that dream and visions of his brother with a gun to him were fresh in his head. A dull throbbing started to form.

Yukio stood staring at the figure in front of him, unable to move. Out of fear or just shock he wasn't sure, probably both. The person in front of him hadn't moved or spoken a word since he had turned around and it was making him nervous. Surely Rin would've opened his big mouth by now.

"Nii-san?" He waited and still no answer "Answer me!" He accidentally let some of his anger for Mephisto slip through into his voice.

The figure flinched back. But they were interrupted by Father Fujimoto rushing out the door in response to Yukio's yelling. His eyes focused on the heart and a look a fear drifted over his features. Memories of the last time he had seen that heart and the demon it belonged to. He grabbed Yukio's arm and pulled him back, drawing a shotgun on the figure.

Rin's eyes opened wide at the sight of his very much alive father, he snapped out of his trance and fell to his knees struggling to hold back his sobs "Dad…?"

Shiro's breath hitched and he slowly lowered his gun at the sound of the familiar voice.

"…Rin?" he managed to croak out.

Barely a second went by before Fujimoto had put down his gun and ran to Rin's side. Dropping to his knees and holding the boy in his arms, he had to keep patting him down to make sure he was really there. Rin's fingers were digging into the priest's coat as he tried to reign in his own tears.

"I thought you were…I'm sorry—" Rin started but Father Fujimoto interrupted.

"I'm fine. What's important is you're home and you're safe." He gave Rin another squeeze "Let's go inside."

They started to walk towards the door, but the fear returned and Rin stopped himself. Father Fujimoto and Yukio both looked at him confused.

"Rin?"

"Is that…ok?" He looked at them fearfully "I mean I'm—I'm not—Crap, just look at me!" He pulled off his hood, revealing his new demonic transformation; his tail set itself free of his shirt. The looks of shock were evident on both their faces. Shiro nearly had to urge to get the gun again, it was like looking directly at Satan. If it weren't for the boy having Yuri's eyes, he'd be the spitting image. But he pushed down the fear, this was his son.

Rin could still feel it though.

He wanted to ignore this feeling, he wanted to go home with his dad and brother and act like a family again. Like the last two weeks never happened. But this feeling wasn't going to go away, his new body wasn't going to go back to being human. He wanted to know the truth before going forward. He wanted to hear the truth from the people that had lied to him.

"Do you really want a demon like me in your home? Or do you just want to keep me here until the exorcists come and get me?" The throbbing in his head was starting to get worse.

"Nii-san…"

"He told me Yukio, how everyone I cared about is an Exorcist. Even you!" He shot a glare at him "I was the only one in the dark about everything…I know…I know I was just kept alive and raised to be used as some sort of weapon…"

"That's not true." Yukio gave his father a questioning look, hadn't he had this argument before about raising Rin to be a weapon. "Rin listen to me; we are not handing you over to the exorcists. Come inside and we can talk about this properly." He looked into Rin's eyes, putting his hand on his shoulder. The throbbing in Rin's head didn't subside but he decided to go inside anyway.

They moved into the Monastery. Rin hesitated at the door, feeling the barriers in place against demons. They weren't strong enough to stop him but enough to make his chest feel heavy upon entry causing him a dull pain. It made him realise just how real this nightmare was.

The priests entered the room to see what the commotion was, and gasps could be heard as they laid eyes on Rin. Shiro shooed them out, for the time being. He wanted the three of them to talk privately and not overwhelm Rin with too much company just yet. They could have their reunion when all this was cleared up.

But Rin could feel the fear, he could feel the fear from the priests, from his Father and most of all from his own brother. They tried to hide it through the forced smiles but Rin's demonic senses just seemed to thrive on it. Satan had been right. He winced when a painful throb hit his head briefly.

"Nii-san are you OK?" Yukio looked at him worriedly.

"I'm fine…" He pushed his head into his hands, massaging the spot where the pain was worse. "Just a headache." Yukio and Shiro shared sceptical looks. It wasn't like Rin to get headaches even when he was sealed and human.

"How long have you been getting headaches?" Shiro asked carefully.

"They come and go. At least since…" They had been since he lost control in the arena, a sign of the demon struggling to get out. He wasn't sure if he wanted them to know about that just yet, they already feared him enough without adding an out of control demon to the mix. He just hoped he could hold it down until he calmed down.

"Since when, Rin?" Shiro gave him a serious look. Rin knew he didn't usually get headaches; his dad was suspicious already.

"It doesn't matter." Rin sighed. The more afraid of him they were the worse the headaches were going to get. "That's not what I wanna talk about right now. I want to know why you all lied to me my whole life about what I was." He was talking to both of them but was looking directly at Yukio. He still couldn't get over the fact his own twin brother was an exorcist and had known Rin was a demon this whole time. Yukio took note of the demonic eyes staring straight at him.

"I became an exorcist two years ago. I started training when I was seven."

"Seven! You've known since you were seven?!"

"No, he did not know about you. That came later."

"Nii-san, I've been able to see demons for as long as I can remember. I became an exorcist because I was tired of being scared all the time, I wanted to be stronger. I wanted to help protect you." Yukio looked at his brother with sad eyes. Rin didn't want to be pitied right now.

Rin winced again "But you still knew years ago, and you never told me." He moved his glare from Yukio to Shiro "Hell, you knew my whole life and never told me anything!"

"Rin, we were trying to protect you."

"Bullshit! If you were trying to protect me you should have told me the truth, so at least I could've dealt with it BEFORE Satan came to drag me to hell!" Rin spat; his tail lashed in agitation.

"I wanted to raise you a human, Rin. I wanted you to have a normal life. You were sealed for protection because if the Vatican found out, they'd have killed you."

"It would've been nice to have had a choice in what to do with my body before this whole mess. After getting dragged down there I was pretty much forced into drawing that sword…" He sat staring at his hands for a few moments. Shiro and Yukio stood in silence, this wasn't going well.

"Did you even consider that sealing my heart was hurting me…?" Shiro looked somewhat taken aback by this. At the time it had seemed necessary with how out of control Rin had been at birth, he'd never considered if it would hurt him in any way. "When he broke the sword… I can't even describe the pain I felt. But when I woke up, it felt different from before… it was like I was whole again. It felt good. It was like a part of me had been missing my whole life." Shiro and Yukio remained silent, worried glances between them.

"I hated him for it at first, but now I'm started to feel like he did me a favour by breaking that thing." Rin almost looked guilty, guilty for being thankful to Satan of all demons.

"Satan is an evil we need to be rid of, Rin." Shiro told him firmly.

"So I'm told…but he at least accepted me for what I am." Rin regretted those words but they were true. Shiro feared he was falling down the same path Yuri went when she left him that day.

"Did Satan do anything to you? What did he tell you?" Yukio broke in.

"He didn't do anything, really."

"You weren't tortured or hurt in any way?" Yukio asked carefully. Rin shook his head.

"Not by him directly. He threatened me once but mostly he just spoke to me. Told me about all of you…" He stared at Shiro as if looking right through him. "He told me how Yukio was an exorcist, and it was my fault that he can see demons." Yukio grimaced.

"He said you're all afraid of me because of my power. And you were only raising me to be a weapon for exorcists to use against demons and him." The hurt was obvious. He was still rubbing his temple where the headache had been throbbing non-stop.

"That's not true—" Shiro started but unintentionally Yukio cut him off with his own comments.

"Demon's lie Rin, you shouldn't listen to anything he says." Yukio said pushing his glasses back up his nose. Not realising his mistake, Shiro gave him a flustered look before shaking his head.

"I'm a demon, Yukio. Does that make me a liar?" Yukio's face dropped in realisation, too late to take the words back "Because the only person in this room that's been lied to is me! And it wasn't the demons that lied to me. It was all of you." Rin shot them both a glare. "Damn demons, eh Yukio?"

Yukio looked on in horror "Nii-san I didn't—"

"You didn't mean it? Sounded like you…crap" He started rubbing his knuckle into his head, this was making it worse. He needed to get out, he had to leave before he did something he'd regret.

"What's wrong Rin?" Shiro sat at eye level in front of him, when Rin looked up his eyes were flashing between his and a twisted spiral, like Satan's. Shiro froze, fear clear on his face. He quickly got a hold of himself putting his hands atop of Rin's shoulders.

"Fight it, Rin. Don't let him win!"

"It's not him… the part of me that was sealed…it wants out" He flinched out of Shiro's grasp, a growl escaping his throat this time. He stood up and staggered towards the main door.

"Nii-san where are you going?!" Yukio started to follow his brother reaching out to grab hold of him before a growl sounded and blue flames started leaking from his body. Yukio stopped in his tracks. Rin's demon now soaking up the fear in the room.

"This was a mistake; I shouldn't have come back. I should've just stayed in Gehenna, where it was safe. I was so desperate to talk to you, I jumped at the chance to leave when I found a way back and just wanted to put all this shit behind me…but it's not that simple – I can't. You were never going to accept me as a demon—ahh!" He fell to his knees "I—I need to leave before I hurt someone…" He stood back up and ran out the door, Shiro and Yukio followed behind. The rest of the priests soon appeared behind them hearing the commotion from the other room.

Rin staggered out into the courtyard, flames now spewing from him. He fell to his knees gripping hold of his arms. Shiro tried to get closer but the heat was too much, and the priests pulled him back, still recovering from the last incident. Yukio's hand was hovering over his gun but was reluctant to pull it on his own brother.

Shiro shot a look towards Nagatomo "Call Mephisto, now!" Without a beat passing, Nagatomo ran inside to make the call.

"Rin, calm down, please! We can help you!"

"How can any of you help me. You're human, you don't have a clue what I'm going through!" His face was a mix of untapped rage and fear of losing his family again.

Suddenly a wall of red flame appeared between Rin and the others. Two figures jumping down beside Rin. Iblis and Astaroth had come for him.

"What mess have you gotten yourself into now, Runt?"

"Iblis?" He almost sounded relieved, like he was happy to see her. Yukio and Shiro watched the exchange both curiously and warily. It wasn't a good sign if Rin was bonding with one of Satan's loyal demons.

"Father sent us to retrieve you. I warn you though, he is rather angry with you." Astaroth said with a hand on his shoulder. Rin bit his lip; it was a choice between unintentionally killing his family or facing an angry Satan.

"Nii-san, get away from them!" Yukio screamed out. Rin looked back fearfully, they were human, they won't accept him for the way he is. Not once they see him lose control. He had to stay with his own kind…

"Oh my, is that the other one? Hm… yes, I see the resemblance now, looks just like the witch." She said with a smirk. "A shame he's so human, we could've taken him as well." Yukio recoiled at the unwanted attention.

Shiro stepped up, blocking her view of Yukio "Not a chance, Iblis. Now step away from my son."

Iblis laughed hysterically "I'm sorry, your son? Mr Paladin, this boy is the son of Satan and a Prince of Gehenna. You have no claim to him anymore, you filthy human." She glared at him angrily. How dare he try to claim her brother as a child of his own.

"Is that his choice though? Or has Satan decided for him?" He looked at Rin, still on the floor struggling to hold on to his own conscious.

"Like it was his choice for him to be kicked out and shipped off to be Samael's plaything?" She gave him a knowing grin, Rin looked to him pained but Shiro just grimaced guiltily. "Just as I thought, I bet you've already made the call to him as well, haven't you?"

"It's not like that, I wouldn't have been able to protect him anymore – Mephisto was to provide protection for him when his powers awakened."

Rin's voice suddenly growled from beneath his flames "So it was always the plan to send me away?"

Shiro sighed, there was no making this situation any better "I had no choice, Rin."

The flames grew more violent the blue slowly taking over Iblis' own wall of red flames, much to her surprise. Rin's control was slipping, she knelt down to him and whispered in his ear.

"You're losing control brother. We have a plan but you're not going to like it. You want to come back with us, right?" Rin nodded weakly. He was still torn, but going back meant his family would be safe from him.

"Nii-san! Don't trust anything she says!"

Iblis shot him a glare, putting more power into the flames and making them reach higher.

"If you let Father in, he can make a gate for us to escape."

He looked at her shocked "What?!"

"Or would you rather stay here and risk killing your family? They've already called Samael; he'll bring exorcists with him. You'll be killed. Or trained to be their own personal dog."

"She's right, we won't be able to help you if the back-up arrives. Samael's power is second to Lucifer, and if he has Amaimon with him we are going to be outmatched." Astaroth looked at him concerned.

Rin was trying to take in all his options whilst still struggling against his demon, claws had grown on his hands and were dug into the dirt beneath him as if trying to ground himself. His tail lashing around behind him.

"But if I let him in, he won't let me go…"

"He will release you once you are safe in Gehenna, Father has a plan for you and it involves you with him, not as a vessel. Trust me." Iblis looked in his eyes, his pain was evident, both physical and emotional. He'd returned to his family, and still felt rejected in the end.

The other side of the flames Shiro, Yukio and the priests felt powerless. The intensity of the flames prevented them from getting any closer or even seeing what was going on now. Where the hell was Mephisto when you needed him. Any other time he'd poof in uninvited but when you actually want the bastard he was nowhere to be found.

"Dammit, he walked right back to us and we just screwed it up all over again. I swore if I saw him again, I'd make things right…"

Yukio stood in silence staring at the wall of blue in front of them before it suddenly disappeared as fast as it had appeared. They all looked in shock and confusion. Rin was still on the floor, Iblis and Astaroth by his side.

Yukio edged forward towards his brother, ignoring the other demons. But Shiro held him back, feeling something was wrong. The outside lamp burst, confirming his fear.

Rin stood up, flexing his hands whilst staring intently at them. Flames nestled on his head in the form of horns and the end of his tail which swished calmly behind him. With his claws he slashed both arms, allowing the blood to pool on the floor below him silently chanting to himself.

"Nii-san! What are you doing?!" He pulled his arm from Shiro and stomped to his brother, turning him around to face him, only to be faced with a menacing grin. Yukio turned to the blood on the floor which slowly was forming into something else. Yukio backed up in a panic, falling to the floor.

Rin looked up to Shiro and spoke with a voice that wasn't his "Shiro! Nice to see you again! You're looking well after our last encounter, aren't you? I'm sure Rin will have a better experience, less bloody." He laughed hysterically; evilly, which looked wrong with Rin's face.

"But don't worry, this is just a temporary measure to bring my son home, you see? I'll set him free again soon. But this does feel nice." He took in a deep breath, smelling the Assiah air. "It's been such a long time since I got to experience Assiah this comfortably. It's just a pity Yuri is no longer here with me, isn't it?"

Shiro nearly growled in anger.

"Trying to make amends by raising her boys though, weren't you?" He looked down to Yukio on the floor still shaking at the sight of his brother looking so menacing. "Look like Yuri, don't they? My precious Yuri…I may not have kept her in the end but I'm sure my son will make up for that." He sneered.

"Father we should go before their reinforcements get here." Astaroth put a hand on his shoulder.

Satan looked at his wrist as if looking at a watch that wasn't there.

"Yes, Samael is taking his time isn't he." He laughed "Get it? Time! It is a shame though I wanted to have a word with him and Amaimon for leading my poor boy astray. But I'm sure I will get that chance soon enough."

He looked towards the Gehenna Gate on the floor.

"Oh well, I had better get my troublesome son home and ground him for a while, that's what parents do, isn't it Shiro?" He looked to Shiro expectantly then gave him a toothy grin. "Or is hitting them an acceptable punishment? I'm so new to this whole parenting thing." Shiro's face blanched in horror.

"Maybe the next time you have a chance to speak to my son, you'll try to be a little nicer. Boy's going through a lot right now as you can see. Heh heh heh."

He walked into the Gehenna Gate with Iblis and Astaroth behind him. As they sunk down Satan turned to face them, smiling as he watched their looks of horror as Rin was taken from them again.

"Dear me, -" Everyone shot up seeing Mephisto sat on the wall by the gates of the monastery "—I can't leave you alone for five minutes can I, Fujimoto?"

"Mephisto! Where the hell were you?!" Shiro glared with fury at his friend, if he had come sooner, they might've been able to help Rin.

"I have been watching the events unfold. Waiting for a moment to step in. As it was, I was waiting for the poor boy to lose control so I could capture him till he calmed down. However, I was not expecting him to willingly allow Satan to take over…that was indeed disturbing."

"What?!" Yukio and Shiro yelled in unison.

Yukio had a panicked look on his face "He let Satan in willingly?! Wasn't that what he was fighting against the whole time?"

"No, -" Shiro said in a defeated tone "—he said before, it was him, the part that was sealed was trying to get out. So why would he stop that but let Satan in?"

"Because my dear Shiro, he can't control that part of him yet. According to Amaimon, he gets quite violent in that form. I imagine he let Satan in to stop himself from killing… well, you."

"But Nii-san wouldn't…" He trailed off, he saw the pain and anger in his brother's eyes, was he truly sure he wasn't capable of it?

"I'm afraid he wouldn't have been able to control himself like that. As for himself, he wouldn't hurt you, but his demon side is another story. So, I would've stepped in had it come to that. But once I sensed Satan, there was nothing more I could've done."

"What do we do now?" Yukio whispered to himself, Shiro overheard and knelt to put a comforting hand on his shoulder.

"We messed up Yukio, he came back on his own and we messed it all up…"

"Well, I might have had something to do with him returning."

"What do you mean Mephisto…" he glared at the demon "You said you weren't going to help us."

"I said I couldn't go to Gehenna and retrieve him. Not that I wouldn't help." He grinned "I had Amaimon pass on a package and show him a way out. Not that it matters now. Neither Amaimon or myself will be able to get close to him now that Satan has him back under watch."

"Why didn't you tell us? I might not have nearly mistaken him for Satan if I'd known he had a way out!"

"My dear Fujimoto, where would the fun in that be if I gave away all my plans."

"You're some piece of work you know that?"

"I am a demon, remember?"

Yukio remained silent throughout the whole exchange, staring at the place the Gehenna Gate had been previously. It was that night all over again, his brother had come back and he still ended up being taken to Gehenna, he was powerless to do anything. He was still too weak to save his own brother.

The demons emerged in Gehenna, and Satan returned to his throne room, the others followed behind. As he approached the throne, he gave himself a once over.

"Such a shame, it would've been fun to wreak some havoc up there for a bit. Still to see Shiro's face whilst I possessed the boy was quite priceless"

Blue flames exited the body and settled on the throne itself forming himself into the image of his original body again. Rin collapsed to the floor.

Iblis and Astaroth approached the unconscious Rin.

"What are you going to do with him once he wakes up Father?" Iblis asked carefully, she knew her Father's anger was testy and after recent events, she didn't want to be on the receiving end of that anger.

"My son and I are going to have a little chat. Now leave us. His training with you will resume tomorrow."

"Yes, Father." Iblis bowed along with Astaroth and left the room.

Satan circled the room around his unconscious son. Waiting for the boy to wake up. How to punish the boy though, he was already confined to the castle regardless. He would need more guards present at all times, outside his room and most certainly in the tunnels. Although Satan didn't think he'd go on another trip any time too soon, not after that disaster.

Satan still couldn't believe Shiro wasted his opportunity, Samael had practically gift-wrapped the boy for them and they still drove him away, probably even more so than before. He still had more work to do but it was coming on nicely, the boy had willingly let him in, which was a pleasant surprise.

There was a groan from the floor, as Rin slowly woke up. He opened his eyes to realise he was laid on a cold hard floor, trying to recall what happened. Then it hit him and he shot his head up.

"Dad?!" he shouted.

"Yes?"

That wasn't his dad's voice… he looked up to see Satan, looking around the room he noticed he was back in the throne room, in Gehenna. Then he remembered; he'd actually let Satan possess him in Assiah…he felt dirty.

"You didn't hurt them, did you?"

"As tempting as that was – to use your body to kill Shiro, no. It wouldn't have done any good for our budding father-son relationship now would it?" He gave Rin a sly grin, Rin frowned back.

"Didn't stop you the first time when you nearly killed him. You lied to me, you said he was dead…" Rin glared at him.

"I said he was probably dead, there's a difference. How was I supposed to know he survived?" Satan shrugged. "But was this trip not educational for you. Have you finally learnt that they will not accept you?"

Rin remained silent but nodded a response.

"Now, you and your demon ego need to merge. I will not have any more delay."

"I don't want to be that demon…" Rin growled back.

Satan grabbed Rin by the neck lifting him so he was face to face him. Claws digging into his neck drawing blood that ran down his chest. Blue flames flared up and surrounding them both. Rin could feel the heat but it wasn't burning him.

"You already are that demon! You just have no control. If you want to control it and not to kill your so-called family the next time you end up face to face with them, you will do as I say." He dropped Rin from his grasp, who rubbed his slowly healing neck.

"I should punish you for your little escapades back to Assiah" Rin froze, feeling the fear creep up his body "But I realise this is more Amaimon and Samael's doing. I believe your brother and Shiro rejecting you again is probably punishment enough, for now." Rin let out a sigh of relief.

"However, -" He paused; Rin held his breath "I will be taking over your flame training from now on. Iblis will be taking over combat training since I don't believe Amaimon will be returning any time soon." He towered over Rin in an intimidating manner. "It will be interesting to see what other powers you possess besides flames."

"Your training with me begins now, combat training will resume tomorrow." He gave Rin a menacing grin, sending a shiver down his spine.

"But I didn't think I was allowed to fight until I had control over my demon side…?"

"Yes, I did say that, didn't I." He stood scratching his beard thinking for a moment, before turned to Rin again, grin returned. "Well we best remedy that problem right away, hadn't we… my son?"

Rin stared at Satan, with a look of fear on his face for what he might become when this was over.

So a very fast update this time... clearing up my cliffhanger from the last chapter.

Hopefully its OK, I know some were disappointed Rin returned to Assiah so soon, but I've now cleared that up. I had these chapters more or less planned from the beginning it was just getting to them. Next chapter I'm afraid might take a while as I was planning a time skip to the camping trip, but kind of feeling I need a bit more of the in-between stuff really. I really need to include more Assiah related bits now since we've been in Gehenna for quite a few chapters.

If you have ideas please throw them my way! I have so far nothing for the next chapter xD.
