Brought to you be the power of: Migraines! (giving me time off work to actually work on this T_T)

I am a tad unsure about this chapter so I'm hoping you like it!

Satan was in the throne room; a pure blue flame engulfing his throne. The large doors at the end of the hall opened to reveal Iblis and Astaroth enter the room. They stopped in front of the throne; the flames flickered a moment before forming into his humanoid form.

He looked at them, resting his head on the back of his hand.

"What is it?" He rumbled, echoing throughout the room.

They both stepped forward, determined looks in their eyes.

"Father, we were wondering. What are your plans now for the boy?"

He looked at them questioningly before they continued.

"You've succeeded in bringing him to Gehenna, even letting you possess him to bring him back after his escape. You've awakened his power and had him successfully merge with his inner demon. But for what? Your original goal was to steal the boy and take him as a vessel so that you could finally return to Assiah and take revenge."

"Plans change." Was Satan's only response as he sneered at them. Both Demon Kings stared back at the God of Gehenna still awaiting more of an answer. Satan frowned.

"I had many thoughts go through my head when I took over Shiro to get the boy. The last one was how weak he had gotten and I was unsatisfied with his death. It was too easy. But alas I had got the boy, I had got my vessel.

I have been mulling over my plans for a while since the boy was brought here. Having another being that can enter Assiah freely with access to the Blue flames is a strategic advantage on my part. IF I can get another body to inhabit. By choosing the keep him as a backup, I have put my faith in Lucifer's experiments. They succeeded once before; the next time will be more fruitful."

"But that was never a guaranteed thing when you first brought the boy here."

"No, I will admit I saw Yuri in him and I didn't want to destroy that just yet. Regardless of what happened back then. What really had me choosing to keep him was the news of Shiro's survival." A wide sharp-toothed grin formed on his face.

Both Astaroth and Iblis looked at him shocked.

"15 years and all I've wanted to do is get revenge on Shiro for taking Yuri from me. For stealing her. Because she chose him!" He roared; his flames flared as his anger rose.

Iblis frowned; it was always about that witch. The weak little human that had ensnared her Father, seduced him into passivity – at least until the end. But his obsession was still his undoing.

"So, all this is just revenge on Shiro?" Astaroth questioned; snapping Iblis out of her own seething thoughts.

"What better way to get revenge on him for stealing Yuri from me, than to steal his own son from him – and have that son refer to me as his father."

"But the boy is your son, not his—" Satan flared up, Iblis flinched.

"I am fully aware the boy is of my blood!" Satan growled "But the priest raised him, was a father to him and is still seen as a father by him. That is what needs to change. I want to tear his relationship with my son apart from the inside out."

"So that's why you won't take him as a vessel. You want him to reject the priest and refer to you as his father."

Satan nodded.

"I want Rin to be the one to burn Shiro to ashes." He declared; a sinister smile upon his face.

He had no fatherly affections for the boy and if Lucifer's plans failed to prove successful, he would still be a backup vessel no doubt. But to hurt Shiro in the same way he had been, would be the sweetest revenge alongside Rin and himself burning humanity to ashes.

"If the other one hadn't been so human, I might've have taken him as well." Doesn't hurt to have spares after all "But I have a feeling he has known of the demon world long enough to resist me. Rin, however, was hurt by the lies of those humans and will be easily influenced."

"I noticed when he woke up, he was somewhat different towards you. It's not blaringly obvious but something has changed. He used to resist your touch or any help you offered. But he took your hand without even hesitating." Iblis said with a thoughtful look.

"Yes, he did, didn't he?" The corners of his mouth turned up in a sly smile. "I look forward to whatever changes this merge has brought on in my fledgling demon." His features darkened as he laughed.

To say that Rin had gotten carried away would've been an understatement as he laid there in the middle of the room surrounded by ash, slithers of blue flame slowly eating at the remains of whatever was left in the room. The feeling of being able to let go of his flames and let them eat away at whatever had been close by had put a wide smile on his face as he laughed to himself.
It felt like he was finally able to be himself and it made him happier than he'd felt in a long time.

When Satan had first mentioned merging with his demon half and 'sacrificing' his humanity he'd thought it the worst thing in the world, but now it had happened he wasn't so sure. He still wasn't sure if anything had really changed regarding his humanity, would he be able to notice a difference? He would have to wait until he got to return to Assiah before he would really know…

But for now, he was content with feeling awesome.

His only worry was Yukio, and what had transpired within his mind. Yukio had witnessed everything up until the climactic ending, the look of horror and fear on his face will not easily be erased from Rin's mind. Would this change things? He still cared for his brother that much he knew but he was also still angry at them as well.

Would Yukio treat him as an enemy if he eventually returned? Would he tell Father Fujimoto what happened? Most probably; would they try to kill him? He frowned at the thought.

He was brought out of his thoughts by a sudden pop followed by pink smoke. He waved his hands, coughing, trying to wave the smoke away. When the smoke finally cleared Rin noticed a strange looking demon dressed in a white suit with poufy-looking shorts, his outfit was decorated with pink and purple. On his head stood a white top hat; some more pink and purple decorated the rim. The demon appraised him greedily; Rin frowned. He looked around the burnt ashen room with a look of disgust.

"My, Father certainly has you set up nicely, hasn't he? You actually wanted to come back here?" He grimaced as he pulled out a tissue and held it over his nose and mouth.

"Who the hell are you?" Rin growled; drawing his flames to surround him. This demon felt powerful and Rin didn't like the sneer on his face.

"My my, such manners. I thought had Shiro raised you better than that." Rin froze at the mention of his adoptive father, the demon grinned mischievously. "My name is Mephisto Pheles, but you may have heard of me under another title from our siblings – they refer to me as Samael, The Demon King of Time. A pleasure to finally meet you, Rin Okumura." He paused whilst Rin took in the new information; eyes widening as the realisation hit him.

"Samael…you're Father Fujimoto's friend? The one who was to take me in when I was kicked out." Mephisto nodded. Rin stared at him before his stature relaxed slightly; an amused look drawing over his features "You look like some creepy perverted clown! Ha-ha" Rin laughed. If he was offended the demon didn't show it choosing the stare quizzically at the boy laughing in front of him.
"Why would Father Fujimoto want to send me to be taken care of by some creepy demon clown? Must've been desperate to get rid of me after all."

"So, why are you here? Did Father Fujimoto send you?"

"Alas, no. I am here to sate my own curiosity. I had been informed of Father's attempts to merge you with your demonic nature. I merely wanted to see the results of the said merge."

"Oh, I see. Yukio told you and now you're here to see if I'm a threat. Explains things I guess." Rin shrugged his shoulders as he stared the opposing demon down.

"So?" Mephisto tilted his head at the younger demon.

"Hm?" Rin crossed his arms behind his head and leant back against a nearby wall.

"Are you going to be a problem?" Mephisto asked; eyes focussing on Rin and narrowing slightly.

"I have no intention of being a problem." He frowned at the strangely dressed demon. It wasn't a lie; he had no idea what changes were taking place inside his head or body after that merge but he didn't have any desire to go on any killing spree's he knew that much.

Mephisto sat back with a smile, composure completely switched into a more light and airy mode.

"Very well then! I will take my leave."

"Wait, so you're not here to bust me out? Amaimon gave me the impression it was you that helped me before. You sent me this key, right?" Rin held up the key that had been gifted to him by Mephisto through Amaimon.

"You want to escape again?" Mephisto asked curiously; Rin paused to think about it for a moment. He'd only wanted to come back to stop himself from hurting his family. Once that problem was sorted, he'd hoped when the opportunity arose, he'd be able to go home again – but something was holding him back now.

"…No. Not now anyway. The pain might be gone but I still don't have enough control of my flames to be safe around them."

"Well, for now then Rin Okumura, I will depart." Rin nodded hesitantly, hoping he'd made the right decision. There was a pop and a puff of pink smoke as the demon disappeared as the word "Toodles!" echoed through the room.

As the smoke disappeared the door to Rin's room opened and stood in the doorway was Satan looking rather amused as he took in the state of Rin's room. Rin's tail wrapped itself tightly around his leg and he lowered his head slightly.

"I see you've been getting acquainted with your flames." Satan declared as he entered the room, disturbing some of the ash as he walked in barefoot. It was now Rin took in the demon's appearance fully.

Long white hair, messily falling to just below his shoulders; accompanied by a long white beard falling to a slightly shorter length. He wore a white robe, tied in the middle but from what he could tell nothing underneath. He wore no footwear like the other demon kings. His eyes returned to Satan's face before he realised something he'd forgotten, something he'd noticed when he first came here.

"Why do you look like Father Fujimoto?"

Satan was caught off-guard by the question but maybe it was a suitable time to fill Rin in on the details of his relationship with Shiro and in addition his mother. He smiled at the boy waving his hand, he sent his flames around the room – renewing all that Rin had destroyed with his own flames. He motioned towards a couch in the room, Rin hesitated but did as he was told and sat down; Satan sitting next to him.

"My true form is that of a Blue flame. I have no physical presence in Gehenna as you've seen when you attacked me in the throne room." Rin flinched at the reminder but nodded his response; Satan continued.

"I can take the form of anyone I have possessed in Assiah, albeit still not a physical body for me to venture to Assiah, it just gives me some sort of presence here among you and your siblings." As he explained he shifted his form to various bodies he'd possessed, however briefly, during the Blue Night.

"A lot of these humans died instantly upon my possession during what the humans are calling 'The Blue Night' but I will explain that later." He settled back to his original form. "The form I am right now is that of your father, or the body you were conceived with. His name if I recall was Goro, he was Shiro's brother." Rin shot a look at him in shock.

"Father Fujimoto had a brother?!"

"Quite a few apparently. This body, as well as Shiro and his other siblings, had been created and raised in a laboratory. At least, that was what I deemed from the vessel's memories. That was where I awoke for the first time, inside a giant tube of liquid."

"He was created in a lab…?" The more he stayed away from his family the more secrets and lies seemed to surface. Did Yukio know Father Fujimoto's past as well or was he just as in the dark? Somehow Rin doubted that since Yukio had known all the other shit that had been kept from him.

"Yes," Satan Nodded "But that is why this body resembles Shiro, it is his twin."

"So how does my mother fit in with all this. I can see how you'd know Father Fujimoto but how did you meet her?"

"Your mother was an exorcist. But I had known her since she was a child. Before I was who I am now. I would appear to her as a blue flame and she would engage me in certain activities. It was amusing. As she grew, I watched and followed."

"Iblis said she used to call you Rinka, and that I was named after you."

"Yes, before I gained knowledge about what I really was. After that I became Satan. That was when everything changed. I broke out of the lab and fled underground - for two years I hid. I returned when my body began to deteriorate and sought the help of those scientists who gave me an elixir. This worked for a time, but the exorcists tried to attack. Then Yuri returned to me, she stayed with me and then she was with child." He took note the wide eyes on Rin's face.

"We decided to leave the facility peacefully, my vessel would die and I would be returned to Gehenna. But Yuri would stay with me. Then as we escaped the exorcists surrounded us, they attacked Yuri and I and we were separated. For several months they kept us apart, experimenting on me in my weakened state. But my mind deteriorated with my body, in the end, there was only Yuri…"

Satan studied Rin for a moment before continuing, those human emotions still ripe within him – full of sorrow and pity over his mother and Satan's situation – he would need to drum those emotions out of him over time it seemed.

Continuing his story, he moved on to the Blue Night. Or at least his side of it.

"The next thing I knew I felt Yuri leaving me, dying. All that mattered was finding her. My vessel was finally lost and I was desperate for another body – trying to possess whoever I could. Which resulted in many deaths. This is what the humans call The Blue Night. It was also the night you had been born."

Rin looked up at that.

"I was not present during your birth, so I cannot give you any information on that. When I finally found Yuri…" He paused, he had to pick his words carefully here "…she was on the verge of death, holding both you and your brother in her arms. I tried to get to her but Shiro fought me off; I ended up weakened and returned to Gehenna. Yuri died soon after."

His true memories of the event drew more rage than sorrow from him. But he managed to hide it well enough to fool Rin. He didn't need to know of Shiro's love for Yuri or her love for Shiro. He didn't need to know how he possessed Shiro to be with Yuri, only to be rejected by her – that would just complicate his plans further.

"After Yuri's death, you were taken by Shiro and hidden. Raised by the priest to be used by the exorcists. As I told you when you arrived."

Rin sat very still, his tail shifting anxiously beside him. He wasn't sure what to make of all this. There was still a lot of unanswered questions and things Satan hadn't been present for. It wasn't a complete explanation of what had happened but it was at least something.

"Another thing…" Satan began "When I did finally reach Yuri, there had been some sort of a fight in the large chamber they kept her." Rin's eyes widened in shock, flashes of the memory that he couldn't recall were in the back of his mind.

"You mean…me?"

"Hm, it would seem you caused them quite some trouble. I imagine they tried to kill you and when that failed the only other option was to seal your demon heart."

"So, the only reason I'm alive is because they couldn't kill me?"

"They probably tried to kill your brother as well." The memory of a woman screaming for her baby returned fresh in Rin's mind the feeling of anger that came with it when he realised, they had been trying to kill a baby Yukio. He growled loudly, flames leaking from his body as he shook with that forgotten rage.

Before he had a chance to react further his head was pulled into the older demon's chest, clawed fingers raked through his pale blue hair. Rin's rage dissipated with the shock and he froze. But as Satan stroked his hands through Rin's hair he relaxed into the hold. Satan grinned darkly above him.

"You belong with me…"

A single tear rolled down Rin's face as he nodded.

Okay so before anything else, I am sorry for my updates with this being few and far between. I do not have a lot of time to myself so what time I do have is spread out over various hobbies and other commitments.
To explain things a bit further I have 2 kids, one of which is 1 year old and with me all day, so I generally can't use my laptop whilst she's around as she likes to play with it...it's fragile! I also work evenings, I don't get home and comfortable till around 10pm so I end up staying up late just to get that 'me' time.

I'm basically saying this so if an update isn't as fast as people would like it doesn't mean I'm not working on it :D! I don't have a set update schedule and will update as and when I can. This chapter was quite difficult as I wasn't overly inspired to begin with (and that last manga chapter killed me T_T). So please bear with me - I do have some future chapters already planned/written out but the bits in-between are a pain.

Thank you again for all the follows/faves and reviews, they really keep me motivated - but please don't worry about how long its been since the last update. I keep track - don't worry! (Unless I've been dead a year then feel free to poke). I am on various social media so if you would like a status update please contact me there or in PMs!
