I'm sorry I'm sorry I'm sorry I'm sorry I'm sorry I'm sorry I'm sorry *bowing* I know I haven't published in forever when I said I was going to publish a new chapter so I'm sorry guys please forgive me T-T.

I am sleeping peacefully when I am startled awake. When I hear Amaimon shout in my head. "Wake up Rin! You're late for training!"

Groaning I yawn tiredly rubbing the sleep from my eyes. "Alright I'll be right there."

I pause when I feel something wrapped tightly around my waist. As my hand is touching something warm. Blinking I look around to see that Bon is asleep in my bed. His arms wrapped securely around my waist. While my hand had some how found its way up his shirt. I blush deeply as I remember everything that happen yesterday. 

Very carefully I manage to wiggle my way out of his hold without waking him. Heading to my closet I quickly change into my training clothes.

I am about to leave when I stop at the door. Glancing back at Bon I decided to leave him a note. Heading over to my desk I pull out a pen and pad. Quickly I write down where I went picking up the pad I set it down on the nightstand where he can see it. Leaning down over his sleeping form I smile softly as I kiss him before leaving. 

Heading down the hall my torches light up as I pass. Making sure to keep them dimmed as it is still very early so everyone is still asleep in bed. Getting to the training room I light it up brightly, so we can all see. "About time you got here Rin. We have been waiting forever."

Baring my teeth I let out a low growl before sticking my tongue out at Iblis. That's when I notice that Samuel is missing. "Azazel where is Samuel?"

"He is in Assiah again."

"Either way even if he was in Gehenna you know he still wouldn't show."

I shrug my shoulders as Lucifer reminds me that Samuel hates training. With that we all pair off Azazel refusing to let me train with Iblis, Astaroth, or Amaimon. As we would end up destroying the castle again, so I pair up with Azazel. While Astaroth pairs up with Lucifer. Iblis going with Egyn and Beelzebub being with Amaimon. All of us being matched with someone who can counter the other's powers. After figuring out who our sparing partner we head onto the mats. First we start off with hand to hand combat with no powers. 

We do this for two hours before we start to use our powers. Azazel had taken me down a few times with no powers. But now that we are using our powers we are easily matched. As my powers are a lot stronger than Azazel's. Though Azazel is much older than me making him more skilled and knowledgeable. His centuries of experience balancing out my raw power.

My tail thrashes excitedly behind me, but I quickly pull it in close. As a demon's tail is their weakest spot as my father and brothers always keep their tail hidden except for Astaroth. As he finds it as uncomfortable and stiff as I do.

Lunging at Azazel I tackle him taking him to the ground. Though he quickly throws me off him. I land on my feet my claws digging deep into the mat as I go skidding across the floor. Letting out a growl my tail continues to thrash in excitement. A smirk dancing across my face as I notice that Azazel's braid is messed up. Frowning when he notices he sighs pushing the now loose strands of hair out of my face.  "Alright then pup lets get serious." 

Reaching into his chest he pulls out a silvery white staff. My other brothers stop sparring when they notice Azazel pull out his staff. Standing up straight I dust myself off as the real fun is about to begin. Reaching into the center of my chest I pull the Koma sword out. I remove it from the sheath tossing it Iblis who catches the sheath with ease. 

My flames covering my sword as I take a fighting stance. The two of us circling each other waiting for the other to attack. Which is when we both make the first move attacking at the same time.

Yukio's P.O.V.

I am startled out of my sleep when I hear a voice in my head shout. "Wake up Rin! You're late for training!"

After a few moments I then hear Rin's voice in my head next. "Alright I'll be right there."

Knowing that I would not be able to fall back asleep I decide to get up. Walking over to the closet I decide to go through my options. A lot of the clothes being dark colors I grab a dark grey button up shirt with slacks and shoes that match. Heading to the bathroom I take a quick shower before I get dressed. Once dressed I decide to leave my room and explore castle. 

As soon as I step out of my room and into the hallway the dimly lit torches flare to life. Walking around the endless hallways I end up in Rin's throne room.  Reminding me of what happen yesterday in this room. All my life had been there every time Rin had become angry or gotten into a fight. But I had never seen him that violent and aggressive. 

As I could see the intentions that Rin had for the demon. He actually might have if the demon kings hadn't separated them in time. But even then with all seven of them holding him back he broke their hold. I shudder at the thought of what my brother has become. This is not the life that I had wished for him. 

But it still feels wrong every time he calls any of the demon kings his brother or when he calls Satan father. Glancing at Rin's throne I let out a heavy sigh. Before I decide to continue looking around.

After wandering aimlessly around the halls for an hour I end up in the dining room. Where I find all the exorcists at the table eating. Sitting down at the table I notice that Rin isn't there. "Where is Rin?"

"Training."

I glance at Bon and frown slightly before I start to eat. After we all finish the food on our plate we go looking for Rin. Eventually we find him in what I am guessing is the training room. Which is also where we find all the demon kings sparing in pairs. My eyes automatically lock onto Rin who is sparring with the long white haired demon named Azazel.

Watching them fight I notice a major difference in Rin's fighting style. Before it was chaotic and random, but now it is precise and controlled. As he uses his powers as if they are apart of him, but I also notice the more animalistic style in his fighting too. Rin tackles Azazel the two hitting the ground hard.

Though Rin is quickly thrown across the room by the demon king of spirts. Rin lands on all fours his nails digging deep into the mat as he skids to a stop. His tail thrashing around like a wild animal as he growls lowly baring his fangs. It makes me wince slightly as Rin never use to growl or show his fangs. This showing me how much like a demon Rin has really become.

A smirk comes across Rin's face as he stays on all fours like a preparator ready to attack. With a frown Azazel sighs as he brushes the hair out of his face. "Alright then pup lets get serious."

Azazel reaches into his chest and pulls out a silvery white staff. The other demon kings seem to notice this as they all stop their sparing. Finally standing up right Rin dusts himself before readjusting his clothing. Before he also reaches into his chest pulling out the Koma sword. Freeing it from its sheath he tosses the sheath to the Demon King  of fire Iblis. The Demon King catching it with ease. 

Then what happens next surprises me Rin's sword becomes covered in flames. They both take a fighting stance circling each other. Until they both attacking each other at the same time. Their weapons clash as they dodge each other's attack. Rin's movements seem faster as his blows seem to get stronger with each blow. The other Demon Kings stepping off the mat. Giving Rin and Azazel the room they need.

The fight is long, but eventually Rin knocks Azazel to the ground. Rin holding his still flaming sword to the King of Spirits' throat. "I believe he finally beat you Azazel."

All of us except for the Demon Kings and Rin jump in surprise. As we hear a voice behind us. Turning around we move out the way as a tall demon walks by us. His hair a raven black and long hair that goes down to his shoulder blades like Azazel's. Though it is his eyes that catch me off guard. His eyes looking Identical to Rin's. 

He is dressed in all black with hints of blue. His cape flows behind him as he walks revealing the black sword with a blue undertone hanging from his left hip. Iblis tosses Rin the sheath to his sword. Returning the sword to its sheath he attaches it to his left hip. Before he helps Azazel up to his feet. "Yes he is improving rapidly everyday."

"That is good I very proud of you Rin."

The demon smiles at Rin showing his fangs. Which makes a large grin appear on Rin's face. That is until the unknown demon ruffles Rin's hair. Rin growls quickly pulling away from the demon's touch. Rin grumbles at the demon as he fixes his hair. "Father you messed up my hair."

The Deon Kings and the demon laugh at Rin. While my heart stops when I realize that the demon talking to Rin is Satan. The monster who killed our father and is the reason Rin's demon side was awaken. When they stop laughing I glare at Satan as he places a hand on Rin's shoulder. "But in all seriousness Rin. You will make an amazing King when you take over as King of Gehenna."

As soon as I hear that I kind of snap. "When you what?!"

Rin jumps flinching slightly making me feel a bit guilty. Which is when Satan turns his attention toward me. "Ah Yukio my youngest son. I haven't seen you in centuries look how you  have grown. It is good to have you home at last and to answer your question Rin is my successor. Heir to the throne of Gehenna as he has my flames."

With each word I become angrier and angrier till I explode. "You are not my father! You murdered him in cold blood! My home is Assiah not Gehenna! Rin isn't a demon or Heir to Gehenna's throne he is human! You are the reason he is like this!"

My graze then locks onto Rin. "And you! How can you call that monster father?! When he killed Shiro who was our real father!" 

I notice Rin flinch as he refuses to meet my eyes. But right now I was to angry to care. Satan places a comforting hand on Rin's back and I hear Satan's voice in my head. "Do not be upset with him Rin. He does not know the truth."

"Don't try and have a secret conversation about me! Especially when I am standing right in front of you!"

Satan looks at me slightly surprised that I was able to hear their secret conversation. "Interesting. Well then if you would let us explain. Then you would be able to understand."

"Like I would believe anything you have to say! You are a no good demon! A monster!"

Next thing I know I am being slammed up against the wall. Groaning in pain I grit my teeth as everything is spinning. When my vision normalizes I am surprised as I expected to see Satan holding me against the wall, but instead I see that it is Rin. Rage burning in his eyes as his flaming blue wings flare out behind him. "If you hate demons, so much then why don't I take you back to Assiah! So you can go back to the Blue Cross Academy! The very people that tried to kill me! Where you can go back to killing demons like me! And don't you dare speak to my father like that when you don't even know the truth! He offered me a life of Assiah! But I choose to become a full demon! I choose to become the Demon King of Shadows! I agreed to become his successor and heir to the throne of Gehenna! So if you want to see a monster, so badly how about I show you one!"

Rin's wings grow as he bares his fangs at me. "Rin that's enough."

Satan doesn't shout as his voice is soft and cool. Putting his wings away he growls when he lets me go. Before walking back over to Satan Rin glaring at me with a rage that I have never seen in him. "Iblis take your brother to go calm down."

"Yes father."

Placing a hand on Rin they both vanish as do the other Demon Kings. Leaving us alone with Satan who walks over to us. "Please do not take your anger out on your brother."

Satan actually looks sad as he says this. "If you wish to return to Assiah any of you. All you have to do is ask."

With that he vanishes, but then next thing I know I am punched in the face by Bon. "Rin may be a Demon King now, but he is still your brother! He deserves better than to be called a no good demon and a monster by his own brother!"

Without another word Bon storms off. Leaving me in shock on the floor with a bloody nose.

Bon's P.O.V. 

Satan looks at Yukio with surprise. We all are as Yukio is always, so cool headed its shocking to see him blowup like this. 

"Interesting. Well then if you would let us explain. Then you would be able to understand."

"Like I would believe anything you have to say! You are a no good demon! A monster!"

I glance at Rin seeing the anger on his face. When all of a sudden Rin lunges at Yukio. Slamming him into the wall as his flaming wings come out. Yukio letting out a pained grunt. When he comes out of his daze he looks surprised to see Rin is the one holding against the wall. His tail whipping around like crazy with anger. "If you hate demons, so much then why don't I take you back to Assiah! So you can go back to the Blue Cross Academy! The very people that tried to kill me! Where you can go back to killing demons like me! And don't you dare speak to my father like that when you don't even know the truth! He offered me a life of Assiah! But I choose to become a full demon! I choose to become the Demon King of Shadows! I agreed to become his successor and heir to the throne of Gehenna! So if you want to see a monster, so badly how about I show you one!"

Rin bares his fangs at Yukio his wings growing bigger as the room gets darker.  "Rin that's enough."

Satan's voice being calm and soft spoken as he snaps Rin out of his rage. The room going back to normal as Rin's wings disappear. As he lets go of Yukio and walks back over to Satan. While glaring at Yukio with, so much anger that I've never seen in him. "Iblis take your brother to go calm down."

"Yes father."

Walking over to Rin Iblis places a hand on his back. When he does they both vanish as do the other Demon Kings. Which leaves us alone in the room with Satan. He walks over to Yukio with a sad look on his face. "Please do not take your anger out on your brother. If you wish to return to Assiah any of you. All you have to do is ask."

With that he vanishes into thin air. Which is when I let out my anger at Yukio by punching him in the nose. Knocking him down to the ground as his nose starts to bleed. "Rin may be a Demon King now, but he is still your brother! He deserves better than to be called a no good demon and a monster by his own brother!"

Still very angry I turn around and leave before I end up punching Yukio again. Heading to Rin's room I still on his bed and wait for him. After an hour the door opens and Rin steps in. As soon as he closes the door I rush to his side and pull him into my arms. He tenses up at first before relaxing into my arms. I kiss the top of his head as I rub soothing circles on his back. Burying his face into my neck he hugs me tightly. "You don't think that I am a monster do you?"

I pull Rin back from me which automatically makes him look away. Gently I take his chin into my hand to try and make him look at me. But his eyes still refuse to meet mine. "Rin look at me... Please."

His deep blue eyes finally looking up at me. "You are not a monster and never will be. You could destroy both worlds and I still wouldn't see you as a monster. Maybe just a bit cranky or hungry."

Rin's smile returns as he laughs. Before he pulls my head down, so he can kiss me. When we pull away I rest my forehead against Rin's. "Bon?"

"Yes Rinny?"

I smirk at the blush I caused. "Can I show you something?"

"Of course you can."

"Okay then close your eyes."

chuckling I steal a quick kiss before I close my eyes. Rin holds my hand as I feel a sudden tug. "Okay you can open your eyes."

I open my eyes and find myself no longer in Rin's room. Instead we are in the middle of a blue rose bush maze. In the large clearing is an old massive oak like tree. Its trunk and branches being as black as the Gehenna sky. While the leaves are as blue as Rin's flames. Hanging from the lowest branch is a bench swing. Rin sits down on it, so I join him. "This is my safe place. Where I can relax and get away. No one knows about this place except for my father and brothers. Only family can get enter and find their way through the maze."

Rin smiles happily as he leans into me. "Then how did I get through."

I wrap my arm around him pulling him close. As he blushes deeply looks up at me shyly. "That's because you are my mate. I mean if you want to be my mate."

Chuckling I kiss his lips deeply. "Of course I want to be you mate Rin."

Smiling Rin kisses me back I deepen the kiss not wanting it to stop. I hear Rin snap his fingers making me pull away slightly. When I notice that we are no longer on the bench swing. But now we are laying on a blanket under the tree. "I thought this might be more comfortable."

Smirking I start kissing him again. before I flip up so he is pinned to the ground. While I am the one on top just like yesterday.
