Finally! This took me forever to type! It's also the middle of the night... I want to sleep... Anyway, I hope you enjoy it! It's the first time I've written a second chapter for anything!

"Blah" Speech

'Blah' Thought

Disclaimer: I don't own Ao no Exorcist. Kazue Kato-dono does, and that's probably for the better.

"We must learn to live together as brothers or perish together as fools."

Dr. Martin Luther King Jr.

Rin stood out in the rain in front his father's, no, Fujimoto's grave, Kurikara on his back. He stared blankly at the final resting place of the man who had raised him as a human all these years. Rin dryly chuckled at that. Who would have guesses all those years to be based on a lie? What was he going to do now? He had failed Yuri. Yukio was moving away, and Rin was going to be left behind. How could he protect Yukio now?

He sighed. 'I guess I'll have to figure something out.' And he remembered.

Flashback

"What are you doing Jiji?" Rin questioned Fujimoto, still trying to process what exactly was going on. First, there are demons in this world, and several are trying to attack him now. Second, he himself is a demon, and not just any demon, but the son of Satan himself!

His question went unanswered as Fujimoto placed a phone in his hand. "Take this phone. There's only one number on it. We'll hold out until morning, then you call him. He'll take hold of you from there."

Present Time

He dug the cell phone out of his pocket. If he's going to help Yukio, then maybe this contact would be of use. He pressed the send button, and held it to his ear. He heard the dial tone for a while, but turned when he heard ringing close by. His eyes widened. 'When did those men get here?! I never even heard them approach!' As he found himself surrounded by at least 12 men, all of them wearing black trench coats, and wearing masks obscuring the lower half of their face.

Finally he noticed who was holding the ringing phone. A rather tall man, dressed in a jester outfit, with a very unique umbrella, but Satan recognized him, none other than his rogue son Samael, Demon King of Time.

"It's a pleasure to meet you, Rin Okumura. Allow me to offer my sincere apologies. I was a friend of Fujimoto's, but we are the Knights of the True Cross"

'So they're exorcists, hm…' Satan thought.

"Unfortunately you only have two choices. As the son of Satan we must exterminate you, so we either kill you, or you kill us, or you could kill yourself, so I guess that makes three…So which is it. my young acquaintance?" Mephisto continued.

Rin's eyes narrowed, 'So he isn't aware I'm Satan. He thinks I'm my own son. That's kind of weird. Although I could easily kill all of them, but it would make my promise to Yuri much harder. And as a demon, I keep my promises. However, demons currently think me dead or missing, so I doubt they would listen to me now, meaning they could put Yukio in serious harm, so that leaves option four…' He opened his mouth to speak, something he never believed he would say, "Let me become an exorcist!"

Mephisto's eyes literally looked like dinner plate, then he burst into laughter, "You, the son of Satan, an exorcist? That's the most ridiculous thing I've ever heard!"

Satan was silently fuming inside, 'The funniest thing ever is your choice of clothing! I swear he gets it from his mother! Well, whichever demon she was again… Was it the one in Gehenna's suburbs? No, that was Amaimon's. You'd think after eight kids I'd know them better…' Then he remembered, 'Oy! You're my son as well, and you're one of the head exorcists! I'll kill him for that slight later, but he's more useful to me alive than dead.' Satan grumbled in his mind.

Mephisto spoke, interrupting Rin's thoughts, "Ha! You must be insane! Why would you want to be an exorcist?"

Rin spoke so silently Mephisto almost didn't hear it, "To keep my promise! To protect Yukio! And I don't care who it is, if they get in my way, I'll kick their ass!"

Mephisto simply gave his trademark smile, "The son of Satan wishes to be an exorcist, huh? Interesting! I approve!"

"Sir Pheles!" One of the exorcists tried to put his own two yen in, but Mephisto interrupted him.

"You have chosen the difficult path. I can't wait to see how this turns out!"

Rin simply smirked himself, something Mephisto felt a slight chill because of its similarity to his father's smirk. He spoke, "I'm not human, but I will be an exorcist! No matter what!" Inside however, Satan thought, 'I've stood against the Divine Himself, I've devoted my life to the ruin of humanity, and I've led to the legions of Gehenna itself. This is nothing! But Samael thinks that he maniplulate me! Let's see what happens, when the manipulated becomes the manipulator!'

The next day, Rin was waiting outside the old Monastery as he waited for Mephisto to pick him up. He had the duffel bag that Fujimoto had packed for him before the untimely events of last night. It didn't hurt that living in a monastery, he actually had very few things, as it's not exactly a life of luxury. Satan had to laugh at that irony.

"Nii-san!" Rin turned back to the voice of his little "brother."

"Oh? Coming to say goodbye Yukio? I'm touched!" Rin replied, a smirk on his face. Although it did die a little when he saw Yukio was confused.

"Who said anything about goodbye?"

HONK!

Rin jumped at the sudden noise as a hideously pink Limo drove up seemingly from thin air. Rin could only blink as Mephisto emerged from the car. 'I swear he's adopted! There's no way this… thing is related to me!'

"Guten Tag! Now, my dear Okumura siblings! Shall we away?" Mephisto flamboyantly exclaimed.

Yukio bowed in respect, "Thank you Mr. Faust for your generosity. I'm grateful that you could make provisions for Rin as well."

Rin turned to Mephisto, "What provisions? And Faust? I thought your name was umpmh—" The rest of his sentence was smothered when Mephisto quickly grabbed him away.

"Faust is my business name. Now there's no need to mix the two worlds, is there?" He whispered to Rin. "Now then! Away we go!"

"Wagh!" Rin yelled as Mephisto threw him into the limo. Yukio smiled, and picked up Rin's duffel bag and followed them into the limo, which took off at probably less than legal speeds.

Rin was currently on the ground, swirls in his eyes at the hectic driving. "Who the hell is that driver, and why the hell is he even getting away with this?!" He shouted!

"He's my driver of course!"

"Well, no shit you stupid clown!"

"Nonsense! Besides, we're almost here!"

"Here? Where the hell is here?!"

"My school, True Cross Academy!"

Rin worked up the courage to look out the window, and his jaw promptly fell open. "That's no school!" He exclaimed, and he was probably right. True Cross Academy dominated the skyline, a vast monolithic collection of buildings set upon a giant hill. It looked more like a castle than a school! But he caught something that didn't register with what he knew.

"Wait, what do you mean your school!"

"Nii-san, you didn't know? Mr. Faust is the Headmaster of True Cross Academy."

"What?!" How did Samael set all this up without him knowing! He must be getting rusty in his old age…

The limo from hell quickly pulled to a stop in front, at least, what he thought was the front, and Rin promptly flew forward into the dividing window between the passengers and the driver.

"Tsk tsk, my dear Okumura-kun! Always remember your seat belt!"

"Thank you again for your generosity, Mr. Faust. I need to start preparing for classes, so I need to leave quickly." Yukio stepped out and bowed respectfully. "Please watch after Rin for me. He's always getting into something."

"Hey!" Rin jumped up and banged his head on the ceiling, "Damn it! Stupid car!"

"It's a limo."

"No one asked you stupid clown!"

"See you in a little bit Nii-san!" Yukio began walking off.

"Hey, where are you go-wagh!" Rin jumped out, only for Mephisto to drag him back in. "Will you stop that?!"

"Nope!" Mephisto threw a bundle in his face, smiling all the way.

"I really hate you…" Rin grumbled while he unfolded the bundle to see a… school uniform? "What's the deal with this!"

"It should be simple my dear Okumura-kun! You're going to school!"

Rin's eyes widened. "What?!" He shrieked for the umpteenth time since meeting Mephisto.

"I've enrolled you in the classes here. Considering you couldn't realize that simple fact you might need them."

Rin grumbled, and began getting changed into the school uniform. He began pondering all the various ways that he could torture Mephisto should he even get the chance. Satan cackled in his mind. Oh the fun he'd have! He continued cackling for a while until he realized something. 'Wait, this is Yukio's school! I can continue watching over Yukio! Samael, this almost makes up for the torture you've been giving me! But…' Satan looked at Mephisto, grinning all the while. Once again, Mephisto felt a chill at how much Rin looked like Satan. It was almost disturbing. Satan continued his thought, 'Not quite.' All around True Cross Town, people felt a chill go through them, just from the mental laughter of the God of Demons.

Satan was happy, no, he was ecstatic, rapturous, joyful, and he didn't even know what half of those meant! His plan had worked far better than he expected! Not only would he be getting more training to take care of Yukio, Samael was also the head of True Cross Academy! Thank goodness Fujimoto taught him how to tie a tie though… He had nearly strangled himself with that death trap!

He paused outside as he reflected on what he learned. Yukio was a freaking genius! He was the top new student! And Satan could tell, especially from what he could sense from the other students: the pride emanating from all of them. Despite their arrogance, they were all very capable students, but grew boastful from it. He licked his lips. Their sins made a delicious meal though! Now what to do next…

"Thank you for waiting, my dear Rin-kun!" He turned to face Samael, who leapt down from his pole. "Now, you will begin learning to be an exorcist at the Cram School, starting as a page, starting today. However, you must keep your identity secret! Under no circumstances must you reveal your flames to the others! To that extent, Einz, Zwei, Drei!" And he snapped his fingers.

The poof of smoke had Rin coughing, and when it cleared he saw Mephisto was… a terrier? 'Really Samael, a dog? And a tiny one at that! I think I've let you roam freely around this world for too long…'

"I'm afraid how this will work out, so I will observe the first day. Oh, and here." Rin saw he was holding a key in his mouth, so he took it. "Put that key in any doorway." Satan was really confused by it, but he did so anyway. When he walked through he was quite surprised. 'Okay, I know the doorway could NOT lead to a place this big!' He looked at the key in amazement. He never would have thought humans could have such things, then again, he could create Gehenna Gate…

He headed to the cram school room, and was surprised to find it rather empty. There was only about seven people in the room. He idly noticed two girls, probably friends, a boy playing with a puppet, 'Creepy,' a short bald-headed boy, next to two other boys with… interesting hair styles, one with pink hair, the other with a blonde streak, 'Is that what humans think is fashionable nowadays?' and a person wearing a hoodie in the back, 'Isn't that hot?'

"As you might notice, we don't get too many exorcists. This is even a lot for us. Oh, quiet down, your teacher is coming in" Mephisto whispered, so that only Rin's demon hearing could pick it up.

Rin nearly choked on his spit, when Yukio walked in, bearing enough ammunition to make a Marine jealous. What the Gehenna was going on?! This wasn't in his plan!

"Hello class, despite my young age, I'm your new demon pharmaceuticals teacher. My name is Yukio Okumura. Now, who here has not gotten a temptaint?" Several people raised their hands.

"A temptaint is needed to for a regular person to be able to see a demon. All exorcists must go through this ritual to be able to see demons. Of course you won't have to!~" Mephisto-terrier explained. Although Rin already knew this.

"Three huh? Alright, now I'm going to prepare a mixture using animal blood and milk to draw some hobgoblins out."

As Yukio was preparing the mixture, Satan was troubled. This complicates things. What was he going to do now? He needs to keep Yukio safe, but if Yukio should figure out who he is… Before he was unsealed, he probably would have just burst out, but now, what should he do? 'Ah, to Hell with it!' He stood up.

"Yukio, what's the meaning of this!" He walked up to the teacher's desk.

"Whatever do you mean Okumura-san?"

Satan was now fuming. He hated quite a few things: bright lights, holy water, reading, waking up before the alarm clock, social media (that's a loooong story…), but he really hates being lied to (ironically), and not having his questions answered. Normally whoever did both of these would be a molten pile of goo on the ground, but he couldn't do that to Yukio. "You know what I mean!"

"Please sit down, Okumura-san." Yukio nonchalantly replied as he prepared his concoction. "We're in the middle of class!"

"Knock it off!" The elder, and perhaps eldest being in the room, Okumura furiously demanded, wanting, no, needing to know why he was here.

Yukio sighed, as he pushed his glasses up his nose, "As I mentioned earlier, I became an exorcist two years ago, but I began training at age seven." Yukio began, speaking quietly enough that only Rin could hear it. "I was infected with temptaint by my twin brother at birth. Thus, I've seen demons since before I could crawl." Rin's eyes were wide, as he slowly processed what he had heard. "I've known the whole time. The only one who didn't know was you." Yukio concluded. "Now return to your seat."

Rin's arms fell to his side limp, his eyes shadowed by his hair. He had... failed? 'I promised Yuri that I would keep him safe... in the end, I only brought him misery, and by my own carelessness!' If there was anything Satan hated, it was failure. He had experienced that far too many times in his eternally damned life, and if there was one thing that brought him hope, it was keeping Yuri's last wish, but now... not only he had failed... Rin's hands clenched tightly, as his rage grew. Not only had he failed, but his precious adopted brother that he had sworn to protect, he had LIED to him?!

Rin's hand shot out faster than even Yukio's trained eyes could spot as he furiously grabbed his arm, much to the bewilderment of the class. "If you knew, why didn't you tell me?!" Unfortunately, he knocked the vial out of Yukio's hand he was holding, and it shattered.

Rin grabbed his nose, as his enhanced demon senses picked up the incredibly vile smell. Honestly, he never knew why Hobgoblins loved that stuff! "That stinks!" He muttered out, before a sudden explosion from the ceiling made him turn behind.

"Demons!" One of the students shouted.

"What?! Where?!" Another one, who obviously hadn't received a temptaint yet, screamed, looking for the invisible creature.

"There!"

Rin could see the hobgoblins rushing towards the students, driven wild by the blood. He honestly didn't care what happened to the students, but he did care when the demons suddenly exploded, together with the all too familiar sound of a gun. He rapidly turned to face Yukio, as he saw him, face completely serious, as he viciously murdered Satan's kin. "Everyone please evacuate the classroom!" Yukio ordered as he continued exorcising the infestation, waiting for a lull in the waves.

He quickly opened the door, "They're small, but they're a lot of them... the blood also has caused them to become more aggressive. Please wait outside while I get rid of them." He commanded, as he ushered everyone out, until he saw only his elder brother was left.

"You too Rin" When Yukio noticed everyone else had cleared out, but Rin simply kicked the door shut.

"We're not done talking!" Rin shouted. "And it wasn't your fault, it was mine!" Yukio would never understand the double-meaning behind the apology, not for a long time.

Yukio sighed, as a hobgoblin rushed towards him from behind, and faster than Rin could acknowledge was possible, he whipped out his gun and shot it. But Rin could see Yukio was quickly getting overwhelmed, and he prepared to help, until Yukio pulled out a second gun, and started freaking dual-wielding!

Rin's face was just blank, as he tried to register this, 'What?' Was his only thought.

Not only that, when his ammo ran out in one gun, Yukio smoothly ejected the empty cartridge from the gun, and expertly reloaded it using a special ammo carrier on his belt. "There's nothing else to say. I'm busy now, so save your whining for later." Yukio bluntly stated to Rin.

Satan might have been fuming, but now he was pissed! How could he have gone so long without learning any of this! Hobgoblins rushed towards him, swarming around him, but he burst into flames and annihilated them. "Listen to me! We hardly talked since To- Father Fujimoto died. If you knew, what did you think of me, all this time?!"

"That you're a threat. That you're dangerous. If it weren't for you, Tou-san would still be alive! He never would have lost to any demon, even a demon king! You were always his weakness! Because he had to protect you, he died!"

Satan narrowed his eyes. He didn't care anything about that man! Because of him, he was sealed away for 15 years! At the same time though, Yukio cared, and it was his fault that Fujimoto died.

Flashback

Fujimoto placed a phone in his hand. "Take this phone. There's only one number on it. We'll hold out until morning, then you call him. He'll take hold of you from there."

Now, he walked over to the altar and moved it back. He quickly walked down, and Rin followed. Fujimoto pulled out a key and opened the cabinet inside. He pulled out a blue katana, "This is the Kurikara. It has your demon powers sealed inside. Never draw it, or your life as a human will end." A giant crash emerged from upstairs, and Fujimoto rushed upstairs as he hurriedly placed the sword into Rin's hands.

Rin rushed upstairs, still trying to process what was going on, only to see Fujimoto dealing with the demon from earlier. What was he called again? Assrot or something like that? He could only gape as Fujimoto proceeded to Judo throw the demon against the wall. The demon proceeded to transform into a beastly form, but Fujimoto merely pulled a shotgun out and shot the demon point-blank.

Fujimoto prepared to recite Scripture to exorcist it, but he was interrupted by Rin grabbing his arm. "What is the meaning of this Jiji? Why are you getting rid of me?"

"I don't have time for this Rin! You need to get ready to get out of here! Now— Hngh!" Fujimoto felt searing pain in his chest. He looked down to see a claw protruding from his chest. "Damn it. I was too… slow…" He collapsed limply as Astaroth withdrew his claw, while Rin could only look on in horror.

Present Time

"Why did you become an exorcist Nii-san? Why did you join the Order? Atonement? Revenge? Regardless of why you joined, it's too late now. You should just turn yourself into the order, or... maybe you should just die."

Rin tried to register that, as the child of the only woman he ever loved pointed his gun at him. "Wh-what did you just say?" He asked, almost unbelievably.

Yukio continued his conversation, as he continued shooting the hobgoblins at the same time. Yukio unleashed his frustrations, "Tou-san protected you! He was our strongest exorcist! They even say he was the only one to be able to resist possession by Satan! But, if there was one weakness, it was you, Rin!" Yukio finally yelled, as he pointed his gun directly at Rin. "You killed Tou-san!" All his attention now focused on Rin, as the largest of all the hobgoblins appeared behind him, his backside completely exposed.

Rin looked on, as he slowly began to flame, "You can call me names, you can fight me, you can tell me to die, but never, and I mean, never point a gun at me, Yukio! Do you understand!" Rin yelled, while raising his right hand, and formed a ball of blue flame, and he crushed it, sending tendrils of flame heading in Yukio's direction.

He braced himself, expecting to burn alive, but he heard growls coming from behind, and turned around, watching the fire consume some of the largest goblins he had seen. His eyes widened. Rin had saved him!

"We're family!" Rin yelled, as the hobgoblins exploded in a burst of blue flame, honestly one of the most beautiful things Yukio has ever seen. Rin just walked out, still seething. "Don't mess with me. I would never hurt someone I promised to protect." Rin continued walking, opened the door and walked out, leaving Yukio to wonder what just happened, and Mephisto-terrier who had been watching the entire scene play out, to gape in awe.

"Let's see... Room 602... Room 602..." Rin muttered, as he wandered the old and abandoned dorm. "Where the hell is everyone?" He said, albeit to no one in particular. He finally came to the sign that said 602. "Is this it?" He groaned, after a couple hours of searching. Honestly, these human numberings sometimes made no sense! He grasped for the light switch. "Where is everyone?" He asked, as he flicked on the light to reveal... Yukio?!

Yukio just smiled from the desk he was sitting at, his yet to be unpacked boxes close by. "Hi... surprised?" Yukio cheerfully asked.

"I... uh... what, why, when..." Rin stammered out, not quite sure how to react, given today's whole fiasco.

"First years are usually four to a room, but I got us an exception." Yukio cheerfully smiled.

"Wait, have you just been waiting in the dark for me to come?" Rin asked, but again Yukio smiled.

"You're dangerous, so someone needs to keep an eye on you! It was my idea!" Yukio cheerfully explained.

"Wait, so is this a prison?!" Rin shouted.

"Yeah, and I'm the warden!" Yukio smiled, although he was unprepared for Rin to start sulking in the background.

'I escaped one prison, only to end up in another one!' Satan silently sobbed.

Later, after Yukio dealt with Rin's sudden inexplicable mental break-down, and getting him to sleep, he went upstairs to handle a private phone call, namely one from a certain polka-dotted demon, regarding today. "Well, you were a little stiff, but you did remarkable well!" Mephisto said.

"I mean about HIM." Yukio pushed.

"Hm... for being so freshly awakened, he was capable of handling his power extraordinarily well. I honestly was quite surprised. If he progresses the same way, he will be a powerful weapon for the Knights of the True Cross."

"Then we must keep an eye on him then." Yukio concluded.

"I don't want the upper ranks to learn about him just yet... It's only a matter of time, but we absolutely cannot lose him, even if he is somewhat stubborn and thick-headed."

Yukio pushed his glasses on his face. "His recklessness is only going to get him killed though. Despite our disagreements, he's still right. We're brothers. I made a promise to Tou-san, and I will keep it. I will protect Rin."

"καὶ εἶπεν Καιν πρὸς Αβελ τὸν ἀδελφὸν αὐτοῦ διέλθωμεν εἰς τὸ πεδίον καὶ ἐγένετο ἐν τῷ εἶναι αὐτοὺς ἐν τῷ πεδίῳ καὶ ἀνέστη Καιν ἐπὶ Αβελ τὸν ἀδελφὸν αὐτοῦ καὶ ἀπέκτεινεν αὐτόν. καὶ εἶπεν ὁ θεὸς πρὸς Καιν ποῦ ἐστιν Αβελ ὁ ἀδελφός σου ὁ δὲ εἶπεν οὐ γινώσκω μὴ φύλαξ τοῦ ἀδελφοῦ μού εἰμι ἐγώ ."

"Et ait Dominus ad Cain : Ubi est Abel frater tuus? Qui respondit : Nescio : num custos fratris mei sum ego? 10 Dixitque ad eum : Quid fecisti? vox sanguinis fratris tui clamat ad me de terra. "

"Cain said to his brother Abel, "Let us go out in the field." When they were in the field, Cain attacked his brother Abel and killed him. Then the Lord asked Cain, Where is your brother Abel? He answered, "I do not know. Am I my brother's keeper?"

Genesis 4:8-9

" ὁ θεὸς ὁ θεός μου πρόσχες μοι ἵνα τί ἐγκατέλιπές με μακρὰν ἀπὸ τῆς σωτηρίας μου οἱ λόγοι τῶν παραπτωμάτων μου ."

"Deus, Deus meus, respice in me : quare me dereliquisti? longe a salute mea verba delictorum meorum."

"My God, my God, why have you abandoned me? Why so far from my call for help, from my cries of anguish?"

Psalms 22: 2
