Yukio Okumura entered his classroom on the first day of the new school year at the Cram School within True Cross Academy. The classroom was currently empty, as it was not yet time for classes to start. Yukio had decided to use this time to prepare his class. He was currently 15, the youngest exorcist ever, hailed as a prodigy by was his first year teaching at True Cross, but he had plenty of confidence in his own abilities as an exorcist. He had only improved since his adoptive father's death five years ago. But that was a distant memory now. He put his bag on the table and began to go through his things.

Yukio had brought two pistols with him, his main weapons as his mix of a Dragoon and Doctor. He used those pistols offensively against demons while also being able to heal his teammates as a Doctor. His guns were loaded with blessed 9mm silver bullets. The perfect round for taking on most any demon. Yukio put them in the holsters under his arms that were hidden by his trench coat. To the untrained eye, it looked as if he wasn't even carrying weapons. Yukio then got out his supplies for teaching. Pencils, pens, paper, all the necessities. He then felt something in the bottom of his bag. He pulled out a frame with a photo. It was a photo taken 5 years ago with him, Fujimoto, and Rin. It was the last photo they all took together, and it wasn't long after that day that everything went wrong. Tears began to well up in Yukio's eyes as he thought back to his last few days with his father, and with Rin.

Shiro Fujimoto stood in the open doorway to the monastery with an angry expression. There was a ten year old Rin Okumura outside with a police officer holding him by the arm. Rin had just gotten into another fight, and this time had been stopped by an officer who had seen the whole thing. He had pulled Rin off the other boy and took him into custody. This wasn't the first time Rin had done this, so the officer had decided to just escort Rin back home. Fujimoto was now staring down at him in disapproval. He then smiled to the officer. "Thank you for taking him home officer, i'll make sure he learns his lesson." Shiro apologized to the cop, taking Rin in his own grip now. The officer nodded at Fujimoto.

"No problem, you have a good day now Mr. Fujimoto." The officer replied. Shiro waved goodbye as the officer left, then promptly closed the front door to the monastery. He then turned around and gave Rin another furious look.

"Alright, what was it this time?" Shiro demanded.

"He deserved it, that guy was shooting birds for fun!" Rin shouted in defense.

"So you got into a fight with him?" Shiro scolded the boy.

"Yeah, someone had to do something!"

"Did that someone have to be you though Rin?" Shiro asked.

"Well why not?" Rin asked back, starting to calm down a bit.

"Rin, there was a police officer close enough that he saw you throw the first punch. Why not go to him? Or go find the other boy's parents are tell them what was going on?" Rin didn't have a response to that. He decided to remain silent and stared off away from Shiro. "Rin..." Shiro knelt down and put a hand on Rin's shoulder. Your heart's in the right place, but you mustn't take it upon yourself to take care of every situation by yourself. The world has a lot of problems, and it's too much for any one person to handle alone."

"Well I can still help however I can right?" Rin shot back, looking back at his adoptive father with an look of intensity. "You'll see, one day i'll become stronger and i'll help out the whole world!" Shiro gave a hearty laugh.

"The whole world huh, is that right?"

"Yeah!" Rin repleid without any hesitation. Shiro laughed again.

"We'll see about that. But if you're going to bulk up and get strong you need to eat. It's time for dinner so eat up, everyone's already inside." Rin smiled with delight at the mention of food. He ran into the dining room, with Shiro following behind him. Rin took his place next to his brother Yukio, who was currently reading a book. Shiro took his seat at the head of the table and dinner officially began. "Sorry we're late." Shiro apologized.

"Did Rin get into another fight again?" Yukio asked, still staring down at the book in his hands.

"Heh, it wasn't a fight it was a bloodbath. The cops had to come and pull me off that guy." Rin gloated.

"You say that like it's a good thing." Yukio responded, looking over to his brother.

"Now Rin tells me he's going to save the whole world." Shiro told the others.

"Oh is that so?" One of the other priests living at the monastery commented.

"You bet!" Rin shouted with confidence. "I'm going to get really strong and protect the whole world!"

"Well then you better eat a hearty dinner. Gotta get big and strong." Another priest told him with a smile. Rin decided to listen and grabbed a pate full of food. He began to dig in, quickly eating as much as he could.

"Hey, maybe you could become a priest and run the monastery someday." Shiro commented. "That'd help a lot of people."

"It would?" Rin asked.

"Of course, plenty of people come here everyday for helps in all sorts of things." Shiro explained. "We help out the whole community around here. Even your brother Yukio is studying to become a priest."

"Wait, I thought Yukio was going to be a doctor." Rin asked confused.

"I am. But i'm going be a doctor wherever they need me to be one. So i'll be at some monastery somewhere too, hopefully this one." Yukio clarified. "I'm studying everything from religious text, to modern medicine, to exorcism."

"Exorcism?" Rin repeated in confusion.

"Yes, exorcism, as in fighting demons." Rin's face lit up a bit when Yukio put it that way. "Plenty of people rely on exorcists for supernatural matters."

"Really? Well then i'm going to become an exorcist too!" Rin declared. Everyone in the room stopped eating and gave him a surprised stare. Rin faced his brother with confidence. "One day, let's both become the best exorcists we can be and help out as many people we as we can." Yukio was taken aback by this for a moment, surprised to hear his brother say such a thing. He then smiled back.

Alright." He agreed. Rin grinned with glee and went back to eating his meal. That was the last time they had dinner together.

Two days later, Rin was standing by Shiro's grave in the nearby cemetery. The night prior was when everything went wrong. Rin had run into that boy from the other day, only something was different. The other boy began suddenly began to change into a non-human shape. Rin would have gotten his tongue burned out with a red hot metal rod too if Shiro hadn't shown up. He tossed the boy to the ground and exorcised him right there. Shiro then explained Rin's origin, and that he was the son of Satan. Shiro led Rin back to the church but they were followed, Astaroth, one of Satan's Demonic Kings had followed them. After a brief skirmish, Rin came back and scolded Shiro for abandoning him. Shiro had become weaker in that moment and then became possessed by Satan. Satan had opened a gate to Gehenna in the floor and attempted to drag Rin. He was stopped when Shiro momentarily regain control and sacrificed himself to save his son. Rin stopped the Gehenna Gate and saved himself and Shiro's now lifeless body. Now Rin could only pay his respects in the rain.

He was currently dressed in a black suit and looking down at the grave with a sad expression. He had his sword Kurikara holstered on his back, held there by a sling. The rain only worsened the already dreary mood. His father, who had adopted him at a very young age, was now dead because he sacrificed himself in order to save Rin. Rin couldn't help but feel a little bit guilty as he stood there lost in his thoughts. He did not even hear anyone approaching until they were next to him. When Rin noticed he wasn't alone he looked to his right to see Yukio there. Yukio was dressed in a black trench coat, and although Rin did not know it at the time, that was the attire for most exorcists. Yukio had an unmoved look on his face, almost like a statue. There were flowers in his hands, a small bouquet of them. "Yukio, where have you been?" Rin asked. Yukio didn't respond. He bent down and put the flowers at the foot of the grave. "I haven't seen you since yesterday before dad died. What happened Yukio where were you?" Again, Yukio didn't respond. "What's wrong? Why aren't you answering me? Say something Yu-" Rin stopped talking when Yukio suddenly pointed a gun at him. Yukio had a single pistol aimed right at Rin's head, his finger on the trigger. "What... what's the big idea?" Rin asked, bot confused and scared.

"I know everything Rin." Yukio finally said something. "I've known all along about you, and about your powers."

"What, you knew?" Rin was startled to learn the truth.

"For as long as I can remember, i've been able to see Demons. Father helped me, taught me to not be afraid anymore. Ever since that, i've tried devoting my life to becoming an exorcist, just like him. Something else I know, is that there's no one Satan would want to possess more than dad. But dad was too strong willed to allow that, he would never let Satan in. So something must have triggered him. You said or did something, didn't you?" Rin thought back to that night, how he yelled and berated Shiro for lying to him all those year. After calling him a pretend father, Shiro then slapped the boy for saying such a thing. Rin held his head down and began to choke out sobs. He then looked up tearfully to Shiro and begged.

"Please, you're supposed to take care of me, you can't just abandon me." That must have been it. At that moment Shiro felt heartbroken, and Satan managed to get it. When Yukio explained it, it made sense to Rin. It was his fault, their father was dead because of him.

"So you're going to shoot me then, is that it?" Rin asked, a bit furious now. Yukio glared at Rin from the other side of his gun.

"No... If I killed you father would have died in vain." Yukio lowered his gun. "But I want you to leave. Don't ever come back to the monastery or let me see you again. Because if you do, then i'll shoot you." Yukio turned his back on Rin.

"What? Yukio, you can't be serious." Rin fought back.

"Did I not sound serious?" Yukio asked, his voice more dull and lifeless.

"You can't do this, you can't abandon me like this. You're my brother!" Rin pleaded.

"I have no brother!" Yukio shouted back in anger. Rin gased in horror at what he just heard, staring wide eyed as Yukio faced away from him. "Now get out of my sight." Yukio then began to walk away. Rin just stood there in the rain and hung his head. He had just lost his family and his home. He was all alone now. The next day, exorcists came to the monastery looking for the son of Satan in order to get rid of him. But it was too late. Rin had vanished, no one knew where he was. There was a brief search that lasted a few months but ended up with nothing. The case went cold, and soon faded from everyone's memory. But eventually it would return to Yukio years later.

Back in the present day, Yukio was beginning to cry. He silently cursed himself for being so dumb. After a few years had passed, Yukio began to regret what he said that day. He regretted telling Rin that they were not brothers anymore, and for abandoning Rin like that. He hadn't seen him since that day either. No one who knew Rin Okumura had any idea what happened to him. It was as if he vanished from face of the earth. Yukio didn't even know if he was still alive or not, and that thought scared him. He would never forgive himself if Rin was found face first in a ditch somewhere.

There was then a rasping on the open door. "Knock, knock." Professor Tsubaki, the Physical Education teacher at the cram school, was at the doorway to Yukio's classroom. "Just coming to check on you on your first day-" He cut himself short when he saw the tears in Yukio's eyes. "Is everything alright?" He asked, sounding rather concerned.

"Yes, i'm fine." Yukio answered, wiping the tears from his face. Tsubaki came over to make sure he was really ok. He then noticed the picture in Yukio's hands.

"Hmm, who's that?" He asked. "With you and Fujimoto."

"Oh, that's Rin. He's my brother." Yukio told him, now smiling a bit.

"Brother? I didn't know you had a brother."

"Yeah, a few years ago we got into a fight when our father died. I told him I never wanted to see him again, I got my wish." Yuki explained.

Oh my, i'm sorry to hear that." Tsubaki showed his sympathy. "What happened to him?"

"I don't know. He ran away after that. I haven't seen him since." Yukio replied.

"Oh dear, well i'm sorry to hear about that. It must be hard."

"It's fine, I just hope he's alright." Yukio stared back at the lat photo he had with his family. Tsubaki stared down at him with a saddened look.

"Well I should probably let you get back to it, the ceremony will be over soon and the students will be arriving." Tsubaki reminded his fellow professor.

"Ah, right." Yukio replied a bit blankly. Tsubaki then exited the classroom and Yukio finished preparing. After about a half and hour students began to enter the classroom. "Welcome to your first day of cram school." Yukio greeted the first three that entered. "Names please."

"Ryyuji Suguro sir!" The bot in the middle with two color hair and piercings reported.

"I'm Konekomaru Miwa sir." The short boy to the left spoke up.

"And my name's Renzo Shima." The last one with reddish-pink hair introduced himself last. Yukio nodded and marked them as present, then then three boys took their seats nearby one another. The next student walked into class a few moments later. He was a rather mysterious man who wore a grey cloak concealing part of his face.

"Name?" Yukio asked.

"Yamada." The man spoke in a deep voice. He then went and took a seat in the back of the class. Two more students came in not long after that. Two girls, one with purple hair tied in twin tails behind each shoulder. The other had short brown hair in a bob cut and green eyes. They both wet up to Yukio's desk to report in.

"Izumo Kamaki." The girl with twin tails told the teacher.

"I'm Noriko Paku sir." Noriko introduced herself a bit more shyly. Yukio nodded and smiled to them, marking them down.

"Well it seems like we're just waiting on one more person." Yukio commented aloud. Then as if on cue, there were footsteps as the last student entered the classroom. "Speak of the devil, name please?" Yukio asked and looked up. Then his heart skipped a beat. Now standing before him was a 15 year old Rin. Rin looked different than he had five years ago. He was not only taller, but he had allowed his hair to grow out longer. It was now just a few centimeters below his chin, and partially covering his face on the right side including his right eye. His expression had changed too. He went from that look of determination Yukio was used to to a jaded and almost lifeless look. He was wearing a black leather jacket with the zipper open over his school uniform. He was also carrying two swords on his right side. They were crossed making an x shape, meeting at his waist. The one with the handle on top Yukio recognized as kurikara. The other was not one Yukio had seen before. It was sheathed in a white scabbard, and the handle was also white with a silver hand guard. Rin gave a stone faced look to Yukio as they met for the first time in five years.

"Rin Okumura." He responded as if he was a normal student who had never met Yukio before. Yukio nodded, still looking rather surprised. Rin turned away and took a seat and the table in the middle of the room. Some of the other students were thrown off by their teacher's sudden reaction to Rin. Yukio then stood up from his desk.

"All right, welcome to your first day of training to become exorcists." He greeted the class, now collecting himself. "I will be your teacher, Professor Okumura." Some of the confused students from before now began to wonder if he and Rin ahd some sort of connection. Rin just sat there motionless as if he as just another student. "As you know, our world consists of two planes, Assiah and Gehenna. The realm we live in is Assiah, while Gehenna is the twisted place of reality where all demons come from. While most can not enter our world some manage to get over, and it is our job as exorcists to remove these demons. Now, before we begin does anyone not have their temptaint?" Both Paku and Konekomaru raised their hands. "Alright, come to the front of the class and allow me to give you your temptaint." The two students walked up to the front, feeling a bit nervous. Yukio pulled a small vial of a deep red liquid out from his bag. "This is goblin's blood. If it makes contact with your skin it will summon a few harmless goblins as well as give you your temptaints. Now, give me your arms." Konekomaru and Paku both held out their right hands, with the palms up. Yukio rolled up their sleeves and uncapped the top to the vial. He gave them each a drop of blood on their arms. The blood fizzled and soon became steam on their arms. Then out of nowhere, a few goblins appeared in the air around the class and began to float around. Some of the students stared at them, this being their first time seeing the creature.

"These are goblins." Yukio explained. "They are low level demons that are pretty harmless. They can't do much on their own besides cause mischief." Yukio was about to regret those words. One of the goblins bumped into the hand he was holding the vial with. The vial fell from his grip and crashed against the ground. The smell of rotten eggs filled them room, making all but Rin cover their noses.

"Ugh, it stinks." Ryuuji commented.

"It smells like rotten eggs." Konekomaru remarked in a nasally voice as he covered his nose.

This isn't good. Yukio thought to himself. At this rate this much blood will... He suddenly heard somethign appear behind him. He turned around to see a rather large goblin appear in the class. Konekomaru and Paku both backed up a few feet in fear.

"What is that?" Paku asked frightened.

"Crap, it's a hobgoblin!" Yukio shouted. The large monstrous goblin opened its maw and began moving forward towards the class. "Everyone stay back, i'll-" Suddenly there was a swift wind and a brief flash. Rin was suddenly on the other side of the hobgoblin, which had stopped moving now. Rin had his white sword drawn, revealing the blade was made out of silver as well. The blade was out horizontally towards the hobgoblin. The demon then split into two down the middle and howled. It dissolved into a black mist and faded from the class. The otehr few surrounding goblins did so as well. Rin stood back up, having taken a knee after stopping. The others in the class all just stared at him in marvel of his speed. Yukio had his hand on his gun but hadn't even drawn it by the time Rin reacted. He was now staring in shock at Rin's abilities.

"Apologies sensei." Rin begged pardon. "The angle of my cut was off by a few degrees and the blade was dulled as a result." He spun the blade up in a circle and let the tip into the sheath. He let go and let it slide back into place. "I'll do better next time."

"That's... fine. You did a good job Mr. Okumura." Yukio told him.

"Geez, this guy cut through a demon like that and apologized for it?" Ryuuji quietly commented to Renzo. Renzo nodded in silent agreement. Rin then walked back to his seat and sat back down. Yukio let go of the pistol and pulled his hand out of his coat.

"Alright, now that that is over let us continue on with class."

The rest of the day was normal, Rin went to his classes as scheduled and then afterwards went to the dormitory set aside just for him. It was the old male dorm that was no longer in use. Rin would have the whole building to himself in order to train and protect his identity as the son of Satan. Rin looked up and stared at the old building with a stoic face. He then entered the old building and had a walk around to find where everything was. He picked out one of the old rooms and threw the bag with his things down by one of the beds. This was his new home now, a place for him to stay. He heard the doorknob turn and the door creak open. He instinctively reached for his lower sword. When the door opened up her saw Yukio standing there in the doorway. Rin stared at him in silence for a moment.

"There you are. I'm going to be your room mate during your stay at True Cross." Yukio explained with a smile. Rin was silent for a moment, his hand still on his white sword.

"Very well." He replied in an apathetic tone, letting go of his sword. He then picked his bag back up and walked towards the door, walking past Yukio. "But i'm having my own room while we stay here." Rin told his brother. He then went over to the room next to Yukio's and entered that. Yukio smiled as he vanished from sight. He was different, but at least he was alive. Finally after all those years he had Rin back, and he could begin to fix what he did five years ago.
