This world consists of two dimensions joined as one, like a mirror. The first world, Assiah, is the material world in which we live in. The "mirror" world, Gehenna, is the world in which demons reside. Ordinarily, travel between the two, and indeed any kind of contact between the two is impossible. However, demons are able to pass to our world by possessing anything that exists within it. For example, coal tars are able to possess particles of dust and fungi that surround us. They gather around darkness and around humans with a dark nature.*

Unlike the world of Assiah, we know far too little of the demon world as it hasn't been seen by a human before. It has been stated that Gehenna is an expansive territory with no material present, that has existed long before Assiah. In addition, the only direct way to the demon world is through the Gehenna Gate which only Satan can open. Furthermore, we know that the world of Gehenna is broken into eight or more territories which are ruled by eight sub-kings under the orders of Satan. The following list shows them from what we believe to be strongest to weakest, and what they reign over.

Lucifer, the King of Light, who has shown affiliation with demons such as Seraphims.
Samael, the King of Time, who has shown affiliation with demons such as Phantom Trains, and Death.
Azazel, the King of Spirits/Air, who has shown affiliation with demons such as Ghosts and Furfur.
Egyn, the King of Water, who shown affiliation with demons such as Reapers and Kraken.
Iblis, the King of Fire, who has shown affiliation with demons such as Peg Lanterns and Salamanders.
Astaroth, the King of Rot, who has shown affiliation with demons such as Coal Tars, Ghouls, Naberius, the Impure King, and the Impure Princess.
Amaimon, the King of Earth, who has shown affiliation with demons such as Goblins, Dekalp, Greenman, and Bariyon.
Beelzebub, the King of Insects, who has shown affiliation with demons such as Chuchi.**

You will be able to learn more on these Demons in The Introduction to Demons and The Classification of Demons. As you can see, out in the world there are Demons who are yet to be classified in with the eight Kings, but at the moment further research is still being done on all of them across the world.***

Stupid exorcist, you actually believe that you classified them from strongest to weakest? Sammy gave you the order of oldest to youngest. Oh well.****

"Freshmen representative, Okumura Yukio." As I heard those words while sitting in the auditorium, I closed my book and watched as my twin responded.

"Present," said my twin in a confident tone as he made his way from his seat to the stage.

"The freshmen representative got the highest grade on the entrance exam, right?" I heard a girl sitting in front of me whisper.

"Awesome!"

"Yuuka, isn't he cool?" Ignoring them, I put my attention on my brother as he took out his speech that he was practicing in the limo. I was kind of surprised he didn't have already memorized, after all, he works best under pressure. I could hear the occasional whisper of how handsome my twin look, and how well versed he was to be able to attend True Cross.

Smiling at those whispers, I remembered how weak and emotional was when we were growing up. Constantly being the victim of bullying because of how nerdy he looked, with big square glasses and moles scattered along his face. One memory, in particular, came up, it was after school and he was the first off to head home since I had detention and classroom duty. He was supposed to have already reached the monastery after a fifteen-minute walk, but to my surprise, he hadn't. Instead, he was surrounded by a couple of boys from our class who seemed to be beating. Hearing the soft sniffles of my younger brother, I was quick to take action. That included running up to them and yelling at their direction, that got them to scatter, especially since it was me. I had questioned Yukio if he was hurt and when he gave me an answer I helped him pick up his belongings. As I was doing that, I came across a ripped piece of paper with his dream of being a doctor written on it. I recall asking him if that is what he wished to become and giving him encouragement. Most of all, I can remember that tear-stricken. snot-oozing face with a smile that reached his eyes. I can't believe that the weak-bodied kid, always crying and getting himself bullied, who couldn't even work up the courage to declare his own dream is the teenager standing on the stage right now. Yeah, he's gonna be a great doctor all right. A wonderful doctor who works for the people and the exorcist, I thought in disgust.

"Passing through the gates of the Academy I so admired, I feel nervous just as much as grateful. All the more, I hope we will be able to further our skills through friendly competition. I'm the freshmen and general studies representative, Okumura Yukio." He finished, thank gosh he did, that speech couldn't have been any longer. Sure it was well read and done but seriously Yukio? 15 minutes?

I watched as the other students around me stood and applauded my brother for his impressive speech and his charisma. As the orientation came to an end, the freshman class made their way toward the doors where we would wait for our next set instructions. As I stood in the auditorium courtyard with kurikara and my bookbag on my back, I began to look at my surroundings. The usual coal tars, bariyon, and other lesser demons lurked in the shadows of the buildings, students, and teachers.

I sighed as I looked down at the pavement below my feet and heard the chatter of humans nonstop growing louder as more came out of the auditorium. As I watched swarms of students with their friends come out, I finally caught sight of Yukio who seemed to surrounded by others already. Looks like Mr. Freshmen Representative became Mr. Popular within his 15-minute speech.

"Okumura-kun," the girl who was in front of me during the orientation started. "What faculty are you in?"

It was honestly a simple question, but Yukio somehow had to stutter up his answer with a blush on his face. "T-The Special Advancement faculty for general studies."

"Wow! And you're so tall too!"

Looking away from the new fangirls, I walked around the entire length of the courtyard beginning to get a glimpse at the new group of friends forming. According to Mephisto and Yukio, we had around 200 students in the freshmen class, of which 96 were part of the fine arts program while 104 were of the general studies program. However, only a handful of these students were going to be an exorcist in training at the cram school, literally I could count them all on one hand.

"Freshmen! Listen up," I could hear the loud chatter of the students beginning to settle down as we heard the loudspeaker go off. "We ask students from general studies to please make their way to the school entrance hall, while fine art students stay in the courtyard. The rest of the instructions will be given to you as soon as this is done."

I sighed and began to make myself comfortable by crouching down on the pavement of the courtyard while some students began to make their way to the entrance hall or found a place in the shade to relax. Seeing as it might take a while due to the amounts of goodbyes being made for no good reason, I was about to take out my book until someone bumped into me causing me to fall face first. Feeling the pain shoot from nose to my brain back to my nose was annoying, mind you not as annoying as a certain act, but still annoying. Using my right arm to lift myself from the ground I turned around to look at the person who knocked me down. I gave the person a glare as he glared right back at me with brown eyes, but the glare soon turned soft. Before I was able to yell at him I could hear someone running towards us, Yukio, I could smell him as the air began to change.

"Rin!" I sighed as I turned my gaze from the male to my brother with a worried look on his face. Why of all times does he have to start being overprotective? It's honestly getting annoying right now.

"Are you alright? Are you hurt?" I could hear the concern he had for me, but honestly, I just wanted to beat the crap out of the guy who knocked me over.

"I'm fine Yukio, look, no scratches, blood, or bruises. It was just an accident, right?" This time both our head turned to the guy who had knocked me down. Finally getting over my tunnel vision, I took in the teenager's appearance. The guy looked like a delinquent, how the hell did he manage to enter the academy? Then again, I knew better than to judge someone by their appearance. However, that still didn't stop me from taking in his small goatee, stern expression, a large blond streak running in the middle of his brown hair and several piercings. My mind went immediately to general studies and cram school student.

"Um, yeah, I apologize, I didn't see you there," he said with sincerity. His voice sounded like he meant it, so did his eyes, his body language looked like that of a person who was deeply apologizing, so I nodded.

"It's fine. I guess I'm the one at fault here really, I shouldn't have been sitting on the pavement while others were moving around." Giving the male a small bow, I gave him a shy apologetic smile that I perfected long ago.

"See Yukio? Nothing happened, now stop worrying about me, I'm your big sister for crying out loud it's embarrassing when you worry about me."

"If it wasn't for your hot-headed personality I wouldn't need to worry about you nee-san," he stated. Yukio, you can be a real jerk at times you know that?

Giving him a goofy grin I gestured towards the entrance hall he was supposed to have been in already. "Don't you need to go somewhere little brother? If you don't go now, I will embarrass you in front of everyone, you know I will."

I saw his face pale at my comment, probably remembered the last couple of times I did exactly that when I got annoyed with him.

"Fine, but try not get in trouble on the first day of school for me? What would dad say if he caught wind of that?"

Dad, Satan, would laugh his ass off, and tell my brothers to tell me that I was stupid and could have done better by getting suspended. Dad, Fujimoto, would hit me upside the head, strangled me, grounded me, and make me read the most stupid book of all time, a book about the founder of True Cross, Mephisto. I cringed at the thought of it and mentally gagged.

"Deal."

"Woah, you two are siblings?" Exclaimed a male with pink-dyed hair.

"Technically twins, but yeah," I answered.

"Oh, that is-" he wasn't able to finish since he was cut off by the loudspeaker.

"Attention, all general studies students, this is the last call for you to make your way to the entrance hall."

"You heard your cue, go, have fun doing boring stuff. While I go have fun and doing amazing culinary art," I said with proudness.

Shaking his head, at my utter lack of maturity he left with only a glance of worriedness before leaving.

"We should head out too then, excuse us," I turned back to the guy who had bumped me earlier to see that the pink haired and a boy with glasses had joined him.

"Yeah! See you around," I waved them off as they made their way to the courtyard entrance to catch up with the other students.

It only took ten minutes later for only the fine arts department students to be left in the courtyard. It was at that time that one of the judges from the scholarship assessment was in front of the group.

"As you may all know, this will the department's first year for True Cross. I ask you all to take into account that you all will be held in high regard just as those from the general studies; however, you will also be asked to always be willing to learn in this course for the next three years for those who are thinking about majoring in any of the materials. Furthermore, I expect you all to never let the general studies department intimidate you, always strive to be the best. Finally, I ask for the top student of the fine arts department and the student who had the second highest grade in the entrance to make their way up here."

I could see the students begin to whisper over the fact that the two positions belonged to the same person. I could hear them beginning to whisper on what they would be like. What they didn't see was that the person was already standing next to the judge, and had begun their speech.

"Even though we all belong in a different fine arts course, whether it be photography, culinary, music, or art, we belong in the same department. We are the department that many believe we won't be able to share something with the world, but they are wrong. We are the department, that helps inspire others, help creative minds find a way to express themselves. We may not have an elaborate dream like those in the athletics department of general studies department, but seeing others smiling I believe that is a goal that we inspire to have. I hope we all have a wonderful learning experience that will help us and others in the future to come. I am the fine arts department freshmen representative, Okumura Rin."

My lesson: The best-kept secrets are the secrets that will take others by surprise.

*This is Shiro's explanation about Gehenna and Assiah that he tells Rin in Vol. 1 Chapter 1 of the manga. In addition, I used the following Ao no Exorcist wiki page: wiki/Gehenna#Gehenna

**I got all of this information off of wiki/Demon#Classifications

***Books don't actually exist if they do that is purely coincidence.

****Like I stated before, fanfiction, and I can do whatever I want. I know this is actually the strongest to weakest list thing, but let's keep this going shall we? I'm just filling in the gaps of other info that hasn't been told yet for the sake of this story.

To be honest, I feel like this chapter was too choppy? I guess that's the word. I'm honestly not liking this chapter that much, don't worry I'll make that up in the next chapter. Next up, exorcist cram school!
