Chapter I – New Arrival

Have you heard of gods, angels, devils, and other supernatural beings? Humans thought they were just legends and myth, thought up hundreds of years ago.

But even legends had to start from somewhere.

What humans had long believed to be mere myths and legends, were actually true. They existed, the supernatural. And they were very much real.

Heaven and Hell existed and that, in turn, created the Three Factions. Angels, Devils, and Fallen Angels. For a time, these three coexisted with one another. Maintaining a certain balance of good and evil.

The Three Factions started thousands of years before the start of the story after the Biblical God cast out Angels that opposed his teachings, creating the Fallen Angels who inhabited in the Underworld alongside the Devils.

But unlike other supernatural groups such as the Norse Gods, Hindu Gods, and Greco-Roman Gods, which were apparently more or less independent of each other, these three factions were all interconnected. Together, the Three Factions spawned the Judeo-Christian religion, and became part of the Bible.

But war was inevitable.

Though the exact reason was lost over the passage of time, tensions rose between the factions to the point where conflict was unavoidable.

The war, that has come to be known as the Great War, lasted for thousands of years with all three sides losing great numbers of warriors. But it was the Devils that suffered the most losses.

While it is true, that Angels and Fallen Angels are at odds with each other, they still originated from Heaven and thus had an unspoken agreement to join forces against the Devils.

But the war was finally put to an end by the Kuoh Treaty and the deaths of the Biblical God, and the Four Great Satans. Unbelievable as it may seem, it is true. God had died in the war and only a select few knew of it.

But it was an uneasy truce. True that a cease fire between the factions had been enacted, animosity still ran rampant within their ranks. And the occasional skirmish had been wrought out.

Now, centuries after Michael, the Right Hand of God, and the new Four Great Satans, Sirzechs Lucifer, Ajuka Beelzebub, Serafall Leviathan and Falbium Asmodeus, and the leader of the Fallen Angel Organization, Azazel, had signed the treaty, the world could now heal from its wounds.

Today, the peace was still fragile but at least the factions were coexisting again

And now, in present Japan, stood Kuoh Academy. Though to the rest of the human race, it was just your typical academy, but it was far more than that.

The academy is actually Devil territory where the clans Gremory and Sitri have dominion.

At first, the academy started out as a girls' only institution, but the time came for change so it was converted to a co-ed school and new buildings were made to accommodate the new students.

It was just another day for Kuoh Academy. Another typical school day for the students, another day of learning, and for a certain three boys…it was another day of being perverts.

"C'mon, man! Don't hog it all to yourself!" A boy whispered, trying to squeeze himself to the peep holes to see their intended target. This was Matsuda, a member of the infamous Perverted Trio.

"Shh! Be quiet of they'll hear us!" A second boy said. This was Motohama, another member of group.

On the peephole was none other than the revered leader of this perverted group, Issei Hyoudou.

What were they doing? Well, it has something to do with watching the Kendo Club taking showers. They didn't get the moniker, the Perverted Trio for nothing after all.

Issei felt himself getting hard down there as his nose bled. 'Oh my god, this is heaven!' He squealed to himself. 'So many oppais! Oppais, oppais, OPPAIS!'

"Issie, c'mon, lemme get a look!" Motohoma whined as he and Matsuda pulled Issie down from his perch. "You had your turn, now it's mine!"

"Oh no you don't!" Matsuda grabbed his glassed comrade by the collar and pushed him aside. "It's my turn to witness the beauty of oppais!" He giggled perversely, climbing up the box.

Motohama was having none of that though. "Get your ass back here! It's my turn to stare at oppais!" They began to have a scuffle where Issei joined in.

"You idiots! I was this close to see Murayama-san's tits, and you two robbed me of that chance!" The perverted boy screamed to the heavens as he tried to beat his friends some sense.

"So…you three dead men at it again, eh?" The Perverted Trio stopped dead in their brawl, all color draining from their faces.

Looking at the side, the boy's fears skyrocketed when they saw about a dozen enraged looking girls in robes with kendo sticks in hand. And they were staring at the boys with the fires of hell.

"Hehe…hi, M-Murayama…" Issei stuttered out nervously.

Said girl just growled and raised her kendo stick high over her head. "PERVERTED ASSHOLES!"

All over the academy grounds, students could hear the screams of agony of some poor souls that dared to peep at the Kendo Club.

In a certain room of the school was where the Kuoh Academy Student Council resided. Currently, the president of the Student Council was Souna Shitori, but do not be fooled. Her real name is Sona Sitri, a devil and heiress to the Sitri Clan.

Sona had heard the high pitched screams and couldn't help but shake her head in annoyance. "There they go again. Getting caught doing their immoral acts." She sighed irritably.

Sona Sitri was by all means, a very beautiful young woman. She is a young bespectacled woman in her late teens with a slim figure, black hair styled in a short bob cut and violet eyes. Personality wise, she has shown to be a very strict and intelligent individual. Whether it is a matter of the Student Council or the Sitri Clan, she does not take anything lightly. But despite all this, she is a very caring person and dedicated to those under her.

But for a certain group of boys…Sona was considering to fall to the temptation of approving Murayama's request of castrating Issei and his cohorts.

She swore the bastards had been eyeing her when she wasn't looking.

"And does that surprise you still?" A red haired girl in front of her giggled. "You know how they are." The girl then moved a chess piece on the board. "Your turn, Sona."

This was Rias Gremory, the most popular girl in the academy. Rias is a beautiful young woman who appears to be in her late teens with white skin, blue eyes and a buxom figure. Her most distinctive feature is her long beautiful crimson hair that reaches down to her thighs, with a single hair strand – also known as ahoge in Japanese – sticking out from the top. Her hair also has loose bangs covering her forehead and side bangs framing her face.

Sona moved her piece and had claimed one of Rias' own. "You seem to be getting better, Rias." She commented. It was no question that Rias and Sona had a bit of a rivalry going on between them, but they were still good friends.

This was just a friendly bout.

Rias gave a smile. "Thanks. But one day, Sona. Mark my words, I will defeat you." Rias declared with determination. Ever since she was little, she and Sona had this fierce rivalry…though it wasn't anything serious, just friendly.

They would subtly compete over everything to see who was better, especially when it came to chess. Clearly, Sona had Rias beat on this but the Gremory heiress would not cry uncle until she tasted sweet victory at last.

"Maybe." Sona said. "But that day hasn't come yet." She moved her queen…victory was hers. "Checkmate, my old friend."

Rias just gave out a sigh. This was already won by Sona by the very beginning, but she was getting better. "Hmm, well. Don't get too cocky, Sona." Rias stood up and went to the door. "Maybe someone could actually be a match for you." With her piece said, Rias went out the door.

"Hm, maybe." Sona mumbled while she cleaned up the board. While it was true that Sona was glad she won, it was a hollow victory. Rias was getting better but she was nowhere near her level yet.

Sona wanted a challenge.

Once Sona was set to be married, but she called it off when her fiancé couldn't defeat her in a game of chess. The boy was nice, but Sona made it clear to her parents that she would not marry someone who was not smarter than her, or at the very least, could give her a satisfying challenge.

That, and she was too proud to admit defeat anyway. But if defeat did befall her…well, whoever had done that to her would have her respect.

After finishing with the board, the Sitri heiress went to her desk to look over some documents and requests by the student body and the teachers as well.

'Let's see what we got here…' She mumbled to herself, flipping page after page of papers. It was the usual deal for her. Some complaints here, some requests there, with a little bit of event organizing on the side.

Then she came to the part where she couldn't help but roll her eyes. Another request by the Kendo Club to hunt down the Perverted Trio and roast them alive in a bonfire.

'How glorious would that be to watch those breast addicted perverts to burn at the stake.' Sona thought to herself, imagining the cry of pain those three rightfully deserve for dishonoring women.

But alas…she had to refuse that pleasure for now.

With great reluctance, Sona stamped 'Denied' on the request form, but soon…retribution will come. For now, though, the female population of Kuoh Academy would have to endure the Perverted Trio's existence for a while longer.

"And that should do it." Sona said to herself. Everything was done with and she could get on with her day. Looking at the clock, she saw that it was a little over eleven so she still had time to rest as her classes doesn't start until noon.

Stretching her lithe form a bit, Sona prepared to leave the room and maybe grab a snack before the next batch of her classes began. But something had caught her eye.

It was a file that had a note attached to it. 'How did I not notice that before?' She asked herself. Sona picked up the file and read the note.

Sona, this is the Academy Head. I wish to inform you that we will be receiving a transfer student in the coming days and his credentials and bios are in the files. When he arrives, I request that you to show him around and give him a brief tour.

Thank you.

"A transfer student?" Sona was confused, trying to recall this in the past days but nothing came up. This was probably a last minute thing.

But who was this new transfer student? Well, there was only one way to find out. Opening the file, Sona could now see who was going to be in their care.

*One Hour Earlier*

"Attention passengers, this is your Captain speaking. We are currently on our final approach to Haneda Airport. Please fasten your seatbelts until further notice. Thank you." A Japanese voice said over the speakers and the passengers began to clasping their seatbelts with the attendants helping however they can.

In the first class cabin, the folks there too were getting ready for landing.

A flight attendant was making rounds, inspecting each person if they were secured for the landing as airplane landings can be somewhat rough. So far, everyone was secured except for the last one.

In the far corner of the cabin was a young man in his late teens, seating cross legged and was reading a book. He had shoulder length black hair that was messily slicked hack and a single lock dangled down his face. He wore dark blue jeans, a dark blue button down shirt with a purple vest, a black overcoat, and a scarf around his neck styled as a tie. He had headphones on and his foot was tapping to the beat.

The boy was extremely handsome with pale skin and sharp features having been a mix of European and Asian descent.

On the young man's lap was a sleeping cream colored Sphinx kitten whom he was affectionately rubbing with his free hand.

Seeing that calling him by words was no use thanks to the headphones, the stewardess opted to just tap him gently to catch his attention. Stretching an arm out to him, she tapped his shoulder and that got his attention.

Feeling something, the young man turned to his right and saw that one of the stewardesses was there with a smile. Withdrawing his hand from his kitten, he took his headphones off just in case he missed something. "I'm sorry. What was that?"

The stewardess couldn't help but blush when the young man faced her. She would admit, he was very handsome for his age, and especially his eyes. They were two different colors, blue to his right and purple to his left; Heterochromia Iridium, a rare genetic disorder that gives a person two eye colors though it was just an appearance issue. And...it was very nice to look at.

Shaking these thoughts away, the stewardess faced the man with a friendly smile. "We are about to land, sir. So, please fasten your seatbelt."

"Oh, thank you." The man said in a refined tone with a smile of his own that made the stewardess blush brighter.

'Get a hold of yourself, girl! He's too young for you!' She said to herself before moving along. But she couldn't deny that the young man was very attractive. Though unknown to her, the man did see her blush.

It goes without saying that any man would feel pride when droves of women swoon over them. The same could be said for our young fellow. Though unlike the majority of the male population, he doesn't take too much pride in it.

He placed the book inside his overcoat and gently nudged his kitten awake. "Wake up, Pip. Time for this plane to land." He said and eventually Pip opened her forest green eyes with a cute yawn. Pip was only a few months old so she was still rather small.

Pip looked up at her master, wanting to know why her precious sleep was interrupted so.

"Don't give me that look, young lady. You've been asleep for the entirety of the flight." He chuckled and swore he saw his kitten roll her eyes at him. Smirking, he picked up Pip and placed her inside his breast pocket, being small did have its perks when your pet could still fit in your pocket.

The kitten popped her head out from the pocket and made herself comfortable. She gave her master and friend and lick to his chin before she started swatting at his scarf.

Once his seatbelt was fastened, the man took a breath and laid back in his chair. He looked outside the window and saw the city of Tokyo drawing ever closer.

"Well, Pip. This is going to be hjem (home) for us for a while." While addressed to his cat, he knew he was mostly talking to himself as the kitted was busy nibbling on his scarf. 'Cats...just as unpredictable as women.'

He laid back further into his chair as the aircraft began its final approach to the airport, pondering on how this came to be.

The young man was born of Norwegian and Asian blood and had spent most of his life in his homeland. He came from a very wealthy family, but unlike most of them, he had a wonderful childhood. His parents were happily married and he loved them dearly.

But...he just couldn't fathom why his mother would send him halfway across the world to a new school. In Norway, he had been studying in the Norwegian University of Science and Technology pursuing a degree in Engineering and maybe a minor in Musical Arts and Literature if he had the time even though he was still a high school student.

Now, like most students, he had his moments but that doesn't mean he was a total trouble maker. His grades were among the highest in his class, the professors and students respected him, and he was the captain of the Martial Arts Club and he felt no shame when he says he was the best.

Though despite all of this, he was not a very social person. The young man would prefer to keep to himself but not to the point of being a tried and true recluse. He still knew how to have fun and had good friends back home...though he wouldn't call some of their certain escapades fun.

A shiver run up his spine when he remembered those moments. 'Herregud (Oh my God), I'm lucky that father and mother don't know about that...yet.' Sometimes he wondered why those idiots he calls friends never ended up in the military...or prison for that matter.

But we digress, things were great back in Norway, so...he couldn't understand why his mother wanted him to study in Japan, of all places.

He had tried to persuade his mother to reconsider, hell, even his father tried talking her out of it, but the woman was as stubborn as they come so he had no choice but to comply.

His mother had explained to him that this was just for him to see the world and not being cooped up in the house doing nothing but listening to music, writing stories, and training with his father and uncle in martial arts.

And just being lazy which he silently disagreed with. Him, lazy? HA! …Well, maybe a little.

Of course, him, his uncle, and father argued that it was something and that only got them all a hard bonk on the head. He could still feel the soreness on his head and he was pretty sure the bump was still there.

If anything, he was just glad he could bring his cat along. The young man just smirked. As annoying and as sassy as this little bugger may be, she was still his closest friend.

"Will you stop that?" He asked his cat who was still playing with his scarf. Pip gave him a brief glance before resuming her fun as if to say 'Faen o' or 'Fuck off'. Yep, that's Pip for you.

'Well...this may not be a total loss.' He thought to himself. He means' c'mon, this was Japan! The Land of the Rising Sun, the land of anime, otakus, animal girls, girls that don't look their age, outrageous gameshows, oversized breasts, tentacle porn, hentais...

'...Well, that's certainly no good...' He though in a deadpan expression. 'But at least the food's going to he something else.'

If there was one thing that he looked forward to in going to another country, it was the food. He rarely travelled out of Norway but every time he did, he always wanted to try new foods. It's kind of a hobby for him, wanting to taste new things. But he did have his favorites.

Aside from being an engineer and an artist, he also had a knack for the culinary arts. Something his father, a well-known food critic, had passed onto him. He would sometimes experiment on different ingredients with back home under the supervision of the family chefs, of course, lest he accidentally blows up the house again.

...He didn't want a repeat of that but all things considered, he had gotten better with his cooking skills.

"Attention all passengers, this is Captain Shin Yamamoto. We have arrived at Haneda Airport. We thank you for flying with Tokyo Air, and I bid you all a good day. Thank you and have a nice stay in Japan."

The young man was broken out of his thoughts when he learned that the plane has stopped and the other passengers were all preparing to disembark. "Huh...how 'bout that." He muttered to himself and went about unbuckling himself.

He heard some light hissing coming from his pocket and couldn't help but roll his eyes. "Yeah, yeah, laugh it up, you little rotte (rat)." He mumbled out as the buckle came apart and he moved out of his seat.

The kitten appeared to take offense to that and used her tail to thwack his cheek. It didn't hurt, of course.

"What a hothead." He chuckled as he opened up the overhead compartment and took out his duffle bag and slung it over his shoulders. "Well...this is it. Goodbye Norway, hello Japan."

He made his way out of the first class cabin, the flight attendants moving the passengers along and saying their goodbyes. One stewardess, the same one who he caught blushing at him, waved goodbye which he could see was a little too friendly.

But nevertheless, he gave her a smile and a curt nod before exiting the plane and into the terminals. He would admit, the woman was fine looking and nice, but she was out of his age range.

Once he was out of the tube and into the main terminal, he breathed in the new air and sighed. 'Things might get interesting while I'm here.' He said to himself and he replaced his headphones back onto his ears and clicked on his iPhone to play some music.

Walking with the other passengers, he came to the pickup belts where he waited for the rest of his luggage to come. It didn't take long for it to come along and he hauled it out of the belt.

Extending the handle and pulling it alongside him, he made his way to the check-out station with his ticket and passport in hand.

"Next, please." The clerk said and our young man came forward.

"Kon'nichiwa." ("Hello.") He greeted in perfect Japanese and handed his documents to the clerk who was surprised as how fluent he was.

"Well...I guess I won't be having trouble with speaking English with you." The clerk chuckled as he looked over the documents. "Where'd you learn how to speak Japanese?"

The young man just shrugged his shoulders. "From my father. He spent quite a bit of time here in his youth and on business trips as well. It's not really my first time here as he sometimes takes me here on the holidays."

"Ah." The clerk nodded. "That's understandable. You learn a few things from other places, right?"

A smirk played on the young man's lips. "Correct."

Giving out a chuckle, the clerk resumed going over the documents. "So...what brings you to Japan? You look like you're gonna be here for a while." He eyed the boy's luggage.

"Yes, I'm gonna be here for a while. I've been transferred by my mother from my previous school in Norway to here." The boy sighed.

"Hm, well. What school did she send you?"

"Something called Kuoh Academy. Ever heard of it?"

The clerk gave a smile and nodded. "Yes, I have heard of it. Well, at least she sent you to a fine school. You can expect one of the best educations Japan has to offer there."

"I'll take your word for it."

Satisfied with what he's seeing, the clerk took out his stamp and cleared the ticket and the passport and gave it back to the young man. "Here you go. Enjoy your stay in Japan." He said with a friendly smile.

"Dōmo arigatōgozaimashita." ("Thank you very much") He returned the smile and went on his way as the next passenger took his place.

After having his luggage and person checked for anything suspicious, the young man exited the airport and finally laid eyes onto the place where he would call home for a while.

'Well...it's a lot different than I remember.' He thought to himself but shook it off. He adjusted his duffle bag on his shoulder and he looked at the crowd for his ride into the city.

His parents had made the necessary preparations for his arrival and they had bought him penthouse in the Mandarin Oriental. But first he had to get there.

Giving the crowd a once over, he saw someone holding a sign with his name on it. He figured that was his ride their so he went to the middle aged man.

The man seen someone coming towards him and assumed that this was the one he was sent to fetch. "Hello, are you by any chance the one I'm sent to pick up?"

"I am." The young man nodded and bowed his head in respect as is customary in Japan. "A pleasure to meet you.."

"A pleasure to meet you as well." The man gave a smile and bowed in return. "Come, my car is this way."

The two of them went to the parking lot and eventually arrived to the older man's vehicle. It was a brand new Toyouota but the younger man didn't pay attention to the detail.

The trunk opened up and he put in his luggage and duffle bag in it and proceed to enter the back seat.

"I'm supposed to take you to the Mandarin Oriental Hotel. That should take about thirty minutes depending on the traffic."

"Okay." The younger man said, getting himself comfortable just as Pip jumped out of his breast pocket and onto his lap.

The ride didn't take long for them to reach the hotel and after thanking his chauffeur, the young man entered the lobby. The reception staff took notice of him and were instantly on him, asking if he needed some assistance.

"No, thank you." He declined curtly and made his way to the desk.

The receptionist looked at him and smiled. "Welcome to the Mandarin Oriental. Would you like to rent a room? We have one of the bests services and facilities around."

"Arigato but that won't be necessary. I assume there is a penthouse bought under a certain name here?"

The receptionist nodded and checked the records. And there it was. "Ah, the penthouse suite. May I know your name, sir, so we can verify it?"

The young man smirked and looked at the receptionist in the eyes.

*Kuoh Academy*

Sona laid the file down, having finished going over it. Kuoh Academy was about to get a new student...and if these files were correct, he was one hell of an interesting character.

"Hm, Kyuren Kaizer Avynzen, huh?" A new student coming to Kuoh? Well, it's not the first time it happened and it certainly won't be the last. So she had nothing to worry about since this was just a normal occurrence.

But unknown to the Sitri heiress, things were about to change. For better or worse was anyone's guess.
