Kuoh Academy, was a prestigious place of learning for brilliant young minds from Kuoh Town that recently had undergone changes regarding the rules of its student admission, namely the acceptance of male applicants as potential new students. The new regulation itself had only been effective for a year, so there were still some rough developments with the dynamic between sheltered female students and the new male students. The prime example of this was the existence of the dreaded "The Perverted Trio" who were seemingly on a never-ending quest to get themselves arrested for sexual harassment. Nevertheless, the student council president had been successfully keeping the order.

But secretly, the school was also the headquarters of two young heiresses from noble families of Devilkind. One of them was the young heiress of the renowned Gremory family named Rias Gremory, gained its fame with their signature ability that was only present in the blood of said family, the Power of Destruction. Not only that, one of the current Four Great Satans and holder of the title "Lucifer", was also a member of Gremory family. To mask her activities as the King of her peerage from the regular students' eyes, she created Occult Research Room together with her peerage and acted as its President.

As for the other one, Sona Sitri was the heiress of the prestigious Sitri Clan, known for their deep affinity with water-based spells and the abundance of natural environment within their territories. One of its members was also the holder of the title "Leviathan", which was also one of the Four Great Satans along with "Lucifer". Strict, smart and studious, she was truly the ideal figure of a student council president.

It had been almost a month since Hyoudou Issei lost his old life and "reborn" as the newest member of Rias Gremory's peerage. While currently being deemed as the weakest devil in the school, it was also revealed that he was the current bearer of one of the 13 Longinus Sacred Gears, Boosted Gear. It housed the soul of one of the Two Heavenly Dragons, Ddraig the Red Dragon Emperor, much to the delight of one red-haired heiress. While his existence briefly created a slight tension between two heiresses (which some may pass it off as mere petty rivalry), it was quickly resolved when the black-haired heiress had deemed Issei to be incompatible with her peerage.

Unknown to everyone, another piece was about to enter the board and twist the predetermined gears of fate.

"GYAAAAAAAHHH !"

"You're truly disgusting, Issei-senpai."

Shortly after school hour was over, members of the ORC often gathered in their club room whether to pass the flow of time or fulfilling their daily tasks as a member of Rias's peerage. Issei, known as the avatar of lust itself, wouldn't miss his chance to laid his eyes on any female's body part that wasn't covered in silky fabric of their uniform. Rias, being the exhibitionist she was, didn't really care about her surroundings when she stripped her clothes off to take a bath in the clubroom's shower. At this golden opportunity, the brown-haired boy spared no time to attune himself to be one with nature and directed his eyes to gaze upon the bountiful gift from God (or Satan ?) himself. He had all the desire and intention to record this rare glimpse of the Eden itself to serve as his material for his daily "research".

Or that was what should be happening if not for the presence of one white-haired nekomata.

"B-but Koneko-chan, this is a rare opportu- GYAAAAAHHH !"

"No."

He was suffering from the iron grip of the cute nekomata on his arms. The rest of the peerages silently watched the occurrence while doing their own things.

"Issei-kun is surely has a strong willpower, I can give him that. It's useful trait on any battle situation." The resident school prince Yuuto Kiba, who was also the sole 'Knight' of Rias's peerage, only shook his head in amusement at his newest teammate's antics.

"Or perhaps secretly he's enjoyed being dominated by a cute loli ? Ara ara, I wonder if he has a big-breasted onee-san on his list." Vice President of the club, Himejima Akeno was brewing the tea and preparing a set of cupcakes. Polite and well-mannered, she seemed to be a proper ojou-sama like her President. Alas, not many people knew the darker side of her personality, namely the unquenchable desire to perform sexual domination, inflicting both pain and pleasure on anyone she found interesting regardless of gender.

"At the very least, the club is more lively with him around. In time, I'm sure he will be the ace player of our peerage. *sigh* if only he would also put the same amount of effort on training and studying his own power..."

"If you will allow me Buchou, I can be his teacher to help him control his power. His ability to boost magical powers would be rather wasteful if he doesn't have any prowess to channel it."

"Of course Akeno, feel free to do anything you want."

"Ufufu, then prepare yourself Issei-kun. Don't worry, I'll make our private session as... stimulating as possible."

"Uuuoooghh ! What is this incredible feeling of fear and excitement welling together in my body !? And as for your question, gladly Akeno-sama ! Please guide me through with your expert hand !"

"Ufufufu~ this would be delightful~"

Such was the normal occurrence between members of the club. Things went out as usual and it should be a few more hours before they concluded the gathering.

If not for a sudden ominous presence that struck the core of every single person within the room.

Rias could felt her body went rigid and ached for a few seconds before it receded. She instantly looked at the faces from her peerage and she realized that she was not the only one who felt it. Koneko curled her body in fright before forcing herself to stood in her fighting stance and clenched her fists, Kiba unconsciously summoned one of his swords and frantically scanned his surroundings, Issei looked like a person who was just being pranked and Akeno built her magical energy and readying herself to cast her spells. While the ominous feeling was already subsided, they wouldn't let their guard down just yet. And of course, Issei was the first one to blurt out his mind.

"H-holy shit ! What the hell was that !?"

"I-I'm not sure, I never feel anything like it before. Akeno, do you have any idea what just happened to us ?"

"No. That presence, whatever it was, managed to broke one of the barriers I placed around the school."

"We need to investigate it. Akeno, come with me. Koneko, Issei and Kiba, search the school grounds and try to find out if there's anything unusual around."

"Yes, Buchou !" The three younger students answered in affirmation before went out from the room while Rias and Akeno made their way to the student council's room.

"Kaichou, do you feel that ?"

"Yes. That presence... Tsubaki, the barrier ?"

"Destroyed. At least one of them."

While they pondered what to do in response, they could hear the sound of a knocked door.

"It's me, Sona."

"Come in."

The door revealed a tense expression from the face of the heiress of Gremory. Following behind her was her Queen, Akeno with a similar expression.

"I assume that both of you also feel the presence ?"

"Yes. One of Akeno's barriers were also destroyed. Tsubaki-san ?"

"Yes, it happens on mine as well although not all of them."

"A trespasser, huh ? Rias, do you think it's the work of those Fallen Angels that have been trying to kill Issei ?"

"I'm not sure... a few days ago I did meet yet another Fallen Angels, presumably the colleagues of Issei's killer. While they are quite strong, none of their presence made me felt dreadful like this."

"Hmm... I assume your peerage already start searching for the trespasser ?" Rias only nodded in reply before Sona decided her next course of action.

"Tsubaki, contact Saji and the rest to come back to school and alert them of the possibility of an ambush from Fallen Angels. I'll go with Rias to search the cause of this disturbance. When they arrive, contact me as soon as possible."

"Yes, Kaichou."

"Then let's not waste any more time, Rias. Honestly speaking I have a bad feeling about this."

"It's only been a few seconds and you already alerted the entire school of your presence. As expected of you, human."

"WHY DIDN'T YOU TELL ME THAT THIS SCHOOL WOULD HAVE A MAGIC BARRIER !?"

"I see no reason why we shouldn't just break it and make ourselves known. You know that sooner or later we would meet these people anyway. Better get rid of that unnecessary waiting around like a clueless idiot and just confront them directly."

"Please just for few seconds, listen to your own words. You'll make us look like the bad guys here. It will bring nothing but trouble to Katase-san as well !"

"Calm yourself, I'll handle the talking for you."

"Uugh..."

The unlucky Kamijou and his ever-present goddess companion arrived at the gates of Kuoh. Misfortune was doing its regular job of making his life as hard as ever. The moment he touched the school's gate, a sound of broken glass rang throughout the air. His face immediately paled at the possible consequences of his carelessness.

"Kamijou-kuun !" He could feel the voice of his first friend in this world rang through his eardrum. From his view, he could see the sight of swaying peach-colored hair heading toward him. Behind her, he could also see another girl was walking behind her.

"O-oh hello, Katase-san." She wore a kendo hakama and adorned with a shinai sheathed on her waist. The other girl also wore the same outfit except without her shinai.

"I'm sorry for troubling you, I didn't mean it."

"It's alright Katase-san, I'm glad I could come here."

"Eh ? Why's that ?"

"I never saw you with a Kendo uniform before, and it looks quite good on you, surprisingly." Kamijou grinned on her, although in reality he unintentionally blurted out the first thing that popped up in his mind because he was panicking, still thinking on what his right hand just did a few minutes ago.

"Fweh !?" Poor girl had her cheeks set on fire by the unlucky boy, who didn't even realized what he had just done.

"Oh ho~ so this is the boy that captured the heart of our Kata-chan. I have to say that you're not actually that bad in the looks department. Could use some polish though."

"Murayama-chan !"

Kamijou was unsure how he should react to the new girl's comment about him.

"Ah, where are my manners, the name's Murayama. And you must be Kamijou-kun, right ? Kata-chan already told me about you."

"O-oh is that so ? Then nice to meet you, Murayama-san."

"Kamijou-kun, since you've come all the way here, why don't you join the two of us for a light afternoon snack ? The cakes on our cafeteria are quite the delicacy, you know."

"Is... that even allowed ? I'm not exactly a student of this school."

"Don't sweat it, the school hour is long over and as long as you don't make any ruckus then you'll be just fine."

"(Accept her offer human.)" Hiding in his hoodie's head cover, Othinus whispered into Kamijou's ear and tried to convince him even further to continue their way inside the school.

"S-sure if that's okay with Katase-san."

"Of course I would be glad- I-I mean WE would be glad to have your company !" Katase answered him with a bit too much vigor, much to the amusement of her long-haired friend."

"Then let's be on our way. We only have an hour left before it closes." The three individuals (plus a certain hidden goddess) made their way to the school's cafeteria, and while Kamijou hadn't noticed it, the one-eyed goddess silently stared on the visible bushes near the eastern building.

"That guy... something feels wrong about him. But he's only a human, so how is this even possible ?" Behind the bushes, the blonde-haired prince of Kuoh Academy cautiously watched the exchanges between some members of the kendo club and that spiky-haired boy. He didn't understand why he felt heavy goosebumps just by looking at him.

Especially his right hand. He didn't know what's happening, but he could feel the absolute terror radiated from that hand. But even if devil such as him was frightened by it, then how come the two normal girls that are speaking with him feel nothing from it ? Was it only affecting the Devilkind ? Then did that mean he's an exorcist ?

Seeing the three individuals left the gate area, he dialed his phone to a certain number.

"It's... really good. As expected of a school for rich ojou-sama." Kamijou ate the chocolate sponge cake in delight, while secretly passing bits of the cuts to the goddess sitting in his hood.

"Isn't it ? We're actually quite lucky that they still have some of these."

"Geh !"

"Hm ? What's wrong Kamijou-kun ?"

"N-nothing ! I-I... just think that it must be quite nice being a student in this school, with all these 5 star-quality delicacies. Ahaha..."

"Mmh sure it has it's own perks but there are quite a number of annoyances as well. Especially those three idiots."

"Three idiots ?" Kamijou knew that she was obviously talking about other people, but for some reason he couldn't help but feel stabbed by her words.

"Yes ! Three pitiful boys who are constantly trying to peek on every living and breathing female in this school. It's honestly a pure miracle that they are still allowed to attend this school."

"So Katase-san, are you also one of their victims ?"

"Me and Murayama, sadly *sigh*. No matter how many times we beat them up, it seems to only make them grow even bolder."

So there are three Aogami in this school. I don't know if I'm okay with it.

"So Kamijou-kun, tell me about yourself. Kata-chan only told me that you saved her from a bunch of alley thugs, but she barely let out anything beyond that."

"Eh ? There's nothing interesting about me. I'm just a normal high school boy you can find anywhere."

"You know, there's nothing normal about a starved young man who punched the lights out of potential sex offender and letting himself hurt even more just so he can save a stranger."

"G-geh... you're quite a pessimist aren't you, Murayama-san ? I'm sure there are some nice people out there who would also do the same thing."

"Probably, but I still would like to hear more about you so don't try to deflect the question any further." A devilish grin formed on her beautiful face. Kamijou gulped before he thought on his options.

"Murayama-chan, don't force him if he didn't want to tell it. It's rude, you know."

"Eeeh~ ? I just want to know what kind of person that saved my cute Kata-chan. If he's truly as good as you told me, then I can rest assure that I can leave you in good hand."

"W-WHAT'S THAT SUPPOSED TO MEAN !?" It seems Murayama was quite the devil, thought Kamijou. She was laughing uncontrollably while his poor friend tried her damndest not to faint on the spot. Kamijou could only let out an awkward laugh before leaning his head slightly backward.

("Othinus, are you sure that she's not a devil ?")

("While she certainly has the quality of one, she's just a normal human. Though probably I should've let you know earlier, but...") She rolled her lone eye toward a particular spot a few meters behind him.

("One of them has been watching us from the moment we entered the school ground. This has become quite...troublesome")

His face contorted in confusion before he realized the severity of his situation. A devil. Had found him. With his new friends.

("Othinus, you don't think that they're gonna- ")

("While it's a plausible scenario, I don't think disposing students from their own schools would do any good for them. Tampering their memories would be the only ideal action for them.")

("I still don't like that option. They have no right in meddling with other people's memories, even if it's for their own safety.")

Kamijou sat in silence and weighing his only option. Katase and Murayama who had been arguing with each other realized his lack of voice and looked on him.

("Then I'm sure right now you know what to do, human.")

"Koneko, what's the status ?"

"Clear, Kiba-senpai. He's already heading to the eastern building."

"Is he with the other two students ?"

"No. I'm not sure why but I think he knows we've been tailing him for some time."

"Is that so. I'll go alert President and Kaichou right now. Koneko, you know what to do."

"I understand, Kiba-senpai."

Kamijou had gone with the classic excuse of going to the toilet. Luckily he managed to convince Katase to stay with Murayama as he assured her that he's not that hopeless in finding his destination.

As he walked through the long hallway, his honed battle instinct kicked in and snapped his head to the left direction.

"Human, duck !"

He obeyed her shout and rapidly dropped his upper body down to the floor. He looked up as he saw a lithe, white-haired girl launched an unsuccessful dropkick that passed right above his head.

"W-what !?"

"Stay still."

"!?" The ominous words from the little girl's mouth alerted his senses to the highest degree. He knew that this girl could be a devil, and that's why he would only use his left arm for the time being. It looks like I have no choice here, such misfortune.

"Human, you realize that now you don't have to fight alone anymore, right ?"

"...Eh ?"

"So Koneko is engaging him right now ?"

"Yes, the culprit is just one person. Although we should hurry Buchou, I'm not comfortable leaving Koneko-chan alone fighting with him."

"...Yes, we should."

Not long after Kiba managed to meet with his President and also the Student Council President, they went together to the eastern building.

"And Issei ?"

"Already on his way to Koneko as well, Buchou."

"Right."

As they arrived at the scene, they saw Koneko stared on the suspect with a cautious glare. Rias noticed a bit of shredded cotton and ash dirt on her uniform.

"Koneko ! Are you alright ?!"

"Buchou... yes I'm fine. But be careful, something's not right."

"Eh ?"

She observed on the suspect in question, a normal looking spiky-haired boy with an unknown black-coloured school uniform and a white hoodie underneath it. All in all, he looked like a normal high school boy if not for the strange figure that was standing on his right shoulder.

A woman, with extremely tiny figure and a rather revealing outfit. On her head rested a sizable witch hat and an eyepatch covered her right eye. She stared at her with a cold yet calculating gaze, as if she could judge her entire worth only by looking at her.

"Eh ? Buchou, that...tiny woman. I didn't see her with the boy before."

She turned her sight on the boy again, but this time she could feel the same dreadful feeling that she and her peerage had felt before in their clubroom.

His right hand.

Kiba was right, she could feel a similar feeling whenever she sensed the holy energy used by church exorcists, the only difference being that whatever accursed power from the right hand was more potent and possibly even more lethal. She didn't understand, he wasn't a Fallen Angel and certainly not a Devil. An Angel ? No, it's even more ridiculous.

A human with a Sacred Gear. It's the only possible answer, although I have no idea what it is. Rias finally sorted her thoughts and inhaled a deep breath before speaking to the confused-looking boy.

"Who are you ? What's your business in the territory of Gremory and Sitri ? Depends on your answer, we might have to force our hand to kill you."

However, the boy wasn't the one who answered her question.

"Hoo, entertain me then; What will you do, descendant of Gremory ? Unleashing your bloodline's petty fireworks on us ?" The one-eyed witch purposely elicited an arrogant smirk on her face.

"OTHINUS !" The boy paled in response to his partner's obvious provocation.

"You dare insult my family, witch ?"

"And why not ? That little girl attacked my partner without any warning. It's only proper that we return the favor."

"After you destroyed the barrier of our school ? That should be good enough of a reason."

"It's not our fault that such a pathetic barrier could be so easily destroyed only with a mere touch."

"You... insolent bit-"

"Alright Rias, stop." Seeing Rias being obviously baited by the tiny one-eyed witch, Sona decided to take over.

"And you can stop right now miss one-eyed witch. State your business before I'll remove you by force."

The witch looked on her way with the not-so-obvious interest in her face. The two cold beauties tried to gauge each other, observed every detail they could find and exploit in choking silence before the witch sported yet another smirk.

"You're descendant of the Sitri Clan."

"...You're right. I have to say it's rather intriguing for an unknown magician like you to be able to tell our identity just by the looks."

"And your energy signature, type of mana and signs from your demonic energy only I could distinguish. They told me enough."

"That's... a rather useful ability you have miss witch. May I have the honor of knowing the name of a prodigious magician such as yourself ?"

"...Othinus. a pleasure to make your acquaintance, young Sitri." Oblivious to all but the witch herself, Sona's eyebrows twitched when she heard the name. O-thinus ?... interesting, very interesting indeed.

"The pleasure is mine. And regarding my earlier question, what are you and your partner doing within our territory ?"

"It's a long story." Said the goddess disinterestedly while observing the rest of the people that came with the two heiresses. That little girl and the black-haired bimbo are quite interesting, a reincarnated Nekomata and... Fallen Angel ? Hm, apparently the red-haired princess has quite an eye for hidden talents.

"We have time and place. You can explain yourself at the student council office. Would you want to join as well, Rias ?"

"I think I'll pass. I'm not in the mood to-"

"SO YOU'RE THE CREEPY INTRUDER ! TAKE THIS !" Out of nowhere the last person to arrive, Hyoudou Issei let out a war cry and thrust his dragonic arm toward the spiky-haired boy's face.

"No, Issei wai-"

Kamijou saw the incoming fist and instinctively raised his right arm and collided with the scaly arm.

That day, a thunderous roar of a beast rang throughout the land and skies of Kuoh Town.
