Beforeword: I wanna thank those who gave my story a favorite and "Itsuki Minami1" and "Ddraig the invincible" for the reviews. I'm sorry if I didn't make it clear enough, but Tatseyo is not Saiki Kusuo's child, Kuriko is, she even used the same powers as him. I hope this new chapter will make Tatseyo's blood relations clearer.

Also, to avoid misunderstandings regarding the timeline: This story begins between volumes 8 and 9 (between Season 3 and 4 in the anime) of DxD. Rias's peerage is complete, Loki has been defeated, the match against Sairaorg is going to happen, the enemy now is the hero faction and they are preparing for their trip to Kyoto, that's the context where Tatseyo will arrive at Kuoh Academy.

Comment if you have any suggestions, questions or just want to compliment. Let's go!

Part 1

Well, here I am, Kuoh Academy.

The large campus and tall facilities can be seem even from afar. I had only seem it in the ads, but this place is really big, I hope I won't get lost.

Some time ago it only accepted girls but now it's accepting boys as well, mom said that it was a golden opportunity and father, although disaproval of the idea of sending me to another town, didn't opposed her, he wanted for a long time to have me attend a normal school like he did.

Sorry, I didn't introduce myself, right? My name is Tatseyo Kageyama, son of the great esper Shigeo "Mob" Kageyama and the psychic former hero Tatsumaki "Tornado of Terror".

During my whole life I've been relying on my talent to become more powerful, unlike many espers who had to go through training to control their powers.

Mom and dad know a lot of influent people in the esper community, so for many years I've received lessons from espers not only from Japan but from other parts of the world as well, this is my first time attending a normal school since early kindergarten, where my powers first started to affect my daily life.

Mom and dad are very different, sometimes I even wonder how they got together…

Despite of his powers, dad refuses to use them for personal gain, much to mother's despair. He always taught me that psychic powers are not a toy, nor they make me better than anyone else, and I think he is right. When he was around my age he also hunted demons, evil spirits and youkais, but ever since he got a normal job and mom retired from the hero world, she has been doing most of the exorcism works for the family.

I was born with psychic powers, at a very young age I could already move heavy things with my mind and I never worked hard for almost anything and I don't have any hobbies or activities I'm really engaged into.

'Life is about helping others' - That's what dad always tells me

I want to find a way to make my power useful, I don't know exactly what I want to be, but I want to use this power to make the world a better place somehow. Unlike father, who decided to only use his powers when absolutely necessary and works at a normal job, I want to live a life where I can use my powers, like mom does, but I don't think exorcising youkais and evil spirits is making the most out of it.

I never did any training even to reinforce my abilities, my powers naturally increase as I mature and get more experienced with them, most of what I did was study about the supernatural world, spirits, youkais and the like, besides the regular lessons one would have at school, I've also digged into these studies with the help of other espers.

I also took many jobs to get rid of demons and ghosts, that helped me to get more experienced with my powers.

I can move incredible weights at high speed with my psychokinesis, create almost unbreakable shields, move even things who are miles away from me just by sensing their location, increase to abnormal levels my physical traits (strength,speed,reflexes,etc), freely manipulate energy and the spiritual flow, deconstruct or reassamble matter at molecular levels, and most importantly: My powers let me interact with the spiritual world.

That's one of the most dangerous aspects of an esper's power, we can see and sense the presence of spirits, ghosts, demons and such, we can also fight them with our pshychic powers to send them back to the other world, but that means they can do the same thing to us if we're not careful.

As I walk towards the main entrance, I can already see a group of girls with Kuou Academy's uniform talking and giggling while they make their way school, suddenly, a boy with the male uniform approaches one of them from behind, he lifts her skirt, revealing a blue panty, and runs away

They already do that so early in the morning?

The girl screams, but the boy is already far from her reach, I'm standing just a few feet away from the scene, so she angrily turns towards me, probably to vent of her frustration at me

"Did you saw anything, perve… kyah!"

The eyes of the girl and her friends grow huge when they actually see me

Oh yeah, I did forget to mention but if there's something unordinary about me besides my powers it would be what some would call "an intimidating look"

I have senpaku eyes and an expression that tends to scare people, those who don't know me sometimes think that I'm a deliquent.

"W-w-who are you?"

I give them a smile to calm them, but it doesn't seem to be working

"I'm a new student here at Kuoh academy, I'm looking for my class, could any of you help me?"

She tries to keep a calm look and answers me before walking off with her friends

"Sorry, but we're gonna be late, try talking with a member of the Student Council or something"

And I'm left with my thoughts again... socializing is problematic isn't it?

That's what scared me the most when I heard I was going to attend a normal school. Hiding my powers won't be that hard but making friends here is probably going to be.

I can hear their voices while they distance themselves

"What a scary guy, I thought he was going to hurt us!"

"Did you saw that disparaging smile of his? I was sure we would get bullied by him!"

"He'll be attending the same school as us? Scary! I hope he's not in our class"

It stings, but it can't be helped, I knew this was going to happen when I was told I would be attending a school in a town where no one knows me

I take a deep breath and close my eyes

Controlling my emotions is a really important thing for espers like me, mom and dad, so we don't go berserk and hurt people.

It happens that when extremely strong espers become overwhelmed by some sort of emotion, our powers explode and we can cause a huge ammount of destruction around us. When my father was young, he suppresed his emotions with sheer willpower, but it was ineffective and many times he just exploded and many people were harmed because of it. I am able to control my 100% to an extent by concentrating, at least much better than my father could.

But... I still have problems with controlling my emotions, I'm just a teenager after all, so it can't be helped, I know that's not a good excuse and I have to do better but give me a break!

And, well, I have what I think it might be an achievement: I never had to actually go beyond that.

I know, you must be thinking: "What could be beyond 100%?"

Well, honestly, I don't know, no one knows.

All we know is that when father was in the face of death or when the life of someone he holds dear is threatened, he simply lost reason and something inside of him acted on instinct causing an immense ammount of destruction and chaos.

This is called the "unknow percentage" or "? ? ?%"

Father already reached the "unknow percentage" a few times, and even talked to the "thing" he deemed responsible for it, so they know what it might cause thus make their best to control it, but as for me, I never reached it, but considering my powers are a combination of both mom and dad, it's safe to assume the ammount of destruction could be even greater than his.

It is unknow whether only father can do it, but there were rumours about other strong espers undergoing unusual transformations in the past.

Well, thinking about this now is useless.

I take a deep breath and prepare to get in the school grounds, maybe find other second years who know where the class is…

!

As soon as I start approaching the school's front gate, I feel something terrible

Demonic energy!

I instinctively expand the aura around my body and start looking around

Where is it coming from? Is there a demon nearby? I pass the school gates and make my way to the highschool building

My senses don't tickle for none of the students passing by

Yes, none of them are demons, they are not the issue

It's the school! This whole campus, it all reeks of demonic energy!

I get inside the school grounds and start to go further, the deeper I go the more the energy grows, when I get inside the highschool building I can feel it reached it's peak.

This is not good, should I get out of here? No, if none of the human students noticed it, then it means there is no immediate threat, or maybe they are being brain washed?

Just as I was thinking about this, I sense three demonic presences getting closer

Could it be an attack? At this time of day? I front of everyone?

In this situation, Kuriko's words ring into my mind

'You'll meet a dark devil and from there you'll have two paths to follow'

Right now? Will I meet this devil right here already? And it brought company?

Seriously, the last thing I wanted in my first day was to be forced to use my powers, specially in public, but now it seems I don't have a choice. This school seems to be completely dominated by demonic presence.

I expand my aura and stand in the entrance hall with the stairs right behind me, facing the main door.

I feel the presences getting closer and closer

I lift my hand and prepare to blast the entrance at the first sign of danger

*Step, step, step*

It's getting closer

*Step step*

But then when the door opens

I'm left speechless...

What appears in front of me are three completely human figures

One of them is an absolutely gorgeous crimson haired girl, whose hair waves as she walks

It takes me more than a moment to take my eyes away from her and look at the two companions

A brown haired boy and a blonde haired one

It's them, the demonic presence I felt definitely comes from these three!

The crimson haired beauty seems to be bothered by something, she starts to look around, the blonde boy also seems nervous

She must have felt my energy, I pull my aura back to hide it

After I do that, she makes a troubled face, no surprise, an energy like mine appearing and disapearing from nowhere must have been quite a shock for a demon

But what is going on here? I have to search more

By directing my awareness towards someone I can feel even deep hidden energies

I direct it towards them, and as soon as I start searching...

What's this?

I feel a chill down my spine

One of them has an enormous hidden power!

More than a demon, this is dragon level at least! It's coming from the boy who is caring the girl's bag, could he be the dark devil?

What exactly should I do now? I can't start a fight with these many students around and I also don't know if they are real demons or just regular students being possessed.

A loud voice takes me back to reality

"Kyaaa! Why is Rias onee-sama and Kiba-kun walking with that pervert?"

"I hope idiocy is not contagious!"

"Just die Issei!"

Some students are yelling at one of the guys at the trio

The brown haired kid turns his gaze to the floor, so he must be Issei, he is carrying the bag of the crimson haired girl, whose name apparently is Rias. So the blond boy must be Kiba.

The other two give a troubled smile at the not so subtle comments towards their friend and try to keep chatting like nothing happened.

As they keep walking, I just stare at them...

When I notice, they are already passing right in front of me.

"Hey, is everything alright?"

Issei probably noticed my staring and asked me this with a worried expression, the other boy looks at me confused, but Rias seems suspicious

I can see she's different from the other two, did she notice my aura? What should I tell them?

Well, since I decided not to start a fight here, I might as well just ask what I need...

"Not actually, I'm a new student and I don't know where my class is, are you three in the second year?"

Issei raises his hand

"Me and Kiba are, you can come with us if you want"

Rias and Kiba drop their suspicious expressions and nod their heads

First day and I'm already getting help from demons?

How neat...

Part 2

As we walk through the hallway Rias turns to me and asks

"You must be Tatseyo Kageyama right?"

"Hum?"

So she knows who I am?

"Y-yes, how did you know that?"

"Buchou has ties with the student council, so she knows things like that"

Kiba answers my question with a smile

That seems like a lie, knowing that a new student will arrive is normal, but knowing my name too? That's fishy. Also, did Kiba just called her "Buchou"?

"I am Rias Gremory, I'm a third year, this is Kiba Yuuto and Issei Hyoudou, they are second-years just like you"

"It's a pleasure to meet you all, tell me Rias-senpai, Yuuto-kun just called you Buchou didn't he? Are you the president of something?"

"We are members of the Occult Research club, we search about the paranormal and things like that"

Issei explains

Paranomal? Father told me that in his middle school days there was a club like that in his school, they searched about telepathy and such things, but it was mostly an excuse to laze around, though father also told me they did manage to find someone who could use telepathy in the end...

Wait, does that mean they know what an esper is? And that I am one? I should be careful around them untill I can tell for sure

The one who asks this time is Issei

"So Kageyama-kun, where are you from?"

"Seasoning city"

He and Kiba exchange confused glances while Rias chuckles a little

"Sorry, we never heard about it, that's an unusual name for a city..."

He gives an awkard smile

"It's fine, most people don't know about our town. And if you think the name of the town is weird, you should check the school names over there"

The three chuckle at my remark, that wasn't a joke you know...

As we walk through the hallway I notice that Kiba and Rias are quite popular, almost everyone greets them with a smile and a compliment. Issei on the other hand only receives mean remarks about how he shouldn't be so close to the school's idols.

Geez, even if he's a devil I'm starting to feel sorry for him

And about me? Well, since I'm new everybody greets me, but I can see they are avoiding to look me in eye.

But most importantly, during this whole time I was also trying to sense the presence of anything resembling a "dark devil".

My suspicions were focused on Issei at first, even though I don't know what a "dark devil" is supposed to be like, but now I don't think it's neither of them.

Not that it matters though, a demon is still a demon, wherever they are it's my duty to get rid of them.

As we get closer to our class, Rias and Kiba say their farewell and leave for their classrooms, so I'm on the same class as Issei huh?

As they distance themselves I can tell even more clearer that the energy I've felt before comes from this Issei, the hidden energy within his body is a serious threat. Even if he's not the "dark devil", I must deal with it as soon as I get a chance.

We finaly reach our classroom, in front of the door stands a beautiful silver haired woman that politely greets us

She also reeks of demonic energy…

Really? Another one? What's more, I can feel demonic energy from inside the class as well, that means there's more waiting for me inside

She smiles at us

"Hi Issei-kun, please go inside, the class will start soon"

"Okay sensei, see ya Kageyama-kun"

Issei goes inside the classroom and she turns to me

"So, you must be Tatseyo Kageyama right?"

I look at her from head to toe, she's quite young for a teacher, and I can tell without a doubt that she is a demon.

"Yes, from Seasoning City."

"I am Rossweisse, hope you'll enjoy our school and get along with everyone"

Well, for a demon she's quite charming and polite...

Yeah, as if!

This must be some sort of trick, I gotta keep my guard up!

"Thank you, I'm looking forward to it"

I'll keep my disguise untill I have a better idea about what to do

As I touch the doorknob to get inside the classroom, "sensei" let's out a screech

"Ehhh! I forgot to bring today's assignments!"

I turn around and see a deeply troubled Rossweisse checking inside the case in her hand looking for something that's apparently not there.

"Sorry Kageyama-kun, I'll have to go to the teacher's room for a second, please go in and make yourself comfortable"

She dashes through the corridor before I even get a chance to answer. Is it okay for a teacher to run in the hallways?

I shrug and get inside the classroom.

There's still no teacher around, so the students are at ease, talking with each other, joking, some are even sleeping.

A few of them notice me and start whispering to each other. I glare at them and they lower their heads and advert their gaze, did I scare them?

Well, guess the first thing to do is find a place to sit, I take the seat that's more on the back of the room

Once inside the class, I can see who are the responsibles for the demonic energy I felt outside the classroom...

Well, I can see it, but I can't believe it!

A cute blonde and a beautiful blue haired girl!

Without a doubt the demonic energy comes from them.

And more!

There is also a chestnut haired girl who emmanates a ridiculous ammount of holy aura! I never sensed something like it, not even in priests, what is going on in this school?

Suddenly a conversation catches my attention, Issei seems to be getting scolded by two male students

"ISE! One of my sources told me that he saw you in the shopping district in company of not only Akeno-san but Xenovia-san as well! How come you be so lucky? You son of a bitch!" - Said the one with glasses

"We won't forgive you if you make a move on one of the school's precious gems!" - Said the shaved head one

Issei, visually troubled, replies:

"That's not what you think, we were just shopping for supplies for the club, that's all there is!"

Issei is a womanizer? This guy with a very plain appearance, light brown hair and average face?

Well, maybe even a total regular guy can find love in this school? I hope so, I really could live a happy life here: a girlfriend, college, that would be nice. This town is quite good, but my duty comes first

Yeah, exorcising these demons is a priority

Issei and the two boys seem like they are friends, even though he's a devil and the other two are clearly human.

I don't have many friends and most of them are other espers, we try to hide our powers from normal people and if they find out they either get scared or try to use us for their advantage, it happened once with my father when he was in middle school. That's why I don't show my powers to normal people. But even with my friends who are espers there were not many who I am close with, besides Ayumu.

If it wasn't for her, I probably would have been really lonely

Due to my powers being many times stronger than most espers I was separated from them, some were scared of me and some thought I would be arrogant because of my powers and family. Even creatures classified as A-rank anomalies or Dragon level threats were quite easy for me to handle, other espers praised me for it, but I never worked hard to achieve such power, so it always felt as easy and not very fulfilling

Also, in some missions I had contact with people called "priests" who can also exorcise demons and such, but they need special weapons and artifacts, whereas espers only need to use mind and willpower to do so.

I never liked the priests, and I'm pretty sure the feeling is mutual, you see, priests and the like are the main force when it comes to battling supernatural forces, they come from different religious institutions around the world, but aside from special training and holy equipments they can't compare to a really strong esper, even so we are mostly called in three situations: Local ghosts and spirits when the locals don't want to or can't call the church, when the church doesn't help or when they finally decides to lower their heads and ask for our help, though that rarely happens.

One time I was called to exorcise a demon (who looked more like a monster) that had already killed 12 priests before they decided to ask for help, talk about stuborn.

Rossweisse sensei enters the classroom and everybody sits down, all the boy's faces suddenly light up, no surprise, she's really pretty: long hair, a beautiful face and a well endowed body, she's a feast for anyone who likes mature girls. She clears her throat and starts speaking:

"Sorry for taking so long, before we start today's lecture, I would like you to welcome our new transfer student, Tatseyo Kageyama, please come forward and introduce yourself"

Crap, I forgot about introductions!

I'm really not a good public speaker, so I lift myself from the seat and slowly walk towards the board and write my name on it even slower while I try to think of something to say.

When I look at my classmates there are many who have terrified expressions and some are even whispering to each other. I guess I can't blame them, even if people tell you can't judge a book by it's cover everyone ends up doing it, it's a natural thing.

"I am Tatseyo Kageyama. I am from Seasoning City, but I'm currently living in the 10th district, I like reading, playing video games and music, hope I can get along with everyone"

I just say the first thing on my head and make my way back to my seat, I wasn't really in the mood for thinking it through, but I believe I delivered it well enough.

With that, Rossweisse starts the class, but I can't really focus because I'm thinking about the situation I'm in.

I've never seen demons like these, they don't seem like a possession case but it's the only explanation I can give at the moment. I've already seen demons and evil spirits with human looks, but Issei and the others seem to be living like completely regular humans, even this Rossweisse behaves like a total regular teacher.

I decide to wait untill class is finished, if nothing weird happened untill now then they probably aren't an immediate threat, but I gotta make sure to keep them in surveilance untill I can take them on without any bystanders around.

...

Actually, something else is weird...

There's no malice in their auras

I've faced my fair share of ghosts, youkais, demons, you name it, and all of them had some sort of malicious intent in their presence, a killing instinct if you want to call it that, and the auras I'm sensing have none of it, like they are passive, not a hint of threat at all. Just what is up in here?

Part 3

Class is over, I start packing my materials along with everyone but paying close attention to Issei.

Rossweise already left but I decided to stay and check the other three.

The cute blonde and the beautiful blue haired girl make their way to Issei.

"Ise-san, president Rias said she wanted to see us in the club this afternoon" - says the blonde one

She really is a cutie, thought the blue haired one doesn't fall behind either, are they all over this guy? Well, he really is powerful, I give him that.

"OK, Asia-chan, I'll go with you two, just wait for me to pack" He answers

The chestnut haired girl with twintails approaches the trio and starts talking with Xenovia, as she moves closer I can clearly sense the flow of her holy aura moving along too

Just what is a holy-aura user doing here? Perharps she already took the job of exorcising the school?

When she gets close to them I imagined a thousand situations in my head

"Xenovia, Asia! I heard of a new cafe that opened just down the street, do you want to come with us? You can come with us too Issei!'

Hum? That's it? A coffee invitation?

"Sorry Irina, but Rias needs us at the club today, can we go together another day?"

"We're sorry, but Rias buchou really needs us to prepare for the school festival, so we are very busy right now, sorry!"

Ah, school festival! I've also heard there'll be a trip to Kyoto soon, damn, it seems I have arrived in one of the busiest times of the school year.

Irina makes a sour expression before smiling again

"Don't worry Asia, we can just do it another day then! See you later!"

She waves farewell and leaves with a group of other girls, how can she be so friendly with them?

Well, maybe I was overthinking, maybe she's an exorcist or priestess that just happens to go to the same school as them, with no relatio to what's happening, but for her not to notice Issei's tremendous hidden aura or the demonic energy that's all around this school?

She must be a begginer or she's just very relaxed at school. Or maybe she's ignoring it on purpose?

I think about going after her, but I decide against it, Issei and the others seem like a more urgent subject to deal with right now

As I'm making considerations about what just happened, the blue haired girl, that Irina addressed as Xenovia, turns to Issei

"Issei... sorry about last night, I didn't expected Rias to get so mad, if you want it we can try it again today, I've brought protection this time!"

She says it as she pulls something out of bag, she's holding it so just the three of them can see but upon closer inspection I see it...

A pack of comdons?!

What the actual fuck? Is this even allowed here? Is that their normal behaviour?

The blonde girl who must be the one called Asia, goes bright red and the boy visually disturbed starts crossing his arms and reprehending Xenovia

"Xenovia-san what are you doing? I already told you to not do this in public!"

He's visualy flustered, just what kind of relationship do they have?

After the chaos has subdued, Xenovia went to wait outside while Issei and Asia packed their books

"All done, let's go!"

As they walk out of the classroom, I notice the evil energies distancing themselves as well.

The Occult Research Club, huh? It was suspicious from the beginning, but now it's obvious that it's just a front for demon activity.

This is going to be interesting...
