Your POV:

I was standing, no scratch that, I was lying on my back, in my mindscape, after a rather "vigorous" training session with Giratina, who was currently in his human form, and looked like he didn't even warmed up yet.

Giratina: I believe this is enough training for now.

"My body agrees with you. Seriously, I still wonder how I'm still alive by now..."

Giratina: Well, this is your mindscape, it's normal for you to not be able to die here.

"About that, I wanted to ask..."

I painfully sat, and designated my surroundings.

"Why does my mindscape looks like this ? It doesn't makes any sense..."

Giratina: For you that is, but this is a reproduction of where I was before meeting you, it's a place called "The Distortion Dealm".

"So this was your home then ?"

Giratina: I would probably call it a prison rather than a "home".

"You were imprisoned here ? What happened ?"

Before he could answer me, I suddenly started to fade away, as I was waking up.

Giratina: This will be a story for another time, you should get ready for school now.

Giratina: and please, when you wake up... Just don't freak out.

"Why would I be freaking out ?"

Giratina: Don't worry about it, I'll see you later.

With that, I finally disappeared from my mindscape.

Giratina's mind: 'And judging by how "They" already managed to locate us, it shouldn't be that long before he learns the truth...'

Back to the real world, still your POV:

I groggily woke up, still half-asleep, but when I tried to get up, I couldn't, as I felt a weight on my chest.

I then spotted a rather large bump under my covers, but as I was still questioning myself, and tried to figure things out, it started to shift, revealing... a naked Akeno ?!!!

At that moment, only one thought crossed my mind, and it was:

'AAAAAAAAAAAAAAAH !!!!!'

Giratina: 'I told you to not freak out...'

'Wait, you knew about that ?! Since when ?!!'

Giratina: 'Well, she showed up literally 30 seconds after you fell asleep, and she was clinging to you this entire time.'

'Why haven't you told me anything about this, if you knew from the beginning ?!'

Giratina: 'First: I wanted you to focus on your training, and second: she looked extremely comfortable, sleeping with you like that.'

'I may be the kind of person that enjoy cuddles, but this is a little too much.'

Akeno finally woke up, and redressed herself, giving me a full view of her body in the process.

Akeno: Go back to bed, you make a perfect pillow~.

My reflexes kicked in, and I pushed her aside, and she hit the ground with a loud "thud".

"Alright, two questions. One: Why are you in my bed, and two: WHY THE HELL ARE YOU NAKED ?!!"

She got up from the floor, and approached me, a little too much for comfort, in fact.

Akeno: Well, to answer your first question, Rias asked me to look after you, but when I saw you sleeping so peacefully, I couldn't resist, and next, I always sleep naked.

'That damn tomato, when will she learn to mind her own business ?'

Akeno: If that can reassure you, we didn't do anything.

I checked, and breathed a sigh of relief at the sight of my pajamas, still on.

Akeno: But you know, I wouldn't mind being more "private" with you~.

"J...Just get up already, we're gonna be late for school."

Timeskip after breakfast:

We were now walking to school, and Akeno was close to me, very close.

In fact, she just wrapped herself around my arm, and refused to let go of it.

"So mind telling me why you're clinging to me like that ?"

Akeno: I already told you, Rias asked me to watch after you, in case one of those fallen angels try to murder you again.

"How many times do I need to tell her that I'm NOT gonna join her peerage ?! And I'm plenty able to defend myself, thank you very much."

Akeno: Don't be that insensitive, she really cares about you, you know.

"She only cares about my powers, to her, I was nothing but a "worthless human" before I get them."

Halfway to school, we bumped into Rias and Issei, walking together, looks like the pervert has the same surprise as me when he woke up this morning.

Issei: Yo Y/n, so, you too...

"If you say another word about this, I'll be forced to punch you, Issei." I said, covering my hand in purple aura.

The pervert was scared shitless, and kept his mouth shut for the rest of the path.

Once we passed the school gates, we immediately grabbed all the attention of everyone that was present.

RG1: Is that Akeno walking with the knight ?

RG2: No way, are they dating ?!

RB: Dammit, I'd wish to be in his place right now...

RG3: Hey, why are Rias and the pervert holding hands ?

We finally reached our class, and Akeno let go of my arm.

Rias: We'll see you after classes, I'll send someone to fetch you later.

"I already told you to stop order me around..."

She just ignored me, and Akeno blew me a kiss, as I just waved back.

Issei and I entered the classroom and-

???: YOU BASTARDS !!

I instinctively dodged a fist that was going for my face, and put my attacker in a armlock.

Baldy: Ow ow OW !!

It was the two remaining members of the perverted trio who tried to ambush us, and half-succeeded, as they got Issei.

Glasses: Why were you walking with the goddesses, you traitors ?!

I couldn't care less about that, so I just released the baldy, and sat down at my desk, waiting for the day to end, while occasionally scaring off some guys who tried to beat me up for apparently "dating" Akeno.

The day ended, and we were just waiting for that "someone" to fetch us.

I already had an idea of who is going to show up, and my hunch confirmed itself when I heard some high-pitched screams coming from the hallway.

'Looks like the prince is about to show up.'

And right in cue, Kiba entered the classroom, followed closely by his fangirls.

Kiba: Are Issei and Y/n here ? I'm looking for them.

"Don't bother asking them, Kiba, we're right here."

Kiba: Good, Rias asked me to retrieve you to the ORC clubroom.

"Go ahead, pretty boy, I already know ya way."

Giratina: 'You need to stay away from your computer.'

'Shut up that one's hilarious.'

The three of us left the classroom, with half the girls fantasizing about me and Kiba, while the other half was complaining about Issei.

Giratina: 'You were right, they are annoying;'

'Told you so...'

Soon enough, we reached the clubroom, and it hasn't changed that much since last time, the only difference was Akeno, who immediately walked to me, and that white-haired girl, eating some sweets on a couch.

Akeno: So you're here, I was worried that you would decline the invitation.

"She never really gave me a choice in the first place..."

We suddenly heard running water from a door, on the other side of the room, and of course, Issei's reaction was predictable.

Issei: You guys have a shower here ?!

This sentence earned him a bump on the head, making him very "intimate" with the wall.

"Those perverted antics of you will get you into trouble one day, Issei."

What surprised me next was when the little girl walked to me, and handed me a chocolate bar.

Koneko: The name's Koneko Toujou, let's be friends.

She had an emotionless voice, and for some reasons, she reminded me of a cat.

I sat down on one of the couch, with Akeno sitting by my side, and started to eat the bar.

Akeno: Well, this is a first, I've never seen Koneko sharing her sweets with anyone before, she likes you.

"For what I understood, we both hate perverts, so I don't find it that surprising after all."

The water stopped, and soon, Rias came out of the bathroom in her uniform, drying her hair.

Rias: I'm sorry for making you wait, I didn't had time to shower at your house, Issei.

Said pervert, who managed to disencrust himself from the wall, looked down in regrets.

Issei: I DID proposed you to...

Rias: Now, Issei, I believe you have several questions, but before, let me ask you something: Do you believe in the supernatural ?

Issei: Not really, why are you asking ?

She then revealed her wings, along with Akeno, Koneko and Kiba.

Timeskip because everyone know what happened (and also because I don't know how to write it down...)

To say that Issei was shocked would be an understatement, he just froze stiff after those revelations.

Me, on the other hand, I was calmly drinking some tea Akeno made. I may not be a big fan of tea, but I'm forced to admit, it actually tastes really good.

Issei: So let me get this straight: That girl I dated was real and a fallen angel, and she erased everyone's memories about her after she killed me, what she did because I possess what's called a "Sacred Gear" ?

Rias: that's correct.

Issei: And the reason that I'm still alive, is because you reincarnated me as a devil, since you and everyone in this club are actually devils.

Rias: Exactly.

Issei: But then, what about Y/n ? He died that night too, right ? So does that mean you reincarnated him too ?

Rias: In fact-

*SHACLKING*

Before Rias could really answer his questions, everyone in the room heard a loud noise of broken dish.

They all turned toward me, as I was gripping what remained of my now-empty cup of tea.

I tried to remain as calm as possible, but I was literally two inches away from bursting out.

"No Issei, she didn't reincarnated me, I'm still a human." I said, gritting my teeth.

Rias: That is why I asked you to come over. You're claiming you're still human, but you managed to defeat a fallen angel, and you almost killed him.

Rias: You also need to give me your answer about joining my peerage.

"My answer hasn't changed, Gremory, I refuse to be your servant."

Issei: Come on Y/n, you could get so many things being a devil, like a longer life or more power !

Rias: He's not wrong you know.

"A longer lifespan doesn't appeal me, and I already have more than enough power."

Giratina: 'Aww, thank you.'

Rias: Please Y/n, I ask you to reconsider-

I couldn't hold it any longer, and burst in controlled anger.

"I already told you this numerous times, Gremory, I would never throw away my humanity for you, even if I was promised eternal youth and power. You said I was nothing but a "worthless human" before I got these powers, and now that I have them, you suddenly care ? You disgust me, you're just a power hungry bitch !!"

I released a large amount of aura, and my wings sprouted out of my back, flaring wildly.

Everyone in the room took a step back, and everyone beside Issei assumed a battle stance, preparing themselves for battle.

Giratina: 'Please calm down, now's not the time to start a direct conflict with the Gremory household.'

I slowly breathed in and out, and managed to discard my aura, and I sat back on the couch, under the cautious glares of all of the ORC members.

"Listen here, I'm sorry about my sudden outburst, but I still mean what I said, I will NOT join you."

Still unsure of what to do, Rias slowly regained her composure.

Rias: A...anyway, Issei, now that you're part of my peerage, you'll need to deliver those flyers. She said, handing one entire bag of those, and they looked quite similar to the one Issei got in his date.

The pervert didn't seem overjoyed with that.

"Not what you expected by being a devil Issei ?"

Issei: It doesn't matter, with my new lifespan and powers, I'll finally be able to become-

"Go on, finish that sentence, I dare you..."

Issei: N...Nevermind, I'll be going now.

With that, he left the clubroom to deliver those flyers, and I prepared to leave too.

"I'm heading home now, and Gremory, don't try to follow me, or you'll regret it."

I finally got out of here, and headed back home, but on the way, I couldn't shake off the feeling that I was being followed, but not by a devil, or even anything that I've met before.

I reached my house, and sat down on my couch, still feeling those powers approaching me, but for some reason, they felt... Familiar, almost reassuring.

I was lost in my thought, and I failed to notice they were that close already, but I realized it when they suddenly knocked on my door.

"Should I answer ? They didn't feel harmful but they're definitely strong."

Giratina: 'You can open the door, I know them, they mean no ill.'

"Alright then"

I opened the door, and spotted six figures eyeing me from head to toes.

The taller one suddenly extended its hand toward me, and spoke:

???1: Good evening, host of Giratina, my name is Arceus, and I believe we need to talk.

Telling Rias to fuck off. It never gets old.
