Timeskip an hour of explaining from both sides no one POV

Rias: "so let me get this straight" Rias is sitting on one of the sofas while Jason is sitting on the opposite sofa "your an alien" Jason nods "and your not from this dimension" he nods again "and you have been trained by one of the strongest angels in your dimension" nods "and you have the strength to fight the gods of your dimension?"

Jason: "well not in my base form but I can transform to get that strong" he loosens his tail then rewraps it "honestly in my base I'm stronger than anyone in my dimension except for the angels and the gods of destruction" Rias and the others look shocked except Koneko who looks amazed

Rias stands up and smiles

Rias: "why don't we test your strength. My peerage against you. What do you say?" Jason stands up and stretches

Jason: "sure" he removes his chest piece and drops it smashing into the floor and breaking it from the weight "sorry forgot I have weighted armor on" Rias is shocked from how casually he removed it with no strain

Koneko POV

Me: "so that's why he was so heavy"

Timeskip to outside Jason POV

I stretch without the weight of my armor while Rias and her peerage are on the opposite side of me

Me: "I'm going to hold back okay? I don't want to hurt anyone" they get ready as I get into my stance

Kiba attacks first by launching at me without a weapon and I jump back as he makes a sword and slams it where I was standing and makes another one swinging very fast making me take him seriously as he keeps swinging and I grab his blade and punch his stomach and spin kick him away as I dodge a bolt of lightning from Akeno

Akeno: "aww I missed" I look at her as she has a blush and she keeps launching lightning at me making me dodge and she finally hits me and it fucking hurts "got him" I launch out of the lightning and aim a punch at her only to get hit by some red energy sending me skidding across the ground and I get up hurt from what hit me

Me: "okay what the fuck was that?" I brush the dirt off me as I think to myself why the fuck couldn't I sense that

Rias: "we use magic. Don't you use it to do what you do?" I shake my head as I get back into my fighting stance

Me: "I use ki not magic. This is gonna be difficult" I launch forward and dodge a blast from Rias and send a punch only to get it caught by Koneko and I catch a fist from her making a crater form around us until I sweep her legs out from under her and throw her away and catch a sword from Kiba only to get blasted from Akenos lightning as Koneko shoulder charges me sending me flying and I stop myself in the air and look just in time to see a giant blast of lightning,  a giant blast of red energy, a wave of swords, and a giant boulder coming at me and I react by roaring and powering up

No one POV

Jason roars and powers up destroying the attacks and bathing the area in a yellow glow as the smoke clears showing Jason in super saiyan form

Jason: "now I'm serious" he disappears and reappears punching Kiba in the stomach making him spit up blood and punching him into the ground and leans back dodging an attack from Rias and smacking Akenos lightning away and jumps back dodging Konekos punch making a crater where she hit and spin kicking her but she blocks and grabs his leg but Jason twists and kicks her away and is bombarded by Rias and Akeno

Akeno: "can we even beat him as he is now?" Jason suddenly lunges out of the bombardment attack and hits the back of her neck knocking her out and gently setting her down before launching at Rias and she sends attack after attack holding him back by her attacks

Rias: "how are you so strong?" He blasts through her attack and is in her face

Jason: "because I'm Batman" he punches her into the ground knocking her our and gets a boulder thrown at him shattering when it hits him and he looks to see Koneko breathing hard with some of her clothing torn "stand down Koneko. I don't want to hurt you" she runs at him and throws a punch and he catches it making a shockwave from the impact and she throws another punch and he catches her other fist and they stand there as she tries to break out of his grip

Jason POV

We stare at each other as she has stopped struggling and I notice she has some cute cat hair clips in her hair

Me: "can you please explain to me what happened this morning?" She loses her monotone look and blushes a little "please talk to me" I let go of her fists as I power down to base and she looks away from me

She doesn't say anything at first but she looks at me blushing hard

Koneko: "when I first met you your eyes had the look of someone who's been through some crap. I thought maybe I was imagining it until I saw you having a nightmare" I crouch to her level as best as I could with my height

Me: "can I know why you have cat ears?" She shakes her head "okay then" I look over to her friends "we should get them back to the orc building" she nods as we grab her friends and fly back to the orc building

Timeskip to the group waking up

I'm reading a book I have in my requip pocket dimension when Rias groans and sits up and sees me with Koneko on my lap

Me: "have a nice nap Gremory?" I turn the page and continue reading as Rias groans in pain

Rias: "what happened?" She gets up as I toss her a senzu bean "what's this?"

Me: "to answer your first question I kicked your peerages ass and for your second question it's a senzu bean. Eat it and it'll restore you" she looks at me skeptically "hey Koneko had one and she's fine" Koneko waves as Rias eats the bean and is surprised

Rias: "wow. It's almost like Pheonix tears" I give her a wtf face "it's a healing thing like that bean" I toss her two more

Me: "give those to Akeno and Kiba. We put them in the spare bedroom" Rias leaves and Koneko finishes her chocolate so I use requip and hand her a candy bar I've been saving "here. I've been saving this for something but you can have it" she blushes a bit as she takes it and she thanks me as I continue to read my book

Koneko: "can you train me? To get stronger?" I pet her head making her blush and I put my book down

Me: "of course I'll train you. Your strong"

Rias comes in panicked with Akeno and Kiba

Rias: "John you have to-" a red teleportation circle appears in the middle of the room and a man with long red hair and armor appears

???: "Rias we need to talk"
