I was over looking the fleet waiting for our next mission the one of my second in commands captain ace told me that the fleet's hyper drive engines are malfunctioning and sending us to a unknown location as soon as we made the jump I blacked out. I woke up to see we were above earth but it was different. I looked through my people's star maps and saw it was another earth labeled earth-dxd. I read the file further and found information that could help us. I told the fleet to cloak everything even the crew and ordered a cloaked shuttle to bring us to the planet's surface. We land in a location called kuoh masking our presence then we see a little girl running from a man like monster so I drew my cross guard light saber and my spinning cross guard light saber then force pulled the girl behind us and was about to slash the beast when it knocked my weapons out of my hands. The monster then grabbed aqua and was about to eat her then time slowed. I charged straight at the beast then a sky blue and white gauntlet appeared on my right hand. then I punched the beast so hard it exploded into a bunch of particles and where the beast once stood there was a man who smiled at me then said thank you and slowly faded away in particles of light his soul finding peace. I walked up to the girl I saved after checking on aqua and asked her what her name is and she replied.

Isabela: Isabela hyoudo.

I walked her home then she said she wanted to join me and the council said yes making Isabela a official novitan after I gave her a choice between which piece she wanted and she picked warrior (pawn) path giving her access to every path except king. I then hacked into the world wide web and made it so that we are registered as American citizens and transfer students to kuoh so we learn about this world we're stuck on. We then went to the house we bought and made a underground base in it with warp pads to send stuff from the ships to the base. I got kuoh academy uniforms for me and my team then went to sleep after putting a enchanted barrier around the house and the base to keep unwanted guests out.

Time skip.

I was sitting in class until I was called to the ORC building and saw rias gremory who wanted me to join her but I told her that I have my own faction to run. she then tried to convince aqua but aqua said no she was about to try and bribe aqua until she saw my left eye change.

Image mine.

I left with aqua following then issei tried to convince his sister Isabela but she told him that she was in my faction. I was about to walk out until I saw two of these exorcist. Then this kokabiel guy shows up but I blasted him with a energy ball killing him instantly then found a way to get kuroka off the stray devils list and proved her innocence. I was about to leave until.

Xenovia: we heard that in your world god is still alive is that true.

Me: yes.

Xenovia: can we join your faction then.

I agreed and was about to make them my paladins until rias snatched the pieces away.

Me *angered tone*: give those back.

She shook her head and said no then I summoned archaeos infinitos in king mode moving fast and took back the pieces from her.

Me: do that again and there will be consequences.

Issei: don't threaten rias like that!

He punched me while my back was turned then something snapped I finally awoke my dragon form making all the ORC shake in fear.

Image mine.

I was about to blast issei until aqua said don't so I changed back and left with my group.

Time skip.
I was sitting at home trying to hold back my inner hollow then the door bell ringed so I went to answer it and saw a package from my family and in it was books. I was reading and was about to go to bed until aqua came in the room.

Me: hey aqua ready for bed.

Aqua: yeah.

Me and aqua started dating after the gremory incedent and I was about to fall asleep until I heard a call for help.

I flew out of the window with two of my twelve wings then landed to find a girl with black hair and yellow eyes about to dragged off by some rouge hollows.

Blake.

Images not mine.
The rouge hollows.

I stabbed one of the hollows through the head and decapitated the other two. I then helped the girl up and said.

Me: hey are you okay?

Blake: I'm fine and my names Blake.

Me: Kevin, Kevin archaeos novis.

She told me that she had nowhere to go so I let her stay with me and aqua. I made her one of my knights
after she said she wanted to join me and I was about to take us home until rias showed up.

Rias: she is coming with us Kevin.

Me: says who.

Rias: says the fact that she is a nekomata automatically making her part of the underworld.

Me: if that is the case then why were they nearly killed off completely and she is a part of my faction so if you want her you have to go through me.

I deployed archaeos infinitos in paladin mode making it have parts of a shield coming out of the sides and a long broadsword blade coming out above the knuckles on the gauntlet.

Rias: we don't want to fight Kevin we just thought that she would be happy there.

I was about to use my speed to get Blake inside the protective barrier until I heard aqua scream. I looked up and saw a guy holding aqua fly through a magic circle with a picture of a phoenix on it and disappeared.

Me: Aqua!!!!!!

I then unlocked my break through form with my balance breaker armor forming and half of the my hollow mask on my face which changed to have a armor plate on my cheek that goes past my chin and all twelve of my wings came out. The armored part of my wings turned gold and had a blue cross near the talon on each of them while the remained white then the blade like feathers on my wings stayed white and gained glowing sky blue edges.

Me: rias who was that guy who kidnapped my mate!

Rias: riser phenix, why?

Me: because he is going to be a dead bitch real soon.
