This chapter is a little too short for my liking but this is because I'm planning to do something big.

Chapter 2: The Blue Swordswoman

-With Xenovia Quarta-

It is certainly not a good day to be Xenovia Quarta. The day did start normally when she and a team of exorcists arrived in Romania. It took two hours of hunting for the situation to go FUBAR, especially when she heard that the current Sekiryuutei is running around killing vampires while escorting a small vampire, most likely a dhampir if the vampires are trying to kill him. That in itself doesn't involve her but due to Sekiryuutei's sudden appearance and the strangely alert condition of the vampires, what should've been an easy hunting of rogue vampires and stray devils had turned into a major clusterfuck. Xenovia was separated from the exorcist team when her long hair got caught on a closing door and she got left behind. Now she's lost and surrounded by vampires from all side.

'I should cut my hair shorter if I ever survive this.'

Xenovia thought.

Xenovia was about to pull out her trump card when something strange happen. A portal opens up over her and her enemies. Two people came out from the portal and fell onto the floor before the portal closes.

"Oomph."

"Kyaa."

"Gha!"

The boy yelped in pain when the girl landed on him, hard.

"I'm sorry!"

"Ugh, don't mention it."

Both the boy and the girl got up while the two sides are still surprised by their sudden appearance.

"That's the girl dhampir brat! Men, change of plan, ignore the exorcist and get the girl!"

One of the vampires yelled. That immediately got the boy's attention.

"Ohh bugger. We escaped one problem only to land on another."

The boy complained but is otherwise unconcerned that he is surrounded by over two dozen vampires.

"Guess I have no choice."

Xenovia almost gasped when the boy took out six crosses and slid them between his fingers. Holy artifacts are as deadly to vampires as they are to devils but Xenovia had never seen someone fighting using crosses, at least, not at that size and form.

Her eyes almost jump out from their sockets when blades appear from the crosses. Those are no ordinary crosses and the blades are definitely infused with very powerful light element. They are at least equal to a low to mid-tier holy sword in power. The surprise doesn't stop there as the boy launched many of those swords at the vampires with blinding speed. In the blink of an eye, the vampires are all dead.

-Noire pov-

I honestly curse my luck. Using my still unstable and faulty Kaleidoscope to escape might not be the best idea I ever had. Now I land myself and my charge in the middle of a conflict between an exorcist and a group of vampires. Now let's see what's on my checklist. Infiltrate the vampire city? Check. Rescuing the vampire chick? Check. Escape? That will be the problem. Why is it always the escape? Getting to the center of Einnashe is simple but when it comes to escaping we almost got ourselves killed.

Now we have an exorcist. Just like the dhampir girl she's also a cutie… and she's the same age as me. Well not surprising. The talented ones got to become executor in an even younger age. I started Executor training when I was seven and finished when I was eleven. Apostle hunting for two years and now here I am. I'm even considered by Ciel-senpai to become the eighth member of the Burial Agency.

"Ohh bugger… guess I have no choice."

I love using black keys against these guys. They have never fought against someone using Black Keys and are too arrogant for their own good. At least Magi and Dead Apostles are powerful in their own right and the top rankers are so dangerous that they are either rightfully arrogant or clinically insane. These vampires though are all talk and I can easily dispatch them only by throwing some Keys. Thankfully my custom Keys are a hybrid that was based on one used by a Servant and infused with holy element from this world based on my mother's research on sacred gears. The poor guy. Despite my mother's kindness (according to nee-san) she is still a magus and can get carried away when doing research.

I throw my black keys with trained precision and it all struck true. Good. Thanks to my training with Kaleidoscope I have clairvoyance ability, an ability necessary to learn Kaleidoscope from a certain angle. Now that I'm done with them, I turn to the exorcist girl.

"Are you okay?"

I ask her. I hold out my hand and she took it as I help her up.

"Thank you for helping me but I had the situation under control."

"I don't doubt it but can't I help a girl when I have the chance?"

"…I do appreciate the help."

"Good. So why is an exorcist here so deep in vampire territory?"

"…I got lost."

"You got lost?"

The girl nodded.

"What about you?"

She asked me. Alright, should I tell her the truth or lie?

"Well, it's complicated."

"…Why are you using crosses as weapon? Are you an exorcist?"

Okay, I should've expected that. From one glance, Black Keys are like crosses so I can't fault her from mistaking if she doesn't recognize the weapon since it doesn't exist.

"Uhh, well, something like that."

I didn't exactly lie. I was recommended by Ciel-senpai to join the Burial Agency after all and they are part of the church and I am technically like an executor even if I'm not formally one. Exorcists here are similar to Executors though not as rough in training or as crazy.

"But I've never seen your kind of weapons."

"These are prototypes based on Blade Blacksmith to make more effective weapons. Light swords are not very good against high-class devils after all. I'm one of the first to receive these since it fits my style."

Again, this is technically not a lie since I know my Black Keys are modified based on a sacred gear that could create holy weapons and I assume it is Blade Blacksmith since I don't really know the specific sacred gear. Again since these are experimental weapons created by my mother, these are technically prototypes.

"Ohh… So it is some kind of secret experimental weapon."

"Yes, let's go with that."

God, I feel like I'm fooling this girl (which I actually am). She's still naïve and somewhat innocent from my short interaction with her. Then again, this world's Church is softer than the other world's. I know the Church must have something like the Assembly of Eight Sacrament or the Agency but I doubt it's as extreme as the other world. They do have a reputation to uphold.

"Kotomine, more are coming!"

The dhampir girl whose name I forgot to ask warned me. Ohh bugger. I really hate you Zelretch. I began to look around and I finally realize that we're inside a building. It must be a high-rise since I can see multiple stairs leading downward on the building next to this one through the window.

"Anyway, what's your name?"

I ask the exorcist girl as I began to think of ways to get out of this situation. I decided that to use the same method which is Kaleidoscope. I took out the jewel dagger and was about to activate Kaleidoscope when I felt an unusual resonance.

"Xenovia Quarta, and what is that?"

She asked as she eyed the dagger in my hand. I ignore her though and turn my attention towards the dhampir I'm in charge of. She look at me shocked as her eyes went from my dagger to the glowing chalice on her hand… wait, chalice? I got a bad feeling about this.

As if answering my bad feeling, the chalice glows brighter along with my jewel dagger.

The last thing I remember is cursing Zelretch before I felt the familiar pull of the Kaleidoscope, this time much stronger and forceful. I just knew that this is his idea.

Damn you Zelretch!

It sucks, I know. I'm totally not satisfied with this chapter and I feel like I just wrote that ending for plot convenience (which is true). Now, this chapter is the turning point. I'm still considering but next chapter I will most likely dump the trio in Nasuverse a year and a half before the 5th Grail War which I will make into a Great Grail War. So I will go Apocrypha with the Grail War arc. I was thinking about saving that for later but I'm so tempted to do it that I can't help it. The servants will be a little different too. I will most likely go through with the Grail War idea but well, I'll cover some things like the time between their arrival and Grail War a little. I rarely see a DxD chara got thrown into Nasuverse anyway. Anyway, time to answer a few things like what I can reveal about Noire's Harem. Issei's harem is his usual ones minus some which is obviously Xenovia. I will give and take some from him but the core member should remain the same apart from me reasigning Gremory into a more minor role and the lead being taken by Ophis as I tend to do with Issei.

Issei's confirmed harem: Ophis, Akeno, Ravel, Koneko, Asia, Rias, Tiamat.

These are the confirmed members and I might add a few more as far as I am capable. Now about Noire's harem. Xenovia is obvious since it is me and then Valerie. I plan to add Fiore Forvedge Yggdmillennia and maybe his Servant but so far I have confirmed Xenovia, Valerie, and Fiore. Now to answer a few reviews.

dragonrider66: I always feel the Devil side actually got the best part of the deal. And you're right about Issei's Origin. This time I won't focus much on his development with Boosted Gear though. I'm still trying to play with his Origin more.

Drow79: Well I agree. 1st would suit Issei though I believe it would suit Emiya Shirou more but I can try to work with that.

Guest: Add Grayfia? To who? And what should I do with Zechsy if I were to add Grayfia to someone's harem? The only way I could make the idea fun (if I were to fit it into my story) is with Momoka dueling Zechsy since she's the only one in Issei and Noire's side powerful enough to defeat him (her and Zelretch but he is insane).

Anyway, follow and review. The more you do, the stronger I become... Mwahahahahahahaha!
