A/n: Yea, so Xenovia and Irina are in the story now. Probably part of the Harem as well in regards to Irina. Thinking it through now. Anyway let's get this started.
(Start)(Y/n P.O.V)
I was sitting on the couch within the ORC club room. On my sides were Irina and Xenovia who were both holding onto my arms. They were smiling at me. I noticed how the others seemed slightly jealous. Turning to Irina I talked with her a bit.
Y/n: So Irina you and Xenovia are here to find out what happened to the excalibur fragments.
Irina: Correct. Though we also came to see an old friend.
Y/n: An old friend? Do I know them?
Xenovia: Silly Y/n. The old friend is you.
She said as I turned to her. I noticed her face was close to mine before a smile appeared on her face.
Y/n: Don't you-
I went to say only for her to push our lips together again. I heard the door open as I pulled away and saw Raynare standing there.
Raynare: What were you doing?
Y/n: I didn't have a choice.
Xenovia: Who ever you are, I hope you don't plan to get in my way for Y/n.
Y/n: *whispers to Irina* Help me.
Irina: Don't worry, she won't try anything extreme...I think.
Rias: Xenovia. Can we please get back on topic,
Xenovia: Fine. I want all of you to stay out of this. This is the churchs mission. Our mission.
Rias: Your starting to give me the idea that you don't trust us.
Xenovia: And should I have a reason to trust a devil?
Rias: That is a fair point, but we do want to try and build trust between our factions.
Xenovia seemed to pause before a smile appeared on her face as Raynare stood next to Rias.
Xenovia: Alright. I have a proposition for all of you.
Rias: Oh and what is that proposition.
Xenovia: Simply. Irina and I will face two of you in a fight. If you win. We follow your rules. If you lose. You have to stay out of our way and Y/n must come with us.
Y/n: There's no way that she will-
Rias: Deal.
I looked at her with a slight glare of annoyance as she shrugged with a cocky smirk.
Rias: It's simple. They can fight the Isami and Kikiyo. I have faith in my knight and pawn.
I could only sigh as we all walked outside.
(Fight is the same as it was in cannon. Just Issei and Kiba are woman)
I was shaking my head in annoyance as I looked at Rias who could only give me a sheepish smile. Walking over to her, I chopped her softly on the head. She held where I hit her as I felt something hold me from behind.
Making the arms let me go, I turned and saw Isami looking at me with tears in her eyes. Wrapping my arms around her. I smile lightly.
Y/n: Don't worry Isami. I'll be back once this is all over.
Kissing her forehead, I walked over and did the same to Kikiyo before I stood by Irina as Xenovia had a gleam in her eye.
Y/n: I'll be back everyone.
With that said, the church members and I all walked out.
During the walk, Xenovia hadn't let go of my arm while Irina brought us to the abandoned church. Dragging me inside, I was placed on a chair as they both used me as a pillow. Xenovia placed her head on my lap while Irina laid her head on my shoulder. I placed my hand on Xenovia's head while I placed my other arm around Irina's waist. We fell asleep like that.
(Early in the morning the next day)
I was awoken when I heard Xenovia and Irina's voices. Opening my eyes, I wasn't able to see them. Standing to my feet and walking around, I followed their voices till I found them sitting around the edge of a small pool. I blushed heavily as they were both naked. Turning around and walking into the main hall, I was distracted and didn't notice as a foot came in contact with my face.
The girls looked as I crashed into the room. Moving quickly, they got dressed as someone walked into the room. That someone was Freed.
Xenovia; What are you doing here?
Freed: I came to check on some things and I find the Abyss Walker and two members of the church.
I saw as Irina looked at me. Standing to my feet, a drew my Abyss Greatsword out of the ground as my right arm was covered in my armour.
Charging Freed, I was forced to block an attack as he swung a strange looking sword at me. Jumping back, I stopped as Xenovia and Irina drew their own weapons. Looking at them, I felt the holy energy flowing the blades.
Y/n: Let's do this. Follow my lead.
I charged Freed as Xenovia followed. We clashed Blades with Freed as Irina attacked him from behind. He tried to dodge only for me to partially activate my balance breaker. Grabbing Freed with my left arm, I slammed him into a wall and dragged him across the wall before slamming him into the ground. Letting him go. I looked over to his sword that was embedded in the ground. Moving to grab it, the sword disappeared in a bright light. Turning to Freed, I watched as he disappeared the same way. Focusing on the energy signature, I found it to be similar to the one of Raynare's.
Y/n: I think I know who's got that Excalibur sword.
Irina: Who?
Y/n: From the energy I can tell that they were a fallen. And I think it would be the one Fallen who is a warmonger.
Xenovia: Kokabiel?
Y/n: Yea. We need to inform Rias.
I turned around only to feel a burning sensation in my left hand. Ignoring it I walked off to my home knowing that Rias would be there.
(End)
Alright. So the fight with Kokabiel will be soon and who knows what Xenovia has planned in her head. With how she's acting, how will the girls of Rias's peerage react when she eventually tries to keep your to herself and have your children. Only time will tell.
