When Xion woke up she was...pretty confused. She was lying in a Bedroom she never saw before.
"where...am i?...Huh?" She wanted to stand up but realized there was something warm behind her. She turned around...and ehr Face became scarlet red. Right next to her was a beautiful, red haired girl...and she was naked...and than Xion released to her horror...she was naked too.
"AAAAAAAAAAAAAAAAAAAAAAAAAAAAAA" Rias was woken up from her sleep when she heard a loud scream. She immediately stood up and looked at her new Pawn. Xion had jumped out of the Bed, raped the blanket around herself and was pointing her Keyblade at Rias.
"WHO ARE YOU? WHY ARE YOU NAKED? NO MORE IMPORTANT WHY AM I NAKED? WHAT DID YOU DO WITH ME?" Rias couldn't help but chuckle. Xion probably TRIED to be intimidating but her naked body, the pink blanket and her scarlet red face made it rather difficult.
"My my quote energetic in the Morning are you know my cute little Servant" Somehow Xion's face became even more red.
"S-S-S-SERVENT? I-I AM NOT INTO THAT KIND OF STUFF" Rias just smiled at her and began to get dressed.
"Tell me...what do you remember of last night?" First Xion was confused.
"(Last night? What ha...)" Xion froze. Instead of Scarlet red her face was now white as a ghost. Her Hand went to her Chest where the spear pierced through her.
"So you seem to remember. I be blank with you...you died. And you still would be dead if i had not Saved you" Xion looked confused at the now in her Black Underwear dressed Girl.
"Saved me?...How?" Rias took a deep breath.
"I ask you to listen me out and don't judge me until you heard the hole Story understand?" Xion gave a nod.
"Weary well...firstly the beeing you encountered last night was known as a Fallen Angel. They ounces served God but fall out of his grace because they committed a Sin. She killed you probably you got in the Way of her original target, a Boy named Issei Hyoudou. Who i hope is still alive. Now how i saved you...i am not a Human." Too Xion's surprise 2 Leathery Bat Wings grow out of Rias back and to her even bigger shock the same happened with her.
"I am Rias Gremory. Heiress of the Devil Clan of Gremorey. And i reincarnated you as my new Devil Servant." Xion blinked not really sure what to think. But then she narrowed her Eyes and grabbed her Keyblade with both Hands ignoring her nakedness. Rias noted that the tip of the Key like blade startet to shimmer.
"You are a Devil?" Rias nodded.
"Yes and i know what you're thinking but i can assure you i do not men you harm...listen i know this is much for you. But i swear on the House of Gremory that i am here to help you. Let me explain a bit more. Over a Thousand years ago we Devil's waged a war with the Forces of Haven and the Power of the Grigori. The Angels fought for God, trying to wipe out both there Former Fallen Comrades and us Devils. We Devil's tried to wipe out all Angels because there Light was such a strong Weapon against us and the Fallen wanted to wipe out us Devils either to claim Hell as their own Territory ore to get back into God's grace. The War raged for centuries and in the End no one came out victorious. The War ended with a installment but all in all we Devil's probably where the ones who lost. The original 4 Satan's where killed in the last battle...and shortly after that we Devils had a Civil War between those who followed the Ways of the Original Satans, hellbend on returning to the War and those who wished for Change. That was the side that ultimately won but at a huge cost. Our Race was reduced immensely and sadly we Devil's have extremely low Birth Rates. To put it into perspective for you my Brother and his Wife married ruffley at the end of the Civil War which was Centuries ago. Since then they wanted a Child and only 13 years ago was my Nephew Born. Same with me my Brother was already an Adult when the Civil War broke out and i was born 17 years ago. As you can sea it would be near impossible to bolster our Numbers this way and the Fallen and Haven at any point could wipe us out. So one of the 4 new Satans developed the Evil Piece System...and yes i know it sounds evil but at that point we gave up to try and change the People's view that we were not evil so we decided to just roll with it. Do you know Chess?" Xion just gave a nod.
"Good. The Evil Piece System is based on Chess. A High Class Devil is given the King Piece with 15 additional Chess pieces. Those Chess Pieces allow us to reincarnate other beings as Devils. We call such groups a Peerage. I explain the details on a later date but basically that is what i did to you. I youse my 8 Pawns to bring you back to life...it was the only way of saving you and." Xion calmed down a little and lowered her Sword...and then also remembered that she was standing completely naked in front of Rias. Once again red faced did she start to cover up.
"A-And why am i naked? Where are my Clothes?" Now Rias looked a little sheepish.
"Weeeell...your Clothes are probably beyond Salvation. After all they had a Giant Hole in them and where soaked in your Blood. So sorry on that part. And why we were naked well...a King can heal his Peerage Members but it requires Skin to Skin contact. The more Skin the better. Normaley the reincarnation would subdue but you lost luch blood so i wanted to be sure. Now than i guess you want to get dressed. I have not much in your size so i am afraid this will do until we can go Shopping" Rias gave Xion a simple pair of Underwear and a Black Dress.
"Considering you only where wearing Black yesterday i assumed it was your favorite Colour. OF your Boots are by the way down Stairs. I will wait for you." Rias left the room to give Xion some privacy. While alone Xion hat time to think.
"(So...i am now a Devil? But aren't Devils creature of the Darkness?...but...i guess she seemed alright...)" she looked at her new Wings.
"...i just hope this all goes well."
A few Minutes later Xion came down the Stairs of the...quit luxurious House they where in.
"A wonderful there you are...i...i completely forgot to ask you you're nama hehe" Embarrassed Rias rubbed the back of her head.
"My name is Xion i...guess it's nice to meet you" Rias gave a nod.
"Ah warey well Xion. Follow me it is time you meet you other Peerage Members" To Xion's surprise a glowing Circle appeared Under Rias Feet.
"Jut step in don't worry we will simply appear in our Clubroom." A little hesitant Xion stepped into the Circle and a bright light indulged her. Slowly they sank into the Circle and re emerged in a completely different room. They now wheare in a quite old looking Place. Two Couches where sitting there facing each other with a Table between them. There also was a Desk in front of them. 3 People were currently here. One was a small Girl with white Hair and yellow Eyes. She was eating some sweets, not paying attention to anyone. Right in front of her was a rather handsome Boy with blonde Hair. He smile when he noticed the two. The last Person was a Girl in Rias Age. She had long black Hair, tied into a Ponytail and purple Eyes. She was just as well developed as Rias.
"Welcome back President. Ah i guess that is our newest Family Member" Said the Black Haired Girl.
"You are correct Akeno. So it's time for introduction. My Peerage this is Xion my new Pawn. Xion this is Akeno Himejima mu Queen, Koneko Toujou my Rook and Kiba Yuuto my Knight."
"Ahm...glad to meet you? I am Xion"
"Ara Ara quite a cute one are you know? But President i am confused. Wasn't Issey-Kun suppose to join us?"
"Yeah about that...it seems Issey has vanished since last night. My familiar was not able to find him anywhere in town" Said Rias. Kiba looked worried.
"Could he have been taken by the Fallen?" Rias wanted to say something but Xion was faster.
"Is...Issey a quite average looking boy with Brown Spikey Hair? Because if he is i helped him escape last night." Rias turned to her.
"You did? Do you know where he is now?" She was hopeful that maybe she could regain this Powerful Sacred gear but her hopes were crushed when Xion shook her head.
"No. I...just opened a Corridor. I did not think of a Destination. He could be anywhere"
"...Corridor?" Was all that Koneko asked.
"Well...it is something i can doo...(Should i show them?...can i even do it without my Cloak? Than again if i only do a short distance...)" The Devils all kinda got scared when suddenly Xion gets indulged in Black Smoke and just disappears, only to reappear a Second later on the other side of the Room.
"This is a Corridor of Darkness. They are youse as a fast mean of Travel...the problem is...without my Cloak i can not safely use it often or for too long distances. I did cast a Protection Spell on Issey but...for all i know he could...oh god...what have i done?" Only now realized Xion what exactly she did. Issey...was most likely not alive anymore. Either completely consumed by the Darkness ore turned into a Heartless. The best Scenario was that he is stranded on some random World without a way to return home.
"X-Xion? What do you mean? Is issey in danger?" Rias got really worried when Xion started to panic then...then she started to cry and slowly slid down the wall.
"..;he...he is most likely dead...consumed by the darkness...lost forever...i-i killed him...i killed him" Rias Heart fall down. Not only because Issey was apparently dead beyond safing...but because it was her fault...and her new Pawn blamed herself for it.
"...It's not your fault. Listen calm down. You said you cast a protection around him? So he could still be alive." Xion wiped away her tears and looked up.
"But i am not good at the spell. I-I couldn't even use it on myself to search for him i-i acted without thinking..." She cried even more.
"...Sacred Gear" Everyone looked at Koneko who looked slightly worried for her new Peerage Comrade.
"OH right. Issey-Kun probably had additional protection from his Sacred Gear" Exclaimed Akeno.
"Sacred...Gear?" Asked Xion confused.
"Sacred Gears are special artifacts granted by the god of the Bible. If it is Indeed as powerful as i assume than it would be a Longinus Sacred Gear. Considering the Draconic Aura surrounding him it is most likely one of the Two Heavenly Dragons. Booster Gear ore Divine Dividing. But i am surprised that you don't know about Sacred Gears considering you have one. That Giant Key of yours."
"...ahm...the Key Blade is not one of those...sacred gears." She started to calm down, hoping that what they were saying is true. She stood up and summoning the Kingdom Key...only now realizing that it looked different. The Arm guard was now made out of the same Bet Wings she now has hidden on her Back. The Blade was now a mix of Black and Red and the teeth also resembled Bat Wings. The Chain was a Scarlet Pawn piece.
"That's...not how it looked like before..." She looked at the Blade and new its name. No longer the Kingdom Key. This...was the Devil Key.
Kiba stood up and came closer to look at the blade"I must admit a fascinating blade. I would love to have a small sparring Mage later if you don't mind. But are you sure it is no Sacred gear?"
"Yes posi tive. The Key Blade chooses its wielder and there are multiple wielders at once all having their own Blade...more or less. Sora, Roxas and i kinda had the same. We all 3 used the Kingdom Key. But Roxas switched to dual Wielding two different Keyblades and even Sora relied on a multitudes of Blades" Kiba nodded in understanding.
"Is it safe to try it?" Xion nodded and handed her Blade over. Kiba inspected it when suddenly it disappeared. He was scared for a short moment. The Blade disappeared in Red and Black Energie, similar to his Kings Power of Destruction. But it immediately reappears in Xion's hand.
"Puh...was kinda scared there. But truly a magnificent Blade." Rias sightet. She really hoped Issey was ok. She didn't even care anymore to take him into her Peers just hoping he was ok.
"Okay Guys how we eat Breakfast and than explain more of devil life to Xion?" Everyone agreed and they sat down to eat some Pancakes and Tea.
