"So you're the girl, that Nicolas has been hiding behind my back?" Sasha asked.

"Hiding is a strong term to use when the bastard, abandoned me and Irina, after the Kokabiel Incident," Xenovia said.

"Well, maybe he is sad and disappointed, that his once faithful childhood friend, ended up turning into a devil behind his watch," Sasha said.

"That's!" Xenovia clenched her fist tightly in anger. "Maybe be right,"

"Either way, if you want to meet with him, it would be much harder than you think it would," Sasha said.

"Then you better help us to get to him! You still need to remember, that you need to make a good impression to yer bloody! Sister-in-law," Rei said.

"If that it takes, then so be it," Sasha without any form of hesitation agreed with Rei's plan. "But you need to book us a flight to Moscow, in under a week,"

"That can be done, I have all sorts of connections," Rei then took out her phone, and began to dill certain numbers that owed her.

"Nicolas..." Xenovia uttered with a sad tone.

"So... Wanna explain to us, how both of you meet and depart?" Sasha asked.

"It's a long story," Xenovia sighed.

"We got the time and place. Now tell me!" Sasha smiled with excitement, even though she worked as an assassin, she tended to like drama in her free time.

"Fine, we were in the same orphanage back when we were just a child, mother Griselda took care of us until we got old enough, to part take in the Holy Sword Selection," Xenovia explained, as she reminisced about the memories of their past. "He was the one who watched over me since I was a child, like an older brother figure, he is cold and selfish sometimes... And there is his greed for money habit, which tends to be a hassle for him and the rest. But he was kind nonetheless,"

"What a sweet drama," Sasha said.

"Money problem? Yeah, sounds like Caren alright," Leon said with a grimed tone, as he was tricked in the oast into giving up a lot of his savings, to the fake money-grubbing nun.

"When we were 12 years old, his abilities started to manifest which took the notice of mother Griselda, his powerful ability to create many types of weapons out of his own body. Kinda similar to Rei and Kiba's, but his is far different from Rei's, that ability of his was his Sacred Gear; Weapons Creation. A simple yet effective name, since Nicolas dislikes the complicated name or any sort of weird name,"

"What types of weapons can he create? To be exact, demonic or holy?" Leon asked.

"Not much is known about his ability, since he rarely uses his Sacred Gear, mostly because his types of weapons are far more simple. Which was a sword and gun, there was also his ability to coat his body part with a thick layer of holy aura. That ended up, making him use his Sacred Gear even less than he usually does since he prefers hand-to-hand combat rather than using weapons. For that, Mother Griselda scolded him a lot, since it was a waste of a powerful Sacred Gear,"

"That is also proven to be true, back when I first met him, the only weapon he ever used was a gun and sword, along with his fist," Sasha confirmed the story of Xenovia. "He is a far more skilled close-combat specialist, than both of you and Rei combine,"

"After we grew old enough, we part take in the Holy Sword Selection, it was a traitorous journey, but we succeeded in the end. That single day alone managed to force me to form a feeling of attachment toward him, not as a family, but rather as a lover. So for the next years, I kept on asking him, to let me bear his child since with his powerful Sacred Gear, I had a genuine feeling for him. But he keeps rejecting me! Saying, that I was too bold with my confession, and he wasn't interested in making a child cause it was a hassle,"

"I gotta agree with him," Leon thought.

"Year after the Holy Sword Selection, we were sent here in Kuoh, to retrieve the stolen Excalibur pieces," Xenovia said.

"Wait! What pieces!?" Leon said in shock.

"Excalibur, my dear, don't worry I will explain it to you later," Sasha hushed Leon by stuffing his mouth with her hand. "Continue,"

"We soon made contact with the Gremory and Sitri heiress, since they were the ones who held the authority over this city. Unlike me, Nicolas never dislikes the devil nor does he bear any sort of resentment toward them. Even though his real parent was killed by the devils, his mother Griselda told me that. So we proceed with our task, and then we meet with the fallen angels Kokabiel and Valper Galilei, who were trying to fuse back the broken pieces of Excalibur and wage another war, in the Biblical factions,"

"How the hell! Did Excalibur get broken?" Leon said with an unpleasant tone.

"Not now!" Sasha stuffed her hand again in his mouth.

"We manage to beat him, thanks to Issei and Nicolas, who figure out a plan to kill him from behind. It takes up, every single trump card that he had kept hidden throughout the years to finally kill Kokabiel, and stop the war. But after he kills Kokabiel, he decides to disappear, leaving without any sort of trace or even leaving any goodbye... Nor! Did he even let me bear his child before he disappeared"

"No wonder he left," Leon thought.

"Just like any other romance drama... Childhood friend never wins," Sasha said with a sad tone.

"It was a couple of months ago, after his disappearance, I was desperate to search for him, even Mother Griselda found the news of his disappearance. She along with the higher, was displeased with his sudden disappearance, so even till now... I keep on, trying to search for him, and now! The day had come, as my prayer had been answer,"

"That's sweet to hear," Sasha said.

"Still sour about the whole Excalibur thing," Leon said.

"Oh shush! My dear," Sasha said.

"Alright, I managed to book us a flight to Moscoe tomorrow, so get your bags ready, and meet me here at 9.00 p.m. sharp," Rei said.

"Thank you," Xenovia bowed in gratitude for Rei.

"And here, I came from Moscow to meet with my dear again, to just ended up getting back to the motherland again," Sasha sighed.

"Though, that still answers my question," Rei said. "On how, in the name of Gaia! Did you are in the possession of Durandal!?"

"Wasn't she the one that held, the Peerless sword?" Leon asked.

"Not their sword! Ours!" Rei retracted the words of her twin, who fell into shock, after the realization.

"He gave me, his version of Durandal as a celebration gift after we passed the Holy Sword Selection, he said. That he doesn't need it anymore since he had to decide to change his way of battle," Xenovia explained.

"No wonder. Why do you want to meet him, so bad," Leon said.

"Of course, you, yourself already know why? Don't you? With the whole Sasha being alive thing, and she has the Grail pieces, what sort of idiot. Would I be, to pass out the chance to meet someone, that probably know the detail of why we are even here in the first place,"

"That's a resonable answer, but getting to Nicolas is much harder than you think," Sasha said with a sigh.

"Why?" Xenovia asked.

"Because he already known, that we all are heading to him, look," Sasha pointed her finger through the window.

A black feather fall from the tree, no one know what the feather was, but Xenovia and Rei already identify, that the black feather belong to a Fallen Angel.

"He already sent one of his spy, to track me from behind," Sasha said.

"Did he ally himself, with the Fallen Angel?" Xenovia asked with a serious tone.

"Ally? That is a strong word to use, I would rather use the term partner," Sasha said.

"Dammit!" Rei smashed her fist to the wall in rage. "We had been had!"

"Not entirely," Sasha gained the attention of everyone in the room. "We still haven't truly know, what Nicolas is planning yet. Either he decide to escape, which is a higher chance to happened, or just meet with you, which will be a lower chance to happened,"

"Screw it! We're taking that damn gamble! We're going to Russia tomorrow, so Leon you stay here with Saber and guard this place!" Rei commanded her other twin.

"Why us?" Leon asked.

"Because, you have nothing to do with this mess, and I am really sure, that you won't even join my search. Because you want, a normal life before we meet with Chaldea," Rei said.

"That... Is true, fine, me and Saber will guard the place until all of you arrived back safely," Leon said.

"And inform me, if anything bad or stupid had happened, while I was gone," Rei said.

"That can be done," Leon said.

"Alright, Xenovia, had you tokd your peerage and boss, that were going out of the country yet?" Rei asked.

"I have, and she does not like it, one bit," Xenovia said.

"We will return back to Japan, under this week, since the boss need you to win the Rating Game with her," Rei said.

"Then I shall pack my bags, before we go," Sasha then sink into her shadow yet again, leaving the house.

"I still... Haven't got used, to that," Leon shruged.

"Whatever, just keep this house tidy and safe, once we return," Rei said.

"On it," Leon reply.

"Then let us go! And meet this, Nicolas person!" Rei said.

(Change POV)

"Boss! We have trail back the remaining trace of Beast VI! We finally, found a clue on where she went!"

A guy suddenly burst out of the wooden door, as that guy was about 180 cm tall with a bulky build of a body, wearing a dark green jacket with the symbol of a white flower on his back. His face looks laid back, with a single piercing on his left ear, even though he might look like a laid back guy. He was on alert this time, with a tablet he hold in his hand, and the way he spoke out was in panic.

Currently, he break through the wooden door of a bar located in Moscow, as he can see, the rest of his fellow crew are sitting in peace. Drinking, and eating whatever food or beer they had, but once they heard his declaration. They stopped what they were doing, and turn all their gaze directly toward him, the informant didn't care about the stare. Rather he move on, trying to find his boss, who was sitting on the seat of the bar they are in.

"Boss! Did you hear me? We found, Beast VI trail!"

"Really? Then do inform me,"

The one the informant was searching for, turn his head back, with his tan and tone down or relax facial expresion, he wasn't that alert on the sudden finding. Since, this wasn't the first time it ever happened, he was a tall and slightly bulky, as he stand in the same height as the informant. With his sharp slick back violet hair, and ember eyes, he wore a red scarf around his neck, and the same exact jacket the informant wore.

"Paimon, manage to caught up the sense of Beast VI, back when we meet her in Sweden. After months! Of endless detective work! We finally know, where she went, and you wouldn't like this at all... Boss,"

"Now you got my interest! Tell me, where did she went?"

"It's... The Bibical Underworld,"

There was a silent moment of pause in the bar, once they heard the words that left the informant mouth, but the tan man quickly accept the fact.

"Ah shit... Here we go again,"

"I know right? I mean, we might spend only a few months in their underworld as a lab rats... But once we escape, we were branded as a top criminals for crying out loud!"

"What happened with Kuroka back then, to think, were going back in there yet again... After the destruction those four extra classes servants had cause, we are in quite the deep shit!"

"Yeah, their defense have been upgraded when the extra classes attack them, so sneaking back in there. With our affinity! For being the vessel of their true ancestor! Will be a pain in the ass,"

"So what do you think, Bael?"

[Do what you must, if it mean, Beast VI will be out of the picture. It is a risk, worth taking,]

A cold and menevolent voice, calls out from the tan man mind.

"What did the king, told you?"

"He said, if it mean Beast VI will be gone, then it is a risk worth taking,"

"So... Do I informed, the rest about this information, so we can get ready?"

"Be quick! And get our Assassins class in their top peformance! We will need them, the most!"

"On it!"

With that, the informant left the bar in a hurry, as they need to quickly prepared their necessary tools if they want to venture out, to the Bibical Underworld yet again. It's bad enough, that they had become the most wanted criminal in the Underworld, but now, they need to deal with Beast VI renmant and the entire Underworld on their back.

Fate truly is a bitch!

"Bael, how much of a problem would it be for us, to rampage through the entire Underworld, along with revealing our true existence?"

[Do you even need to ask?]

"Yes, because most of your decesendant, are the one in charge with the Underworld. If maybe, we can made contact with them, by using your conection with them... Then maybe, we can form a patch with them, which will make hunting Beast VI, far easier,"

[That is a reasonable option, but I strongly disagree, with the current state of the Underworld. Their situation is very delicate, with the death of their God, and lossing most of their power to the extra classes. They will try and force us, to be a hope for them, to reach up into a far higher rank,]

"Aren't you quite sad? Seeing your decensendant in a bad state? Won't giving them hope, and eleminate Beast VI with less causalty, the best option?"

[It does, but I am not a demon that give false hope, unlike Goetia... The version of the 72 pillars are vastly different from us. Our goals are widely different, as if I give them a false hope, our ideology will clash and cause another civil war. Which is something I dislike, even though they are my decensendant, I must be the one who watch not help. You already see, what happened to thr 72 pillars of the Grand Order timeline, don't you? Then don't interfee much with them, as we are here to only eleminate the remnant of Beats VI,]

"Well, you're the boss, then let's do it your way... Just pray, that we won't cause another set of problems in the Underworld,"

[That is something, that only you can do, not us,]

"Let just hope, the worse won't happened,"

Suddenly, his phone rang, as he saw the caller, it was his right hand man calling him, which must be for the trip to the Underworld again.

"Boss! The car and units are ready! Were awaiting for your arrival!"

"Alright, wait there! I'm coming with the rest, oy! Kruger, Xin, Claude, Yeager, Herry, and Jacob! Get all your asses ready, were going to finsihed, what we left years ago,"

Hearing their boss command, the one who sat on the bar, takes out their weapons and tools that will be essental for the trip. Guns, bomb, armor, close combat weapons, and ammunition. Currently, he only calls out the captain of his command squad, as this respective name, are the vessels of the 72 pillars. The rest of their mens, soon follow their command, and takes out all the hidden weapons in the bar.

"Rider of Iron Flower... In the name of the boss lady; Alaya! We're heading out!"

Disclaimer: I don't own Fate and DxD

Note: the next chapter will focus more on Xenovia relationship and past, since I think, that using her character as the good way. So that the Rating Game will held Riser as the winner, since he is in possession of an anti-dragon Mystic Code. For Rider of Alaya, they will also partake in a mess that will soon ignite in the story, their identity will be revealed soon. As they are a fan servant, but I used character from other anime that had some sort of relationship with the 72 pillars even thought, it was through their name only.

I think, the idea of another timeline from the future, the 72 pillars did not become Beast I rather they decide to just watch and see how humanity progress. Until they finally decide to interfee, and help them to solve their mess, is quite the solid backstory. Then again, the anime character I used already had the same thing, except their 72 pillars aren't alive nor from Fate.

So in this story, taking how their 72 pillars work on their world, I will give them a powerful advantege when they face agaisnt an angels and fallen angels. Since I also want, a demon vs angels in this story, a demon and angels from Nasuverse, duking it out, like there is no tomorrow. So in the future chapters, a batch of fan made angels from Nasuverse will also join into the chaos.

For the character I used for Rider, you can guess it, and maybe your comment is right on the money.

So stay toon, and bye 👋
