AN: My muses compel me again to write this snippet. One that binds together the most unexpected of two Nasuverse and DxD characters together. My attempt at writing something a bit more emotional. Don't expect updates much. I write whenever I'm in the mood to. Best to play the OSTs that appear in the story for better immersion into the story. I write this with what little I know of Fate and DxD lore. I'm not a full-fledged expert with either works - though I'm more aware of the Nasuverse stuff most of the time - so dont bash me for my lack of knowledge or grasping at straws.

[FGO OST - The Corridor of Memories]

3rd POV

Yasaka couldn't stop dreaming about her.

She didn't know when it all began, but one day she suddenly dreamed of a girl.

A girl with long wavy brown hair and brown eyes. She wore a plain brown school uniform with black leggings.

At first glance, she looked so plain that one would imagine her an NPC from a game. A girl whose face was cute and yet at the same time very plain and monotone looking.

She was a soul that looked human and yet was not. She was one born not of the Earth, but the Moon.

Her origins was nothing, a soul that was materialized on the world of the Moon.

Fitting her plain appearance, she didn't have any motivation nor did she have any dreams or wishes to call her own.

She lacked the instinctive drive and will that fueled other human beings.

Thrown into a war that she had no knowledge of and unprepared for, she would struggle in the beginning.

For while the hundred others all fight for the sake of their own wishes, goals, and dreams, she had none to fight for.

At first Yasaka found herself uninterested in the girl. But overtime, her perceptions and opinions of the girl would slowly change.

Although granted many different companions called Servants, the girl would die again and again.

Each time she died, she would revive and her war would reset to zero.

At first, her newly found motivation was to live. To survive in this digital war taking place on a different world on the Moon.

But over time, as she was struck down and killed, she would renew her determination and effort. Yasaka's feelings for the girl would start to warm up to the girl.

Each time the girl revived to fight once more, she expressed more emotions even though it was subtle and one needed to pay close attention to the monotone girl to notice. Feelings for her Servants, feelings for her enemies, feelings of happiness, joy, sadness, love, despair, anger, sympathy, compassion, selfishness, kindness, pride and so much more. The girl's charming points were beginning to come out for Yasaka. She was like a cute adorable little squirrel. Her classic signature move being the SHAFT tilting of her neck as she looks at a person. For Yasaka, it was becoming less of a randomly coincidental dream and the events becoming more real with each dream sequence.

Throughout her journey to survive the neverending war, the girl had many Servants who call the monotone girl their "Master", although rarely would all the Servants be together in one moment or scene. There was the energetic majestic swordswoman in crimson red dress who was always cheerful and smiling, an empress with a passionate heart of an artist. An Archer in red and black, wielding yin and yang colored twin dao swords, who dots on her like a mother hen. A golden king whose sword had immeasurable power, declared her his dear friend and worthy queen. The white titan who is the avatar of destruction, the harbinger of the end of civilization itself. A holy knight king of fantasy whose legends and chivalrous order is comparable to that of Arthurian legend.

But out of all the girl's companions who fought on her behalf, none had grabbed Yasaka's attention more than the kitsune dressed in blue shrine maiden clothes who only wants to "become a good wife". The comic relief among all of the girl's Servants, being a goofy, silly, and cheerful young fox girl who easily fell in love with her Master and has devoted herself to becoming her Master's wife. For some unknown reason, Yasaka felt some sort of familiarity with this wifey kitsune. It was something was resonated deep inside of her when she looked at this particular Servant. As powerful as she is, it felt as though it was only one part of a greater whole. Furthermore, Yasaka felt some sort of primorial connection to this Caster Servant despite having never seen this particular kitsune in her entire life. Yasaka could feel the warm flames of Amaterasu stirring inside her whenever she saw this Servant she nicknamed "Mikon". Just who is she? Who is this mysterious kitsune Servant of the monotone Master that she always dreams of?

In her dreams, Yasaka would root for the female Master. Cheering her on at her great triumphs, screaming in pain and despair at her moments of defeat, and cry during those rare moments when the Master cried herself. Of all the things that made Yasaka cry the most for the girl was seeing her and the Red Saber in the final battle of the war against athe powerful Buddha-like figure, his golden light striking down the Master's beloved Saber as the girl slowly faded away dying from severe wounds, losing both legs and one of her arms. The girl's eyes filled with sadness and regret seeing her dear Servant fall before her. Yaska reaches her hand out to help the girl, to save her somehow. But she could not touch the girl she became attached to in her dreams, her hands phased through her. Yaska screamed for the girl to stay awake and fight to live, but the dead girl did not respond, leaving Yasaka to cry in despair as she pleaded for the girl to open her eyes. Yasaka's heart breaks as she sees the life in the girl's eyes fade away before just as the Red Saber hit the ground dead and the shadow of darkness covered the battlefield [AN: Yaska is dreaming of the opening scene to Fate/Extra: Last Encore].

That particular death of the girl shook Yaska so greatly that Kunou had to shake her awake as she was scared not knowing why her mother was crying loudly in her sleep. Yasaka would calm Kunou down, reassuring her child that she was just having a bad dream, but even she struggled not to cry. Despite her power being on par with that of an Ultimate-class Devil, Yasaka felt entirely helpless and powerless as she could only watch the heroic struggles of the girl desperately trying to survive each war, only to be killed each time. And when she has seemingly won one war and things seemingly ended on a happy note, she is thrusted into another war within the Moon with new threats, new enemies, and new twists, to repeat the cycle of fighting and dying over and over and over again. She cursed the Gods, the Angels and their Fallen brethren, the Devils, Ophis, the Great Red, and everything else in between for whoever was responsible for subjecting the poor girl to this cruel fate and suffering. Surely it was a fate worse than any Underworld and Hell there was. Although she was still uncertain of her feelings, Yasaka knows two things. First, that she cared dearly for the girl that haunts her dreams. Second, was that she wanted for her to be happy. To be free from the pain and suffering of fighting endless wars on the Moon and live her life on the Earth happy like a normal human girl. To give her the love and care that she deserved, although whether that love was romantic or motherly Yasaka was still unsure. What yasaka does know is that her love for that girl was real. To that end, Yasaka was determined to free the girl and save her somehow from the world that resides on the moon that is her hellish prison.

Yaska had not been idle when she started to take these dreams seriously. Spurn on by the way the girl had died horribly, she started looking for a way to get onto the Moon somehow so that she could somehow free the Master from her suffering. Sending inquiries to Tsukuyomi-no-Mikoto (the Japanese god of the moon) and other lunar deities to search the moon itself for where the mysterious hidden "Moon Cell" could possibly reside, she was dismayed to find that none were able to find anything that she was describing in their search of the moon, physical or magical in nature. They thought she was losing her mind and some few youkai thought so too when Yasaka became obsessed with the moon as she started to develop a habit of staring at the moon for long periods of time, thinking about that plain yet cute human girl.

Her dreams of the girl would come to an end when a new threat emerged into the world of the Moon, far different from the ones she had seen before. Calling themselves Demon God Pillars, they sought to destroy the Moon Cell and everyone and everything living in it. Yasaka's favorite heroine would rise to challenge them her defiance along with the other Masters and their Servants. But sadly it wasn't enough as the mastermind of their demise emerged himself to put an end to their futile resistance, Solomon. Even with the power of the Regalia and the hidden power that resided within the girl all this time and finally unveiled for the first time - The First Magic: Denial of Nothingness - it still wasn't enough. Solomon merely brought in more of these "Demon God Pillars" and eventually the girl and her Servants and allies would be overwhelmed and seemingly perish, their world on the Moon incinerated. Yasaka would dream of the girl no more. After that particular dream, the girl that Yaska has come to cherish as much as her daughter no longer appeared in her dreams. In her dreams, Yasaka cried for the girl to come back but the girl did not reappear in her dreams again. It was although she no longer existed. The girl's vanishment from Yaska's dreams caused her to sink into depression and for a while she would be melancholic and forlorn in her mood. Surely she was too late. She could do nothing to help the girl now. She must have surely died at the hands of the being known as Solomon. Yasaka grit her teeth in rage and anger at the name of one of the most prolific figures in the religion of the Biblical factions. She didn't know if Solomon's descendants existed and resided among the ranks of the Hero Faction, but she swore that if Solomon's descendants did in fact exist then she would kill them herself.

Ahnenerbe - Temporary Local Chaldea HQ in DxD "canon-verse" Singularity

Hakuno Kiminashi POV

Status: On-Duty Staff Manager

[FGO OST - Familiar Melody]

All Ahnenerbe restaurants are linked to one another, thus allowing "people who under normal circumstances cannot meet each other are able to meet inside. When characters from different worlds or timelines meet in this shop, any discrepancies are eliminated so that they can appear at the age that they were introduced. It is convenient as a place where parallel worlds and alternate dimensions meet. Though not all Ahnenerbe restaurants across the Kaleidoscope are fully staffed and operated. Some Ahnenerbe restaurants are left empty and dormant as they remain unused by the owner George. In the case of the Ahnenerbe restaurant that exists in this progenitor world that served as the basis for [Holy Man], in Kuoh Town, it has been commandeered by Chaldea under the advisement of Zelretch the Wizard Marshal with permission from George. It is to be used as their primary local HQ for the duration of their stay as they try to find out what was causing the Singularity that is taking place in the alleged "canon-verse". The Chaldea Masters and Servants got to work renovating the place, enlarging the restaurant from a small coffee shop to a large yet humble restaurant both on the inside and outside including the subfloors. While the first two floors were for official restaurant business, the next upper floors and subfloors were served as living quarters and other necessary utility function rooms (e.g. communications, supply storage, magus workshops for Masters, Summoning Room, Training Simulation, etc.) for Chaldea business. The restaurant business served as a front for Chaldea operations, with each Master and their Servants on rotation running the place.

Unlike before, Shirou opted to not go to Kuoh Academy like last time on strict orders from Zelretch who said that "it has been done so many damn times that it bored him to tears." Instead, Ayaka Sajyou and Sieg would attend Kuoh Academy as part of Chaldea's covert operations. Since Shirou wasn't going to Kuoh Academy, neither did Xenovia and for good reason - she might risk running into her counterpart and jeopardize Chaldea's entire operation. That was to say that Shirou wasn't happy with the arrangements as he was happy enough being stationed in the kitchen cooking up food for the Ahnenerbe's visitors. For a while, Chaldea was able to maintain cover at Ahnenerbe while investigating what was causing the SIngularity in DxD canon-verse. The restaurant proved popular with the residents of Kuoh Town both in its food and the people who staff the place. Some Chaldea members have even garnered fans among customers who came just to be served by particular Servants or Masters. This is the case of certain masochist customers who wanted to be verbally abused by SAlter and JAlter both dressed in maid uniforms and others to be dominated by Servants like Medb and Carmella. The female customers really did love handsome Servants like Arthur Pendragon in his white uniform and the Knights of the Round Table. In fact, both members of Gremory and Sitri peerages have visited Ahnenerbe for food and drink and to hang out with no one being the wiser to the true nature of the restaurant. The Perverted Trio visited once only to be traumatized for life by certain Servants like Astolfo and Chevalier de'Leon. One close call came when Kuroka stalked Sieg into the restaurant as she smelled the scent of a dragon on him and the Gremory peerage was interested in him for a brief while; obviously they mistaken Sieg's dragon scent for Issei's. Another close call came when Griselda, Irina, and canon Xenovia came into the restaurant for food, forcing Saber Xenovia to hide herself from view while the native Church Exorcists ate their meal.

However, despite Chaldea's best efforts it was only a matter of time before attention came their way. Hakuno remembered when Ayaka cursed Shirou's E-rank Luck for somehow getting himself and his Artoria Pendragon Servants involved in the Excalibur incident that was going on, though Ayaka could hardly fault him as Arthur Pendragon also got drawn into the matter. After the Excalibur incident was resolved, Saber Xenovia nearly had a murderous fit when she saw her other-self forsaking her humanity to become a Knight in Rias' peerage, showing up in front of her not as a human but as a Devil. It was scary seeing how Saber Xenovia looked at her other-self the same way Archer EMIYA once looked at Shirou during the times he tried to kill his younger self in the 5th Fuyuki HGW. It was only due to Shirou with some help from Archer EMIYA and Demiya to restrain and reason with Saber Xenovia that she did not just walk up to her Devil counterpart and kill her right on the spot inside the restaurant in front of civilians and Devils. It was a miracle that Xenovia didn't expose her true identity, passing off her name as "Elesia Bow," born a simple person from a remote village in France. Though there are already obvious cracks in her cover story as Griselda and Devil Xenovia had started suspecting Saber Xenovia although they haven't got a clue who she truly is. Saber Xenovia had not been quick to catch on when Griselda spoke a few words of French to her; though Saber Xenovia was saved by the efforts of Sieg and Jeanne who telepathically whispered French words so that Xenovia would answer back in full. Griselda already spotted some semblance between Devil and Saber Xenovias, despite Saber Xenovia now sporting a new hairstyle and wearing glasses to resemble a certain Executor from the Holy Church's Burial Agency (AN: i.e. Saber Xenovia is sporting the appearance of Ciel from Tsukihime, the redesigned art by Takeuchi Takashi). With Devil Xenovia it seemed instinctual, like there was a resonance between the two even when they both couldn't stand each other's presence; just like Shirou and Archer once in the 5th Fuyuki HGW.

A lot has happened since then, but now was not the time to think about it. Anyhow, it was time for Hakuno and her Servants to start their rotation now as staff of Ahnenerbe. The All-Liz band, Caster Nero, and Nursery Rhyme started setting up their acts to perform and entertain while Tamamo Cat and Archer EMIYA took their posts as chefs preparing meals and Hans Christian Andersen manned his post at the bartender's bar preparing alcoholic drinks. As the on-duty staff manager, Hakuno picked a table for herself and Tamamo Vitch as the two got down to calculating the budget and doing inventory for Ahnenerbe and Chaldea operations, trying their best to ignore the jealous stares from Caster and Lancer versions of Tamamo-no-Mae. As much as Hakuno tried to focus on paperwork, there are times when her head is up in the clouds as she reminisces past memories. How "Solomon'' and the Demon Gold Pillars incinerated the Moon Cell. Then her waking up at Chaldea from her dream status pad, meeting her other fellow Masters Shirou, Ritsuka, Gudako, and Ayaka, with Sieg being the last Master to join Chaldea after the Orleans Singularity. The adventures, bonds, trials, and tribulations she experienced together with her fellow Masters and the Servants she eventually reunite with. The Masters she fought alongside with becoming like her family, her siblings, with Shirou being like her big brother figure in contrast to Archer EMIYA's motherly hen figure. Her mental wondering would break when the door opened and the Gremory peerage came in this time with two other important guests and their youkai escorts. Nero greeted them and exchanged pleasantries as she got them a table close to Hakuno's. Only one person wasn't moving as she remained still at the entrance. This person originally stared at Nero with wide eyes as though in disbelief. The woman then looked around and as she spotted more of Hakuno's Heroic Spirits, her eyes became more wider as though she recognized them from her dreams. The woman then turned to staring at Hakuno as though she could not believe her very eyes.

"You...I know you."

Slowly, heads started to turn to the female kitsune still standing at the entrance and exit doors of Ahnenerbe, everyone being puzzled and confused. Even Hakuno turned to have a glance at the newcomer at the door. The figure in question was a young woman with a voluptuous figure and very long blonde hair with matching eyes. She is a woman with delicate facial features and her eyebrows are cut very short and round a symbol of nobility. Her hair is usually tied in a loose ponytail, reaching all the way down to her legs that ends in a spiral, with taut bandages to keep it in place. She usually wears a traditional shrine maiden attire, and over that she wore a white coat held closed by a red ribbon and a golden crown.

"You...you are that girl… the girl who was born of the moon."

Hakuno's eyes widen.

"You're the one who appeared in my dreams. Fighting and dying in endless wars in the world that exists only on the moon".

Hakuno let out a gasp. Who is this person? Just how much does she know? How much does she know? And what did she mean by dreams? Hakuno then tilts her neck to have a better look at the kitsune who was talking about her.

"What in all of the Moon Cell are you?", asked Hakuno.

Suddenly, Hakuno found herself being hugged tight by the adult kitsune who was crying for some reason.

"You're alive. Thank Kami you are alive. How did you survive? I thought you have died on the moon… Kaminashi Hakuno."

The seemingly emotional scene has left the Gremory peerage and Kunou confused.

"Yasaka, what is the meaning of this? How on Earth do you even know this girl's name? We have only just met her," asked Rias.

[FGO OST - Emergency]

Before Hakuno could even say anything, someone grabbed her away from the tight hug of Yasaka.

"Get your hands off my Master! I won't let a youkai like take her away!"

It was Lancer Tamamo, her face serious as she had grabbed Hakuno and placed her into the arms of Caster Tamamo to whisk her away to safety on the side. Lancer Tamamo then thrusted her beach umbrella at Yasaka to impale her with it. Her umbrella was rebuffed by a sword block from Kiba, but he was soon targeted by Nero who also got out her sword "Aestus Estus: The Original Flame". Devil Xenovia stood up to back up Kiba but was soon engaged in a sword fight with Umu Bride. Soon a full-on brawl has broken out between Hakuno's Servants and Rias' peerage and Yasaka's bodyguards. Yasaka had turned into a smaller version of her nine-tail fox form, but she was soon engaged by both Lancer and Caster Tamamo-no-Mae and Tamamo Vitch. Yasaka was losing control overself for reasons unknown as she engages three of Tamamo Nine, her powers dangerously going out of control in the presence of the Tamamo spirits. Hakuno shrieked as she was almost hit by a magical blast.

"WHOEVER MAKES HAKUNO CRY IS BAD CIVILIZATION!", screamed Altera as she charges out downstairs from one of the upper floors of Ahnenerbe into the restaurant floor with her Photon Ray in hand, dangerously charging up to full power.

Hans looked at the scene unraveling before him as he uttered "Oh Shit" as Ko-Gil quickly deployed his Chains attempting to restrain Altera before she unleashed her Noble Phantasm inside the restaurant.

"Hakuno! Use a Command Spell to stop Altera now! Before she destroyed the entire restaurant and us with it!", yelled Hans as Archer EMIYA and Tamamo Cat then busted through the kitchen doors to save Hakuno from whatever danger was going on.

Tamamo Cat joined her fellow Tamamo Spirits in battling Yasaka's small nine-tailed fox form as Archer EMIYA rushed to Hakuno's side and got her to safety inside the kitchen. Caster Tamamo by this point was going full out, now decked in her 4th stage ascension art appearance as she readies her own Noble Phantasm against Yasaka, Eightfold Blessings of Amaterasu on the Weight Stone under the Sunlit Watery Heavens. The mirror materialized in Caster Tamamo's hand and Yasaka's eyes widened seeing the mirror. The energies of Amaterasu are stirring up inside her now, more active than ever before. Yasaka wasn't even sure that she could control herself any more in the presence of that mirror. At this point anything can happen. However, a certain gold blonde has become irritated by such chaos and anarchy that ensued in Ahnenerbe and decided to step in.

"ENOUGH!"

The Chains of Heaven were fully deployed as Gilgamesh, Ko-Gil, and Enkidu sought to restrain everyone. Both Servants, Devils, and Youkai had been fully restrained. Hakuno then came out of the kitchen with Archer EMIYA and Demiya by her side. When both sides seemed to have calmed down, Hakuno notions to Gilgamesh, Ko-Gil, and Enkidu to release them which they did. As everyone gathered themselves Hakuno made her way towards Yasaka. A hushed mood washed over the DxD canon cast as Hakuno looked at Yasaka with both Lancer and Caster Tamamo-no-Mae, Vitch, and Cat joining her side as she asked the youkai leader a few questions.

"Who are you? How do you know my name? What do you know about me? And why do you possess nine fox tails? There is only one one I know of that can possess that many tails and she has cut them off a long time ago."

AN: And thus concludes the chapter. I wonder if it is a bit far fetched to connect Hakunon and Yasaka together. I haven't even thought up of how Yasaka could possibly even dream of Hakuno and her time in the Moon Cell HGWs. Even I am unsure myself what kind of love does Yaska really have for Hakunon - romantic or motherly? Though just because Yasaka dreams of Hakunon doesn't mean she knows everything despite how vivid the dreams may be. What do you guys think? Does such a scenario make sense? Is it even possible? Or am I linking two characters that has no real connection to each other? BTW how is my depiction of Hakunon?

To those who left reviews, I thank you and appreciate it. As expected, Gudako as Beast V stole the show even though I set up the stage for the grand arrival and debut of Demi-Servant Saber Xenovia. It is a bit sad seeing as very few reviews make mention of her Servant profile which was no easy task for me to put together. Makes me wonder if it is worth getting around to drafting a Servant profile for Serafall which will surely be harder to do than for Xenovia's. What do you think of Saber Xenovia disguising herself slightly to prevent revealing her true identity to DxD canon cast? BTW Saber Xenoiva's disguise resembles Ciel's remake art drawn by Takeuchi Takashi. Does the Ciel appearance look good on Xenovia?

For the question of a chapter for "Servant Serafall (?)" to the reviewers...I sort of have something in mind for her. Her scenario is inspired by the story of Arthur Pendragon's trail quest in FGO, so it should be emotionally moving and tear-jerking as one would watch her suffer in her journey trying to look for and reunite with the one she loves. Her journey is certainly harsh as there are forces and factors at play preventing her reunion with her beloved. A certain actor does not want her to be with her beloved and works to keep her away from her beloved (a clue - this antagonist character is from Arthurian legend and is one who has not appeared in FGO although this person has appeared in other Nasuverse works before).

The scenario will take place before Chaldea enters the DxD "canon-verse" Singularity, but will not involve her beloved who is also a Master of Chaldea. Like all trial quests in FGO, it is Ritsuka/Gudako who will test out the Servants with their trial quests in some isolated miniature Singularity. Ambitious as my muses are with this scenario, my writings might unfortunately fall short as I'm not that talented as a writer. I can only give my best to do the scenario the justice I want it depicted. I have an idea of how the scenario would go but I have yet to come up with details. However, I leave this one clue. A list of possible OST that will guide how the Serafall trial quest will proceed and conclude. The names of the OST aren't the clues themselves of course, it is the music themselves that provide you curious readers and Serafall fans how the scenario will go. This list of OST is what I have in mind now and is thus subject to change upon release of the actual Serafall trail quest chapter. Almost all of the OST came from FGO with the exception of one particular OST that was so beautiful and heart-movingly perfect that I had to put it in.
