Chapter 2 - Two Girls, One Tiger
Emiya Residence, Fuyuki City - Main Fate World - The morning after the end of the previous chapter, Six Days before Rin Tohsaka summons her servant
(Jeanne d'Arc Alter/SI's P.O.V)
Waking up in the spare bedroom Shirou provided me is a strangely novel experience if I am being frank, even as I groan while slowly slipping out of the futon bed and standing up so that I can gather my bearings momentarily.
"Seems that this whole thing wasn't some weird dream Merlin came up with as a joke," I say under my breath as there was a small part of me afraid that it was just some dream and that I would wake up back in Chaldea, worrying that I would fade away from all of history all over again.
At least now I don't have to worry about disappearing thanks to being fully incarnated, with all my servant capabilities intact along with a few unique upgrades thanks to the Company involved in making the Waifu Catalog, such as being able to switch to my Summer Berserker form at will.
Relief at not being at risk of fading away as little more than an ephemeral dream aside, I use my shroud of power to form into my Shinjuku casual attire and just take a moment to admire the work of the shroud for a moment.
"I think any uppity magus worth their salt would probably foam at the mouth when they realize what this thing is capable of…" I say with a smirk after finishing my impromptu inspection of the shroud's recreation of my Shinjuku outfit, could try having it recreate that nice violet dress I had on back then too, back when I danced with Master Gudako…
Shaking my head for the moment to clear away the memories for the time being, I walked out of my bedroom and started walking toward the living room to get some breakfast, soon the smell of food came flowing through the doorway as I spotted Shirou placing down several places on the table.
"Good Morning Romee-san," Shirou says with a smile as she gestures for me to take a seat at the small table, my eyes notice some movement in the Kitchen before my eyes widen ever so slightly at seeing none other than Sakura Matou currently doing some cooking in plain view.
Thankfully neither the violet-haired young woman nor Shirou herself noticed the slight shift in my demeanor but either way I calmly took the offered seat and glanced down at the food on my plate, the food in question being some portions of sushi.
"So how was your sleep Romee-san if I may ask?" Shirou asks politely, my focus turning to the redheaded young woman in front of me as she takes a seat opposite me, allowing me to redirect my thoughts towards answering the question rather than the violet-haired Matou in the room with us.
"Eh, it was fairly decent although that's probably just me trying to adjust to a futon rather than a European style of bedding," I say in response, shrugging my shoulders as I begin to eat the breakfast sushi although it takes me a few moments to figure out chopsticks properly.
A user of chopsticks, my past life was not indeed…
Shirou seemed slightly amused at me fumbling to try and properly use chopsticks before she began to eat her breakfast sushi, with Sakura Matou soon joining us with a gentle smile on her face before she turned to face me.
"Hello Romee-san, my name is Matou Sakura, I'm pleased to meet you," Sakura says with a polite smile as I am struggling not to think of the things that she is capable of in a particular version of events here in Fuyuki, not to mention the things ALREADY done to her in the first place.
"Likewise Matou-san, Jeanne Romee, or I suppose it's Romee Jeanne here in Japan," I say while giving the violet-haired girl a smile of my own. However, I am admittedly struggling to hold back my emotions. I think the only reason that I am not right now burning with anger and fury like I usually am is my maxed-out stress defense ensuring that my nature as an [Avenger] Class Servant isn't affected me like it would normally…
Despite that though I know that the moment that I have a chance, I will be bringing Sakura out of that shithole of a mansion and burning the entire place to the ground with absolutely zero regrets about doing so as the fucking place needs to be condemned by hellfire as soon as possible.
"So Shirou-senpai told me that you're here as a part of some unresolved business involving her father, is that right Romee-san?" Sakura asks as her question breaks me out of my dark internal thoughts regarding Sakura's own home life, allowing me to return to the moment and give an affirmative nod.
"Y-yes, I'll be spending a month or so here in Fuyuki to try and put it all to rest once and for all and be able to leave the city with all parties involved satisfied," I say in response, with the violet-haired Matou girl staring at me for a few moments before giving a nod of her own in response.
I glance down at my right hand momentarily where the command seals are and try to consciously keep them out of sight for the time being, even if it ends up being fruitless in the end I do want to at least try to keep Sakura unaware as long as possible.
It's only then that I notice that the final, fourth plate is unattended and just as I realize who that is four I hear a moped bike suddenly break at the front of the Emiya residence as a pair of feet are rushing up the path to the household.
As the door soon opens, I can only mentally count down to the moment that she appears in the room, something that I believe Shirou is also doing herself as neither of us got the chance to let her know that I was here in the first place as eventually….
"SHHIIIIRROUU!"
That is the first thing everyone in the living room hears as a young woman with short light brown hair enters the room, her equally brown eyes alight as she spots Shirou and Sakura and regards them with a bright, energetic smile before seeing the unattended food plate and immediately goes to start eating the food.
This is Taiga Fujimura, the supposed guardian of Shirou Emiya here in Fuyuki and the grandaughter of Raiga Fujimura who is the head of a yakuza group here in the city, but in a way, she acts more akin to a freeloader more than anything in my opinion.
"Morning Fuji-nee," Shirou Says with an exasperated smile, the older woman has been coming here since her father died many years ago when she was still just a child and has acted as the guardian of the redhead ever since that day.
Midway through her breakfast, Taiga notices that there is a new occupant in the household, that being myself and looks right at me with a wary glint in her eyes, having not been informed of my presence in the house before this point and is quick to open her mouth.
"Shirou why is there a foreign girl here in your house?"Tiger asks inquisitively casting wary glances my way while turning to face the redhead, soon enough Shirou is able to give her a satisfactory answer by explaining that my presence here in the household is because of my supposed relation to Shirou's adopted father through his mercenary work.
"I see, so she won't be staying too long then?" Tiger asks having been mollified by the excuse and is now curious how long my stay in the household will be, mostly so that she knows how long I'll be hanging around for in her mind.
"Roughly a month maybe two depending on how the unresolved business plans out for all involved parties" I respond as I finish eating the provided breakfast, quite frankly it was an interesting thing to eat for breakfast as I am more used to eating more European style of breakfast foods such as hash browns and toast.
"I see what is your name then Miss Foreigner" Taiga asks as she continues to wolf down breakfast all the faster as she notices the time, amusement fills me as I watch her empty her place at a rate that I think she'll probably get a stomach ache.
"Jeanne Romee, or here in Japan I suppose it's Romee Jeanne" I respond having two effectively say the same thing that I told Sakura just a short while feeling the earlier amusement grow as she soon gets up after making her plate practically spotless.
"Alright then but I'm warning you better not do anything to harm Shirou while you're under her roof, am I clear Romee-san?" Taiga says as tries to act as the concerned guardian which is admittedly hard to portray when she has just a small amount of rice on the edge of her lips that ruins it just ever so slightly.
"Sure sure, I would never think to harm her, especially since her father had saved mine years ago" I respond with a very casual tone to the seemingly very real threat if I were just a mere foreigner in the first place, rather than the [Avenger] Class Servant that I am.
Tiger says me down with an almost searching look as if trying to see any dishonesty who might gaze and when eventually she finds none, she gives a satisfied nod before she has to leave, rushing out the door as she waves goodbye to both Shirou and Sakura to get to her a moped bike so she can get to school on time.
It is not long after this point that Sakura also leaves so that she to get to the school before Shirou so she can prepare herself for archery club later in the day, saying goodbye to her redheaded senpai as she leaves and hopes to see her at school shortly…
With the two of us alone it's now safe to talk in private about our plans moving forward, particularly concerning the rapidly approaching Fifth Holy Grail War since it is a major looming threat that the two of us need to deal with as a team.
"So Shirou, have you thought much about what we had spoken of yesterday at all?" I ask Shirou with a casual smirk on my face, the smile that was previously on Shirou's face falling as she has a somewhat conflicted look on her face.
"I have Romee-san, specifically I wanted to ask how we are supposed to summon a servant exactly?" Shirou asks as I take a moment to think about how I want to go about explaining to the redhead the details of summoning a servant without just giving away the fact I know her workshop has a summoning circle already.
"I'll explain that shortly because I wanted to verify something first, particularly about your method of activating your magical circuits," I say, memories of a past life reminding me of just complete and utter merde(Shit) Shirou's method of using her magus abilities is, especially since having a proper set of magical circuits are fairly vital in trying to reliably sustain a servant.
"What do you mean by that Romee-san?" Shirou asks curiously as it's clear that as far as she's aware her method of using her nerves as makeshift magical circuits is perfectly normal and not the painful and almost flat-out suicidal it truly is…
"Tell me Emiya-san, do you recall your father ever taking you aside to unlock your magical circuits?" I ask the redheaded young woman who looks rather confused as to what I mean by that question, resulting in me making an exasperated sigh as if I didn't already know this way ahead of time.
"Emiya-san please be honest with me when I ask you this, are you using your nerves to create makeshift magical circuits?" I ask while trying to emphasize the importance of this question, the way I worded the question seems to make Shirou question her method for perhaps the first time in a very long time.
"Am I right in assuming that's not normal Romee-san?" Shirou asks after a moment of hesitation, indirectly confirming that yes, she is indeed using her nerves as makeshift magical circuits, while I do know about this ahead of time, I can't help but still feel frustrated nonetheless.
Especially since she still reminds me so much of my old master…
"Correct Emiya-san, it's one the most dangerous and self-harming methods of forming magical circuits possible, and quite frankly it's not even necessary since you should already have a set within you, probably atrophied by the years of disuse.." I say while letting a small amount of my distaste for the practice leak into my tone of voice, Shirou for her part in all of this wincing at the fact that not only had she been doing something incredibly dangerous for years, but also the fact that it wasn't the correct way of using her magical circuits in the first place.
"So how do I go about awakening the magical circuits that I have then Miss Romee?" Shirou asks after taking a moment to clear her mind of the fact she was basically using the wrong method of creating magical circuits for years and get back to the matter at hand, wanting to know her options if there are any…
"Well, there are two methods available to you right now if I am being honest, both being something I could do right now at that," I say as I slowly stand up and walk over to Shirou's end of the table with a smirk on my face, finally being able to pose an offer that I have been hoping to do since I got here.
"The first is that I run a small amount of my own mana to forcefully awaken your magical circuits, the process would be of course excruciatingly painful and would likely render you knocked out for the entire day as a result," I say casually as if the fact that Shirou's screams of pain would be something I'm perfectly fine with hearing.
"And the second option?" Shirou asks in a matter-of-fact tone, watching me stride over toward her before letting my shroud of power show itself to Shirou Emiya herself, her eyes widening as she looks at the basic red shroud in a slight amount of awe.
"This is my family's mystic code of sorts, it can grant me the power akin to a weaker servant, can change into whatever clothing I allow it to integrate into it, fix any defects with your body, which includes your atrophied magical circuits, and the best part is that it can generate a copy of itself onto another person so long as they willingly accept it," I say as Shirou does genuinely seem interested in the shroud far more than the first method but it is clear that there is some hesitation on the redhead's part to agree to the second method.
"It seems like it has so many benefits, there has to be a catch of some sort right?" Shirou asks to which I nod my head, mostly because I figure it would be in my best interest to be as transparent as possible with this if I am to get Shirou to agree to essentially being made a part of my retinue…
"There are two main drawbacks, the first is that once you are connected via this mystic code Emiya-san, there is no going back as it is a permanent arrangement that truthfully benefits you greatly," I say while holding up one finger to indicate that this is the first drawback that I reveal to Shirou who nods and waits for me to explain the second drawback, although I don't sense any increased hesitation from the redhead.
"And the second drawback is that you would effectively be agreeing to be a part of my family so to speak, becoming forever bound to share our fates together, like a family would," I say as I give her the second drawback, this time I get a visible reaction from Shirou as her eyes widen in shock as that is admittedly a pretty big ask if I were in her shoes.
Who am I kidding, she'll probably reject the idea outrigh–
"I…I'll agree to have the shroud Romee-san" Shirou says, determined with a very faint blush on her face as my brain stops midway through my thought process, my mind needing several long seconds to reboot essentially…
"I…are you sure Emiya-san, are you truly ok with going through with accepting my family's mystic code despite the fact it would mean becoming a part of my family?" I ask as I am mentally struggling to try to regain control of the situation as part of me was admittedly thinking she wouldn't agree to the second method considering I wasn't kidding about this being a permanent arrangement.
"Of course Romee-san, if through accepting the shroud I can get the strength I need to prevent another Fuyuki grail war, I'm willing to accept the consequences no matter what they are," Shirou says with a determined smile, my eyes widening as for a moment I don't see Shirou Emiya in front of me
It's Jeanne d'Arc I see in her place, the original pure one…
Resisting the urge to let out an extremely frustrated sigh at the fact that the woman in front of me is practically going to end up a modern-day version of her, especially since I know of her future incarnation making a deal with the fucking Counter-Force, if I do nothing to try and deal with the mile-wide hero and martyr complex she has, I finally relent and allow my shroud of power to start elongating and begin to wrap around Shirou…
As Shirou looks at the shroud beginning to wrap around her, she doesn't resist the pull of the shroud as it soon completely covers her entire body and before long, I feel the connection to the newest member of my retinue form, making me roughly 24 credits richer.
But the mere instant after the binding is complete, I can hear Shirou hold her head in pain with her right hand while grasping at her right arm with her left as I sense her magical circuits forcefully activate all along her body for a split second, looking like she's about to break down before [Stress Defense] starts to kick in HARD to help her handle the influx of new information flowing into her head among other things.
Before long the redhead comes out of the binding sweating a ton as she breathes heavily from the exertion of the sudden download of a ton of her skills from all of her various routes into her very being, making this Emiya Shirou a unique combination of all three variants of herself at once…
With the basic red shroud now wrapped around her body and integrating into her clothes, Shirou looks dead at me with so many questions running through her head right now due to all the new information she is still trying to process but the one she decides to vocalize is…
"Your father and my father never meet did they Jeanne…?" Shirou asks knowingly, likely having been clued into who I truly am as I chuckle and give the redhead in front of me a sardonic smirk as I allow my own shroud of power shift from my Shinjuku casual attire to my full servant armor while retrieving my flag and blade from my pocket space.
"Not unless your father was a time-traveler Shirou, thus allow me to properly introduce myself for real-time….. I am the [Avenger] class Incarnated servant, Jeanne d'Arc Alter~" I say as a dark grin shows on my face as I am finally, finally able to reveal my true nature to someone in this damn city!
Shirou looks at me with wide eyes before she chuckles and mumbles something about having a servant living under her roof the whole time and not even realizing it before shaking her head, finally calming down enough to inspect her cloak more thoroughly.
"I see what you mean by this being a permanent arrangement Jeanne, although were you expecting me to suddenly receive a ton of abilities from my other selves or was that just an accident?" Shirou asks out of curiosity, to which I nod and give a small explanation about how upon bringing in someone into my retinue, they gain any skills that they're missing although I do admit I am unaware exactly how that is achieved.
"So I assume you want me to summon Saber like normal, but what exactly are you hoping to summon if I may ask Jeanne?" Shirou asks as I take a moment to recall what my past self had in mind for getting a servant…
"Normally only the [Archer] and [Saber] class would be available due to [Rider], [Lancer], and [Assassin] already being summoned but I think I can still summon an [Assassin] class for myself," I say as I recall how in the Heaven's Feel route, Zouken Matou was able to summon a second [Assassin] despite one already existing due to the irregular nature of Sasaki Kojirou's summoning.
Meaning if I am right, I should not only be able to summon a servant as a servant myself but also deny Zouken the chance of an additional servant to aid him when it comes time to burn him and his bug nest to the ground.
I see Shirou looking at me confused as to why I am so confident regarding my chances of summoning [Assassin], so I end up diving into a small explanation of how the current [Assassin] servant is an aberration, a servant that shouldn't have been summoned but due to Caster effectively cheating, she got Sasaki Kojirou as an irregular [Assassin] class servant while still technically leaving the spot open for anyone who knew the system well enough.
With Shirou's curiosity now satisfied, it's only at that moment that the redhead looks at the clock in the room and realizes that she'll be late for school if she doesn't move fast. Because of that fact, she makes use of her new shroud to grab all the empty plates to wash them all up and once she's done Shirou turns her head to me as her shroud fades into her clothes and is soon completely hidden from sight.
"We'll talk more about our plans to summon our servants after I'm back from school, in the meantime I need you to clear up my workshop so that it's ready, Is that alright with you Jeanne?" Shirou asks as I nod in agreement to her request, having already intended to do so anyway as I know I'll need to check my company phone for a proper summoning chant while the redhead is away at school.
While Saber's summoning in the Fifth Holy Grail War was attained by pure accident and coincidence while also being done without a summoning chant, it did result in deficiencies in her pact between her and Shirou as a result and potentially even lowered stats due to the subpar nature of the summoning itself.
While that last fact I am not too sure about the authenticity behind, I am not reckless enough to take a chance on that front if it's what truly happened as while there is a chance the shroud would fix the issues of an improper summoning, it's better to get it right the first time in this instance.
"Alright then, I'll unlock the shed on my way out so you can go in, see you when I get back this afternoon Jeanne!" Shirou says while leaving the house, briefly walking over to the shed to unlock it before rushing out the gate to head to Homurahara High School.
Once Shirou is gone I allow my shroud of power to shift my servant armor back into my Shinjuku casual attire and go to check out the shed, mostly to see how much space we have to work with and to check on the magical circle in the shed.
It's only when I see the number of boxes that are stacked in the location which I am assuming the circle is in and just sigh as this is going to take me a while if I don't want to risk disturbing the magical circle itself….
"This is gonna be a real chore," I say with a look of annoyance but in the end, I allowed my shroud to manifest once again while inside the shed and began to use it to help me move multiple boxes at once.
All the while I have one shroud cloth tendril reach into my pocket space to retrieve my company phone, if only to allow me the ability to start checking all the possible variants of the Grail War servant summoning chant while I am moving the boxes, just so I have the time to memorize the one that suits the situation.
Mostly because there is one particular [Assassin] above all else that I desire to summon, after all, she served my master Gudako quite well in that Camelot singularity…
Shirou's Shed workshop, Emiya Residence - Hours later
(Jeanne d'Arc Alter/SI's P.O.V)
"Fucking hell, how is it that after hours of searching for one single alteration to the summoning chant, all I can find is the one for [Berzerker]?!" I scream out in pure frustration, nearly throwing my company phone in a rage out the door but just barely keep my anger in check to not throw out the advanced technological smartphone that should not exist in 2004 into Shirou's garden.
There are probably dozen upon dozen of Zouken Matou possession contractors out there in the wider multiverse yet not a single fucking one wants to give a detailed description of how to modify the summoning chant to get the desired class.
I think I have a new reason to hate Zouken Matou as if I didn't already see the shitty old bastard in the worst light possible as it is in the first place, now I hate him for the simple fact the contractor versions of the man don't even have the decency to publish their shit online!
Yes, I know that this is a very illogical thing to hate a bastard like Zouken Matou for, and no, I don't give a fuck that this new additional reason for hating the old wormy fuck is extremely petty…
Putting my utter disdain for the old worm aside for the moment I decided to check the time and see that Shirou should be heading back home right about now, assuming she isn't busy being the repair girl of her school again at least, and considering that there is a chance that Taiga might show up soon, I think it would probably be best that if I decide to try and attempt to summon assassin now.
Still, it's not like my search for a summoning chant was entirely fruitless as I did learn that some contractors believe that simply announcing the title of Hassan would be enough to draw out the true [Assassin] as well as using the specific name of the Hassan desired to almost guarantee the desired Hassan to be brought forth.
As such I decided to add something to the standard grail summoning, a new line that I've come up with that should hopefully work and if it doesn't then I'll have to accept the fact I'm gonna be either taking Saber from under Shirou or risk working with the tanned bastard archer for the foreseeable future.
So fingers crossed that this works…
I take a deep breath and stare down at the summoning circle below my feet, reaching my hand out toward it as I begin to draw on the mana within my command seals, the red etchings upon my right hand glowing as the circle begins to glow a brilliant bright blue as I began reciting the slightly modified incantation…
For elements silver and iron,
Foundation stone and archduke of pacts,
And for my Great Master Schweinorg.
Close the four gates.
Come forth from the Crown and follow the Forked Road leading to the Kingdom.
Fill,
Fill,
Fill,
Fill,
Fill.
Repeat Five times but when each is filled destroy it.
Set.
Heed my words, my will creates your body, and your sword creates my destiny.
If you heed the Grail Call and obey my will and reason then answer me.
I hereby swear that I shall be all the good in the world.
That I shall defeat all Evil in the world.
Seventh Heaven clad in the Great Words of Power.
From the Binding Circle vow Guardian of the Scales.
My knife shrouded in shadows, you who bear the title of Hassan of Serenity, be the one who brings the gift of death to my foes.
What happens next is a surge of mana from the summoning circle as it glows so bright that I am momentarily blinded before I finally manage to open my eyes once more and see a beautiful young woman kneeling before me, with short violet hair behind a pale white bone mask, the mask of a Hassan…
"Servant [Assassin], I have answered your direct summons made upon the Holy Grail, I shall be your knife in the dark Master," The woman says as she slowly stands up before looking up at me as if she's greatly confused at what she's seeing, likely noticing my nature as a servant yet also recognizing the fact I'm her master at the same time.
"Well well, didn't think it would actually work but thank fuck it did as I was worrying I was gonna have to deal with [Saber] or [Archer]~!" I say with a downright ecstatic grin on my face as I rush over before the violet-haired young woman has a chance to react and bring her into a one-arm hug with my command seals visible in front of her.
The sudden hug out of nowhere makes the woman freeze up slightly as she looks down at my command seals and seems to expect something to happen, but nothing does as seconds tick on by with her expression changing from resignation to a growing, building feeling of desperate hope.
"Oh didn't I tell ya, I'm practically immune to all forms of diseases or poisons so by all means, you don't have to worry about me dying from giving you a hug Serenity," I say with a smug smirk on my face before that same smirk disappears into an expression of shock and concern as the [Assassin] Class servant does something I never in a million years expected an Hassan to do…
Serenity begins to tear up as it finally dawns on her that her one wish, to have a master that she could touch and potentially even love without killing them is granted to her, the violet-haired girl's arms wrapping around my waist as she just lets out tears of pure joy and happiness.
While I am rather uncomfortable by the sudden tender moment that I admittedly did spring on her, I'm not heartless enough to ruin the moment and just hug her back which only further induces tears of happiness from the [Assassin] class servant.
I guess deep down I am still the same Jeanne d'Arc, even if I'm not the original one if I can still feel this warmth from seeing someone feel happiness as a result of my own actions, a compassion that is part of the saint that I was made from.
This warmth I feel, it's different from the burning rage that I felt so many times before in a good way…
Author's Notes
Chapter 2 of Fate Saint Alter is FINALLY finished, it took me way longer than I had intended, mostly because I had to do a lot of fine-tooth comb levels of research, and beat down a bunch of delays with other story chapters while also dealing with writer's blocks.
If I am being honest, there is part of me that still thinks that there is going to be either something that I missed or something I got wrong (Which I probably have somewhere) just because of how enormous this fandom truly is…
Still can't help but love FATE as a whole, despite the sheer size and depth of the lore behind it and its various timelines!
Now then today I'll be going for Two Plot point discussions, which are….
Capture of Fem!Shirou
This was always going to be probably the very first one on the list because who doesn't want Shirou Emiya on their side, especially once the company skill download gives them all of their various skills while fixing up their body's various deficiencies.
That being said though, this Shirou has become something of a combination of the various versions of Shirou Emiya throughout the Fate Multiverse, which is why [Stress Defence] kicked in hard to help her handle the sheer enormity of all her alternate selves.
It is admittedly going to take Shirou some time to get used to all of her new abilities now that she has them, although I am unsure if I should include the stuff she would get from Archer's arm from Heaven's feel or not due to the grey area that represents with the waifu catalog.
I'll follow up on that with those who might know better and figure out the answer to that grey area…
The Summoning of Hassan of Serenity
Now I know what many of you are likely thinking, [Assassin] already probably exists in the grail war by this point in time…
Here is the thing about Caster's version of [Assassin], it's not the intended servant to be summoned in the first place that she was able to summon whether through some loop hole or through some manipulation of the greater grail itself I am not 100% sure.
Either way, it would explain how we briefly got two [Assassin] Servants at the same time in Heaven's Feel, especially with Zouken being a founder who probably knew of this factor and took advantage of it in that route.
Of course, it also helps Jeanne that she got her Command Seals from outside the Fuyuki Grail system which is likely making an already broken system even more broken, maybe we'll see future consequences for this~?
So why Serenity then?
First of all Old Man of the Mountain Hassan is immediately out of the picture, even though Jeanne likely knows of him as his summoning is unique.
Next Hassan of the Cursed Arm is off the list because of the fact Jeanne knows of his role here in the Heaven's Feel Route and she's not exactly willing to be in the company of the man who would willingly join Zouken Matou.
While Hassan of hundred personas was a possible idea, she's already been summoned in the prior Fuyuki grail war so that option is immediately out…
In the end, Serenity is probably the best choice in the long run, not to mention the poor girl really is touch-starved and with Jeanne having Maxed out [Body Defence] which gives her immunity to all forms of Diseases and Poisons, she's practically the perfect master for the most poisonous Hassan of them all who desires above all else, a master that does not die to her touch.
Now then, Next time on Fate Saint Alter: Shirou returns home, The King of Knights appears, and War Preparations!
See you all next month hopefully!
