Rin and Sakura had spoken while I was unconscious, and reached an understanding of a sort — at the least, a tacit agreement not to broach the more intimate issues that had yet to be resolved between them; to put these off till later, when things were properly settled to a stable status quo.
Before that, though, there were a number of practical concerns that needed to be addressed. Thus, the Saturday the weekend subsequent the War — after the girls had finally gotten over the novelty of my new body — Rin decided to call a formal-informal debrief. Voicing an utter lack of interest, Illya had for the afternoon departed with her maids to assess the damage the War had wrought upon the Einzbern property. As Rider had likewise seen no need for her presence, it was in the end just myself and Sakura in attendance.
"So, this is it, hm?" asked Rin — seated across the table from me and Sakura, looking upon the artifact that rested before her. "The sheath of the Excalibur? I have to say, Lord Animusphere was really underselling it when he told me what to expect. The weight of Mystery is physically palpable."
Apparently, Avalon might've served as a catalyst to the summoning of Arthur Pendragon; but on account of the tampering of True Caster, the Formalcraft array chalked upon the floor of my storehouse had brought forth Astolfo as the Saber of the War instead. Hearing of this, I was vaguely relieved that I hadn't had to accommodate a legend so intimidating as the Once and Future King on my limited means.
Of course, Astolfo was prior his staining quite the headache as well, if for different reasons. He'd synergized far too well with Fuji-nee; and whenever the two of them were simultaneously present, it felt as if my sanity were on the verge of evaporation.
... I'd miss him, for all that he was frequently insufferable — girlishly flirting with me in Mount Miyama, in front of shopkeepers that knew me by name. I wondered if it would amuse him that my body was now objectively more feminine than his had ever been.
"... it would be irresponsible of us to keep it around where it could be stolen and misused," said Rin, "but I'm not certain that there's anyone trustworthy enough to take it off our hands. Lord Animusphere specifically recommended against the Clock Tower, and didn't want it for himself. In that case, maybe we can contact the Church ... ?"
"If it's a problem, I can just put it back inside me for the time being," I offered.
Rin visibly winced.
"That sounds incredibly wrong," she said. "But, putting that aside — considering the effect that the sheath's already had on you, I really don't think it's a good idea to further expose yourself to its influence."
"I agree with Nee-san, Senpai," said Sakura, chipping in. "So long as we all stay vigilant, there shouldn't be a need for that."
Personally, I didn't have the sense that Avalon would continue to act on me without a regenerative, defensive capacity; but for Sakura's peace of mind, I clarified:
"I meant that without activating it, I can stow it away until we find a place to dispose of it," I said. "For the past week, I've just been keeping it in inventory."
Sakura blinked.
"You can just summon things out at will?" she asked. "That's a lot more convenient than my Shadows ..."
"We can talk shop later if needed," said Rin, "but if you're certain that you won't be affected, I'll leave it to you until we figure out something more permanent. Switching gears for a bit —"
With purpose, she turned to Sakura, very intentionally meeting her gaze.
"I understand that it isn't something you want to hear, Sakura," she said, "but ... even though I can't agree with his decision, Father truly did have the best of intentions in fostering you to the House of Matou."
Sakura looked ready to interrupt, but seemed to calm as I grasped her hand beneath the table in reassurance.
"What I'm saying is," Rin continued, "he felt that you were far too naturally endowed with thaumaturgical talent. If left as you were without a Crest — without training as an heir — you would've been defenseless before the more unscrupulous elements of the thaumaturgical community. I'm not saying the way that Father went about this was the best. It's just that the threat posed by other magi isn't something that we can wave off even now."
"But I'm already perfectly capable of defending myself," said Sakura. "I'm not certain where you're going with this?"
Removed of Angra Mainyu's influence, Sakura had nevertheless retained the instinctive ability to manipulate Imaginary Numbers — earlier in the week, demonstrating to me her skill fabricating tiny shadow creatures to act as her familiars. She was hesitant to recreate the large one that we'd engaged later on in the War — but if push came to shove, I was confident that she could reasonably ward off the majority of conventional opponents.
"That besides," I said, "if I'm aware of a potential threat, I wouldn't leave Sakura to defend herself alone."
Rin frowned.
"Nonsensical combat performance notwithstanding," she said, "the two of you are hardly omnipotent. If the Clock Tower were to issue a Sealing Designation to either of you, you'd be up against the resources of a vast organization for an indefinite period of time. At some point, you'd have to rest — and that's all the opening they would need."
She shook her head.
"No," she continued. "The best defense would be to altogether preempt the existence of a threat. Outside of standard policies enforcement — unlikely a problem, provided that we go about things carefully — the usual justification that the Clock Tower employs in issuing a Sealing Designation is a reasonable certainty that a highly unique Mystery is beyond inheritance or replication. This wouldn't be a concern to magi of generic stock, but for Sakura ... Without a Crest of Makiri to communicate your abilities to an heir, you'd be flagged for Sealing the moment anyone catches wind of your Shadows.
"That's why I'll be constructing a Crest for you — so that you pass on your Mysteries when you eventually have a child."
My knowledge in matters without the mundane had significantly expanded as of the conclusion of the War — if mostly in relevance to items pertinent to my composition. Absent of directly accessing the Clairvoyance of Verg Avesta, though, I was still very much unfamiliar with the cultural practices of thaumaturgical society.
"Isn't that kinda, like, difficult?" I said.
Tohsaka nodded.
"Normally, it would be," she said. "A Crest is generally anchored to the spiritual quintessence of some fragment of a Phantasmal creature, transplanted to the soul of a magus. However — do you recall what I said about Crests the last time we discussed them?"
Thinking back, I put a finger to my lips.
"That they're a bit like a Curse that's passed down through a bloodline?" I asked.
"Yes," Rin replied, "and in lot of ways, that's literal. It isn't a common practice anymore, but there was once a tradition amongst the Russian Kabbalists to bind the inheritance of Mystery to a genetically communicable Curse — the Curse of the Grand Order. The transplanted Crest would in essence merely become a shibboleth to unlock the function of the Curse."
"I see ... ?"
I didn't, really — but Tohsaka's habit was to sum things up in an easily comprehensible manner once she'd had her fill of rambling. If we just humored her a bit more, she'd eventually get to the point.
"As Curses aren't my area of expertise," Rin continued, "actually going about this would take a bit of research. Thankfully, rather than developing from scratch, I would only need to adapt an existing Curse for the task — and there's one sitting right in front of me."
Ah.
"What are you talking about, Nee-san?" asked Sakura.
"You, Emiya Shirou," said Tohsaka, looking to me. "As of now, you're an Incarnated Demon — and Demons are ultimately entities akin to Curses. It's understandable that Sakura isn't interested in living the life of a magus, or training an heir — but if things go as expected, she won't have to. I can just commit the inheritability of her use of Mystery to a Curse of the Grand Order. Your cooperation is the only thing required." She paused. "Or rather, one of the two things that I require."
I could trust that Rin wouldn't go entirely mad scientist on me — putting me on a dissection table like some kind of lab specimen or so forth. I might've now become a Demon, but she wasn't the sort to deny me my dignity as a sentient being. Probably.
"What's the other thing you need?" I asked.
"Babies," said Rin. "At least one. Or, well, actually — preferably one. With an Incarnated Demon on hand — functionally male — the easiest way to commit a Curse to genetic heritability would be for the Demon to father a child."
"Nee-san!" said Sakura, flushing.
"D- Don't take it the wrong way, Sakura," said Rin, slightly stuttering as she waved her hands before her. "I'm not telling you to immediately go at it like rabbits or anything. To begin with, I'd need to devise a way to adjust Emiya-kun for the process — and that's likely to take a couple of years at the very least!"
Deciding to spare Rin the awkwardness of topics best left for another occasion, I said:
"So, if Sakura and I have a kid, I'd also be safe from a sealing designation?"
Rin's lips drew into a line.
"Mm — about that," she said. "I told you that Lord Animusphere intended to 'produce' me as the victor of the War?"
Shortly after I awoke, she'd explained the basics of the agreement that she, Sakura, and Illya had reached with the man. The Master of True Caster, she'd called him. It seemed that he'd participated in the War solely for the purpose of physically dismantling the Greater Grail and extracting the Core for his own use. All three girls had conditionally assented, abdicating claim to their birthright in exchange for favors.
Not that I couldn't understand, really. Sakura and Illya had every reason to want the Grail removed; and Rin wasn't keen on having a potential disaster sitting on her property.
"Yeah?" I asked. "What about it?"
"I'm still not entirely sure that we can trust him," Rin replied, "but — at the end of our negotiations with him, his recommendation for you was to go with a multi-layered fiction."
"Multi-layered?"
"Emiya Shirou died at the end of the War," said Rin. "You're somebody entirely unrelated to him, who I hired to take his place. That's the top-most layer of the lie."
"Okay?" I said. "What's the next?"
"Lord Animusphere's willing to assist in falsifying the outcome of the War. If people arrive in Fuyuki to poke around, any attempts at divining the past would end up confirming that the Grail did in fact grant my wish — recreating you as a kind of thaumaturgical construct bound to Sakura. Ergo, Emiya Shirou died, and wasn't somehow resurrected." She paused. "To properly convince the Association of this — if push comes to shove, you think you could pull off Saber's trick with the bunrei proliferation and the submersion in and out of Imaginary Numbers?"
Emiya Shirou wouldn't have been able to, but the me at present wasn't so restricted.
The Avesta was as a Noble Phantasm nothing less than a perfect record of the World — incapacitated in its satiation to act upon the World without.
As a record equal in fidelity — if comparatively less complete — the Verg Avesta embodied in the Avenger of the 3rd could as of bodies colored in its Primordial Curse reflect a perfect reenactment of outcomes observed.
In contrast, Unlimited Blade Works was a mechanism as to overwrite the World without; to over-paint it in the Otherworldly Common Sense of a Demon. Comprehensiveness and fidelity were reduced per a bias unto melee combat, but phenomena committed to record could be externalized forthright; unadulterated.
By the action of the Ever-Distant Utopia, I could no longer become the Archer of the 5th; the Avenger of the 3rd; the God that was wished for. The records that I now expressed were as yet restricted in comprehensiveness — less on account of Elemental Affinity, and moreso the boundaries inherent my composition. Fidelity was on the other hand no longer compromised; and by the appraisal of the World, there wasn't any distinguishing a reenactment from its original.
To put it simply, I was unalike to Emiya Shirou unrestricted to the Projection of swords; or in the reproduction of a Noble Phantasm, to any penalty of Rank come of fidelity insufficient.
This was only to be expected. Even that in Avenger's use of the Verg Avesta, nothing at all was physically manifest to the World without the coloration of its Curse — so as to perfectly reenact the outcome wrought by a Noble Phantasm, the Noble Phantasm in question had to be perfectly committed to record.
The complete use of Indiscriminate Idol Rampage was well within my grasp.
"I think so, yeah," I said.
"In that case," said Rin, "we'll have the Clock Tower discover that you're a familiar to Sakura. If we publicly establish her command of Imaginary Numbers, it'll be a known quantity that she's able to fabricate familiars at will. More of the same on a larger scale shouldn't be a surprise to anyone."
"Won't the Association suspect that I'm a Demon, though?" I asked. "I assume that they'll have ways to detect Curses."
"Familiars animated by Curses aren't uncommon," said Rin. "Meanwhile, fully Incarnated Demons are so exceedingly rare that certain demonologists have voiced their doubts on the legitimacy of the documented cases. More likely, you'll just be seen as a high-performance golem or homunculus; something akin to a Ghost Liner."
Pretending to be a Servant, hm? That was ... well.
It wasn't unacceptable, as fictions went. I'd never really minded the reputation I'd acquired as 'a Brownie' or 'a Fake Janitor.' Being regarded in the same light as 'a golem' or 'a homunculus' was really just more of the same.
"This Animusphere guy wants the Grail without advertising himself as the victor," I said, "so — I guess it'd eventually be discovered that the Greater Grail somehow evaporated after you made your wish?"
"Something like that, yes," Rin replied
"... given that Kotomine was posted here specifically to act as the Grail's caretaker, wouldn't the Church complain about it? Or the Illya's family, for that matter?"
"I'm on good terms with the Church," said Rin. "They'll let it go — particularly as the Grail was to begin with never actually theirs. As for the Einzberns — Lord Animusphere said that he would go and have a chat with them."
That sounded like the sort of euphemism Fuji-nee's grandfather would use when talking about work.
"Anyways," said Rin. "You're both on-board with the plan?"
Sakura didn't seem entirely happy, but hesitantly nodded — turning to me.
"If Senpai's fine with it," she said, "I'll consent as well, tentatively. Though, I don't really like the idea that the Clock Tower wouldn't regard Senpai as a person ..."
I squeezed her hand.
"I don't have any issue with it," I said. "And it's not as if the opinion of a bunch of politicians informs my sense of self-worth."
Rin nodded.
"I'll begin making arrangements, then," she said. "And while we're on the topic, Emiya-kun — there's also the matter of your new appearance, and what to do about your legal identity."
Reflexively, I looked down to my body.
Short the energy or leisure for a proper shopping trip, Illya and Sakura had made a morning ritual of using me as a dress-up doll. I'd ended up this morning in an older hand-me-down that Sakura had received from Fuji-nee — a button-up dress that was a little tight around the chest.
I'd have liked to just put on my usual sweater and pants, but Sakura had been strangely insistent.
"I don't think it really matters what I look like," I said. "Can't I just pretend to be a maid that you hired from overseas or something? I mean, it's kind of a shame that I wouldn't be able to say goodbye in person to Fuji-nee or her grandfather; but I can probably exchange letters with them, postmarked from overseas."
Closing her eyes and sighing, Rin pinched her brow.
"Do you honestly have zero attachment for your life until this point?" she asked. "Emiya Shirou has a social identity — a standing in the community here in Miyama. If he were to vanish, questions would be asked, and the Fujimura-gumi would move to investigate. That just complicates everything — and we wouldn't be able to obtain the necessary paperwork for your new persona without their scrutiny."
Vanishing outright didn't seem like a terribly complicated solution to me, but it sounded as if Tohsaka already had a plan in mind.
"In that case, what do you propose?" I asked.
"Mental Interference," Rin replied. "Specifically, a Mystic Code that forces people to perceive you as Emiya Shirou. I don't know that it'll necessarily work on Fujimura-sensei, though. She's inconveniently sharp when you least expect it, and once she recovers from her hospitalization ..."
On account of an unspecific something that had transpired in my absence the day that Rin had commandeered her current bedroom, she'd more than once expressed an incredibly high evaluation of Fuji-nee's instinct for Mystery.
Lacking the details, I didn't know if her opinion was entirely warranted; but Fuji-nee had in the decade past never once noticed anything unusual about my work in the storehouse. It was possible that Rin was being paranoid.
Still, working within the confines of her plan ...
"Dad implied before that Fuji-nee's grandfather isn't entirely in the dark with regard to magecraft," I said. "Maybe we could go and speak to him? Have it so that Fuji-nee is present, and just spill the beans. They could probably help us out with relevant paperwork and so forth."
A Mystic Code as to maintain my identity as Emiya Shirou would be immensely useful; but if Rin's suspicions were accurate, and Fuji-nee was likely to see through the ruse — the obvious solution was simply not to keep the Fujimura in the dark.
It'd been on the presumption that the scary magi that enforced the masquerade would otherwise threaten the people that I cared about that I'd for so long kept my magecraft to myself; but it never really sat right that I'd had to keep secrets from Fuji-nee and her grandfather. Now that it had come to light that the individual locally responsible for the masquerade's enforcement happened to be a certain Tohsaka Rin, secrecy didn't seem so urgent a need.
At my proposal, the girl herself seemed skeptical — but relented with a sigh.
"I suppose we'll have to deal with the Fujimura sooner or later," she said, "and it's better that we take the initiative. Though, are you really certain about this? Seeing as we're literally going to be making the case that, yes, humans can in fact completely transform overnight, I'm not sure how you're going to convince them that you're actually Emiya Shirou."
Per my years of experience dealing with the Fujimura, I'd be surprised if they didn't just look at me sympathetically, and tell me that they wouldn't judge my sexuality. That said, we couldn't afford to be overly optimistic.
"Wish for the best, and expect the worst, I guess," I replied.
Hopefully, Fuji-nee's grandfather knew me well enough to recognize that I wasn't an impostor.
