The Garden of Memories
Chapter 5: Inheritance
Shirou's finger froze on the yellowed page, breath catching as he spotted the Einzbern name amid the dense text. Unlike the historical texts they'd been examining, this hidden treatise contained actual technical details about the family's secretive homunculus development.
"Rin," he whispered, sliding the book toward her. "Look at this."
She leaned in, eyes tracing the paragraph describing specialized homunculi vessels designed to channel massive amounts of prana. Her expression sharpened with immediate recognition.
"These aren't just regular homunculi," Shirou murmured. "They're containers specifically designed for power."
"For the Grail," Rin clarified, her academic instincts taking over as she quickly connected the information to El-Melloi's earlier comments. "The Einzberns weren't just participating in the Wars—they were engineering the perfect vessel to contain whatever power emerged."
As she turned the page, Shirou noticed a marginal sketch—an ornate dress with spidery handwriting noting "Dress of Heaven - final vessel integration."
"What's that?" he asked.
Rin's fingers hovered over the illustration, a rare look of surprise crossing her face. "The Dress of Heaven," she whispered. "An Einzbern legend—supposedly the most powerful mystic code ever created for channeling Heaven's Feel." Her voice dropped further. "Most magi consider it mythical. I've never seen documentation confirming its existence."
"Could it be connected to what corrupted the Grail system?"
"It would explain—" she began, turning the page only to discover it had been torn out, leaving nothing but general homunculus theory in the remaining text.
Rin closed the book with a frustrated sigh, sliding it back into its place on the shelf. "Another dead end."
Shirou nodded, disappointment settling over him. "Should we take this to El-Melloi?"
"No point," Rin replied. "There's nothing here he wouldn't already know, and borrowing a book with pages torn out would only draw unwanted attention."
As she spoke, her posture subtly changed—shoulders tensing, fingers stilling on the book's spine. Without looking up, she murmured, "Don't turn around immediately, but we're being watched."
Shirou continued scanning the text before him, resisting the urge to look. "Who?"
"Third bookshelf to our left. Luvia Edelfelt and two of her research assistants." Rin's voice was barely audible. "They've been circling our section for the past fifteen minutes, pretending to browse Spiritual Evocation texts that shouldn't even be in this wing."
Now that Rin mentioned it, Shirou could feel the weight of observation—that subtle prickling at the back of his neck he'd developed during the Holy Grail War. With practiced casualness, he reached for another volume, using the movement to glance briefly in the direction Rin had indicated.
Sure enough, Luvia stood partly concealed behind a tall shelf, golden ringlets unmistakable even in the library's subdued lighting. She wasn't even pretending to read, instead watching them with unabashed interest while one of her companions took notes in a small leather-bound journal. When she caught Shirou looking, she offered a brilliant smile rather than turning away—confident enough in her position to acknowledge her surveillance openly.
Raising a finger to her lips, Rin glanced at both ends of the aisle. After confirming they were otherwise alone, she drew a small bounded field around them—nothing elaborate, just enough to ensure their conversation wouldn't carry. Shirou felt the air pressure shift around them like a thin curtain."
"What do you make of this?" Shirou asked quietly when she finished, tapping the book where they'd found the Einzbern reference.
"Some of the stiffness left her posture as she sighed and shook her head. "Let's stop here for now. This connection to the Einzberns is interesting, but without more evidence, we can't be sure we aren't just chasing ghosts.
"We need to be careful about what he's telling us," Shirou said, his tone thoughtful. "He's helping us, but he has his own reasons. Even if he's telling the truth about the Grail and the Servant, that doesn't mean he isn't being selective with information. Until we understand what he's really after, maybe we should be cautious about what we share too."
Rin's eyebrows rose slightly, genuine surprise flickering across her features before a small, approving smile took its place. "Exactly. When did you start thinking like a seasoned magus, Emiya?"
"I've been paying attention to how you handle things," he replied with a slight shrug. "This place demands more awareness than Fuyuki did. I'm just trying to keep up."
Across the library, Luvia's expression had shifted to one of evident frustration as she realized their voices no longer carried to where she stood. She whispered something to her companions before moving away, her departure as deliberately graceful as everything else she did.
"Don't forget what makes you different from the rest of us," Rin said, her expression softening momentarily as she watched Luvia disappear among the stacks. "Your straightforward approach has saved us before when my careful planning couldn't. We need both."
Shirou blinked, momentarily caught off guard by her candor. In all their time together, Rin had rarely acknowledged his approach as anything but reckless or naive. The admission seemed to hang in the air between them, unexpectedly significant.
"I... thank you," he managed, feeling an unusual warmth at her words. "That's not something I expected to hear you say out loud."
A faint flush colored Rin's cheeks as she hastily returned her attention to her book. "Don't let it go to your head. I'm simply acknowledging tactical realities."
Despite her dismissive tone, Shirou couldn't help but smile. Even Rin's compliments came wrapped in pragmatism, but that didn't diminish their meaning.
"Finding the middle ground," he said, returning to the text before him. "Just like you told me before the practical."
They worked in companionable silence for a while, the only sounds the occasional turning of pages and the distant murmurs of other students in far corners of the library. Shirou found himself falling into a rhythm, scanning historical records for any mention of the Third War while occasionally jotting notes in the margin of his notebook.
He paused when he encountered a brief reference to the Tohsaka family's role in establishing the original Grail system. The text mentioned three founding families but provided few details beyond their names: Tohsaka, Matou, Einzbern. Even after all they'd been through, the historical connections between these families remained largely mysterious to him.
"Rin," he said quietly, "this text mentions your family helped create the Grail system, but doesn't explain why the Matou were involved or what their specific contribution was."
Rin didn't immediately look up from her own research. When she did, her expression was uncharacteristically distant, as though his question had pulled her from some deeper contemplation.
"The Matou specialized in absorption magecraft," she replied, her voice carefully neutral. "They designed the Command Seal system and the spiritual vessels that would contain the Servants." Her fingers traced absently over the page before her. "That's the official history, anyway."
Something in her tone caught Shirou's attention. "And the unofficial history?"
Rin's fingers stilled on the page. She stared at the book for several long moments, seemingly weighing something in her mind. Finally, she closed it and looked up at him.
"I've been thinking about the questions El-Melloi is likely to ask," she said, her voice low despite the library's emptiness around them.
The sudden gravity in her manner made Shirou set aside his own research, giving her his full attention.
"What is it?"
Rin's gaze dropped briefly before meeting his again with renewed resolve. "It's about Sakura." Her voice faltered slightly, fingers unconsciously tightening around the book she held. "About why I kept my distance from her all these years." She took a measured breath, her composed expression slipping momentarily to reveal something raw beneath. "Sakura wasn't just my underclassman, Shirou. She was born Sakura Tohsaka. My younger sister."
The revelation landed with the weight of stone. Shirou felt his breath catch as pieces of a puzzle he hadn't even known existed suddenly rearranged themselves in his mind.
"Your sister?" he managed, trying to reconcile this with everything he'd observed over the years—two girls who'd barely acknowledged each other's existence despite attending the same school.
"Yes," Rin confirmed, her face pale but composed as she leaned against the table. "When she was five years old, my father gave her to the Matou family. The Matou line was failing—no suitable heirs with viable magic circuits. They needed new blood." She paused, her mask of composure melting away. "I just... stood there. I watched it happen."
In that moment, Shirou could almost imagine it. The image of Rin overlaid onto her six year old self.
"I was too young to understand what was happening," she continued, the mask slipping back on. "By the time I realized—after my father's death—it was already done. The adoption was ritually and legally binding. She was a Matou, and I was a Tohsaka."
"That's why you kept your distance," Shirou said, understanding dawning. "It wasn't your choice."
"Not initially," Rin admitted. "The terms of the transfer forbade contact between us. Later, when I became head of the Tohsaka... I told myself it was kinder to maintain that separation. That acknowledging our connection would only make things harder for both of us."
She looked away, and for just a moment, her usual perfect posture faltered. "Every time I saw her at school, I looked for glimpses of the little girl I remembered." The admission was quiet, almost involuntary.
A memory surfaced in Shirou's mind—a moment during the War when he'd caught Rin watching Sakura from a distance, her behavior uncharacteristically furtive.
"Now it makes sense," he said quietly, the missing piece to that puzzle falling into place, "Back then, during the War, I caught you following her home one time. You pretended it was nothing, but when I asked if something was wrong with Sakura..." He paused, recalling how abnormally defensive Rin had been. "You told me to drop it. That I'd only make things worse."
Rin winced visibly. "I remember. You thought I was jealous of her." A humorless laugh escaped her. "If you'd known the truth then—"
"I thought you were jealous of the time she spent at my house," Shirou admitted. "I had no idea..."
"That she was my sister?" Rin shook her head. "How could you have? We both played our parts perfectly." Her voice dropped. "You even asked me directly if something was wrong with her. I wanted to tell you then. But the words wouldn't come."
"Why tell me now?" Shirou asked quietly.
Rin took a deep breath. "The terms of the transfer forbade contact between us. But I couldn't just... ignore her existence completely. So I'd check on her from a distance. Tell myself I was just being prudent with the War happening." Her voice grew quieter. "I convinced myself it was enough. That acknowledging our connection would only make things harder for both of us."
The admission seemed to cost her something vital. Rin Tohsaka, who prided herself on perfect control, on always making the rational choice, revealing what might be her deepest regret.
"I'm telling you this now because El-Melloi might already know about our relationship," she continued, more composed. "The transfer of a Tohsaka child to the Matou family is documented somewhere in the Clock Tower archives."
"You don't want to be caught off-guard if he brings it up," Shirou concluded.
"Yes." Rin's eyes met his, something vulnerable flickering behind her composed exterior. "And because I'm tired of pretending she was nothing to me. Of acting like her death was just another unfortunate event in the War's aftermath."
The admission hung between them, Rin's usual armor momentarily lowered. Shirou felt honored by her trust, and burdened by it too—understanding better now the layers of grief she carried.
"Thank you," he said simply. "For trusting me with this."
Rin nodded once, the motion sharp as she visibly rebuilt her composure. "It doesn't change our approach with El-Melloi. The strategy remains the same."
"Except now I understand why this matters so much to you," Shirou said quietly. "Finding the truth about what happened to her. What the Matou did."
"It's not just about closure," Rin replied, standing and returning her book to the shelf. "If Sakura was connected to the Grail system through those worms, if Zouken was using her as some kind of vessel for corrupted power from a previous War..." Her hands stilled on the spine of the returned book. "Then understanding what happened might be the only way to ensure it never happens again."
Shirou rose as well, recognizing the determination behind her words. This wasn't just about grief or guilt or even justice—though all those elements were present. This was about Rin doing what she believed a Tohsaka should: protecting the integrity of the system her family had helped create, even when that meant confronting painful truths.
"We should prepare for the meeting," Rin said, her usual efficiency returning. "El-Melloi expects us at three."
The clock in the library chimed the half-hour, reminding them of time's steady passage. They gathered their materials quietly, each processing the weight of Rin's revelation in their own way. The truth hadn't changed the past, but it had shifted something in their understanding of it—casting new light on shadows they'd previously accepted without question.
As they made their way toward the exit, a familiar hooded figure appeared in the doorway—Gray, her face as always partially hidden beneath her cloak.
"Tohsaka. Emiya," she greeted softly. "Lord El-Melloi sent me to find you. He would like to begin earlier than scheduled, if you're available."
Rin and Shirou exchanged glances. "We were just heading back to prepare," Rin replied carefully.
"Is there a reason for the change?" Shirou asked.
Gray's eyes flickered briefly to his before dropping away. "He received some information this morning. From the Association's investigators in Fuyuki." She hesitated. "He seemed... concerned about its implications."
Shirou felt Rin tense beside him. New information from Fuyuki could change the delicate balance of their arrangement with El-Melloi.
"We'll come now," Rin decided, her voice betraying none of her apprehension. "Lead the way."
As Gray led them from the library toward El-Melloi's office, they passed a small alcove where several students huddled around a table, their voices carrying despite their attempts at discretion.
"...completely unorthodox approach. Tohsaka demolished Mercer with barely any gemcraft—just physical combat!" The speaker, a thin young man in a perfectly pressed uniform, gestured emphatically. "And the apprentice boy's projection..."
His companion leaned closer, the distinctive blue-and-gold Spiritual Evocation Department insignia pinned prominently to her lapel marking her as one of Luvia's cohorts. "Lady Edelfelt believes his abilities warrant special study. The Materials Transmutation Department is already petitioning for transfer rights."
A third student scoffed. "Good luck with that. El-Melloi's claimed them both—word is he's established exclusive mentorship under some obscure bylaw. The Modern Magecraft faculty voted unanimously to support it."
Gray smoothly altered their course, guiding Shirou and Rin down a less trafficked corridor.
"It's been like this since your demonstrations," she murmured, her voice barely audible. "Every department has an opinion about your placement. Several faculty members have already requested private audiences with Lord El-Melloi to discuss 'collaborative research opportunities'—their way of requesting access to you both."
She glanced back, eyes briefly visible beneath her hood. "I suggest using the eastern passageways for the next few days. They're less frequented by those seeking to advance departmental agendas through... strategic alliances."
Rin's expression hardened as they walked, the whispered conversations confirming what she'd already suspected—they had become valuable commodities in the Clock Tower's political marketplace. She exchanged a meaningful glance with Shirou, the unspoken message clear: they would need to be more careful than ever.
As they approached El-Melloi's office, the weight of what awaited them pushed these immediate concerns aside. Whatever the Clock Tower's politics, the truth about Sakura—and the corruption that had claimed her—took precedence over everything else.
The office was exactly as they'd left it the day before—cluttered with books and papers, the air thick with cigarette smoke despite the open window. The man himself stood by his desk, examining a letter bearing the Clock Tower's official seal. He looked up as they entered, dark circles beneath his eyes suggesting a night with little sleep.
Gray moved silently to the door, checking the corridor before shutting it firmly.
"Good, you're here," El-Melloi said without preamble. "Something's come up that changes our timeline."
Rin stepped forward, her expression cautious. "What's happened?"
El-Melloi gestured to a letter bearing the Clock Tower's seal. "The Association's team in Fuyuki has made an unexpected discovery."
Rin and Shirou exchanged glances. "What kind of discovery?" Shirou asked.
"A physical fragment of the Greater Grail itself," El-Melloi finished, "embedded in the foundation stones of the Matou estate."
Shirou's fingers dug into the armrests of his chair. The implications crashed over him - Sakura hadn't just been subjected to Zouken's familiars; she'd been connected to the Grail system itself. He glanced at Rin, whose face had gone completely pale, her composure momentarily fractured.
"That's impossible," she finally managed, her voice barely steady. "The Greater Grail is beneath Mount Enzou—has been for generations."
Gray silently placed a cup of tea before each of them. The brief interruption allowed Shirou to collect himself before El-Melloi continued with his next revelation.
"And yet," El-Melloi replied, tapping the Association letter, "their analysis is conclusive. What's more troubling is that this fragment wasn't simply hidden there—it was deliberately integrated into the estate's thaumaturgical framework."
He leaned forward, eyes sharp. "It bears traces of what appear to be Matou familiars—specifically, crest worms."
Rin stiffened visibly, her composure momentarily slipping. Shirou noticed her hand instinctively move toward her pocket before she caught herself.
"Crest worms?" Rin repeated, her voice carefully controlled. "You're certain of that identification?"
El-Melloi's eyes narrowed at her reaction. "Quite certain. The Association's team found several specimens in the ruins—mostly destroyed, but with enough intact structure for analysis." He studied her intently. "Your reaction suggests this information is significant to you, Tohsaka."
Shirou stepped in, drawing El-Melloi's scrutiny away from Rin. "We only learned about these familiars after... after what happened to Sakura," Shirou said carefully. "But they seemed central to the Matou magecraft."
"More than that," El-Melloi said, his tone shifting from informative to probing. "These familiars contained something the Association finds deeply concerning. Something that relates directly to our agreement."
He folded his hands on the desk, his posture subtly changing to one Shirou recognized from their first meeting—the calculating academic making a clear proposition. "I've shared information that hasn't yet reached the broader Association. In turn, I believe you both have evidence or observations that would shed light on what truly happened at the Matou estate." His eyes moved between them. "Perhaps now would be the time to establish a more... equitable exchange."
The carefully worded suggestion hung in the air. This wasn't the casual sharing of research findings but a deliberate invitation to formalize their arrangement.
Rin's fingers drifted to her pocket, where Shirou knew she kept both Sakura's charm and something else—something she'd never shown him. He watched as her expression tightened with internal conflict, hesitation flickering briefly in her eyes before hardening into reluctant resolve.
"I..." she began, then stopped, uncharacteristic uncertainty in her voice. Her hand trembled slightly against her pocket before she withdrew it, clenching it into a fist at her side instead.
"Tohsaka," El-Melloi prompted, his tone softening slightly as he observed her struggle. "Whatever you know could be crucial, and in exchange, I can offer context that the Association would prefer remained buried."
Rin took a deep breath, her gaze meeting Shirou's for a moment—seeking something, perhaps permission or reassurance. Then, with visible reluctance, she reached back into her pocket.
"I have something," she said finally, her voice barely above a whisper. "Something I've kept... from Sakura."
Each word seemed to cost her, as if the act of revealing this secret was physically painful. With careful, almost reverent movements, she withdrew not the velvet pouch containing Sakura's charm, but a small vial sealed with preservation runes.
Shirou stared, understanding dawning with sickening clarity. This was what had been inside Sakura—what had been consuming her from within. The implications hit him with visceral force—Rin had been carrying this reminder of horror with her all this time, through the funeral, the flight to London, their first days at the Clock Tower. While he had carried dust from a cherished gift, she had shouldered the burden of carrying the very thing that had destroyed her sister.
El-Melloi's eyes widened slightly, the only betrayal of his surprise. "You preserved one," he said, his tone shifting from demanding to respectful. "That was... foresighted."
"It wasn't foresight," Rin replied, her voice breaking despite her obvious effort to maintain control. For a moment, her carefully maintained composure fractured completely, raw grief and guilt flashing across her features before she mastered herself again with visible effort. "It was evidence."
Her voice steadied, but her fingers trembled visibly as she placed the vial on El-Melloi's desk, her movements so careful they seemed almost ritualistic. "I needed to understand what had been done to her. I needed to know what I—" She cut herself off, swallowing hard, the unfinished thought hanging between them like a confession.
Taking a steadying breath, she continued more clinically, though the strain in her voice belied her professional tone, "The preservation spells should have maintained its thaumaturgical signature."
Gray had moved closer, her hooded face turned toward Rin with what appeared to be compassion, though she remained silent. Even El-Melloi seemed affected by the moment, his usual analytical detachment giving way to something more human as he regarded the vial with a mixture of scholarly interest and instinctive revulsion.
"This will help considerably," he said finally, his voice gentler than Shirou had yet heard from him. "The spiritual signature is remarkably preserved." He looked up at Rin, something like respect in his gaze. "May I ask how long you've been carrying this with you?"
"Since we found her," Rin answered simply, the three words containing volumes of unspoken grief.
Shirou watched her, seeing for the first time the depth of the burden she'd been carrying—not just grief and guilt, but a physical reminder of her failure that she kept close, perhaps as penance, perhaps as purpose.
After El-Melloi secured Rin's preserved specimen in a warded container, a moment of contemplative silence fell over the office. Shirou's hand unconsciously drifted to his own pocket, where the velvet pouch containing Sakura's shattered whetstone dust rested. He'd kept it with him constantly since her death, this last physical connection to her.
He found himself studying the locked drawer where El-Melloi had placed the container with the crest worm. Rin had carried that grotesque reminder on her person for days—a burden she bore in private until now, when sharing it might lead to answers about Sakura's fate.
The weight of his own secret suddenly felt heavier. Unlike the worm, which Rin had carried as a silent burden all this time, the whetstone had been given with simple affection, with the request that he think of her when he cooked. It wasn't evidence; it was memory.
Yet it had shattered at the moment of Sakura's death. The timing couldn't be coincidence—it had to be connected to whatever spell she'd cast, another piece of the puzzle they were trying to assemble.
"There's something else," Shirou said before he could reconsider, drawing surprised looks from both Rin and El-Melloi. "Something I've been carrying."
Carefully, he withdrew the velvet pouch and placed it on the desk. "It's a whetstone Sakura gave me, just days before..." He swallowed hard. "It shattered at the exact moment she died. Turned to dust."
El-Melloi's eyes widened slightly, his attention immediately focused on the pouch. "May I?" he asked, with unexpected restraint.
At Shirou's nod, El-Melloi examined the pouch without opening it, his expression shifting to one of professional interest.
"Another conduit," he murmured. His eyes narrowed slightly as he studied the pouch. "The Association's team found something similar in your kitchen in Fuyuki, Emiya."
Shirou stiffened. "My kitchen? What did they find?"
"A ceramic bowl with broken pieces arranged in a specific pattern," El-Melloi explained, watching Shirou's reaction carefully. "The fragments bore unusual thaumaturgical residue. Our analysis suggested it served as some kind of anchor point for a spell."
"The bowl Sakura dropped," Shirou whispered, the memory suddenly vivid. "The last time she visited... she broke a bowl. I left the pieces there, intending to clean them up later."
El-Melloi nodded, pieces falling into place. "She created multiple paths for her magecraft, ensuring the connection would hold even if one failed." There was a note of respect in his voice. "More sophisticated spellwork than anyone would have expected from someone with such limited formal training."
He carefully secured both specimens in separate warded containers, his movements precise and deliberate, almost reverent. When he finished, he straightened, surveying them both with a changed expression—no longer the demanding investigator but a collaborator with shared purpose.
"You've both shown considerable trust," he said, his tone warmer than before. "And that deserves reciprocation."
El-Melloi moved to a cabinet behind his desk and unlocked it, removing what appeared to be a grainy photograph in a protective sleeve. He placed it on the desk, turning it toward them. The image was clearly taken from a distance with a telephoto lens—a surveillance photo showing a man in a dark coat walking through Fuyuki's downtown district, his profile partially visible.
"Kiritsugu Emiya," El-Melloi said, his voice taking on a subtly different tone. "Taken by Association observers monitoring the Fourth War. One of the few images we have of the Magus Killer during active operations."
Shirou leaned forward, his breath catching as he recognized the profile despite its poor quality. Even in this grainy, distant image, there was something unmistakable about his father's posture—rigid and alert, so different from the tired, gentle man Shirou had known.
"My father," he whispered, the words escaping involuntarily. "He was there."
"Yes," El-Melloi confirmed, something unreadable flashing across his features. "Hired by the Einzbern family as their representative in the Fourth War. A mercenary specializing in hunting rogue magi," El-Melloi elaborated, his tone clinically detached. "Known for using unconventional methods—firearms, explosives, poisons—rather than traditional magecraft. The Einzberns hired him precisely because of his reputation for ruthless efficiency which earned him the moniker, the Magus Killer."
Shirou stared at the photograph, unable to reconcile this severe stranger with the broken man who had raised him. "The Magus Killer," he repeated, the title still foreign on his tongue despite having heard it before.
His hand trembled slightly as he reached toward the photograph, not quite touching it. A rushing sound filled his ears as fragmented memories collided with this new reality - Kiritsugu teaching him to cook with patient hands, Kiritsugu staring into the distance with hollow eyes, Kiritsugu coughing blood into a handkerchief he thought Shirou hadn't seen. The same man who had pulled him from the flames had been there when those flames began. His savior and potentially the architect of the very disaster that had orphaned him.
"My father was there," he whispered, the words escaping involuntarily. "He was part of it all." His throat constricted as he struggled to align these two irreconcilable versions of the man who had raised him - the gentle, broken father and this severe operative captured in grainy surveillance.
Gray shifted slightly by the door, her hooded gaze briefly meeting El-Melloi's before dropping away.
"He never told me," Shirou said, still staring at the photograph. "About any of this."
El-Melloi watched him carefully. "Would you have understood? A child, bearing the weight of such knowledge?"
Before Shirou could respond, Rin interjected, drawing the conversation back to the immediate concern. "What does this have to do with the Matou familiars? With what happened to Sakura?"
El-Melloi's expression hardened as he returned the photograph to its place. "The connection becomes clear when we understand what happened during the Fourth War." He paused, hands resting on the edge of his desk. "Something went wrong with the Grail system. Catastrophically wrong."
The air in the office seemed to grow heavier, charged with the weight of revelations to come. El-Melloi moved to a bookshelf, his fingers tracing the spines until he found what he sought—a slim volume bound in dark leather with no visible title. The book hummed faintly with contained magecraft as he set it on the desk.
"To understand that, we need to go back further," he said, breaking the warded seal that kept the book closed. "To the Third War, when the corruption first took root."
The pages fell open to reveal handwritten notes and diagrams, the script precise but hurried, as if documenting revelations that might otherwise slip away. Illustrations of the Greater Grail's structure were annotated with observations about its corruption.
"The Einzberns didn't merely participate in the Third War—they deliberately subverted it," El-Melloi continued, voice low. "After failing in the previous Wars, they manipulated the system to summon something outside the standard seven classes."
Shirou felt a chill run down his spine as the book creaked ominously. El-Melloi turned the page, revealing a sketch that seemed to absorb the surrounding light—a humanoid figure wrapped in shadows, its form indistinct except for a halo-like crown above its head. Gray, standing silently by the door, visibly stiffened.
"Avenger," El-Melloi said simply, the word hanging in the air like a curse.
A flash of memory struck Shirou—a sensation of overwhelming darkness from his dreams, a well of corruption that had no bottom. His breath hitched, drawing concerned glances from both Rin and Gray.
"Shirou?" Rin's voice cut through the sudden fog in his mind.
"I've... seen it," Shirou managed, his voice strained. "In dreams. After the War."
El-Melloi's expression sharpened with interest. "Not surprising. You were exposed to the Grail's manifestation in both Wars." He studied Shirou with renewed attention. "Your father was the only Master in the Fourth War who truly understood what the Grail had become."
The connection between Kiritsugu and the corrupted Grail hung unspoken between them. Shirou's hands gripped the arms of his chair, steadying himself against the implications unfolding before him.
"An eighth class?" Rin interjected, her face pale. "That's theoretically impossible. The system only recognizes seven containers—"
"Under normal circumstances, yes," El-Melloi cut her off, his composure slipping further. "But the Einzberns found a way to bypass the safeguards—circumventions that your family never anticipated, Tohsaka."
Rin's jaw tightened perceptibly at this, dismay and something like guilt flickering across her features. Another Tohsaka family failure exposed—another piece of her heritage that had contributed, however unwittingly, to tragedy.
El-Melloi continued, his voice growing colder. "This Avenger represented all the world's evils. It was defeated early in the War, but instead of returning to the Throne of Heroes, it was absorbed into the Greater Grail itself."
"Where it waited," Shirou said quietly, understanding dawning, "corrupting the system from within."
Gray approached the desk, her hood falling back slightly as she examined the book. "Lord El-Melloi, perhaps..." she began, her quiet voice carrying an unusual note of concern.
El-Melloi raised a hand, acknowledging her unspoken warning. "Yes. We should proceed carefully." He closed the book, some of the tension in the room dissipating with it. "The corruption remained dormant until the Fourth War, when the Grail began to manifest physically."
Shirou stared at his hands, processing what he'd heard. "And my father... he was there."
"Not just there," El-Melloi clarified, something complex shifting in his expression. "Kiritsugu Emiya was the only Master who recognized the truth—that the Grail had become a vessel for corruption rather than wishes. He made the decision to destroy it."
The implication struck Shirou with physical force. "The fire," he whispered, fragments of his earliest memories surfacing—heat, smoke, the sensation of life slipping away. "The Fuyuki fire that killed my family... that nearly killed me..."
"Was the result of the corrupted Grail's contents spilling into our world," El-Melloi confirmed quietly. "Your father ordered his Servant to destroy the physical manifestation, preventing something far worse."
The office fell silent as the weight of this revelation settled over them. Gray moved to a side table, preparing cups of tea with movements both practical and elegant—a simple gesture of normalcy amid revelations that threatened to overwhelm.
El-Melloi accepted a cup from her with a slight nod of thanks, his hand trembling almost imperceptibly. The momentary vulnerability was quickly masked as he turned back to Shirou and Rin.
"Your father changed after that," he said, addressing Shirou directly. "The reports indicate he abandoned magecraft almost entirely. Disappeared from the Association's radar except for occasional sightings."
Shirou stared into the tea Gray had placed before him, seeing only amber depths that offered no answers. "He never used magecraft at home," he said quietly. "Taught me only the basics. Always seemed... reluctant."
"A man haunted by consequence," El-Melloi observed, something like understanding in his voice. "But that reluctance didn't prevent him from passing key elements of his craft to you."
Shirou looked up sharply. "What do you mean?"
El-Melloi's eyes held his, searching. "Your reinforcement techniques. Your analytical approach. These are adaptations of methods Kiritsugu Emiya was known for, albeit applied to different ends."
This observation settled into Shirou like a weight and a comfort simultaneously—another connection to the man who had raised him, yet another reminder of how little he had truly known his father.
Rin, who had been absorbing this information in tense silence, leaned forward. "This still doesn't explain the connection to the Matou familiars. To what happened to Sakura."
El-Melloi nodded, setting down his tea. "After the Fourth War, fragments of the corrupted Grail remained scattered throughout Fuyuki. Most were inert, their power dispersed. But the Matou..." His expression darkened. "Their specialization in absorption magecraft made them uniquely equipped to harness what remained."
He reached for the leather-bound book again, turning to a different page. This one showed a diagram of magic circuits intertwined with worm-like creatures.
"The corruption that remained in the Grail system somehow found its way into Zouken Matou's familiars," El-Melloi explained, his academic tone returning as if to distance himself from the horror of what he described. "The same familiars he used to corrupt Sakura."
The room seemed to grow colder as El-Melloi continued. "He introduced these corrupted familiars into Sakura's body, creating a direct connection between her and the Grail's corruption. What he couldn't have anticipated was how that connection would evolve over time—how the corruption would eventually consume not just Sakura, but himself and his entire legacy."
Shirou's hands clenched into fists, a familiar anger burning through him. The image of Sakura suffering such violations made him physically ill. Gray approached, refilling his tea with quiet thoughtfulness, her presence somehow steadying despite her silence.
"She knew," he said suddenly, looking up at El-Melloi. "Toward the end, Sakura knew what was happening to her. That's why she gave us those objects—the whetstone, the charm. She was preparing."
Rin's breath caught audibly, her composure momentarily fracturing. Her fingers reflexively reached for her pocket where Sakura's charm rested.
"She was fighting back," Rin whispered, fierce pride breaking through her grief.
Shirou's body reacted before his mind could fully process what he'd heard. Color drained from his face, leaving him ghostly pale, while a cold sweat beaded across his forehead. His breathing became shallow and rapid, fingers digging into the armrests until the wood creaked in protest. The horrifying connection between his father's actions during the Fourth War, the corrupted Grail, and Sakura's suffering hit him like a blow to the chest, leaving him visibly shaking. For a moment, he seemed to fold in on himself, shoulders hunching as if under an overwhelming weight, his eyes unfocused and distant as the terrible implications cascaded through his consciousness.
"Perhaps we should continue this another time," Gray suggested, her gentle voice cutting through the tension.
El-Melloi looked up sharply, as if suddenly remembering Gray's presence. He studied Shirou's pale face and rigid posture for a moment, then gave a measured nod, some of the intensity leaving his expression.
"Yes," he agreed, straightening the papers on his desk with unusual care. "This is... sufficient for today." His voice shifted back to its customary professional tone. "Gray, would you show Emiya to the eastern courtyard? He looks like he could use some air."
As Shirou rose to follow Gray, El-Melloi added, "Tohsaka, if you could remain a moment. There's something specific about the Grail's structure I'd like to discuss with you."
The careful phrasing made it clear this was information he preferred to share with Rin alone. She glanced at Shirou, silently questioning if he would be alright.
Shirou nodded, grateful for the chance to process everything he'd learned about Sakura's connection to the Grail. The door closed behind him and Gray with a definitive click.
The eastern courtyard, when they reached it, was indeed deserted. Unlike the manicured central grounds where students gathered between classes, this smaller space had a neglected quality—ivy climbing unchecked up stone walls, weathered benches positioned beneath an ancient oak tree whose branches reached toward a narrow patch of sky visible above the surrounding buildings.
"The faculty rarely comes here," Gray explained, her voice soft as always. "And most students prefer the main courtyard with its proximity to the dining hall."
Shirou nodded gratefully, taking a seat on one of the benches. The solitude was exactly what he needed—space to process the revelation about his father's involvement in the Fourth War, about the origin of the fire that had claimed his first family and set him on this path.
Gray remained standing, seemingly unsure whether to leave him to his thoughts or stay. After a moment's hesitation, she chose a middle path, moving to a respectful distance where she examined a climbing rose that had managed to establish itself along one wall.
"You knew, didn't you?" Shirou finally asked, breaking the silence. "About my father. About his connection to the Fourth War."
Gray turned, her hood falling back slightly to reveal more of her face than usual. Without directly meeting his eyes, she chose her words carefully. "Lord El-Melloi has... extensive knowledge of the Fourth War. He has studied its participants and outcomes more thoroughly than perhaps anyone at the Clock Tower."
"That's why he sought us out specifically," Shirou concluded. "Not just because of the Fifth War, but because of my connection to Kiritsugu."
"His reasons are his own," Gray replied, neither confirming nor denying Shirou's suspicion.
Shirou studied her carefully, noticing the deliberate distance she maintained even while offering help. Something about her restraint reminded him of Saber—that same quiet dignity in the face of circumstances beyond her control.
"You understand it, don't you?" he asked quietly. "Living in someone else's shadow."
Gray's eyes widened slightly, clearly caught off guard by his perception. For a moment, she seemed to wrestle with some internal decision. Then, with deliberate purpose, she crossed the small distance between them and sat on the bench opposite him, lowering her hood completely for the first time since they'd met.
Her green eyes—so hauntingly familiar—met his with unexpected directness. The resemblance to Saber was painful in its perfection, yet there was something uniquely Gray in her gaze—a different kind of strength, a different kind of burden. Where Saber's eyes had always carried the weight of a kingdom and the isolation of a king, Gray's held something entirely different—a quiet resilience born of personal struggle rather than royal duty.
"Legacies shape us, but our choices define us," she said, her quiet voice carrying unexpected weight in the stillness of the courtyard.
The words struck Shirou with physical force, stopping his breath. In that simple sentence, Gray had articulated the exact struggle that had been consuming him since learning of Kiritsugu's role as the Magus Killer. His hand trembled slightly as he processed the implications.
"That's..." he began, then stopped, searching for words. "How can you be so certain? When the legacy is so heavy it feels like it's already made all your choices for you?"
His voice had taken on an unexpected rawness, the carefully maintained composure cracking as he gave voice to the fear that had been building since El-Melloi's revelations. Was he simply walking the path Kiritsugu had laid out, unconsciously following his father's footsteps? Was his projection magecraft merely an echo of the Magus Killer's analytical approach to combat?
Gray studied him, her green eyes reflecting the fading light. There was no judgment in her gaze, only a deep understanding that seemed to transcend her apparent age.
"Because I live it every day," she replied, her voice stronger now. "This face I wear—it wasn't my choice. But what I do with it, how I carry myself despite it..." Her hand rose briefly toward her hood before dropping back to her lap. "Those choices belong to me alone."
Shirou found himself studying her face, not searching for echoes of Saber as he might have days ago, but seeing Gray herself—the person who existed beyond the familiar features. In her words, he heard not just wisdom but hard-won experience, a battle for identity he recognized all too well.
"I've been unfair to you," he admitted suddenly. "Seeing the resemblance without acknowledging the person."
Gray's eyes widened slightly in surprise.
"You're nothing like her," Shirou continued, the realization solidifying as he spoke. "You share a face, but everything else—how you move, how you speak, how you see the world—it's entirely your own."
A flicker of something like gratitude passed across Gray's features. "Most people here see only what they expect to see," she said softly. "Either someone to be studied because of my unusual circumstances, or a useful tool because of my connection to ancient magecraft."
"Is that how El-Melloi treats you?" Shirou asked, genuine concern in his voice.
Gray shook her head. "No. He's different. He sees me as a person first, despite knowing more about my... situation than anyone." She looked up at the oak leaves rustling above them. "That's rare among magi. Most are too fixated on bloodlines and mysteries to see the human carrying them."
Shirou understood that sentiment all too well. In the world of magi, a person's worth was often measured by their thaumaturgical potential or usefulness rather than their character. He'd experienced it firsthand since arriving at the Clock Tower—professors evaluating his circuits rather than his dedication, students interested in his projection techniques rather than his motivations.
Even Rin had initially approached him that way during the Holy Grail War, assessing his thaumaturgical potential with clinical precision. But unlike most magi, she'd evolved beyond that initial evaluation. She'd come to see him as a partner, as someone whose worth transcended his abilities. Their journey had transformed them both—teaching Rin to value connection alongside capability, while showing Shirou the importance of strategy alongside idealism.
It was this growth that made their current partnership work, this mutual recognition of each other as people first, magi second. The thought made Shirou wonder if Gray had found something similar with El-Melloi—a relationship that valued her personhood above her mysteries.
Gray nodded, her expression softening slightly. For a moment, they sat in companionable silence, two people who understood something essential about each other despite their brief acquaintance. The realization that Gray had found someone who saw beyond her circumstances made Shirou curious about her relationship with the department head.
"Is that why you stay with him?" Shirou asked. "With El-Melloi?"
Gray's lips curved in a ghost of a smile—the first genuine expression he'd seen from her. "I stay because he sees beyond what I resemble to who I am," she said, a warmth entering her voice that transformed it entirely. "In a place obsessed with lineage and inheritance, he understands that we are more than what we've been given or had taken from us."
She looked up at the oak tree spreading its branches above them. "He offered me the rarest gift at the Clock Tower—the freedom to define myself."
The earnestness in her voice struck Shirou deeply. Here was someone who truly understood what it meant to live beneath the shadow of another's legacy. Not just understood it, but had found a way forward.
"My father," Shirou said, the words emerging before he'd fully formed the thought, "I always thought of him as broken. As someone who had failed to become what he wanted to be." His eyes followed a falling leaf as it spiraled down from the oak. "But what if destroying the Grail wasn't his failure, but his triumph?"
Gray watched him with quiet attentiveness, allowing him space to work through his realization.
"When he destroyed the Grail," Shirou continued, "he made the hardest possible choice. He sacrificed his own ambitions to prevent something worse." A clarity was forming within him. "Just as we did in the Fifth War. We refused to let that corruption continue, even when walking away would have been easier."
Gray nodded solemnly. "Most magi would sacrifice anything—even others—to achieve their goals." A shadow passed across her face. "Zouken Matou being perhaps the most extreme example."
The mention of Zouken brought Shirou's thoughts immediately back to Sakura—to her suffering, to the mystery of what had been done to her. To the empty space in his pocket where the whetstone dust had been.
"Gray," he asked, his tone shifting to something more urgent, "this Avenger that El-Melloi mentioned—the corruption it brought to the Grail system... Do you think that's what affected Sakura through those worms?"
Gray straightened slightly, caution returning to her manner. "I shouldn't speculate on matters Lord El-Melloi is still investigating," she said carefully. "But connections rarely form by accident in thaumaturgy. The Matou specialization in absorption magecraft would have made them particularly... susceptible to certain influences."
She rose from the bench, brushing invisible dust from her cloak. "Lord El-Melloi believes the Matou were experimenting with something they didn't fully understand." Her voice dropped even lower. "Something that ultimately consumed them as surely as they sought to consume it."
The sound of approaching footsteps echoed down the corridor. Gray withdrew, her hood falling forward to once more shadow her features as Rin appeared in the courtyard's entrance.
Rin paused at the threshold, her sharp eyes taking in the scene. "There you are," she said, assessing Shirou before turning to Gray with a neutral nod. "Thank you for staying with him."
Gray inclined her head slightly. "It was no trouble." She moved toward the exit, pausing briefly beside Shirou. "Remember," she said, voice pitched for his ears alone, "your father's choices belong to him. Yours belong to you. Even when they echo each other."
With that, she slipped past Rin and disappeared into the corridor, her gray cloak merging with the stones until she was gone.
Rin watched her leave with a thoughtful expression before joining Shirou on the bench. The space Gray had occupied still seemed to hold the echo of her presence—that strange mixture of familiarity and difference that made each encounter with her both painful and clarifying.
"That was... surprisingly considerate of her," Rin said, studying Shirou's face with the attentiveness that had become more pronounced since Sakura's death.
"She understands more than most about inherited legacies," Shirou replied, feeling a new resolve taking shape within him. He turned to Rin, meeting her questioning gaze directly. "What did El-Melloi want to discuss with you? Was it about the Grail system?"
Rin's expression shifted, surprise momentarily visible before her usual composure returned. She studied him for a moment, perhaps noting the change in his demeanor following his conversation with Gray.
"Yes," she confirmed, a slight furrow appearing between her brows. "He had information about the Tohsaka family's role in designing the Grail system. Specific details about the containment structures that were meant to prevent corruption." Her fingers curled around the edge of the bench. "Structures that failed when the Avenger was absorbed."
The implication hung between them—that her family's design, however well-intentioned, had contributed to the catastrophe that ultimately claimed her sister. Another layer of complexity in the web of responsibility and consequence they were still unraveling.
"He also confirmed something I've suspected," Rin continued, her voice dropping lower. "The remaining investigators from the Association will be arriving in London next week to deliver their full report. They'll want to interview us both."
Shirou tensed. "About what happened to Sakura?"
"About everything. The Fifth War. The Matou estate. Our sudden departure from Fuyuki." Rin's eyes narrowed slightly. "El-Melloi believes he can shield us from the worst of their scrutiny, but only if we continue to cooperate with him."
"So we're still playing his game," Shirou observed.
"For now," Rin agreed. "Though I'm less certain of the rules than I was before."
The courtyard had grown darker as they spoke, the last of the afternoon light fading from the sky above them. A chill breeze rustled through the oak's branches, sending a scatter of leaves across the stones. One landed on the bench between them—amber and crimson, veins like magic circuits running through its fragile structure.
Rin rose from the bench with fluid grace. "I have some preparations to make for tomorrow's classes." She studied him carefully. "Will you be heading back to the flat?"
Shirou shook his head. "Not yet. I need to work through some things first. Maybe take a walk."
Rin's gaze lingered on him for a moment, assessing. "London isn't Fuyuki," she cautioned. "The streets can be... unpredictable after dark."
"I'll stay within the Clock Tower grounds," Shirou assured her. "I just need some air. Some movement to clear my head."
Something like understanding flickered in Rin's eyes. She knew his process by now—how physical action often helped clarify his thoughts when words and study failed. "Don't stay out too late," she said, her tone softening slightly. "We have an early start tomorrow."
"I won't," Shirou promised, meandering away as he started to organize the jumble of revelations swirling in his consciousness.
The Department of Modern Magecraft Theory maintained several practice rooms for students to refine their techniques outside of scheduled training sessions. Unlike the formal arena where their demonstrations had taken place, these smaller spaces offered privacy for those seeking to work through difficult spells—or difficult thoughts.
Long after most students had retired for the evening, Shirou found himself in the smallest of these rooms, a windowless chamber with reinforced walls and a bounded field that contained errant thaumaturgicall energy. The simplified training weapons lining one wall offered little appeal; instead, he stood in the center of the room, eyes closed, focusing on the steady rhythm of his breathing.
"Trace on."
The familiar incantation came automatically, a ritual that had become as natural as drawing breath. Magic circuits awakened beneath his skin, glowing faintly in the dim light. Tonight, however, he wasn't projecting weapons or reinforcing objects. Instead, he sought understanding through the most fundamental application of his abilities: structural analysis.
In his mind's eye, Shirou formed the image of the cherry blossom whetstone Sakura had given him—not as the pile of dust it had become, but as it had been when whole. Its dimensions, its weight, the subtle imperfections in its surface. He reconstructed it mentally, examining the grain, the pattern of the etching.
Had there been something hidden within its structure? Some clue he'd missed because he hadn't looked deeply enough?
The projection formed in his hand—an imperfect copy, yet noticeably more substantial than his failed attempt with the actual dust days ago. Where before there had been only frustration and disconnection, now a ghostly approximation of the whetstone materialized, its cherry blossom etching faintly visible. Shirou stared at it in surprise, recognizing this small victory where once there had been only failure.
"I couldn't restore it before," he murmured, turning the projected whetstone in his hand. "Not when it first crumbled."
This development represented more than just improved technique—it suggested a deeper understanding of the object's nature, of the connection it had embodied. Still incomplete, lacking the essence that had made Sakura's gift unique, but a significant step forward nonetheless. With renewed determination, Shirou pushed deeper, past physical properties into conceptual space, seeking the blueprint of the original with growing confidence in his evolving abilities.
Images flashed through his mind: Sakura's hands holding the stone, her fingers tracing the cherry blossom design. Her voice: "So you'll think of me when you cook." The whetstone being wrapped, carried, presented. The stone had history, connection—but he found no evidence of deliberate spellcraft embedded within it.
Frustrated, Shirou let the projection dissolve. If it hadn't been designed as a conduit like the broken bowl, why had it shattered at the moment of Sakura's death?
He reached for a different approach. Kiritsugu had taught him little about formal magecraft, but one lesson had always stayed with him: "Understanding comes from observation, not just action."
Observation. For years, Shirou had assumed his father was simply referring to structural analysis—his ability to observe the physical properties of objects. It had been the foundation of his magecraft, the first skill he'd truly mastered. See the object. Understand its composition. Recognize its weaknesses and strengths.
But now the word carried new weight. His failure with Sakura had taught him that observation went beyond mere physical assessment. It meant seeing beneath surfaces, recognizing patterns, understanding connections that weren't immediately visible.
"I observed the whetstone's structure," Shirou murmured to himself, "but not what it truly was."
With this expanded understanding, Shirou closed his eyes again, focusing not just on analyzing structure but on examining meaning. The events of the past weeks arranged themselves in his mind like pieces on a board: Sakura's deteriorating condition, the small signs he'd missed, the final meal they'd shared. The whetstone's gift, the broken bowl, the tea spilled across his floor.
What had once seemed like disconnected incidents now revealed themselves as part of a pattern—visible only when he truly observed rather than merely looked.
The whetstone. The broken bowl. The charm given to Rin. Each object carried something of Sakura with it—not just through thaumaturgical manipulation but through genuine emotional investment. Their purpose hadn't been primarily thaumaturgical; it was the connection itself that mattered. The thaumaturgy had merely been a consequence of that bond, not its purpose.
Understanding dawned on him with sudden clarity, like sunlight breaking through clouds.
"She wasn't creating conduits," Shirou murmured to the empty room. "She was saying goodbye."
Shirou's hands trembled slightly as he processed this understanding. Sakura had known she was dying. Had known that the worms were consuming her beyond recovery. Yet she had spent her final days not in bitterness or despair, but in creating these small, meaningful connections—ensuring that pieces of herself would remain with those she cared for.
"Trace on."
This time, the incantation came with renewed purpose. In his palm formed a delicate teacup—Sakura's favorite, the lavender one she always reached for when visiting his home. The blueprint in his mind was perfect, down to the tiny chip on the rim from when she'd accidentally knocked it against the table one afternoon. The cup hadn't just been a vessel for tea; it had been a vessel for countless quiet conversations, for shared moments of peace amid the chaos of their lives.
Beside it appeared a hair ribbon—violet, like her hair, the one she'd worn to archery practice. Shirou had never seen it up close, had never touched it, but he'd observed it countless times, noted how she'd adjust it before drawing her bow, how it had come to symbolize her dedication to the sport she loved.
Next came Kiritsugu's old lighter—tarnished silver, its engraving worn nearly smooth from years of handling. The object that had survived his father's countless journeys, that had been a constant presence in his final years. Shirou remembered how Kiritsugu's fingers would sometimes trace the faded pattern absently, as if reading a message only he could decipher.
The worn wooden spoon followed—the one Kiritsugu had used to teach him how to make traditional Japanese curry, guiding his small hands as they stirred together. "Not too fast," he'd said, his rare smile visible in the kitchen's warm light. "Let the flavors have time to find each other."
A blanket materialized next, suspended in the air—the one Sakura had brought over during a particularly cold winter, insisting that his house needed "warmer touches." She'd left it folded neatly on his couch, a splash of color in his otherwise utilitarian living space. He'd pretended not to notice how deliberately she'd placed it, how the small act of caring had revealed so much about her quiet devotion.
Last came the small notepad where Kiritsugu had written his grocery lists, his handwriting growing increasingly unsteady in his final months. Shirou had kept it long after his father's death, the mundane items—rice, miso, green onions—becoming a strange comfort, evidence of the ordinary life they'd carved out amid extraordinary circumstances.
As the projections multiplied, floating in the air around him, Shirou began to understand something that had eluded him before. His unusual aptitude for projection hadn't simply appeared by chance. It had grown from his desperate need to preserve what was lost, to hold onto connections that would otherwise fade with time.
"My magic is remembrance," he whispered, the realization clarifying something fundamental about himself.
The projections around him stabilized, becoming more solid, more real. Not perfect reproductions but meaningful interpretations—objects that captured not just physical properties but emotional resonance. This was the core of his ability, the thing that made his projection different from standard magecraft.
And it had been there all along, planted perhaps by Kiritsugu—not through formal training, but through example. The Magus Killer, a man who had sacrificed everything to prevent a greater catastrophe, who had then devoted his remaining years to raising an orphaned boy with kindness and imperfect wisdom.
The door to the practice room opened quietly. Shirou turned to find Rin standing in the threshold, her expression shifting from concern to surprise as she took in the array of projected objects hovering in the air around him.
"Couldn't sleep?" she asked, stepping inside and closing the door behind her.
Shirou let most of the projections fade, keeping only the teacup and the blanket—the two that most strongly connected to Sakura. "I needed to work through some things."
Rin nodded, understanding without requiring explanation. "I checked three rooms before finding you. I thought you might be practicing combat techniques."
"This is more important," Shirou replied, gently holding out the projected teacup for her inspection. "I've been thinking about connections—about how objects carry history, not just physical properties, but emotional resonance."
Rin approached slowly, her eyes moving from one projection to the other. She reached out tentatively toward the blanket but stopped just short of touching it, as if afraid her fingers might pass through the memory. "Sakura's," she said softly, not a question but a recognition. "She bought it during winter break last year. Said the color reminded her of sunset."
The fact that Rin knew this detail—something Shirou himself hadn't known—spoke volumes about the silent watch she'd kept over her sister despite their outward estrangement.
"I think I've been approaching projection backward," Shirou said, watching her examine his work. "Focusing on creating perfect weapons when my real strength lies in preserving connections."
Rin moved her hand toward the blanket first, hesitating before her fingers made contact. When she finally touched it, her breath caught audibly. "She used to wrap herself in this while studying," she whispered, the academic tone entirely absent from her voice. For a heartbeat, she was just a sister remembering, not the Tohsaka heir analyzing. Then, recovering herself, she moved her attention to the teacup, magic circuits briefly glowing along her fingers as she assessed the construct with more familiar analytical precision. "The detail is remarkable," she said, though her voice remained softer than usual. "I can almost feel her presence in it."
"Sakura's whetstone wasn't designed as a spell component," Shirou explained. "It was a genuine gift—something meant to connect us even after she was gone. When she died, that connection was severed, and the stone couldn't maintain its structure without her."
Understanding dawned in Rin's eyes. "And you believe your projection abilities are similarly rooted in connection rather than combat."
"It would explain a lot," Shirou said. "Why I can reproduce certain objects with such precision, why the history of an item matters so much to the quality of the projection."
Rin considered this, her gaze returning to the floating blanket. With visible hesitation, she finally reached out and let her fingers brush against the fabric. "Our traditional magecraft focuses on manipulating the world according to our will," she said quietly. "But yours seems to preserve the world as it is—or was. Memories made tangible."
The observation resonated deeply with Shirou. In this moment, preservation rather than domination seemed to capture the essence of his abilities—a perspective that set his approach apart from traditional magecraft.
"In the world of magi," Rin continued, her voice taking on an academic tone that barely masked her emotional reaction, "such an ability would be considered impractical. Sentimental. A curiosity rather than a weapon." She looked up, meeting his eyes directly. "But I wonder..."
"What?" Shirou asked, noticing her hesitation.
Rin studied the fading outlines of the projections. "These objects carry more than memories. There's something else there—something that suggests your abilities aren't just about preserving what was, but perhaps..." She shook her head, leaving the thought unfinished. "It's late. We should discuss this another time."
She moved to the bench along the wall, suddenly looking tired. "I couldn't sleep either. After everything El-Melloi revealed today..." Her fingers absently touched her pocket where Sakura's charm rested. "I've been reviewing what he told me about the Grail system's design. There are aspects of the Tohsaka contribution that weren't included in the materials my father left me."
Shirou recognized her frustration—the feeling of learning too late about legacies that should have been shared earlier. "Anything specific that might help us understand what happened to Sakura?"
"Perhaps." Rin absently touched her pocket where she kept her sister's charm. "The containment structures within the Greater Grail were designed with redundancies—failsafes meant to prevent the exact kind of corruption that occurred when the Avenger was absorbed."
"But they failed," Shirou observed.
"Yes," Rin acknowledged. "According to El-Melloi, the Einzberns deliberately bypassed certain safeguards in their desperation to win the Third War. They created what amounted to a backdoor in the system." Her jaw tightened. "A vulnerability my ancestors never anticipated—or if they did, they never documented it."
The weight of inherited responsibility was evident in her posture, in the tension around her eyes. Rin had always carried the Tohsaka legacy as both honor and burden; now, learning of its imperfections, she seemed to feel its weight even more acutely.
"It's not your fault," Shirou said quietly.
"No," Rin agreed, though her expression remained troubled. "But it is my responsibility now. Understanding what went wrong, ensuring it never happens again—that falls to me as the last Tohsaka." She paused, then corrected herself with sudden, sharp clarity: "The last living Tohsaka."
The amendment hung between them, a reminder of all that had been lost. Sakura should have been there with them, should have had the chance to reclaim her birthright, to reconnect with the sister who had been forced to abandon her. Instead, they were left with fragments—charms and dust and unanswered questions.
"We should return to the flat," Rin said finally, breaking the moment of shared grief. "Classes start early tomorrow, and we need to maintain appearances."
Shirou nodded, allowing the last traces of his thaumaturgical energy to dissipate. As they left the practice room together, he found himself considering the parallel paths they walked—both dealing with inherited legacies neither had fully chosen, both seeking understanding of the past while forging their own way forward.
"Do you ever wonder," Shirou asked as they stepped into the cool night air, London's perpetual mist wrapping around them like a cloak, "if we're really in control of our own stories? Or if we're just playing out roles written for us generations ago?"
Rin was silent for several steps before answering. "I think," she said carefully, "that's the wrong question. We aren't fully free of our inheritances, but we aren't slaves to them either." She glanced at him, her expression thoughtful in the lamplight. "The real question is whether we have the wisdom to learn from our predecessors' mistakes without being bound by them."
It was, Shirou realized, another version of what Gray had told him earlier. Legacies shaped but didn't define. The past influenced but didn't dictate. In the space between inheritance and choice lay the true measure of who they would become.
As they made their way through London's mist-shrouded streets, the Clock Tower receding behind them like a watchful sentinel, Shirou felt something shift within him—not a resolution exactly, but a clarification. Whatever his father had been, whatever role Kiritsugu had played in the Fourth War, Shirou's own story remained unwritten.
And in that unwritten space lay both freedom and responsibility—the twin inheritances that would guide his path forward.
A/N: I don't normally like to use author's notes, but this chapter is very significant to me so I'm going to break my own rule for once. I'm not a professional writer, nor do I aspire to be. But I've always had a deep longing to tell this story. That's why I struggled for years trying to continue where I'd left off in my previous attempt at a Fate/Stay night fanfic, but it was like trying to grow a new tree out of a dead stump. Eventually, I realized I had to move on and let go. But letting go doesn't mean forgetting. You can hold on to your memories, learn from past experiences, and use the wisdom you learned to do better next time. Starting to sound familiar?
Chapter 5: Inheritance is the culmination of my 15 year writing journey. It means a lot to me. It's a mirror of my own bitter lessons and the fruit those lessons have borne. I want to acknowledge all the readers, and especially reviewers who have invested their time and attention into this story, whether they've been following me since the first chapter of Fate/indubinanter was published or if they only just discovered The Garden of Memories today. I enjoy reading reviews and I always welcome constructive feedback that's offered in good faith.
"Thank you" doesn't feel quite adequate, so I'll use "Arigatou," which is fitting considering where the Fate franchise originated. The kanji for "arigatou", which means "thank you" in Japanese, is written with two characters that convey a meaning of something like "this came into existence with difficulty." This is a beautiful acknowledgement that every gift you receive involves a sacrifice. It is also deeply appropriate in describing my struggles with creating this story. ありがとう, dear readers. Thank you.
