11 Shirou excabades and Apprenticeship???

In the tranquil setting of the yard, Shirou could be seen surrounded by an array of sticks, metal pipes, and kitchen knives. The remnants of his reinforcement training were scattered around him. He had been tirelessly working on honing his magecraft, focusing particularly on his skill in reinforcement (because it was the lowest level of his magecraft-related skills except of course bounded field creation), which was currently at level 42.

With a determined expression on his face, Shirou meticulously examined the last item he had reinforced—a wooden stick. He had poured his prana into it, meticulously filling the gaps in its structure, seeking to enhance its durability and strength. Holding it above his head, he took a deep breath, fire could be seen entering his lungs feeling a surge of fiery energy coursing through his veins. With a swift motion, he slammed the stick forcefully into the ground.

A resounding thud echoed through the yard as the stick made contact with the earth. Shirou's gaze immediately shifted to the spot where the impact had occurred. To his surprise, a small crater had formed, resembling the size of his own head. His reinforced stick had left a noticeable mark.

However, upon closer inspection, Shirou's satisfaction faded as he discovered a visible crack on the surface of the stick. It was a reminder that despite his progress, there were still limitations to his abilities. A tinge of disappointment washed over him, but he knew it was all part of the learning process.

Feeling a wave of exhaustion washing over him, Shirou sat down on the ground, his mind drifting. The peaceful atmosphere of the yard allowed his thoughts to wander.

Shirou POV

Dad has been gone for almost four months, and I wonder when he will be returning. He never told me exactly where he went. As I ponder his whereabouts, memories of the time I looked at the park with my naked eyes flash through my mind. The clarity and intensity of my vision intrigued me, and I couldn't help but wonder if it would enhance my reinforcement abilities.

Deciding to try it out, I took off my blindfold, opened my eyes, and everything changed. The world around me slowed down, and each detail became sharper and more vivid. I could even perceive the vibrant colors of light around me and observe the tiniest particles floating in the air.

With this heightened perception, I focused on the experiment I wanted to try. Although Kiritsugu warned me against attempting something new without him, I convinced myself that it was merely an extension of my reinforcement training. I gazed at one of the kitchen knives lying nearby, analyzing its structure, weight, and history. This time, every detail was accessible to me, from the moment it was crafted in the factory to the purpose of its existence.

Drawing upon my newfound understanding, I channeled reinforcement into the knife. Due to my enhanced perception of time, the process felt like it lasted an entire minute, gradually infusing the blade with power. When I examined the knife again, I noticed glowing green lines encircling it, indicating the success of my reinforcement. Intrigued, I picked up a metal pipe and swiftly sliced through it with the knife. To my surprise, the pipe was effortlessly cleaved in half, as though I was slicing through soft butter.

As I marveled at my accomplishment, a floating holographic panel materialized before me, displaying astonishing information:

Skill:

Structural Grasp Level Up 61->87

Reinforcement Level Up 42->60

I couldn't believe my eyes. The progress I had made was staggering. It had taken me almost eleven months to go from level 1 to 42, but in a matter of seconds, I had reached level 60. Overjoyed by this newfound efficiency, I yearned to continue exploring my abilities. However, a tinge of disappointment washed over me as I realized that my prana should have been depleted by now. However, To my astonishment, I checked my circuits and discovered they were full, not overheating. It felt as if I possessed an infinite reservoir of prana to draw upon.

A realization struck me—I recalled a memory about someone called Gojo, someone who never ran out of energy. 'wait who is Gojo? Did Gojo possess these eyes before me? Why do I have knowledge of him?' The questions swirled in my mind, perplexing and confusing me. But before I could delve further into my thoughts, I acknowledged that time was limited with these eyes. I knew I would soon have to don my blindfold again. In a final attempt to harness their power, I activated King Crimson, my most costly ability outside of Lostvayne. A brilliant crimson-red aura enveloped me, radiating power as I exclaimed, "KING CRIMSON!"

Reality shattered around me once again. Everything seemed to slow down, and I found myself in a surreal space with a backdrop reminiscent of a cosmic void. The only visible entities were living creatures, almost frozen in their movements.

In this altered state, I turned my attention towards the house next door. I observed the bodyguards stationed around the perimeter, diligently patrolling their assigned areas. To my surprise, I saw Taiga holding what appeared to be a remote and singing? joyfully. Confusion filled my mind as I tried to make sense of the scene before me.

Seeking a moment of respite, I closed my eyes and focused on the state of my circuits. To my amazement, I sensed that they were generating more prana instead of depleting it. It was an incredible sensation, and there were no signs of overheating. Seating myself on the "ground," I decided to push the limits of this ability, curious to see if it could be leveled up further.

For what felt like an eternity but was actually only two minutes, I immersed myself in the flow of King Crimson's power. The system sent a notification directly to my consciousness, illuminating my face with a smile.

Skill: King Crimson has leveled up 4->5/20

Suddenly, a warm sensation trickled down my nose, and upon checking, I realized it was my own blood. It was a clear sign that I needed to deactivate the ability and don my blindfold once more. As I did so, reality shifted back to its normal state, and my heightened perception subsided. Thoughts raced through my mind as I pondered the duration of my ability. Curiously, the system relayed a message directly to my brain, confirming that King Crimson had been active for 2 minutes and 53 seconds.

Clocktower, England:

Unknown POV

After my weekly meeting(Trolling) with the vice director, I made my way back to my office. However, something inexplicable occurred. In an instant, I found myself seated in my office chair. It was a rare occurrence for me, someone who is accustomed to understanding and controlling every aspect of my surroundings. I pondered the situation, wondering if age was finally catching up with me. Yet, I couldn't shake off the feeling that there was more to it.

Perhaps Aoko was involved somehow, but why would she tamper with time in this manner? Curiosity sparked within me as I delved into my magical senses to investigate the state of the world. To my surprise, there were no abnormalities detected across the parallel worlds. This peculiar phenomenon seemed to be confined to this particular reality.

A mischievous smile formed on my lips as I entertained the idea that this might be an exciting new experience. I decided to embrace it and continued with my day, eager to unravel the mysteries that lay before me. Little did I know that this unusual occurrence would lead down a path of unforeseen events.

Souya City, Japan:

Unknown POV

As I strolled through the city, admiring the serene surroundings, an unexpected event disrupted my peaceful walk. Suddenly, I found myself teleported several meters away from where I had been standing. Perplexed by this sudden displacement, I sought refuge in an alleyway, creating a bounded field to ensure my privacy. With a sense of caution, I activated my magic to investigate the cause of this unforeseen occurrence.

To my surprise, I detected an anomaly in the timeline, a disturbance that piqued my curiosity. As I delved deeper into my magical senses to uncover the truth, a chilling realization washed over me. In that very moment, a white hand with green knuckles seized "me" and forcibly expelled me from the point in time I was attempting to examine. A voice resounded, proclaiming, "I shall not allow anyone, no matter who they may be, to peer into my ability! IF they try then I will eradicate every last one of them!" (Not Shirou saying this...)

My out-of-body experience abruptly ended, leaving me in a state of disbelief. Cold sweat trickled down my face as I absorbed what had just transpired. Swiftly, I hailed a taxi, determined to make my way to the train station and return to my workshop. There, I would unravel the mystery behind this unsettling event.

(BTW AOKO COULD SEE INTO THE TIME THAT SHIROU ERASED BY FORCE ITS JUST THAT SHE CANT DO THAT WITHOUT RISKING THE COUNTERFORCE TO GO AFTER HER BECAUSE EVERYTIME SHE USES BLUE THE PLANET AKA GAIA FIGHTS AGAINST IT JUST LIKE THE TIME SHE FOUGHT AGAISNT TOUKO THE PLANET DOESNT LIKE TRUE MAGIC BEING USED ON A LARGE SCALE THIS WOULD COUNT AS A LARGE SCALE BECAUSE KING CRIMSON ALSO AFFECTS FATE SO THAT NO BODY REMEMBERS ANYTHING MEANING THAT ANYBODY TRYING TO FORCE THEMSELVES AGAINST THAT FATE WOULD AUTOMATICALLY MEAN THEY WOULDNT FOLLOW THE LOGIC OF THE WORLD does that make sense?)

(if you dont like this outcome then tell me if you would like me to rewrite this interaction)

Fuyuki Japan

The next morning, Kiritsugu stood at the designated meeting spot in front of the train station in Mifune City. He looked around, scanning the crowd for the woman he had met yesterday. Soon enough, he spotted her approaching, accompanied by Shiki. They exchanged nods of acknowledgment, and without wasting any time, they made their way to the train that would take them to Fuyuki.

During the train ride, the atmosphere remained relatively quiet. Kiritsugu glanced out the window, watching the passing scenery, lost in his own thoughts. The woman, Touko, sat across from him, occasionally stealing glances at Kiritsugu. Shiki, as usual, maintained her stoic demeanor, her gaze focused elsewhere.

Upon reaching Fuyuki, they disembarked the train and hailed a taxi to take them to the Emiya estate. Kiritsugu looked out of the window, taking in the familiar surroundings as they neared their destination.

As the taxi pulled up in front of the Emiya residence, Kiritsugu stepped out of the vehicle, followed closely by Touko and Shiki.

Kiritsugu unlocked the front gate and led the way inside.

Kiritsugu's senses were immediately greeted by the aroma of a delicious meal as they entered the Emiya residence. The scent of Shirou's cooking filled the air, captivating their senses and making their mouths water. Kiritsugu's eyes were drawn to his son, who stood in the kitchen wearing his signature blindfold and a white apron along with a white shirt and black jeans.

Shirou had a focused expression on his face as he skillfully moved around the kitchen, tending to various pots and pans. he seemed to navigate with ease, guided by his instincts and well-practiced movements. The tantalizing smell of the food indicated that he had become quite proficient in his culinary endeavors.

Touko and Shiki, who were unfamiliar with Shirou's cooking abilities and the sight of him cooking blindfolded, looked on with confusion. Touko's eyes sparkled with curiosity, while Shiki observed quietly, her expression unreadable as always.

As the enticing aroma enveloped the room, Kiritsugu couldn't help but smile. "Shirou,I am back and we have guests," he announced, his voice carrying a bit of warmth. Shirou turned towards them, his blindfolded gaze focused in their direction.

"Ah, Dad you're back" Shirou greeted them with a polite nod. "Welcome back. Lunch will be ready shortly. huh who are they?"

Kiritsugu's response was direct and to the point. "They are here to help you with your eyes," he stated, his voice devoid of much emotion. Shirou's curiosity piqued, and he turned of the stoves and stepped out of the kitchen turned his attention to Touko and Shiki, giving them a polite nod of acknowledgment. "Thank you for coming," he said, expressing his gratitude.

Touko couldn't contain her intrigue and curiosity, her eyes gleaming with interest. She leaned in slightly, wanting to ask Shirou about his eyes before providing her assistance. However, before she could utter a word, Kiritsugu interjected, his tone firm and serious. He informed Touko and Shiki that they would need to sign a geas, a magical contract that would bind to their souls.

Shirou's brows furrowed as he processed his father's words. "What is a geas?" he inquired, seeking clarification. Kiritsugu paused briefly, choosing his words carefully. "It is a contract that ensures they won't disclose any information about you to anyone else," he explained, the gravity of the situation evident in his voice.

Shirou absorbed the information, his curiosity giving way to understanding. He nodded, accepting the necessity of such a contract. "I see," he responded, his tone calm and composed. He trusted his father's judgment and understood the importance of keeping his abilities a secret.

With a sense of determination, Shirou turned his attention back to Touko and Shiki. "If you're willing to help, then I appreciate it," he said sincerely, expressing his gratitude.

Touko's curiosity remained unquenched as she wasted no time in agreeing to sign the geas. "Let us proceed swiftly," she stated with a calm tone. Kiritsugu quietly chanted a quiet series of incantations, conjuring a paper that materialized in the air before them. The document outlined the terms of the geas, emphasizing the strict prohibition against disclosing Shirou's existence or revealing the whereabouts of both Shirou and Kiritsugu. Without hesitation, both Touko and Shiki affixed their signatures to the paper, sealing their commitment to the agreement.

Now bound by the geas, Shirou delved into a detailed explanation of his mystic eyes. He described how they overwhelmed his brain with an abundance of information, heightening his perception and he also told them how the eyes granted him the ability to use King Crimson for an astonishing three minutes without straining his circuits. Touko and Shiki listened intently, their expressions revealing their unfamiliarity with the concept of King Crimson. Nonetheless, they refrained from interrupting, allowing Shirou to share the full extent of his experiences.

Kiritsugu's initial shock transformed into deep contemplation as he absorbed Shirou's revelations. The implications of his son's extended usage of King Crimson, far surpassing his previous limitations of a few seconds, sparked a sense of astonishment within him.

Touko's eyes sparkled with curiosity as she observed Kiritsugu's reaction. Her inherently romaticist nature stirred within her, intrigued by the prospect of encountering a new pair mystic eye. She couldn't help but feel a surge of excitement at the opportunity to explore Shirou's abilities. (Touko is fundamentally a romanticist. Touko loves new things, and will tinker restlessly with things that she is interested in. this is canon btw check the wiki)

With a composed smile, Touko spoke up, her voice filled with measured intrigue. "This certainly piques my interest. A pair of mystic eye that increases its owner's perception to the point of overwhelming the brain with information? How fascinating. However, I do have to ask, what is this King Crimson?"

Shirou looked at Kiritsugu with a questioning gaze, seeking confirmation. Kiritsugu nodded, giving him the go-ahead to explain. Shirou took a moment to gather his thoughts before speaking. "King Crimson is an ability I have possessed for as long as I can remember. It allows me to manipulate time and erase specific moments."

Touko interrupted, her disbelief evident in her voice. "That's impossible! Only my sister possesses the Fifth True Magic."

Shirou's confusion was palpable as he tried to process Touko's reaction. Before he could respond, Kiritsugu stepped in to provide further clarification. "What Shirou said is true. While we don't understand how he came to possess this ability, King Crimson does have two distinct powers," Kiritsugu affirmed. "When activated, Shirou is enveloped in a crimson aura."

Kiritsugu continued his explanation, delving into the true nature of King Crimson's abilities. "The first ability is called Epitaph. With Epitaph, Shirou gains the ability to see the true path of the future, granting him glimpses into the events that will unfold for a few seconds."

"The second ability, known as Time Erase, allows Shirou to manipulate his fate and skip through time," Kiritsugu elaborated. "During a time erasure, he can remove the cause of events while preserving their effects. This gives him the power to alter not only his own destiny but also the fate of those he directly interacts with, within the affected time frame. It's important to note that these alterations are only perceived by Shirou and those directly involved, remaining unnoticed by others."

As Kiritsugu concluded his explanation, he emphasized of King Crimson's time-altering abilities. The concept of erasing time and foreseeing the future left Touko and Shiki in a state of heightened astonishment but they both looked skeptical.

Shirou then suggested, "I could show you." Extending his hand towards Touko and Shiki, they both cautiously took hold of it. As they made physical contact, a surge of energy pulsed through shirou body, and a crimson red aura enveloped them. Shirou yelled, "KING CRIMSON!"

In an instant, reality shattered around them. Everything seemed to slow down, and they found themselves suspended in the vast expanse of the cosmic void, surrounded by the serene beauty of space. Time appeared to distort, with living creatures slowing in their movements, their existence seemingly slowed to a crawl.

Touko's mind raced with disbelief. The sight before her defied all logic and reason. How could they be standing in the cosmic void, seeminly unaffected by the laws of time and space? It was an experience that challenged her understanding of the world and left her questioning everything she thought she knew.

Touko's gaze shifted to Kiritsugu, who appeared affected by the time-altering ability. Filled with curiosity, she reached out to touch him, only for her hand to pass through him as if he were a mere illusion. Shirou's voice broke the silence, explaining, "You can't interact with anything here, and nothing can interact with you. When King Crimson is active, your fate is temporarily erased, rendering you immune to any consequences or impacts."

Touko absorbed this information, her mind grappling with the implications. The concept of momentarily erasing one's fate was an extraordinary power, defying the rules that governed their existence. She felt a mix of awe and excitement at the magnitude of Shirou's abilities.

As the experience in the cosmic void continued, time gradually regained its flow, and reality began to reassemble itself. The crimson aura faded, and the surroundings transformed back into the familiar Emiya residence.

Touko withdrew her hand, her thoughts swirling with newfound questions and possibilities. The encounter with King Crimson had left an indelible mark on her understanding of magecraft beyond her previous knowledge.

Touko took a moment to calm down then said "well that was something...peculliar I will need to know more of this King Crimson ability so Shirou Emiya I will grant you a proposition... become my aprentice. If you do I will give you a pair of mystic eye blockers glasses something I made myself."

Touko's words hung in the air, capturing Shirou's attention. She extended an unexpected proposition, offering to take him as her apprentice. Shirou's eyes widened with surprise at the unexpected turn of events. He glanced at Kiritsugu, seeking his input, but his father's immediate objection was swift.

"No! That wasn't part of our agreement," Kiritsugu interjected firmly, his tone filled with concern. He understood the risks involved and wanted to protect Shirou from further entanglements with the moonlit world.

Touko met Kiritsugu's gaze with an unwavering resolve. Her eyes narrowed slightly, revealing her determination. "Ah, but you conveniently left out an important detail during our initial meeting," she countered. "I sensed the curse within your body, Kiritsugu. I noticed it back on the train, but I kept silent to satisfy my curiosity about the son of the Magus Killer. If you seek my assistance, an equal value must be exchanged. I wanted the help of the Magus Killer, not a weakened version of him."

(I dont know if you guys will like if shirou became an aprentice for touko so I am ending it here I already rewrote this ch multiple times the past two days trying to look threw countless wiki/reddit pages on touko aozaki to try and figure out her character to make a believable interaction between the emiyas and her tell me how I did and if I fucked up then I will scrap this chapter and restart)

(also I made it so that the six eyes also optimized the way magic circuits turn od and mana into prana so it not only reduces the cost of magic abilities but it also makes Shirou's magic circuits combine od and prana much faster let me know if you like this or not)

(anyways I am tiered as shit the fate lore is fucking convoluted as fuck in kara no kyokai touko helps out shiki just because that boy that works for her asked her to do so and in the other works she seems to be an entirely different f0king person from a cruel that believes themselves above everyone to nice person that values life)
