Chapter One : Disorientation.

Waking up in a hospital was a new experience for me. As far as I could recall, I always healed fast. Broken bones rarely took more than two weeks to heal and cuts rarely lasted a week. So, it came as a surprise when my memory failed me on the events that led to me waking up here for the first time in my life. Looking at the EKG Machine, the saline drip and the catheter it was clear I was here for some time, probably in a coma. The writing in the EKG machine had both English and Japanese but that wasn't strange because my last memory was walking to the nearby 7/11 late at night to get some bento after working overtime at my job.

As I tried to summon up the memory of how I got there, a nurse came in through the door and gasped then ran back out screaming 'Sensei' or something along those lines.

Soon enough, an elderly man in a white medical coat came in.

"Ah! It's good to see you're awake. How are you feeling?" He asked before shining a light into my eyes and took my pulse with a stethoscope.

"I am feeling fine, I suppose. But where am I and how did I get here? I can't seem to recall any of it" At that he looked a bit morose.

"I am sorry to say that you've been in a coma for the last four years. You were a survivor of the Fuyuki Fires. While originally you were badly burnt but the doctors in Fuyuki noticed a strange phenomenon where your body healed unnaturally fast but you still remained in a coma. So you have been transferred here to Tokyo Medical University Hospital." He stopped for a moment letting it sink in before continuing.

"When you arrived here your body was in a pristine state, not even a scar on it which was beyond normal regardless of how sheltered a life a person lived. Not to mention we couldn't find anything about you and we searched everywhere and contacted both Japanese and Foreign embassies considering your Caucasian appearance but we failed to make any headway on that either"

The more he spoke the more concerned I became. For one thing, I was Asian the last time I checked, a mix to be precise and now I am suddenly Caucasian. And Fuyuki is the name of a fictional city, as far as I know. So, I listened as he continued on.

"Could you tell us your name though?" he asked.

"Uh..its Damien Grey. I am not originally from Japan and I last remember being in Kyoto as an Assistant English teacher" I said.

"Huh, what was the name of the school? We'll try to contact it"

"Well, its Kyoto Municipal High School and I am sorry I don't remember the number, it was saved in my cell phone. If you could give me a laptop I could open up my google account and download the phone list" I said.

He looked at me as if I was uttering nonsense. He finally asked.

"What are you talking about?"

"Google? The international company? The world's biggest search engine?"

"Isn't that some search feature for the internet? I am not very good with all this new technology" he admitted.

"….What year is it?"

"Its 1998, 7th of March" he said.

I think my brain shut down at that moment. It was nearly October of 2019 and now I am suddenly over two decades back? I still retained the acumen to not tell him what date I was from. That would increase the questions asked and may get secret government types involved more so than it probably already has.

"I see. I'd like to rest a bit if it's possible. This is a bit too much to take in right now" I said.

"Of course, we will continue this conversation in the morning. Please call the nurse if you need anything" with that he left me to my thoughts.

'Time travel was a bit beyond my expectations, if I were being honest and to find out I was in a coma for over 4 years was even a greater annoyance.'

"Shit" That was all I could say at the moment as I sat on the bed, with no choice but to stay there and stare out the window that was to my right. I wasn't hungry, despite not having solid food for years.

There was nothing I could do but wait for the morning. Checking my own body, I was in very good shape. Muscular with very little fat which is very strange considering muscles tend to atrophy when not used enough.

I tried meditating to see if anything changed about me. I had no idea what but all I could do was hope I could catch a glimpse of something or the other. As I looked inwards, I felt something shift in my head and then I opened my eyes to this.

[Skill]
[Intuitive Aptitude]

I knew what this was but I just couldn't believe my eyes. Rubbing my eyes and closing and opening them didn't make the status window for that is what it was disappear. It remained fixed in my vision moving in the direction of my eyes remaining centered.

"Well, that's new. SO, I suppose this is my Isekai power or something?"

I had already come to doubt that this was 'my' earth. First and foremost, the only fire I can relate to when I hear the word Fuyuki is the fire in the 4th Grail war from the Anime/Visual Novel Fate/Stay Night as there was no city named Fuyuki on Earth; trust me I googled that.

There wasn't much I could do right now, regardless of this power as I couldn't even get out of the bed with all these pipes stuck in me so I waited till morning unable to fall asleep without a TV and left only to my thoughts.

In the morning, the doctor and a nurse came to remove some of the pipes and it was every bit as uncomfortable as I expected.

"You're in remarkably good health, despite being in a Coma" The doctor suddenly said "Could you try standing up, but slowly. You've not used your legs for many years and may not be able to handle your full weight just yet"

I know that should be the case, but I felt normal and managed to walk just fine which surprised both the doctors and the nurse.

"Well, that is incredible." The nurse mumbled.

What followed that was a battery of tests to find that not only was I in good health, I was beyond normal healthy.

I wasn't released from the hospital just yet though. I had to spend a week in the hospital as the government still couldn't find anything about me so they couldn't deport me either. I was technically a non-entity on earth with no home country. I was questioned by Officials from the government about my previous country but I faked amnesia and got out of that.

I did find out that I was in the Fate/Stay night world when I read about the Fuyuki Fires and how over five hundred people died in the fire with there being only a few survivors. I was one of the two survivors who were found in Ground Zero. Not to mention I was about 19-20 years in appearance and had blond hair. Where before I was black-haired 28 going on 29 old man.

The skill I had though was a Godsend. I always could understand things without knowing why I knew what I knew but this was step further.

[Intuitive Aptitude]
Allows the user to instantly understand the workings and mechanics of anything, regardless of how simple or complex. They can comprehend the complexity and exactness of events, organisms, objects, subjects, fields, powers etc without needing long-term or special education or explanations.

It honestly was a bullshit power and now that I was aware of it, I could discern how things worked. I could even get a feel of how my organs are working how the technology around me was working, whatever I concentrated on I understood.

After being removed from the wires and whatnot, I started exercising to pass the time and found my stats increased when I did that. Albeit minuscule with .1 or .2 increase but there was an increase.

I tried to see if I could create skills, just to make sure and I certainly could. Observe was an interesting skill that showed me a persons health and mana along with their race.

The nurse and the doctors had average health of below 70 for most parts.

"Ah, Grey San you're up" The voice came from the door as the Nurse, Honda Yuuko entered the room bringing the morning breakfast. Following her was the doctor, Sato Noritaka. She put down the Food and left.

"So, Grey San it seems the government has decided to allow you Japanese Citizenship. However, you'd need to apply for a high school diploma by giving an exam in six months. Some officials would be coming to talk to you later and then you'll be released from our care" He smiled at that.

The government officials came later in the day, with passports and citizenship certificate. I was given naturalization since I didn't have a previous nationality and was in Japan for nearly 5 years. According to the certificates I was 20 years old. They even gave a temporary apartment and books to study for the high school GED exam.

The apartment I was given, wasn't bad. I was also being given 150000 Yen per month for food and other expenses as the housing was free.

As I read through the books, I found the concepts easy to understand. The only difficult part was the Japanese history which was annoying to remember. My practice in my magical skills turned out I could create skills, powerful skills if Needed as long as I understood the fundamental function of how things worked and with Intuitive Aptitude I understood how my brain worked. So I managed a skill to increase my memory recollection to nearly Perfect level.

[Pamnesia]
Allows the user to remember and recall everything that they have experienced, encountered and learned in their lifetime.

Thankfully, I could turn it off when I didn't need it. But when active I can simply go through a book and my 'Intuitive aptitude' helps me learn it instantly. Does the studying part was easily done and thus I started working towards creating more skills in the 6 months' time I had.

Turns out creating new spells aren't all that difficult. Elemental Magic was easy enough to create since I understood the concept being how the natural phenomenon occurs.

I also found I didn't need to eat so I saved a lot of the cash from the government in food and other expenditures. I had bought a computer but it was slow, so slow. I had forgotten how slow Dial-Up internet was. It wasn't even full of useful information as Wikipedia hasn't even started yet.

The first month was spent trying to create more skills that would be useful. Some of them I outright stole from the very fictional world I was in.

[Structural Analysis] [Reinforcement] [Tracing]

They worked exactly as they did in the series with the only caveat being, I could push Reinforcement to 100 instead of a normal 10 since Intuitive Aptitude helped me understand how far I could push my body without tearing it apart. Traced objects didn't get destroyed by Gaia for whatever reason though.

A combination of Structural Analysis and Electron manipulation allowed me another very useful skill called Technopath. Which was incredibly useful in hacking things I felt like as long as it was electronic in nature.

Joining a gym and exercising also showed a large increase in physical stats, so much so I had to quit and find alternate heavier things to exercise with but the results were worth it. Physically I had increased my base strength to near 10 times a normal human, INT wise it was a little less. My Exp didn't increase though, as apparently, I would need to kill things to gain that.

Learning Runes wasn't difficult but I could only find Eldar Futhark runes on the net. I didn't have access to any magical shops or whatnot.

"Maybe I should go to the Clocktower for a year or two?"

It was an option. But not right now.

The exam for the Highschool GED came soon enough and I passed it easily enough and got the certificate. Now, I won't be watched by the government anymore and could travel incognito.

There was still years before the events of the Holy Grail War and I needed to be strong enough. I doubt I'd get a servant but I could become as strong as one.

"Shiki Ryougi should be working right now in Garan no Dou"

I checked the Map to find Mifune City, which was actually near Tokyo so I could take a train there. What I wanted to do was find Ryougi Shiki and use structural analyze on her and see if I can understand how the Mystic Eyes of Death Perception Works.

Once reaching the city, I started looking for the Garan-no-Dou and was feeling incredulous when I could find it in the phonebook.

"Hello, is this the Garan-no-Dou?" I asked.

"Yes, it is. Is there anything I can help you with?" answered a male voice on the other side.

"Ah! I just wanted to know if the place was still there. This is the place of Touko Aozaki, right?" I asked to confirm it.

"Yes, it is. Were you looking for her?" He replied.

"Indeed. Please inform her I'd be coming over to meet her soon. Thank you"

"Alright, I shall inform Touko-San" with that I cut the call and walked off towards the Garan-no-Dou.

The place was still the same as in the anime. Walking up the stairs, I found the door to Touko's office on the fourth floor and pressed the doorbell.

The door opened to a young man opening the door, I assumed he was Kokutou. He looked different than in the anime but with the glasses and dress he felt harmless.

"Yes?" he asked.

"Hello, I called a while back about a meeting with Touko-san. Is she in?" I asked with a disarming smile.

"Yes, please come in" he led the way.

"Kokutou, who is he?" asks a girl who was dressed in a kimono with a red jacket, definitely Shiki. There was also a woman with long Auburn hair tied in a ponytail who was smoking up a storm and whom I assumed was Touko Aozaki.

"Ah I am sorry. I forgot to introduce myself. My name is Damien Grey, I hoping to meet you; wielder of the mystic eyes of Death Perception"

"Hooo, so you knew about her? And you came to me why?" Asked Touko peering over the desk filled with books.

"Well, it would be impolite to talk to her without talking to her employer. Besides she is no magi, so she couldn't be certain I do not mean to harm her without you vouching for me" I said.

"And what exactly do you want with her?" She asks now turning her chair towards me. Kokutou and Shiki are observing silently.

"I wish to use Structural Analyze on her and observe her brain to see how the Mystic Eyes of Death Perception works, that is all"

She looked at me like I was an idiot. Then sighed.

"That's not how Structural Analyze works, but fine. You can use it on her. I will keep watch" she said.

"Thank you. Do not worry Ryougi-san. You'll barely feel a tingling if you feel it" and then I used Structural Analyze on her by touching her hand was blown away by the amount of information I was getting.

I was watching the magic circuit connections to her eyes and how they were connecting her to her body to somewhere else, I followed that connection and encountered the Third Personality and then I found

「 」and screamed or assumed I was screaming.

It was nothingness. I was nowhere. I was everywhere. I was nobody. I was everybody. I saw nothing. I saw Everything. Information beyond anything I could understand tried to flow into me and I touched the Root for that was what it was. It tried to subsume me but failed and I was back in the room vomiting stomach acids on the couch and letting go of her hand.

I saw nothing. I understood it thanks to Intuitive Aptitude and I denied it. Two new notifications appeared after that.

[Mystic Eyes of Origin Perception]
Allows the user to see the flaws of all things including concepts and allows them to destroy it by cutting the Lines that represent the flaws in it.

[True Magic : Denial Of Nothingness]
Allows the user to manipulate the concept of nothingness to either bestow it on something returning it into nothing or remove it from a concept or idea or thought to bring it into reality.

All three of them looked concern as I slowly got up on my feet. Shiki and Touko were wide-eyed once they looked into my eyes. Touko got out of her chair and came rushing towards me.

"what the hell did you do, brat?" She asked while staring at my eyes.

"Touko san he looks a bit sick, perhaps he should rest a bit?" Kokutou tried to calm her down.

"Be quite, Mikiya kun. This is Magus business" She said sharply.

"Well, I said I wanted to understand how it works…so I did. And I gained the Mystic Eyes she had…and oh yeah, I am the new Magician of the First True Magic, surprise?" I tried to make some fake laugh.

"You..reached the Root in my Office by using Structural Analyze a basic spell on her and became a magician?" She slowly said.

"Yes? I expected to Learn to become a user of mystic eyes. But I didn't expect myself to become a magician that easily." I shrugged.

What else could I do? Just to prove it to her, I analyzed her smoke and recreated another pack using true magic. Unlike Traced objects that return to motes of ether when destroy, these were real and physical. I threw at her, which she caught and analyzed herself.

"Huh, this is a duplicate. So you do have that magic." She got down on the chair and started smoking ignoring us all.

I looked towards Kokutou and Shiki..

"So what do you do around here?" I asked.

That's how I met the Garan-no-Dou group and decided to stay there for the time being and hopefully learn basic magic from Touko.

This is not entirely a serious story. But something I am writing between long work days ~_~
The SI is extremely overpowered and will only get stronger. I will not drop this and write it as long as I can and see where it goes.

I don't have a Beta-reader so forgive any grammatical errors.
