I do not own Fate/ Stay Night or Re:Zero this is a fanfiction only.

I guess my life has been always one tragedy after another. My name is Shirou Emiya and I was first unlucky when I was a kid, everything and everyone I considered family was burned to a crisp by an explosion that burned my home and five city blocks around it. I survived by what some doctors would call a medical miracle.

I was adopted by a man who at first I thought he was insane, he flat out told me his profession was being a mage. I don't know if my ever adventure seeking father was just pulling my leg, or he was indeed a mage that traveled around the world fixing situations that others considered impossible. To me, he was my hero, and I loved him dearly.

To all those around us we were indeed father and son, and the few times he was with me he taught me everything he knew about magic, except that since I was not his flesh and blood son I could not inherit the mark of the Emiya family.

The mark acted as a living record of all the magic every member of the family ever used or invented, but the only way to have it was literally to transplant it from his arm into mine, and thus I would inherit all the knowledge and the family magic circuit.

My father said that it was basically impossible for me to do magic of any level without a magic circuit, it was the part of a mage that collected mana from the air and would help me regulate the mana that was produced within my own body.

Quitting was never a part of our family way, and so I kept trying to form the magic circuit within myself. I kept trying over and over, with excruciating pain, and much disappointment. I kept trying until one day my father told me something he sort of forgot to tell me, that I needed to know how to activate the circuit if I ever succeeded in making one.

He gave me a weird tasting potion and I fell asleep, as opened my eyes, I saw a massive circuit breaker, almost like I was looking at a wall with dozens of switches, I didn't know what would happen, but I began to turn them all on. The room began to light up as I turned the switches on.

As the final switch was on I began to feel a new energy coursing through me, it was like a dam had been opened and water was flooding a previously dry riverbed. I opened my eyes and focused on the one item that father had given up hope of ever repairing. It was an ancient English sword that he called Calibur.

As I looked at the broken blade I began to look at it and analyze it. I could see everything about the blade, the way it was forged, the way the metal was constructed, I could see everything about it to the last detail. The last thing I saw was the damage the blade had endured.

As I placed my hands on it, I began to use this new energy and began to patch everything that I could see not fitting the original design. I poured it into the sword and little by little I began to fill in the cracks, dents, and missing parts. To me, it felt like hours of work, and I could not move from the spot, I just felt like I needed to make this thing perfect.

As the switches in my mind turned off, the blade dropped from my hands and it looked like it was brand new. The golden shine of the blade, the handle had an intricate design and it looked like something out of a fantasy noble.

I saw my father smiling, and I knew that he was proud of me. He hugged me and hand me sit near him. "That was magnificent work Shirou. I see my potion made you see the trigger of your magic circuit. Next is my final lesson Shirou, to be a proper mage you must train your body, and not just your magic. A healthy body for a healthy mind, so from now on you will train with me."

"Take up the sword you just repaired and with it, you will learn to fight using it. Make no mistake Shirou, I have been taking it easy on you since you had no magic circuit, but now that you can activate it. I will hold nothing back, you will train and I will teach."

From that day I began to train with father and he was not kidding, the training was hard and painful. I didn't care however since I got to spend time with my father. For five years I trained and perfected what I called my repair magic.

That was when tragedy struck my family once again, my father never told me but he was suffering from a very horrible illness. No doctor, mage or alchemist could tell him the cause of the disease, but the results were that the illness was causing his internal organs to slowly rot and this much to my surprise was causing him immense pain.

With a great deal of sadness, I buried my mentor, hero, and father. After he died I lost all interest in the outside world. For all intended purposes my world had ended. I knew father had many little investments so I was not hurting for money. A local Yakuza boss was actually in charge of handling his estate.

I received both money and groceries on a regular basis. I had become also quite good at cooking, cleaning and so I was quite self-sufficient. What little time I had after taking care of my household chores, I spent training my body and my magic. A friend of my father, who once I thought was his lover, came to invite me to attend a school she works at as a teacher.

I told her that I didn't have time to waste on things that I would never use, I had enough on my plate training to be a mage. She laughed and said that I reminded her of my father when I said things like that, "Shirou there is no such a thing as magic. Sure you father worked for many companies around the world, but there is no such a thing as a mage."

I was not going to let this person tell me my father had been lying to me. "Look, I understand that you are worried about me. I understand that you think I need friends my own age, and I know you are thinking of my own good. I, however, don't appreciate you saying that my dad lied to me. It becomes quite clear that since you are unwilling to see my world, then I should have nothing to do with yours."

I walked towards the dojo and began doing my training. She was not giving up, she walked into the dojo and picked up a practice shinai, a practice sword made of bamboo. She tossed me the practice sword and she took one for herself.

"Ok Shirou, you think you are so good with a sword, come at me. If you manage a single hit on me I will never bother you with this again, but if you can't hit me you give up this fantasy nonsense and come to school every day."

She must be kidding, I learned to fight using a real sword, and this bamboo practice sword was pretty much a toy to me. I only used it to practice the forms of combat. The real practice had been always done with the blade I repaired.

She tried to catch me unprepared and she tried to strike my head. I don't know why but out of sheer instinct I blocked her attack and hit her three times, one on her ribs, second on her shoulder and the final hit on her head.

She dropped the shinai and then began to cry as she knew I had beaten her. "Why did you have to hit me so hard Shirou, I will have a bump on my head for sure. I promised, so fine if you want to waste your life in your little fantasy go ahead. I will not tell you about my amazing school, the fun clubs it has, and the amazingly beautiful ladies that attend it."

To me, it sounded like she was still trying to get me to attend that school and all that had been attempts to get me interested in it. Of course next to perfecting my magic and becoming better at my other skills made her school rather plain and boring.

She, of course, was lying about not mentioning the school to me again, she came every single day to tell me how fun her work was, and how amazing the school was. The next thing she did was bring with her one of the students, and they pretty tried to do a tag team guilt trip.

I had enough, I was sick of her breaking her word and making fun of my father. "Taiga I am done hearing you say bad things about my father, I will never attend that school, and nothing you say will ever get me to change my mind. I will honor the traditions of the Emiya family and no one has the right to tell me otherwise."

She looked at me with fake crocodile tears, "Shirou I am only doing this for your good. You aren't even a member of the Emiya family. Your father might not have told you, but you are adopted. You have no reason to follow the path of that family."

That was the last straw, "Get up and leave, I never want to see or hear from you again. How dare you say that I am not a member of the Emiya family. You dare insult my father, and then attempt to get me to dishonor him. Get out, Get out now or I will accuse you both of trespassing into private property."

They both left I knew my father's friend was pretending to be sad, but the girl next to her was indeed sad. As soon as Taiga left I apologized to her and told her that the world where her school was simply was not my world.

"The actions of my father's best friend have reinforced what my father once told me. The world of the mundane is not my world. I am a mage and as such her world will never be mine. My family is not part of the magic association, and thus I must live in my own world even if I must live in it alone."

She looked at me with a rather concerned look on her face, "Shirou that is a very lonely and sad way to live. I hate to tell you this, but you might be a lone sword in death and in life if you live like that. I pray that one day you can be reborn in a world where you can find others like you who believe in all that fantasy stuff you and your father loved so much, maybe then you will find someone who will make you happy."

I saw her leave and much like I knew it would happen I never saw them again, in the end, the threat of being charged with home invasion was all I ever needed to be left alone, Taiga clearly feared that having a criminal record would cause her to never be a teacher for the rest of her life.

She might have said that she did it because she wanted what was best for me, but the bottom line she would always think about herself first. My training progressed as far as I could take it on my own. My magic could repair anything I could ever find. If anything I was feeling a bit bored, useless, and lonely. I guess you never value something till you lose it.

"You know it would sure be nice if I could go to the world where I could be useful, where I could feel like I was needed, a place I could be the hero my father was, and maybe just maybe find someone who I could be her knight in shining armor, and even find someone to fall in love with."

I must have been more tired than I ever thought I was, I suddenly felt very sleepy. I closed my eyes and kept thinking about the wish I just made. There is an old saying, "Be careful what you wish for or you might get it." I never understood what that meant. Little did I know that I would learn the meaning of that old saying rather quickly.
