Chapter 1

In the dark basement of Matou residence in Fuyuki city, the ritual was taking place. A small boy about six or seven was lying down inside of a circle of runes and the black figure was standing reciting some incantation, and with each word the runes on the ground lit up one-by-one, and when every word in the circle lit up the body in the center rose in the midair and then a ball of light comes out from boys chest and then it flows up disappearing. After that, the room was illuminated by crimson light and near-identical ball of light was conjured right in the front of the boy and then entered his body of the boy instead of now gone the first orb of light, that was the original soul that belonged to the owner of the body, then the boy slowly descended to the ground. The shadow that was conducting the ritual stopped and slowly come closer to the boy. That figure was the boy's own grandfather Matou Zouken.

Zouken: Now let's check the results.

He slightly tapped the unconscious boy and just as he did that his face was distorted by anger but just as quickly it returned its calm.

Zouken: "So ritual has ended up in failure, well the idea to replace the Shinji's soul with another, so the new soul in order to better adapt to the body should have facilitated the growth of new magic circuits, unfortunately, Shinji's body ended up as a perfect host for any new soul inhabiting it due to inheritance trait that he got from his mother any new soul just inherits the body, that is already 287th attempt" Byakuya, take you son go.

And as he said that the new figure emerged from the shadow of the darkroom.

Byakuya: Father, is it appropriate to let this thing live?

Zouken: Idiot! We Matou never let life go waste, there is use even for the lowliest of bugs. Furthermore, if you ever bothered to properly study magicraft, you would have understood that ritual places the summoned soul of a recently deceased human in such way that it has access only to the memory stored in the brain, and don't have any access to his soul memory. So tomorrow when he wakes up, he will be indistinguishable from Shinji, he will act as Shinji and think that he is the Shinji. Obliviously as he grows up some personality traits from his previous life will slip through but generally, but he is Matou Sinji from now on.

However, the one thing that magus known as Matou Zouken did not consider, is the possibility of him making mistake while reciting an incantation. After all, the probability of such a ridiculous incident occurring is so extremely close to zero, that it would have been completely ignored by any creature that processes any resemblance of intelligence. But, by some unexplainable accident or maybe by the will of Fate itself that was exactly what happened. And as a result of that incident, the soul of still living person was summoned and placed into the body of Shinji, and due to that minuscule detail, the new inhabitant of little boy's body perfectly remembers his, previous life. However, right now none of the individuals in the room including now lucky or maybe unlucky transmigrator who's newly acquired body was held by biological father of said body.

Zouken: Now, go. Your stupidity irritates me.

Then the sound of closing door reverberated through the room signaling the leave of father and son duo.

Zouken: "One more failure huh. With the failure of this ritual, it can be said that there is really no way for Sinji to become magus and learn any form of magicraft. That means I will need to find a new child to inherit the Matou magic and continue the existence of my dying out family.

The Tohsaka head this generation has two daughters. With him being the prime example of modern magus, it would be easy but quite time consuming to persuade him to give his daughter to Matou family. After all, only one child can directly inherit the magic of his family. And every magus knows that it is a "great honor: to be the one who was chosen to inherit it. Heh, time what is one or two years in the face of almost 5 centuries, and those 5 centuries are nothing compared to the infinity of time. Just two hundred years ago in my 300th years of life at the age unattainable for the majority of mortal man, my goal was reaching Utopia and the death of Justeaze completely devastated me. Now mere 2 centuries passed and all my idealism as well as any feeling that I had for that woman that become grail faded away without leaving anything behind. And that is why I have to obtain it, the immortality no matter the cost!"

The next morning. In one of the rooms in the Matou residence, A boy woke up in the bed that technically belonged to him.

Sinji:" Yawns, good morning. Wait since when my hands are so short. Heh, that is not m room, where am I? Ah, It Hurts!"

And then at the next moment a great moment headache assaulted the boy simultaneously, images and different memories started to surface.

Shinji: "Am I Matou Sinji? NO!!! It can't be!"

Suddenly the urge to jump from the bed and start to search for any evidence that he hoped would have disproven his transmigration appeared in his mind. However, he was forced to stop his urge just as fast as it has come.

Shinji: "No. I can't be rush. If I am really in little Sinji's body, if I do something out of character, Zouken will not hesitate to use me as his lab rat. And even if is not my exact situation unknown and rush actions may lead to lethal consequences. Heh, I sound like some sort of novel protagonist, when I come out of this, I should decrease the amount of time that I spend on such novels. For now, lets quietly examine the room and simultaneously revise my memories maybe there is an answer."

Approximately 2 hours later.

Shinji: "I am really a Sinji now. The room is the same exact room from Sinji's memories and the corridor outside as well as the view from the window, all of them perfectly as my new memories. I even opened some of the books and discovered that no I can understand Japanese now. Heck, I even think using it. Not to say that I forget any language that I knew in the past. Actually, while examining my memories I discovered that I remember my past life too well. I remember everything from the moment I was born to the moment where I fell asleep only to find myself in my current situation. I remember exactly every book I read, every webpage I visited, every word I said even every thought that I ever had. The only things that I fail to recall are the Sinji's memories. I don't remember infancy, no every word he ever said. Well until today at least. I can even visualize the book that I just read to such a great extent that I can re-read just from my memories and the content of the visualized book will be 100 percent the same as the original one. Why do I have a such a perfect memory, is it a side effect of my transmigration? More and more questions are piling up. Form Sinji's memories I learned that he is almost 7 years old. And for the past 2 months, he was studying magicraft. Well trying to. Because just like in anime he has a zero potential for any form of magic and that sucks. According to my new memories, he always tried his best to learn it and according to my knowledge of his future, he will do so for the rest of his life. But no matter how hard he tries it will never be enough because he just has no talent. For a person like me who has grown up on shounen anime and manga like Naruto or One piece. Such a situation is beyond of just terrifying it is synonymous with despair. And that is the main reason why I did not hate Sinji when I was watching the anime. I strait up pitied him. Don't get me wrong he did a ton of terrible things especially to his poor little sister Sakura. However, every time I saw him, I thought I would have ended up in the same way as him or even worse if I was in his place. Knowing that there is real magic out there but you will never be able to reach it no matter how hard you try. That was one of the reasons why I hated Harry Potter as a child. It made me want to be a wizard but then said that it is impossible because you have to be born as one. It affected me so much that my life long goal was to become the scientist and inventor, after all the sonic screwdriver is not any bit less cool than a magic wand. And now I am in the same situation as one of the fictional character"
