Fuyuki is a large city with a population of more than a million people, and a river runs through it, dividing the entire city into two distinct districts, one side is a highly modern new town, and the other side is the old town with its historic charm and old town, and a bridge spans the river and connects the two banks.

This is a very ordinary city most of the time, but because of the special geology here, it contains a lot of magic.

So, every sixty years, Fuyuki City will become a battlefield, a battlefield where legendary heroes fight each other.

Heroes who have made a name for themselves in history, or gods and demons that have been passed down from mouth to mouth and mythical legends, will descend on Fuyuki City under the guidance of seven magicians and fight each other to win the highest honor.

And the reward for the ultimate victor is the 'Holy Grail' that claims to be able to fulfill any wish, peek into the origin of the world, and reach the root.

This battle is like a myth and legend, and it is called the 'Holy Grail War' by the people of the Dark World.

Recently, sixty years of reincarnation has arrived, and ambitious magicians have traveled to Fuyuki City in an attempt to obtain the legendary Holy Grail, fulfill their wishes, peek into the roots of the world, transcend the beginning and end of all things, and witness everything in the world, the past and the future.

However, there are only seven qualifications to participate in the Holy Grail War, and not everyone can participate, and if you want to participate, you must have a ticket, which is the 'Spell'.

Only those who have a spell on their body are eligible to participate in the Holy Grail War, and this qualification is random and will be picked by the Holy Grail, but most of them are magicians, but there are also examples of ordinary people who have been qualified.

But ordinary people participating in the Holy Grail War are basically dead and have no possibility of survival.

Those who possess the spell can summon legendary heroes and spirits, known as 'Heroic Spirits', and fight for themselves as their own servants.

And as the Holy Grail War approaches, the qualifications to participate in the Holy Grail War have been gradually distributed, and the chosen ones have already revealed the pattern of the Command.

Magician Killer;

Substitute for the Church Church;

Known as a prodigy, born in a family of nine generations of magicians, Miao Honggen is a genius magician;

The apprentice magician who is not valued, but is not willing to be ordinary;

The management of Fuyuki City, the patriarch of the Tosaka family of the origin of the three families, and a famous gentleman magician.

Those who have been chosen by the Holy Grail have already felt the oppression before the outbreak of the Holy Grail War, the calm before the storm.

"Fill, fill, fill, fill, fill, overlap five degrees at a time, discard when filled..."The magician's apprentice drew a magic circle out of blood in a dim corner of the park.

"Plain silver iron. The Covenant of the Ground Stone. My father, my teacher, was Bin Ogu. The surging wind is blocked by four walls. Close the Quartet Gate, release yourself from the crown, and wander at the fork in the road to the kingdom...", the gentleman magician closed his eyes in the underground chamber.

"Proclaim that Thou art under me, entrusting my fate to thy sword, obeying the name of the Holy Grail, and if thou wilt obey this will, respond to it." The magician's apprentice chanted.

"I swear that I am the one who accomplishes all the good deeds in the world, and Wu is the one who cleanses all the evils in the world!" The magician-killer takes an oath in the palace.

"Thy eyes are clouded, and thy heart is furious. A prisoner imprisoned by the Threshold of Madness. I am the manipulator of this chain! The second son of the magic family, in the dim cellar, said hideously.

"Pestering your three great words for seven days, come through the theory of suppression, guardian of the balance!!" The gentleman magician stretched out his hands.

Each magic array lit up with a dazzling light, and the image was different, but the only thing that was the same was that the existence with a powerful aura appeared in the center of the magic array.

"I ask you, are you my master......"

The moonlight was hazy, in a private house in Fuyuki City, because it was late, everyone in the family had already slept, and in the bedroom, there was a little boy lying on the bed sleeping soundly.

Suddenly, the back of the little boy's hand lit up, and a pattern resembling a lion's head suddenly appeared on the back of his hand.

"Ahh The pain woke the little boy up, and he made a painful sound.

"Shirou, what's wrong!?" The little boy's voice woke up the sleeping parents in the next bedroom, and the parents hurriedly ran over to see how the child was doing.

I saw that on the ground of the little boy's bedroom, a magic array appeared out of thin air, the magic array emitted dazzling light, a huge amount of energy spread, and the entire house shook violently, as if it had encountered a strong earthquake.

'Smack! The frames, the plates in the cupboards, and so on, were all shaken off and fell to the ground.

The little boy's parents also couldn't stand steadily, fell to the ground, and looked at the magic array in shock, when the fluctuations of the magic array disappeared and the vibration of the mansion was notified, a figure appeared in the magic array.

There was also a boy in the magic array, but he looked two or three years older than the little boy in the bed.

"It's you... Are you calling me? Caesar opened his eyes and looked around, and his gaze fell on the little boy on the bed.

"Shirou!" The parents who had fallen to the ground came back to their senses, let out an exclamation, and hurriedly ran to the little boy on the bed and held the little boy in their arms.

"Shirou? Emiya Shirou? Red A? When Caesar heard this, he looked at the boy on the bed in some surprise.

"You... Who are you, what's going on?" the boy's father, holding his wife and the boy behind, questioned Caesar in fear.

However, before the boy's father could finish his words, his voice stopped abruptly, and the boy's parents became dull, their eyes glazed over, and they were controlled by illusion.

"Tell me about you," Caesar said.

Through a simple understanding, Caesar figured out some basic information, this is Dongmu City, the head of this family is surnamed Kudo, his father is a lawyer, his mother is an ordinary housewife, and the child is called Kudo Shirou, who is still in elementary school, which is a relatively ordinary middle-class family.

"What did you do to my mom and dad, turn them back!" Shirou saw his parents, who had become like puppets and dolls, and shouted loudly to Caesar.

With Shirou's words, one piece of the lion's head pattern on the back of Shirou's hand disappeared, and the overall look was missing a third of the pattern

The next moment, Caesar felt an inexplicable restraining power, Caesar's illusionary control over the Kudo couple was lifted in an instant, and the Kudo couple's consciousness was clear.

“！！” Mr. and Mrs. Kudo woke up from a big dream, looked at Caesar in horror, hugged little Kudo Shirou, and trembled all over.
