(This chapter is mixed with some of the author's speculations, please don't take the party seriously)

When it comes to curing outcomes, there is no better cure than the HF line.

According to the plot, whether you choose the saber line or the Rin line, it corresponds to the sugar ending, but the Sakura line is different, this line reveals the purpose of the Holy Grail and the cruelty of the magic world.

The beginning of the Holy Grail War began with the Tosaka family two hundred years ago.

One day, the head of the Tosaka family discovers that a place called Fuyuki City has a leyline that connects to the Great Source. In order to obtain these magic powers, in addition to the special magic circle, it is necessary to open the key to the source of the magic power and the passage through which the magic power is exported.

The Tosaka family could not complete the huge plan on their own, so they invited the Einzberen family to make the Holy Grail, and the Maqiri family to develop a spell system to control the Heroic Spirit.

The leyline is the source of magic, the soul of the servant is the key to open the channel, and the holy grail is the channel that connects the source of magic. The feats that the Tosaka family could not accomplish were divided into three, making it possible for the wish to come true in a short time.

A careful analysis will show that the most important thing in the Holy Grail War at this time is the Master.

The Holy Grail summons the Servants only to obtain their souls, and the role of the Master is to provide the Servant's energy in the present world, and does not affect the Holy Grail Summoning Ritual in itself. Even if there is no master in charge of the command, and the servants who cannot be flexibly controlled are left to fight, as long as they die within the confines of Fuyuki City, the soul body will be recovered by the Holy Grail as the energy of manifestation and connection.

Before the rules could be fully set, the First Holy Grail War began in a hurry.

The first started in the form of a Call to Co-op. After the Holy Grail opened the source of magic power, the three families found that with their huge magical power, they could even allow magicians to communicate with the roots, and there was a certain probability that they would become the agents of the third law. As a result, the situation immediately evolved into a situation where the three families competed with each other, and the imperfect control of the Heroic Spirits became a destabilizing factor in this Holy Grail War, resulting in the final defeat of the First Holy Grail War.

After learning the hard way, the three families established new rules that have been used to this day. Before the Second Holy Grail War, the Maqiri family came up with a complete spell system, which finally allowed each master to fully control their Heroic Spirits three times.

The Second Holy Grail War had four more outsiders, and these outsiders were defeated by the three in just a few days. Outsiders hold a grudge and sabotage the Holy Grail War.

The Einz Belen, a millennium master who missed two consecutive chances to win, decided to cheat and summoned an eighth servant who was out of specification in the Third Holy Grail War, and the job was Avenger's Heroic Spirit Angola Manuel. Thinking that he would win the game, Einzberen unexpectedly discovered that Avenger was too weak to be even a normal magician, and was killed by other servants shortly after the Holy Grail War began.

The Third Holy Grail War also invited the home of Finnish magician Ederfeldt. The participants of the Edfeldt family are the current generation of Gemini, but unfortunately the younger sister of the twin stars was defeated and surrendered by Tosaka Tokitomi's father, and finally became Tosaka Rin's grandmother, whose sister thought that her sister was dead and thought that she had been deceived, and then withdrew from the Holy Grail War, and was extremely disgusted with the cunning Toei people, and this sentiment also continued to the next generation, which is the beginning of the evil relationship between Luvia and Tosaka Rin.

The Third Holy Grail War was still lost, and it was a spirit of collective wishes, and when he entered the Holy Grail, it was equivalent to making a wish for the Holy Grail, and after Tosaka won the Third Holy Grail War, the Holy Grail, which really had the ability to fulfill the wish, accepted Avenger's wish as the wish of the victor and activated its effect. As a result, Avenger, who is "all the evils of the world," received flesh in the Holy Grail and became the third dharma. It's just a pity that this third method is flawed, and the Holy Grail has not completely pushed him to the top.

Unable to escape from the Holy Grail, Angola Manuel finally became one with the Holy Grail and maligned his colorless magic.

If the defeat of the first two Holy Grail Wars was due to the rules, then the third Holy Grail War is human nature. The greed in human nature was the source of the tragedy of the next four and five wars, and Tosaka Tokitomi was only a promoter of the tragedy.

Without getting the Holy Grail, the magic fame Einzberen who was unwilling to fail thought that he was fully capable of leaving the other two families alone, so they were ready to recreate the Holy Grail. In the end, the damned old man of the Einzberren family came up with an ingenious way to forcibly seize ownership of the Great Chalice by means of a small artificial chalice.

Before the Fourth Holy Grail War, the Einzberren hired the fish-eyed mercenary Emiya Kiritsugu, and experimented with the Einzberen family's masterpiece, the android Alice Phil, on him.

The union of the two gave birth to Illyasfil, who was considered the highest masterpiece by the old man of the Einzberren family who participated in the third World War, and Illya's actions in the HF line ruined the Einzberen family's centuries-old wishes, and I don't know whether it was fortunate or unfortunate. Fifty years later, the thin-hearted Einzberen family decided to recruit a son-in-law. Emiya Kiritsugu is not a magician, but he has the title of a magician killer, and in the eyes of the world, he is a ruthless and money-conscious guy.

After participating in the Holy Grail War, the process turned out to be as expected. Kiritsugu did everything he could to eliminate his opponents, and even Director Ken, who gave up everything for love, was brutally killed. However, he is such a person, but he has a heroic dream in his heart.

"Kelly-san, what do you want to be when you grow up?"

"I want to be a messenger of justice. ”

In order to accomplish the righteousness of the world in his heart, he killed his father who gave birth to him and his adoptive mother who was educated and raised with the mentality that he could give up and sacrifice everything......

After he gave up everything, Emiya Kiritsugu finally saw the essence of the Holy Grail, the evil wishing machine that was polluted by the evil of this world and could only fulfill his wishes by destroying everything.

Driven by the righteousness in his heart, he forced the use of the Command Spell, asking Saber to destroy the manifest Holy Grail, and after the evil contaminated magic in the Holy Grail was out of container, it was completely uncontrollable, covering the surrounding land in a very short time, and the black mud in the sky swallowed all living things within ten kilometers, and tens of thousands of people died in this disaster, and the black mud passed through the grass without a single grass.

Kiritsugu, who did evil for good, collapsed, but before despair, God arranged for him to save a 7-year-old child. In order to revive the hope of atonement, Emiya Kiritsugu implants Saber's scabbard into the child's body. Unfortunately, on the way to save people, Emiya Kiritsugu's body had already been eroded by evil and died five years later.

Before he died, he left Shirou with a "curse", which Shirou, who had no future goals, gladly accepted.

Before the start of the Fifth Holy Grail War, the Einzberen family used the "Golden Holy Maiden" as the standard, and transformed Illya into a holy grail in the form of a doll, so as to control the Holy Grail to the greatest extent.

And Tosaka Sakura, who was sent to Makiri's house ten years ago, also underwent the inhuman transformation of Makiri's dirty inkstone in ten years, forcibly changed Tosaka Sakura's magic attributes, made a pseudo-holy grail, and placed his own body, the engraved worm, in Tosaka Sakura's body to control the Holy Grail.

The technical defect caused Sakura to have to endure great pain, from physical to mental, and Shirou, who appeared in front of her at this time, became the only light in her heart, relying on this light, she could spend one torturous night after another.

This is the true cause and effect of the Fate lineage.
