At the climax, tragedy becomes the main theme of the animation.

Sakura has a real relative by her side, Rin, and Shirou, who loves her more than thousands of people, and she is completely integrated into the life of Emiya Mansion and becomes a part of this small family.

However, happiness and contentment are only short-lived.

Sakura's body has been transformed into a grail vessel, and her body will also have the same conditions as Alice Phil, with weakness and deterioration of human functions, and it is difficult to even move a single step later. Even so, she still smiles happily every day. For her, everything she has now is something that she only dares to think about when she dreams, and after experiencing it herself, she is so warm, so happy, and so reluctant......

But seeing Sakura's body getting worse day by day, Shirou and Rin felt uncontrollable sadness. What happened to Sakura was irreversible, and as the Holy Grail War progressed, her health would get worse and worse until she lost her human form and became the Holy Grail. But the two of them didn't say anything, they just stayed by Sakura's side every day, giving her the happiness and joy she expected.

After Sakura sleeps, Shirou and Rin go out on patrol at night, only to find that the entire street is consumed by an unknown black shadow. Then the shadow meets Gilgamesh, who is severely injured and swallowed by the shadow because he is not aware of it. Gilgamesh, who appeared as the boss in the other lines, received a bento box with chicken legs from the director at the beginning of the climax of the HF line. And this serious injury made Sakura realize one thing, it turned out that she was the black shadow, and everything in her dream was done by herself.

What Sakura didn't expect was that everything she was experiencing and thinking now was under the monitoring of the old bugs.

The old bug arranged for Sakura to overhear the conversation between her sister Rin and Shirou many times, which stimulated the anxiety and inferiority buried deep in her heart, and also stimulated the shadow buried under that bright smile - jealousy.

The Holy Grail War is coming to an end, and Sakura is becoming more and more unable to control herself, originally she wanted to be given death by her beloved, and she wanted him to always remember her thoughts, but Shirou couldn't do it at all.

Sakura, who feels like her life is coming to an end, decides to break off with the old bug. So she used the last spell, asking Rider to stand by Shirou's side no matter what happens in the future or who he faces, and protect him on her behalf until the last moment of his life.

Let Rider become his own form and stay in the Emiya Mansion, and return to the Twin Mansion alone to question the old bug. The old insect who knows everything about Sakura's every move has arranged for Shinji to guard the gate.

Shinji, who was burned by jealousy and desire, tried to rape Sakura, and verbally insulted Sakura while tearing it up, and at the same time, the old bug controlled the marking worm to torture Sakura's body and spirit, and the unsustainable Sakura was completely blackened under the inducement of the old bug, tearing Shinji who had been insulting him.

Later, in order to get the Holy Grail, he personally came to the Guardian Mansion to snatch Illya.

Rin was defeated by Kuroka Sakura, and when Rin was about to be killed, Shirou arrived, and he stood in front of Rin, ready to use his body to persuade Sakura to turn back, but Kuroka Sakura completely ignored the fact that the man in front of him was the only light in his heart, and he wanted to do something to Shirou. Fortunately, the previous order to the rider saved Shirou's life.

Shirou is the only flaw in the blackened Sakura, and as long as Shirou dies, Sakura's heart will fall into darkness forever and completely sink. However, this spell finally preserved the last trace of her humanity, and she would still waver when facing Shirou.

Rider can't make a move on Sakura, as long as the blackened Sakura doesn't hurt Shirou, everyone can only ask for her. So, Illya stood up and volunteered to go with her.

The main theme of the ending is tragic, and the secondary theme is redemption.

Qili's lolicon soul awakened, and he personally found a team with Shirou, and while the blackened Sakura was in the pain of being eroded, the two rescued Illya.

The old bug chased after Hassan with the curse wrist, and Qili asked for the queen. He showed his inhuman strength, and he did not fall behind against the two of Curse Wrist Hassan and Old Bug, and even used the abnormal physique modified by black mud to trick Curse Wrist Hassan into revealing loopholes, luring him to use the Treasure Phantasm - Delusional Heart Sound, and then took the opportunity to kill the old Bug's body.

After bringing Illya back to the Guardian House, she tells everyone about the Black Grail. At this time, the black Sakura squeezed the remaining part of humanity into the black shadow of the past, and this black shadow came to the Emiya Mansion and told the three of them to run away quickly, because she didn't know when the body would lose its nature. Shirou firmly stated that he would save you, and Rin said that for the glory of the Tosaka family, he would definitely get the Holy Grail and kill you.

Before the decisive battle, Shirou, Illya, and Rin found the blueprint of the gem sword and made the legendary dress, and the three agreed that Rin and Kuroka Sakura would make the final touch.

On the other side, the old bug's body was destroyed, and he was ready to seize Sakura's body that had been prepared for ten years, but he didn't expect that Sakura at this time was already out of his control. And the body of the old insect that was about to move was also felt by Sakura, and she pulled out a disgusting, fat and ugly insect from her heart, that is, the parasitic body of the old bug, it was thrown to the ground, and it was crushed to death by the blackened Sakura like an ordinary person raising his foot and stepping on a dead cockroach.

The final episode of Armageddon. Shirou takes Rider and Rin to Yanagidong Temple, and the three of them face the magical Black Saber.

Black Saber let Rin go as agreed, and blocked Rider and Shirou.

The curry stick, which was once used by Saber as a trick, has become a small skill in the black hairless hand to read the long CD and not consume blue, and the black dark torrent roars and rushes in the air, like the black ominous pouring of the light of the world from the tip of the sword, as if the person holding the sword is the invincible goddess of war.

At this time, Rider finally used all his strength. She removed her blindfold, revealing Petrified Eyes. This magic eye can suppress the black hairless first-level attribute with a magic power level of A, and Rider and Black Saber are evenly matched. When the two were about to fight each other, Shirou projected the Blazing Sky Cover Sevenfold Ring to block the curry stick for Rider, but Black Hairless was hit hard by Rider's reins.

Shirou recalled what had happened to him and Saber, and while the black hair was gone, he stabbed the projected shogun into her chest with tears, and the tip of the sword pierced through her heart.

On the other side, Rin, the owner of the gem sword, the strongest dress in the world and a replica of the second method, and Sakura, who was given the half-finished third method by the Holy Grail, start fighting.

The two are inseparable from each other by the Houshan Pond, but Sakura always summons black monsters to harass Rin, causing Rin to gradually fall into disadvantage.

Rin threw out the jewel sword and exploded, creating a wonderful opportunity for her to get close to Sakura, but she couldn't do it when she was close to Sakura, it was her sister, so that she could give the precious gem left by her father to a "stranger" to use, her favorite sister, the sister who hoped to be happy, and the sister who looked forward to laughing at life.

"I gave you a ribbon, you wear it all the time, and I'm very happy. ”

Rin walked out for the time being.

Sakura, who is pulled back to the light by Rin, begins to resist the black shadow's control and even wants to commit suicide. Shirou, who arrives, tells Sakura that Rin is not dead. After that, he first projected the talisman of Ten Thousand Rings to break the connection between Sakura and the Holy Grail, and then used the only remaining magic power in his body to resist the strong backlash brought by the Heroic Spirit's body with the human body, and projected a curry stick to destroy the Holy Grail.

This blow contained Shirou's vitality and willpower, and this will made him stand in front of Sakura even to death, shielding her from the wind and rain.

Rin takes Sakura home, and Sakura, who wakes up from the nightmare, thinks that everything in her memory is a nightmare, as soon as she opens her eyes again, the senior will appear in front of her, laughing and telling herself to get up for breakfast, but she searched all possible places, but she couldn't find him.

She knew the nightmare was real, but she had a smile on her face. Smiled and rejected my sister's decision to live together, smiled and moved into the house where he once existed, smiled and planted flowers and plants, smiled and faced every spring when flowers bloomed, and said with a smile: "If you don't come back, I'm going to be an old woman......"

But day after day, year after year, there was still only the woman in that mansion, who was still smiling, and she was smiling at the arrival of the next spring.
