It’s not Shinji’s fault that he’s mentally unbalanced, it’s just because things are too coincidental.
The second magic of the old man with gem can observe parallel worlds. He also said that the Holy Grail created by the third magic is very important, so he will definitely not relax the monitoring of the Holy Grail War. It is impossible for him not to know about Shirou's abnormality - the act of crossing involves time and space, which is just within the range of his second magic.
However, he didn't say anything to Shinji and just threw him here, letting him participate in the Holy Grail War without knowing anything, and was eventually successfully tricked by another time traveler. It's hard not to think the worst of this behavior.
For example, he only needs one traverser in the end, so he uses the method of raising Gu to let all the traversers decide the strongest one. Or, the old man of the gem just wants Yustisa's soul to return to the uncontaminated Holy Grail. Thinking more deeply, the contract between himself and Yustisa may also be controlled by the old man of the gem, in order to use the characteristics of his soul to bring Yustisa safely to this world.
Of course, there is another possibility, that the old man was careless or Shirou was hiding too well, so he didn't notice the abnormality at first. But now, Shirou's origin has been exposed but he didn't show up, which can also be regarded as a kind of giving up - giving up the world line.
It's not that Shinji is pessimistic. This is not the first time that the old man has done this. In "Fate strange fake", he gave up a world line because of the early awakening of a big spider.
No matter which one it is, it means that he has reached the end of his rope, and the only hope he can place is the restraining force - Gaia, the restraining force that prevents the destruction of the planet, Alaya, the restraining force that prevents the extinction of mankind, and the restraining force responsible for maintaining the Holy Grail War itself.
The spokesperson for the first two is Observer Altria, and the spokesperson for the latter is Judge Jeanne.
The first one to take action was Joan of Arc. She bit her lip and stared at the boy who looked even younger than she was.
"Let me ask you again, Amakusa Shirou Tokisada, were you telling the truth just now?"
"You are so naive and cute, Joan of Arc, for still saying such things at this point."
Shirou smiled as if he was very happy.
"Well, since you said so, I will tell you that I was deceived. It was that woman, Semiramis, who seduced me, instigated me, and pushed the innocent me onto the path of destroying the world."
Semiramis, who was named, was not angry at all, but instead burst into laughter.
"Master, you are really—"
Shakespeare also laughed out loud, even louder and more wantonly than Semiramis.
"Hahahaha, interesting, so interesting. Master, it's a pity that you don't become a stage actor. Deceiving, tempting, and instigating are fine, but you actually say that you are innocent. Hahahaha, no, no, let me take a break and then write it down. Yes, I must write it down quickly. This is excellent material."
Well, there is no need for the human lie detector Karna now, everyone knows that Shirou is not telling the truth, even though the Assyrian empress who is good at playing with people's hearts does have the ability to do such a thing.
"Are you fooling me? Amakusa Shiro Tokisada!" A hint of anger appeared on Jeanne's face.
"Yes, yes, I am just teasing you. If you are unhappy—"
Shirou hooked his finger at Jeanne as he spoke. That exaggerated movement and funny expression made her look like she deserved a beating no matter how you looked at her.
"—Come and hit me!"
Then there was a "thump" sound - don't get me wrong, it wasn't that Shirou was knocked down by Jeanne, or that Shirou knocked Jeanne down, but that Shakespeare was laughing so hard that his whole body was twitching and he rolled down the stairs.
This little episode did not affect Jeanne d'Arc. The moment she confirmed Shirou's true intentions, she had already made the decision.
"Amakusa Shirou Tokisada, you have violated the rules of the Holy Grail War. You are my enemy."
"So, what are you going to do?" Shirou remained calm.
The Saint of France proclaims with a clear voice:
"In the name of Ruler Jeanne, I issue an order through the Command Seal to all Servants gathered here! Defeat Amakusa Shiro Tokisada immediately!"
The Command Seal engraved on the back instantly emitted a strong light.
Black Saber Siegfried, Black Archer Chiron, Black Lancer Artoria, Black Caster Avisbronn, Black Assassin Matou Shinji, as well as Red Archer Atalanta, Red Lancer Karna, Red Rider Achilles, Red Caster Shakespeare, and Red Assassin Semiramis were all restrained with chains.
The chain restrains the behavior, that is, the ability of the servant will be improved when Shirou is defeated. However, once he attempts to fight the opposing camp, his movements will become sluggish and the power of swinging weapons will be greatly weakened.
In this case, it is obvious who to fight. Moreover, most of the people present are heroes, and fighting against the evil people who intend to destroy the world is their duty.
"I won't let you destroy the world!"
Atalanta drew the bow as quickly as possible, and the arrow on the bowstring was filled with chilling hostility.
Her will is very pure. She hopes that all children can be happy, and for this a beautiful world is necessary. But now someone wants to destroy the world. How can she tolerate this!
Achilles was not slow either. He had long felt that there was something wrong with this priest, and this time he finally showed his true colors.
The two fastest servants in this battle almost simultaneously aimed their weapons at Shirou's vital points. However, before they could formally launch the attack, the two suddenly bent their knees with a distressed expression and stopped their movements.
"Ugh... what's going on...!?"
"Is it the Master...!?"
No, not only them, but also Semiramis, Shakespeare, and Karna.
In other words, all the servants on the red side became extremely weak at the same time.
"What on earth did you do?"
Jeanne's face was filled with confusion and the black servants also stopped attacking due to the unusual situation.
The boy being questioned chuckled, then unbuttoned a few buttons on the collar of his monastic robe. Everyone couldn't help but gasp when they saw his exposed collarbone.
Crimson Arcer, Crimson Rider, Crimson Berserker, Crimson Caster, Crimson Assassin - except for the one stroke used to restore the katana just now, there are a total of seventeen strokes of Command Seals, arranged neatly.
"Amakusa Shiro Tokisada... What did you do to our Master!?"
Although she was in a weakened state, Atalanta's eyes were still as sharp as a beast's, and she looked as if she was going to bite the opponent's throat.
"It's the former Master, right?" Semiramis replied nonchalantly, "Who knows? Maybe we can find some remnants in the Dragon Wings' lair now."
"You bastard!!!"
