Justisa was born as an android, and she has the nature that most androids have when they were designed, which is very obedient and very subjective. Whether it is completing the Holy Grail or saving the world, it is actually the mission given by the Einzbern family, not her own wish. Even though she was influenced by the soul of the hero and signed a contract with Shinji, her nature did not change much. Except for the persistence engraved in her soul, she basically listened to Shinji.
However, this time no one gave her orders. Shinji was resting, Scathach was racing, and Justisia made the decision entirely on her own will - this is a human's autonomous choice, a human attribute, and what Shinji most wanted to see.
In comparison, the chain reaction caused by this to Emiya Kiritsugu and Einzbern is nothing at all. At most, the two sides will fight. Shinji doesn't believe that Scathach and Lancelot will not be able to deal with a mere Einzbern!
Of course, before that, he had to find out the reason first.
"—Now, answer me, Justisa, why did you save Irisviel?"
"I... "
"I... "
"I have no idea."
Three times in a row, an answer that doesn't count as an answer.
Shinji understands this, because sometimes the body reacts faster than the brain. However, when you take action, you actually already have the answer. The only difference is whether you really don't know or don't know how to express it.
"Because you don't want anything to go wrong with the Holy Grail?"
"No." Justisa shook her head. "As long as the core of the Holy Grail is still there, it will not affect the ceremony."
"Is it because you want to help the Einzbern camp and don't want them to leave so early?"
Irisviel is a disguise put forward by Emiya Kiritsugu. If she dies and Saber is still alive and well, it will prove that she is not the Master, and Emiya Kiritsugu's existence will be exposed, which is not good for the Einzbern camp.
"Not really." Justisa still shook her head, "I've said before, I'm very disappointed with Yahad and the Einzbern family."
"Then the answer is obvious. It's not the Einzbern family, it's not the Holy Grail, it can only be Irisviel herself, am I right?"
Justisa was speechless. She didn't want to admit it, but she couldn't deny it either, because she had realized that the person she wanted to save was the being named Irisviel. It had nothing to do with the Holy Grail, it was just the personality of Irisviel.
"Tell me in detail how you felt at that time." Shen Er pushed himself up and sat directly on the experimental table, encouraging the confused "Winter Saint" with a smile and eyes.
"I... I don't know what happened. When I saw Irisviel trying to stop Kotomine Kirei, I forgot everything. I just thought that she couldn't die and I should save her. When I calmed down, I had already left the castle and stood in front of Kotomine Kirei. Shinji, am I broken?"
Justisa thought of the garbage dump of the Einzbern Doll Workshop, where countless broken or incomplete dolls were waiting to die. Was her precious prototype going to become the same as them
"Broken?"
Shinji didn't continue looking at Justisia, but turned to Scathach, and found that Scathach was also looking at him.
The two looked at each other for a few seconds and laughed at the same time. Scathach's laughter lifted a corner of the veil, revealing her delicate and plump lips. Shinji covered his stomach and kept patting the experimental table under his butt with one hand.
"Wait, wait, why are you laughing?"
The laughter of the two made Yustisa feel confused for a while, and her heavy mood also lightened a lot.
"It's nothing, you're right, you are indeed broken as a cyborg." Scathach smoothed her veil, and her eyes regained their usual indifference and wisdom.
"However, the malfunction of artificial humans is a normal thing for humans. Every human has the desire to protect someone or cherish something. Do you remember when I killed Zōken a year ago?"
Shinji slapped his face and tried to look serious.
"Remember, that's the condition of the contract you made with me." Yustisa didn't know why Shinji said this now.
"To be honest, that wasn't the best time. The best time would have been to lurk nearby and wait until Sakura had completed her transformation and Zōken's brainworm was ready to enter her body. But I didn't choose to do that. Do you know why?"
This time, Shinji didn't wait for Justisia to answer, but gave the answer directly.
"Because, Sakura's body and mind will be traumatized, and that trauma will be enough to make her live in the shadow for the rest of her life. When I first saw Sakura, I regarded her as my family. I don't want Sakura to become like that. I hope Sakura can live happily, so I choose to stand in front of Zōken before everything becomes irreversible. This feeling prompted me to make this decision, and I think you are the same as me."
After hearing Shinji's personal testimony, Justisa seemed to have grasped something in an instant.
"I think my feelings towards you and you in wanting to protect Sakura are different. Sakura is your sister, and we have a family relationship. I don't have such feelings towards Irisviel. I think I like her so much because I have doubts about her as a person, yes, a 'person'. I want to get the answer from her, the answer to how a doll can become a 'person'. Before I get this answer, I don't want her personality to disappear."
"Giving because you want to get something in return is also a human emotion." Scathach gently placed her hand on Justisa's shoulder, "Your actions prove that you have changed from a 'puppet' to a 'human'. You don't need to look for answers from others."
"No, it's not enough." Justisa pointed to her heart, "This place is not complete yet. Maybe she can let me know what I'm missing?"
Scathach wanted to say something, but saw Shinji waving his hand at her, signaling her to stop talking.
It is human nature to feel that it is not enough and to want more. Isn’t it the driving force behind human progress to continue exploring with this attitude
Scathach understood what Shinji meant and took Yustisa's hand: "Let's stop here. If you have any questions, we can think about them in the morning."
"Yes, yes." Shinji agreed repeatedly, "You haven't rested at home for several days. Go back to the room you haven't seen for a long time, have a good sleep in the bed, and eat the breakfast made by Sakura. It's not too late to think about it. Sakura has told me many times that she misses you and she will be happy to see you."
"Well, then have a good sleep." Justisa nodded vigorously, "Sleep is also one of the most basic elements of human beings."
"Then Shinji, I'll leave the cleaning here to you."
"No problem, leave it to me."
After getting Shinji's answer, Scathach and Justissa walked out of the workshop hand in hand.
One black, one white.
One light, one shadow.
