Shinji didn't find it strange that Sakura would make such a choice.
Because of her own intervention, she didn't have that dark and unbearable experience, and her family's education of her was healthy and positive. Although she couldn't be so pure because of the cruelty of the magic world, her three views were generally positive. The legendary blackening, black cherry, etc., were only possible if someone killed Shinji in front of her.
Sakura would not ignore the dying person in front of her, even if that person is a Servant or a potential enemy. Shinji himself did not want Caster to die like this. Although she was a witch who had done many dark and cruel things, she was influenced by the arrow of the god of love. Her nature was not bad. The destruction of the workshop and the release of the trafficked women and children were the best proof of this.
Besides, there is no SoichirÅ Kuzuki in Fuyuki this time, no man who can save her and be saved by her, so someone should do something for her. Compared to myself who thinks too much, I obviously have a preconceived impression and tend to think too much, the simple and kind Sakura is more suitable to be the one to save her.
Therefore, Shinji took the initiative to take charge of the aftermath, leaving the task of investigation and tracking to Sakura, and also gave her the right to choose. No matter what decision she made, he would accept it.
And Sakura did not disappoint him. In the end, she came back holding Medea, the poor woman, and the four of them returned to the Matou mansion together.
So there was a scene where Wuhui opened the door and questioned someone based on misunderstanding.
After listening to Sakura's explanation, Fujino and Kirie were even more confused - it was already exaggerated enough that he picked up a woman after going out, but he didn't expect that the one he picked up was actually a Servant? This was too much of a coincidence.
"Whether it's a coincidence or something else, Sakura has been picked up. We can't just throw it back. Don't just stand here. Save people first."
After hearing what Shinji said, everyone took action. They said whatever they wanted, but since they had saved her, they had to save her to the end. As for how to deal with this "unknown" servant, they had to wait until she woke up and make a judgment based on her attitude and reaction.
Perhaps it was because the location of the Matou family had abundant magical energy, or perhaps it was because the healing rune that Sakura had cast was indeed very effective. After lying in bed for a few minutes, Caster woke up.
"Wow, am I still alive? This is..."
Her first reaction after waking up was normal, but when she saw the tall woman standing beside the bed, her expression changed instantly. Her hand instinctively reached out from under the quilt.
"Servant!!!"
With this action, the magic power in the room gathered towards her fingertips at an astonishing speed. Although she had lost her Master and might disappear at any time, as long as she was still alive and could move, she could release magic - just as she said, magic was just an instruction to her, and she didn't need to use her own magic power at all.
Her reaction was fast, and Medusa's reaction was not slow either. Her mission was to keep an eye on Caster and prevent any accidents. If an accident happened, she would not be polite and would directly punch him with her fist.
Although she is no longer a monster and has returned to human form, Medusa still retains some of the characteristics of a monster. One of them is strength, enormous power.
Not only does his own strength reach A, he also possesses a skill called "Super Strength" that can further increase his strength in a short period of time. Although he didn't use his full strength at this time, it was still terrifying. The power he exerted was enough to seriously injure the weakened Caster, and it was not impossible for him to kill him directly.
Fortunately, Sakura, who was also watching, stopped the fight between the two servants in time. Sakura shouted "Assistant", and the magic power drawn by Caster was dispersed by a stronger force and was not transformed into a destructive spell. Medusa's fist was also pulled aside by Sakura before it hit.
"Rider, calm down. Caster, please don't get excited. We have no ill intentions."
"That's right. If there was, we wouldn't save you at all. We could have just ignored you while you were unconscious, or even killed you." Wuhui, who was sorting things out at the side, said.
Ying continued: "We don't know what happened to you. If possible, can you tell us?"
"Oh, you're awake now. Would you like something to eat?" Shinji appeared at the door at the right time, holding a tray in his hand.
"The tea is ready." Shinji was followed by Fujino, who was holding a tea tray in her hands.
"Oh, it smells so good. Let me have a cup first. Add more sugar and milk." Kirie ran to Fujino.
"Is it my illusion? Why does it seem like Kirie is putting more and more sugar in it?" Shinji asked Fujino in a low voice as he watched Kirie add sugar to the pieces.
"It's not an illusion, she is indeed releasing more and more." Fujino replied in a low voice.
"Be careful not to gain weight if you eat something so sweet at night," Shinji warned.
"Huh, I hope to gain some weight, but no matter how much I eat, I never gain weight." Kirie said with a bitter face, words that would make at least 70% of women in the world jealous. She also took a piece of chocolate from the plate in Shinji's hand, and after a while, she took another piece.
"Eat slowly, save some for Caster."
Shinji quickly walked to the bed and handed one of the plates to Caster.
"How many? Although Servants don't need to eat, you've lost your source of magic power now. Eating something can replenish it a little bit and also change your mood. Good food can make people happy. I have always believed in this concept."
"this... "
Caster hesitated, and instinctively raised his hands and moved them near his shoulders. This action once again aroused Medusa's vigilance, but in fact nothing happened.
"Your coat is hanging over there. It's not convenient to treat you in that."
Shinji, who knows her well, knows that she wants to wear a hood to cover her plain face that looks like a lady next door, which doesn't match her devilish style. It is said that after being hurt by Jason, she likes to hide her face more and more.
"Don't worry, the one who treated you is my sister, Sakura. Next to you is her Servant Rider. This is Kirie, she made the bed you slept in. This is Fujino, she made the tea. My name is Matou Shinji, and I made the snacks, would you like to try some?"
Perhaps touched by the frankness of this group of young men and women, Caster stopped hesitating and reached out to pick up a piece of chocolate and put it into his slightly purple lips. After a few seconds, he whispered: "... Delicious."
"If it tastes good, eat more. There is also tea. Do you want black tea or milk tea? I recommend milk tea, which can replenish energy better."
"Um."
"Fujino."
"Right away."
...
In this way, under the sweets attack of Shinji and others, Caster gradually let down her guard. When Fujino poured her a second cup of tea, she finally asked that question.
"Why did you save me?"
PS: In FSN, Sakura's main R-sister's strength should be B. In this world line, Sakura's magic power is stronger and her attributes are further improved.
