First of all, it should be made clear that although the world where Shinji lives is an "experimental flask" world that integrates various special elements (required by the plot), there are still many elements (plots) that cannot be integrated due to timeline conflicts, such as the Holy Grail War in Romania and the elements of "Magical Girl Illya".
Although that world has many similarities with the world Shinji lives in, there are fundamental differences that cannot be reconciled. In that world, there is no Einzbern family, but instead there is the specious Ainsworth, and what is hidden in Fuyuki is not the Holy Grail, but Sakutsuki Miyu, a "son of God" similar to Meline Solomon.
The Illyas of the two worlds are also very different, from their origins to their ages. Although they can both transform into magical girls because of the personal interest of the old man, the Illya of this world does not have the skill of "Dream Summoning" which replaces "Heroic Summoning", and the staff she holds does not carry the mouthy simulated personality named "Ruby" - the mouthy personality "Ade" is enough.
In contrast, Illya in this world does not need to bear the responsibilities of that world, does not need to run out at night to collect cards, and does not need to fight with Ainsworth. At this time, she transforms only to practice magic in a wider place. It is inconvenient during the day, so she can only practice at night.
At first, he learned the Einzbern alchemy from Yustisa and his mother, then the magic transformation and manipulation taught by the old man of gems, and later the adjustment of the soul taught by Shinji and Orange.
Finally, it was the highlight, the magic sparring with his mother, Irisviel.
No matter how many times I watch the sparring scene, Shinji will always think of the scene in the early part of Journey to the West where Sun Wukong fights Erlang Shen. You turn into a sparrow, I turn into a hungry eagle, you turn into a water snake, I turn into a gray crane. Of course, in the case of Illya and Irisviel, it is not the metal wires they manipulate that are changing, but the metal wires they manipulate. It looks very interesting.
The problem is that Shinji was watching with great interest. After all, he had a lot to do with the fact that the Emiya family could get to where they are today. He was sincerely happy to see the mother and daughter loving each other. Why was that weird woman watching so intently
Shinji knew the network of relationships of the Emiya family very well. That woman didn't match any of them. If she was a long-lost relative, Kiritsugu's father and adoptive mother were all killed by him. Maiya was an orphan from the battlefield, and her only child had not been found yet. Could it be the one in front of him
If I remember correctly, Maiya's child Sigma knew about his mother and Kiritsugu. In the original world line, Kiritsugu and Maiya died early, so they didn't come to find him. Now that they are alive and well, if they come to find him, the black hair can also match.
However, Sigma is not a woman but a man. Is it a gender change caused by the deviation of the world line? Or is Sigma a cross-dresser? He likes to wear women's clothes and even has breast pads
Well, the above is pure Shinji's nonsense, and the possibility is basically zero. Those red eyes are not what normal humans should have. It would be better to say that it is Maiya's child than to say that it is Irisviel and Kiritsugu's child. After all, he has black hair and red eyes.
Wait, red eyes? In addition to vampires, there is another possibility - Einzbern's artificial human. Now is the critical time for the activation of the Greater Holy Grail. It is normal for Einzbern to send people. It is not impossible to start surveillance when they find that Irisviel and Illya, the traitors from ten years ago, are not dead.
Although the standard configuration of androids is silver hair, the hair color can be easily changed, and Einzbern's androids also give people the feeling that they are not human. Could it be that I was wrong at the beginning? Continue to spread this idea - no, there are too many possibilities.
The more he analyzed, the more confused Shinji's mind became. In the end, he simply gave up thinking. Anyway, she had been targeted, and no matter what she planned, there would always be a day to act. Before that, he just had to wait patiently.
Patience is something Shinji has in abundance, and Fujino and Kirie have even less of it. If they didn't have patience, they wouldn't be willing to wait by Shinji's side all the time.
Two people and one "ghost" (virtual body) maintained a two-up-one-down posture, monitoring silently.
Until the mother and daughter stopped practicing and ran back to the room hand in hand.
Until the woman came down from the wall and left without saying a word.
Shinji and the others were completely speechless. The three of us didn't go home or sleep at night and ran out to follow you for such a long time, but you just watched the "magic show" on the wall and enjoyed the night breeze for more than an hour
For a moment, Shinji wanted to just grab the person and save himself the trouble. But he just thought about it. He had been following for such a long time, so he didn't mind following for a while longer. At worst, he could just go to the school rooftop and sleep tomorrow. That's what Japanese high school students do.
Unlike when she came, her eyes were wandering. When she left, her eyes were focused and she didn't look sideways. Her movements were also much faster than when she came. Her gradually increasing speed once again proved that this woman was not an ordinary person. However, she was just unusual. Such a speed was not enough to shake off Shinji and the others. On the contrary, Shinji hoped that she could run faster. The sooner she returned to the hiding place, the sooner they could finish their work.
This time the woman did not disappoint them and really returned to her old nest, an apartment building just two blocks away from the Matou family's mansion.
"I didn't expect to be so close... Did the people of Loreleija overlook the darkest part? Or is there something else going on?"
Shinji landed from mid-air while thinking. He first put Fujino in a corner and asked her to watch from outside. Then he and Kirie quietly went up to the balcony of the woman's residence.
A moment before landing, Shinji felt his feet go numb, as if he was being shocked by a weak electric current. This was a spontaneous reaction of his own magic circuits sensing the alien magic power.
"Barrier?" Shinji was not surprised but happy.
The presence of the barrier meant that he had not made a mistake, and also meant that Wuhui's analysis was correct. There was indeed someone else behind this strange woman, and their skills were not low. In the past few years, he had already read most of the barrier techniques left by Araya, and was considered a half-barrier master. He could feel the presence of the barrier after landing, which was impossible without a certain level of skill.
According to the nature of the magic power emitted by the barrier, the function of the barrier is to detect living things, which is very effective for living things, but not for non-living things. Shinji immediately changed his plan after realizing this, and separated a wisp of his spirit to rely on Kirie's "dual existence" to explore inside, while he returned to meet Fujino.
When he landed next to Fujino, he "heard" two unfamiliar voices—
"You're back?"
"Um.
PS: The so-called darkest place under the lamp is the shadow under the light, which is right under our eyelids but is easily overlooked.
PS2: The scoundrels in the Shogi Association are not referring to Mr. Bayi, but the real Shogi Association. The book "The Ryuo's Work is Never Done" has been strongly supported and promoted by the Shogi Association. Although the original novel's description of Shogi is very good and exciting, there are also many loli plots in it. From this point of view, it is clear what kind of character the Shogi Association that is vigorously promoting is - the restoration of Mr. Bayi in the animation is not very good, so read the novel if you are interested.
