Now the girls in the group have become quite accustomed to the concept of world lines.
After all, from the very beginning, the Mysterious Person brought out the novel of Saekano and the manga of Kasumigaoka Utaha's IF route in the diary, and severely tortured Eriri's IF route, which was forced to be canceled due to nobody caring.
It was also from that time that these girls knew that many of their stories had multiple versions in the world before the Mysterious Person transmigrated.
Besides Kasumigaoka Utaha having an IF route here, in the story on Gokou Ruri's side, that siscon Kousaka Kyousuke, whom it was almost impossible for her to meet again, also had multiple different heroine endings in the adapted game.
The Mysterious Person even complained in the diary before that in order to let the siblings Kousaka Kirino and Kousaka Kyousuke reasonably play a wave of incest plot in the game, the setting of one route in the game was specially changed so that the two had no real blood relationship.
However, in comparison, Katsura Kotonoha was obviously a bit unluckier. In her original story, she encountered an indecisive scumbag. Even in those seemingly innocent good endings in the game, because of the bloodline of that humanoid self-propelled gun flowing in the other party and various indulgent acts in other endings, it was really hard to have any sense of trust in him.
It was just that compared to these stories focused around them, the Mysterious Person's description of Fuyuki City seemed much more cruel.
Basically, every route would lead to some disasters.
Like in the main world line, a major fire affecting half the city was bound to happen in Fuyuki City ten years ago.
Ten years later, if not handled well, such an ending might happen again.
At the same time, the Mysterious Person's diary specifically mentioned a world line called Grand Order, indicating that this world line was one of the most important world lines besides the main story.
Then in this world line, the whole world was "Incinerated by Human Order" at the start. Human history and future no longer existed. Only the organization where the protagonist was survived and began to travel to different eras to repair history in order to maintain Human Order.
This setting of saving the world might look quite blood-boiling in movies and games.
But what if this worldview fell on themselves?
When the girls in the group just knew that there were many messy aliens and monsters in this universe, their mood was almost this complicated.
Even though the Mysterious Person later said that there were planetary protection agencies and the suppression of those supernatural forces on Earth, those aliens could only cause trouble sneakily. This couldn't make the girls completely at ease, they could only try to avoid going to places that might be targeted by aliens as much as possible.
After all, in their perspective, the jujutsu world seemed to be just like that. Except for special-grades like Gojo Satoru, it seemed to take a normal Grade 1 sorcerer a long time to destroy a city.
As for others like Shinto and Buddhism, because of the existence of Menma, they could roughly know the strength of these two, which was not quite the same as the oppressive feeling of alien spaceship invasions in movies.
As a result, the Mysterious Person mentioned the magic world in the diary today.
Shinomiya Kaguya had heard a little about the situation in the magic world. After all, abroad, especially in Europe, was considered the base camp of magi, and their status was not much worse than Japanese jujutsu sorcerers and Shinto priests.
Or rather, in the heyday of the magic world, Shinto and jujutsu sorcerers here in Japan couldn't compare with magi at all.
It's just that because of the special mechanism of magi, when they cast magecraft, they first needed a relatively abstract Magic Foundation.
This thing was a concept pre-engraved in the "world" by magi in order to easily use magecraft.
To activate magecraft, one must first make contact with the Magic Foundation already engraved in the world, and then extract magic power from a magic power source. This magic power source could come from the magic power inside oneself, or it could be Ether/Mana in the external air. Finally, the magic power was transferred to the abstract Magic Foundation through Magic Circuits, thereby activating the magic formula.
Although this method looked very troublesome, because the Magic Foundation itself was data engraved on the world, different magecrafts also had different Magic Foundations.
From this aspect, these magi who could leave engravings on the world, and whose goal was even to pursue the Root of the world, indeed studied the essence of the world one layer deeper than jujutsu sorcerers and Shinto priests.
But it was also precisely because of this obsessed goal that during the period of Mystery decline, it caused an unimaginable blow to the magic world.
Mystery declined, magic power in the air dropped to the lowest point, and other supernatural systems could more or less hold on.
But in the magic world, those Magic Foundations engraved on the world could hardly be sensed or even collapsed due to the decline of Mystery, dealing an extremely heavy blow to the magic world at the beginning of the Mystery decline.
Followed by a chaotic period lasting for more than half a century, the originally globally influential magic world completely declined just like this.
Several major forces in the magic world also completely fell silent.
It wasn't until the beginning of this century that the Mystery that had declined for a hundred years recovered again, bringing some vitality to the half-dead magic world.
It's just that the current magic world is still far from returning to the situation back then.
Because the Magic Foundation and magecraft of the magic world also have a characteristic, that is, magecraft needs to remain mysterious.
Magecraft has an upper limit. Every additional user is equivalent to dividing the power of this magecraft.
Although actually a system of magecraft can accommodate tens of thousands of magi using the magecraft under this system without any problem.
But as the number of people who know continues to increase, the power everyone can use naturally can only continue to be constantly divided from it.
After exceeding a limit, the magecraft of this system used will be lower than the normal power exerted, so it is necessary to reduce the number of people who know these magecrafts.
It is this nature that makes it difficult for magi to create new cakes.
At the beginning of the 20th century, the world population was just over 1 billion, supernatural aptitude was one in ten thousand, and the whole world had only more than 100,000 supernatural beings. The magecraft of magi could still guarantee power.
But now the world population is marching towards 9 billion. At the same time, after the spiritual resurgence, the threshold of supernatural aptitude seems to have the intention of dropping. With various supernatural awakenings and competitions for talents among supernatural forces, the number of supernatural beings is expected to exceed one million in a few years.
Under such circumstances, even with spiritual resurgence, the status of the magic world is as awkward as ever. It urgently needs a genius theoretical magus to step forward and carry out drastic reforms on the current magi's Magic Foundations to have a chance for magi to reforge their past glory.
It's just that on the side of the jujutsu world, the answer Shinomiya Kaguya got from Gojo Satoru was "It's very difficult."
Not to mention whether the magic world has such ability.
The jujutsu higher-ups here in the jujutsu world are a bunch of bugs, and the noble forces there in the magic world also have many completely rotten ones. No matter which side, it's not easy to bypass these brainless guys who only know how to stare at their own power to build a new stage.
It's just who could have thought that the magic world was already half-dead like this, yet in the mouth of the Mysterious Person, it could still make such a big commotion.
Sure enough, one still shouldn't underestimate these old-brand supernatural forces.
In comparison, compared to those world lines with frequent disasters, the magical girl world line mentioned by the Mysterious Person at the end could indeed be considered the most harmonious world line.
Although the survival of another parallel world was also involved later.
But at any rate, their world was safe.
"So, isn't it good for everyone to draw some more traditional magical girls? Since that Puella Magi Mado came out, you can hardly see any traditional magical girl anime on the market, all describing magical girls in a dark and cruel direction." Umaru complained like this in the chat group.
"Looking at the Mysterious Person's meaning, including this magical girl world line, it seemed to follow a normal route at the beginning, but suddenly turned into a heavy topic later. It must have also been influenced by this aspect."
"But the concept of the Holy Grail War feels somewhat similar to Personas in some places," Ichinose Chizuru, who just awakened a Persona, said in the group.
What the Holy Grail War summoned were well-known heroes in human history, and the images of Personas also came from those heroes and gods.
Her Hassan of the Hundred Faces, Kisugi Ai's Mata Hari, and Sudou Ayami's Tomoe Gozen were all such existences.
Although essentially incarnations of their inner will, from another aspect, the posture and personality they showed were relatively close to these heroes in history.
And following Ichinose Chizuru's words, Sudou Ayami, who had been peeping in the group, seemed to remember something too.
It seemed that the Mysterious Person mentioned Heroic Spirits or something when explaining the power of Personas to her.
He also said that if there was a chance in the future, the power of Personas might be summoned to reality through certain rituals.
So, did the Mysterious Person refer to this Holy Grail ritual at that time?
Summoning her Persona into reality in the form of a Heroic Spirit?
Thinking of this, Sudou Ayami pondered for a while, and expressed this idea in a speculative way in her own tone.
Sure enough, this idea also gained the approval of many people.
Shinomiya Kaguya: "It looks like it's indeed feasible. After all, the Mysterious Person also said that summoning Heroic Spirits itself depends on compatibility and catalysts. And simply from the perspective of compatibility, since you have already summoned them as your Personas in the Metaverse, then you definitely meet the requirements in terms of compatibility."
Saying this, Shinomiya Kaguya also started asking Hayasaka Ai to pay attention to some things related to catalysts.
With the Mysterious Person's personality, taking a trip to Fuyuki City, although she didn't know what the other party exactly did in Fuyuki City, and the other party didn't mention it in the diary, he definitely brought a lot of things back.
Maybe a brand new Holy Grail War might really be created in Tokyo in the future. She hadn't awakened a Persona yet. It was estimated that unless she could encounter her own Palace in the Metaverse, it would be difficult for her to awaken a Persona.
Under such circumstances, gambling on her own compatibility definitely wouldn't work, so getting some "catalysts" first to make some preparations wouldn't be wrong.
Even without that Holy Grail War, collecting some items used by heroes in history as antiques wouldn't be a problem. The Shinomiya family naturally had such financial resources.
At the same time, Shinomiya Kaguya also took a few more glances at Fuyuki City.
This place involved forces from the magic world. It was indeed not suitable for her to go over, but investigating a bit was still fine.
She had a feeling that in this story the Mysterious Person seemed to value very much, there would always be a girl who would get a diary. Even if not the first batch of diaries, it should be in the second batch.
Perhaps the girls who turned into magical girls, or other female magi. Investigating along this direction would always be somewhat useful.
However, for her now, the survival of aliens and another world was not important.
What she valued most was the Morioh Town trip at the beginning of June.
If she could get a Stand in that place, it would obviously further strengthen her strength.
Now half of the girls in the group had expressed their desire to go to Morioh Town together. It was unknown how many of them could awaken Stands in the Morioh Town trip in June.
Shinomiya Kaguya thought so, and then Miyauchi Hikage's figure appeared in her mind again.
This was also an opportunity.
For them, this trip to Morioh Town was to try their luck and see if they could be chosen.
But for a genius like Miyauchi Hikage, who also possessed power related to fate, if the other party couldn't awaken a Stand, that would be weird.
Similarly, if Miyauchi Hikage finally awakened a Stand with ordinary abilities that had nothing to do with his power of fate at all, that would also be very problematic.
Because according to the Mysterious Person, he already possessed a Stand now. According to his own description of Stands in the diary, a person should only be able to possess one Stand.
And looking at the Mysterious Person comparing his own Stand with Kishibe Rohan's Stand, it could be clearly seen that the Mysterious Person had some envious emotions towards Kishibe Rohan's Stand ability that could casually view others' pasts and rewrite others' will.
At the same time, he himself stated that his Stand ability was average, and because it was a reward from the diary, it would be difficult to complete the evolution of the Stand.
So, as long as she saw what kind of Stand Miyauchi Hikage awakened then, Shinomiya Kaguya felt she would have at least more than half the certainty to confirm whether there was a connection between Miyauchi Hikage and the Mysterious Person.
