This diary entry was actually published a few days after Miyauchi Hikage's clone arrived in Morioh Town.
When Miyauchi Hikage went to Morioh Town, it was the first day of the exam week.
It wasn't until Toyogasaki Academy's midterm exams ended that Miyauchi Hikage sent out this diary entry.
In the previous few days, he basically shared some stories and settings about the Joestar family and Stands with the girls in the diary, occasionally diverging to chat about other superpowers, such as Personas and Nen abilities from Hunter x Hunter.
Of course, he also emphasized introducing Kira Yoshikage, the legendary hand fetishist who was the final BOSS in Part 4 and became a protagonist fusion material in Part 8.
After all, investigating Kira Yoshikage and searching the entire Morioh Town to confirm the number of Stand users in this town was not something that could be completed in one or two days.
It was also because they had been following and staring at Kira Yoshikage for several days without him revealing any flaws, and without giving Kishibe Rohan a chance to be alone with him and release Heaven's Door, that Kishibe Rohan proposed the night raid tactic.
Although the process in the middle was slightly twisted, the final outcome was good.
Although the Mysterious Person had mentioned the existence of aliens in this world a long time ago, he had not talked about anything specific in this regard in detail before this.
As for the girls who possessed the diary, one reason was that they couldn't find the whereabouts of aliens relying on their own power, or rather, after leaving the diary, they might not even be able to distinguish other supernatural ability users around them.
The other reason was that a "Shibuya Incident," which was almost certain to erupt in half a year, was hanging over their heads.
Although they all knew that this incident was related to Ryomen Sukuna, exactly how that King of Curses sealed a thousand years ago would resurrect, what actions he would take after resurrection, and what impact the Shibuya Incident would have on this world were still unknown to them.
They only knew from a few words in the Mysterious Person's diary that after the Shibuya Incident, it should have caused great damage to the Shibuya area.
And after that, the situation in the Inner World should be completely unable to be concealed, announcing to the outside world that supernatural beings had returned to the public eye after two centuries.
In the nearly two months of obtaining the diary, the girls had actually seen the changes in this world.
The trend of spiritual resurgence had long been unsuppressable, and blindly suppressing the supernatural beings in the Inner World was meaningless.
They all knew that in the near future, this world would start a brand new supernatural era. Their views on this point were relatively unified.
The only problem was in what form to enter the supernatural era.
No matter how you look at it, the Shibuya Incident was not a good entry point.
Therefore, Yotsuya Miko and Shinomiya Kaguya had been investigating things related to Ryomen Sukuna in Jujutsu High during this period, wanting to nip everything in the bud.
It was just that their current strength was still a bit too reluctant to contact such a special-grade existence.
After all, Ryomen Sukuna was a powerful existence who could easily create a special-grade Cursed Spirit with just one finger.
Not to mention that Sukuna in his prime could be called the strongest curse user in history.
A Grade 1 supernatural being was not qualified to participate in this matter.
Moreover, the current Jujutsu High didn't think that Ryomen Sukuna, who had been sealed for a thousand years and whose twenty fingers were kept separately, would return to the world.
Before, Shinomiya Kaguya had been trying to make Gojo Satoru more vigilant about this matter.
However, this strongest jujutsu sorcerer in the modern era seemed really unconcerned about these things. Even when she insinuated and asked if Gojo Satoru could defeat Ryomen Sukuna if he returned in his prime state.
Regarding this, Gojo Satoru's answer was still the classic "Nah, I'd win."
Seeing Gojo Satoru in such an overconfident state, Shinomiya Kaguya temporarily gave up starting from Gojo Satoru's side.
Or rather, Gojo Satoru, who had been invincible in the jujutsu world for too long, really wanted to welcome an opponent with whom he could fight heartily for three hundred rounds.
Knowing the news that Ryomen Sukuna might resurrect, maybe he wouldn't even actively stop it, and might even give the other party a chance to recover strength on the side.
Sometimes Shinomiya Kaguya could really understand why the Mysterious Person wrote in the diary that after Gojo Satoru died, his students would complain about this guy instead.
After all, this guy Gojo Satoru was sometimes really too arrogant and annoying.
It was just that none of this mattered now.
The King of Curses from a thousand years ago making a strong comeback after a thousand years of silence?
The Shibuya Incident might lead to the entire Shibuya being burned to the ground?
This was nothing.
Earth, located on the edge of the galaxy, was targeted by so many aliens for some reason. Leaving aside the part that reasonably came to Earth to study Earthlings by normal means, what exactly did the remaining 90% of aliens who specifically smuggled over want to do to Earth?
Then ancient monsters were hidden underground and under the sea. The original Ultraman also ran over to join the fun and sealed a monster on Earth. Who knows when these monsters will awaken along with that Ultraman Tiga.
But the most heavyweight was still that the three princesses of the largest empire in the galaxy would come to Earth in the future, and be conquered by a Japanese gentle male protagonist and become members of his harem.
"So, what kind of messy settings are these?" Shinomiya Kaguya, who had just become a Grade 1 supernatural being recognized by Jujutsu High, was originally quite happy, feeling that she was one step closer to the peak of this world.
But seeing this diary entry updated by the Mysterious Person today, lifting the perspective from the small stage of Japan to the level of stars and seas at once, she really doubted life a little.
However, as a core member of the group, at this time she had to pack up her emotions and take the initiative to appease the uneasy emotions of other girls in the group.
Kaguya: "Anyway, everyone don't worry too much. Didn't the Mysterious Person mention the existence of aliens and people from other worlds a long time ago? Maybe there are even many humans from the future hiding in our era."
"Think about Tohru who was saved by Menma. Isn't she a dragon from another world? According to the Mysterious Person, her father, as one of the strongest in that world, also possesses the power to destroy the world."
"It's just that an existence with such power will definitely not take action so easily."
"And isn't there a Japanese high school student who can successfully conquer the three princesses of that empire? The Mysterious Person said that it's a character in an ecchi harem anime, so there's no need to care too much about the settings inside."
"As the protagonist of the story, even if he is just a useless male protagonist who can only conquer others with gentleness, if he really encounters any threat concerning Earth, he and his harem group won't watch Earth being destroyed, right?"
"It should be said that because of his existence, before his story ends, Earth will definitely not encounter any real crisis."
UMR: "And there is Ultraman Tiga. I choose to believe in the power of Ultraman. Even if something really happens to the Land of Light, the Mysterious Person said before that the power of Ultraman Tiga is sleeping on Earth. When that time really comes, that Ultraman Tiga will definitely awaken too."
Leaving aside other things, although in this world, the Ultraman series only had those few series filmed half a century ago, and after that, the Tsuburaya Company in this world went bankrupt and couldn't rise again.
But the name of Ultraman was still quite inspiring now.
After Umaru mentioned that the power of Ultraman Tiga was sleeping on Earth, or rather somewhere in Japan, the girls in the group really felt much more at ease because of this.
After all, that was Ultraman no matter what.
Aliens, monsters, youkai—these had always been the most common opponents of Ultramen, completely considered professional counterparts.
Kuroneko: "But our world is indeed a bit too terrible, right? Not only are there threats from inside Earth, but there are also so many enemies outside Earth, and even dangers from other worlds."
Kasumi Utako: "After all, according to the Mysterious Person, these are all stories created by Earthlings in his world. Creators in every country are more likely to create stories based on the situation around them. Most creators currently trapped on Earth can only set the story stage on Earth."
"Then the world we live in now is formed by the chaotic kneading of countless such stories. So there are various messy supernatural powers on Earth, the galaxy outside Earth is also a mess, and there are a bunch of workers pulled to other worlds to work. Thinking carefully, the settings are too outrageous, but this world can still run smoothly."
"Sometimes, I wonder if the Mysterious Person from another time and space who knows all our stories really regards this world as a real world. Or rather, does he treat us 'heroines in the stories' as humans, or just as NPCs acting according to the plot stories?"
"If it's the latter, the other party probably treats the whole world as a game world unfolding only for him."
What Kasumigaoka Utaha mentioned made the group silent for a good while again.
After all, the Mysterious Person still hid his identity so far, and had no explicit interaction with anyone.
Judging from the description of the diary, the other party was an office worker who had long been an adult before. The identity of a transmigrator didn't have much impact on him before this, nor did he have much interaction with characters in other stories.
Such a person decided to resign after obtaining the diary one day, and then investigated this world alone.
Besides that, they just knew that the Mysterious Person had a rather nasty personality. His favorite thing to do was to see the breakdown of these girls after seeing their original stories publicly executed in the diary.
For example, Kasumigaoka Utaha and Shinomiya Kaguya, who were tortured by the Mysterious Person for half a month successively.
This guy would even specifically enter Miyauchi Hikage's dream to cause trouble because Miyauchi Hikage broke through the shackles of the original story.
Although he was countered by Miyauchi Hikage who awakened the power of fate in the end, it could also be seen from here that the other party should be a guy with a small heart.
However, occasionally this guy would show kindness to some characters.
For example, Katsura Kotonoha who almost fell into the scumbag trap before, Miyano Shiho who was trapped in the research institute as a hostage with her sister, and Gotoh Hitori as a social phobe.
Even because of the Mysterious Person's unique attitude towards Gotoh Hitori, Shinomiya Kaguya really investigated everyone Gotoh Hitori knew before, until she started suspecting Miyauchi Hikage later and then stopped.
Therefore, seeing Kasumi Utako doubting her own existence, Shinomiya Kaguya also stood up again.
Kaguya: "Don't care about the Mysterious Person's attitude towards us. Since he doesn't intend to appear in front of us or actively contact us, but chooses to hide behind the scenes to observe us, then we just treat him as an untouchable higher-dimensional existence."
"Moreover, I don't think the Mysterious Person treats us as NPCs."
"Haven't you noticed? Compared to the month when he first got the diary, the Mysterious Person's style of action in these few days has become obviously different from before."
After all, the previous Mysterious Person was completely alone no matter what he did or where he went.
If speaking of who the Mysterious Person had actively contacted in the past, it seemed to be only the formerly famous high school detective Kudo Shinichi, now Edogawa Conan who turned into a child after taking the poison developed by Miyano Shiho.
It was just that at that time, the Mysterious Person went to find the other party mostly with the idea of having fun.
Because according to Conan's story, as a work serialized for more than thirty years, and having lived in the home of his childhood sweetheart since becoming smaller, he concealed his true identity from her for thirty years.
The Mysterious Person just couldn't stand this kind of plot, so he intervened directly in this plot, exposing the other party's identity directly.
However, after that, the Mysterious Person basically didn't appear in front of the other party, at most asking Jerry to provide some information about the Winery (Black Organization) to the other party.
But this time, the Mysterious Person's trip to Morioh Town was different.
The other party found Kishibe Rohan as soon as he came up, and also spent several days with him while exploring Morioh Town.
Even if the Mysterious Person used some method to cover his face, his behavior these days would more or less reveal some subconscious habitual behaviors.
Kaguya: "So, connecting with the point that the Mysterious Person wrote in the diary that he also wants the supernatural era to arrive sooner, maybe he is already laying the groundwork for stepping onto the stage in the future."
