Let the Bizarre Adventure of the Joestars begin.

“Ha, do you even need to ask such a simple question? Of course, it’s because we don’t understand Otto. To deal with someone you don’t understand, you have to have power that is much stronger than his.” Miss Jeanne picked up the Herrscher Core that was placed on the table again and said, “And if you don’t want to be killed by him, you can only go back to the past and take a look. After all, it’s very difficult to do without first-hand information.”

"So that's the reason? It seems your credibility as Sherlock Holmes has increased considerably." With a snap, Einstein slammed the book shut, a slight smile playing on his lips. This time, however, he didn't stick out his tongue. "But..."

"However?" Miss Jeanne listened to Einstein's words with a hint of doubt, but still repeated them cooperatively, trying to find out what Einstein was trying to express.

“I’m going too.” After saying this, Einstein stuck out his tongue: “After all, as you said, if it’s not firsthand information, no one knows how it will be altered by others, right? Besides, paper documents and other documents are bound to have problems. After all, this is a journey through worlds, and no one knows what will happen. So, it’s better if I go and see for myself.”

"He actually used my words to refute me..." Looking at Einstein sticking out his tongue, Miss Jeanne couldn't help but laugh.

However, after laughing, Miss Jeanne added, "I have no idea how many worlds I'll have to go through to get to where I want to go. If you have the patience, just keep following me."

"The allure of other worlds is immense for scientists." Listening to Ms. Jeanne's words, Einstein's meaning was quite clear, so clear that the answer could be found without even thinking about it.

“But according to your statement, then there will be three people going this time.” Looking at Einstein, Miss Jeanne turned around and walked towards another place, seemingly to make some preparations for what was to come. Watching Miss Jeanne’s departing figure, Einstein naturally knew what she was going to prepare.

Previously, it seemed that Miss Jeanne's time travel didn't require any preparation, but this time it's different. This time, in addition to time travel, she needs to prepare a few other things. After all, Miss Jeanne's prediction is that if she really goes to the place she envisions, there is a high probability that she will encounter a battle as soon as she steps out. But there's nothing that can be done about it, since that's just how things are in that place.

"May I ask who the other person is?" Einstein asked, opening his book again as he watched Jeanne's retreating figure.

"Is that even a question? Of course it's Cecilia." Hearing Einstein's question, Miss Jeanne turned her head back, letting Einstein see her profile: "Since I promised Cecilia, I can't leave her alone in the future."

"Is that the reason? It seems you and Cecilia are important to each other." Einstein said this upon hearing this.

"Isn't what you're saying obvious?"

After thinking about it, I tore up the draft (laughs).

We cannot ignore tomorrow's planet (Part 1): The prologue is the same yet different.

It was cold, and something was licking her face. This sensation woke Miss Na from her coma.

Opening her eyes, she saw huge snowflakes and heard the sound of heels hitting the ground. Judging from the sound, Miss Jeanne could tell that the person who approached her was wearing high heels, but not too high. After all, there aren't many girls in high heels who can run that fast.

As the sound of heels tapping on the ground grew closer, a shadow finally blocked Miss Jeanne's view. Looking in the opposite direction of the light, Miss Jeanne saw a girl with purple hair, and unfortunately, Miss Jeanne knew this girl.

Mash Kyrielight, the only Demi-Servant I've ever seen who appears in a state of fusion with or possession of a Servant, but at this moment, Jeanne is quite certain that what she's seeing is a human, not a Demi-Servant.

As for why Jeanne is here, the reason is that this time, Jeanne's journey through time has encountered the same situation as Cecilia's arrival in the Joestar world. However, this time is different. Jeanne is already familiar with how to use the Herrscher Core, so she is protecting them. But anything can happen unexpectedly. Once again, Jeanne, in a situation she doesn't know how to describe, successfully separated from them. And a second before they separated, Jeanne gave Cecilia the Herrscher Core and the Lesser Grail that split off from the Greater Grail, so that she could take Einstein with her.

"Who are you?" Miss Jeanne could tell that this Mash was not the Mash she knew. After all, the Mash she knew had long since become a Demi-Servant, while this Mash was clearly still in a human state.

"Well, should I say I'm just a nobody... or something like that?" Mashu coughed and introduced herself in that way, though no one in the world would introduce themselves like that.

"A nobody? No, you're not a nobody at all. At least, you're very pure in my eyes." Jeanne said this as she looked at the girl who was having a headache because of the self-introduction. However, Jeanne's words sounded more like an affirmation of Mashu than a joke.

"Well, it's just that I don't have many opportunities to say my self-introduction or leave a lasting impression, so that's why I said that." Hearing Jeanne's words, Mashu's face suddenly turned red. After all, anyone would feel embarrassed to be said that by someone they had just met. But in the end, Mashu realized that Jeanne never said anything without a basis.

And what Ms. Jeanne is saying now will ultimately be just like what Mashu said back then.

"So, what's your name?" Seeing Mash suddenly blush, Jeanne smiled and asked her. Although she already knew Mash's name, Jeanne felt it would be better to ask.

“My name? My name is Mash Kyrielight.” Mash answered instinctively when she heard Miss Jeanne’s question.

"Mash, okay, I'll remember that name." The final result of asking for the name was just as Ms. Jeanne had guessed. Even in different worlds, Mash's name remained unchanged. Thinking about it from this point of view, Ms. Jeanne came up with even more random possibilities. However, since the person who could really solve these problems was not around, Ms. Jeanne could only obediently record her guesses for now.

"By the way, Mashu, I wanted to ask, is there someone here named Fujimaru Ritsuka?" Although Ms. Naruto had obtained a lot of information from Mashu's answer, it wasn't enough. That's why Ms. Naruto asked a new question.

Of course, Ms. Jeanne raised the question with Mashu's personality in mind, since Mashu is indeed not very good at lying.

"Fujimaru Ritsuka, huh? I don't recall anyone with that name." Mash answered Jeanne's question after a moment's thought, but the fact that she thought for so short a time made it hard to believe she had given it any real thought.

However, Jeanne knew that Mash's answer meant that Mash had really thought it through, but this answer only made Jeanne think about it again.

So, what does it really mean that Fujimaru Ritsuka is not here?

"What is that?" However, the current situation is that no matter how much Miss Na analyzes, it's useless. After all, as mentioned before, the person who can truly draw a conclusion is not here. So, no matter how much Miss Na thinks, it's pointless. Moreover, since the Herrscher Gem is not here, Miss Na can only obediently wait for them to come looking for her. However, with the Lesser Grail and Einstein's words, Miss Na feels that it shouldn't take them long to locate her and come looking for her.

"That squirrel-like animal is Fou." Mash, completely unaware of Jeanne's tactic of changing the subject, fell for it so easily. However, considering that not many people usually use this tactic on her, perhaps it's normal that she fell for it.

As Mash teased Fou with her finger while answering her question, Jeanne replied, "It's a creature with privileges that allow it to roam freely in Chaldea."

Not long after Mashu finished speaking, Fou jumped onto Jeanne, spun around on her a couple of times, and then ran away.

“Like taking a aimless stroll.” Mashu added a sentence to supplement her previous explanation as she watched Fou walk away.

"What an interesting creature." Miss Jeanne sighed as she watched Fou run away. After all, Miss Jeanne had traveled to so many worlds and had never encountered such a peculiar creature.

“It doesn’t like to get close to anyone but me, but it seems to really like you, senpai.” Mashu said this as she reached out her hand to Jeanne, trying to help her up.

As for Mash's outstretched hand, Jeanne naturally reached out and grasped Mash's hand, then used her other hand to slightly lift herself from a sitting position to a standing position.

After helping Jeanne up, Mashu added, "Congratulations, the second owner of Fou in Chaldea is about to be born."

I switched volumes so suddenly, but I went back after finishing the prologue. Don't worry, after all, Chaldea does have some technology related to time travel.

We cannot ignore tomorrow's Earth (Part 1): Chapter One So, there's only one answer! (Broken)

Chaldea is an institute and observatory that brings together researchers from all fields, including magic and science, to ensure the long and resilient continuation of human history.

Mashu introduced Chaldea in this way, a description that Naruto had already heard before. However, hearing it again now might not be a bad thing, since Naruto could hardly remember much of what had happened back then.

"And the main research here is developing Earth's environmental model, Chaldea." Although Miss Jeanne had heard most of the previous introduction, she was completely unclear about the following one. After all, she had roughly guessed the previous part based on what she had seen of their actions when she was in another Chaldea. However, the following part was something she hadn't heard at all. Although she could roughly guess what it was, Miss Jeanne thought it would be better to listen to it anyway.

"Chaldea?" she asked, feigning a question, but Jeanne's actions were merely a ploy to extract information from Mash so she could better understand the situation.

“They define planets as having souls, and Chaldea is a miniature Earth created by replicating the soul of a planet. Generally speaking, as long as there is still the light of civilization on Chaldea, humanity has a future a hundred years from now, but…” Mashu hesitated a little, as if considering whether to tell Jeanne about these things.

"But these lights have recently started to disappear without warning, haven't they?" Miss Jeanne speculated, recalling the Chaldea she had seen in another Chaldea that had almost completely lost its light, the one commonly known as the giant globe.

"Eh, how do you know, senior? Aren't all the people who come here unaware of this situation?" Mashu seemed quite surprised by Jeanne's words, but that made sense; most people wouldn't say something like that so directly.

“Of course, it’s all about proper reasoning. You see, when an organization suddenly starts recruiting people without warning, it usually means either there’s a personnel crisis or a major layoff. But the people you’re recruiting are all highly representative, meaning they have to go through a lot of testing to be selected. That means they have to attract a large number of talents because of a new project. And then, considering what you said about the spark of civilization, Mashu, and this kind of recruitment, we can basically draw a conclusion.” As she said this, Ms. Jeanne raised her hand slightly and placed it on Mashu’s head, gently rubbing it.

"Eh? Senior, that's amazing."

"No, it's just basic common sense." Feeling Mash's soft hair, Ms. Jeanne said, "Then, what does such a large-scale disappearance of fire mean? Please explain that, Mash. After all, that's all I can speculate about."

“According to our observations, human history will be completely wiped out in December 2016. After compiling a large amount of information, we have finally observed a new anomaly, namely Singularity F.” After listening to Ms. Jeanne’s question, Mash summarized the information she knew in Chaldea for Ms. Jeanne: “Also, could you please stop patting my head, senpai?”

"Ah, sorry, sorry, it was just a slip of the tongue." Sensing something amiss with the latter part of her statement, Jeanne quickly withdrew her hand. If Jeanne were to look down at Mash's face at that moment, she would see Mash's face flushed red: "So, what's the deal with this so-called Singularity F?"

"Singularity F, which is in 2004 AD, occurred in a city in Japan where a history that did not exist up to 2015 appeared—a so-called unobservable area. Chaldea hypothesized it as the cause of human extinction and proposed a spirit particle transfer experiment to the United Nations, which was approved." Listening to Mash's explanation, Jeanne finally obtained the information she wanted: the so-called spirit particle transfer system. The data Jeanne had obtained was data from that system; without it, Jeanne would have been unexpectedly troubled.

"Spiritual particle transfer?" After several previous attempts to probe, Miss Jeanne asked seemingly casually, but she knew that Mashu would answer, just as she had answered her doubts before.

For some reason, when Jeanne looked at the pure Mashu, she felt a pang of guilt. After all, anyone would feel guilty if they kept deceiving the innocent Mashu like this.

"Spiritification is the act of sending a human spirit to the past to intervene in phenomena. In layman's terms, it's time travel. By using this method, you can travel to the past, find out the reason for the disappearance of the future, and then destroy it." Then, as expected, Mashu was tricked into revealing information by Jeanne. Moreover, Jeanne also obtained some unexpectedly interesting information from this time's probing. However, rather than information, it was more like she realized that she hadn't come to the wrong place this time.

"I see. However, I don't think things are that simple." Having obtained the information she wanted, Miss Jeanne only had one thing left to do: break her hand... no, wait for Cecilia and the others to arrive. After all, if it were just data, Miss Jeanne could take it freely, but there was only one person who could see the data, so Miss Jeanne could only obediently wait for them to arrive.

"So, you're going to rewrite human history? What a grand plan! But I don't think things will be that simple," Miss Jeanne said, stroking her flawless chin with one hand.

"Eh, why do you think that, senpai?" Mashu sensed that her senpai was not simple, given Jeanne's speculation.

"The reason? Well~ it's hard to say, but what I can say for sure is that this so-called Singularity F might be so difficult that it could wipe out all of us who passed the test." Jeanne said this in response to Mash's question. But it's understandable, after all, you can't exactly say that you came from the future and saw all your Masters die.

However, in any case, at least Miss Jeanne now knows what she should do, which is to wait and hold onto hope... no, to wait for Einstein to come. And, if possible, she should also help Mashu get rid of this so-called Singularity F. After all, it would be quite heartbreaking to see such a pure girl all alone and helpless.

We cannot ignore tomorrow's Earth (Part 1): Chapter Two Jeanne: Doesn't wearing a green hat weigh you down?

Mash Kyrielight, a member of the human resources agency Chaldea. When Jeanne met Mash, she was already a Demi-Servant. Before being stabbed in the back by that bastard, Jeanne still had information about Mash.

However, after being stabbed in the back by that bastard, all Miss Jeanne could remember was her time in Chaldea. As for her memories before that, she had no recollection whatsoever. Although she could initially find some fragmented memories, now she had absolutely no recollection of that period.

"By the way, Mash, you don't know my name yet, do you?" Jeanne smiled as she looked at Mash, who hadn't yet become a Demi-Servant. Although her memories of Chaldea weren't exactly pleasant, Jeanne still had a good feeling about Mash. After all, a girl like that wouldn't be unpopular, right?

Moreover, Mashu wasn't entirely oblivious at that time; although it was just a short sentence, and Jeanne didn't understand it, those words did make Jeanne realize something. Although the words were too subtle for Jeanne to understand at all, Jeanne's words at that time were quite normal. After all, compared to herself now, that little Jeanne was just a naive and innocent girl.

However, in any case, Jeanne's impression of Mash wasn't too bad, which is why she was able to sit here and talk to Mash so comfortably.

Similarly, this world also lacks the Servants and Masters who killed her, so at least for now, Ms. Jeanne's impression of Chaldea is still quite good.

"So, what is your name, senior?" Mashu asked cooperatively upon hearing Jeanne's sudden question. However, in reality, wanting to know Jeanne's name might also be a thought hidden deep in Mashu's heart.

“My name is Jeanne Joestar, and I’m a detective who isn’t very famous.” Jeanne answered casually in response to Mashu’s cooperation. However, even if Mashu hadn’t asked, Jeanne would have told Mashu her name anyway: “Mash, how long have you been here? You seem to have never been in contact with the outside world.”

"I... I've been here for two years now." Mashu was a little confused by Jeanne's self-introduction, but she still answered Jeanne's questions properly.

"If it's two years, shouldn't you be the senior?" After hearing Mash mention her time at Chaldea, Jeanne asked, "Then why do you call others 'senpai', Mash?"

“To me, everyone in Chaldea is a senior.” Mash explained to Jeanne’s question in this way, but if that was all there was to it, Jeanne wouldn’t be able to get any more information. However, Jeanne did feel that she no longer needed to spend time getting information from Mash.

As for the reason, it must be the sound of footsteps approaching from afar; just like Mashu's case, it was the sound of heels hitting the ground. As for why Jeanne was so clear about this sound, it was of course because of her experience in London. After all, back then in London, almost everyone wore leather shoes. In addition, given the special nature of Jeanne's profession, it was quite normal for her to be accustomed to this sound.

"Mash Kyrielight, so you're here." As the sound of heels tapping on the ground grew closer, the last green-clad figure appeared around the corner of the corridor.

"Professor Rafe." Mashu naturally greeted the green-clad guy, even though Jeanne thought he didn't look human at all.

However, from a rational perspective, there is no doubt that this guy named Rafe is human. But even so, when Miss Jeanne looks at this guy named Rafe, she always feels that something is wrong. As for the reason why something is wrong, it is probably because this guy wearing a green hat does not feel human to Miss Jeanne. Or rather, Miss Jeanne does not feel any of the human qualities that should be present in him.

Although there are no means to raise suspicion, and this guy named Rafe seems quite friendly, considering the special circumstances of Chaldea, Miss Jeanne has to treat this cuckolded guy as a dangerous individual.

"The pre-appointment meeting for the Master's succession is about to begin. You should hurry to the control room." Leif informed Mash of the situation as he walked towards them. Upon approaching, he noticed Jeanne: "Eh? You are...?"
