My sister keeps saying things that make no sense

Actually, my sister has told me not to talk about her when I'm out. I have no choice, so lately I've been trying not to talk about her in public, but since the characters in Pachiko's daily life are either fictional people, inhabitants of the electronic sea, Kujaku-san (the cat), or my sister, I think it's inevitable that she appears in my articles.

Anyway, this person called my sister only says things that make no sense.

Around June, she started saying things like she wanted to soak in a purple culture medium, so when the company president, who happened to be on a business trip, asked me, "Do you have any funny stories about the Fuji-wara sisters?", I accidentally told him that, and the atmosphere became incredibly awkward. When I told her about it, she made a weird face as if it were my fault for telling him, asking, "Why did you tell him that? It's not funny, is it?", but I think the one who is strange is entirely my sister.
I wish she would start a note account herself and do her own thing under the hashtag "#WhatAreYouTalkingAbout", but she refuses to participate in social media at all. I have no choice, so I, her younger sister, will take responsibility and write it down.

Actually, those drafts that I can't even start writing because the titles are too infuriating are all my sister's fault.

It's infuriating to even explain, so I'll skip that, but recently, this person started saying strange things again.

"Lately, it seems like I've moved to a different world."

Huh? That is my real reaction.

#WhatAreYouTalkingAbout

is what it is.

When I listened carefully, it sounded like a story about a parallel world. It seems the common sense from the place she was in until a little while ago is different, and

"The meanings of words I knew until now, and things like that, are different."

apparently. Moreover,

"But you can't prove that, can you?"

She says, and I'm at a loss.

As in fiction, in such a case, the common sense of the world itself changes, so even if you have memories of the previous world, it's hard to get people to believe you. If it were just a simple isekai reincarnation, it would be obvious to everyone around that you are an outsider, but since a parallel world assumes that the person already existed there, it is certainly troublesome.
By the way, when I asked her what was different, apparently, first of all, Macron's birthday is different. Even if she tells me that, I never knew Macron's birthday to begin with, so there's nothing I can do about it.
In the previous world, Macron was a year older than my sister, but now he's younger, she says.

"Also, Mr. Kakefu was alive, you know."

Mr. Kakefu, whom my mother called 'Mr. Sheet' every time he appeared in the commentary, is someone my sister insists was already dead in her world. Indeed, the other day, when he was sitting in the commentary booth for the Japan Series, she said something rude like, 'Wait, didn't Mr. Kakefu die?' Well, even if she asked me who died then, I, Pachiko, wouldn't know. However, Mr. Kakefu is quite an important figure. Isn't it a big deal if even the life and death of such a person is different?

To the skeptical Pachiko, my sister insists that she has moved to a different world. However, as a younger sister, I decided to take the stance that I, too, moved from the same world as my sister.
If you are a younger sibling, you will understand, but the important thing here is not Macron's birthday or Mr. Kakefu. It doesn't matter which world you are in. The most important thing is that, by no means, should my sister be the only one to have made such a fun parallel world move. I'm always with my sister! I won't be separated! It's not fair if it's just her!

"Why do you always have to tag along for everything?"
"No, that's obvious, we moved together. Pachi and Kuunya and everyone moved together."

At this point, Pachiko changed her strategy.
I must interrogate her more thoroughly. Somewhere in my sister's story, there must be proof that I moved with her!!!
I suddenly got excited.

"By the way, when did you move? Yesterday?"

"It's not like yesterday or this month or anything like that."

Which 'that' is she talking about?

"Do you mean earlier? Summer? Around summer?"

"Ah... I had already moved by summer."

It was more subtly specific than I thought. I tried to remember what happened during the summer, but my brain was malfunctioning from the heat, so I don't really know. In the first place, whether it's the meaning of words or anything else, I, Pachiko, interpret things differently from the common sense of the outside world. It's normal for things to be different from known information, so to speak, it's like living in a parallel world on a daily basis, so there's no way to confirm it.

However, here, my sister started saying that, come to think of it, it was around the beginning of July.
Just at that time, an incident occurred where a slightly crazy woman from an NPO who wanted to capture cats trespassed on our property at nine o'clock at night (at nine o'clock at night!). It was so outrageous that we even called the police, but apparently, she had moved after that.

Oh, I see, Pachiko felt relieved.
This sister of mine, despite always spouting spiritual things, perhaps because she is bad with chronologies, hasn't noticed the important thing. Some of you may have already caught on.

(Eh? No one? There is, right? Say there is! At least one person!)

In the first place, from the beginning of this story, my sister thought she had moved alone, but it was my sister who filled my head with talk about the Great Conjunction and whatnot. It was my sister who said that the era would change due to the movement of the stars.
I am not a fortune teller, and I never want to believe in my own fortune-telling, but for a while now, the colors of change and transformation have been strong.
If we moved, this world itself must have moved as a whole. Whether that was exactly in the problematic July, or whether it was gradually moving and became fixed, and those with memories of the past just happened to notice it at that time, I don't know that much.

Ah, thank goodness, case closed.
I almost let my sister parallel-jump all by herself.
