To create Honkai Impact 3rd in a world where Kallen exists.

"but now……"

As she approached the turning point, she pursed her lips, looked at the other person, and felt a pang of reluctance.

"Klein... in your eyes, am I someone who will never change?"

Mebius sneered.

She never considered the betrayal of her only confidant. So... was that person still her confidant?

Klein continued speaking, each sentence striking at her very soul.

"But what you did today... is definitely not the choice Mebius would make."

"Doctor...like other humans, no matter what changes she has undergone, she will always retain some unchanging parts."

"And that is precisely the difference between you and her..."

"The difference between her and me...? Are you kidding me..."

Mebius would not admit this.

She is the real Möbius, and there is no difference between them!

The conversation between the two continued, and Klein took out something...

This completely shattered all of Mebius's ideas; it was irrefutable evidence.

"I know I can't convince you."

"Wha...what?"

“She left some things and asked me to give them to you. But I haven’t done so.”

"In my opinion, passing on Mebius's information to Mebius... makes no sense."

"Until now."

Klein raised her hand and took out something she had been keeping hidden in her bosom.

That was just a video, a video that contained the real words of Möbius.

"Leave something behind... for myself? Are you trying to pull some trick on me, Klein?"

"I'm not that sentimental. This kind of meaningless formalism doesn't seem like it at all..."

The Mebius on the ground still didn't believe what the other person said; she couldn't believe that another version of herself would do such a futile effort.

She sneered, clenching her fists, and looked in Klein's direction.

But at that moment, a voice familiar to both of them suddenly rang out in the space, perfectly matching Möbius's words from before. It was a voice they both knew—Möbius's own voice.

“I know this isn’t something I would do, but if there’s anything I need to tell you,”

"This is the last chance."

Between Möbius and Klein, a tall, voluptuous figure appeared, wearing a white lab coat and intellectual-looking glasses.

She had the same long, green, curly hair as the girl on the ground.

The other person was the same person, with the same voice and the same appearance...

What? Möbius's memory isn't Möbius...?

So, who is Mebius? (laughs)

[The difference? It's obvious! Height, bust size, weight... the difference between you two is very clear!]

"Hmm... how should I address you? Or... Möbius? The other me?"

She greeted herself, who was now living in another era, and there was none of the image that should have appeared.

At least in terms of real-time performance, it appears to be completely synchronized.

I ignored the other person because I knew that nothing they would do would make a difference.

The other party is just sending an audio message, and there won't even be any response.

Mebius merely narrowed his eyes and glanced at the even more petite girl over there. Was this the reason for her 'betrayal'?

He spoke in an indescribable tone.

"What, Klein? You prefer me back then, don't you?"

"This holographic image is what the doctor entrusted me to pass on to you."

Klein said with a hint of sadness, even though she might have forgotten what sadness was.

"She recorded this... just before she was about to die."

“Death? Klein, do you know what you're saying? For me, death is simply impossible….”

Mebius on the ground argued,

But what she said wasn't entirely wrong. Yes, the idea that Möbius was immortal was almost universally accepted in that era.

Everyone believed that even when civilization was on the verge of destruction and extinction, Möbius would not be forgotten by time.

"Yes, I can't believe it either, that I'm really going to die."
