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

"It told me... that only death is eternal."

"You must understand, right?"

"I would never have imagined that the phrase 'on my deathbed' would one day be used to describe myself."

"Of course, if I want to... even the Herrscher of the End might not be able to completely kill me."

"That's not very convincing, is it? He's clearly already in this near-death state..."

“But you are another version of me, so I don’t need to explain to you… that I wasn’t lying.”

"Even if civilization is destroyed and the earth beneath my feet ceases to exist... as long as the end of time has not been reached, I still have the possibility of being resurrected."

She uttered some arrogant words, but the people present did not hesitate at all, completely believing her claims.

Simply because... she is Mebius!

This is enough.

"But now... I'm not willing to do that anymore."

"For Mebius, this death is the last."

"..."

She finally stopped talking and remained silent for a long while.

"What, finally realizing you've been spouting nonsense?"

Möbius raised his face, but there was no trace of empathy or sadness on it.

His eyes held only pity and mockery as he looked at Möbius, who was speaking eloquently before him, repeatedly referring to another...

She shouldn't be so ignorant of... 'herself', right?

"Really... how did I suddenly start talking about these things?"

"Is it because I finally feel that I am about to die? But this is clearly the message I wanted to leave you... Möbius."

"Before my eyes, infinite possibilities are converging toward a predetermined end."

"The coming of the end will soon turn everything in this generation into a wasteland of ignorance..."

"Although I don't care, I still feel... I should convey these words to you before that."

"Whether it's Grey Serpent or Klein, they've both heard these words, and I believe... they'll definitely understand my intentions."

"But... I'm a little worried about the other me."

“…” Mebius simply narrowed his eyes, without making any comment.

What exactly is the other person saying? What worries, fears, terrors...?

Are snakes supposed to be cold-blooded creatures?

No?

So why is it so strange? And what about herself... She felt inexplicably irritated.

"You and I face different situations; an infinite road still stretches out before you into the distance..."

"No one can interfere with you, and no one has the right to make choices for you... not even me—your creator."

"……enough."

She stopped him again.

But just like last time... it had no effect.

Whether the other party ignored it or was caught off guard, it revealed their thoughts.

She doesn't care about any of her actions.

"Of course, you are still Mebius after all."

"If in the end you still walk the path that belongs to Möbius, and still choose to become me..."

"That is also...the choice you make based on your own will amidst infinite possibilities."

"You are free no matter what."

Yes, she is free...

Mebius on the ground merely smiled mockingly, looking down at the ground and the blurry, indistinct reflection.

But that was before you came into the picture...

Why...did you appear?

Klein's voice appeared in the recording: "Doctor, the hibernation pod is about to activate. Please come over here quickly."

"Okay... I'll be right there."

"It seems... that it's not entirely true to say that I failed completely."

She said with some relief, referring not to complete failure, but undoubtedly to Klein's voice from before.

“Infinite possibilities… I can no longer possess them after I discovered my error.”
