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

A magnificent warship slowly docked in the weathered town, its vintage atmosphere emanating from every corner.

He arrived at... the stage he had prepared for five hundred years.

They were greeted by the Valkyrie Durandal.

After a brief exchange of pleasantries, Durandal frankly told the other party that she was also unaware of the bishop's plans and could not contact him.

If it were anyone else, Theresa and the others wouldn't believe what they said.

But if this person were Durandal... they would trust her more; if she said she didn't know, she really meant it.

As the person in charge here, she gave the other party a brief introduction to the situation, including the anomaly of the spacetime projection.

Einstein and Tesla were visibly shocked; they had also conducted similar theoretical research.

The spatiotemporal information of a certain historical period in the past is projected into the current spatiotemporal space... How much energy would this require to support it?

Their calculations at the time were... that current human technology could not achieve this; only the power of Honkai could.

This is not a natural landscape that can appear in reality; it generally only appears on one side of the Imaginary Tree.

In other words... it can also be considered an imaginary invasion phenomenon, and the singularity is naturally the core of the Herrscher of Dominion. If it is not handled properly, a Honkai attack is very likely.

In response to this phenomenon, Theresa had to admit that they needed to get involved in solving the core issues.

But this time she didn't want her students to be in danger, so she and Durandal went to investigate.

For some reason, with just a few words from Einstein, they successfully lured Dr. Tesla into joining the exploration team. It must be said, they truly are old friends who have known each other for many years.

This sense of proportion... was perfectly controlled by Einstein.

Tesla successfully agreed to go there voluntarily simply by leaving the excuse that he needed to speak with Otto. Congratulations!

...

In this quaint town, ancient trees stand side by side, moss covers the broken stone slabs, and the antique buildings exude an atmosphere of history.

Especially when combined with those projections from five hundred years ago, the echoing voices of our ancestors, the enigmatic will-o'-the-wisps, and the projections across time and space,

It's difficult to tell whether it's five hundred years ago or now.

In the heart of Klossen, near the Purple Iris Plaza, they followed the clues of Honkai energy intensity step by step, arriving here.

Upon arrival, nothing particularly unusual happened, until... they heard cries for help coming from somewhere in the corner.

"Vera—"

"—Damn it, what are these?"

The man's voice was anxious, but he was powerless to help.

The group followed the sound and, after dealing with a large number of Honkai Beasts, emerged from behind the broken wall, where layers of dust were being shaken off.

The figure coughed a few times, covering its face, but remained steadfast against the wall, unwilling to waste a single second.

Here, they met someone they had never imagined.

This...this is...their eyes widened.

Looking at the blond, blue-eyed man emerging from the dust, dressed in the robes of a Destiny Bishop, his face gradually matching the one in my memory, it was... hard to believe.

Although I don't know what happened, the person in front of me is definitely Otto.

For a moment, the group looked at each other, dumbfounded.

No one could have imagined that Otto would run into him here.

"Ah, thank goodness, we've finally encountered some living people! Have you seen a girl?"

"She had silver-gray curly hair, tied in a single ponytail, and wore a beret. She was probably about a head shorter than me..."

The blond man's face lit up with surprise and delight, and he hurriedly asked.

Otto? What's he up to now?

[That description... doesn't seem to be Kallen? Vera... who's that?]

【Klosten...how meticulous, it seems to be the name of a town from a history textbook from five hundred years ago】

[Just a Tesla, and they were easily fooled... What a disaster!]

"Uh... why is he here?"

Even Theresa, who was watching from outside the video, was puzzled. She had been following the plot closely.

She had already planned for Otto to appear in the ending, stab her, and then watch her granddaughter's corpse fall, her face expressionless, without joy or sorrow.

Although it was just a fantasy, and she knew it was impossible, the scene still involuntarily appeared in her mind because of the lesson she learned from the knife incident.

Or perhaps... she finally picked up Judah's chain and passed it through Otto's body, green liquid gushing out from it. With her eyes closed, she cried out—Goodbye, my grandfather, and my cowardice.

Thinking about things like that actually feels kind of exciting. Sure enough, she might have been influenced or led astray by someone.

Theresa shook her head, banishing those pointless fantasies.

"Aren't you a voice actor? You didn't know?"

Alicia turned her gaze over and asked in confusion.
