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

Kiana couldn't help but exclaim in surprise.

Although I've always been curious about Durandal's appearance after her return—the tuft of white hair on her head, and the new power she's gained—

Sometimes, the way he looked at her was filled with complicated emotions...

All of this inevitably made her overthink things.

But to think about it that way... judging from her expression now, she clearly hasn't considered it at all. What to do when suddenly you have an older sister, who's also your comrade-in-arms?

Kiana's hand clenched and unclenched repeatedly, her palms becoming slightly sweaty.

"Uh... Durandal... no, Kiana... um..."

In an instant, this invincible Herrscher of Fire stammered and was defeated by a simple title.

“Uh… Kiana, just call me by my original name. The name Kiana already belongs to you… As for Siegfried… the mistakes Dad made…”

Durandal couldn't help but facepalm; she was also troubled by this kind of troubling matter.

"I'll explain it to him personally when the time comes!"

Why insist on using the same name? If it weren't for his amnesia later on, he would have actually come to accept the name Durandal instead...

"Okay, Sister Durandal! Ah, you just mentioned... Dad?"

Kiana's eyes lit up.

She had searched the world for Siegfried, whom the other party had mentioned, many times, but had never found any information about him.

As for the older sister in front of her, although the aunt was surprised, she earnestly took the other's hand.

This undoubtedly also indicates the possibility of his identity.

Besides... even the strongest Valkyrie wouldn't need to impersonate this identity.

"Hehe—surprised? To be honest, I was shocked for a long time!"

The Herald of Knowledge nodded, satisfied with the shocked expressions on the faces of those present. It hadn't been in vain that she'd thrown out such a sensational topic right from the start to grab everyone's attention.

Then, feigning mystery, she asked another question.

"However, what's even more shocking is what happened to you in the other world. Tsk tsk, you really did become good sisters. And guess what, there's someone else who's also your sister. Who is it?"

"There's another sister?"

Kiana blinked, then calmly shook her head, indicating that she knew nothing about it.

Could it be that Dad has some illegitimate daughter?

No wonder, we haven't been able to find him no matter how hard we've tried these past few years.

"Could it be Bronya? It would be quite interesting if she became my sister."

Kiana said with a mischievous smile.

Having defeated a formidable foe, she relaxed her vigilance, as did the burden that had always been on her shoulders.

With Xiaoshi's guidance these past few days, she has regained some of her former liveliness.

"Heh, how could that be? Bronya grew up in an orphanage," Bronya coldly shook her head in denial.

Bronya thinks Sirin is a possibility, after all, in some ways, she is the one who is most entangled with you.

"How could this be, Sirin..."

"You guessed it, it's Celine."

The Herrscher of Knowledge snapped her fingers and nodded to Bronya with some approval.

Although the opponent suffered repeated defeats on the battlefield, he was quite quick-witted in life, truly worthy of being called the Herald of Reason!

"Huh? Sirin! How could this be—"

Kiana looked somewhat bewildered. She understood everyone else, but as for Sirin... how could she become her sister?

Moreover, it seems I was born from Sirin...

"Hmm... I don't know the specifics, but Cecilia from that world is alive, and Sirin should eventually be connected to her?"

The Lawbringer looked up at the ceiling and then gave his answer.

Although she hadn't paid much attention, she could guess what it was about by thinking about it for a moment and combining it with the memories of the old antique.

“Cirin… is also a sister, and so is our mother. I’ve never met her before.”

Kiana's eyes showed a hint of disappointment.

"Cecilia! Hmm, so much time has passed since then? I miss her!"

Theresa heard a familiar name from her memory, and a light flashed in her eyes. She looked at the Herrscher of Knowledge with eager anticipation and said with some excitement.

"Quickly, tell us more about her!"

"I'm also a little concerned about it."

Durandal smoothed her hair and said nonchalantly.

But the fact that she was able to speak at all showed her attitude.
