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

However, it's certain that the First Divine Key was useless; it didn't even notice the prying eyes from the outside world.

Even so, he dared not throw it in front of Theresa, for fear that his destiny would truly be stolen.

"The Void Treasury? I've heard that the First Divine Key has shattered, leaving only a broken core."

Karen thought for a moment and gave the other party the answer.

"Oh, I see. Well, that's a pleasant surprise. One less potential threat."

Otto was somewhat surprised, but then simply said...

There was absolutely no warmth from the so-called old friend with whom he had spent five hundred years.

If the Void Treasury knew this, it would probably only feel helpless.

"Hehe, do you still remember Yae Sakura that I mentioned?"

Karen's eyes held a hint of amusement, but her eyes were still glistening with tears that hadn't yet dried.

"As far as I know, that lady over there should be Miss Ying from Yingjie."

Otto's expression stiffened, but he still brought up his lifelong rival.

The other person must have wanted to bring it up while Kallen was daydreaming, right? Unfortunately, they still couldn't interrupt!

“There’s no need to be so hostile. She’s gone from this world… Otto, I need to reiterate, I don’t like her.”

Karen sat up straight as she spoke to Otto, her cheeks flushing slightly with annoyance, but she still glared at him fiercely.

"Uh……"

When Otto heard this, a secret joy welled up inside him, and he stared at the other person in disbelief.

"Sigh, let's not talk about this for now."

Karen looked somewhat embarrassed; she didn't want to dwell on the matter any further.

"Then tell me your story, Karen."

Otto didn't say anything, but the joy he received still made his heart tremble. It was worth cursing her so many times; she was indeed gone from this world too!

He was indeed interested in Karen's story.

But more so because his body was extremely weak and he could not continue speaking, and he had not forgotten that there was something even more important for him to complete.

"...If you're willing to listen, but it's definitely too long."

"I'm willing to do whatever you say."

Otto simply shook his head slightly and said softly.

...

Karen recounted her past experiences.

Those peaceful daily routines and trivial worries, the rather similar positions of bishop and the journey to resist Honkai, the addition of those thirteen heroes and the confirmation of the name of St. Freya Herrscher Academy, the magical Honkai Impact 3 game and the mysterious Stigmata,

She talked a lot, but it was all very disorganized;

He listened very carefully and attentively.

He would nod occasionally, frown occasionally, and ask questions occasionally, while Karen simply recounted her past, one event after another.

"Sirin, you've survived until now, and there's Kiana too... What a perfect world."

Otto couldn't help but sigh, thus interrupting her narration.

He sensed that the deadline was approaching, that he would soon be leaving, but he was a little reluctant.

Even though I hadn't heard enough of what the other person had to say, and even though I wanted to see that smile again...

He breathed lightly.

“Phew—, with these kind people by your side, Karen, I’m so happy. I believe you will create a miracle that is no less than mine, but in a different way.”

“The spirit of the saint will unite these things, not my endless scheming.”

"As for Theresa, we should make sure she eats more vegetables and fruits... That cooking magic of love has already worn off, and maybe such magic doesn't even exist in this world..."

“Durandal…she will be an outstanding Valkyrie; and as for Cecilia, I hope she is well…after all, I am not a good person either.”

Otto chuckled self-deprecatingly.

Karen's silence seemed to foreshadow the impending end of their time together, a brief reunion that would soon be cruelly severed.

"I will... Otto, but with the Stigmata, can you survive?"

She looked at him with a glimmer of hope; she wanted him to live, for whatever reason.

"maybe……"

Otto glanced at Karen's back, but had no intention of making a move. He simply looked at her tenderly, standing in the crimson desert.

"Then why..."

Karen gasped in surprise, almost taking a step forward.

“But Karen… time is not something that can be fooled. It has already predetermined the price from the very beginning of the choice. Karen, I am already very happy to see this scene and to see your smile again.”
