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

Karen couldn't help but question and scold,

She knew... it wasn't good to start saying imperfect things at the very beginning of their meeting.

But she couldn't suppress the urgency in her heart.

Moreover, if it were him, she would lose those concerns.

"I am saving my world, and I have never lied."

Otto said calmly, his gaze unwavering.

Like a lighthouse in the silent night, illuminating a harbor adrift on a turbulent sea, needing no one's comfort, shining alone until the dawn.

He was the same, never going against his own will based on anyone's approval or disapproval.

"...For example, Immortal Red Iris, I wasn't lying?"

Karen chuckled softly, teasing him slightly.

Her eyes held a provocative glint as she raised her chin, her bright eyes sparkling as always.

It was as if the twilight of five hundred years had receded from her, and the experiences of each day and night had flowed away like water, while the waves of the river of time surged forward.

But at this moment, it is a space-time that transcends the world.

The two of them faced themselves in a way that seemed to reflect their former selves, like the heartfelt moment of their expedition, the pitch-black night by the campfire, the overcoat soaked by the river; the bandit who roamed the night, the doctor who worked tirelessly for the Black Death, the hands that failed to hold each other tightly before the prison.

Like the warm morning sun that first crossed the wall, she was as pure and holy as the most authentic saint in the book.

So warm, so nostalgic.

"Heh—I didn't expect you to know such details, but she is indeed my friend. I know her, and nothing will happen. Besides, I really didn't lie."

Otto winked slyly and looked at the other person with a gentle expression.

It seems that Karen does indeed know a lot about herself, but she never intended to deceive him; at most, she would tell some white lies.

He will tell you everything he knows, no matter what the other party wants to know!

"cut--"

Not far away, the Herald of Knowledge clicked his tongue, which was quite noticeable in this space where no one could move. At this moment, silence spoke louder than words, and the other party simply rolled his eyes.

Both of them, without prior agreement, selectively ignored the sounds around them.

"You're lying... but it's not entirely the truth either."

Kallen shook her head, recalling what the other party had said to Fu Hua.

When faced with the opponent's sophistry, Otto always managed to weave lies with a series of truths, yet no one could find any fault with them.

I'm actually more skilled than before.

Otto neither confirmed nor denied this, simply smiling and glossing over the topic.

Not far away, Theresa made him even more curious: did she also exist in this world?

"I'm also very curious. Does that little Theresa exist in this world? And those thirteen heroes who chased the fire, it seems that many wonderful things happen in this world as well."

Otto spoke in a gentle voice, which he tried his best to maintain, his emerald green eyes flashing over the small figure.

That was the only bond he left in this world besides Kallen.

With the help of those people, she will uphold destiny, in a way that is different from what her grandfather has done.

He trusted the other person, but he also felt a pang of sympathy.

Perhaps he wasn't a good enough grandfather...

That magical power of love in cooking—she doesn't know when the other person realized she no longer possessed it.

"Theresa calls me Grandma, okay? Thank goodness I didn't make her call me Mom, otherwise..."

Karen glanced at him and rolled her eyes at him.

"Ahaha, then it was my fault. Her current form of address is quite appropriate. But, Karen, you see... one person's power is enough to change the world, isn't it?"

"How profound is the meaning of a person's death? What a magnificent closure it is! And the future, which had seemed to stand still, moves forward. Karen, you are changing the world, aren't you?"

Otto chuckled twice as he read the other person's reply.

After a brief silence, amidst the other person's somewhat resentful gaze, he couldn't help but ask a question while staring into their eyes.

"Hmm... Indeed, one person's power is enough to change the world. Back then, I underestimated myself. But if I had a suitable childhood friend, things would have gone much more smoothly."

Karen thought for a moment, then covered her mouth and chuckled softly.

There was a certainty in her words; she had wanted to tell the other person for a long time.

"Ha—, that's really something,"

Otto stood there stunned, then smiled helplessly, but he understood perfectly well the implied word "qualified."

"But alas, you even saw that part? Void Treasury is truly useless."

He waved his hand, feigning a headache, but a slight smile crept onto his lips.

Those embarrassing stories became known to others, and even he felt somewhat ashamed to mention them in front of the people he cared about most.
