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

"I wonder where that paper airplane ended up, and those envelopes never even reached you..."

Karen sighed silently, a tear sliding down her cheek and onto the ground.

She reached up and wiped away the tears on her cheeks, a feeling she couldn't quite describe welling up inside her.

Moved by the music and hearing the story about her, she couldn't help but shed tears.

But she no longer had any doubts about this story of her comrade-in-arms, and her previous dreams and the more distant past gradually became clearer.

...

The wind travels through still time.

The man's consciousness had faded, but his last words still echoed in the still wind.

"...That's the story."

"I went to the far future, experienced all sorts of adventures, and finally had the opportunity to tell you the truth about the world like this."

"Don't worry. This time, everything will change because of you."

"Just like a long, long time ago, you changed a certain boy."

It was a spring morning…

"He, who was disliked by others, met you, who had climbed over the wall to come to him."

"You greet him warmly and invite him to play with you."

"This boy found redemption in his life."

"..."

"........."

Then, a pair of blue eyes slowly opened, a hint of hesitation and complexity on her pretty face. From those tear-filled eyes, one could vaguely recall the time she looked down at Otto from the wall.

After that, she found the person she would rely on for the rest of her life.

Just like that boy who always supported her.

This is the most selfish thing a person can do.

...Yes, it is the greatest thing a person can do.

Chapter 212 The Golden Courtyard... collapsed

With Otto's story finally settled, everyone has gained a deeper understanding of him.

This long journey came to an end as he reached the final destination of his life.

When a person dies, it's like a lamp going out.

Even the most intense emotions of the past are now suppressed and replaced by calm at this moment.

How long, how magnificent, how indescribable must a 500-year lifespan be?

Otto Apocalypse, this man, his 500-year life can be summarized in just two words—"Karen".

Ah, how long it has been.

Ah, how fleeting.

Those seemingly endless years have passed in a fleeting glance and are already nearing their end. Looking back, I have found my original self again.

Only the final words remained—

"That's the story. I went to the far future."

"Karen, live on!"

The scenes still echo in my ears. He left behind not only memories in this world, but also a deeply moving emotion.

This also made everyone realize... how important the name Kallen was, almost to the point of permeating the entire life of this most distinguished person in the world.

Even after a long time, the image of the greatsword consumed by heavenly fire and the figure falling from her dream still stirred Kallen's heart.

Otto's story has finally come to an end.

She also learned what the other party had done to make the world seal all of this away and obscure history with smoke and dust.

Her tears continued to flow uncontrollably, drop by drop.

The pain in her heart had subsided, but the feeling of blockage still pounded against her mind in waves.

She felt countless words were about to spill out, but in the end, she held them back.
