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

The weight of a soul is so light, it fades away as light in the darkness unknown to anyone.

Kiana watched her leave silently, perhaps reminiscing, perhaps offering blessings, perhaps mourning…

But regardless, the shadow that had shrouded her heart had dissipated, and even if endless storms still lay ahead, she still dared to move forward.

She had grown to the point where she could face the Herrscher of the Void, whom she once regarded as a nightmare, but the Plague Gem in her hand was now burning hot.

The woman she longed for... made Kiana hesitant to face her at this moment. Her composure, which had remained unshaken even during battle, was now wavering.

Will she be satisfied with her current performance?

Can she see everything, see the traces of her own journey?

Will she feel lonely?

Kiana didn't know, but she had no choice, and what she couldn't possibly give up was this only chance to see her.

A white world enveloped Kiana, her vision filled with only chaotic white light. The surrounding scenery seemed both somewhat unfamiliar and somewhat familiar.

It's St. Freya, the school I haven't been to in a long time.

Kiana knew why she was here.

The moment that figure appeared, Kiana's eyes were glued to it.

Reason reminds Kiana that this is a world created by the core memories.

Despite this, she still longed for another chance to see her.

Even if it's just saying goodbye.

She also enjoyed it.

She ran forward, wanting to see that person's face, that fiery red armor—it was the same person she had seen countless times in her dreams.

"Himeko... teacher..."

She spoke with great difficulty, for the person before her was the one she had longed to see.

Celine said she cursed herself, but that's wrong. She placed all her hopes in herself—beauty, blessings, and even the will to live.

That is the most beautiful blessing in the world, the last and most romantic thing a teacher can do for their students!

...So how could it be a curse?

I thought of countless things to say when we met, but the words just wouldn't come out.

"Did I... appear too suddenly?"

She smiled gently, and said somewhat embarrassedly, that the student she once thought was the most mischievous looked like he was about to cry.

[Not sudden at all, not at all, let it happen a few more times!!]

The dead knife suddenly started attacking me... catching me completely off guard.

[It's Himeko! Himeko-sensei... I never thought Kiana would see Himeko here again. Tears well up in my eyes.]

The flame that leads to tomorrow... until now, the flame that ignites tomorrow... from that time on, the flame has been hers alone.

[Does the Plague Gem still hold Himeko's consciousness? It's a pity... this was a conversation destined to end in farewell.]

Kiana shook her head vigorously and bit her lip hard.

"Himeko-sensei... hasn't changed at all."

"Really? Then I'm quite happy." Himeko smiled and accepted the compliment without hesitation.

"..."

"I'm so glad to see Himeko-sensei again... At least, I can say goodbye to you properly in this way."

Kiana tried her best to keep her tone steady, attempting to force a smile as she spoke.

"Really, I'm sure I'm not the only one who thinks you've changed a lot, right?"

"Yes, that's what everyone says."

All of this started to change after you...

"So, Kiana, you finally defeated the Herrscher of the Void, didn't you?"

“Thanks to everyone’s help.”

"Yes, I believe you can do it."

Himeko smiled gently, and the two looked at each other, having so much to say but not knowing where to begin. Suddenly, she asked, "Then... would you like to go to St. Freya for a visit?"

Kiana was slightly taken aback, but quickly nodded.

...

Inside the jewel, Himeko's consciousness was enough to alter the internal landscape; in an instant, they were already in that academy.

A verdant canopy stretched out, tender grass grew, and in the distance, rows of school buildings stood side by side, their marble doors towering high, while a fountain flowed quietly.

Himeko and Kiana strolled through the once-familiar school campus, a place most familiar to both teachers and students.

After all that has happened, I miss how it used to be.
