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

Even though he had dressed as a woman and had the title of Lady Green Lily, he could still not care at all.

Amidst Otto's machinations, an unexpected event occurs, compounded by Apocalypse's identity...

He did his best to shield Karen from any potential exposure.

But no matter how ingenious a lie is, it will eventually be exposed.

...

"Heh—, is that the reason? I thought...the other party would also be happy about something like this."

Karen's smile was tinged with bitterness.

So, the initial stance was wrong?

Although she was touched by Otto's determination, she preferred someone who shared the same ideals. She didn't want him to do so many things just because of her smile.

"It seems... Otto really likes his grandma quite a bit~"

Theresa glanced at the screen, then at her grandmother, and said with a strange feeling.

"...Heh, maybe so. I've always considered him my best comrade-in-arms, and I've always believed that even after that incident."

Karen said softly, her eyes shining.

"However... women's clothing, placed on the Archbishop of Destiny... heh."

Rita covered her mouth and smiled, her eyes crinkling into a smile.

"Yes, Otto did wear it to lure the guards away. It must have been really tough on him. Surprisingly, it looked pretty good on him."

Karen quickly recovered from her sadness, struggling to find the right words, and a smile appeared on her face.

“Indeed, Bishop… I approve of Otto’s photos in women’s clothing.”

Luo Mo nodded in approval of Karen's words.

Otto, Walter, and Kevin—the three major organizations all have their own unique insights into cross-dressing… but he only dared to think about it in his mind.

...

That accident was the Black Death.

But along with the failure of the Eastern Expedition came not only inaction and exploitation at the highest levels, but also the spread of a terrible disease—the Black Death.

The Black Death swept across Europe, infecting countless civilians, and causing countless people to die every day...

Otto had no choice but to select either the minority or the majority, plus the protection of Karen…

See, it's pretty obvious what choice he'll make, isn't it?

After all, he would only choose Karen.

He only cares about Karen.

Otto's research was crucial, so even though the bishop knew his youngest son was protecting someone, he chose to turn a blind eye.

But he never expected that Karen would arrive at his experimental site so quickly.

And... what he was doing.

But this time, there was no prior arrangement from Otto; in the most important place in Destiny's destiny...

Karen, this time, is destined to be imprisoned.

Ultimately, was human experimentation conducted because of the Black Death?

The choice between the minority and the majority... is always necessary.

Otto back then was surprisingly innocent, though it seems... he remained the same later on, willing to do anything for Kallen.

He didn't ask any questions about Karen's choice; he simply offered his unconditional support.

Otto often recalls the scene from ten years ago.

That time, Karen's father died in battle, and he awakened the relics left by his ancestors—the Void Treasury known as the "Key of Revelation" in the pre-apocalyptic era.

Beneath the high, light-filled dome, Karen sobbed and wept, her face buried in the coffin containing her most important loved one.

Otto wanted to cheer her up.

Therefore, even if the condition set by the Divine Key was his own life, he was willing to exchange it.

Unexpectedly, this earned her a slap from Karen, her eyes slightly red as she looked at Otto.

Although her father died in battle, he protected the people and Otto... What is needed is not to bring him back by sacrificing one's life.

Her father... also didn't want to see this scene!

The situation from ten years ago has repeated itself, this time even more intense.

Otto breaks with Karen in prison; they disagree.

She couldn't accept Fate's actions at this moment, and Otto was no longer able to stop.

He didn't care about right or wrong, nor did he intend to argue about right and wrong, but he had to protect Karen under the mandate of heaven, and the only thing to blame was that he was too weak at the moment.
