"Do you care about anyone that was born in this world?" You try to rephrase the question.

"Should I?" Herta blinks again. "The only one that really matters to me is you, Master. As much as I care about any kids we have together, and our great great grandkids, you're still more important than anything and anyone else, Master. If it was a choice between you and the rest of this world's life, I would always choose you. H-hey, don't look at me like that! Ouch! Stop pinching my cheek! I'm not some murderous psycho! I even helped destroy some magical corruption in this world! Which pretty much translates to making the world a better place for everyone anyway! Heck, if I see a demon I'd kill it on sight!" After you calm her down with some spanks and massages, she continues. "Ah, that felt good. Your hands are always so strong, Master... Wait, before I forget; I still like knowing more about the stuff I made. And it'd be sort of sad to see it all be destroyed. I just don't want anything to get in the way of what you and I both have, Master."

While Herta's worldview was unsurprisingly centered around her fetishes and devotion to you, as well as general indifference towards everyone else, a part of her was consistently adamant about purging demons and magical corruption. You knew that she'd always been tasked with planning/fighting against mental and magical corruption, and was familiar with how deadly it could be. But upon further questioning you find that she didn't particularly care about the fate of the world, thinking more in terms of how this would ruin the pureness of her fetishes and destroy your life.

"Why are you doing all of this?" Was another question that popped into your mind.

"What do you mean?" Herta tilted her head.

"All of the help you've been doing for me, all the devotion you show to me. Hell, you just helped me make a few aluminum ingots even though you said it wasn't gonna work out."

"Because I love you, Master." She didn't miss a beat. "I always will and I always have, since the day we first met."

It didn't take you by surprise, but it was a good reminder of how much she cared. How much all of your wives cared.

You decided to celebrate your success here by showering your first wife with love and attention.

And she, like always, happily took pleasure in being pushed around and bullied by you.

Bertha was excited about something.

She was practically dragging you around to show it to you. From what you gathered, she'd been able to do something with her [Custom Special], though what it could be was lost between her happiness. Until you both stop at her room and she opens a chest, nearly diving into it.

You didn't complain about the view she was giving you.

"Master, Master! Check it out!" Bertha takes something out of there and presents it to you with a simple flourish. "Ta-da!"

She acts as though she's holding something, yet nothing but air could be seen.

Except...
