[ BB's gag with Otomes is her inert desire to force people into picking prompts to speak with her - because, even she knows, she is complicated and complex to talk to. Preserving humanity's small brains into simple prompts that make it so they can talk to her thusly - is her deranged way of connecting with those she thinks are below her. Or is desperate to want the other to know her.

Not to mention, she came forth from a place where prompts like that were the only way to speak to her - but that is neither here nor there. ]

They will always fear you because you are different, and closer to the unknown - hey, but did you know? Mortals fear the unknown as much as they love it ~ ♡!

[ Just like Mizuki she loves mortal kind for that exact reason, but more specifically because it is humans who despite all odds and what may come for them. They are willing to fight against it.

At the same time, they are their own worst enemies. Disgusting, decrepit, and foul beings that bring about their own ends and often regale at the other's sufferings. Within her she consumed such a thing, the whole of all human depravity. It sits in her stomach and engrossed in her data. All the things that make up the worst of humankind, consumed by her own existence.

As if it were a just meal. ]

Ne, ne? If something ever happens to me Mizuki, I want you to eat my body okay~ ♡ ?

[ Because they were just talking about that after all. ]

I wonder if you will feel the same about humans, once you eat me and taste the things that I have eaten.
