Dark Falz Gemini / Double from PSO2, because I genuinely love them.
Also has elements it can generate from some of the other Dark Falz due to group pictures being included.
I like to experiment with the concept of if they merged into one for their humanoid self by making them 1 girl.

I am unsure if it can generate their monster forms (castle, twins) but you can try. There wasn't much art of those forms.
