I won't spoil anymore after this. I rushed to post and should've presented the finished product instead.
I need ideas for rare characters with unique dialogue if anyone feels creative. Not scripted like Hana and Paula but rather personality wise. Rares will roll to appear 2.5% - 5% of the time and will have at least a unique hairstyle/outfit and dialogue. I need some to go along with Dva and Yorha, not necessarily crossover. Just anything you think would be interesting.
This may be asking too much, but what the hell, how about Darkness from Konosuba? (actually any of the main girls are welcome). There is probably plenty of existing art that could be used to assist in the creation, and since those are existing characters, the dialogue won't be hard to make up.
Aside for that...
Maybe some perverted women, the kind that comes with some overcoat and a blush, and you can discover that they are wearing some sort of fetish sex item beneath. like a skin tight leather suit, or bondage ropes, or have vibes/plugs inserted already, maybe a submissive type that has a leash and some sort of mark on her (like "use me" or something along those lines).
You can have them also be happy/excited when forced to leave without their clothing.
Other ideas elude me for now, but final though - maybe a type that acts disgusted/reluctant to do lewd things, being all patronizing, but after being penetrated becomes the complete opposite, admitting she wanted it badly and begging for more, maybe with an ahegao.
Well, I hope that served as some inspiration, and thank you so much. I really appreciate what you are doing. You are awesome. honestly.
