Rebel Duet is indeed isekai, albeit a more western take on the genre.Is the story of this game count as "isekai" ?
I'll be including more flashbacks over the course of the game that flesh out the protagonist's backstory, so Earth isn't entirely out of the picture. Plus, Valerie is very interested in learning about the protagonist's world.
Succubi in Rebel Duet attain sexual energy through either lust or bodily fluids (semen, saliva, pussy juice). So, while both is preferable, it isn't necessary for Valerie to explicitly have sex as long as her partner feels a significant degree of lust.Also succubus get their energy by drinking human semen, yes? But I'm playing as a female protagonist so how does that work?
