Isekai cast

Four girls wake up in an unfamiliar world, AKA they go through the phenomenon everyone, their mothers and their dogs call "isekai". They also have varying degrees of amnesia. Luckily, they were picked up by a team of elves who accepted letting them join it.

It isn't exactly a good team though, as half of the characters in this cast are bad people or at least do questionable/shady stuff. None of the natives believe they were originally humans, either, and 3/4 of the isekaid girls don't really care about knowing why they got sent to that world.

Without spoilering much, this happens in a place that you could say is an isolated and hidden continent or something like that, so the species and culture and even technology is very different there. It's mostly a medieval setting with some steampunk things and slight magitech, by the way.
