I typically choose the "Drama" category and added "post apocalyptic" on Webtoons, even though it is not quite accurate. I figured the target group would be similar as the world is pretty dystopian and populated by mutants. The apocalypse just didn't happen (yet?).
When asked I'd say my comic is a socialdrama. Something like that. The comic does deal with the protagonists of course, but how society shapes them and how the circumstances of their really shitty world affect them is a huuuuuge part of it. I also explore the backdrop of how mutants live in my world a lot through the protagonists.
You could also call it a dystopia as it plays somewhat in a futuristic setting and examines how the arrival of mutants has some really negative outcomes in society. I don't think it is entirely accurate, but a lot of the definition of "dystopia" fits, so there's that ^^
