I always watch these types of comic dubs on YouTube where they take lewd comics and dub them, but they never actually dub the full comic for censorship reasons. Like they always cut out the sex scenes, censor out the nudity and sex, and even cut out any obscene dialogue.
Unless the channel is connected to an account on an adult website, I don’t think there’s any plans for the whole comic to be dubbed.
Edit: Just found out it’s connected to a Patreon account, however it’s under review of the site’s Trust and Safety Team.
I don’t think it’s a short trailer for anything. I always watch these types of comic dubs on YouTub
