Yeah I 1,000% fully support NB and agender representation when that is the intention. This is a doubling-down on a translator error. I respect their decision to translate the way they do, but it is factually incorrect- and one credits page does not mean they are in the right. It's icky to apply pronouns to someone when they don't fit with that person's gender identy, it's like refusing to call a trans person by their post-transition pronouns. Gross and disrespectful.
That said, I appreciate the work that the scanlators put into this manga and translation. One silly mistake doesn't invalidate plenty of good effort ^_^ too bad they made it a farce
