I don't mind random NTR black dudes/male gyarus myself, hell, I prefer them over ugly bastards and old men, the last two are one of the main reasons I dislike NTR as like 90% of NTR works prefer using them for some reason, I personally find my enjoyment of the sexy Hentai girl reduced massively if I have to start at disgusting slob born out of the artist/author's idea that only men like that can steal girls XD (Another of the reasons I never could really get that invested in the main plot of this game funnily enough
) I just don't like when ACTUAL established characters of a work are twisted because of stereotypes to be used as NTR men, especially if it's of a series I know firsthand as it feels even more insulting towards said people than the girl or the NTRd guy. Agil, case and point, is a great dude, loves his wife to death and probably wouldn't even consider any of the main cast as more than 'little girls', but because he's a big black dude NTR artists lately write him like fucking Asuna is the entire reason his character was made for, LOL
