Niles is a character from the upcoming FE Fates game that is most noticeable for being able to be romanced by both the male and female avatar, so there's finally some direct LGBTQ+ representation in the series, which is very nice.
There's a female character that can be romanced by both genders too, but I'm sadly kind of meh about her.
Oh, that sounds great! n_n Personally I wouldn't have even though about LGBTQ+ needing to be represented in Fates, though I guess it'd be nice if the avatar could be gay, but w/e. It's awesome that they decided to add that touch though
