Just saw a discussion about it and i remembered that i wanted to ask about this. Why in this game,the gender is A-B intead of Male-Female?

I saw few people that is saying that is for gender equality or something but i mean,the previous souls games wasnt sexist at all? I saw the same thing in Demon's Souls Remake and i wanted to ask about it.This post is not aggresive or something,please just answer like a human being if you know why instead of hating on me. Because i really unironically asking it
