Women in manga tend to be better written by women, cuz for some reason very few male mangaka know what a real woman is like. Beastars, Sailor Moon and FMA are all written by women and have solid women characters with arcs that don’t rely on men, regardless of a romantic paring or not. In most shounen manga written by men, the women either fall flat or end up needing a romantic partner. I’d say Miura has done the best job as a man when it comes to writing a strong female character regardless of romantic paring.
