People tends to treat female characters as if they are a special kind of character in battle shounen and go on and on about their representativeness in shounen manga, we already discussed it here many times. Mangas here, specially here I should say, don't have to have a greatly participative (participative = good, it seems) female character for the series to be considered a manga that handles female characters well. Like any other character, they have to be good characters when they are in the spotlight. Battle Shounen, particularly, have almost all of them, male protagonists for obvious reasons, they are the ones that must be participative, the rest of the characters, male or female, will have less screen time, there is no question about that. When they have the spotlight, however, they have to be well developed, I think that My Hero Academia does this well, for example, Uraraka x Bakugo battle is still the best battle I read in the series so far. Shokugeki no Soma also has good examples, I think that Megumi is a good female character, Erina as well, although a bit below and others. They are not the focal point, but when they are in the spotlight the plot is well constructed, therefore I'm satisfied.
