True, but it can get a bit trying when almost all the girl's roles are there as support for the boy's more central/involved roles, or rather, built specifically around the boy's roles or for them. It's a little more than a number's game when the girl's roles have to be connected to the boys and they are often brought into existence for the sake of the trio aspect (or to be the sole girl in an organization of 13). Especially when their corresponding boys have stories/focuses that are less involved with their female friends (Yes I'm talking about how Sora and Riku and everyone forgot Kairi existed in KH3D without any memory magic involved) . It seems like a pretty conscious writing choice, especially when nothing dictates that most of the characters have to be dudes, especially some of the one-note characters in the Org.
But that's a meta complaint. It's hard to blame the character directly for the roles they've been placed in, especially characters who aren't given the power/autonomy to break free of the roles they're in.
