"Hello! i'm currently focusing on finishing the game and adding all the competitors, and the game isn't supposed to be as big as yandere simulator, it's just a little project me and a small team are working on so i don't plan on expanding the scope any further, thank you for understanding!"
That's what the DEV said abt changing Hazu's gender, so I think it's unlikely that there'll be such thing as changing characters' gender +_+;;;
