Gameplay-wise, I plan to have her fightable at different stages of difficulty as part of optional training to learn some martial skills. I also plan her to be playable too in a few sections.
Story-wise, she will be important in some key moments (she'll have some h-scenes for that, of course).
I actually had an idea of making a game with her as the main character before I changed my mind and decided to start making this one with Skuffel, but even if Mako won't be the protagonist here, she'll still play an important role.
