The way last season ended and this one is beginning, I think Melissa is about to be railroaded into becoming the new heroine of the story. Complete the a harem to fawn over her, shelter her, etc. That's why Nine is being so overprotective. As the heroine, she isn't supposed to do things, she's just an object to be rescued. So I'm curious to see how Melissa retaliates and goes against whatever power governs this universe.
