We saw Hina walk in on Nitori building the Marisabot, and she immediately vanished from the story in mid-page. I have therefore come to the perfectly logical conclusion that she has a crush on Patchy and Nitori stuffed her inside the Marisabot in a ludicrously ill-conceived attempt to set them up together.
If Alice breaks the Marisa bot, then perhaps reality would set in for them. Though given the situation, I would think she's more likely to sic her on Patchouli.
This is awesome. Alice with Yuri vision(?), lol. Just watch, the robot Marisa is going to do something crazy causing Patchy and Alice to finally see what's going on.
