I have no idea. I've been assuming that Hana being "mu" is related to zie being gender-neutral, but sexuality is something else entirely of course. Though zie seems indifferent to Date, I gotta say. (Or maybe it's just that I don't like Date, he seems pretty creepy to me, in a cute bondage-gear-wearing kind of way.)

Oh yeah, that dude! He was cute, I forget his name.
