I'm alone in my vote.. Lovely.
My favorite minor character is actually Mia, the Headmaster's Remlit. I know you only see her, like, half a dozen times in the game, depending on how much investigation you do of Skyloft. But I like that her name is the acronym for "Missing in action". I found it clever. Also, I have a cat named Mia who reminds me very much of a Remlit, both in appearance and behavior. It feels almost as if they made the species just as a shout-out to me.
So, I voted for the instructors because one of them takes care of her, has cat furniture and toys strewn about his room, and mentions that he's falling in love with her and considering getting his own. Adorable.
It is a little scary how you can beat them, hurl them over a cliff or into water at night, and they will hover back to where you picked them up growling, with a demonic expression on their faces. :O
