Gu's a little spitfire and I love her for it. She's got "H!P front girl" written all over her, because she seems like the type that's good at everything she does. (a la Miki, Reina, Goto, etc.) There loads of talent to back up her confidence.
I'm hoping she'll grow as much as Yurina as well, with those lanky limbs or hers.
Wait a second...does she have a wonky eye!?
