The only one I would have liked is the WE WISH one, since that was the first song I ever heard from her and was amazed. The other ones I wouldn't have thought much of, although I really love the Hanabi PV.
She looks so...normal there. She's a normal person singing a song while sad in the rain. So many people sing in the rain, it's good to see her do it, too (even if it is a PV and it's her own song lol).
