Yay Noriko! I really like her and I think it's a shame that they didn't cover the time when she was briefly a member of Bad Luck in the anime. I like the detail with the sheets of music on the floor. Plus she's so purple so it's perfect.
I need to get a keyboard like that. Here's something you don't know about me. (And I don't care if you don't care.) I play the piano. I don't use music sheets. I play by ear. So hit me with any anime song and I can play it like that. Its not professional buts its great with someone who only learned what the keys are on a piano and kindergarten-level skills. Later I taught myself to play.
