Also, something to note... I got the impression from her interview and other stuff that Anzu is trying to get her act together, so to speak. Or at least she seemed like she was actually making an attempt.
She's probably tied for my least favorite among the Cinderella Project because she's so lazy (why are you an idol?? I mean, royalties, but she's so smart she could get royalties a ton of other ways, like writing a book?) and is kind of just a blob, but with her character development she might move up a few tiers in my view.
