The beginning is slow and might repel some readers. It picks up quickly, and follows Kanade Ariya on her path to becoming a professional ballet dancer, along with Shouko, Ema, and Sakura.
It looks like Cuvie did her research pretty well. There are numerous variations (ballet solos) that are included AND named correctly. In addition, I can find just a panel during a variation and find where it is in the actual variation. The author is very diligent with this. In fact, even the steps are named correctly, from simple terms such as pirouette and pointe, to all kinds of ballet terminology. I'm pretty satisfied
Kanade is a little irritating. She's quite shocked to find out that ballet steps are in French. Ballet schools originated in France. I suppose she didn't recognize the accent?
Other than that, it's very enjoyable. The terms aren't too burdening (although I don't speak for non-ballet dancers). Finding out what the future holds is very entertaining. The art is very gorgeous in terms of anatomy. Even little details, such as the required body types (they have those in ballet; that's why it's so secluded), are accounted for.
For me, it was a compelling read. Give this one a shot.
