Here's the relevant fragment of a post-show interview with Mansai Nomura offering some insight into the way this version of Bolero was created.
"- In a previous conversation with Hanyu you said that we are a “culture of abbreviation”. What did you keep in mind when applying the culture of abbreviation to Bolero?
- It is true that Bolero was gradually stripped away as we tried various ways of creating it. It was originally based on the Sonbaso dance from Noh and Kyogen, but in the process of transforming it into a prayer for the Great East Japan Earthquake I took concrete images such as lifting up a child and asking for help, or saying that flowers will bloom even in times of hardship, that rain will fall, and that summer will come, but I also made some more abstract concepts, and ultimately I think it gives a glimpse into a life of a human being, and that from death we soar into the next life, which is what leads to the final jump. So when you watch it, it may seem very abstract, but if you watch it with that in mind, I think you’ll see something special, so I hope we can continue performing “Bolero” together. again."
I also recall from some different source that in this vision Yuzuru is enacting the divine messenger , a golden phoenix, sent in response to prayers to bring about consolation and rebirth.
