ETA: Toyonaga’s character will be named Katsuo Yuuri, Suwabe’s will be Victor Nikiforov (not sure about the spelling; looks Russian?), and a third character played by Uchiyama Koiki will be named Yuri Plisetski.
Miyamoto Kenji, who has choreographed for the top skaters in Japan, will be doing the choreography for the series.
