I didn't know ninja dancing was a thing, let alone ninja dancing CGI. This is Enra, a Tokyo-based dance troupe that mixes dance rhythms, martial-arts influenced acrobatics, and computer graphics.
The group is spearheaded by Nobuyuki Hanabusa, who made a career of creating computer graphics for Japanese television shows and commercials. The performers have impressive resumes, too. One dancer, Tsuyoshi Kaseda, for example, played the green Power Ranger on Fox Kids.
