Unrelated to the film starring Natalie Portman, Yamagishi's Black Swan predates the Hollywood movie by 16 years

One-shot compilation of Yamagishi focusing on the psychology and turmoil of ballet dancers. Includes the following:

• Black Swan (黒鳥-ブラックスワン-, Kokucho - Black Swan) -
  The real-life choreographic genius George Balanchine took five wives during his lifetime, all of whom were his "muse," but none of them lasted long.
  The work depicts their anguish in the form of a monologue by his fourth wife, Maria Tallchief, a real-life ballet dancer also known for her Native American ancestry.
  In addition to Tallchief, Vera Zorina, his third wife, and Tanaquil Le Clercq, his fifth and last wife, also appear in the work. (description from wikipedia.ja)
