Yukie Mishiro

She is an official from the Japan Skating Federation who claims that Tazusa has a “stone face.” In return Tazusa calls her Queen Nasty or Sarcastic the Third. However, she does believe that Tazusa has special potential, which is why she pushes her so hard. In the final episode she recognises the changes in Tazusa’s personality as she breaks her “stone face” in her final routine. She hints that there’s more to come from Tazusa and that she has only begun.
