Ria Garnet Juiltyve

She is a world-class Russian figure skater and the favorite to win gold in at the Winter Olympics. As such, she is Tazusa's strongest rival. She also used the same song as Tazusa in episode 6, prompting her to revise her short program and shift to free jazz. She is a very quiet but dedicated figure skater worthy of her title. (Source: Wikipedia) She also has a name known to many "Queen of the Ice". She acknowledges Tazusa at the competition after her waitress performance.
