Mirio Nachi is a supporting character in the figure skating anime Medalist. She is a former competitive figure skater who now works as a head coach, operating a small team called the Gravity Sakura-dori Figure Skating Club in Nagoya. Her primary role in the story is as the personal coach of Ryoka Miketa, a promising young skater. Nachi specializes in jump technique and is known for her unconventional and lively coaching style. She communicates with a fun, teasing, and exaggerated manner that stands in contrast to more traditional figure skating coaches. However, her bold and outgoing personality often fades into bashfulness when she is around people she does not know well. Her appearance is marked by multiple piercings and short blonde or yellow hair that reaches her neck, with yellow eyes. Before becoming Ryoka’s coach, Nachi struggled to build strong connections with her former students at Meijo Crown Figure Skating Club. Her teaching methods and personality did not mesh well with them. With Ryoka, however, she found a student whose temperament and approach to skating aligned with her own, allowing her to develop a productive and positive working relationship. Nachi is motivated by her desire to help Ryoka reach her full potential and to run her own club successfully. Her background as a former skater gives her practical insight into the sport, and she serves as a jump specialist, providing technical guidance. While she does not undergo dramatic personal change over the course of the story, her role is essential in supporting Ryoka’s growth and in showcasing a different coaching philosophy within the competitive skating world.
