The ace of Kasumigaoka High School's Judo Club, she graduated from Kawakita Junior High School and is a year older than Michi. Erika is in the 52kg class. She was Hiura's senior at Kitakawa, and is about the same size as her. 

~!She invited Hiura, who was shy, to join the judo club and taught her judo. He loses to the matured Hiura in the club's regular competition, and is forced to be an alternate for the rest of her junior high school career. She is a proud and somewhat overbearing character, but she takes very good care of the younger members, especially Senou, and it is thanks to her guidance that Hiura has become a national-level player. After graduation, she joins Kasumigaoka High School, where they compete against each other in the preliminary round of the inter-high school team competition. After the match, they praise each other for their good fight, apologize for their past misunderstanding, and reconcile, becoming good friends and rivals.!~

After one last tournament and an embarrassing loss in the final round, Michi decides to call it quits on the sport of judo. Between high school social activities and entrance exams, she’ll have no time to compete in the martial art she loves most, but putting aside old hobbies is a normal part of growing up. Still, the love of judo lingers—and it comes back full force when she meets her new classmate Towa, the girl who bested Michi in her final match! Towa wants to form a judo club at their school, but she’ll need new members to get it up and running. United by their love of judo, they’ll throw in their passions into the ring together and score ippon again!<br><br>

Aoi Koga is a Japanese voice actress affiliated with 81 Produce.

Koga had an interest in anime since her childhood, watching series such as Cardcaptor Sakura and Ojamajo Doremi. She first became interested in voice acting after watching the television program Okaasan to Issho and becoming fond of the puppet segments featured in the show. This made her want to "become friends with dolls" and, along with her interest in anime, helped her decide to pursue a career in entertainment. In pursuit of becoming a voice actress, Koga would take acting lessons at a vocational school in Fukuoka. Following this, she enrolled in the training school of the agency 81 Produce, becoming affiliated with them upon her finishing her training.
