Erika Amane

Erika Amane serves as the cornerstone of the Kasumigaoka High School Judo Club and was once a senior to Towa Hiura during their middle school years. It was Erika who first introduced Towa to the world of judo. With judo at the very center of her life and an unbreakable resolve, she earned the nickname "judo machine" from the protagonist. Although a defeat in a selection match once caused a rift between her and Towa, she ultimately stood by her junior with formidable skill and unwavering passion.
