Yamada Umeko, known by her stage name "Sawamiya Erina," is a 16-year-old idol who has gained fame through her appearances in commercials and as a new personality on the Hot-Blooded Banish Academy variety show. On the show, she co-hosts a segment focused on girls who play sports. Naturally athletic, Umeko had a different path before entering the world of idols.
Before becoming an idol, Umeko was a national-level kendoka. Her ability to score a point against Sakaki Ura earned her the title of the "second genius." However, her frustration at not being able to defeat Sakaki Ura led her to quit kendo. This decision marked a turning point in her life, leading her to pursue a career as an idol instead.
