The Many Sides of Voice Actor Radio(2020)

Yumiko Sato works as a voice actress with a stage name "Yasumi". She hides that she is a "Gyaru", plays an innocent character in front of the audience.
She respects Yuhi Yugure, who is also a voice actress and a highschooler. Yuhi's popularity is on the rise, and she had even done a concert in front of her fans.
Yumiko is anxious... it's her second year as a voice actress, and she has to be famous in a year or else she will have to quit this job.
One day, she is offered to be a cohost to a weekly radio program with Yuhi Yugure. The director of the program is totally excited... just because he knew that they were classmates!

Yumiko couldn't be more surprised--to know that Yuhi Yugure was Chika Watanabe, a grim-looking girl in her class!
