A story starting with a certain broadcasting club president.
About
Yu Mashiro, a student in the General Education course, was living a peaceful high school life until one day, Sena Juuo—the Student Council President and top star of the Idol course—suddenly appointed her as the president of the "Broadcasting Club on the verge of abolition." Now, she spends her days in a constant state of panic and hardship. As students from the eccentric Idol course appear as radio guests, she finds herself at the mercy of their unrestrained behavior. Despite her complaints, she works hard to keep the show on track with her sharp retorts, showing a commendable and diligent side as she strives to fulfill her duties as president and radio MC.
Characters
An approachable girl who serves as the straight-man and voice of reason, often finding herself at the mercy of quirky idols. She has short hair with slightly flicked-out ends and wears headphones and hairpins. After being suddenly appointed as the president of the nearly-defunct Broadcasting Club by Sena Juuo, the Student Council President and top star of Hatsuboshi Academy, she is constantly flustered. Even while being dragged along by the wild antics of the Idol course students who guest on her radio show, she diligently provides the necessary commentary to keep the program moving. Despite her grumbling, she is a hardworking and earnest girl who takes her responsibilities as president and MC seriously. Since her club is usually quiet, she's happy to keep you company if you visit the clubroom.
