A broadcasting club rom-com anime centered on the theme of "voice," depicting dreams, love, and youth.
About
Kourin High School has transitioned from an all-girls school to a co-ed institution. At the center of the story is the broadcasting club, where high school students who believe in the power of the "voice" pursue their respective dreams. The story features four heroines who aim to make a career out of their voices—as a singer, voice actress, VTuber, and announcer—depicting their efforts, setbacks, friendships, and romance. The protagonist, Arisu Yamabuki, enrolls in Kourin High to find "Apollo," an unidentified radio streamer who saved him during his middle school years, using only their voice as a clue to uncover the truth. The theme that "voice moves people's hearts and changes lives" runs throughout the work, featuring elements related to audio media such as broadcasting rooms, radio streaming, school announcements, live performances, and auditions. The mystery of Apollo's identity is a major draw, and the series carefully portrays not just romance, but also the challenge of pursuing dreams and personal growth. It is characterized by a warm yet bittersweet world that blends youth rom-com, human drama, and a story revolving around the "voice."
