Mayonaka Heart Tune

Hailing from a notable family, Arisu Yamabuki only accepts perfection. He constantly strives to maintain his flawless image, but there is more to him: Yamabuki used to tune in to the radio shows of a girl named Apollo and even confessed his love to her years ago. Ever since, he has been frantically searching for Apollo and her voice, but with little success.

However, when Yamabuki's school merges with an all-girls school, things begin to change. As the Broadcasting Club makes an announcement during the very first day, he is shocked to hear Apollo's voice, but there is a problem—all four members of the club sound like her! While each of the girls, Rikka Inohana, Shinobu Uzuki, Nene Himekawa, and Iko Kirino want to pursue their own careers with their voices, Yamabuki joins the club in the hope of identifying Apollo. Alongside his close observation, Yamabuki vows to guide the girls to greater heights.
