Tune In to the Midnight Heart (Mayonaka Heart Tune) is based on the manga by Masakuni Igarashi, which sees a boy trying to identify the owner of the voice of a livestreamer he heard in the past. The manga debuted in 2023 in Kodansha’s Weekly Shonen Magazine and has 10 volumes as of September 2025.
Kodansha USA describes the manga’s premise as such:
At the end of a difficult day, the haughty but purehearted rich kid Arisu found his only solace in the voice of another girl his age, who hosted a livestream under the pseudonym “Apollo.” Then, one day, the broadcasts stopped. Arisu has dedicated the years since then to finding Apollo’s true identity, and he’s narrowed it down to one particular high school. He transfers in as a student and figures it’ll be a cinch–but then discovers it could be any of the girls in the broadcasting club! And the real Apollo isn’t talking for reasons of her own! These four girls have no use for Arisu’s personality, but they each harbor dreams of using their voices to build a career, and they sure could use his money… Can the blunt and blustering Arisu buy his way into the club’s good graces, and find the real girl attached to his dream voice.
