It has been revealed that Masakuni Igarashi's romantic comedy manga "Tune In to the Midnight Heart," currently being serialized in "Weekly Shonen Magazine" (Kodansha), will be adapted into a TV anime in 2026. The series is a "voice spring" romantic comedy about the heroines of the broadcasting club who work hard to achieve their dreams related to their "voice," such as becoming a singer, voice actress, VTuber, or announcer, and the protagonist who searches for radio broadcaster Apollo relying only on his "voice." Visuals and a promotional video featuring the four heroines have been released.
"Tune In to the Midnight Heart" is a manga by Igarashi, who is known for "Senryu Girl," which was also adapted into a TV anime, and began serialization in the magazine in September 2023. Yamabuki Arisu, a second-year high school student, is searching for a radio broadcaster girl named Apollo, whose face and real name she does not know, and gets a clue from the broadcasting club of the high school she is attending. There she finds four beautiful girls who dream of "getting a job related to voice"... This is a romantic comedy that begins with "voice." When the first episode was released on SNS, it became a hot topic, receiving a response of about 380,000 impressions.
Author Igarashi commented, "This work is based around the theme of voice, so from the planning stage I kept in mind that it would only be complete once it was turned into a film and the characters had voices. I hope that the charm of the girls' voices, which cannot be fully expressed in the manga, will be conveyed in the anime. I am also looking forward to hearing how Apollo's voice will turn out!"
The released PV has an impressive image with the four heroines saying "I love you". To commemorate the release of the PV, Official X will be running a "Who is the voice of the heroine?!" campaign. The PV was released with the cast name hidden, and participants will be able to guess the cast based on the voices of the four girls saying "I love you", and will be entered into a lottery to win autographed stickers from the cast.
A special corner for the series will be set up at the NBCUniversal booth at AnimeJapan 2025, which will be held at Tokyo Big Sight (Koto-ku, Tokyo) on March 22 and 23. There will be a huge wall of teaser visuals and an ASMR corner where you can listen to specially recorded voices. On the 23rd, an event will be held on the NBCUniversal booth stage, where the four cast members who will play the heroines will appear, entitled "Mayonaka Heart Tune Anime Adaptation Commemorative Stage - Why not start supporting your "voice"? -". The cast members who will play the heroines will be revealed, and new information is also scheduled to be announced.
