Tune in to the Midnight Heart
Do you have a content creator or media personality you greatly admire? They may have a large following or only a few fans, but something about them resonates with you in a way that no one else does. One way or another, these presences matter to many people for a myriad of reasons. Perhaps they help alleviate the loneliness, teach you something new, provide more perspective, support you through tough times, and so on without even realizing it. So it is sometimes normal to wish to return the favor and show the star in question your support as well, reaching out to them in whatever harmless way possible. Humans are said to be social animals, after all, so seeking a connection that is important to you is part of the journey.
“Tune In to the Midnight Heart," also known as “Mayonaka Heart Tune," is a 12-episode TV anime series that aired from the 6th of January to the 24th of March in winter 2026. It was produced by Kodansha, KlockWorx, NBCUniversal Entertainment Japan, Avex Pictures, Sammy, Kansai TV, Crunchyroll, BS Asahi, and INSPION Edge and brought to life by Studio Gekkou. The main staff behind it includes Ozawa Fumihiro, Kurosu Nobuhiko, Murakami Takashi, and Azami Yuusaku as producers. Featuring the genres of Comedy and Romance alongside the themes of Harem and School, it targets the Shounen demographic. Each episode runs 23 minutes and has earned a PG-13 rating for teenagers 13 years or older.
The anime is based on the manga series of the same title, which began publication on the 20th of September 2023 and is still ongoing. It is the work of author and artist Igarashi Masakuni, which was serialized in the weekly Shounen Magazine. It was also published digitally as an English simulpub via K Manga, and Kodansha USA has been publishing the volumes since the 6th of May, 2025. Additionally, it has been published in Italian by Edizioni BD under the J-Pop imprint since the 14th of February 2025. A TV anime sequel titled “Tune In to the Midnight Heart Season 2” is also set for release, based on the manga, but no further information is known at the time of writing.
The story centers on Arisu Yamabuki, who, in his middle school days, found his one solace in life to be a radio show hosted by a mysterious girl known simply as "Apollo." As such, he would faithfully tune in to the program every single day until she suddenly stopped broadcasting altogether. While he had only a very few leads on Apollo's true identity, Yamabuki chose to investigate her thoroughly, which eventually led him to Furin High School, which had recently become co-ed, allowing him to enroll in hopes of finally finding her. Just like he suspected, the very first announcement the school’s broadcasting club made was indeed delivered by that familiar voice he so admires. But as he enters the club room for the first time, he realizes that his fated search is far from over, nor easy, for that matter. Why? The club’s four members, Rikka Inohana, Shinobu Uzuki, Nene Himekawa, and Iko Kirino, all somehow sound like Apollo in different ways. Thus, Yamabuki decides to join the club mainly to find Apollo, only to discover soon that all four girls dream of pursuing separate careers guided by their voices.
Despite these grand aspirations, there is ample room for improvement, and our MC takes it upon himself to help each of the girls reach their individual goals. This does not mean he will ever stop seeking out his favorite Apollo either…
I went into this series expecting another high school romcom with all the tired cliches the industry has worn out. But I was honestly surprised to find it did a fairly good job of getting me invested while also diverting some of the tired tropes. There were so many opportunities for said tropes to rear their ugly heads, but things take a unique, comedic turn here, primarily thanks to the MC’s distinct personality. I could guess the direction of the plot quite early, but it is refreshing to see the active progress Yamabuki makes towards his goals from one episode to the next. There is not a riveting and unpredictable story here, mainly because it is character-driven, and the conclusion is far from satisfying in my eyes. However, a second season is on the way, so there’s ample opportunity for the narrative to pick up and become more dynamic with its colorful cast.
The cake of the series is in the character department. Arisu Yamabuki is one of the biggest reasons I enjoyed this show as much as I did, because he isn’t your typical harem male MC. This man is charming and self-confident, and he comes from a loaded family—the whole package. Regardless, he was crestfallen when his beloved radio channel went off the air, as it meant he might never hear Apollo's voice again. Three years later, he makes solid progress on finding Apollo, but he also gains an important side quest: to help each girl achieve their dreams, as he does not want to see the goals associated with Apollo perish by any means. Rikka Inohana wishes to become a singer; Shinobu Uzuki wishes to become a broadcaster or announcer; Nene Himekawa wishes to become an actress; and Iko Kirino wishes to become a leading VTuber. Arisu is determined to help them all, solving problems along the way with way too much confidence at times. The girls aren’t as captivating, being far too easy to control, but that only made Arisu even more likable with his scary precision. Sometimes, all it takes is a little rage-baiting from this man to get the girls to shape up, and it’s hilarious to watch.
The art and animation department is a major letdown, which is unfortunate because the story and characters are so solid. The animation, in particular, is terrible, with little to no care or effort, and it fails miserably to connect the character movements to the background artwork. There are just so many noticeable animation errors in every single episode, with the glaring one being Arisu’s expressions not matching his voice lines at all. Some scenes lack animation altogether, and everyone moves so robotically that even the real motivations behind those actions lose their value. Meanwhile, character expressions look so awkward and choppy the majority of the time, which makes the generally appealing character designs look bad as well. I liked the clear-cut art style and vibrant color palette, which look sharp and beautiful in still shots, but here they absolutely waste their potential.
If it’s any consolation, the Sounds and Music department is pretty good and does some heavy lifting to make up for the visuals. Thank god because audio is one very pivotal aspect of a series like this! The opening theme is "Tsuki ni Mukatte Ute" by Suisei Hoshimachi, a VTuber herself, featuring saturated visuals of the main cast’s daily shenanigans alongside an upbeat, quirky tune you can vibe to. The Ending themes are "Koe no Kiseki" by Soala; "Bus ja Tsuki ni Ikenakute" by Momoko Seto (voice actress of Rikka), Rumi Ookubo (voice actress of Nene), Sayumi Suzushiro (voice actress of Iko), and Miku Itou (voice actress of Shinobu); and "ask for the moon" by Momoko Seto alone. All of these were lovely pieces that showed off just how multi-talented the voice actresses of the four girls were, but my favorite among them has to be "Koe no Kiseki" for how pleasant it is to listen to.
There are even some neat insert songs that really showcase Momoko Seto’s talent as a songstress, all of which I enjoyed. Needless to say, the entire voice cast is superb in bringing out the best in their characters, the good, the bad, and even the hilarious. I do like to point out that, despite the important question of “Which one is Apollo?" all the girls sound very different from each other, and you can easily tell which one hits closest to home based on what we’ve already heard of Apollo. This kind of ruined the whole Apollo mystery for me, as I felt it would’ve been better if they'd gotten one or two voice actresses with impressive range to voice all four girls, making the answer less obvious. Still, I’m also aware that it would’ve been tough to pull off successfully. The OSTs are largely forgettable, and even the sound effects lag, similar to the animation, but these things won’t ruin the whole show for you, unlike the animation.
Overall, “Tune in to the Midnight Heart” is carried by fun character interactions and a solid male MC who is confident and makes real-time progress towards his goals and those of others. The story is decent at best; the other characters aren’t anything special, and the animation is a giant turn-off, but at least the songs are great. I heard that the manga is extremely good, so if you’re genuinely interested in this series, it’s better to go there. But the anime is worth a watch if you genuinely enjoy the character dynamics and voice performances, not to mention that a second season is on the way. If not, walk away after an episode or two and indulge in something else.
