NBC Universal announced on Saturday, July 18, 2026, that the second season of the television anime adaptation of Masakuni Igarashi’s Tune In to the Midnight Heart (Mayonaka Heart Tune) manga is slated for a 2027 release. The confirmation, made by NBC Universal, also revealed a mostly returning core staff and introduced additional cast members alongside a newly released visual. This development follows the successful conclusion of the anime’s first season earlier in the year, which garnered significant attention from fans of romantic comedies and slice-of-life narratives.
Expansion of the Yamabuki Family and New Voices
The upcoming season will introduce key new characters, primarily focusing on the expansion of the Yamabuki family, a central element in the series’ narrative. The newly announced cast members are:

Her addition suggests a significant role for Riina in the unfolding plot.
-
Kaede Hondo will portray Mito Yamabuki, Arisu’s younger sister. Mito is described as having a cheerful personality and a more relaxed demeanor compared to her hot-tempered older sister and eccentric older brother. Hondo has a growing portfolio of roles in acclaimed anime such as The Rising of the Shield Hero and Bocchi the Rock!, making her a fitting choice to embody Mito’s bright disposition.
The introduction of Arisu’s sisters is anticipated to deepen the exploration of his family life and provide new avenues for character development. Their presence is likely to influence Arisu’s personal journey and his quest to find the mysterious radio host, Apollo.
Returning Creative Powerhouse
The production of Tune In to the Midnight Heart‘s second season will benefit from the continued involvement of the key creative team that helmed the first season, ensuring a consistent artistic vision and quality.
-
Masayuki Takahashi is returning to direct the anime at Gekkō. Takahashi’s previous directorial work includes the anime Butareba: The Story of a Man Turned into a Pig, showcasing his ability to adapt diverse narratives. His return is a strong indicator of continuity in the show’s direction and visual style.
-
Yukie Sugawara will reprise her role as the script supervisor and writer. Sugawara’s extensive experience, including her work on series like Overlord and Kaguya-sama: Love Is War, has been instrumental in shaping the compelling storylines and character interactions of the first season. Her continued involvement promises further intricate plotting and engaging dialogue.
-
Tomoyuki Shitaya will once again serve as the character designer. Known for his contributions to beloved anime such as Food Wars! Shokugeki no Soma and Bakuman., Shitaya’s distinct art style has been a significant factor in the anime’s visual appeal.

Kuniyuki Takahashi is confirmed to return as the music composer, responsible for creating the auditory landscape of the series, which plays a crucial role in setting the emotional tone.
While the core creative team remains largely intact, there is a notable change in the color department. Akira Nagasaki has been appointed as the new color designer. Nagasaki previously contributed to the first season in color coordination, and his promotion signifies a new artistic direction for the color palette of the second season.

Notably, Crunchyroll also produced and streamed an English dub for the anime, further expanding its reach and appeal. The simulcast and subsequent English dub were well-received, contributing to the overall positive reception of the series.
The Enduring Appeal of the Manga Source Material
Tune In to the Midnight Heart is based on the manga by Masakuni Igarashi, a creator known for works like Senryū Girl and Detectives These Days Are Crazy!. The manga, which launched in Kodansha‘s Weekly Shōnen Magazine in September 2023, has been lauded for its blend of heartwarming storytelling, relatable characters, and a touch of mystery.
The official synopsis provided by Kodansha‘s K MANGA service, which publishes the manga digitally in English, describes the premise:
"When Arisu Yamabuki was all alone in bed at night, he was able to find solace in the voice of a radio host who went by ‘Apollo.’ However, one day, she simply stopped broadcasting without any explanation. Years then passed, and Arisu is now a second-year high-schooler. He makes it his mission to search for Apollo, as there is something he wants to tell her. He doesn’t know what she looks like, or even what her real name is, but he manages to get some leads on her in his school’s broadcasting club. That’s where he meets four girls who all dream to get a job where they can make full use of their voices! Just who is Apollo, and how will those four’s dreams pan out?"
This narrative framework, centered on Arisu’s search for a beloved radio personality and his encounters with aspiring voice actors, has resonated with readers and viewers alike. The manga’s serialization in a prominent magazine like Weekly Shōnen Magazine indicates its popularity within the Japanese market.
Manga Publication and Licensing
The manga’s continued success is further evidenced by its ongoing publication and licensing efforts. The 14th compiled book volume is scheduled for release on August 17, 2026, suggesting a steady pace of storytelling. Kodansha USA Publishing has licensed the manga for English-language release, demonstrating its international appeal. The eighth volume was released on July 7, 2026, indicating that the English translation is keeping pace with the Japanese releases, allowing international fans to follow the story closely. This dual success in both anime and manga formats underscores the franchise’s growing cultural footprint.
Analysis and Implications
The announcement of a second season for Tune In to the Midnight Heart is a positive development for fans and the anime industry. The confirmation of returning staff, particularly director Masayuki Takahashi and script supervisor Yukie Sugawara, suggests a commitment to maintaining the quality and thematic consistency that defined the first season. This continuity is often a crucial factor in audience retention and critical reception for anime sequels.
The introduction of Arisu’s sisters, Riina and Mito, promises to enrich the narrative by exploring the protagonist’s family dynamics more deeply. This expansion could lead to new character arcs, further comedic situations, and potentially more emotional depth as Arisu navigates his relationships and his search for Apollo. The casting of established voice actresses like Ami Koshimizu and Kaede Hondo for these roles further heightens anticipation, as their performances are expected to bring these new characters to life effectively.
The success of the first season, as indicated by its broadcast on major networks and its international streaming availability on Crunchyroll, highlights the growing global demand for well-crafted romantic comedy and slice-of-life anime. The availability of an English dub further broadened its accessibility. The continued licensing and publication of the manga by Kodansha USA Publishing ensures that the source material remains readily available to a wider audience, potentially driving interest in the anime’s return.
The visual released alongside the announcement, while not explicitly detailed in the provided information, typically serves as a key marketing tool, offering a glimpse into the season’s aesthetic and character focus.

It also suggests that NBC Universal, as a key player in anime distribution and production, sees significant potential for the franchise to grow its audience and revenue streams. The 2027 release window indicates a strategic planning process, allowing ample time for production and potential marketing campaigns.
The shift in color designer, while not a central plot point, represents a subtle evolution within the production. Color design is critical in establishing the mood and atmosphere of an anime, and Nagasaki’s experience in color coordination suggests a thoughtful approach to this aspect of the visual presentation. The fact that other main staff members are returning underscores a strong foundation for the production.
In conclusion, the announcement of Tune In to the Midnight Heart‘s second season is a testament to the anime’s successful first run and the enduring appeal of its source material. With a blend of returning talent and new additions, the series is poised to continue its narrative journey in 2027, offering fans more of the heartwarming stories and engaging characters they have come to love.
