Is it available online? How can I watch it for free?

However, since most new anime are available for catch-up streaming online, it is likely that “Mayonaka Heart Tune” will be available for online viewing as well.
Many anime series that are available for online streaming are announced on their websites or social media platforms one to two weeks before their terrestrial broadcast. “Mayonaka Heart Tune” is scheduled to air in January 2026, so if it is available for online streaming, the streaming information will likely be released in December 2025.
If it is decided to stream online, it may be streamed exclusively on a specific video service, or on multiple video services such as ABEMA, Netflix, Prime Video, and U-NEXT.
How to watch for free?
As of December 1, 2025, it has not been announced whether “Mayonaka Heart Tune” will be available for online streaming, and it is unclear whether it will be available to watch for free.
Depending on the video service, you can watch the latest episodes of new anime for free. Many of the new titles broadcast on ABEMA can be watched for free in real time, and the latest episodes may be available for free catch-up viewing for a limited time.
At this point, it is not yet known whether “Midnight Heart Tune” will be available to watch online, but if it is streamed on ABEMA, it may be possible to watch it for free.
How many episodes does the anime “Mayonaka Heart Tune” have? What parts of the original work does it cover?
As of the time of broadcast, it is unknown how many episodes the anime “Mayonaka Heart Tune” will have.
Generally, if a series is broadcast for one season (about three months), it will be produced with about 11 to 13 episodes, and if it is broadcast for two seasons (about six months), it will be made with about 22 to 26 episodes. Since most works are broadcast for one season, it’s just a guess, but I think “Mayonaka Heart Tune” will also be produced with about 11 to 13 episodes.
As of November 2025, 10 volumes of the original manga for “Mayonaka Heart Tune” have been released. When it comes to anime based on manga, it is common for the content of 4 to 5 volumes of the manga to be adapted into a single season.
If “Midnight Heart Tune” were to be a one-season series, it would likely cover the content up to the 32nd chapter, the last chapter of Volume 4 of the original manga, or if it were to be rushed. Some episodes were cut; it would cover the content up to the 44th chapter of Volume 6 of the manga, where the fireworks festival ends.

The story of the anime “Mayonaka Heart Tune.”
Fuurin High School is a co-educational school formed by the merger of a boys’ school and a girls’ school. Yamabuki Arisu, a second-year high school student, is the heir to the Yamabuki conglomerate and strives to be perfect in all areas, including academics and sports.
When she was in middle school, Arisu looked forward to the privately broadcast radio show “Mayonaka Heart Tune,” but one day the broadcast suddenly ended. Since then, Arisu has been searching for Apollo, the broadcaster of “Mayonaka Heart Tune.”
While listening to the school’s lunchtime announcements, Arisu hears a girl with a voice similar to Apollo’s. She rushes into the announcement room and finds four girls there.
