- Iko Kirino wants to be a VTuber.

Why This Anime Is Worth Watching
-
Mystery + Romance: There’s a heartfelt mystery at the core - Arisu’s search for Apollo is emotional, and you don’t yet know which girl she is.
-
Voice-focused Dreams: Each girl has a career dream that involves “voice” (singer, voice actress, VTuber, announcer), which aligns beautifully with the radio/broadcasting club setting.
-
Character-Driven: Because Arisu supports them, the anime can explore each girl’s goals, insecurities, and growth.
-
Sound Matters: Since voice is central, music and sound design will likely play a major role - and the theme song by Suisei is already a draw.
-
Late Night Vibes: The “midnight” in the title, the radio broadcast, and Arisu’s solace in Apollo’s voice all give this series a moody, introspective feel.
What We Still Don’t Know (or Could Speculate)
- We don’t yet know how many episodes the first season will run.- It’s unclear which girl is Apollo - that mystery is likely going to drive a good portion of the plot.
- While the opening and ending themes are announced, we haven’t heard full-length versions yet (unless you’ve caught them in the trailers).
- The advance screening: The second PV revealed that the first two episodes will be shown early (January 4, 2026) at an event in Tokyo.
- How closely the anime will follow the manga - e.g., which arcs or plot points will be adapted first - remains to be seen.
Final Thoughts
If you’re into slice-of-life rom-coms with a touch of mystery and a deep appreciation for “voice” in all its forms, Tune In to the Midnight Heart is shaping up to be a compelling watch. The combination of Arisu’s personal quest, the broadcasting club’s ambitions, and thoughtful production staff makes it one to watch (pun intended) when it premieres in January 2026.
