MAPPA’s original animator-focused isekai anime ZENSHU is underway as part of the Winter 2025 season, and now a familiar voice is joining the cast. The official accounts announced the addition of none other than Mamoru Miyano, who will voice a pop star known as Ultimate Exister.
You can hear his song—”Ultimate Exister,” which is now available via streaming services and is coming along with the first ZENSHU Blu-ray in Japan on a bonus CD this March—and watch as he makes his appearance in episode 4 below.

There’s also some character art:
Mitsue Yamasaki of Sleepy Princess in the Demon Castle is helming the project as director, while the scripts are being penned by Kimiko Ueno of Astro Note. Yamasaki and Ueno, plus MAPPA itself, are all recognized together for the original idea. The person handling the task of assistant director is Sumie Noro, who directed Saint Cecilia and Pastor Lawrence. The music is being composed by Yukari Hashimoto, who is known for working on Komi Can’t Communicate.
Here’s how MAPPA describes it:
ZENSHU Plot
After graduating from high school, Natsuko Hirose starts her career as an animator. Her talent quickly flourishes, and she makes her debut as a director in no time. Her first anime becomes a massive hit, sparking a social phenomenon and earning her recognition as an up-and-coming genius director. Her next project is set to be a romantic comedy movie themed around first love! However, having never been in love herself, Natsuko struggles to understand the concept of first love, and as a result, she’s unable to create the storyboard, causing the movie production to come to a standstill.
