OtaHub's take
CloverWorks does the animation, Shin Wakabayashi directs, Erika Yoshida writes the script and Yukiko Horiguchi designs the characters. Maaya Uchida voices Seika, Sayumi Suzushiro voices Nijika, and ANIMEC distributes in Japan. It was announced on November 1, 2026 and opens in Japan in 2027.
