Eight days prior to its premiere in Japan, KADOKAWA’s official anime YouTube channel posted a 90-second creditless OP movie for the upcoming original TV anime MAESETSU! – Opening Act-.
The OP theme song “Pi-Pi-Pi Happy” is sung by the anime’s four main voice actresses – Aguri Ohnishi (Fubuki Kitakaze), Naomi Ozora (Mafuyu Kogarashi), Hiromi Igarashi (Rin Araya), and Sakura Nakamura (Nayuta Assougi).
The TV anime directed by Yu Nobuta (High School Fleet) was originally slated for July 2020, but has been postponed due to the COVID-19 pandemic.
