Production was put on hold following Gackt's announcement of an indefinite hiatus in September 2021, due to an early onset neurological disease that was progressing into a "life-threatening condition," resulting in dysphonia (disorder of the voice). However, Gackt made a slow recovery, and the film resumed production in October 2022.

Based on manga series "Tonde Saitama" by Mineo Maya (published from 1982 to 1983 in Japanese shojo manga magazine Hana to Yume).
