To promote the ongoing theatrical release in Japan, the official website for Tokyo 7th Sisters -Bokura wa Aozora ni Naru- (We will be the blue sky), the all-new anime feature film inspired by Donuts’ smartphone rhythm game Tokyo 7th Sisters, has posted a live performance clip of “KILL☆ER☆TUNE☆R,” which was introduced early in the film.
Due to its small number of theaters, it didn’t appear in the overall box office ranking but ranked second in Kogyo Tsushinsha’s min-theater ranking.
It was finally released in 20 theaters in Japan on February 26, 2021.
