Key information
An official YouTube live broadcast was held on September 11, the day before the first Spectacle Sphere Live event titled HOT BEAT REVOLUTION!! for Ensemble Stars!! Music. The stream featured voice actors Fumiya Imai and Tomoya Kosaka, who guided producers through a dress rehearsal viewing.
Preparation for the live feature inside the mobile application took about one minute through a simple download process explained during the stream. The Spectacle Sphere Live allows users to watch performances closely from within the app interface.
During the dress rehearsal, the hero-themed unit Ryuseitai performed RELAX PARADISE, led by Midori Takamine, and BREAK THE NORM, featuring Shinobu Sengoku. Viewers experienced features such as zoom controls, interactive angles, and stage elements like fire and counter-lighting.
Tomoya Kosaka apologized for excessive gyro camera movement that caused motion sickness on his app screen during the broadcast. The dress rehearsal did not retain an archive, leaving fans to anticipate the official performance day.
