The context

Nijisanji is one of Japan's largest and most prominent VTuber (virtual YouTuber) agencies, managing a diverse roster of virtual talent who stream, host live events, and release music. VTuber live concerts are elaborate productions featuring motion capture technology to bring the virtual idols to life on stage, often projected onto large screens. A key element of fan engagement at these events, especially for idol and music groups, is "call-and-response" (コーレス, *ko-res*). This interactive element involves the performers prompting the audience with specific calls, to which the audience responds with pre-rehearsed phrases or actions. The practice video released by Nijisanji is designed to help fans learn these cues, enhancing the collective experience and creating a powerful sense of unity between the VTubers and their audience at the live venue. The song "Yonaga Orchestra" is particularly known for its engaging call-and-response sections, making its inclusion and the preparation for it a significant highlight for fans.
