CyberAgent’s mobile bishojo RPG Alternative Girls(オルタナティブガールズ)has recently introduced the VR Live function. The first song to be sung live in VR is "もっと Be My Power!" by "美弥花ちゃん" (CV: Ayana Taketatsu).
Alternative Girls is a game where players take the role of a leader and train girls who are called Alterna. The VR feature allows the players to interact with the girls intimately and enjoy songs as if attending a concert.
