Holoearth is basically an official VRChat for vtuber fans.

Speaking to PC Gamer (through a translator) in a recent interview, the head of PR and Holoearth spokesman for Hololive’s parent company Cover, Ryota Aomi, said that Holoearth is “the next extension of the Hololive experience.” In other words, it’ll be a space where fans can be more than anonymous chatters during streams and hang out with their favorite vtubers using 3D avatars.
