There's READMEs included in the archive, and it comes in four languages: English, and machine-translated Japanese, Korean, and Chinese. They're mostly just there to chill and vibe with you! Aside from walking and running around, they do all sorts of things that aren't too distracting for you. HoloCouncil Shimejis are your desktop companions (in the form of the Hololive Council girls) that moves around your screen. Note: This isn't a game, this is an application.
