HoYoFair is a recurring community event and platform for fan art organized by HoYoverse, not a performing artist, musician, or band. According to the Genshin Impact Wiki, 'HoYoFair is a Recurring Event where members of the community create art to celebrate the anniversary of Genshin Impact.' The associated 'HoYoFairFan Concert' is a fan event, not an artist's own concert.
