yourness is a Japanese group formed in September 2014. The project is credited to 古閑翔平, 黒川侑司, 小野貴寛, and 田中雄大, and its official website is yourness.jp.
Rather than relying on a heavily public-facing image, yourness is most easily identified through release credits and catalog listings. That makes the group useful for tracing songs, artist credits, and official releases back to the lineup behind the project.
