Based on community discussions, "KUNI Scans" typically refer to high-quality digital archives of Japanese artbooks, specifically those related to the series Houseki no Kuni (Land of the Lustrous). This collection likely spans multiple volumes of concept art, character sketches, and official illustrations.
