Tang Yu lives anonymously in Esselburg, making a living by painting ordinary landscapes, trying to escape the tragic past of being wiped out by the tyrannical "Emerald Hegemony" because of his identity as the "Ember Fire" painting school. Karen, a member of the resistance organization "Breaking Dawn", found him and commissioned him to draw the truth about the "Silent Square" massacre that was covered up by the hegemony ten years ago. However, under the pursuit of the hegemony's secret agent "Obsidian Eye", Tang Yu realized that he had no way out, and finally made up his mind to accept the commission.
