a side story from the original anime it show's the side story of the 7 shadows and its actually quite cute from the artstyle to the overall genre of this ona. Artstyle is great, its like Isekai Quartet type of Artstyle and i quite a fond of that style of style and story telling. Cute, Fast-phased and has a story but at the same time it doesn't because it just shows the behind the scenes. it doesn't really have the story and that's what it really meant to be, a breather from the original anime and shows what's happening behind the scenes that we normally don't see. Highly recommendedif you already watched the eminence of the shadow and needs a breathing of shadow-sama's Greatness
