Shadows House Vol 10

From the Yen Press edition

In a mansion brimming with hope and cheer live those blessed enough to inhabit the pinnacle of nobility. Adored by the people, those dwelling at Mirror House begin another happy, joyous day…or so Kate Mirror would like to believe. But something is wrong with her body! Her face turned black, and she started emitting soot...but why? Isn’t she human?!
