Karuto shinja worship the bloom ,the pustules that infect people and statues alike, for the bloom is a disease that causes rebirth, after infection ,red pustule like growths appear as well as blood covered whiskers that grow in their eyes ,but a few days after infection their skin falls off like a cocoon ,and they become stronger ,and no longer covered in pustules, karuto  shinja wear a grey mask with slits for breathing ,and one eye hole, these masks have two horns on the top of the mask
