Sagano

A mysterious man with elaborate facial markings who casually dons what appears to be a bloody fox tail muffler. Sagano seemingly knows a good deal about both Yues identity and the source of Yues troubled dreams but he discloses no information. Sagano is often seen with a cold smirk on his face. Kurogitsune notes that the only time Sagano doesnt appear dangerous or threatening is when hes eating. Source: the manga habit
