Kashoku no Shiro

A mysterious disease in which one day people suddenly rise back from the Underworld: The Withering Death. When Kiso, a newspaper journalist, starts investigating the strange disease, he is attacked by a grotesque-looking demon. The one who saves him is a girl he had met by chance... The girl, whom Kiso is peculiarly drawn to, for some reason calls herself a "Demon's Burning Light"...?
