ANGELUS ~Akuma no Fukuin~

A business man in Peru and a girl visiting Japan both suddenly fall victim to a strange disease that turns the skin green and partially disfigures the face. The most unusual thing is that these two incidents occurred at the same time. Brian Pall, a journalist from the London Post, was on a flight to London when suddenly one of the passengers is struck with the same disease. These series of outbreaks have lead Brian and his partner, Eris Miler, to start their own investigation. Their discoveries eventually lead them going up against a mysterious religious group.
