The existence of demons is a matter of belief for most people but not for Gallios Spero. Frightened as a child, he could see them lurking in the shadows and hiding behind the eyes of strangers. His mother said demons were the reason they were hiding in the renovated attic of Father Jacob's church. Living a life where every day is the same, Gallois believes he has no future. His only two friends are Ramiro, a soldier in the Vatican army and Ramiro's daughter Lisa. He is very close to them but he's never told them about the things he can see or do. Gallois' life changes for the worse when a satanic cult summons a demon and sends it after Father Jacob, in a plot to help demons cross over onto Earth's plane. An angel appears and asks him to play a role in stopping the invasion. Gallois agrees but to survive, he'll have to accept who he is.
