The basic of this idea is about a world that has suddenly changed, and the 13th hour appeared. Every 13th hour all the people on this world, except one convent, suddenly changes and become creatures known as “Dominus” who alters the world. When the 13th hour ends, all the “Dominus” disappear and people change back the way they where before, not knowing what happened, as they don’t know about the words changes. When the “Dominus” creature dies that person also dies, in the accident or in the usual murder. The Convent of the “Saint Rosen Crest” is the only one that can see the changes, but can’t see the real world when it is in a normal state. “Saint Rosen Crest” Covent has determined to fight the “Dominus” and change the world the way it was before with the blessed powers of their “Custodia”. But the nuns who live in that convent not even expecting that the creatures they are killing are the real human beings, and some unusual powers and elements appeared in there bodies within them and uotside of this world...
