The very first Dimensional Boundary Prime Field Device that was sealed away in the Master Unit's coffin. She is from the first, original world. She is extremely fixated on Ragna even to the point where she made him into her Centralfiction (the "dream" which is monitored and observed by the Master Unit, Amaterasu, as well as the world that is constructed as a result.)  If he is gone, the world ends immediately, and as long as Ragna is present in the world, the Unit keeps using the Phenomenon Interventions with hoping to meet him – that is the reason why the timeline looped between AD 2100/01/01 to 2199/12/31, until the Calamity Trigger broke the loops by saving him./
