Calamity Trigger

The Successor of the Azure (蒼の継承者), also known as the Calamity Trigger is the title of those who inherited the true Azure. The Successor is a perfected Boundary Interface Prime Field Device.

Noel Vermillion awoke as the Successor during the events of BlazBlue: Continuum Shift. Using the Eye of the Azure, she is the only being capable of locating the Amaterasu Unit within the infinite reaches of the Boundary.

Nu -No. 13-, after the process of assimilation between her and Noel, became a false Successor and became able to open the Nemesis Horizon and summon the Master Unit.

Judging by the name of a save file, when Hinata Himezuru transferred her Embryo to Es, the latter became a Successor.
