The Sacred Heart Convent for the Sisters of the Holy Sepulcher is not what one would expect from a group of nuns. Mother Superior taught all her girls that the Lord's flock does not have to be meek little lambs. In keeping with that philosophy, all the nuns were trained in forms of both armed and unarmed combat, but despite all their training, nothing could save them from the powerhouse known as the Deacon. When the newly appointed Caretaker, Sara – granddaughter of the original Caretaker and former nun in the convent – returned home after the battle between the Spirits of Vengeance and the rogue angel, Zadkiel, she found the nuns massacred. Only Mother Superior was barely alive to explain what transpired in Sara's absence before she passed on with the rest. Sara buried the deceased on the grounds of the convent before she decided to seek vengeance against their executioner.
It has not been revealed if all the members of the Sacred Heart Convent for the Sisters of the Holy Sepulcher have been killed.
