Cecilia Armash (セシリア・アルマーシュ) is the mother of Calera Marker, and grandmother to the Maaka siblings. She is deceased prior to the events of the manga, and is only shown in flashbacks.
Cecilia's clan have been kept under lock and key by the Braunlichs for generations due to their line having the unique trait of producing the Spring of Psyche once every thousand years when the vampire race is in danger of extinction. She and James arranged the marriage of Calera and Henry. When she sent Calera away, she made her swear to never come back to the Armash home for the sake of her happiness.
Cecilia does not appear in the anime.
