Like all of the Caren Series, her appearance is based on Caren Hortensia.
Erice describes Caren as having "a slender build with voluptuous Hispanic curves". She wears no skirt or pants, leaving her underwear exposed, which everyone finds strange except Erice who thinks it's cool.
Caren is killed by Anubis and his companion during Nzambi's attack on the Grail Tournament. As she died she told Erice that the Holy Grail War was not yet over, and if Erice wished to fight, she must go to Fuyuki.
