Claudia Hortensia

Claudia Hortensia is the deceased wife of Kirei Kotomine and mother of Caren Hortensia. Claudia was an albino and immune deficient, making it so that she could die from even a tiny wound. Her body always appeared tattered as a result. Caren inherited the aspect of "prone to be plagued by illnesses." Kirei thinks of Claudia as a saint, understanding his anger and remaining faithful in trying to save him. He believes nobody will ever understand him to such a degree as her.
