Suzuna Kuraki

A typical high school student, Suzuna Kuraki is the protagonist of the series. She is a delicate young woman, training to become a priestess of her Shinto ancestry so that she may properly consecrate her family shrine; a job traditionally bestowed upon the women of her lineage. Outside of her religious services, Suzuna generally behaves in a very aristocratic, conceited and fastidious manner, even though she is in fact the most apprehensive and solicitous person in the house. Suzuna is the obligatory fiancée of Koichi Hayama by arranged marriage, sister of Mizuna and daughter of Yuriko. (Wiki)
