Suzuka Kurihara

Suzuka is a classmate and close friend of Illya, Nanaki, Tatsuko, and Mimi, later extending her circle to include Miyu Edelfelt and Chloe von Einzbern.

She is regarded as the most rational member of Illya's group of friends. Despite her level-headed nature, she can grow impatient with tedious tasks such as cooking, and she often shows frustration with the complicated dynamic she shares with her older sister.

A self-proclaimed fujoshi, Suzuka enjoys boys' love (BL) stories and occasionally imagines scenarios involving Shinji and Shirou. While much of her personal background remains unknown, it is noted that she frequently assists her sister in creating doujinshi for comic events.
