宇藤 スワナ

Shuuichi and Chizuru's cousin, she gets her blond hair and blue eyes from her mother. She also attends the same private all-girls school as Chizuru and has better grades than Chizuru.
While she has not done it it she is knowledgeable about **** sex due to watching western ****, and to her knowledge it has only been done in Japan as a form of contraception.
She is more bold than Chizuru but still gets embarrassed all the same.
