Shiro Fujiwara is a third-year student of the high school and the president of the class. He is a very polite, responsible and somewhat conservative young man, besides, he wears glasses. Yonekuni Madarame describes Shiro's hairstyle as "old-fashioned".
Shiro Fujiwara studies at the same class as Yonekuni Madarame (who calls him simply "a Chairman") and, being "a monkey" (=raised in the family of "monkeys"), is Yonekuni's "temporary friend". The truth is, Shiro has had deep feelings towards Yonekuni ever since middle school.
