Azumi Saeki

Youhei's senpai and girlfriend, and president of the wind ensemble club. At times finds showing her affection for Youhei in front of others embarrassing.

Eventually steps down as president of the club due to entrance exams and graduation, but is happy to see Youhei perform her previous role well in his own unique way.

It is implied that Anna in Bocchi na Bokura no Renai Jijou is in fact the daughter of Azumi and Youhei.
