Ibuki, Kouko

伊吹公子

Kouko is Fuuko's older sister. She formerly taught art at Tomoya's school and treats everyone with kindness. Kouko is a familiar presence at the Furukawa Bakery, and Nagisa admires her greatly as her former art teacher. Currently, she is engaged to Yusuke Yoshino.

Spoiler

In the movie, Kouko served as a drama teacher rather than an art teacher. Together with Youhei and Tomoya, she helped supervise and revive the drama club for Nagisa.
