Ibuki Yagami

The class-representative of Room 2-4 of the high school where Kyoko met Souichiro (the home-room teacher of 2-4 also happens to be Kyoko's home room teacher).

Ibuki met Godai when he was in the student teacher program in his fourth year of college, and shortly after fell in love with him. Despite Godai not being interested in her, she never gives up.
