Sadayo Kawakami (Characters)

Sadayo Kawakami is a Japanese language teacher at Shujin Academy. She is also the homeroom teacher of Ren Amamiya, Ann Takamaki, and Yuuki Mishima in class 2-D.

She is a highly competent and professional teacher who never lets her ever-mounting stress and exhaustion show visibly. She is also quite laid-back and outspoken, once saying "crap" in class.
