Sadayo Kawakami
川上 貞代
She is a Japanese teacher and homeroom teacher of Class 2-D at Shujin Academy. She is shown to be very cautious and act coldly towards Ren Amamiya due to the fact that he has a criminal record to him and thought of him as nothing but a problem student, even going as far as asking for homeroom reassignment at first. She is symbolized by The Temperance tarot card.
