Biography
Tsuchigomori is a science teacher at Kamome Academy and Kou's homeroom teacher. In his teacher persona he appears caring and somewhat meek, though his true temperament is sarcastic, mischievous, short-tempered, and fond of unsettling jokes. Despite claiming otherwise, he genuinely cares about his students.
Story spoilers
Tsuchigomori is secretly a supernatural and the representative and curator of the academy's Fifth School Wonder, the 4PM Bookstacks. As curator, he can access knowledge of the school's past, present, and future and says he could alter the future, though doing so would erase the curator from existence.
