Hideki Sohta is the former teacher of Aki's class. He is known by his students to be a "kind and caring" teacher, when in reality this is false. He is described as a suave and handsome man. He seems to have a hand fetish as well. Sohta wears a suit as his work uniform and parts his sand colored hair. While he was still attending high school, Sohta was considered unattractive and was bullied for it in school.
