Shizuka Kamitani

Shizuka Kamitani is a middle school science teacher at Morinomiya Academy, the mother of Hayato and Taka and the ex-wife of high school chemistry teacher Taizo Hebihara. She has a general laid-back and very easygoing personality. She has a large amount of patience when dealing with her talkative and misbehaving son, Taka, sometimes gazing at him as a loving mother would, but becomes assertive and angry when she is rubbed the wrong way especially by her teenager son, Hayato, or ex-husband, Taizou. She has a tendency of hitting Hayato on the head when he does something foolish or disagreeable. Like Hayato, she extends this treatment to Usaida at times when he's slacking off on the job. She is an expert with children and finds both Kotaro and Ryuuichi to be cute and charming in particular, which she claims to be "unlike her own sons."
