Tomoko Nomura

A student in Eikichi Onizuka's class, Tomoko Nomura has a large chest (her cup size is F), but is not too bright, leading to people calling her Toro-ko (Toro meaning "slow" in Japanese; she is nicknamed Slo-mo-ko in the English version). After initially messing up her role in one of Miyabi Aizawa's plans to get Onizuka fired, she is cut off from Miyabi's group.
