Kazama Naomi

She is the gorgeous social studies teacher who boast a great body that is far above most Japanese woman. She doesn't show her emotions and is unfazed by most things, making her the 'Ice Lady' to students and others.
Naomi doesn't talk until it is necessary and can only treat students by the books.
She is the adviser to the motorcycle club, which is on the verge of being discontinued, and uses her motorcycle to commute to work.
Despite her cold attitude, she is attached to her club, and opens her heart up to them, showing a face that others don't see.
