A returnee to Japan suffering from dissociative identity disorder. One is an ultimately Japanese woman named Kaede, a very gentle personality well-versed in Japanese culture. The other is a foreigner named Kaere who is disgusted by Japanese culture and touts the bizarre ways of the country she is from, which is America. Kaere is easily offended and constantly threatens to sue everyone. She unfortunately adopts the latter personality more often. Her given name derives from Japanese kaere, the imperative form of the verb kaeru (to return, to go back), and also from Kaela Kimura, a Japanese idol. She provides many panty shots, often with strange images on her panties. It is interesting to note that she possessed a third personality, a balance between the two, until she came to this class, and the students triggered a psychotic breakdown.
