Kyoko's niece by marriage, she lived with her mother in Otonashi's house (but has never seen her dad). When she visited Ikkoku-kan with her grandpa to see how Kyoko was doing, she met Godai, and later when her family thought about getting a tutor for her, she insisted on Godai --- she was in the 6th
grade at that point. On the first day, Godai found out that it was more like a babysitting rather than a tutoring session. Thanks to Godai's tutoring, she managed to get into her first choice high school, and passed the college entrance exam in one shot --- probably because she knew a living example of a ronin. (Who else --- Godai-no-onichan!)(``Godai, my big brother'')
