She is a childhood friend of Masato and has bullied him along with her sister, Serina. They have been estranged recently as she went to college and got a job in Tokyo, but she has now returned to marry a rich man. She has always been famous locally for her beautiful appearance and sharp intellect, and when she returns home, Masato's mother asks her to be his tutor. Her twisted nature does not improve even in Tokyo, and she uses her position as a tutor to bully Masato to relieve stress.
