"The more I think about it, the more I know that what Yamiko and Eros had was real. I've been in a lot of relationships...only a couple times have I felt something like the chemistry those two built. And Yamiko...she finally opened up to someone. As much as I want to hate Eros, I have to admire him a little bit. Even I haven't gotten Yamiko to open up like that."
Yamiko's older sister and her closest confidant, Sayoko's outrageous personality can be a turn off to some people; but her kind personality is hard to ignore, and for her friends, Sayoko is always there with a shoulder to cry on and an offer to cheer a friend up with a night on the town. Sayoko is also an atrocious cook and a chronic flirt, often going out to bars and clubs in order to find a new boyfriend of the week.
When Eros becomes repentant about his cruel trickery toward Yamiko and joins the battle against Nemesis, Sayoko eventually chooses to help him and Yamiko reconcile once she realizes that his repentance is sincere and that his love and kindness may be what Yamiko needs to come out of her shell. Now, if only Sayoko herself could find that special someone at last..
