I like Katagiri. The awful, complicated relationship she has with her father, and the way this affects, not only her personality, but also the way she interacts with other people is interesting. I want to see her happy, and I want her to prove her pathetic father wrong. But I'm going to be completely honest here: I really, REALLY couldn't care less about this Yamai kid, and it bothers me to see him become one of the focal characters in this spin-off.
