Well, I actually like her. Her unconditional hatred for the brother not so much. That's why I wanted to see her surprised face and how she would try to rebound from her earlier behaviour. Now that I've read, that it's the last volume, I see that the author is going for a fast wrap up. Too bad, as I can she a fun road of redemption for her. All she did until now was to bad mouth, scold and get in the way of the brother. The last one was dangerous, but she does not know that. So all in all, with the exception of being annoying for the reader, she isn't that bad and could have made a comeback. (Of course she wouldn't stand a chance in the end.) And as she really is still a brat, she could have outgrown that. Too bad there is now no time for that kind of development.
