Yeah, S3 did a good job with making Chihiro out to be the one who gets the short end of the stick. It's good that the author decided to make her the true end rather than someone we'd all expect like Ayumi.
It still feels weird that TWGOK is ending next week. I've been actually keeping up with weekly for three years too and now it'll feel a little empty that something that used to be part of my weekly schedule is gone. ;_;
